Description

DISPOSITIF DE RETENUE LATERALE D'UN OCCUPANT DE
SIEGE DE VEHICULE AUTOMOBILE
L'invention concerne un dispositif de retenue latérale d'un occupant de siège de véhicule automobile dans lequel un support est disposé le long d'un flanc latéral d'un coussin d'assise et porte un moyen de montage à rotation dudit support sur un élément de châssis du coussin d'assise à proximité du bord arrière dudit coussin.DEVICE FOR LATERAL RETENTION OF AN OCCUPANT OF
MOTOR VEHICLE SEAT
The invention relates to a device for lateral restraint of an occupant of a motor vehicle seat in which a support is arranged along a lateral flank of a seat cushion and carries a means for rotationally mounting said support on a frame element of the seat cushion near the rear edge of said cushion.

La publication US-A-4810035 décrit un dispositif qui assure le maintien latéral du bassin de l'occupant du siège et qui est susceptible d'occuper une position de repos relevée dans le but de faciliter la montée et la descente de l'utilisateur du siège.The publication US-A-4810035 describes a device which provides lateral support for the pelvis of the seat occupant and which is capable of occupying a raised rest position in order to facilitate the ascent and descent of the user of the seat. seat.

Lorsque le véhicule est soumis à un choc latéral il importe de protéger l'occupant d'un siège des forces d'impact au contact de la paroi latérale de l'habitacle. On a ainsi proposé des dispositifs de rembourrage et de protection.When the vehicle is subjected to a side impact, it is important to protect the occupant of a seat from impact forces in contact with the side wall of the passenger compartment. Padding and protection devices have thus been proposed.

La publication FR-A-2346186 décrit un rembourrage composite en deux parties dont l'une constitue un corps peu déformable tandis que l'autre est un corps cellulaire souple.The publication FR-A-2346186 describes a composite padding in two parts, one of which constitutes a slightly deformable body while the other is a flexible cellular body.

La publication FR-A-2650544 décrit un dispositif de protection mobile entre une position de repos, dans laquelle le dispositif est immobilisé, et une position de service dans laquelle le dispositif est introduit dans l'habitacle consécutivement à la mise en oeuvre d'un actionneur.The publication FR-A-2650544 describes a mobile protection device between a rest position, in which the device is immobilized, and a service position in which the device is introduced into the passenger compartment following the use of a actuator.

Ces dispositifs sont intégrés à une paroi latérale du véhicule et réduisent dans une certaine mesure l'habitabilité intérieure de l'habitacle.These devices are integrated into a side wall of the vehicle and to a certain extent reduce the interior habitability of the passenger compartment.

L'invention a pour objet un dispositif de retenue et de protection escamotable, du type comportant un support amortisseur monté à rotation sur un élément de châssis du coussin d'assise et qui occupe une position latérale escamotée lorsque le siège est inoccupé et une position latérale érigée en position d'utilisation du siège. The subject of the invention is a retractable protection and restraint device, of the type comprising a damping support rotatably mounted on a frame element of the seat cushion and which occupies a retracted lateral position when the seat is unoccupied and a lateral position erected in seat use position.

Selon l'invention le support porte l'ancrage de la tige d'actionnement d'un vérin articulé sur l'élément de châssis et l'ancrage de ladite tige est longitudinalement décalé vers la partie antérieure dudit châssis par rapport à l'axe d'articulation dudit support sur cet élément de châssis du siège.According to the invention, the support carries the anchoring of the actuating rod of a jack articulated on the chassis element and the anchoring of said rod is longitudinally offset towards the front part of said chassis relative to the axis d articulation of said support on this seat frame element.

Le dispositif de retenue ainsi réalisé est notamment destiné à protéger latéralement l'occupant d'un siège et peut de ce fait être actionné par un contact de présence intégré au coussin du siège ou à une porte du véhicule.The restraint device thus produced is in particular intended to laterally protect the occupant of a seat and can therefore be actuated by a presence contact integrated in the seat cushion or in a vehicle door.

Le dispositif de retenue précité présente en outre l'avantage d'être intégré au siège et d'être monté à mobilité conjointement avec ledit siège.The aforementioned retaining device also has the advantage of being integrated into the seat and of being mounted for mobility together with said seat.

Le dispositif de retenue facilite par conséquent l'implantation dans un véhicule à porte latérale conventionnelle, des sièges réglables comportant un boîtier de commande latéral.The retaining device therefore facilitates the installation in a vehicle with a conventional side door, adjustable seats comprising a lateral control unit.

D'autres caractéristiques et avantages de l'invention apparaîtront à la lecture de la description d'un exemple de réalisation du dispositif en référence au dessin annexé dans lequel - les figures 1 et 2 sont des représentations perspectives d'un siège de
véhicule équipé du dispositif de retenue conforme à l'invention,
respectivement dans les positions de repos et d'utilisation dudit
dispositif.Other characteristics and advantages of the invention will appear on reading the description of an exemplary embodiment of the device with reference to the appended drawing in which - Figures 1 and 2 are perspective representations of a seat of
vehicle fitted with the restraint device according to the invention,
respectively in the rest and use positions of said
device.

- la figure 3 est une vue en élévation du soubassement du siège sans son
boîtier de protection et montrant l'implantation du vérin de commande
du dispositif de retenue.- Figure 3 is an elevational view of the seat base without sound
protective case and showing the location of the control cylinder
of the retainer.

- la figure 4 est une vue en coupe transversale du siège selon la ligne W-
IV de la figure 3.- Figure 4 is a cross-sectional view of the seat along line W-
IV of Figure 3.

- la figure 5 est une vue en coupe transversale de l'implantation du vérin
de commande du dispositif de retenue selon la ligne V-V de la figure 3.- Figure 5 is a cross-sectional view of the location of the jack
control device according to line VV of figure 3.

Le siège 1 représenté au dessin comporte de manière conventionnelle un coussin d'assise 10 et un dossier 1 1 articulé autour d'un axe 12 porté par un élément de châssis 13 du coussin 10. Le coussin d'assise 10 et le dossier 11 sont ici représentés conventionnellement en traits mixtes.The seat 1 shown in the drawing conventionally comprises a seat cushion 10 and a backrest 11 articulated around an axis 12 carried by a frame element 13 of the cushion 10. The seat cushion 10 and the backrest 11 are here conventionally represented in dashed lines.

Le châssis 13 est revêtu extérieurement par un carter protecteur 14 sur lequel est monté le boîtier de protection 15 et dont une paroi latérale 16 limite transversalement le logement 17 du support 20 de retenue du passager occupant le siège 1.The chassis 13 is coated on the outside by a protective casing 14 on which the protective housing 15 is mounted and a side wall 16 of which transversely limits the housing 17 of the support 20 for retaining the passenger occupying the seat 1.

Ainsi que cela est montré aux figures 3 et 5, le support 20 est disposé le long du flanc latéral du coussin d'assise 10 et porte un axe de montage 21 solidaire de l'élément de châssis 13 à proximité du bord arrière dudit coussin 10.As shown in Figures 3 and 5, the support 20 is disposed along the lateral flank of the seat cushion 10 and carries a mounting pin 21 integral with the chassis element 13 near the rear edge of said cushion 10 .

Selon une caractéristique de l'invention, le support 20 porte également l'ancrage 22 de la tige d'actionnement 23 d'un vérin électrique de commande 25.According to a characteristic of the invention, the support 20 also carries the anchor 22 of the actuating rod 23 of an electric control cylinder 25.

Selon une autre caractéristiques de l'invention l'ancrage 22 est longitudinalement décalé vers la partie antérieure du châssis 13, par rapport à l'axe de montage et d'articulation 21 du support 20.According to another characteristic of the invention, the anchor 22 is longitudinally offset towards the front part of the chassis 13, with respect to the mounting and articulation axis 21 of the support 20.

Une telle mesure constructive autorise le rangement du support 20 dans le logement 17 limité transversalement par la paroi 16 du boîtier 15. Ainsi que cela est représenté à la figure 5, la paroi 16 est agrafée sur l'élément de châssis 13 et ce dernier supporte ainsi que cela est représenté à la figure 4 un profil de montage 26 de l'axe d'articulation 21 du support 20 et de l'axe d'articulation 27 du vérin 25.Such a constructive measure allows the storage of the support 20 in the housing 17 limited transversely by the wall 16 of the housing 15. As shown in FIG. 5, the wall 16 is stapled to the chassis element 13 and the latter supports as shown in FIG. 4, a mounting profile 26 of the hinge pin 21 of the support 20 and of the hinge pin 27 of the jack 25.

L'agencement précité permet d'associer le boîtier 15 au carter 14 audessus duquel sont localisés selon une disposition ergonomique satisfaisante, une commande 28 de réglage longitudinal du siège le long de glissières 31 représentées à la figure 5, une commande de réglage 29 de la hauteur du coussin d'assise 10 et une commande 30 d'inclinaison du dossier 11.The above arrangement allows the housing 15 to be associated with the casing 14 above which are located in a satisfactory ergonomic arrangement, a control 28 for longitudinal adjustment of the seat along slideways 31 shown in FIG. 5, an adjustment control 29 for the height of the seat cushion 10 and a backrest tilt control 30.

Le dispositif de retenue latérale tel que décrit en référence au dessin est encastré sous le panneau d'habillage intérieur 32 de la porte du véhicule et est localisé plus particulièrement dans la zone du point H défini par la trace de l'axe théorique de rotation existant entre les jambes et le torse d'un mannequin représentatif du corps humain utilisé habituellement dans les processus d'essai de sièges.The lateral retaining device as described with reference to the drawing is embedded under the interior trim panel 32 of the vehicle door and is located more particularly in the area of point H defined by the trace of the existing theoretical axis of rotation between the legs and the torso of a mannequin representative of the human body usually used in seat testing processes.

Selon une autre caractéristique de l'invention, il importe que le support 20 occupe une position érigée hors du logement 17 sous l'action d'une commande électrique asservie à l'occupation du siège 1. A cet effet le vérin actionneur 25 du support 20 est monté dans un circuit d'alimentation incluant notamment un contact électrique 35 tel qu'un contact à fermeture noyé dans la matelassure du siège dont la fermeture est assurée par suite d'une pression de contact appliquée sur le coussin d'assise 10. According to another characteristic of the invention, it is important that the support 20 occupies a position erected outside the housing 17 under the action of an electric control slaved to the occupation of the seat 1. For this purpose the actuator cylinder 25 of the support 20 is mounted in a supply circuit including in particular an electrical contact 35 such as a closing contact embedded in the padding of the seat, the closing of which is ensured by contact pressure applied to the seat cushion 10.
