Description

Dispositif de verrouillage d'une sangle de ceinture de sécurité sans pêne. Locking device for a seatbelt webbing without bolt.
La présente invention concerne les dispositifs de verrouillage d'une sangle de ceinture de sécurité pour siège de véhicule automobile, en particulier pour les ceintures de sécurité sans pêne.The present invention relates to the locking devices of a seat belt strap for a motor vehicle seat, in particular for safety belts without bolt.
Plus précisément, l'invention concerne un dispositif de verrouillage d'une sangle de ceinture de sécurité pour siège de véhicule automobile, le dispositif comprenant :More specifically, the invention relates to a device for locking a seat belt strap for a motor vehicle seat, the device comprising:
- une partie supérieure et une partie inférieure solidaires l'une de l'autre par une zone de recouvrement (zone R) , - une gorge entre ladite partie supérieure et ladite partie inférieure, pour le passage de la sangle entre une position libre et une position verrouillée, des moyens de verrouillage de la sangle, configurés pour maintenir la sangle en position verrouillée, etan upper part and a lower part integral with one another by a covering zone (zone R), a groove between said upper part and said lower part, for the passage of the strap between a free position and a locked position, locking means of the strap, configured to hold the strap in the locked position, and
- des moyens de déverrouillage de la sangle.- Unlocking means of the strap.
Un dispositif de ceinture de sécurité sans pêne est connu de l'homme du métier, notamment par l'exemple qu'en donne le document de l'état de la technique antérieure FR2861033 déposé par la demanderesse.A safety belt device without bolt is known to those skilled in the art, particularly by the example given in the document of the prior art FR2861033 filed by the applicant.
L'utilisation d'un pêne amené des contraintes sur l'aspect général des dispositifs de verrouillage, sur la gestuelle de l'utilisateur, ainsi que sur les procédés de montage des dits dispositifs de verrouillage dans un véhicule. En effet, la position du pêne est déterminée par une butée sur la sangle et la position du renvoi de sangle. Ce qui contraint fortement le geste de verrouillage car l'utilisateur doit parvenir à se saisir du pêne .The use of a bolt brought constraints on the general appearance of the locking devices, on the user's gestures, as well as on the methods of mounting said locking devices in a vehicle. Indeed, the position of the bolt is determined by a stop on the strap and the position of the strap return. This strongly constrains the locking gesture because the user must manage to grab the bolt.
De plus, le poids du pêne augmente la traînée de la sangle et contrarie l'action de rappel de l'enrouleur de sangle .In addition, the weight of the bolt increases the drag of the strap and thwarts the return action of the strap winder.
L'orientation du pêne contraint les procédés de montage de la ceinture (ensemble sangle/pêne) pour éviter de monter le pêne à l'envers.The orientation of the bolt constrains the methods of mounting the belt (belt / bolt assembly) to avoid mounting the bolt upside down.
Il existe certains dispositifs de verrouillage de ceinture avec pêne, visant à faciliter le verrouillage. Plus précisément, de tels dispositifs visent à améliorer le guidage du pêne menant au verrouillage, par un pêne en forme de révolution, ce qui conduit à un pêne cylindrique, plus lourd et plus gros.There are certain belt locking devices with bolt, designed to facilitate locking. More specifically, such devices are intended to improve the guidance of the bolt leading to locking, by a bolt in the form of revolution, which leads to a cylindrical bolt, heavier and larger.
La présente invention a pour but de remédier à ces inconvénients en proposant un dispositif particulièrement adapté aux sangles de ceintures de sécurité, exemptes de pêne .The present invention aims to overcome these disadvantages by providing a device particularly suitable for safety belt straps, free of bolt.
Avec cet objectif en vue, le dispositif selon l'invention, par ailleurs conforme au préambule cité ci- avant, est essentiellement caractérisé en ce qu'il comprend en outre :With this objective in view, the device according to the invention, furthermore in accordance with the preamble cited above, is essentially characterized in that it furthermore comprises:
- des moyens anti-écartement susceptibles d'exercer une force s 'opposant à une force d'écartement entre ladite partie supérieure et ladite partie inférieure.- anti-separation means capable of exerting a force opposing a spacer force between said upper portion and said lower portion.
La force d'écartement entre ladite partie supérieure et ladite partie inférieure est susceptible d'être exercée par la sangle sur ladite partie supérieure . Selon l'invention, les moyens anti-écartement sont mobiles entre une configuration active et configuration passive .The spacing force between said upper portion and said lower portion may be exerted by the strap on said upper portion. According to the invention, the anti-separation means are movable between an active configuration and passive configuration.
Avantageusement, les moyens anti-ecartement sont en configuration active au moins lorsque la sangle est en position verrouillée.Advantageously, the anti-spacing means are in active configuration at least when the strap is in the locked position.
Dans un mode de réalisation, les moyens de déverrouillage sont mobiles en translation. Alternativement, ils sont mobiles en rotation. Dans un mode de réalisation, les moyens de verrouillage sont mobiles, et le mouvement des dits moyens de verrouillage est solidaire au moins du mouvement de déverrouillage des dits moyens de déverrouillage . Dans un mode de réalisation, le dispositif selon l'invention comprend en outre des premiers moyens de rappel coopérant avec les moyens anti-écartement .In one embodiment, the unlocking means are movable in translation. Alternatively, they are mobile in rotation. In one embodiment, the locking means are movable, and the movement of said locking means is secured to at least the unlocking movement of said unlocking means. In one embodiment, the device according to the invention further comprises first return means cooperating with the anti-separation means.
Dans un mode de réalisation, le dispositif selon l'invention comprend en outre des deuxièmes moyens de rappel coopérant avec les moyens de déverrouillage.In one embodiment, the device according to the invention further comprises second return means cooperating with the unlocking means.
Dans un mode de réalisation, les moyens anti- écartement comprennent un doigt anti-écartement coopérant avec des logements prévus dans ladite partie supérieure et/ou dans ladite partie inférieure. De préférence, les premiers moyens de rappel sont susceptibles d'adopter une position de repos et une position active, les moyens anti-écartement étant en configuration active au moins lorsque les premiers moyens de rappel sont en position de repos. Grâce a une sangle libre de tout pêne, l'utilisateur peut saisir la sangle en tout point de son choix, en fonction par exemple du véhicule, des réglages du siège, ou de la morphologie de l'utilisateur.In one embodiment, the anti-separation means comprise an anti-separation finger cooperating with housings provided in said upper part and / or in said lower part. Preferably, the first biasing means are capable of adopting a rest position and an active position, the anti-gap means being in the active configuration at least when the first return means are in the rest position. Thanks to a strap free of any bolt, the user can seize the strap at any point of his choice, depending for example on the vehicle, the seat settings, or the morphology of the user.
Grâce à l'invention, la préhension et le bouclage de la ceinture de sécurité sont facilités pour l'utilisateur du véhicule automobile.Thanks to the invention, the gripping and fastening of the seat belt are facilitated for the user of the motor vehicle.
Grâce à l'invention, on peut obtenir une configuration de verrouillage à trois points, compatible avec les ancrages structurels habituels des dispositifs de verrouillage des véhicules automobiles actuels. Grâce à l'invention, on peut éviter les contraintes liées à la présence d'un pêne sur la sangle d'une ceinture de sécurité : contraintes d'aspect général, sur la gestuelle de l'utilisateur ainsi que sur les procédés de montage du pêne sur la sangle.

La sangle 7 de la ceinture de sécurité est illustrée en pointillés. Pour plus de lisibilité des figures, la sangle 7 n'est illustrée que sur la figure IA. Le dispositif selon l'invention comprend une partie supérieure 19 et une partie inférieure 20 solidaires l'une de l'autre par une zone de recouvrement (zone R) .The belt 7 of the safety belt is illustrated in dashed lines. For more legibility of the figures, the strap 7 is illustrated only in Figure IA. The device according to the invention comprises an upper part 19 and a lower part 20 secured to one another by a covering zone (zone R).
Une gorge IN/OUT entre ladite partie supérieure et ladite partie inférieure permet le passage de la sangle entre une position libre, c'est-à-dire hors dispositif, et une position verrouillée, c'est-a-dire maintenue dans le dispositif, en l'espèce en butée au fond de la gorge IN/OUT, lorsque l'utilisateur du véhicule automobile amène manuellement la sangle 7 dans le dispositif de 1' invention .An IN / OUT groove between said upper part and said lower part allows the passage of the strap between a free position, that is to say off device, and a locked position, that is to say maintained in the device , in this case in abutment at the bottom of the groove IN / OUT, when the user of the motor vehicle manually brings the strap 7 into the device 1 of the invention.
La gorge IN/OUT est de préférence en forme de fente ou « avaloir » dont l'épaisseur est légèrement supérieure à celle de la sangle 7, et permet avantageusement de guider la sangle 7. Elle est orientée de préférence de manière oblique dès son ouverture pour favoriser l'entrée IN ou la sortie OUT de sangle de ceinture 7 et se prolonge ensuite de manière sensiblement horizontale afin de positionner la sangle pour le verrouillage. Avantageusement, l'ouverture de la gorge comprend une partie en forme d'évasement.The IN / OUT groove is preferably in the form of a slot or "throat" whose thickness is slightly greater than that of the strap 7, and advantageously allows the strap 7 to be guided. It is preferably oriented obliquely as soon as it is opened. to favor the IN input or the belt strap outlet OUT 7 and then extends substantially horizontally to position the strap for locking. Advantageously, the opening of the groove comprises a portion in the form of flare.
Le guidage est fait, pour une opération de verrouillage, dans un premier temps suivant une orientation longitudinale au véhicule et sensiblement oblique, puis vers une position de verrouillage sensiblement horizontale, qui constitue alors une position optimale de verrouillage lorsque la sangle 7 est en butée au fond de la gorge. Le guidage est fait inversement pour une opération de déverrouillage . Le premier couvercle 1 et le deuxième couvercle 2 sont sensiblement symétriques, c'est-à-dire symétrique sauf dans les zones ou sont situées les vis de fixation 6 : le premier couvercle 1 comporte une zone d'appui aménagée en creux pour les têtes des vis 6 et les trous de passage de ces mêmes vis, et le deuxième couvercle 2 comporte les taraudages dans lesquels vrennent se vrsser lesdites vis 6.For a locking operation, the guiding is carried out initially in a longitudinal orientation to the vehicle and substantially obliquely, then towards a substantially horizontal locking position, which then constitutes an optimum locking position when the strap 7 is in abutment with the bottom of the throat. The guidance is done inversely for an unlocking operation. The first cover 1 and the second cover 2 are substantially symmetrical, that is to say symmetrical except in the areas where the fixing screws 6 are located. the first cover 1 comprises a support zone arranged in hollow for the heads of the screws 6 and the holes for the passage of these same screws, and the second cover 2 comprises the threads in which the said screws 6 are screwed.
Avantageusement, du fait de la position vers l'avant du bouton de déverrouillage 3 et de la forme sensiblement symétrique des couvercles 1 et 2, le dispositif selon l'invention illustré sur les figures 1 à 4 peut être monté sur n' importe quel siège : conducteur ou passager, avant ou arrière d'un véhicule.Advantageously, because of the forward position of the unlocking button 3 and the substantially symmetrical shape of the covers 1 and 2, the device according to the invention illustrated in FIGS. 1 to 4 can be mounted on any seat. : driver or passenger, front or rear of a vehicle.
Le dispositif selon l'invention comprend également des moyens de verrouillage 15 de la sangle, configurés pour maintenir la sangle en position verrouillée, en l'espèce une butée 15 (figures IB, 2, 3A, 4, 5, 6 et I)1 et des moyens de déverrouillage 3 de la sangle, en l'espèce un bouton (toutes figures) .The device according to the invention also comprises locking means 15 of the strap, configured to maintain the strap in the locked position, in this case a stop 15 (Figures IB, 2, 3A, 4, 5, 6 and I) 1 and unlocking means 3 of the strap, in this case a button (all figures).
Selon l'invention, les moyens de verrouillage 15 sont mobiles. Sur les figures 2 à 4, les moyens de verrouillage 15 sont intégrés aux moyens de déverrouillage 3.According to the invention, the locking means 15 are movable. In FIGS. 2 to 4, the locking means 15 are integrated with the unlocking means 3.
Alternativement, sur les figures 5 à 7, les moyens de verrouillage 15 sont distincts des moyens de déverrouillage 3, et coopèrent avec ceux-ci. Ainsi, quel que soit le mode de réalisation, le mouvement des dits moyens de verrouillage 15 est solidaire au moins du mouvement de déverrouillage des dits moyens de déverrouillage 3.Alternatively, in FIGS. 5 to 7, the locking means 15 are distinct from the unlocking means 3 and cooperate with them. Thus, whatever the embodiment, the movement of said locking means 15 is integral at least with the unlocking movement of said unlocking means 3.
Le dispositif selon l'invention comprend également des moyens anti-écartement 9, susceptibles d'exercer une force s 'opposant à une force d'écartement entre ladite partie supérieure 19 et ladite partie inférieure 20; la force d' écartement entre ladrte partie supérieure et ladite partie inférieure étant susceptible d'être exercée par la sangle 7 sur ladite partie supérieure 19, notamment lors d'une décélération soudaine et forte du véhicule, par exemple lors d'un freinage brusque ou d'un accident .The device according to the invention also comprises anti-separation means 9, capable of exerting a force opposing a spacer force between said upper part 19 and said lower part 20; the spreading force between said upper part and said lower part being able to be exerted by the strap 7 on said upper part 19, in particular during a sudden and strong deceleration of the vehicle, for example during a sudden braking or 'an accident .
En l'espèce, les moyens anti-écartements comprennent un doigt anti-écartement 9, coopérant avec au moins un logement 11 prévu dans ladite partie supérieure et/ou dans ladite partie inférieure.In this case, the anti-spacing means comprise an anti-spacing finger 9, cooperating with at least one housing 11 provided in said upper part and / or in said lower part.
Dans les modes de réalisation illustres, le logement 11 est en l'espèce circulaire et situé dans la partie supérieure 19. D'autres configurations sont possibles, par exemple dans lesquelles le logement 11 est situé dans la partie inférieure 20.In the illustrative embodiments, the housing 11 is in this case circular and located in the upper part 19. Other configurations are possible, for example in which the housing 11 is located in the lower part 20.
Selon l'invention, les moyens anti-écartements 9 sont mobiles entre une configuration active et configuration passive.According to the invention, the anti-spacing means 9 are movable between an active configuration and passive configuration.
En configuration active, les moyens anti- écartements 9 sont susceptibles d'exercer une force s 'opposant à une force d' écartement entre ladite partie supérieure et ladite partie inférieure, en l'espèce quand le doigt 9 est dans le logement 11 (figures IB, 2A, 2B, 5A, 5B, 5C, 7A, 7B) . En configuration passive, les moyens anti- écartements 9 ne sont pas susceptibles d'exercer ladite force d'opposition, par exemple lors du passage de la sangle 7 dans ladite gorge lors d'une opération de verrouillage (figures 3A, 3B, 6A, 6B) ou de déverrouillage (figures 4A, 4B) et de sortie de la sangle 7 du dispositif selon l'invention, comme décrit ultérieurement . Selon l'invention, les moyens anti-écartements 9 sont en configuration active au moins lorsque la sangle 7 est en position verrouillée.In the active configuration, the anti-clearance means 9 are able to exert a force opposing a spreading force between said upper part and said lower part, in this case when the finger 9 is in the housing 11 (FIGS. IB, 2A, 2B, 5A, 5B, 5C, 7A, 7B). In passive configuration, the anti-spacing means 9 are not capable of exerting said opposing force, for example during the passage of the strap 7 in said groove during a locking operation (FIGS. 3A, 3B, 6A, 6B) or unlocking (Figures 4A, 4B) and output of the strap 7 of the device according to the invention, as described later. According to the invention, the anti-spacing means 9 are in active configuration at least when the strap 7 is in the locked position.
De préférence, le dispositif selon l'invention comprend en outre des premiers moyens de rappel 12 coopérant avec les moyens anti-écartements 9.Preferably, the device according to the invention further comprises first return means 12 cooperating with the anti-separation means 9.
Le dispositif selon l'invention peut également comprendre des deuxièmes moyens de rappel 14 coopérant avec les moyens de déverrouillage 3. En l'espèce, les premiers moyens de rappel 12 et les deuxièmes moyens de rappel 14 comprennent des ressorts de tension.The device according to the invention may also comprise second return means 14 cooperating with the unlocking means 3. In this case, the first return means 12 and the second return means 14 comprise tension springs.

Le dispositif selon l'invention comporte deux modes de réalisation principaux.The device according to the invention comprises two main embodiments.
Dans un mode de réalisation, les moyens de déverrouillage 3 sont mobiles en rotation (figures 1, 2, 3 et 4). En l'espèce, les moyens de déverrouillage 3 sont mobiles autour d'un axe 5 de rotation : le bouton 3 pivote autour de l'axe 5 lorsqu'un utilisateur appuie sur le bouton, ce qui permet de libérer, déverrouiller, la sangle 7.In one embodiment, the unlocking means 3 are movable in rotation (FIGS. 1, 2, 3 and 4). In this case, the unlocking means 3 are movable about an axis of rotation: the button 3 pivots about the axis 5 when a user presses the button, which allows to release, unlock, the strap 7.
Dans un autre mode de réalisation, les moyens de déverrouillage 3 sont mobiles en translation (figures 5, 6 et 7) . Le fonctionnement du dispositif selon l'invention lors d'une opération de verrouillage est illustré aux figures 3A et 3B ; et aux figures 6A et 6B .In another embodiment, the unlocking means 3 are movable in translation (Figures 5, 6 and 7). The operation of the device according to the invention during a locking operation is illustrated in FIGS. 3A and 3B; and Figures 6A and 6B.
Lors d'une opération de verrouillage, un utilisateur amène manuellement la sangle 7 de l'extérieur du dispositif (position libre de la sangle) vers la position de verrouillage en butée au fond de la gorgeDuring a locking operation, a user manually brings the strap 7 from the outside of the device (free position of the strap) to the locking position in abutment at the bottom of the throat
IN/OUT.IN / OUT.
Comme illustré aux figures 3A et 3B dans lesquelles les moyens de déverrouillage 3 sont mobiles en rotation, lors du passage de la sangle 7 dans la gorge, dans un premier temps, la sangle fait basculer autour d'un axe 10, en l'espèce dans le sens inverse des aiguilles d'une montre, le doigt anti-écartement 9. Des logements circulaires 11 sont prévus à l'intérieur des couvercles 1 et 2 pour permettre le débattement du doigt anti- écartement 9 avec un jeu réduit pour son efficacité.As illustrated in FIGS. 3A and 3B in which the unlocking means 3 are movable in rotation, during the passage of the strap 7 in the groove, in a first step, the strap tilts about an axis 10, in this case anti-clockwise, the anti-spacing finger 9. Circular housings 11 are provided inside the covers 1 and 2 to allow the clearance of the anti-gap finger 9 with a reduced clearance for its effectiveness .
Le basculement du doigt anti-écartement 9 met en contrainte des ressorts de tension 12 (au moment du passage de la sangle de ceinture 7) qui adoptent alors une position active et agissent sur le doigt anti- écartement 9 afin de le ramener à sa position de repos (illustrée figures 2A et 2B par exemple) .The tilting of the anti-spreading finger 9 puts in tension tension springs 12 (at the moment of the passage of the belt strap 7) which then adopt an active position and act on the anti-spreading finger 9 in order to bring it back to its position. rest (illustrated in Figures 2A and 2B for example).
Dans un deuxième temps, en l'espèce avant la fin du basculement complet du doigt anti-écartement 9 (c'est-à- dire au-delà de la gorge IN/OUT) , la sangle 7 vient appuyer sur la face supérieure des butées de sangle 15, aménagées en l'espèce en partie centrale supérieure du bouton de déverrouillage 3. Par cette poussée sur les butées 15, le bouton de déverrouillage 3 bascule, en l'espèce dans le sens des aiguilles d'une montre vers le bas, autour de l'axe 5 jusqu'à ce que le passage dans la gorge soit libéré pour laisser passer la sangle de ceinture 7 jusqu'à sa position de verrouillage, en l'espèce sensiblement horizontale . Des ressorts de tension 14 adoptent alors une position active, c'est-à-dire sont ainsi mis en contrainte, et s'opposent au mouvement du bouton de déverrouillage 3 afin de le ramener à sa position initiale de repos, en l'espèce vers le haut, lorsque la sangle de ceinture 7 est passée. Les ressorts de tension 12 et 14 sont de préférence maintenus grâce aux mêmes axes 13 sur lesquels ils sont décalés axialement.In a second step, in this case before the end of the complete tilting of the anti-separation finger 9 (that is to say beyond the groove IN / OUT), the strap 7 presses on the upper face of the strap stops 15, arranged in this case in the upper central part of the unlocking button 3. By this pushing on the stops 15, the unlocking button 3 switches, in this case clockwise towards the low, around axis 5 until the passage in the groove is released to let the belt strap 7 to its locking position, in this case substantially horizontal. Tensile springs 14 then adopt an active position, that is to say are thus put under stress, and oppose the movement of the unlocking button 3 to bring it back to its initial rest position, in this case upwards, when the belt strap 7 has passed. The tension springs 12 and 14 are preferably held by the same axes 13 on which they are axially offset.
Une variante dans laquelle les moyens de déverrouillage 3 sont mobiles en translation est illustrée notamment aux figures 6A et 6B .A variant in which the unlocking means 3 are movable in translation is illustrated in particular in Figures 6A and 6B.
Dans ce mode de réalisation, les couvercles 1 et 2 ne sont plus symétriques du fait du positionnement latéral du bouton de déverrouillage 3, qui a dans le cas présent uniquement un mouvement de translation possible, en l'espèce sensiblement vertical.In this embodiment, the covers 1 and 2 are no longer symmetrical due to the lateral positioning of the unlocking button 3, which in this case has only a possible translational movement, in this case substantially vertical.
Par la position latérale du bouton de déverrouillage 3, le dispositif illustré est de préférence destiné à un siège conducteur pour un véhicule avec une direction à gauche ainsi qu'aux places gauche et éventuellement du milieu de siège (s) ou banquette arrière. Pour les autres sièges, le dispositif devra être symétrique au dispositif illustré.By the lateral position of the unlocking button 3, the illustrated device is preferably intended for a driver's seat for a vehicle with a steering on the left as well as the left places and possibly the middle seat (s) or rear seat. For other seats, the device must be symmetrical to the device shown.
On notera par ailleurs que la gorge est identique au dispositif précédemment décrit. De même que dans le mode de réalisation précédemment décrit, lors du passage de la sangle 7 dans la gorge, dans un premier temps, celle-ci fait basculer autour d'un axe 10, en l'espèce dans le sens inverse des aiguilles d'une montre, le doigt anti-écartement 9. Des logements circulaires 11 sont prévus à l'intérieur des couvercles 1 et 2 pour permettre le débattement du doigt anti-écartement 9 avec un jeu réduit pour son efficacité.Note also that the groove is identical to the device described above. As in the embodiment described above, during the passage of the strap 7 in the groove, at first, it tilts around an axis 10, in this case counterclockwise, the anti-spacing finger 9. Circular housings 11 are provided inside the covers 1 and 2 to allow the movement of the finger anti-gap 9 with reduced play for its effectiveness.
Le basculement du doigt anti-écartement 9 met en contrainte, c'est-à-dire en position active, au moment du passage de la sangle de ceinture 7, des ressorts de tension 12, maintenus grâce aux axes 13, et qui agissent sur le doigt anti-écartement 9 afin de le ramener à sa position initiale en configuration active (illustrée figures 5A, 5B et 5C par exemple) .The tilting of the anti-separation finger 9 puts into stress, that is to say in the active position, at the moment of the passage of the belt strap 7, the tensioning springs 12, held by the axes 13, and acting on the anti-separation finger 9 to bring it back to its initial position in active configuration (illustrated in FIGS. 5A, 5B and 5C, for example).
Dans un deuxième temps, en l'espèce avant la fin du basculement complet du doigt anti-écartement 9 (c'est-a- dire au-delà de la gorge IN/OUT) , la sangle 7 vient appuyer sur la face supérieure des butées de sangle 15, aménagées en l'espèce en partie centrale supérieure du bouton de deverrouillage 3.In a second step, in this case before the end of the complete tilting of the anti-separation finger 9 (that is to say beyond the groove IN / OUT), the strap 7 presses on the upper face of the strap stops 15, arranged in this case in the upper central part of the unlocking button 3.
Le doigt anti-écartement 9 est décalé et indépendant de la butée de sangle 15.The anti-separation finger 9 is offset and independent of the web stop 15.
Contrairement au mode de réalisation précédent, la butée de sangle 15 est mobile en rotation, et s'articule en l'espèce autour d'un axe 16 solidaire du bouton de deverrouillage 3. Sous l'action de la sangle 7 la butée de sangle 15 pivote donc, en l'espèce dans le sens inverse des aiguilles d'une montre, pour laisser passer la sangle 7 sans agir dans le cas illustré sur le bouton de deverrouillage 3. Des moyens de rappel, en l'espèce un ressort de torsion 17, est configuré pour rappeler/maintenir la butée de sangle 15 en position de repos (en l'espèce haute) et en appui sur une forme adaptée du bouton de déverrouillage 3, la force de rappel exercée s' opposant au pivotement, en l'espèce vers le bas, de la butée de sangle 15. Le bouton de déverrouillage 3 reste, dans cette phase de manœuvre de l'utilisateur, sous l'action d'un ressort à lame 14 en position de repos (en l'espèce haute) par l'intermédiaire d'un ergot 18 solidaire en butée haute d'un trou oblong situé dans l'élément de liaison 4 (figure 5A) .Unlike the previous embodiment, the strap stop 15 is rotatable, and is articulated in this case around an axis 16 secured to the unlocking button 3. Under the action of the strap 7 the strap stopper 15 rotates, in this case in the opposite direction of the clockwise, to let the strap 7 without acting in the case illustrated on the unlocking button 3. Reminder means, in this case a spring of twist 17, is configured to recall / maintain the strap stop 15 in the rest position (in this case high) and resting on a suitable form of the unlocking button 3, the restoring force exerted opposing the pivoting, in this case downwards, of the strap stop 15. The unlocking button 3 remains, in this case, phase of maneuvering the user, under the action of a leaf spring 14 in the rest position (in this case high) by means of a lug 18 secured to the upper stop of an oblong hole located in the connecting element 4 (FIG. 5A).
On notera que le fonctionnement et le type de butée de sangle 15 de cette variante peut être adapté au mode de réalisation précédemment décrit dans lequel le bouton de déverrouillage 3 est monte à rotation et ne serait alors plus actionné lors de l'entrée de la sangle 7.Note that the operation and the type of strap stop 15 of this variant can be adapted to the embodiment described above in which the unlocking button 3 is rotatably mounted and then no longer actuated when entering the strap 7.
Le dispositif selon l'invention en position de verrouillage est illustré aux figures 2A et 2B ; et aux figures 5A, 5B et 5C.The device according to the invention in the locking position is illustrated in FIGS. 2A and 2B; and Figures 5A, 5B and 5C.
Comme illustré aux figures 2A et 2B dans lesquelles les moyens de déverrouillage 3 sont mobiles en rotation, lorsque l'utilisateur amène la sangle 7 en position de verrouillage, celle-ci libère dans un premier temps, le doigt anti-écartement 9 qui revient à sa position initiale (configuration active) grâce aux ressorts de tension 12.As illustrated in Figures 2A and 2B in which the unlocking means 3 are rotatable, when the user brings the strap 7 in the locking position, it releases in a first time, the anti-gap finger 9 which amounts to its initial position (active configuration) thanks to the tension springs 12.
Dans un deuxième temps, les butées de sangle 15, en l'espèce intégrées au bouton de déverrouillage 3, remontent grâce aux ressorts de tension 14 qui adoptent une position de repos empêchant alors la sortie OUT de la sangle 7, en obturant la gorge. Dans cette position, la sangle 7 est en butée d'une part au fond de la gorge et d'autre part au niveau des faces latérales des butées de sangle 15.In a second step, the strap stops 15, in this case integrated with the unlocking button 3, go up again thanks to the tensioning springs 14 which adopt a rest position thus preventing the output OUT of the strap 7, by closing the groove. In this position, the strap 7 abuts on the one hand at the back of the throat and on the other hand at the side faces of the strap stops 15.
Toutefois, en position de verrouillage, la sangle 7 peut quand même coulisser, en l'espèce transversalement, afin de permettre l'ajustement entre brin baudrierHowever, in the locking position, the strap 7 can still slide, in this case transversely, to allow the adjustment between the shoulder strand
(buste) et brin ventral, comme dans les dispositifs actuels .(bust) and ventral strand, as in current devices.
Autrement dit, en position de verrouillage, la sangle 7 ne conserve qu'un seul degré de liberté de mouvement, en l'espèce perpendiculaire à la gorge du dispositif .In other words, in the locking position, the strap 7 retains only one degree of freedom of movement, in this case perpendicular to the groove of the device.
On obtient ainsi une configuration de retenue à trois points, compatible avec les ancrages structurels habituels des dispositifs de verrouillage de véhicule automobile.A three-point retaining configuration is thus obtained, compatible with the usual structural anchorages of motor vehicle locking devices.
Comme illustré aux figures 5A, 5B et 5C dans lesquelles les moyens de déverrouillage 3 sont mobiles en translation, lorsque l'utilisateur amené la sangle de ceinture 7 en position de verrouillage, celle-ci libère, dans un premier temps le doigt anti-écartement 9 qui revient à sa position initiale de repos en configuration active grâce au ressort de tension 12.As illustrated in FIGS. 5A, 5B and 5C in which the unlocking means 3 are movable in translation, when the user brings the belt strap 7 into the locking position, the latter releases, initially, the anti-separation finger 9 which returns to its initial position of rest in active configuration thanks to the tension spring 12.
Dans un deuxième temps, la butée de sangle 15 remonte grâce au ressort de torsion 17 pour se mettre en appui sur une forme adaptée du bouton de déverrouillage 3 et empêche la sortie de la sangle 7, en l'espèce longitudinale, de même que précédemment en obturant la gorge. Toutefois, de même que dans le mode de réalisation précédemment décrit, la sangle 7 conserve la possibilité de coulisser transversalement dans la gorge.In a second step, the strap abutment 15 rises thanks to the torsion spring 17 to bear on a suitable form of the release button 3 and prevents the exit of the strap 7, in this longitudinal case, as before by closing the throat. However, as in the embodiment described above, the strap 7 retains the ability to slide transversely in the groove.
La forme adaptée du bouton de déverrouillage 3 et de la butée de sangle 15 est illustrée par exemple figure 5C ou figure 6B dans laquelle chaque élément (bouton de déverrouillage ou butée de sangle) comprend un prcot ou ergot pouvant être mis en butée d'un picot ou ergot de l'élément correspondant (butée de sangle ou bouton de déverrouillage respectivement) .The adapted form of the release button 3 and the strap stop 15 is illustrated for example in FIG. 5C or 6B in which each element (release button or strap stop) comprises a prcot or lug that can be abutted by a pin or lug of the corresponding element (strap stop or release button respectively).
Grâce à cette configuration, les moyens de verrouillage 15 sont mobiles, et le mouvement des dits moyens de verrouillage 15 est solidaire au moins du mouvement de déverrouillage des dits moyens de déverrouillage 3.Thanks to this configuration, the locking means 15 are movable, and the movement of said locking means 15 is secured to at least the unlocking movement of said unlocking means 3.
Le fonctionnement du dispositif selon l'invention lors d'une opération de déverrouillage est illustré aux figures 4A et 4B ; et aux figures 7A et 7B.The operation of the device according to the invention during an unlocking operation is illustrated in FIGS. 4A and 4B; and Figures 7A and 7B.
Comme illustré aux figures 4A et 4B dans lesquelles les moyens de déverrouillage 3 sont mobiles en rotation, lors d'une opération de déverrouillage, lorsque l'utilisateur veut libérer la sangle 1, il appuie sur le bouton de déverrouillage 3. Celui-ci effectue alors une rotation, en l'espèce dans le sens des aiguilles d'une montre, ce qui provoque la descente des butées de sangle 15 et libère de fait le passage dans la gorge pour la sortie de la sangle 7 que l'utilisateur n'a plus qu'à pousser vers l'avant pour se libérer.As illustrated in FIGS. 4A and 4B, in which the unlocking means 3 are rotatable, during an unlocking operation, when the user wishes to release the strap 1, he presses the unlocking button 3. This performs then a rotation, in this case in the direction of clockwise, which causes the descent of the strap stops 15 and releases the passage in the groove for the exit of the strap 7 that the user does not more than pushing forward to break free.
Comme illustré aux figures 7A et 7B dans lesquelles les moyens de déverrouillage 3 sont mobiles en translation, lors d'une opération de déverrouillage, lorsque l'utilisateur veut libérer la sangle 7, il appuie sur le bouton de déverrouillage 3 qui effectue alors une translation, en l'espèce sensiblement verticale vers le bas, ce qui provoque la descente de butée de sangle 15 libérant ainsi le passage dans la gorge pour la sortie de la sangle 7 que l'utilisateur n'a plus qu'à pousser vers l'avant pour se libérer.As illustrated in FIGS. 7A and 7B in which the unlocking means 3 are movable in translation, during an unlocking operation, when the user wants to release the strap 7, he presses the unlocking button 3, which then performs a translation , in this case substantially vertically downwards, which causes the abutment of strap stop 15 thus releasing the passage in the groove for the exit of the strap 7 that the user only has to push forward to release.
Dans l'un ou l'autre des modes de réalisation, de manière similaire à une opération de verrouillage, le doigt anti-écartement 9 pivote sous l'action du mouvement de la sangle 7 et adopte alors une configuration passive. Cette rotation du doigt anti-écartement 9 met en contrainte le ressort de tension 12, ce qui permet de ramener ensuite le doigt anti-écartement 9 à sa position initiale (configuration active) lorsque la sangle 7 est sortie de la gorge.In either embodiment, in a manner similar to a locking operation, the anti-gap finger 9 pivots under the action of the movement of the strap 7 and then adopts a passive configuration. This rotation of the anti-spreading finger 9 puts in stress the tension spring 12, which then makes it possible to return the anti-separation finger 9 to its initial position (active configuration) when the strap 7 is out of the groove.
L'invention n'est pas limitée aux modes de réalisation précédemment décrits, on peut prévoir par exemple, dans chaque mode de réalisation, que le dispositif selon l'invention comprenne en outre des moyens de sortie automatique de la sangle 7 de sa position de verrouillage, configurés pour pousser la sangle 7 vers la sortie de la gorge lors d'une opération de déverrouillage .
