Description

TITRE : Renfort pour un support d’enrouleur de ceinture de sécurité de véhicule. TITLE: Reinforcement for a vehicle seat belt retractor support.
Domaine technique de l'invention Technical field of the invention
L’invention concerne un agencement comprenant un moyen de rig idif ication pour un support d’enrouleur de sangle de ceinture de sécurité de véhicule. L’invention porte encore sur une caisse comprenant un tel agencement. L’invention porte encore sur un véhicule comprenant une telle caisse ou un tel agencement. The invention relates to an arrangement comprising rigging means for a vehicle seat belt strap retractor support. The invention also relates to a box comprising such an arrangement. The invention also relates to a vehicle comprising such a body or such an arrangement.
Etat de la technique antérieure State of the prior art
Un véhicule, en particulier un véhicule automobile, comprend généralement un dispositif de ceinture de sécurité au niveau de chaque place assise. Un tel dispositif comprend généralement une sangle et un enrouleur d’une telle sangle. Une telle sangle est déroulée depuis son enrouleur afin d’obtenir du mou sur une telle sangle pour la bloucler aisément par l’utilisateur souhaitant s’attacher. Un tel verrouillage est obtenu par l’intermédiaire d’un moyen de bouclage généralement agencé au niveau de l’assise. Un tel enrouleur comprend généralement un moyen de limitation ou blocage du déroulement de la sangle. Un tel enrouleur est généralement agencé verticalement afin que son moyen de limitation du déroulement soit parfaitement opérationnel. Un tel enrouleur est agencé de sorte à permettre un emplacement de la sangle satisfaisant des contraintes en termes d’ergonomie et de sécurité. Ainsi un renvoi est généralement agencé à proximité de l’enrouleur de sorte à permettre à une telle sangle de s’étendre dans une zone définie, en particulier une zone compatible avec les différentes tailles des passagers. A vehicle, in particular a motor vehicle, generally includes a seat belt device at each seat. Such a device generally comprises a strap and a reel of such a strap. Such a strap is unwound from its reel in order to obtain slack on such a strap so that it can be easily blocked by the user wishing to attach themselves. Such locking is obtained by means of a looping means generally arranged at the level of the seat. Such a reel generally includes a means of limiting or blocking the unwinding of the strap. Such a reel is generally arranged vertically so that its means of limiting unwinding are perfectly operational. Such a reel is arranged so as to allow a location of the strap satisfying constraints in terms of ergonomics and safety. Thus a return is generally arranged near the reel so as to allow such a strap to extend in a defined area, in particular an area compatible with the different sizes of passengers.
Notamment en cas de freinage, voire de choc, un tel moyen de limitation de l’enrouleur bloque la sangle ce qui empêche la sangle de se dérouler librement. Il en résulte la retenue du passager attaché avec un tel dispositif de ceinture de sécurité, en particulier vers l’avant du véhicule, ce qui lui évite des blessures et/ou d’être éjecté du véhicule. En cas de freinage du véhicule et/ou choc, un effort conséquent tire donc vers l’avant la sangle de ceinture de sécurité du fait de la mise en action du moyen de limitation du déroulement de sangle. L’effort sur la sangle est alors reprise par l’enrouleur et par le renvoi de sangle. Particularly in the event of braking, or even an impact, such a means of limiting the reel blocks the strap which prevents the strap from unwinding freely. This results in the restraint of the passenger attached with such a seat belt device, in particular towards the front of the vehicle, which gives him prevents injury and/or being ejected from the vehicle. In the event of vehicle braking and/or impact, a significant effort therefore pulls the seat belt strap forward due to the activation of the means for limiting the unwinding of the strap. The force on the strap is then taken up by the reel and by the strap return.
Un tel enrouleur et un tel renvoi nécessitent donc d’être fixés rigidement. Seulement, l’emplacement d’un tel renvoi est immuable. De plus, un support d’enrouleur traversé par la sangle de ceinture fragilise la fixation d’un tel enrouleur. Ces contraintes de rigidité sont particulièrement complexes à satisfaire derrière un second rang ou rang arrière d’un véhicule déjà fortement encombré. Notamment, une coupelle de fixation d’un amortisseur arrière, derrière un tel second rang ainsi qu’un pied extrême arrière venant à proximité d’un tel rang arrière laissent peu d’espace disponible. Enfin, la fixation d’un tel enrouleur à proximité immédiate d’une telle coupelle est complexe puisqu’il convient de laisser un accès pour la dépose et/ou la pose d’un tel amortisseur arrière. Such a reel and such a return therefore need to be rigidly fixed. However, the location of such a reference is immutable. In addition, a reel support crossed by the belt strap weakens the attachment of such a reel. These rigidity constraints are particularly complex to satisfy behind a second or rear row of an already heavily congested vehicle. In particular, a mounting cup for a rear shock absorber, behind such a second row as well as an extreme rear foot coming close to such a rear row leave little space available. Finally, fixing such a retractor in the immediate vicinity of such a cup is complex since it is necessary to leave access for the removal and/or installation of such a rear shock absorber.
Présentation de l'invention Presentation of the invention
La présente invention vise à fournir un agencement remédiant aux inconvénients ci-dessus. En particulier, l’invention permet de renforcer un pied arrière au niveau d’un renvoi de sorte à transmettre les efforts reçus par un tel renvoi au niveau d’un soubassement d’un tel véhicule, tout en satisfaisant les contraintes d’emplacement de la sangle imposées par la réglementation. The present invention aims to provide an arrangement remedying the above drawbacks. In particular, the invention makes it possible to reinforce a rear leg at the level of a return so as to transmit the forces received by such a return to the level of a base of such a vehicle, while satisfying the location constraints of the strap imposed by the regulations.

Description détaillée detailed description
La direction selon laquelle un véhicule, notamment un véhicule automobile, se déplace en ligne droite est définie comme étant la direction longitudinale X. Par convention, la direction perpendiculaire à la direction longitudinale, située dans un plan parallèle au sol, est nommée direction transversale Y. La troisième direction, perpendiculaire aux deux autres, est nommée direction verticale Z. Ainsi, on utilise un repère direct XYZ dans lequel X est la direction longitudinale dans le sens avant-arrière du véhicule, donc dirigée vers l’arrière, Y est la direction transversale dirigée vers la droite et Z est la direction verticale dirigée vers le haut. Le sens avant correspond au sens dans lequel le véhicule se déplace habituellement dans la direction longitudinale et est opposé au sens arrière. The direction in which a vehicle, in particular a motor vehicle, moves in a straight line is defined as the longitudinal direction X. By convention, the direction perpendicular to the longitudinal direction, located in a plane parallel to the ground, is called transverse direction Y The third direction, perpendicular to the other two, is called vertical direction Z. Thus, we use a direct reference XYZ in which X is the longitudinal direction in the front-rear direction of the vehicle, therefore directed towards the rear, Y is the. transverse direction directed to the right and Z is the vertical direction directed upwards. The forward direction is the direction in which the vehicle usually travels in the longitudinal direction and is opposite to the reverse direction.
Comme illustré sur la figure 1 , un véhicule, par exemple un véhicule automobile 1 , comprend une caisse 6. Le véhicule comprend un premier rang 7 de siège(s) et/ou une banquette. Le véhicule comprend de préférence un deuxième rang 5. Le deuxième rang 5 comprend un dossier 8 d’un siège ou d’une banquette. Le véhicule ou la caisse 6 comprend un agencement 3.

De préférence, l’enrouleur 20 comprend un moyen de blocage ou de limitation (non illustré) apte à bloquer le déroulement de la sangle 2 en cas d’effort sur la sangle, par exemple en cas de freinage ou de choc du véhicule. Plus précisément, comme illustré sur la figure 3, l’agencement 3 comprend le support 10 pour la fixation de l’enrouleur 20 (illustré en pointillés) de la sangle 2 de ceinture de sécurité. L’agencement 3 comprend encore un pied arrière 36 ou pied extrême arrière ou portion latérale d’anneau de coffre. L’agencement 3 comprend encore une coupelle 33 pour la fixation d’un amortisseur (non illustré).

L’agencement 3 comprend encore un moyen de rigidification 50 du support 10 et/ou du pied arrière 36. Le moyen de rigidification 50 permet de renforcer le support 10 et/ou le pied arrière 36 lors des sollicitations sur la sangle 2 de ceinture de sécurité. As illustrated in Figure 1, a vehicle, for example a motor vehicle 1, comprises a body 6. The vehicle comprises a first row 7 of seat(s) and/or a bench seat. The vehicle preferably comprises a second row 5. The second row 5 comprises a backrest 8 of a seat or a bench. The vehicle or body 6 comprises an arrangement 3. The vehicle, or the body, or the arrangement comprises at least one support 10, illustrated in particular in Figure 2. The vehicle, or the arrangement, comprises at least one device for seat belt, for example at each seat in the vehicle. A seat belt device comprises in particular a reel 20 and a strap 2. Preferably, the reel 20 comprises a blocking or limiting means (not illustrated) capable of blocking the unwinding of the strap 2 in the event of force on the strap, for example in the event of braking or vehicle impact. More precisely, as illustrated in Figure 3, the arrangement 3 comprises the support 10 for fixing the reel 20 (illustrated in dotted lines) of the seat belt strap 2. Arrangement 3 also includes a rear foot 36 or extreme rear foot or side portion of the trunk ring. Arrangement 3 also includes a cup 33 for fixing a shock absorber (not illustrated). Arrangement 3 also includes an extension 32 for the cup 33, so as to fix the cup 33 further in height. The arrangement 3 also includes a means of stiffening 50 of the support 10 and/or the rear foot 36. The stiffening means 50 makes it possible to reinforce the support 10 and/or the rear foot 36 during stresses on the strap 2 of the belt. security.
De préférence, comme illustré sur les figures 2 et 3, l’agencement 3 comprend un renvoi 9 pour la sangle 2 de la ceinture de sécurité. Le renvoi 9 est fixé par exemple intégralement sur le pied arrière 36. Par exemple, deux vis 69 coopérant avec des écrous rapportés ou taraudages ménagés sur le pied arrière 36 sont prévues pour assurer cette fixation. Alternativement, un crochet coopérant avec une lumière ou un trou et un système vis écrou, ou encore un ou au moins trois systèmes vis-écrous sont prévus pour assurer la fixation du renvoi 9 sur le pied arrière 36. Preferably, as illustrated in Figures 2 and 3, the arrangement 3 comprises a reference 9 for the strap 2 of the seat belt. The reference 9 is fixed for example entirely on the rear foot 36. For example, two screws 69 cooperating with added nuts or threads provided on the rear foot 36 are provided to ensure this fixing. Alternatively, a hook cooperating with a light or a hole and a screw-nut system, or one or at least three screw-nut systems are provided to ensure the fixing of the return 9 on the rear foot 36.
Comme illustré sur la figure 3, le renvoi 9 peut être fixé partiellement sur le pied arrière 36. Par exemple, la caisse 6, ou l’agencement 3, comprend une doublure de custode 31 . Dans ce cas, de préférence, le renvoi est fixé d’une part sur le pied arrière 36 et d’autre part sur la doublure de custode 31 agencée à proximité du pied arrière. Par exemple une vis 69 vient coopérer au niveau du pied arrière 36 et une autre vis 69 vient coopérer au niveau de la doublure de custode 31 . De préférence, le renvoi 9 s’étend, ou s’étend sensiblement, au-dessus du support 10 selon la direction verticale. Dans le mode de réalisation illustré, le support 10 de l’enrouleur 20 comprend une ouverture 15. L’ouverture 15, de type orifice ou fente, offre un passage pour la sangle 2. Ainsi, la sangle 2 s’étend depuis l’enrouleur 20, traverse l’ouverture 15 du support 10, passe sur le renvoi 9 de sorte à être guidée dans des zones recherchées satisfaisants des contraintes en termes de sécurité et/ou d’ergonomie. De préférence, une extrémité de la sangle 2 demeure fixée au sein de l’enrouleur et l’autre extrémité est fixée au niveau d’une assise de siège correspondante. As illustrated in Figure 3, the return 9 can be partially fixed on the rear leg 36. For example, the body 6, or the arrangement 3, includes a rear quarter lining 31. In this case, preferably, the return is fixed on the one hand on the rear leg 36 and on the other hand on the rear quarter lining 31 arranged near the rear leg. For example, a screw 69 cooperates at the rear foot 36 and another screw 69 cooperates at the rear quarter lining 31. Preferably, the reference 9 extends, or extends substantially, above the support 10 in the vertical direction. In the illustrated embodiment, the support 10 of the reel 20 comprises an opening 15. The opening 15, of the orifice or slot type, offers a passage for the strap 2. Thus, the strap 2 extends from the reel 20, passes through the opening 15 of the support 10, passes over the return 9 so as to be guided into desired areas satisfying constraints in terms of safety and/or ergonomics. Preferably, one end of the strap 2 remains fixed within the reel and the other end is fixed at the level of a corresponding seat base.
Avantageusement, comme illustré au niveau de la caisse 6 illustrée partiellement sur la figure 4, le moyen de rigid ification 50 est un renfort 51 . Advantageously, as illustrated at the level of the body 6 partially illustrated in Figure 4, the stiffening means 50 is a reinforcement 51.
Dans un mode de réalisation non illustré, le renfort 51 est fixé sur le pied arrière 36 et sur la réhausse 32, de préférence par soudage, notamment par soudage par points. In an embodiment not illustrated, the reinforcement 51 is fixed on the rear leg 36 and on the extension 32, preferably by welding, in particular by spot welding.
Dans un autre mode de réalisation non illustré, le renfort 51 est fixé sur le pied arrière 36 et sur le support 10, de préférence par soudage, notamment par soudage par points. In another embodiment not illustrated, the reinforcement 51 is fixed on the rear leg 36 and on the support 10, preferably by welding, in particular by spot welding.
Dans un autre mode de réalisation non illustré, le renfort 51 est fixé sur le pied arrière 36, sur la réhausse 32 et sur le support 10, de préférence par soudage, notamment par soudage par points. In another embodiment not illustrated, the reinforcement 51 is fixed on the rear leg 36, on the extension 32 and on the support 10, preferably by welding, in particular by spot welding.
Avantageusement, comme illustré sur la figure 4 notamment, le renfort 51 est fixé sur le pied arrière 36, sur la réhausse 32, sur le support 10, et sur la coupelle 33, de préférence par soudage, notamment par soudage par points. Dans ce cas, des points de soudure 60 sont pratiqués entre le renfort 51 et le pied arrière 36, entre le renfort 51 et le support 10, entre le renfort 51 et la réhausse 32 et entre le renfort 51 et la coupelle 33. Par exemple, un seul point de soudure est prévu entre le renfort 51 et la coupelle 33. Par exemple, un seul point de soudure est prévu entre le renfort 51 et la réhausse 32. Davantage de points de soudure peuvent être prévus à ce niveau. Bien que six points de soudure sont illustrés entre le support 10 d’enrouleur et le renfort 51 , davantage ou moins de points de soudure peuvent être prévus. Par exemple, deux points de soudure sont prévus entre le renfort 51 et le pied arrière 36. Un seul point ou davantage de points de soudure peuvent être prévus à ce niveau. Advantageously, as illustrated in Figure 4 in particular, the reinforcement 51 is fixed on the rear foot 36, on the extension 32, on the support 10, and on the cup 33, preferably by welding, in particular by spot welding. In this case, welding points 60 are made between the reinforcement 51 and the rear leg 36, between the reinforcement 51 and the support 10, between the reinforcement 51 and the extension 32 and between the reinforcement 51 and the cup 33. For example , a single welding point is provided between the reinforcement 51 and the cup 33. For example, a single welding point is provided between the reinforcement 51 and the extension 32. More welding points can be provided at this level. Although six weld points are illustrated between the reel support 10 and the reinforcement 51, more or fewer weld points may be provided. For example, two welding points are provided between the reinforcement 51 and the rear leg 36. A single point or more welding points can be provided at this level.
A noter que un ou plusieurs cordons de soudure peuvent remplacer une série de points de soudure, voire l’intégralité des points de soudure. Note that one or more weld beads can replace a series of weld points, or even all of the weld points.
Comme illustré en particulier sur les figures 5 et 6, le renfort 51 comprend un bord tombé 56. Le bord tombé 56 facilite la fixation, en particulier par soudage, avec le support 10. De préférence, le renfort 51 comprend un trou ou orifice 55. Avantageusement, le renfort 51 comprend des bords tombés 54, notamment au niveau du périmètre du trou 55. As illustrated in particular in Figures 5 and 6, the reinforcement 51 comprises a fallen edge 56. The fallen edge 56 facilitates fixing, in particular by welding, with the support 10. Preferably, the reinforcement 51 comprises a hole or orifice 55 Advantageously, the reinforcement 51 comprises fallen edges 54, in particular at the perimeter of the hole 55.
Par exemple, le renfort 51 comprend un trou oblong 52. Le trou oblong 52 sert par exemple à la fixation d’un habillage de custode. Par exemple, le renfort 51 comprend un trou circulaire 53. Le trou circulaire 53 sert par exemple au procédé de tôlerie, par exemple en termes de positionnement et/ou centrage. Le renfort 51 peut comprendre d’autres trous pour d’éventuelles fixations si besoin. For example, the reinforcement 51 includes an oblong hole 52. The oblong hole 52 is used for example to attach a rear quarter panel. For example, the reinforcement 51 comprises a circular hole 53. The circular hole 53 is used for example in the sheet metal process, for example in terms of positioning and/or centering. The reinforcement 51 may include other holes for possible fixings if necessary.
Comme illustré en particulier sur la figure 3, l’agencement 3 comprend de préférence l’enrouleur 20 pour la sangle 2 de ceinture de sécurité. De préférence, le support 10 comprend une face de réception 13 agencée sensiblement dans un plan vertical et transversal, la face de réception 13 étant orientée vers l’arrière. Ainsi, l’enrouleur 20 est fixé sur, ou au niveau de la face de réception 13 orientée vers l’arrière. Le support 10 comprend une face 18, opposée à la face de réception 13 du support 10, la face 18 étant orientée vers l’avant du véhicule. Par exemple, comme illustré sur la figure 4, le support 10 comprend un moyen de verrouillage du dossier 8 en position, par exemple de type anneau 41 . Un orifice 42 ménagé au sein du support 10 permet le passage de l’anneau 41 de sorte qu’il s’étende vers l’avant tout en étant fixé au niveau de la face de réception 13 orientée vers l’arrière du véhicule. As illustrated in particular in Figure 3, the arrangement 3 preferably comprises the reel 20 for the seat belt strap 2. Preferably, the support 10 comprises a receiving face 13 arranged substantially in a vertical and transverse plane, the receiving face 13 being oriented towards the rear. Thus, the reel 20 is fixed on, or at the level of the receiving face 13 oriented towards the rear. The support 10 comprises a face 18, opposite the receiving face 13 of the support 10, the face 18 being oriented towards the front of the vehicle. For example, as illustrated in Figure 4, the support 10 comprises a means for locking the backrest 8 in position, for example of the ring type 41. An orifice 42 provided within the support 10 allows the passage of the ring 41 so that it extends towards the front while being fixed at the level of the receiving face 13 oriented towards the rear of the vehicle.
De préférence, l’agencement 3 comprend un passage de roue structurel 34. Preferably, arrangement 3 includes a structural wheel arch 34.
De préférence, le support 10 est fixé sur la doublure de custode 31 , de préférence par soudage, notamment par soudage par points. De préférence encore, le support 10 est encore fixé sur le pied arrière 36 et/ou sur le passage de roue structurel 34, de préférence par soudage, notamment par soudage par points. Pour cela, de préférence, le support 10 comprend des bords tombés 14, sur au moins une partie, voire sur l’intégralité du périmètre externe su support 10. Preferably, the support 10 is fixed to the rear quarter lining 31, preferably by welding, in particular by spot welding. More preferably, the support 10 is still fixed on the rear leg 36 and/or on the structural wheel arch 34, preferably by welding, in particular by spot welding. For this, preferably, the support 10 comprises fallen edges 14, on at least part, or even on the entire external perimeter of the support 10.
En cas de freinage ou de décélération du véhicule, en particulier en cas de choc subi par le véhicule, notamment en cas de choc à l’avant ou au niveau de l’avant, alors que le véhicule est en marche avant, le passager est entraîné vers l’avant. La retenue du passager par la sangle 2 se bloquant en déroulement par la mise en action du moyen de limitation implanté dans l’enrouleur 20 crée une force F sur la sangle illustrée sur la figure 3 et par conséquent sur le renvoi 9. Pour rappel, lorsque le moyen de limitation de la sangle est activé, la sangle est bloquée en déroulement par rapport à l’enrouleur. Autrement dit, l’enrouleur 20 devient un point d’ancrage de l’extrémité de la sangle à ce niveau. Cette force F se répercute en partie en un effort R s’étendant sensiblement verticalement agissant sur l’enrouleur et/ou l’extrémité de la sangle bloquée dans l’enrouleur du fait de l’emplacement du renvoi 9 au-dessus de l’enrouleur 20. En particulier, cet effort F est repris sur le ou les points de fixation du renvoi 9 sur le pied arrière et/ou sur un autre élément de la caisse 6, tel que la doublure de custode 31 par exemple. In the event of braking or deceleration of the vehicle, in particular in the event of an impact suffered by the vehicle, in particular in the event of an impact to the front or at the front, while the vehicle is in forward motion, the passenger is driven forward. The retention of the passenger by the strap 2 being blocked in unwinding by the activation of the limitation means installed in the reel 20 creates a force F on the strap illustrated in Figure 3 and consequently on the return 9. As a reminder, when the strap limitation means is activated, the strap is blocked in unwinding relative to the reel. In other words, the reel 20 becomes an anchoring point for the end of the strap at this level. This force F is partly reflected in a force R extending substantially vertically acting on the reel and/or the end of the strap blocked in the reel due to the location of the return 9 above the reel 20. In particular, this force F is taken up on the fixing point(s) of the return 9 on the foot rear and/or on another element of the body 6, such as the rear quarter lining 31 for example.
Ainsi, l’effort R tend à déplacer vers le haut l’enrouleur 20, notamment à plier son support 10 au niveau de l’ouverture 15 qui crée une fragilité dans le support. L’effort F tend à plier le pied arrière selon une direction perpendiculaire ou sensiblement perpendiculaire à la direction D selon laquelle le pied arrière s’étend. Thus, the force R tends to move the reel 20 upwards, in particular to bend its support 10 at the level of the opening 15 which creates fragility in the support. The force F tends to bend the rear foot in a direction perpendicular or substantially perpendicular to the direction D in which the rear foot extends.
Grâce à la solution, malgré l’effort F agissant sur la sangle 2 du fait de l’actionnement du moyen de limitation du déroulement de la sangle bloquant la sangle, le support 10 conserve sa forme. En effet, le moyen de rigidification 50, notamment de type renfort 51 , rigidifie le support 10. Bien que le support soit muni de l’ouverture 15 pour le passage de la sangle 2, le support ne se plie pas. En outre, le renfort 51 maintient le pied arrière 36, l’empêche de s’affaisser sous l’effet de la force F agissant sur le renvoi 9 fixé sur le pied arrière. Pour rappel, le renfort 51 comprend des bords tombés 54, 56 lui offrant une grande rigidité. Les points de soudure fixant le renfort 51 sur plusieurs éléments tels que le pied arrière 36 et/ou le support 10 et/ou la réhausse 32 et/ou la coupelle 33 participent à la rigidité de l’ensemble. Le cas échéant, la ligne de points de soudure permet de bloquer les déplacements et déformations du support 10. Cette ligne de points crée une liaison entre le pied extrême arrière et la réhausse de coupelle. Notamment, le renfort 51 fixé d’une part sur le pied arrière 36 et d’autre part sur la réhausse et/ou sur la coupelle et/ou sur le support 10 lui-même fixé sur le passage de roue structurel 34 permet de lier le pied arrière au soubassement. Autrement dit, le renfort 51 assure une transmission d’efforts depuis le pied arrière vers le soubassement particulièrement rigide. Thanks to the solution, despite the force F acting on the strap 2 due to the actuation of the means for limiting the unwinding of the strap blocking the strap, the support 10 retains its shape. Indeed, the stiffening means 50, in particular of the reinforcement type 51, stiffens the support 10. Although the support is provided with the opening 15 for the passage of the strap 2, the support does not fold. In addition, the reinforcement 51 maintains the rear leg 36 and prevents it from collapsing under the effect of the force F acting on the return 9 fixed on the rear leg. As a reminder, the reinforcement 51 includes fallen edges 54, 56 giving it great rigidity. The welding points fixing the reinforcement 51 on several elements such as the rear leg 36 and/or the support 10 and/or the extension 32 and/or the cup 33 contribute to the rigidity of the assembly. If necessary, the line of welding points makes it possible to block the movements and deformations of the support 10. This line of points creates a connection between the extreme rear leg and the cup extension. In particular, the reinforcement 51 fixed on the one hand on the rear leg 36 and on the other hand on the extension and/or on the cup and/or on the support 10 itself fixed on the structural wheel arch 34 makes it possible to link the rear foot to the base. In other words, reinforcement 51 ensures transmission of forces from the rear foot to the particularly rigid base.
Les bords tombés 54 du renfort 51 permettent en outre d’augmenter l’efficacité en termes de renforcement du pied arrière et/ou du support 10. L’ouverture 55 du renfort 51 permet de diminuer la masse du renfort tout en évitant une surface plane sur le renfort susceptible de créer de la résonance. The fallen edges 54 of the reinforcement 51 also make it possible to increase the effectiveness in terms of reinforcing the rear foot and/or the support 10. The opening 55 of the reinforcement 51 makes it possible to reduce the mass of the reinforcement while avoiding a flat surface on the reinforcement likely to create resonance.
En résumé, la solution porte sur un renfort de structure entre le pied extrême arrière, le support d’enrouleur de ceinture et la réhausse de coupelle de fixation d’un amortisseur arrière. In summary, the solution concerns a structural reinforcement between the extreme rear foot, the belt retractor support and the rear shock absorber mounting cup extension.
La solution est compatible avec le manque d'espace entre le pied extrême arrière (par exemple incliné de l’ordre de 45 degrés) et la banquette ou siège de rang arrière ainsi que le positionnement vertical de l'enrouleur de sangle de ceinture. La solution rend possible la fixation du renvoi de type « fil » de sangle de ceinture de sécurité sur le pied arrière bien que celui- ci reçoive les efforts directement en cas de choc comme évoqué précédemment, en particulier reçoive des efforts normaux ou sensiblement normaux à la direction suivant laquelle s’étend ce pied arrière. The solution is compatible with the lack of space between the extreme rear foot (for example inclined at around 45 degrees) and the rear bench or seat as well as the vertical positioning of the belt strap retractor. The solution makes it possible to fix the “wire” type seat belt strap return on the rear foot although the latter receives the forces directly in the event of an impact as mentioned previously, in particular receives normal or substantially normal forces at the direction in which this rear foot extends.
La solution permet d’utiliser un support d’enrouleur traversé par la sangle et agencé verticalement grâce à la rigidité apportée par le renfort. The solution allows the use of a reel support crossed by the strap and arranged vertically thanks to the rigidity provided by the reinforcement.
Comme évoqué, l’agencement 3 permet de transmettre les efforts vus par le pied arrière au soubassement et bloquer les déplacements et déformations du support 10 de type tablette. As mentioned, arrangement 3 makes it possible to transmit the forces seen by the rear foot to the base and block the movements and deformations of the tablet-type support 10.
En outre, la solution permet une homogénéité de l'épaisseur et de la composition de la matière utilisée, notamment en ce qui concerne le support 10, un éventuel renfort pour la fixation de l’anneau 41 du dossier 8 sur le support 10 (de préférence une plaque fixée sur la face de réception 13 du support 10) et le renfort 51. Par exemple, la matière est de l’acier et l’épaisseur est de 1 .2 mm. Une telle homogénéité permet des économies en termes d’achat de matière et/ou de gestion de stock de matière. De plus, l’utilisation de matière similaire voire identique, et d’épaisseur similaire voire identique, facilitent grandement le processus de soudage de ces pièces. Il en résulte un soudage particulièrement fiable et durable. In addition, the solution allows homogeneity of the thickness and composition of the material used, in particular with regard to the support 10, a possible reinforcement for fixing the ring 41 of the backrest 8 on the support 10 (of preferably a plate fixed on the receiving face 13 of the support 10) and the reinforcement 51. For example, the material is steel and the thickness is 1.2 mm. Such homogeneity allows savings in terms of purchasing materials and/or managing stock of materials. In addition, the use of similar or even identical material, and thickness similar or even identical, greatly facilitate the welding process of these parts. The result is particularly reliable and durable welding.
A noter que l’amélioration de la rigidité de cette zone arrière au niveau de la coupelle de réception d’un amortisseur, ainsi « fermée » par le renfort 51 , permet d’améliorer l'acoustique. Cela concourt à augmenter le confort au sein du véhicule ainsi que la qualité perçue du véhicule. Note that improving the rigidity of this rear zone at the level of the shock absorber receiving cup, thus “closed” by the reinforcement 51, makes it possible to improve the acoustics. This helps to increase comfort within the vehicle as well as the perceived quality of the vehicle.
La solution permet de concilier l’esthétique du véhicule doté d’un pied arrière fortement incliné, de s’intégrer dans le faible encombrement disponible à ce niveau et de satisfaire les réglementations, notamment en termes de prestations de sécurités passives. The solution makes it possible to reconcile the aesthetics of the vehicle with a strongly inclined rear foot, to fit into the small footprint available at this level and to satisfy regulations, particularly in terms of passive safety services.
La solution offre une fixation d’enrouleur et du renvoi correspondant particulièrement rigide. Les efforts provenant de la sangle de ceinture de sécurité en cas de freinage puissant et/ou de choc sont répartis sur différents éléments de la caisse notamment. Bien que le renvoi ne puisse pas être placé ailleurs étant donné l’implantation de l’enrouleur de sangle, le support du renvoi, à savoir le pied arrière est rigide. Malgré la présence de la coupelle de fixation d’un amortisseur arrière derrière le second rang ainsi qu’un pied extrême arrière venant à proximité du rang arrière laissant peu d’espace disponible, de la présence du support d’enrouleur et du renfort 51 , un accès subsiste pour la dépose et/ou la pose de l’amortisseur arrière. The solution offers a particularly rigid reel attachment and corresponding return. The forces coming from the seat belt strap in the event of strong braking and/or impact are distributed over different elements of the body in particular. Although the return cannot be placed elsewhere given the location of the strap winder, the support for the return, namely the rear foot, is rigid. Despite the presence of the mounting cup for a rear shock absorber behind the second row as well as an extreme rear foot coming close to the rear row leaving little space available, the presence of the reel support and the reinforcement 51, Access remains for removing and/or installing the rear shock absorber.
En outre, la solution est compatible avec un enrouleur de sangle standard dans un environnement exigu et les contraintes en termes de sécurité passive sont satisfaites, en particulier grâce à l’emplacement du fil de renvoi 9. In addition, the solution is compatible with a standard strap winder in a confined environment and the constraints in terms of passive safety are satisfied, in particular thanks to the location of the return wire 9.
Bien que la solution ait été illustrée au niveau d’un dispositif de ceinture de sécurité agencé au niveau d’une place arrière gauche, elle peut évidemment être transposée à une place arrière droite. Eventuellement, la solution peut être adaptée à un dispositif de ceinture de sécurité pour une place avant d’un véhicule. Notamment la solution peut être adaptée à un dispositif de ceinture de sécurité pour une place avant d’un véhicule ne disposant que de places avant. Although the solution has been illustrated at the level of a seat belt device arranged at the level of a left rear seat, it can obviously be transposed to a right rear seat. Optionally, the solution can be adapted to a seat belt device for a front seat of a vehicle. In particular, the solution can be adapted to a seat belt device for a front seat of a vehicle having only front seats.
En remarque, la solution atteint donc l’objectif recherché de fournir un agencement permettant de fixer rigidement un support d’enrouleur de ceinture de sécurité ainsi qu’un renvoi de la sangle tout en satisfaisant les contraintes d’emplacement de la sangle imposées par la réglementation, et présente l’avantage de pouvoir être utilisé sur d’autres types de véhicules, à savoir des camions, bus, cars voire des aéronefs. As a side note, the solution therefore achieves the desired objective of providing an arrangement making it possible to rigidly fix a seat belt retractor support as well as a strap return while satisfying the strap location constraints imposed by the regulations, and has the advantage of being able to be used on other types of vehicles, namely trucks, buses, coaches and even aircraft.
