Description

La présente invention concerne un dispositif d'arrêt, pour une charnière de véhicule, et un ensemble qui comprend ladite charnière et le dit dispositif d'arrêt.The present invention relates to a stop device, for a vehicle hinge, and an assembly which comprises said hinge and said stop device.

L'invention est relative au domaine de l'industrie automobile.The invention relates to the field of the automobile industry.

Au cours de la fabrication d'un véhicule, on prévoit généralement de maintenir les portes du véhicule fermées durant le convoyage et une étape de cataphorèse de la caisse, alors que l'on prévoit de maintenir les portes du véhicule ouvertes lors du peinturage sur les lignes. A cet effet, on prévoit d'immobiliser la charnière de chaque portière en y installant un arrêt de porte provisoire, tel que ceux décrits dans EP 1 561 890 A1 , FR 2 916 471 A1 ou FR 3 050 477 A1 . Une fois l'étape de fabrication effectuée, l'arrêt de porte provisoire est retiré de la charnière.During the manufacture of a vehicle, it is generally planned to keep the doors of the vehicle closed during the conveying and a stage of cataphoresis of the body, whereas it is planned to keep the doors of the vehicle open during painting on the lines. To this end, provision is made to immobilize the hinge of each door by installing a temporary door stopper, such as those described in EP 1 561 890 A1 , FR 2 916 471 A1 Or FR 3 050 477 A1 . Once the manufacturing step has been completed, the temporary door stopper is removed from the hinge.

Puisque la caisse du véhicule est susceptible de subir un procédé d'électrodéposition tel qu'une cataphorèse alors que l'arrêt de porte équipe la charnière, FR 3 050 477 A1 prévoit que l'arrêt de porte est dépourvu de matériau métallique pour éviter que la peinture ne se dépose sur l'arrêt de porte et forme ainsi des débris indésirables. Néanmoins, en l'absence de matériau métallique, il peut s'avérer difficile de concevoir un arrêt de porte dont la structure est suffisamment résistante, pour que l'arrêt de porte puisse être réutilisé, notamment en ce qui concerne l'organe d'encliquetage, qui se détériore généralement le plus rapidement.Since the body of the vehicle is likely to undergo an electroplating process such as cataphoresis while the door stop equips the hinge, FR 3 050 477 A1 provides for the door stopper to be free of metallic material to prevent paint from depositing on the door stopper and forming unwanted debris. Nevertheless, in the absence of metallic material, it may prove difficult to design a door stopper whose structure is sufficiently resistant, so that the door stopper can be reused, in particular as regards the organ of ratchet, which usually deteriorates the fastest.

L'invention vise donc à remédier aux inconvénients de l'art antérieur en proposant un nouveau dispositif d'arrêt, pour une charnière de véhicule, qui est structurellement plus résistant, tout en restant peu susceptible de favoriser le dépôt de débris lors d'étapes de fabrication du véhicule.The invention therefore aims to remedy the drawbacks of the prior art by proposing a new stop device, for a vehicle hinge, which is structurally more resistant, while remaining unlikely to favor the deposit of debris during steps vehicle manufacturing.

L'invention a pour objet un dispositif d'arrêt, pour une charnière de véhicule, la charnière de véhicule comprenant un arbre, un premier charnon et un deuxième charnon, les charnons étant pivotants l'un par rapport autour de l'arbre, le dispositif d'arrêt comprenant : un corps principal exempt de matériau métallique, par l'intermédiaire duquel le dispositif d'arrêt peut être monté sur la charnière de véhicule, en étant fixé en rotation par rapport au premier charnon, autour de l'arbre ; et un organe d'arrêt, qui, lorsque le dispositif d'arrêt est monté sur la charnière de véhicule, est configuré pour : autoriser le pivotement des charnons l'un par rapport à l'autre, lorsque les charnons sont orientés l'un par rapport à l'autre dans un secteur angulaire de libération, et s'opposer au pivotement des charnons l'un par rapport à l'autre, par coopération mécanique de l'organe d'arrêt avec un pion porté par le deuxième charnon, lorsque les charnons sont orientés l'un par rapport à l'autre dans une première orientation, hors du secteur angulaire de libération.The subject of the invention is a stopper device for a vehicle hinge, the vehicle hinge comprising a shaft, a first knuckle and a second knuckle, the knuckle being pivotable with respect to each other around the shaft, the stop device comprising: a main body free of metallic material, via which the stop device can be mounted on the vehicle hinge, being fixed in rotation with respect to the first knuckle, around the shaft; and a stop member, which, when the stop device is mounted on the vehicle hinge, is configured to: allow the pivoting of the knuckles relative to each other, when the knuckles are oriented one relative to each other in an angular sector of release, and to oppose the pivoting of the knuckles relative to each other, by mechanical cooperation of the stop member with a pin carried by the second knuckle, when the knuckle are oriented relative to each other in a first orientation, outside the angular sector of release.

Selon l'invention, le dispositif d'arrêt comprend une armature métallique, qui est solidaire du corps principal. Selon l'invention, l'armature métallique comprend une lame d'arrêt, appartenant à l'organe d'arrêt, par l'intermédiaire duquel l'organe d'arrêt coopère mécaniquement avec le pion pour s'opposer au pivotement des charnons, lorsque les charnons sont orientés dans la première orientation.According to the invention, the stop device comprises a metal frame, which is integral with the main body. According to the invention, the metal reinforcement comprises a stop blade, belonging to the stop member, by means of which the stop member cooperates mechanically with the pin to oppose the pivoting of the knuckles, when the knuckles are oriented in the first orientation.

Grâce à l'invention, l'armature métallique arme le corps principal pour renforcer structurellement le dispositif d'arrêt dans son ensemble et ainsi améliorer sa fiabilité. En particulier, la lame d'arrêt de l'armature métallique s'oppose elle-même au pivotement des charnons en coopérant avec le pion. La lame d'arrêt étant peu sensible à l'usure provoquée par le pion, comparativement au corps principal, le pivotement répété de la charnière jusqu'à la première orientation et/ou le long du secteur de libération use peu le dispositif d'arrêt. Toutefois, le corps principal étant exempt de matériau métallique, il ne favorise pas le dépôt de débris sur le dispositif d'arrêt durant la fabrication du véhicule, notamment au cours de l'étape de cataphorèse ou de peinturage. On peut facilement prévoir qu'une partie de l'armature métallique est dissimulée dans le corps principal, hormis éventuellement la partie en contact avec le pion, et/ou que l'armature métallique a une taille relativement réduite par rapport au corps principal, de sorte que peu de matériau métallique est susceptible de favoriser le dépôt de débris sur le dispositif d'arrêt.Thanks to the invention, the metal reinforcement arms the main body to structurally reinforce the stop device as a whole and thus improve its reliability. In particular, the stop blade of the metal frame itself opposes the pivoting of the knuckles by cooperating with the pin. The stop blade being insensitive to wear caused by the pin, compared to the main body, the repeated pivoting of the hinge to the first orientation and/or along the release sector wears the stop device little . However, the main body being free of metallic material, it does not favor the deposition of debris on the arresting device during the manufacture of the vehicle, in particular during the cataphoresis or painting step. It is easy to provide that part of the metal reinforcement is hidden in the main body, except possibly the part in contact with the pin, and/or that the metal reinforcement has a relatively small size compared to the main body, so that little metallic material is likely to promote the deposition of debris on the arresting device.

De préférence, la lame d'arrêt forme une première dent, qui est agencée pour que, lorsque les charnons sont orientés dans la première orientation, la première dent s'oppose à un pivotement des charnons vers le secteur angulaire de libération, par mise en butée du pion contre la première dent.Preferably, the stop blade forms a first tooth, which is arranged so that, when the knuckles are oriented in the first orientation, the first tooth opposes a pivoting of the knuckles towards the angular sector of release, by setting abutment of the pin against the first tooth.

Preferably, the second tooth is arranged so that, when the knuckles are oriented in the first orientation, the second tooth opposes a pivoting of the knuckles towards the angular sector of release, by abutment of the pin against the second tooth.

De préférence, le corps principal comprend un premier bras, qui appartient à l'organe d'arrêt et qui est agencé en regard d'une partie de la lame d'arrêt, de sorte que, lorsque les charnons sont orientés dans la première orientation, le pion est interposé entre le premier bras et ladite partie de la lame d'arrêt, et que le premier bras s'oppose à un pivotement des charnons vers le secteur angulaire de libération.Preferably, the main body comprises a first arm, which belongs to the stop member and which is arranged opposite a part of the stop blade, so that, when the knuckles are oriented in the first orientation , the pin is interposed between the first arm and said part of the stop blade, and that the first arm opposes pivoting of the knuckles towards the angular sector of release.

On prévoit de fixer la porte battante du véhicule sur le charnon 5.The knuckle 5 is preferably an opening knuckle, that is to say a knuckle which is mobile. It is planned to fix the hinged door of the vehicle to the knuckle 5.

Le charnon 5 comprend une plaque de support 27, par l'intermédiaire de laquelle il peut être fixé sur la porte battante. Pour cela, la plaque de support 27 comprend par exemple des orifices de fixation 33 qui la traversent, destinés à recevoir des vis de fixation et/ou des pions de centrage.The knuckle 5 comprises a support plate 27, via which it can be fixed to the swing door. For this, the support plate 27 comprises for example fixing holes 33 passing through it, intended to receive fixing screws and/or centering pins.

De préférence, l'arbre 7 traverse successivement les orifices 43, 21, 23 et 45, dans cet ordre, les branches 15 et 17 étant disposées entre les branches 29 et 31. Le corps 24 s'étend suivant l'axe X7, en étant par exemple de forme cylindrique à bas circulaire, coaxiale avec l'axe X7. Ainsi, les charnons 3 et 5 sont liés l'un à l'autre par l'intermédiaire de l'arbre 7. Les charnons 3 et 5 sont pivotants l'un par rapport à l'autre par l'intermédiaire de l'arbre 7, autour de l'axe X7. Ce pivotement s'effectue entre une orientation de fermeture P1, une orientation intermédiaire P3 et une orientation d'ouverture P2, des charnons 3 et 5 l'un par rapport à l'autre autour de l'axe X7. Les charnons 3 et 5 sont montrés dans l'orientation de fermeture P1 sur les figures 1 et 2. La figure 3 montre seulement le pion 81 de la charnière 1, lorsque les charnons 3 et 5 sont dans l'orientation de fermeture P1. La figure 3 montre aussi, en pointillés, le même pion référencé 81', lorsque les charnons 3 et 5 sont dans l'orientation d'ouverture P2. La figure 3 montre aussi, en pointillés, le même pion référencé 81", lorsque les charnons 3 et 5 sont dans l'orientation intermédiaire P3. L'orientation d'ouverture P2 correspond de préférence à un pivotement des charnons 3 et 5 d'un angle d'environ 70° l'un par rapport à l'autre, par rapport à l'orientation de fermeture P1. L'orientation intermédiaire P3 est intermédiaire entre l'orientation de fermeture P1 et l'orientation d'ouverture P2, et correspond par exemple à un angle d'environ 10° par rapport à l'orientation de fermeture P1.The shaft 7 comprises a body 24, which passes through the pivoting holes 21, 23, 43 and 45 of the knuckles 3 and 5. Preferably, the shaft 7 successively passes through the holes 43, 21, 23 and 45, in that order. , the branches 15 and 17 being arranged between the branches 29 and 31. The body 24 extends along the axis X7, being for example of cylindrical shape with a circular bottom, coaxial with the axis X7. Thus, the knuckles 3 and 5 are linked to each other via the shaft 7. The knuckles 3 and 5 are pivoted relative to each other via the shaft 7, around the X7 axis. This pivoting takes place between a closing orientation P1, an intermediate orientation P3 and an opening orientation P2, of the knuckles 3 and 5 relative to each other around the axis X7. Knuckles 3 and 5 are shown in the P1 closed orientation on the figure 1 And 2 . There picture 3 shows only pin 81 of hinge 1, when knuckles 3 and 5 are in the closing orientation P1. There picture 3 also shows, in dotted lines, the same pin referenced 81', when the knuckles 3 and 5 are in the opening orientation P2. There picture 3 also shows, in dotted lines, the same pin referenced 81", when the knuckles 3 and 5 are in the intermediate orientation P3. The opening orientation P2 preferably corresponds to a pivoting of the knuckles 3 and 5 by an angle d approximately 70° relative to each other, relative to the closing orientation P1. The intermediate orientation P3 is intermediate between the closing orientation P1 and the opening orientation P2, and corresponds by example at an angle of approximately 10° with respect to the closing orientation P1.

En variante, l'invention s'applique également au cas où l'orientation P1 correspond à une orientation d'ouverture de la charnière 1 alors que l'orientation P2 correspond à une orientation fermeture de la charnière 1.Alternatively, the invention also applies to the case where the orientation P1 corresponds to an opening orientation of the hinge 1 while the orientation P2 corresponds to a closing orientation of the hinge 1.

L'arbre 7 montré sur les figures 1, 2 et 3 est un arbre provisoire, c'est-à-dire un arbre non définitif qui est intégré à la charnière 1 seulement durant la fabrication du véhicule, en particulier pour les étapes de convoyage, de cataphorèse et de peinturage susmentionnées. Une fois la fabrication du véhicule achevée, ou pour le moins certaines étapes de fabrication du véhicule achevées, on remplace l'arbre provisoire par un arbre définitif, non représenté, qui reste ensuite à demeure sur le véhicule. En l'absence de l'arbre 7 provisoire, les charnons 3 et 5 sont montés privotants l'un par rapport à l'autre autour de l'arbre définitif, suivant le même axe X7.Shaft 7 shown on the figure 1 , 2 And 3 is a temporary shaft, that is to say a non-definitive shaft which is integrated into the hinge 1 only during the manufacture of the vehicle, in particular for the aforementioned conveying, cataphoresis and painting stages. Once the manufacture of the vehicle has been completed, or at least certain stages of manufacture of the vehicle have been completed, the temporary shaft is replaced by a definitive shaft, not shown, which then remains permanently on the vehicle. In the absence of the temporary shaft 7, the knuckles 3 and 5 are mounted privotating relative to each other around the final shaft, along the same axis X7.

La charnière 1, incluant l'arbre définitif, constitue un ensemble à demeure, c'est-à-dire qui reste sur le véhicule une fois la fabrication achevée. Le dispositif d'arrêt 9, ainsi que l'arbre provisoire 7, constitue un ensemble provisoire, qui est absent du véhicule une fois la fabrication terminée.The hinge 1, including the final shaft, constitutes a permanent assembly, that is to say which remains on the vehicle once manufacture has been completed. The stop device 9, as well as the temporary shaft 7, constitute a temporary assembly, which is absent from the vehicle once the manufacture is finished.

Le dispositif d'arrêt 9 est montré monté sur la charnière 1 sur les figures 1 et 2, monté sur l'arbre 7 et coopérant avec le pion 81 sur la figure 3, individuellement sur les figures 4 à 5, et coopérant avec le charnon 5 sur la figure 6.The stop device 9 is shown mounted on the hinge 1 on the figure 1 And 2 , mounted on the shaft 7 and cooperating with the pin 81 on the picture 3 , individually on the figures 4 to 5 , and cooperating with the knuckle 5 on the figure 6 .

Le dispositif d'arrêt 9 constitue une pièce rapportée sur l'ensemble à demeure susmentionné de la charnière 1. Le dispositif 9 est destiné à être équipé sur l'ensemble seulement en cours de fabrication du véhicule, afin de maintenir temporairement la charnière 1 et la porte dans leur orientation d'ouverture. Pendant, ou après, la fabrication du véhicule, le dispositif d'arrêt 9 est désolidarisé du véhicule concerné. Le dispositif 9 est ensuite optionnellement utilisé pour un autre véhicule en cours de fabrication.The stop device 9 constitutes a part attached to the aforementioned permanent assembly of the hinge 1. The device 9 is intended to be fitted to the assembly only during manufacture of the vehicle, in order to temporarily hold the hinge 1 and the door in their opening orientation. During or after the manufacture of the vehicle, the stop device 9 is detached from the vehicle concerned. The device 9 is then optionally used for another vehicle being manufactured.

Structurellement, le dispositif d'arrêt 9 est constitué par un corps principal 65 et par une armature métallique 66, qui sont solidaires, c'est-à-dire attachés l'un à l'autre.Structurally, the stop device 9 is constituted by a main body 65 and by a metal reinforcement 66, which are integral, that is to say attached to each other.

Le corps principal 65 est préférentiellement formé d'un seul tenant, dans un unique matériau exempt de matière métallique. Par exemple, le corps principal 65 est réalisé en matière plastique polymère, de préférence un polyamide tel qu'un polyamide 6.6. En variante, le corps principal 65 est réalisé en matériau composite, comprenant une matrice en matière plastique polymère, de préférence un polyamide tel qu'un polyamide 6.6, et un renfort, par exemple des fibres de verre, qui sont noyées dans la matrice. De préférence, l'arbre 7 est en acier trempé.The main body 65 is preferably formed in one piece, in a single material free of metallic material. For example, the main body 65 is made of polymeric plastic material, preferably a polyamide such as a polyamide 6.6. As a variant, the main body 65 is made of a composite material, comprising a polymer plastic matrix, preferably a polyamide such as a polyamide 6.6, and a reinforcement, for example glass fibers, which are embedded in the matrix. Preferably, the shaft 7 is made of hardened steel.

Au contraire, l'armature métallique 66 est réalisée en métal, tel qu'un acier inoxydable.On the contrary, the metal frame 66 is made of metal, such as stainless steel.

Pour la fabrication du dispositif d'arrêt 9, on prévoit avantageusement que le corps principal 65 est surmoulé sur l'armature métallique 66, formée au préalable, ce qui facilite la fabrication tout en assurant une solidarité fiable du corps 65 avec l'armature 66. Alternativement, le corps principal 65 et l'armature métallique 66 sont fabriqués séparément puis assemblés, par exemple par clipsage de l'armature 66 sur le corps 65.For the manufacture of the stop device 9, provision is advantageously made for the main body 65 to be molded over the metal reinforcement 66, formed beforehand, which facilitates manufacture while ensuring reliable solidarity of the body 65 with the reinforcement 66 Alternatively, the main body 65 and the metal frame 66 are manufactured separately and then assembled, for example by clipping the frame 66 onto the body 65.

L'armature métallique 66 vise à conférer au dispositif 9 une résistance structurelle élevée en l'armant, alors que le corps principal 65, qui constitue l'essentiel du volume du dispositif 9, fait que le dispositif 9 est globalement peu sensible au dépôt de particules indésirables lors du peinturage.The metal reinforcement 66 aims to give the device 9 a high structural strength by arming it, while the main body 65, which constitutes the bulk of the volume of the device 9, causes the device 9 to be generally insensitive to the deposition of unwanted particles when painting.

Fonctionnellement, le dispositif d'arrêt 9 comprend un orifice 67 et un organe d'arrêt 73, visibles notamment aux figures 3 à 5, et une surface antirotation 71, mieux visible sur les figures 5 et 6. L'orifice 67 et la surface antirotation 71 sont avantageusement entièrement formés par le corps principal 65, alors que l'organe d'arrêt 73 est avantageusement formé en partie par le corps principal 65 et en partie par l'armature métallique 66.Functionally, the stop device 9 comprises an orifice 67 and a stop member 73, visible in particular to figures 3 to 5 , and an anti-rotation surface 71, better visible on the figure 5 And 6 . The orifice 67 and the anti-rotation surface 71 are advantageously entirely formed by the main body 65, whereas the stop member 73 is advantageously formed partly by the main body 65 and partly by the metal reinforcement 66.

Le corps principal 65 comporte une partie centrale 100, qui présente un flanc 72 et un flanc 74, qui sont opposés et parallèles. Les flancs 72 et 74 sont perpendiculaires à l'axe X7. L'orifice 67 traverse le corps principal 65 de part en part, en particulier la partie centrale 100, en étant coaxialement traversé par l'axe X7. L'orifice 67 est donc entièrement formé par le corps principal 65. l'orifice 67. L'orifice 67 débouche du flanc 72 et du flanc 74. L'orifice 67 est configuré pour être enfilé sur l'arbre 7. Ainsi monté sur l'arbre 7, le dispositif d'arrêt 9 et le charnon 3 sont pivotants l'un par rapport à l'autre autour de l'axe X7.The main body 65 includes a central part 100, which has a side 72 and a side 74, which are opposed and parallel. The sides 72 and 74 are perpendicular to the axis X7. The orifice 67 crosses the main body 65 right through, in particular the central part 100, being coaxially crossed by the axis X7. The orifice 67 is therefore entirely formed by the main body 65. The orifice 67. The orifice 67 emerges from the flank 72 and the flank 74. The orifice 67 is configured to be threaded onto the shaft 7. Thus mounted on the shaft 7, the stop device 9 and the knuckle 3 are pivotable with respect to each other around the axis X7.

En particulier, l'orifice 67 du dispositif 9 est monté sur une partie intermédiaire 69 appartenant à l'arbre 7, la partie 69 étant visible en coupe sur la figure 3, ainsi que partiellement sur la figure 7. La partie intermédiaire 69 prolonge le corps 24 de l'arbre 7 suivant l'axe X7. La partie intermédiaire 69 présente avantageusement une forme cylindrique à base circulaire, dont le diamètre est plus grand que celui du corps 24. L'orifice 67 est avantageusement monté serré sur l'arbre 7, ici par l'intermédiaire de la partie 69, de sorte que le dispositif 9 est fixé axialement par rapport à la charnière, c'est-à-dire est empêché de translater suivant l'axe X7. Pour que le montage serré soit suffisant pour maintenir le dispositif 9 solidaire de l'arbre 7, tout en permettant son démontage de l'arbre 7 une fois les étapes de fabrication du véhicule effectuées, l'orifice 67 présente avantageusement des cannelures internes, visibles notamment sur les figures 3, 4 et 5. Les cannelures permettent avantageusement de prévoir que l'arbre 7 et le dispositif 9 sont d'abord retirés d'un bloc de la charnière 1, puisque l'arbre 7 et le dispositif 9 sont désolidarisés pour une utilisation ultérieure. Alternativement, les cannelures peuvent permettre de prévoir que l'arbre 7 et le dispositif 9 restent solidaires, et sont montés sur, et retirés de, la charnière 1 d'un seul bloc.In particular, the orifice 67 of the device 9 is mounted on an intermediate part 69 belonging to the shaft 7, the part 69 being visible in section on the picture 3 , as well as partially on the figure 7 . The intermediate part 69 extends the body 24 of the shaft 7 along the axis X7. The intermediate part 69 advantageously has a cylindrical shape with a circular base, the diameter of which is larger than that of the body 24. The orifice 67 is advantageously tightly mounted on the shaft 7, here by means of the part 69, of so that the device 9 is fixed axially with respect to the hinge, that is to say is prevented from translating along the axis X7. For the tight assembly to be sufficient to hold the device 9 secured to the shaft 7, while allowing its disassembly from the shaft 7 once the vehicle manufacturing steps have been carried out, the orifice 67 advantageously has internal grooves, visible especially on the figure 3 , 4 And 5 . The splines advantageously make it possible to provide that the shaft 7 and the device 9 are first withdrawn from a block of the hinge 1, since the shaft 7 and the device 9 are separated for later use. Alternatively, the splines can make it possible to provide that the shaft 7 and the device 9 remain integral, and are mounted on, and removed from, the hinge 1 in a single block.

L'arbre 7 comprend avantageusement une tête 25, qui prolonge la partie 69 suivant l'axe X7, de sorte que la partie 69 est intermédiaire entre le corps 24 et la tête 25. Lorsque le dispositif 9 est monté sur l'arbre 7, le dispositif 9 est axialement interposé entre la tête 25 et la branche 29 du charnon 5. En particulier, le dispositif 9 vient en appui contre le charnon 5 via le flanc 72, qui est tourné en direction des charnons 3 et 5 et qui s'appuie axialement contre la branche 29. Dans la direction opposée, le dispositif 9 vient en appui contre la tête 25 via le flanc 74, en particulier contre un épaulement formé par la tête 25. Le dispositif 9 est ainsi fixé suivant l'axe X7 par rapport au charnon 5 et à l'arbre 7.The shaft 7 advantageously comprises a head 25, which extends the part 69 along the axis X7, so that the part 69 is intermediate between the body 24 and the head 25. When the device 9 is mounted on the shaft 7, device 9 is axially interposed between head 25 and branch 29 of knuckle 5. In particular, device 9 bears against knuckle 5 via flank 72, which is turned in the direction of knuckle 3 and 5 and which presses axially against branch 29. In the opposite direction, device 9 comes to bear against head 25 via flank 74, in particular against a shoulder formed by head 25. Device 9 is thus fixed along axis X7 by relation to knuckle 5 and shaft 7.

De préférence, la tête 25 présente une forme, telle qu'une forme de chapeau, qui facilite la préhension de l'arbre 7 par l'intermédiaire de la tête 25, à la main ou à l'aide d'un outil tel qu'une pince, notamment pour extraire axialement l'arbre 7 des charnons 3 et 5.Preferably, the head 25 has a shape, such as a hat shape, which facilitates the gripping of the shaft 7 via the head 25, by hand or using a tool such as a clamp, in particular to extract the shaft 7 axially from the knuckle 3 and 5.

Comme visible sur les figures 5 et 6, la surface antirotation 71 du dispositif 9 est par exemple formée sur le flanc 72, plus généralement sur la partie centrale 100 du corps principal 65. La surface 71 est donc entièrement formée par le corps 65. La surface antirotation 71 se présente ici sous la forme d'une empreinte, qui est formée en creux sur le flanc 72. La surface antirotation 71 reçoit en son sein la branche 29 du charnon 5, comme montré sur la figure 6, et coopère mécaniquement avec la branche 29 pour empêcher une rotation du charnon 5 et du dispositif 9 l'un par rapport à l'autre autour de l'axe X7. Autrement dit, la branche 29 et la surface antirotation 71 ont une forme complémentaire. Ainsi, lorsque le charnon 5 est pivoté par rapport au charnon 3, le dispositif d'arrêt 9 décrit le même mouvement que le charnon 5 autour de l'axe X7. La surface antirotation 71 et le la branche 29 sont configurés pour que la rotation relative du dispositif 9 et du charnon 5 soit bloquée dans les deux sens autour de l'axe X7.As seen on the figure 5 And 6 , the anti-rotation surface 71 of the device 9 is for example formed on the side 72, more generally on the central part 100 of the main body 65. The surface 71 is therefore entirely formed by the body 65. The anti-rotation surface 71 is presented here under the form of an indentation, which is formed hollow on the side 72. The anti-rotation surface 71 receives within it the branch 29 of the knuckle 5, as shown in the figure 6 , and cooperates mechanically with the branch 29 to prevent rotation of the knuckle 5 and the device 9 with respect to each other around the axis X7. In other words, branch 29 and anti-rotation surface 71 have a complementary shape. Thus, when the knuckle 5 is pivoted with respect to the knuckle 3, the stop device 9 describes the same movement as the knuckle 5 around the axis X7. The anti-rotation surface 71 and the branch 29 are configured so that the relative rotation of the device 9 and the knuckle 5 is blocked in both directions around the axis X7.

En résumé, le dispositif 9 peut être monté sur la charnière, par enfilement de l'arbre 7 dans l'orifice 67, et par coopération antirotation entre le charnon 5 et la surface antirotation 71, de sorte que le dispositif 9 est fixe par rapport au charnon 5, ou pour le moins fixé en rotation par rapport au charnon 5 autour de l'axe X7.In summary, the device 9 can be mounted on the hinge, by threading the shaft 7 into the orifice 67, and by anti-rotation cooperation between the knuckle 5 and the anti-rotation surface 71, so that the device 9 is fixed relative to the knuckle 5, or at least fixed in rotation with respect to the knuckle 5 around the axis X7.

L'organe d'arrêt 73 est formé à la fois par une partie du corps principal 65, à savoir de préférence un bras 101 et un bras 102 appartenant au corps principal 65, et par une partie de l'armature 66, à savoir une lame d'arrêt 103 appartenant à l'armature 66. Grâce à cette structure renforcée par l'armature 66, l'organe d'arrêt 73, particulièrement sollicité durant l'utilisation du dispositif d'arrêt 9, est fiable et structurellement endurant.The stopper 73 is formed both by a part of the main body 65, namely preferably an arm 101 and an arm 102 belonging to the main body 65, and by a part of the frame 66, namely a stop blade 103 belonging to frame 66. Thanks to this structure reinforced by frame 66, stop member 73, which is particularly stressed during use of stop device 9, is reliable and structurally durable.

Lorsque le dispositif 9 est monté sur la charnière 1 comme illustré sur les figures 1 et 2, l'organe d'arrêt 73 est configuré pour s'opposer au pivotement des charnons 3 et 5 l'un par rapport à l'autre, lorsque les charnons sont positionnés dans l'une des orientations P1, P2 et P3. En d'autres termes, l'organe d'arrêt 73 fonctionne comme un organe d'indexation pour indexer l'orientation des charnons 3 et 5 aux orientations P1, P2 et P3. De préférence, l'orientation de fermeture P1 est adoptée pour le montage de la charnière 1 sur la caisse du véhicule. De préférence, l'orientation intermédiaire P3 est adoptée pour le convoyage et le passage en cataphorèse. De préférence, l'orientation ouverte P2 est adoptée pour le peinturage.When the device 9 is mounted on the hinge 1 as shown in the figure 1 And 2 , the stop member 73 is configured to oppose the pivoting of the knuckles 3 and 5 relative to each other, when the knuckles are positioned in one of the orientations P1, P2 and P3. In other words, the stop member 73 functions as an indexing member to index the orientation of the knuckles 3 and 5 to the orientations P1, P2 and P3. Preferably, the closing orientation P1 is adopted for mounting the hinge 1 on the body of the vehicle. Preferably, the intermediate orientation P3 is adopted for the conveying and the passage in cataphoresis. Preferably, the open orientation P2 is adopted for painting.

Lorsque l'organe d'arrêt 73 s'oppose au pivotement relatif des charnons 3 et 5, il maintient la charnière dans l'orientation P1, P2 ou P3 considérée. Dans cette situation, la porte du véhicule est donc maintenue par le dispositif d'arrêt 9 dans l'orientation de fermeture P1, dans l'orientation d'ouverture P2, ou dans l'orientation intermédiaire P3. Ainsi, de préférence, on ne peut pivoter les charnons 3 et 5 l'un par rapport à l'autre qu'en appliquant un effort suffisamment important sur la porte, pour vaincre le maintien opéré par le dispositif 9. Plus précisément, de préférence, en s'opposant ainsi à un pivotement relatif des charnons, l'organe d'arrêt 73 applique un couple de maintien sur le charnon 3, par rapport au charnon 5, autour de l'axe X7, qui peut être vaincu en appliquant un couple supérieur à ce couple de maintien sur les charnons 3 et 5, pour entraîner tout de même un pivotement des charnons 3 et 5 l'un par rapport à l'autre, hors de l'orientation P1, P2 ou P3 dans laquelle les charnons 3 et 5 étaient maintenus par le dispositif 9. Dans cette situation, l'organe d'arrêt 73 se déforme élastiquement, de sorte que le dispositif 9 n'est pas détérioré et peut ensuite à nouveau s'opposer au pivotement des charnons 3 et 5 lorsque les charnons atteignent à nouveau l'une des orientations P1, P2 ou P3.When the stop member 73 opposes the relative pivoting of the knuckles 3 and 5, it maintains the hinge in the orientation P1, P2 or P3 considered. In this situation, the vehicle door is therefore held by the stop device 9 in the orientation of closure P1, in the opening orientation P2, or in the intermediate orientation P3. Thus, preferably, the knuckles 3 and 5 can only be pivoted relative to each other by applying a sufficiently large force to the door, to overcome the holding effected by the device 9. More precisely, preferably , thus opposing a relative pivoting of the knuckle, the stop member 73 applies a holding torque on the knuckle 3, with respect to the knuckle 5, around the axis X7, which can be overcome by applying a torque greater than this holding torque on the knuckles 3 and 5, to cause all the same a pivoting of the knuckles 3 and 5 relative to each other, out of the orientation P1, P2 or P3 in which the knuckles 3 and 5 were held by the device 9. In this situation, the stop member 73 deforms elastically, so that the device 9 is not damaged and can then again oppose the pivoting of the knuckles 3 and 5 when the knuckles again reach one of the orientations P1, P2 or P3.

On peut prévoir que l'organe d'arrêt 73 s'oppose au pivotement des charnons pour les trois orientations P1, P2 et P3 susmentionnées, ou, en variante, pour une seule orientation, ou pour un nombre d'orientations distinctes prédéterminé différent de trois.It is possible to provide that the stop member 73 opposes the pivoting of the knuckles for the three orientations P1, P2 and P3 mentioned above, or, as a variant, for a single orientation, or for a number of distinct predetermined orientations different from three.

Lorsque le dispositif 9 est monté sur la charnière 1, l'organe d'arrêt 73 est configuré pour autoriser le pivotement des charnons 3 et 5 l'un par rapport à l'autre autour de l'arbre 7, lorsque les charnons 3 et 5 sont positionnés l'un par rapport à l'autre dans un secteur angulaire de libération S0, qui est une plage angulaire continue, montrée sur la figure 3. Ici, le secteur de libération S0 est intermédiaire entre les orientations P1 et P2, en particulier intermédiaire entre les orientations P3 et P2. Les orientations P1, P2 et P3 sont toutes distinctes les unes des autres, et le secteur de libération S0 est distinct des orientations P1, P2 et P3, c'est-à-dire que ces orientations P1, P2 et P3 sont hors du secteur de libération. Par « autoriser le pivotement des charnons », on entend que l'organe d'arrêt 73 ne s'oppose pas au pivotement des charnons 3 et 5, c'est-à-dire les laisse libre de pivoter, ou pour le moins ne s'oppose à leur pivotement que de manière marginale, comparativement au cas où les charnons sont dans l'une des orientations P1, P2 et P3.When the device 9 is mounted on the hinge 1, the stop member 73 is configured to allow the pivoting of the knuckles 3 and 5 relative to each other around the shaft 7, when the knuckles 3 and 5 are positioned relative to each other in an angular sector of release S0, which is a continuous angular range, shown on the picture 3 . Here, the release sector S0 is intermediate between the orientations P1 and P2, in particular intermediate between the orientations P3 and P2. The orientations P1, P2 and P3 are all distinct from each other, and the release sector S0 is distinct from the orientations P1, P2 and P3, i.e. these orientations P1, P2 and P3 are outside the sector of liberation. By “allowing the pivoting of the knuckles”, is meant that the stop member 73 does not oppose the pivoting of the knuckles 3 and 5, that is to say leaves them free to pivot, or at least does not opposes their pivoting only marginally, compared to the case where the knuckles are in one of the orientations P1, P2 and P3.

Lorsque le dispositif 9 est monté sur la charnière 1, l'organe d'arrêt 73 est configuré pour autoriser le pivotement des charnons 3 et 5 l'un par rapport à l'autre autour de l'arbre 7, lorsque les charnons 3 et 5 sont positionnés l'un par rapport à l'autre dans un secteur angulaire de libération S1, qui est une plage angulaire continue, montrée sur la figure 3. Ici, le secteur de libération S1 est intermédiaire entre les orientations P1 et P3. Le secteur de libération S1 est distinct du secteur S0 et est distinct des orientations P1, P2 et P3.When the device 9 is mounted on the hinge 1, the stop member 73 is configured to allow the pivoting of the knuckles 3 and 5 relative to each other around the shaft 7, when the knuckles 3 and 5 are positioned relative to each other in an angular sector of release S1, which is a continuous angular range, shown on the picture 3 . Here, the release sector S1 is intermediate between the orientations P1 and P3. The release sector S1 is distinct from the sector S0 and is distinct from the orientations P1, P2 and P3.

On peut prévoir que l'organe d'arrêt 73 s'oppose au pivotement des charnons pour le seul secteur angulaire de libération S0 susmentionné, ou, en variante, pour davantage de secteurs angulaires de libération distincts prédéterminés, deux secteurs de libération successifs étant l'un de l'autre par une orientation où l'organe d'arrêt 73 s'oppose au pivotement des charnons 3 et 5.Provision can be made for the stop member 73 to oppose the pivoting of the knuckles for the aforementioned angular release sector S0 alone, or, alternatively, for more distinct predetermined angular release sectors, two release sectors successive being one another by an orientation where the stop member 73 opposes the pivoting of the knuckles 3 and 5.

Comme montré sur les figures 1 et 3, pour s'opposer au pivotement des charnons 3 et 5, l'organe d'arrêt 73 coopère mécaniquement avec le pion 81 porté par le charnon 3, par exemple en le pinçant. Pour autoriser le pivotement, l'organe d'arrêt 73 libère le pion 81, notamment en coulissant contre le pion 81. Autrement dit, c'est par l'intermédiaire du pion 81 que l'organe d'arrêt 73 retient les charnons dans leur orientation P1, P2 ou P3, ou libère le pivotement des charnons pour les secteurs angulaires de libération S0 et S1.As shown on the figure 1 And 3 , to oppose the pivoting of the knuckle 3 and 5, the stop member 73 cooperates mechanically with the pin 81 carried by the knuckle 3, for example by pinching it. To authorize pivoting, the stopper 73 releases the pin 81, in particular by sliding against the pin 81. In other words, it is through the pin 81 that the stopper 73 retains the knuckles in their orientation P1, P2 or P3, or releases the pivoting of the knuckles for the angular release sectors S0 and S1.

Structurellement, le corps principal 65 définit une ouïe 104, pour la circulation du pion 81 lors du pivotement des charnons 3 et 5. L'ouïe 104 est un orifice qui est traversant parallèlement à l'axe X7 et donc à l'axe X11. L'ouïe 104 est de forme oblongue et courbe. Autrement dit, l'ouïe 104 traverse le corps principal 65 parallèlement à l'axe X7 et qui est en forme d'arc de cercle autour de l'axe X7. L'ouïe 104 est délimitée, radialement sur l'intérieur, par la partie centrale 100 du corps principal 65, et, radialement sur l'extérieur, successivement par le bras 101 et par le bras 102.Structurally, the main body 65 defines an opening 104, for the circulation of the pin 81 during the pivoting of the knuckles 3 and 5. The opening 104 is an orifice which passes through parallel to the axis X7 and therefore to the axis X11. Hearing 104 is oblong and curved. In other words, the hearing 104 passes through the main body 65 parallel to the axis X7 and which is in the shape of an arc of a circle around the axis X7. The hearing 104 is delimited, radially on the inside, by the central part 100 of the main body 65, and, radially on the outside, successively by the arm 101 and by the arm 102.

Pour que l'organe d'arrêt 73 s'oppose ou autorise le pivotement des charnons 3 et 5, on prévoit avantageusement qu'une coopération mécanique s'opère entre le pion 81 et le corps principal 65, à savoir entre le pion 81 et l'ouïe 104, notamment via les bras 101 et 102.So that the stop member 73 opposes or authorizes the pivoting of the knuckles 3 and 5, provision is advantageously made for mechanical cooperation to take place between the pin 81 and the main body 65, namely between the pin 81 and hearing 104, in particular via the arms 101 and 102.

Chaque bras 101 et 102 est fixement attaché à la partie centrale 100 de façon radiale par rapport à l'axe X7, en étant venu de matière avec la partie centrale 100. Chaque bras 101 et 102 est recourbé, suivant un plan orthogonal à l'axe X7, le bras 101 étant recourbé en direction du bras 102, et le bras 102 étant recourbé en direction du bras 101. Autrement dit, chaque bras 101 et 102 présente une forme de crochet, qui entoure l'une des extrémités respectives de l'ouïe 104, pour la délimiter. Les deux crochets se font face, s'ouvrant en direction l'un de l'autre.Each arm 101 and 102 is fixedly attached to the central part 100 radially with respect to the axis X7, being integral with the central part 100. Each arm 101 and 102 is curved, following a plane orthogonal to the axis X7, the arm 101 being curved in the direction of the arm 102, and the arm 102 being curved in the direction of the arm 101. In other words, each arm 101 and 102 has the shape of a hook, which surrounds one of the respective ends of the hearing 104, to delimit it. The two hooks face each other, opening towards each other.

Lorsque les charnons 3 et 5 sont dans l'orientation P1, le bras 101 entoure le pion 81 de façon à l'accrocher, pour ainsi s'opposer au pivotement relatif des charnons 3 et 5 lorsqu'ils sont dans l'orientation P1. Pour cela, de préférence, le bras 101 présente avantageusement une dent 106, qui est tournée radialement vers l'intérieur, c'est-à-dire en direction de l'axe X7. La dent 106 constitue un obstacle que le pion 81 doit franchir pour autoriser les charnons 3 et 5 à pivoter par-delà l'orientation P1, en direction du secteur S1, de l'orientation P3, du secteur S0 et de l'orientation P2. Autrement dit, le pion 81 vient alors en butée orthoradiale contre la dent 106 pour l'orientation P1. Réciproquement, la dent 106 constitue un obstacle que le pion 81 doit franchir pour autoriser les charnons 3 et 5 à pivoter jusqu'à l'orientation P1, alors que les charnons étaient dans le secteur S1, dans l'orientation P3, dans le secteur S0 ou dans l'orientation P2. Le franchissement de la dent 106 par le pion 81 est effectué par déformation élastique du bras 101, suivant une direction radiale externe, et avantageusement de la lame 103, suivant une direction radiale interne.When the knuckles 3 and 5 are in the orientation P1, the arm 101 surrounds the pin 81 so as to hook it, thus opposing the relative pivoting of the knuckles 3 and 5 when they are in the orientation P1. For this, the arm 101 preferably has a tooth 106, which is turned radially inwards, that is to say in the direction of the axis X7. Tooth 106 constitutes an obstacle that pin 81 must cross to allow knuckles 3 and 5 to pivot beyond orientation P1, towards sector S1, orientation P3, sector S0 and orientation P2 . In other words, pin 81 then comes into orthoradial abutment against tooth 106 for orientation P1. Conversely, tooth 106 constitutes an obstacle that pin 81 must cross to allow knuckles 3 and 5 to pivot to orientation P1, while the knuckles were in sector S1, in orientation P3, in sector S0 or in orientation P2. The crossing of the tooth 106 by the pin 81 is effected by elastic deformation of the arm 101, in an external radial direction, and advantageously of the blade 103, in an internal radial direction.

Lorsque les charnons 3 et 5 sont dans l'orientation P3, le bras 101 entoure le pion 81 de façon à l'accrocher, pour ainsi s'opposer au pivotement relatif des charnons 3 et 5 lorsqu'ils sont dans l'orientation P3. Pour cela, de préférence, le bras 101 présente avantageusement la dent 106 et une dent 107. La dent 107 est tournée radialement vers l'intérieur, c'est-à-dire en direction de l'axe X7. La dent 106 constitue un obstacle que le pion 81 doit franchir pour autoriser les charnons 3 et 5 à pivoter par-delà l'orientation P3, en direction du secteur S1 et de l'orientation P1. Autrement dit, le pion 81 vient alors en butée orthoradiale contre la dent 106 pour l'orientation P3. Réciproquement, la dent 106 constitue un obstacle que le pion 81 doit franchir pour autoriser les charnons 3 et 5 à pivoter jusqu'à l'orientation P3, alors que les charnons étaient dans le secteur S1 ou dans l'orientation P1. La dent 107 constitue un obstacle que le pion 81 doit franchir pour autoriser les charnons 3 et 5 à pivoter par-delà l'orientation P3, en direction du secteur S0 et de l'orientation P2. Autrement dit, le pion 81 vient alors en butée orthoradiale contre la dent 107 pour l'orientation P3, de sorte à être capturé entre les dents 106 et 107. Réciproquement, la dent 107 constitue un obstacle que le pion 81 doit franchir pour autoriser les charnons 3 et 5 à pivoter jusqu'à l'orientation P3, alors que les charnons étaient dans l'orientation P2 ou dans le secteur S0. Le franchissement de la dent 107 par le pion 81 est effectué par déformation élastique du bras 101, suivant une direction radiale externe, et avantageusement de la lame 103, suivant une direction radiale interne.When the knuckles 3 and 5 are in the orientation P3, the arm 101 surrounds the pin 81 so as to hook it, thus opposing the relative pivoting of the knuckles 3 and 5 when they are in the orientation P3. For this, the arm 101 preferably has the tooth 106 and a tooth 107. The tooth 107 is turned radially inwards, that is to say in the direction of the axis X7. Tooth 106 constitutes an obstacle that pin 81 must cross to allow knuckles 3 and 5 to pivot beyond orientation P3, towards sector S1 and orientation P1. In other words, pin 81 then comes into orthoradial abutment against tooth 106 for orientation P3. Conversely, tooth 106 constitutes an obstacle that pin 81 must cross to allow knuckles 3 and 5 to pivot to orientation P3, while the knuckles were in sector S1 or in orientation P1. Tooth 107 constitutes an obstacle that pin 81 must cross to allow knuckles 3 and 5 to pivot beyond orientation P3, towards sector S0 and orientation P2. In other words, the pin 81 then comes into orthoradial abutment against the tooth 107 for the orientation P3, so as to be captured between the teeth 106 and 107. Conversely, the tooth 107 constitutes an obstacle that the pin 81 must cross to authorize the knuckles 3 and 5 to pivot to orientation P3, while the knuckles were in orientation P2 or in sector S0. The crossing of the tooth 107 by the pin 81 is performed by elastic deformation of the arm 101, in an external radial direction, and advantageously of the blade 103, in an internal radial direction.

Lorsque les charnons 3 et 5 sont dans l'orientation P2, le bras 102 entoure le pion 81 de façon à l'accrocher, pour ainsi s'opposer au pivotement relatif des charnons 3 et 5 lorsqu'ils sont dans l'orientation P2. Pour cela, de préférence, le bras 102 présente avantageusement une dent 108. La dent 108 est tournée radialement vers l'intérieur. La dent 108 constitue un obstacle que le pion 81 doit franchir pour autoriser les charnons 3 et 5 à pivoter par-delà l'orientation P2, en direction du secteur S0, de l'orientation P3, du secteur S1 et de l'orientation P1. Autrement dit, le pion 81 vient alors en butée orthoradiale contre la dent 108 pour l'orientation P2. Réciproquement, la dent 108 constitue un obstacle que le pion 81 doit franchir pour autoriser les charnons 3 et 5 à pivoter jusqu'à l'orientation P2, alors que les charnons étaient dans l'orientation P1, dans le secteur S1, dans le secteur P3 ou dans le secteur S0. Le franchissement de la dent 108 par le pion 81 est effectué par déformation élastique du bras 102, suivant une direction radiale externe, et avantageusement de la lame 103, suivant une direction radiale interne.When the knuckles 3 and 5 are in the orientation P2, the arm 102 surrounds the pin 81 so as to hook it, thus opposing the relative pivoting of the knuckles 3 and 5 when they are in the orientation P2. For this, the arm 102 preferably has a tooth 108. The tooth 108 is turned radially inwards. Tooth 108 constitutes an obstacle that pin 81 must cross to allow knuckles 3 and 5 to pivot beyond orientation P2, towards sector S0, orientation P3, sector S1 and orientation P1 . In other words, pin 81 then comes into orthoradial abutment against tooth 108 for orientation P2. Conversely, tooth 108 constitutes an obstacle that pin 81 must cross to allow knuckles 3 and 5 to pivot to orientation P2, while the knuckles were in orientation P1, in sector S1, in sector P3 or in sector S0. The crossing of the tooth 108 by the pin 81 is performed by elastic deformation of the arm 102, in an external radial direction, and advantageously of the blade 103, in an internal radial direction.

Optionnellement, la partie centrale 100 du corps principal 65 présente une dent 109, qui est disposée en regard de la dent 108, la dent 109 est tournée radialement vers l'extérieur, c'est-à-dire à l'opposé de l'axe X7. Les dents 108 et 109 forment ainsi une pince qui borde l'ouïe 104. La dent 109 constitue un obstacle que le pion 81 doit franchir, en même temps que la dent 108, pour autoriser les charnons 3 et 5 à pivoter par-delà l'orientation P2, en direction du secteur S0, de l'orientation P3, du secteur S1 et de l'orientation P1. Autrement dit, le pion 81 vient alors en butée orthoradiale contre la dent 109 pour l'orientation P2. Réciproquement, la dent 109 constitue un obstacle que le pion 81 doit franchir pour autoriser les charnons 3 et 5 à pivoter jusqu'à l'orientation P2, alors que les charnons étaient dans l'orientation P1, dans le secteur S1, dans l'orientation P3 ou dans le secteur S0. Le franchissement de la dent 109 par le pion 81 est effectué par déformation élastique de la partie centrale 100, suivant une direction radiale interne. En particulier, c'est essentiellement la dent 109 qui est ainsi déformée.Optionally, the central part 100 of the main body 65 has a tooth 109, which is arranged opposite the tooth 108, the tooth 109 is turned radially outward, that is to say opposite the X7 axis. The teeth 108 and 109 thus form a clamp which borders the hearing 104. The tooth 109 constitutes an obstacle which the pin 81 must cross, at the same time as the tooth 108, to authorize the knuckles 3 and 5 to pivot beyond the orientation P2, towards sector S0, orientation P3, sector S1 and orientation P1. In other words, pin 81 then comes into orthoradial abutment against tooth 109 for orientation P2. Conversely, tooth 109 constitutes an obstacle that pin 81 must cross to allow knuckles 3 and 5 to pivot to orientation P2, while the knuckles were in orientation P1, in sector S1, in the orientation P3 or in sector S0. The crossing of the tooth 109 by the pin 81 is performed by elastic deformation of the central part 100, in an internal radial direction. In particular, it is essentially tooth 109 which is thus deformed.

Les bras 101 et 102 sont séparés l'un de l'autre par une encoche 105, ce qui permet la déformation élastique radiale susmentionnée des bras 101 et 102. L'encoche 105 est radialement traversante. Optionnellement, le pion 81 peut être introduit dans l'ouïe 104 via l'encoche 105. Lorsque les charnons 3 et 5 sont dans le secteur S0, le pion 81 est positionné dans une zone de l'ouïe 104 au sein de laquelle l'encoche 105 débouche, c'est-à-dire est positionné entre les deux bras 101 et 102. Ainsi, les bras 101 et 102 ne s'opposent pas au déplacement du pion 81, c'est-à-dire au pivotement relatif des charnons 3 et 5.The arms 101 and 102 are separated from each other by a notch 105, which allows the aforementioned radial elastic deformation of the arms 101 and 102. The notch 105 is radially through. Optionally, the pin 81 can be introduced into the hearing 104 via the notch 105. When the knuckles 3 and 5 are in the sector S0, the pin 81 is positioned in a zone of the hearing 104 within which the notch 105 opens out, that is to say is positioned between the two arms 101 and 102. Thus, the arms 101 and 102 do not oppose the movement of the pin 81, that is to say the relative pivoting of the knuckle 3 and 5.

Pour favoriser la déformation élastique radiale des bras 101 et 102, on peut prévoir que le corps principal 65 comprend, pour chaque bras 101 et 102, ou pour l'un des bras, une ouïe, qui traverse le corps 65 parallèlement à l'axe X7, et qui s'étend dans le bras 101 ou 102 concerné. Chaque ouïe sépare le bras concerné en deux, sur une partie de la longueur du bras concerné, et se présente sous la forme d'un orifice oblong et courbe, suivant la courbure du bras concerné. Ici, on prévoit une ouïe 110, qui appartient au bras 101 et une ouïe 111, qui appartient au bras 102.To promote the radial elastic deformation of the arms 101 and 102, provision may be made for the main body 65 to comprise, for each arm 101 and 102, or for one of the arms, a soundhole, which passes through the body 65 parallel to the axis X7, and which extends into the arm 101 or 102 concerned. Each soundhole separates the arm concerned in two, over part of the length of the arm concerned, and is in the form of an oblong and curved orifice, following the curvature of the arm concerned. Here, there is provided a hearing 110, which belongs to the arm 101 and a hearing 111, which belongs to the arm 102.

Structurellement, l'armature 66 se présente sous la forme d'un jonc ou d'une feuille métallique, au moins pour ce qui concerne la lame d'arrêt 103, qui joue le rôle d'un jonc-ressort ou d'une lame-ressort. Ici, l'armature 66 forme une feuille métallique, d'épaisseur sensiblement constante sur toute sa longueur, et dont la largeur est parallèle à l'axe X7, et donc à l'axe X81 du pion 81. La lame d'arrêt 103 est positionnée à l'intérieur de l'ouïe 104, préférentiellement le long de la partie centrale 100 et radialement en regard des bras 101 et 102.Structurally, the armature 66 is in the form of a rod or a metal sheet, at least as regards the stop blade 103, which plays the role of a spring rod or a blade -spring. Here, the armature 66 forms a metal sheet, of substantially constant thickness over its entire length, and the width of which is parallel to the axis X7, and therefore to the axis X81 of the pin 81. The stop blade 103 is positioned inside the hearing 104, preferably along the central part 100 and radially opposite the arms 101 and 102.

Comme montré en pointillés sur la figure 3 et en partie sur la figure 5, l'armature 66 comprend préférentiellement une ancre 112, et une ancre 113. Les ancres 112 et 113 constituent préférentiellement des extrémités opposées de l'armature 66. Les ancres 112 et 113 sont formées aux extrémités de la lame 103. Ici, chaque ancre 112 et 113 se présente sous la forme d'un crochet respectif, c'est-à-dire une partie recourbée de l'armature 66. Les ancres 112 et 113 sont accrochées, et même préférentiellement implantées, dans le corps principal 65, ce qui rend l'armature 66 solidaire du corps principal 65. Ici, l'ancre 112 est implantée dans le bras 101, par l'intermédiaire de l'ouïe 104. Ici, l'ancre 113 est implantée dans le bras 102, par l'intermédiaire de l'ouïe 104. Cette implantation des ancres 112 et 113 est préférentiellement obtenue par surmoulage du corps 65 sur l'armature 66. En variante, on prévoit une seule des deux ancres 112 et 113, ou aucune ancre, l'armature métallique étant alors solidaire du corps principal par un autre moyen.As shown in dotted lines on the picture 3 and partly on the figure 5 , the armature 66 preferably comprises an anchor 112, and an anchor 113. The anchors 112 and 113 preferably constitute opposite ends of the frame 66. The anchors 112 and 113 are formed at the ends of the blade 103. Here, each anchor 112 and 113 is in the form of a respective hook, that is to say a curved part of the armature 66. The anchors 112 and 113 are attached, and even preferentially implanted, in the main body 65, which makes the armature 66 integral with the main body 65. Here, the anchor 112 is implanted in the arm 101, through the hearing 104. Here, the anchor 113 is implanted in the arm 102, through the hearing 104. This implantation of the anchors 112 and 113 is preferably obtained by overmolding the body 65 on frame 66. Alternatively, only one of the two anchors 112 and 113 is provided, or no anchor, the metal frame then being integral with the main body by another means.

Comme bien visible sur la figure 4, le corps principal 65 forme une encoche 114, qui contribue à la solidarisation de l'armature 66 avec le corps principal 65. Ici, l'encoche 114 est ménagée dans la partie centrale 100 du corps principal, débouchant dans l'ouïe 104. Une partie de l'armature métallique 66, ici une partie de la lame d'arrêt 103, est reçue dans l'encoche 114, ce qui permet de fixer l'armature 66 par rapport au corps principal 65 suivant l'axe X7, tout en laissant la possibilité à l'armature 66 de se déformer. En particulier, l'encoche 114 est formée au travers de la dent 109, de sorte que la dent 109 est en saillie vers l'intérieur de l'ouïe 104 par rapport à la lame d'arrêt 103, pour pouvoir s'opposer au pivotement des charnons 3 et 5 par coopération mécanique avec le pion 81.As clearly visible on the figure 4 , the main body 65 forms a notch 114, which contributes to the attachment of the armature 66 to the main body 65. Here, the notch 114 is made in the central part 100 of the main body, opening into the hearing 104. A part of the metal reinforcement 66, here a part of the stop blade 103, is received in the notch 114, which makes it possible to fix the reinforcement 66 with respect to the main body 65 along the axis X7, while leaving the possibility for the armature 66 to deform. In particular, the notch 114 is formed through the tooth 109, so that the tooth 109 projects towards the inside of the hearing 104 with respect to the stop blade 103, in order to be able to oppose the pivoting of knuckles 3 and 5 by mechanical cooperation with pin 81.

Structurellement, de préférence, la lame d'arrêt 103 de l'armature 66 forme successivement une partie courbe 121, une dent 122, une dent 123, qui peut être qualifiée de « dent intermédiaire », une rampe 124, et une partie courbe 125. Comme illustré, ces différentes parties sont matérialisées par des courbures locales de la lame d'arrêt 103. La partie courbe 121 s'étend à partir de l'ancre 112. La partie courbe 125 s'étend à partir de l'ancre 113. De préférence, c'est une partie de la rampe 124 qui est reçues par l'encoche 114.Structurally, preferably, the stop blade 103 of the armature 66 successively forms a curved part 121, a tooth 122, a tooth 123, which can be described as an "intermediate tooth", a ramp 124, and a curved part 125 As illustrated, these different parts are materialized by local curvatures of the stop blade 103. The curved part 121 extends from the anchor 112. The curved part 125 extends from the anchor 113 Preferably, it is a part of the ramp 124 which is received by the notch 114.

Pour toute orientation relative des charnons 3 et 5, au moins une partie de la lame 103 est agencée entre le pion 81 et l'axe X7, en particulier entre le pion 81 et la partie centrale 100 du corps principal 65. Autrement dit, le pion 81 se trouve radialement interposé entre la lame 103 et le bras 101, ou entre la lame 103 et le bras 102.For any relative orientation of the knuckles 3 and 5, at least a part of the blade 103 is arranged between the pin 81 and the axis X7, in particular between the pin 81 and the central part 100 of the main body 65. In other words, the pin 81 is radially interposed between blade 103 and arm 101, or between blade 103 and arm 102.

Pour que l'organe d'arrêt 73 s'oppose ou autorise le pivotement relatif des charnons 3 et 5, on prévoit avantageusement qu'une coopération mécanique s'opère entre le pion 81 et la lame d'arrêt 103. C'est la position de chaque dent et rampe de la lame d'arrêt 103 qui détermine pour quelles orientations les charnons 3 et 5 sont autorisés ou empêchés de pivoter. En variante, en fonction des orientations que l'on souhaite indexer pour les charnons 3 et 5, on prévoit avantageusement que la lame d'arrêt présente un nombre de dents et de rampes différent de celui qui est illustré, et qui sont positionnées différemment.So that the stop member 73 opposes or authorizes the relative pivoting of the knuckles 3 and 5, provision is advantageously made for mechanical cooperation to take place between the pin 81 and the stop blade 103. This is the position of each tooth and ramp of the stop blade 103 which determines for which orientations the knuckles 3 and 5 are authorized or prevented from pivoting. As a variant, depending on the orientations that one wishes to index for the knuckles 3 and 5, it is advantageously provided that the stop blade has a number of teeth and ramps different from that which is illustrated, and which are positioned differently.

Les parties courbes 121 et 125 de la lame 103 sont disposées aux extrémités orthoradiales de l'ouïe 104 et servent ainsi de butées pour le pivotement des charnons 3 et 5, en accueillant le pion 81 en leur sein pour borner deux fins de courses opposées du pivotement relatif des charnons 3 et 5.The curved parts 121 and 125 of the blade 103 are arranged at the orthoradial ends of the hearing 104 and thus serve as stops for the pivoting of the knuckles 3 and 5, by accommodating the pin 81 within them to limit two opposite ends of the relative pivoting of knuckles 3 and 5.

En particulier, la partie courbe 121 constitue une butée, contre laquelle le pion 81 vient en butée orthoradiale lorsque les charnons 3 et 5 sont dans l'orientation P1, ce qui borne le pivotement des charnons 3 et 5 à l'orientation P1. Autrement dit, l'orientation P1 est une fin de course de pivotement des charnons 3 et 5 imposée par le dispositif 9. En particulier, la partie courbe 125 constitue une butée, contre laquelle le pion 81 vient en butée orthoradiale lorsque les charnons 3 et 5 sont dans l'orientation P2, ce qui borne le pivotement des charnons 3 et 5 à l'orientation P2. Autrement dit, l'orientation P2 est une fin de course de pivotement des charnons 3 et 5 imposée par le dispositif 9, opposée à la fin de course de l'orientation P1. Comme illustré sur la figure 3, chaque partie courbe 121 et 125 présente avantageusement une courbure qui épouse une paroi périphérique du pion 81, ici cylindrique à base circulaire centrée sur l'axe X81. Le fait de prévoir que l'armature 66 forme les butées de fin de course en pivotement des charnons 3 et 5, en armant les bras 101 et 102 s'ils sont prévus, assure une excellente durabilité du dispositif 9, dont l'organe d'arrêt 73 présente moins de chance d'être rompu si la porte du véhicule subit un effort qui tend à orienter les charnons 3 et 5 au-delà de la fin de course autorisée par le dispositif 9.In particular, the curved part 121 constitutes an abutment, against which the pin 81 comes into orthoradial abutment when the knuckles 3 and 5 are in the orientation P1, which limits the pivoting of the knuckles 3 and 5 to the orientation P1. In other words, the orientation P1 is an end of pivoting stroke of the knuckles 3 and 5 imposed by the device 9. In particular, the curved part 125 constitutes an abutment, against which the pin 81 comes into orthoradial abutment when the knuckles 3 and 5 are in the orientation P2, which limits the pivoting of the knuckles 3 and 5 to the orientation P2. In other words, the orientation P2 is an end of pivoting stroke of the knuckles 3 and 5 imposed by the device 9, opposite to the end of the stroke of the orientation P1. As illustrated on the picture 3 , each curved part 121 and 125 advantageously has a curvature which matches a peripheral wall of the pin 81, here cylindrical with a circular base centered on the axis X81. The fact of providing that the armature 66 forms the limit stops in pivoting of the knuckles 3 and 5, by arming the arms 101 and 102 if they are provided, ensures excellent durability of the device 9, of which the organ of stop 73 has less chance of being broken if the vehicle door undergoes a force which tends to orient the knuckles 3 and 5 beyond the end of travel authorized by the device 9.

En variante, chaque butée, ou l'une des butées, est assurée par seulement le bras 101 ou le bras 102 concerné, sans recours à l'armature 66.Alternatively, each stop, or one of the stops, is ensured by only the arm 101 or the arm 102 concerned, without recourse to the armature 66.

Dans le présent exemple, l'organe d'arrêt 73 met en oeuvre à la fois une coopération de la charnière 1 avec la lame d'arrêt 103 et avec le corps principal 65 pour indexer l'orientation des charnons 3 et 5, ce qui permet d'obtenir, par exemple, que l'organe d'arrêt 73 s'oppose davantage au pivotement des charnons 3 et 5 pour l'orientation P1 que pour l'orientation P2 ou vice-versa.In the present example, the stop member 73 implements both a cooperation of the hinge 1 with the stop blade 103 and with the main body 65 to index the orientation of the knuckles 3 and 5, which allows to obtain, for example, that the stop member 73 is more opposed to the pivoting of the knuckles 3 and 5 for the orientation P1 than for the orientation P2 or vice versa.

Comme visible sur la figure 3, la dent 122 est agencée pour s'opposer au pivotement des charnons 3 et 5 lorsque les charnons 3 et 5 sont dans l'orientation P1. Pour cela, de préférence, la dent 122 est tournée radialement vers l'extérieur, c'est-à-dire à l'opposé de l'axe X7, alors que la lame 103 borde le pion 81 radialement vers l'intérieur. Le pion 81 vient alors en butée orthoradiale contre la dent 122. La dent 122 constitue un obstacle que le pion 81 doit franchir pour autoriser les charnons 3 et 5 à pivoter par-delà l'orientation P1, en direction du secteur S1, de l'orientation P3, du secteur S0 et de l'orientation P2. Réciproquement, la dent 122 constitue un obstacle que le pion 81 doit franchir pour autoriser les charnons 3 et 5 à pivoter jusqu'à l'orientation P1, alors que les charnons étaient dans le secteur S1, l'orientation P3, dans le secteur S0 ou dans l'orientation P2. Le franchissement de la dent 122 par le pion 81 est effectué par déformation élastique de la lame 103, suivant une direction radiale interne. Dans la l'orientation P1, le pion 81 est donc capturé entre la partie courbe 121 et la dent 122. Le bas 101 étant disposé en regard d'une partie de la lame d'arrêt 103, le pion 81 est interposé entre ledit bras 101 et ladite lame 103 lorsque la charnière 1 est dans l'orientation P1. La dent 106 et la dent 122 sont disposées en face l'une de l'autre et contribuent ensemble à empêcher le pivotement de la charnière 1 hors de l'orientation P1.As seen on the picture 3 , the tooth 122 is arranged to oppose the pivoting of the knuckles 3 and 5 when the knuckles 3 and 5 are in the orientation P1. For this, tooth 122 is preferably turned radially outward, that is to say opposite axis X7, while blade 103 borders pin 81 radially inward. The pin 81 then comes into orthoradial abutment against the tooth 122. The tooth 122 constitutes an obstacle that the pin 81 must cross to allow the knuckles 3 and 5 to pivot beyond the orientation P1, in the direction of the sector S1, of the orientation P3, sector S0 and orientation P2. Conversely, tooth 122 constitutes an obstacle that pin 81 must cross to allow knuckles 3 and 5 to pivot to orientation P1, while the knuckles were in sector S1, orientation P3, in sector S0 or in orientation P2. The crossing of the tooth 122 by the pin 81 is performed by elastic deformation of the blade 103, in an internal radial direction. In the orientation P1, the pin 81 is therefore captured between the curved part 121 and the tooth 122. The bottom 101 being arranged opposite a part of the stop blade 103, the pin 81 is interposed between said arm 101 and said blade 103 when hinge 1 is in orientation P1. Tooth 106 and tooth 122 are arranged opposite each other and together contribute to preventing hinge 1 from pivoting out of orientation P1.

Les dents 122 et 123 sont agencées pour s'opposer au pivotement des charnons 3 et 5 lorsque les charnons 3 et 5 sont dans l'orientation P3. Pour cela, de préférence, la dent 123 est tournée radialement vers l'extérieur. Le pion 81 vient alors en butée orthoradiale contre la dent 123, de sorte à être capturé entre les dents 122 et 123. La dent 122 constitue un obstacle que le pion 81 doit franchir pour autoriser les charnons 3 et 5 à pivoter par-delà l'orientation P3, en direction du secteur S1 ou de l'orientation P1. Réciproquement, la dent 122 constitue un obstacle que le pion 81 doit franchir pour autoriser les charnons 3 et 5 à pivoter jusqu'à l'orientation P3, alors que les charnons 3 et 5 étaient dans l'orientation P1 ou dans le secteur S1. La dent 123 constitue un obstacle que le pion 81 doit franchir pour autoriser les charnons 3 et 5 à pivoter par-delà l'orientation P3, en direction du secteur S0 ou de l'orientation P2. Réciproquement, la dent 123 constitue un obstacle que le pion 81 doit franchir pour autoriser les charnons 3 et 5 à pivoter jusqu'à l'orientation P3, alors que les charnons 3 et 5 étaient dans le secteur S0 ou dans l'orientation P2. Le franchissement de la dent 123 par le pion 81 est effectué par déformation élastique de la lame 103, suivant une direction radiale interne. Le bas 101 étant disposé en regard d'une partie de la lame d'arrêt 103, le pion 81 est interposé entre ledit bras 101 et ladite lame 103 lorsque la charnière 1 est dans l'orientation P3. La dent 107 et la dent 123 sont disposées en face l'une de l'autre et contribuent ensemble à empêcher le pivotement de la charnière 1 hors de l'orientation P3.The teeth 122 and 123 are arranged to oppose the pivoting of the knuckles 3 and 5 when the knuckles 3 and 5 are in the orientation P3. For this, tooth 123 is preferably turned radially outwards. Pin 81 then comes into orthoradial abutment against tooth 123, so as to be captured between teeth 122 and 123. Tooth 122 constitutes an obstacle that pin 81 must cross to allow knuckles 3 and 5 to pivot beyond the orientation P3, in the direction of sector S1 or orientation P1. Conversely, tooth 122 constitutes an obstacle that pin 81 must cross to allow knuckles 3 and 5 to pivot to orientation P3, while knuckles 3 and 5 were in orientation P1 or in sector S1. Tooth 123 constitutes an obstacle that pin 81 must cross to allow knuckles 3 and 5 to pivot beyond orientation P3, towards sector S0 or orientation P2. Conversely, tooth 123 constitutes an obstacle that pin 81 must cross to allow knuckles 3 and 5 to pivot to orientation P3, while knuckles 3 and 5 were in sector S0 or in orientation P2. The crossing of the tooth 123 by the pin 81 is performed by elastic deformation of the blade 103, in an internal radial direction. The bottom 101 being arranged opposite a part of the stop blade 103, the pin 81 is interposed between said arm 101 and said blade 103 when the hinge 1 is in the orientation P3. Tooth 107 and tooth 123 are arranged opposite each other and together contribute to preventing hinge 1 from pivoting out of orientation P3.

De préférence, la courbe 125 de la lame 103, qui est rattachée à l'ancre 113, s'oppose au pivotement des charnons 3 et 5 lorsque les charnons 3 et 5 sont dans l'orientation P2. Pour cela, de préférence, l'extrémité de la lame 103 est recourbée de sorte à entourer le pion 81 sur plus de la moitié de sa circonférence, à la manière d'une pince, lorsque le pion 81 est dans la position P2. L'extrémité de la lame 103, au niveau de l'ancre 113 est un obstacle que le pion 81 doit franchir pour autoriser les charnons 3 et 5 à pivoter par-delà l'orientation P2, en direction des autres orientations P1 et P3. Réciproquement, cette extrémité de la lame 103 constitue un obstacle que le pion 81 doit franchir pour autoriser les charnons 3 et 5 à pivoter jusqu'à l'orientation P2. Le franchissement l'extrémité de la lame 103 par le pion 81 est effectué par déformation élastique de la lame 103 suivant une direction radiale externe, outre l'éventuelle déformation du bras 102. Dans le présent exemple, la dent 108 et la dent 109 disposées l'une en face de l'autre, ainsi que la courbe 125, contribuent ensemble à empêcher le pivotement de la charnière 1 hors de l'orientation P2.Preferably, the curve 125 of the blade 103, which is attached to the anchor 113, opposes the pivoting of the knuckles 3 and 5 when the knuckles 3 and 5 are in the orientation P2. For this, preferably, the end of blade 103 is curved so as to surround pin 81 over more than half of its circumference, like a clamp, when pin 81 is in position P2. The end of the blade 103, at the level of the anchor 113 is an obstacle that the pin 81 must cross to allow the knuckles 3 and 5 to pivot beyond the orientation P2, in the direction of the other orientations P1 and P3. Conversely, this end of the blade 103 constitutes an obstacle that the pin 81 must cross to allow knuckles 3 and 5 to pivot to orientation P2. The crossing of the end of the blade 103 by the pin 81 is carried out by elastic deformation of the blade 103 in an external radial direction, in addition to the possible deformation of the arm 102. In the present example, the tooth 108 and the tooth 109 arranged one opposite the other, as well as the curve 125, together contribute to preventing the pivoting of the hinge 1 out of the orientation P2.

De préférence, la dent 123 est plus saillante que la dent 122, et/ou la dent 107 est plus saillante que la dent 106, de sorte que le franchissement des dents 123 et 107 par le pion 81 est plus difficile que celui des dents 122 et 106.Preferably, the tooth 123 is more prominent than the tooth 122, and/or the tooth 107 is more prominent than the tooth 106, so that the crossing of the teeth 123 and 107 by the pin 81 is more difficult than that of the teeth 122 and 106.

Lorsque les charnons 3 et 5 sont dans le secteur S0, le pion 81 coulisse le long de la rampe 124, de sorte que le pivotement des charnons 3 et 5 est autorisé pour le secteur S0. On peut optionnellement prévoir que, lorsque les charnons 3 et 5 sont orientés dans le secteur S0, le pion 81 déforme radialement vers l'intérieur, c'est-à-dire vers l'axe X7, l'armature 66 par l'intermédiaire de la rampe 124, de sorte que le pivotement des charnons est amorti par frottement du pion 81 contre la rampe 124. De préférence, le secteur S0 correspond à une orientation stable pour les charnons 3 et 5, le dispositif 9 ne tendant pas particulièrement à ramener les charnons 3 et 5 dans l'une des orientations P2 ou P3 lorsque les charnons 3 et 5 sont orientés dans le secteur S0. En variante, on prévoit que le secteur S0 correspond à une orientation instable pour les charnons 3 et 5, pour tendre à ramener les charnons dans soit dans l'orientation P2 soit dans l'orientation P3 sous l'action de la lame 103 et/ou du bras 102 lorsque les charnons sont dans le secteur S0.When the knuckles 3 and 5 are in the sector S0, the pin 81 slides along the ramp 124, so that the pivoting of the knuckles 3 and 5 is authorized for the sector S0. One can optionally provide that, when the knuckles 3 and 5 are oriented in the sector S0, the pin 81 deforms radially inwards, that is to say towards the axis X7, the armature 66 via of the ramp 124, so that the pivoting of the knuckles is damped by friction of the pin 81 against the ramp 124. Preferably, the sector S0 corresponds to a stable orientation for the knuckles 3 and 5, the device 9 not particularly tending to bring the knuckles 3 and 5 into one of the orientations P2 or P3 when the knuckles 3 and 5 are oriented in the sector S0. Alternatively, provision is made for the sector S0 to correspond to an unstable orientation for the knuckles 3 and 5, to tend to bring the knuckles into either the orientation P2 or the orientation P3 under the action of the blade 103 and/ or arm 102 when the knuckles are in sector S0.

Lorsque les charnons 3 et 5 sont dans le secteur S1, le pion 81 coulisse contre la dent 122 et/ou la dent 106, de sorte que le pivotement des charnons 3 et 5 est autorisé pour le secteur S1. Lorsque les charnons 3 et 5 sont orientés dans le secteur S1, le pion 81 déforme l'armature 66 radialement vers l'intérieur par l'intermédiaire de la dent 122. Le pion 81 étant au sommet de la dent 122, le secteur S1 correspond à une orientation instable pour les charnons 3 et 5, qui tendent à être ramenés soit dans l'orientation P1 soit dans l'orientation P3 sous l'action des dents 122 et/ou 106.When knuckles 3 and 5 are in sector S1, pin 81 slides against tooth 122 and/or tooth 106, so that pivoting of knuckles 3 and 5 is authorized for sector S1. When knuckles 3 and 5 are oriented in sector S1, pin 81 deforms armature 66 radially inwards via tooth 122. Pin 81 being at the top of tooth 122, sector S1 corresponds to an unstable orientation for the knuckles 3 and 5, which tend to be returned either to the orientation P1 or to the orientation P3 under the action of the teeth 122 and/or 106.

On peut prévoir que les caractéristiques qui sont décrites pour la position P2 s'appliquent à la position P1 et vice-versa, en particulier en ce qui concerne les caractéristiques de la lame 103 et des bras 101 et 102.Provision can be made for the characteristics which are described for position P2 to apply to position P1 and vice versa, in particular as regards the characteristics of the blade 103 and of the arms 101 and 102.

La figure 8 montre un dispositif d'arrêt 209 selon un deuxième mode de réalisation conforme à l'invention. Le dispositif d'arrêt 209 est identique au dispositif d'arrêt 9 et s'utilise de la même façon, sauf pour les différences visibles sur la figure 8 et décrites ci-dessous. Les caractéristiques du mode de réalisation de la figure 8, qui sont similaires ou correspondantes à celles du mode réalisation des figures 1 à 7 portent le même signe de référence augmenté de 200.There figure 8 shows a stop device 209 according to a second embodiment in accordance with the invention. The stop device 209 is identical to the stop device 9 and is used in the same way, except for the differences visible on the figure 8 and described below. The characteristics of the embodiment of the figure 8 , which are similar or corresponding to those of the embodiment of the figures 1 to 7 bear the same reference sign increased by 200.

Le dispositif 209 est conçu pour être monté sur la charnière 1 décrite ci-avant, incluant le charnon 3, le charnon 5, l'arbre 7 et notamment le pion 81. Sur la figure 8, on montre comment le dispositif d'arrêt 209 est montré sur l'arbre 7 et coopère avec le pion 81, l'arbre 7 et le pion 81 étant montrés en pointillés.The device 209 is designed to be mounted on the hinge 1 described above, including the knuckle 3, the knuckle 5, the shaft 7 and in particular the pin 81. On the figure 8 , it is shown how the stop device 209 is shown on the shaft 7 and cooperates with the pin 81, the shaft 7 and the pin 81 being shown in dotted lines.

Structurellement, le dispositif d'arrêt 209 est constitué par un corps principal 265 et par une armature métallique 266, qui sont solidaires, c'est-à-dire attachés l'un à l'autre.Structurally, the stop device 209 is constituted by a main body 265 and by a metal reinforcement 266, which are integral, that is to say attached to one another.

Le corps principal 265 est préférentiellement formé d'un seul tenant, dans un unique matériau exempt de matière métallique. Par exemple, le corps principal 265 est réalisé en matière plastique polymère, de préférence un polyamide tel qu'un polyamide 6.6. En variante, le corps principal 265 est réalisé en matériau composite, comprenant une matrice en matière plastique polymère, de préférence un polyamide tel qu'un polyamide 6.6, et un renfort, par exemple des fibres de verre, qui sont noyées dans la matrice.The main body 265 is preferably formed in one piece, in a single material free of metallic material. For example, the main body 265 is made of polymeric plastic material, preferably a polyamide such as a polyamide 6.6. As a variant, the main body 265 is made of a composite material, comprising a polymer plastic matrix, preferably a polyamide such as a polyamide 6.6, and a reinforcement, for example glass fibers, which are embedded in the matrix.

Au contraire, l'armature métallique 266 est réalisée en métal, tel qu'un acier inoxydable.On the contrary, the metal frame 266 is made of metal, such as stainless steel.

Pour la fabrication du dispositif d'arrêt 209, on prévoit avantageusement que le corps principal 265 est surmoulé sur l'armature métallique 266, formée au préalable, ce qui facilite la fabrication tout en assurant une solidarité fiable du corps 265 avec l'armature 266. Alternativement, le corps principal 265 et l'armature métallique 266 sont fabriqués séparément puis assemblés, par exemple par clipsage de l'armature 266 sur le corps 265.For the manufacture of the stop device 209, provision is advantageously made for the main body 265 to be overmolded on the metal frame 266, formed beforehand, which facilitates manufacture while ensuring reliable solidarity of the body 265 with the frame 266 Alternatively, the main body 265 and the metal frame 266 are manufactured separately and then assembled, for example by clipping the frame 266 onto the body 265.

L'armature métallique 266 vise à conférer au dispositif 209 une résistance structurelle élevée en l'armant, alors que le corps principal 265, qui constitue l'essentiel du volume du dispositif 209, fait que le dispositif 209 est globalement peu sensible au dépôt de particules indésirables lors du peinturage.The metal frame 266 aims to give the device 209 a high structural strength by arming it, while the main body 265, which constitutes the bulk of the volume of the device 209, makes the device 209 globally insensitive to the deposition of unwanted particles when painting.

Fonctionnellement, le dispositif d'arrêt 209 comprend un orifice 267 et un organe d'arrêt 273, et une surface antirotation 271. L'orifice 267 et la surface antirotation 271 sont avantageusement entièrement formés par le corps principal 265, alors que l'organe d'arrêt 273 est avantageusement formé en partie par le corps principal 265 et en partie par l'armature métallique 266.Functionally, the stop device 209 comprises an orifice 267 and a stop member 273, and an anti-rotation surface 271. The orifice 267 and the anti-rotation surface 271 are advantageously entirely formed by the main body 265, whereas the member stopper 273 is advantageously formed partly by the main body 265 and partly by the metal reinforcement 266.

Le corps principal 265 comporte une partie centrale 300, qui présente deux flancs opposés et parallèles, dont le flanc 272 visible sur la figure 8. Ces flancs sont perpendiculaires à l'axe X7. L'orifice 267 traverse le corps principal 265 de part en part, en particulier la partie centrale 300, en étant coaxialement traversé par l'axe X7. L'orifice 267 est donc entièrement formé par le corps principal 265. l'orifice 267. L'orifice 267 débouche des deux flancs du corps 265. L'orifice 267 est configuré pour être enfilé sur l'arbre 7. Ainsi monté sur l'arbre 7, le dispositif d'arrêt 209 et le charnon 3 sont pivotants l'un par rapport à l'autre autour de l'axe X7.The main body 265 comprises a central part 300, which has two opposite and parallel sides, of which the side 272 visible on the figure 8 . These flanks are perpendicular to the axis X7. The orifice 267 crosses the main body 265 right through, in particular the central part 300, being coaxially crossed by the axis X7. The orifice 267 is therefore entirely formed by the main body 265. the orifice 267. The orifice 267 emerges from the two sides of the body 265. The orifice 267 is configured to be threaded onto the shaft 7. Thus mounted on the shaft 7, the stop device 209 and the knuckle 3 are pivotable with respect to each other around the axis X7.

En particulier, l'orifice 267 du dispositif 209 est monté sur une partie intermédiaire 69 appartenant à l'arbre 7, de la même façon qu'illustré sur la figure 3 pour le dispositif 9. L'orifice 267 est avantageusement monté serré sur l'arbre 7, ici par l'intermédiaire de la partie 69, de sorte que le dispositif 209 est fixé axialement par rapport à la charnière 1, c'est-à-dire est empêché de translater suivant l'axe X7. Pour que le montage serré soit suffisant pour maintenir le dispositif 209 solidaire de l'arbre 7, tout en permettant son démontage de l'arbre 7 une fois les étapes de fabrication du véhicule effectuées, l'orifice 267 présente avantageusement des cannelures internes. Les cannelures permettent avantageusement de prévoir que l'arbre 7 et le dispositif 209 sont d'abord retirés d'un bloc de la charnière 1, puisque l'arbre 7 et le dispositif 209 sont désolidarisés pour une utilisation ultérieure. Alternativement, les cannelures peuvent permettre de prévoir que l'arbre 7 et le dispositif 209 restent solidaires, et sont montés sur, et retirés de, la charnière 1 d'un seul bloc.In particular, the orifice 267 of the device 209 is mounted on an intermediate part 69 belonging to the shaft 7, in the same way as illustrated in the picture 3 for the device 9. The orifice 267 is advantageously mounted tight on the shaft 7, here via the intermediary of the part 69, so that the device 209 is fixed axially with respect to the hinge 1, i.e. -say is prevented from translating along the X7 axis. For the tight assembly to be sufficient to hold the device 209 secured to the shaft 7, while allowing it to be dismantled from the shaft 7 once the vehicle manufacturing steps have been carried out, the orifice 267 advantageously has internal splines. The splines advantageously make it possible to provide that the shaft 7 and the device 209 are first withdrawn from a block of the hinge 1, since the shaft 7 and the device 209 are separated for later use. Alternatively, the splines can make it possible to provide that the shaft 7 and the device 209 remain integral, and are mounted on, and removed from, the hinge 1 in a single block.

Lorsque le dispositif 209 est monté sur l'arbre 7, le dispositif 209 est axialement interposé entre la tête 25 de l'arbre 7 et la branche 29 du charnon 5. En particulier, le dispositif 209 vient en appui contre le charnon 5 via le flanc 272, qui est tourné en direction des charnons 3 et 5 et qui s'appuie axialement contre la branche 29. Dans la direction opposée, le dispositif 9 vient en appui contre la tête 25 via le flanc opposé, en particulier contre un épaulement formé par la tête 25. Le dispositif 209 est ainsi fixé suivant l'axe X7 par rapport au charnon 5 et à l'arbre 7.When the device 209 is mounted on the shaft 7, the device 209 is axially interposed between the head 25 of the shaft 7 and the branch 29 of the knuckle 5. In particular, the device 209 bears against the knuckle 5 via the flank 272, which is turned in the direction of the knuckles 3 and 5 and which bears axially against the branch 29. In the opposite direction, the device 9 comes to bear against the head 25 via the opposite flank, in particular against a shoulder formed by the head 25. The device 209 is thus fixed along the axis X7 with respect to the knuckle 5 and to the shaft 7.

Comme visible sur la figure 8, la surface antirotation 271 du dispositif 209 est par exemple formée sur le flanc 272, plus généralement sur la partie centrale 300 du corps principal 265. La surface 271 est donc entièrement formée par le corps 265. La surface antirotation 271 se présente ici sous la forme d'une empreinte, qui est formée en creux sur le flanc 272. La surface antirotation 271 reçoit en son sein la branche 29 du charnon 5, de la même façon qu'illustré sur la figure 6 pour le dispositif 9. La surface antirotation 271 coopère mécaniquement avec la branche 29 du charnon 5 pour empêcher une rotation du charnon 5 et du dispositif 209 l'un par rapport à l'autre autour de l'axe X7. Autrement dit, la branche 29 et la surface antirotation 271 ont une forme complémentaire. Ainsi, lorsque le charnon 5 est pivoté par rapport au charnon 3, le dispositif d'arrêt 209 décrit le même mouvement que le charnon 5 autour de l'axe X7. La surface antirotation 271 et le la branche 29 sont configurés pour que la rotation relative du dispositif 209 et du charnon 5 soit bloquée dans les deux sens autour de l'axe X7.As seen on the figure 8 , the anti-rotation surface 271 of the device 209 is for example formed on the flank 272, more generally on the central part 300 of the main body 265. The surface 271 is therefore entirely formed by the body 265. The anti-rotation surface 271 is presented here under the form of an indentation, which is formed hollow on the side 272. The anti-rotation surface 271 receives within it the branch 29 of the knuckle 5, in the same way as illustrated on the figure 6 for device 9. Anti-rotation surface 271 cooperates mechanically with branch 29 of knuckle 5 to prevent rotation of knuckle 5 and device 209 with respect to each other around axis X7. In other words, branch 29 and anti-rotation surface 271 have a complementary shape. Thus, when the knuckle 5 is pivoted with respect to the knuckle 3, the stop device 209 describes the same movement as the knuckle 5 around the axis X7. The anti-rotation surface 271 and the branch 29 are configured so that the relative rotation of the device 209 and the knuckle 5 is blocked in both directions around the axis X7.

En résumé, le dispositif 209 peut être monté sur la charnière, par enfilement de l'arbre 7 dans l'orifice 267, et par coopération antirotation entre le charnon 5 et la surface antirotation 271, de sorte que le dispositif 209 est fixe par rapport au charnon 5, ou pour le moins fixé en rotation par rapport au charnon 5 autour de l'axe X7.In summary, the device 209 can be mounted on the hinge, by threading the shaft 7 into the orifice 267, and by anti-rotation cooperation between the knuckle 5 and the anti-rotation surface 271, so that the device 209 is fixed relative to the knuckle 5, or at least fixed in rotation with respect to the knuckle 5 around the axis X7.

L'organe d'arrêt 273 est formé à la fois par une partie du corps principal 265, à savoir de préférence un bras 302 appartenant au corps principal 265, et par une partie de l'armature 266, à savoir une lame d'arrêt 303 appartenant à l'armature 266. Contrairement au dispositif 9, le dispositif 209 dispose d'un seul bras, à savoir le bras 302. Grâce à cette structure renforcée par l'armature 266, l'organe d'arrêt 273, particulièrement sollicité durant l'utilisation du dispositif d'arrêt 209, est fiable et structurellement endurant.The stop member 273 is formed both by a part of the main body 265, namely preferably an arm 302 belonging to the main body 265, and by a part of the frame 266, namely a stop blade 303 belonging to the armature 266. Unlike the device 9, the device 209 has a single arm, namely the arm 302. Thanks to this structure reinforced by the armature 266, the stop member 273, particularly stressed during the use of the stop device 209, is reliable and structurally enduring.

Lorsque le dispositif 209 est monté sur la charnière 1, l'organe d'arrêt 273 est configuré pour s'opposer au pivotement des charnons 3 et 5 l'un par rapport à l'autre, seulement lorsque les charnons sont positionnés dans l'orientation P2. En d'autres termes, l'organe d'arrêt 273 fonctionne comme un organe d'indexation pour indexer l'orientation des charnons 3 et 5 à l'orientation P2.When the device 209 is mounted on the hinge 1, the stop member 273 is configured to oppose the pivoting of the knuckles 3 and 5 relative to each other, only when the knuckles are positioned in the orientation P2. In other words, the stop member 273 functions as an indexing member to index the orientation of the knuckles 3 and 5 to the orientation P2.

Lorsque l'organe d'arrêt 273 s'oppose au pivotement relatif des charnons 3 et 5, il maintient la charnière dans l'orientation P2. Dans cette situation, la porte du véhicule est donc maintenue par le dispositif d'arrêt 9 dans l'orientation d'ouverture P2. Ainsi, de préférence, on ne peut pivoter les charnons 3 et 5 l'un par rapport à l'autre qu'en appliquant un effort suffisamment important sur la porte, pour vaincre le maintien opéré par le dispositif 209. Plus précisément, de préférence, en s'opposant ainsi à un pivotement relatif des charnons, l'organe d'arrêt 73 applique un couple de maintien sur le charnon 3, par rapport au charnon 5, autour de l'axe X7, qui peut être vaincu en appliquant un couple supérieur à ce couple de maintien sur les charnons 3 et 5, pour entraîner tout de même un pivotement des charnons 3 et 5 l'un par rapport à l'autre, hors de l'orientation P2 dans laquelle les charnons 3 et 5 étaient maintenus par le dispositif 209. Dans cette situation, l'organe d'arrêt 273 se déforme élastiquement, de sorte que le dispositif 209 n'est pas détérioré et peut ensuite à nouveau s'opposer au pivotement des charnons 3 et 5 lorsque les charnons atteignent à nouveau l'orientation P2.When the stop member 273 opposes the relative pivoting of the knuckles 3 and 5, it maintains the hinge in the orientation P2. In this situation, the vehicle door is therefore held by the stop device 9 in the opening orientation P2. Thus, preferably, the knuckles 3 and 5 can only be pivoted relative to each other by applying a sufficiently large force to the door, to overcome the holding effected by the device 209. More precisely, preferably , thus opposing a relative pivoting of the knuckle, the stop member 73 applies a holding torque on the knuckle 3, with respect to the knuckle 5, around the axis X7, which can be overcome by applying a torque greater than this holding torque on the knuckles 3 and 5, to cause all the same a pivoting of the knuckles 3 and 5 relative to each other, out of the orientation P2 in which the knuckles 3 and 5 were maintained by the device 209. In this situation, the stop member 273 deforms elastically, so that the device 209 is not damaged and can then again oppose the pivoting of the knuckles 3 and 5 when the knuckles again reach orientation P2.

Lorsque le dispositif 209 est monté sur la charnière 1, l'organe d'arrêt 273 est configuré pour autoriser le pivotement des charnons 3 et 5 l'un par rapport à l'autre autour de l'arbre 7, lorsque les charnons 3 et 5 sont positionnés l'un par rapport à l'autre dans toute autre orientation, incluant notamment le secteur angulaire de libération S0. Par « autoriser le pivotement des charnons », on entend que l'organe d'arrêt 273 ne s'oppose pas au pivotement des charnons 3 et 5, c'est-à-dire les laisse libre de pivoter, ou pour le moins ne s'oppose à leur pivotement que de manière marginale, comparativement au cas où les charnons sont dans l'orientation P2.When the device 209 is mounted on the hinge 1, the stop member 273 is configured to allow the pivoting of the knuckles 3 and 5 relative to each other around the shaft 7, when the knuckles 3 and 5 are positioned relative to each other in any other orientation, including in particular the angular sector of release S0. By "authorize the pivoting of the knuckles", it is meant that the stop member 273 does not oppose the pivoting of the knuckles 3 and 5, that is to say leaves them free to pivot, or for the less opposes their pivoting only marginally, compared to the case where the knuckles are in the orientation P2.

Pour s'opposer au pivotement des charnons 3 et 5, l'organe d'arrêt 273 coopère mécaniquement avec le pion 81 porté par le charnon 3, par exemple en le pinçant. Pour autoriser le pivotement, l'organe d'arrêt 273 libère le pion 81, notamment en coulissant contre le pion 81. Autrement dit, c'est par l'intermédiaire du pion 81 que l'organe d'arrêt 273 retient les charnons dans leur orientation P2, ou libère le pivotement des charnons pour les autres orientations.To oppose the pivoting of the knuckle 3 and 5, the stop member 273 cooperates mechanically with the pin 81 carried by the knuckle 3, for example by pinching it. To authorize pivoting, the stopper 273 releases the pin 81, in particular by sliding against the pin 81. In other words, it is via the pin 81 that the stopper 273 retains the knuckles in their orientation P2, or frees the pivoting of the knuckles for the other orientations.

Structurellement, le corps principal 265 définit un canal 304 en forme de crochet, pour la circulation du pion 81 lors du pivotement des charnons 3 et 5. Le canal 304 est de forme oblongue et courbe. Le canal 304 est en forme d'arc de cercle autour de l'axe X7. Le canal 304 est délimité, radialement sur l'intérieur, par la partie centrale 300 du corps principal 265, et, radialement sur l'extérieur, par le bras 302.Structurally, the main body 265 defines a channel 304 in the form of a hook, for the circulation of the pin 81 during the pivoting of the knuckles 3 and 5. The channel 304 is oblong and curved. The channel 304 is in the form of an arc of a circle around the axis X7. The channel 304 is delimited, radially on the inside, by the central part 300 of the main body 265, and, radially on the outside, by the arm 302.

Pour que l'organe d'arrêt 273 s'oppose ou autorise le pivotement des charnons 3 et 5, on prévoit avantageusement qu'une coopération mécanique s'opère entre le pion 81 et le corps principal 265, à savoir entre le pion 81 et le canal 304, notamment via le bras 302.So that the stop member 273 opposes or authorizes the pivoting of the knuckles 3 and 5, provision is advantageously made for mechanical cooperation to take place between the pin 81 and the main body 265, namely between the pin 81 and the channel 304, in particular via the arm 302.

Le bras 302 est fixement attaché à la partie centrale 300 de façon radiale par rapport à l'axe X7, en étant venu de matière avec la partie centrale 300. Le bras 302 est recourbé, suivant un plan orthogonal à l'axe X7. Le bras 302 entoure l'extrémité du canal 304, pour la délimiter.The arm 302 is fixedly attached to the central part 300 radially with respect to the axis X7, being integral with the central part 300. The arm 302 is curved, along a plane orthogonal to the axis X7. The arm 302 surrounds the end of the channel 304, to delimit it.

Comme montré sur la figure 8, lorsque les charnons 3 et 5 sont dans l'orientation P2, le bras 302 entoure le pion 81 de façon à l'accrocher, pour ainsi s'opposer au pivotement relatif des charnons 3 et 5 lorsqu'ils sont dans l'orientation P2. Pour cela, de préférence, le bras 302 présente avantageusement une dent 308. La dent 308 est tournée radialement vers l'intérieur. La dent 308 constitue un obstacle que le pion 81 doit franchir pour autoriser les charnons 3 et 5 à pivoter par-delà l'orientation P2, en direction notamment du secteur S0 et de l'orientation P1. Autrement dit, le pion 81 vient alors en butée orthoradiale contre la dent 308 pour l'orientation P2. Réciproquement, la dent 308 constitue un obstacle que le pion 81 doit franchir pour autoriser les charnons 3 et 5 à pivoter jusqu'à l'orientation P2, alors que les charnons étaient, notamment, dans l'orientation P1 ou dans le secteur S0. Le franchissement de la dent 308 par le pion 81 est effectué par déformation élastique du bras 302.As shown on the figure 8 , when the knuckles 3 and 5 are in the orientation P2, the arm 302 surrounds the pin 81 so as to hook it, thus opposing the relative pivoting of the knuckles 3 and 5 when they are in the orientation P2 . For this, the arm 302 preferably has a tooth 308. The tooth 308 is turned radially inwards. The tooth 308 constitutes an obstacle that the pin 81 must cross to authorize the knuckles 3 and 5 to pivot beyond the orientation P2, in the direction in particular of the sector S0 and of the orientation P1. In other words, pin 81 then comes into orthoradial abutment against tooth 308 for orientation P2. Conversely, the tooth 308 constitutes an obstacle that the pin 81 must cross to allow the knuckles 3 and 5 to pivot to the orientation P2, whereas the knuckles were, in particular, in the orientation P1 or in the sector S0. The crossing of the tooth 308 by the pin 81 is carried out by elastic deformation of the arm 302.

Optionnellement, la partie centrale 300 du corps principal 265 présente une dent 309, qui est disposée en regard de la dent 308, si la dent 308 est prévue. La dent 309 est tournée radialement vers l'extérieur, c'est-à-dire à l'opposé de l'axe X7. Les dents 308 et 309 forment ainsi une pince qui borde le canal 304. La dent 309 constitue un obstacle que le pion 81 doit franchir, en même temps que la dent 308, pour autoriser les charnons 3 et 5 à pivoter par-delà l'orientation P2, notamment en direction du secteur S1 et de l'orientation P1. Autrement dit, le pion 81 vient alors en butée orthoradiale contre la dent 309 pour l'orientation P2. Réciproquement, la dent 309 constitue un obstacle que le pion 81 doit franchir pour autoriser les charnons 3 et 5 à pivoter jusqu'à l'orientation P2, alors que les charnons étaient notamment dans l'orientation P1 ou dans le secteur S0. Le franchissement de la dent 309 par le pion 81 est effectué par déformation élastique de la partie centrale 300, suivant une direction radiale interne. En particulier, c'est essentiellement la dent 309 qui est ainsi déformée.Optionally, the central part 300 of the main body 265 has a tooth 309, which is arranged opposite the tooth 308, if the tooth 308 is provided. Tooth 309 faces radially outwards, that is to say opposite axis X7. The teeth 308 and 309 thus form a clamp which borders the channel 304. The tooth 309 constitutes an obstacle that the pin 81 must cross, at the same time as the tooth 308, to authorize the knuckles 3 and 5 to pivot beyond the orientation P2, in particular in the direction of the sector S1 and the orientation P1. In other words, pin 81 then comes into orthoradial abutment against tooth 309 for orientation P2. Conversely, tooth 309 constitutes an obstacle that pin 81 must cross to allow knuckles 3 and 5 to pivot to orientation P2, whereas the knuckles were in particular in orientation P1 or in sector S0. The crossing of the tooth 309 by the pin 81 is carried out by elastic deformation of the central part 300, in an internal radial direction. In particular, it is essentially tooth 309 which is thus deformed.

Lorsque les charnons 3 et 5 sont hors de l'orientation P2, c'est-à-dire notamment dans le secteur S0 ou la position P1, le pion 81 est positionné hors du canal 304. Ainsi, hors de l'orientation P2, le bras 302 ne s'oppose pas au déplacement du pion 81, c'est-à-dire au pivotement relatif des charnons 3 et 5.When the knuckles 3 and 5 are outside the orientation P2, that is to say in particular in the sector S0 or the position P1, the pin 81 is positioned outside the channel 304. Thus, outside the orientation P2, the arm 302 does not oppose the movement of the pin 81, that is to say the relative pivoting of the knuckles 3 and 5.

De préférence, lorsque les charnons 3 et 5 sont dans le secteur S0, le pion 81 coulisse le long d'une rampe 335 formée par la partie centrale 300, de sorte que le pivotement des charnons 3 et 5 est autorisé pour le secteur S0. Cela s'applique également au secteur S1 et aux orientations P1 et P3. On peut optionnellement prévoir que, lorsque les charnons 3 et 5 sont orientés dans le secteur S0, le pion 81 déforme radialement vers l'intérieur, c'est-à-dire vers l'axe X7, la partie centrale 300, par l'intermédiaire de la rampe 335, de sorte que le pivotement des charnons est amorti par frottement du pion 81 contre la rampe 335.Preferably, when the knuckles 3 and 5 are in the sector S0, the pin 81 slides along a ramp 335 formed by the central part 300, so that the pivoting of the knuckles 3 and 5 is authorized for the sector S0. This also applies to sector S1 and orientations P1 and P3. It is optionally possible to provide that, when the knuckles 3 and 5 are oriented in the sector S0, the pin 81 deforms radially inwards, that is to say towards the axis X7, the central part 300, by the intermediary of the ramp 335, so that the pivoting of the knuckles is damped by friction of the pin 81 against the ramp 335.

On peut optionnellement prévoir que le bras 302 présente une ouïe, non représentée, similaire à l'ouïe 111, pour faciliter sa déformation.One can optionally provide that the arm 302 has a hearing, not shown, similar to the hearing 111, to facilitate its deformation.

Structurellement, l'armature 266 se présente sous la forme d'un jonc ou d'une feuille métallique, au moins pour ce qui concerne la lame d'arrêt 303, qui joue le rôle d'un jonc-ressort ou d'une lame-ressort. Ici, l'armature 266 forme une feuille métallique, d'épaisseur sensiblement constante sur toute sa longueur, et dont la largeur est parallèle à l'axe X7, et donc à l'axe X81 du pion 81. La lame d'arrêt 303 s'étend le long de la partie centrale 300, et une partie de la lame 303 est positionnée à l'intérieur du canal 304, en regard du bras 302.Structurally, the armature 266 is in the form of a rod or a metal sheet, at least as regards the stop blade 303, which plays the role of a spring rod or a blade -spring. Here, the armature 266 forms a metal sheet, of substantially constant thickness over its entire length, and whose width is parallel to the axis X7, and therefore to the axis X81 of the pin 81. The stop blade 303 extends along the central part 300, and part of the blade 303 is positioned inside the channel 304, facing the arm 302.

Le corps principal 265 forme deux encoches 314 et 315 en regard, qui contribuent à la solidarisation de l'armature 266 avec le corps principal 265. Ici, l'encoche 314 est ménagée dans la partie centrale 300 du corps principal et l'encoche 315 est ménagée dans le bras 302. L'encoche 314 s'étend hors du canal 304, à partir de la dent 309 incluse. En particulier, l'encoche 314 est formée le long de la rampe 335. L'encoche 315 est formée par la dent 308, et s'étend éventuellement jusqu'à l'extrémité libre du bras 302. Une partie extrémale 324 de l'armature 266, formant ici une partie de la lame d'arrêt 303, est reçue dans l'encoche 314. Une partie extrémale 333 de l'armature 266, opposée à la partie extrémale 324, qui n'appartient pas à la lame d'arrêt 303, est reçue dans l'encoche 315, de sorte que l'armature 266 est fixée par rapport au corps principal 265 suivant l'axe X7, tout en laissant la possibilité à l'armature 266 de se déformer. Sur la figure 8, les portions des parties 324 et 333 reçues dans les encoches 314 et 315 sont montrées en pointillés. Dans l'exemple illustré, l'armature 266 ne comprend pas d'ancre telle que les ancres 112 et 113 à ses extrémités, les parties 324 et 333 ayant une fonction similaire. En variante, on pourrait avantageusement prévoir des ancres en forme de crochet similaires aux ancres 112 et 113, notamment aux extrémités de l'armature 266.The main body 265 forms two facing notches 314 and 315, which contribute to securing the armature 266 to the main body 265. Here, the notch 314 is formed in the central part 300 of the main body and the notch 315 is formed in the arm 302. The notch 314 extends out of the channel 304, from the tooth 309 included. In particular, the notch 314 is formed along the ramp 335. The notch 315 is formed by the tooth 308, and eventually extends to the free end of the arm 302. end 324 of armature 266, here forming part of stop blade 303, is received in notch 314. An end part 333 of armature 266, opposite end part 324, which does not belong to the stop blade 303, is received in the notch 315, so that the armature 266 is fixed relative to the main body 265 along the axis X7, while leaving the possibility for the armature 266 to deform . On the figure 8 , the portions of the parts 324 and 333 received in the notches 314 and 315 are shown in dotted lines. In the example illustrated, the armature 266 does not include an anchor such as the anchors 112 and 113 at its ends, the parts 324 and 333 having a similar function. As a variant, hook-shaped anchors similar to anchors 112 and 113 could advantageously be provided, in particular at the ends of frame 266.

Structurellement, de préférence, la lame d'arrêt 303 forme successivement la partie extrémale 324, formant une rampe, une dent 331, une partie courbe 325 et une dent 332, qui est suivie par la partie extrémale 333. Comme illustré, ces différentes parties sont matérialisées par des courbures locales de l'armature 266.Structurally, preferably, the stop blade 303 successively forms the end part 324, forming a ramp, a tooth 331, a curved part 325 and a tooth 332, which is followed by the end part 333. As illustrated, these different parts are materialized by local curvatures of the armature 266.

Pour toute orientation relative des charnons 3 et 5, au moins une partie de la lame 303 est agencée entre le pion 81 et l'axe X7, en particulier entre le pion 81 et la partie centrale 300 du corps principal 265. Autrement dit, le pion 81 se trouve radialement interposé entre la lame 303 et le bras 302.For any relative orientation of the knuckles 3 and 5, at least a part of the blade 303 is arranged between the pin 81 and the axis X7, in particular between the pin 81 and the central part 300 of the main body 265. In other words, the pin 81 is radially interposed between blade 303 and arm 302.

Pour que l'organe d'arrêt 273 s'oppose ou autorise le pivotement relatif des charnons 3 et 5, on prévoit avantageusement qu'une coopération mécanique s'opère entre le pion 81 et la lame d'arrêt 303, outre la coopération susmentionnée entre le pion 81 et le bras 302. C'est la position de chaque dent et rampe de la lame d'arrêt 303 qui détermine pour quelles orientations les charnons 3 et 5 sont autorisés ou empêchés de pivoter.For the stop member 273 to oppose or authorize the relative pivoting of the knuckles 3 and 5, provision is advantageously made for mechanical cooperation to take place between the pin 81 and the stop blade 303, in addition to the aforementioned cooperation. between the pin 81 and the arm 302. It is the position of each tooth and ramp of the stop blade 303 which determines for which orientations the knuckles 3 and 5 are authorized or prevented from pivoting.

La partie courbe 325 de la lame 303 est disposée au fond du canal 304 et sert ainsi de butée pour le pivotement des charnons 3 et 5, en accueillant le pion 81 en son sein pour borner la fin de courses du pivotement relatif des charnons 3 et 5. En particulier, la partie courbe 325 constitue une butée, contre laquelle le pion 81 vient en butée orthoradiale lorsque les charnons 3 et 5 sont dans l'orientation P2, ce qui borne le pivotement des charnons 3 et 5 à l'orientation P2. Autrement dit, l'orientation P2 est une fin de course de pivotement des charnons 3 et 5 imposée par le dispositif 209. Le dispositif 209 ne forme pas de fin de course pour l'orientation P1. La partie courbe 325 présente avantageusement une courbure qui épouse une paroi périphérique du pion 81, ici cylindrique à base circulaire centrée sur l'axe X81. Le fait de prévoir que l'armature 266 forme la butée de fin de course en pivotement des charnons 3 et 5 pour la position P2, en armant le bras 302 s'il est prévu, assure une excellente durabilité du dispositif 209, dont l'organe d'arrêt 273 présente moins de chance d'être rompu si la porte du véhicule subit un effort qui tend à orienter les charnons 3 et 5 au-delà de la fin de course autorisée par le dispositif 209.The curved part 325 of the blade 303 is arranged at the bottom of the channel 304 and thus serves as a stop for the pivoting of the knuckles 3 and 5, by accommodating the pin 81 within it to limit the end of the relative pivoting strokes of the knuckles 3 and 5. In particular, the curved part 325 constitutes an abutment, against which the pin 81 comes into orthoradial abutment when the knuckles 3 and 5 are in the orientation P2, which limits the pivoting of the knuckles 3 and 5 to the orientation P2 . In other words, the orientation P2 is a limit switch for the pivoting of the knuckles 3 and 5 imposed by the device 209. The device 209 does not form a limit switch for the orientation P1. The curved part 325 advantageously has a curvature which hugs a peripheral wall of the pin 81, here cylindrical with a circular base centered on the axis X81. The fact of providing that the armature 266 forms the limit stop in pivoting of the knuckles 3 and 5 for the position P2, by arming the arm 302 if provided, ensures excellent durability of the device 209, the stopper 273 has less chance of being broken if the door of the vehicle undergoes a force which tends to orient the knuckles 3 and 5 beyond the end of travel authorized by the device 209.

En variante, chaque butée, ou l'une des butées, est assurée seulement par le bras 302, sans recours à l'armature 266.Alternatively, each stop, or one of the stops, is ensured only by the arm 302, without recourse to the armature 266.

Dans le présent exemple, l'organe d'arrêt 273 met en oeuvre à la fois une coopération de la charnière 1 avec la lame d'arrêt 303 et avec le corps principal 265 pour indexer l'orientation des charnons 3 et 5.In the present example, the stop member 273 implements both a cooperation of the hinge 1 with the stop blade 303 and with the main body 265 to index the orientation of the knuckles 3 and 5.

Comme visible sur la figure 8, la dent 331 est agencée pour s'opposer au pivotement des charnons 3 et 5 lorsque les charnons 3 et 5 sont dans l'orientation P2. Pour cela, de préférence, la dent 331 est tournée radialement vers l'extérieur, c'est-à-dire à l'opposé de l'axe X7, alors que la lame 303 borde le pion 81 radialement vers l'intérieur. Le pion 81 vient alors en butée orthoradiale contre la dent 331. La dent 331 constitue un obstacle que le pion 81 doit franchir pour autoriser les charnons 3 et 5 à pivoter par-delà l'orientation P2, en direction notamment du secteur S0 ou de l'orientation P1. Réciproquement, la dent 331 constitue un obstacle que le pion 81 doit franchir pour autoriser les charnons 3 et 5 à pivoter jusqu'à l'orientation P2, alors que les charnons étaient notamment dans le secteur S0 ou dans l'orientation P1. Le franchissement de la dent 331 par le pion 81 est effectué par déformation élastique de la lame 303, suivant une direction radiale interne. De préférence, la dent 331 et la dent 309 sont superposées, puisque la lame 303 est implantée dans la partie centrale 300 à partir de la dent 309, comme expliqué ci-avant. Autrement dit, la dent 309 est armée par la dent 331.As seen on the figure 8 , the tooth 331 is arranged to oppose the pivoting of the knuckles 3 and 5 when the knuckles 3 and 5 are in the orientation P2. For this, tooth 331 is preferably turned radially outward, that is to say opposite axis X7, while blade 303 borders pin 81 radially inward. The pin 81 then comes into orthoradial abutment against the tooth 331. The tooth 331 constitutes an obstacle that the pin 81 must cross to allow the knuckles 3 and 5 to pivot beyond the orientation P2, in the direction in particular of the sector S0 or of orientation P1. Conversely, tooth 331 constitutes an obstacle that pin 81 must cross to allow knuckles 3 and 5 to pivot to orientation P2, whereas the knuckles were in particular in sector S0 or in orientation P1. The crossing of the tooth 331 by the pin 81 is performed by elastic deformation of the blade 303, in an internal radial direction. Preferably, the tooth 331 and the tooth 309 are superimposed, since the blade 303 is implanted in the central part 300 from the tooth 309, as explained above. In other words, tooth 309 is armed by tooth 331.

Comme visible sur la figure 8, la dent 332 est agencée pour s'opposer au pivotement des charnons 3 et 5 lorsque les charnons 3 et 5 sont dans l'orientation P2. Pour cela, de préférence, la dent 332 est tournée radialement vers l'intérieur, alors que la lame 303 borde le pion 81 radialement vers l'extérieur. Si la dent 331 est prévue, les dents 331 et 332 sont avantageusement disposées en regard, de sorte à former une pince qui borde le canal 304. Le pion 81 vient alors en butée orthoradiale contre la dent 332. La dent 332 constitue un obstacle que le pion 81 doit franchir pour autoriser les charnons 3 et 5 à pivoter par-delà l'orientation P2, en direction notamment du secteur S0 ou de l'orientation P1. Réciproquement, la dent 332 constitue un obstacle que le pion 81 doit franchir pour autoriser les charnons 3 et 5 à pivoter jusqu'à l'orientation P2, alors que les charnons étaient notamment dans le secteur S0 ou dans l'orientation P1. Le franchissement de la dent 332 par le pion 81 est effectué par déformation élastique de la lame 303, suivant une direction radiale externe. De préférence, la dent 332 et la dent 308 sont superposées, puisque la lame 303 est implantée dans le bras 302 à partir de la dent 308, comme expliqué ci-avant. Autrement dit, la dent 308 est armée par la dent 332. Les dents 331, 332, 108 et 109 assurent donc ensemble que l'organe 273 s'oppose au pivotement de la charnière 1 hors et vers l'orientation P2.As seen on the figure 8 , the tooth 332 is arranged to oppose the pivoting of the knuckles 3 and 5 when the knuckles 3 and 5 are in the orientation P2. For this, tooth 332 is preferably turned radially inwards, while blade 303 borders pin 81 radially outwards. If the tooth 331 is provided, the teeth 331 and 332 are advantageously arranged opposite, so as to form a clamp which borders the channel 304. The pin 81 then comes into orthoradial abutment against the tooth 332. The tooth 332 constitutes an obstacle that the pin 81 must cross to authorize the knuckles 3 and 5 to pivot beyond the orientation P2, in the direction in particular of the sector S0 or of the orientation P1. Conversely, tooth 332 constitutes an obstacle that pin 81 must cross to allow knuckles 3 and 5 to pivot to orientation P2, whereas the knuckles were in particular in sector S0 or in orientation P1. The crossing of the tooth 332 by the pin 81 is carried out by elastic deformation of the blade 303, in an external radial direction. Preferably, the tooth 332 and the tooth 308 are superimposed, since the blade 303 is implanted in the arm 302 from the tooth 308, as explained above. In other words, tooth 308 is armed by tooth 332. Teeth 331, 332, 108 and 109 therefore together ensure that the member 273 opposes the pivoting of the hinge 1 out of and towards the orientation P2.

Vu sous un autre angle, la courbe 325 de la lame 103 s'oppose au pivotement des charnons 3 et 5 lorsque les charnons 3 et 5 sont dans l'orientation P2, les dents 331 et 332 formant les extrémités de cette courbe 325. La courbe 325 est recourbée de sorte à entourer le pion 81 sur plus de la moitié de sa circonférence, à la manière d'une pince, lorsque le pion 81 est dans la position P2.Seen from another angle, the curve 325 of the blade 103 opposes the pivoting of the knuckles 3 and 5 when the knuckles 3 and 5 are in the orientation P2, the teeth 331 and 332 forming the ends of this curve 325. The curve 325 is curved so as to surround pin 81 over more than half of its circumference, like a clamp, when pin 81 is in position P2.

Lorsque les charnons 3 et 5 sont dans le secteur S0, le pion 81 coulisse le long de la rampe 324, de sorte que le pivotement des charnons 3 et 5 est autorisé pour le secteur S0. Cela s'applique également au secteur S1 et aux orientations P1 et P3. On peut optionnellement prévoir que, lorsque les charnons 3 et 5 sont orientés dans le secteur S0, le pion 81 déforme radialement vers l'intérieur, c'est-à-dire vers l'axe X7, l'armature 266 par l'intermédiaire de la rampe 324, de sorte que le pivotement des charnons est amorti par frottement du pion 81 contre la rampe 324. Ainsi, dans le secteur S0, la rampe 335 du corps 265 est armée par la rampe 324 de l'armature 266, de sorte que le dispositif 209 est résistant à l'usure par frottement éventuellement causée par le pion 81 lors de son coulissement le long de ces rampes.When the knuckles 3 and 5 are in the sector S0, the pin 81 slides along the ramp 324, so that the pivoting of the knuckles 3 and 5 is authorized for the sector S0. This also applies to sector S1 and orientations P1 and P3. It is optionally possible to provide that, when the knuckles 3 and 5 are oriented in the sector S0, the pin 81 deforms radially inwards, that is to say towards the axis X7, the armature 266 via of the ramp 324, so that the pivoting of the knuckles is damped by friction of the pin 81 against the ramp 324. Thus, in the sector S0, the ramp 335 of the body 265 is reinforced by the ramp 324 of the armature 266, so that the device 209 is resistant to wear by friction possibly caused by the pin 81 during its sliding along these ramps.

De préférence, le secteur S0 correspond à une orientation stable pour les charnons 3 et 5, le dispositif 209 ne tendant pas particulièrement à ramener les charnons 3 et 5 une orientation particulière telle que l'orientation P2 lorsque les charnons 3 et 5 sont orientés dans le secteur S0. En variante, on prévoit que le secteur S0 correspond à une orientation instable pour les charnons 3 et 5, pour tendre à ramener les charnons soit dans l'orientation P2 soit l'orientation P1 sous l'action de la lame 303 de la partie centrale 300, lorsque les charnons sont dans le secteur S0.Preferably, the sector S0 corresponds to a stable orientation for the knuckles 3 and 5, the device 209 not particularly tending to bring the knuckles 3 and 5 to a particular orientation such as the orientation P2 when the knuckles 3 and 5 are oriented in the S0 sector. As a variant, provision is made for the sector S0 to correspond to an unstable orientation for the knuckles 3 and 5, to tend to bring the knuckles either into the orientation P2 or the orientation P1 under the action of the blade 303 of the central part 300, when the knuckles are in the S0 sector.

De préférence, pour le secteur S1 et la position P1, le pion 81 n'est pas en contact avec le dispositif 9, de sorte que l'orientation de la charnière 1 n'est pas entravée par l'organe 273.Preferably, for sector S1 and position P1, pin 81 is not in contact with device 9, so that the orientation of hinge 1 is not hindered by member 273.

Toute caractéristique décrite ci-avant pour un mode de réalisation ou une variante s'applique aux autres modes de réalisation et variantes décrits ci-dessus, pour autant que techniquement possible, en restant dans les limites des revendications.Any characteristic described above for one embodiment or a variant applies to the other embodiments and variants described above, as far as technically possible, while remaining within the limits of the claims.
