Description
La présente description est relative à un dossier de siège de véhicule, notamment de véhicule automobile. Il est également décrit un siège de véhicule comprenant un tel dossier.This description relates to a vehicle seat back, in particular a motor vehicle. A vehicle seat comprising such a backrest is also described.
Dans le domaine automobile, en particulier, il est connu de munir un dossier de siège d’un dispositif de coussin gonflable de sécurité latéral – ci-après dispositif d’airbag latéral. Un tel dispositif est classiquement fixé sur un montant de l’armature du dossier, notamment sur le montant de l’armature de dossier disposé le plus près du centre du véhicule automobile. Un tel dispositif d’airbag latéral vise ainsi à limiter le risque de chocs tête contre tête des occupants de deux sièges disposés transversalement l’un à côté de l’autre dans le véhicule automobile, notamment en cas de choc latéral.In the automotive field, in particular, it is known to provide a seat back with a side airbag device – hereinafter side airbag device. Such a device is conventionally attached to an upright of the backrest frame, in particular to the upright of the backrest frame arranged closest to the center of the motor vehicle. Such a side airbag device thus aims to limit the risk of head-to-head impact of the occupants of two seats arranged transversely one beside the other in the motor vehicle, in particular in the event of a side impact.
Cependant, la fabrication d’un tel siège, comprenant notamment la mise en place d’une matelassure à recouvrir d’une coiffe, rend difficile l’accès à la partie la plus haute de l’armature de dossier, notamment la partie la plus haute des montants de l’armature de dossier. Dans ces conditions, le dispositif d’airbag latéral est souvent fixé relativement bas sur le montant de l’armature de dossier.However, the manufacture of such a seat, comprising in particular the placement of padding to be covered with a cap, makes it difficult to access the highest part of the backrest frame, in particular the most top of the backrest frame uprights. In these conditions, the side airbag device is often fixed relatively low on the upright of the backrest frame.
Il est apparu que du fait de cette fixation relativement basse du dispositif d’airbag latéral, le déploiement du coussin gonflable de sécurité (ou airbag) n’est pas complètement satisfaisant. En effet, le coussin gonflable de sécurité tend à se déployer avec un mouvement présentant une composante transversale, par rapport au véhicule automobile équipé du siège de véhicule. Le coussin gonflable de sécurité se déploie alors trop vers l’intérieur du véhicule, s’éloignant de la position normale de l’occupant sur le siège de véhicule. Par suite, la tête de l’occupant du siège peut être déplacée transversalement de manière relativement importante, avant d’entrer en contact avec le coussin gonflable déployé.It appeared that because of this relatively low mounting of the side airbag device, the deployment of the safety airbag (or airbag) is not completely satisfactory. Indeed, the airbag tends to deploy with a movement having a transverse component, relative to the motor vehicle equipped with the vehicle seat. The air bag will then deploy too far inboard of the vehicle, moving away from the normal occupant position in the vehicle seat. As a result, the head of the seat occupant can be moved transversely to a relatively large extent, before coming into contact with the deployed airbag.
RésuméSummary
La présente description vient améliorer la situation.This description improves the situation.
À cette fin, il est décrit un dossier de siège de véhicule comprenant une armature de dossier avec un montant, le montant étant de préférence destiné à être placé au voisinage du centre du véhicule, et un dispositif de coussin gonflable de sécurité, le dispositif de coussin gonflable de sécurité comprenant au moins un coussin gonflable de sécurité et une sangle fixée au coussin gonflable de sécurité, le dispositif de coussin gonflable de sécurité étant fixé au montant de l’armature de dossier en au moins un premier point de fixation, au moyen d’un dispositif de fixation à tige traversant le montant, la sangle étant fixée à la tige du dispositif de fixation.To this end, there is described a vehicle seat back comprising a back frame with a post, the post preferably being intended to be placed in the vicinity of the center of the vehicle, and an airbag device, the device airbag comprising at least one airbag and a strap attached to the airbag, the airbag device being attached to the post of the backrest frame at at least a first attachment point, by means of a fixing device with a rod passing through the upright, the strap being fixed to the rod of the fixing device.
Ainsi, avantageusement, la sangle permet de forcer un déploiement de l’airbag plus vertical, sans nécessiter un plein accès à la partie de la plus haute de l’armature de dossier pour y installer un nouveau point de fixation du dispositif d’airbag sur l’armature de dossier.Thus, advantageously, the strap makes it possible to force deployment of the airbag more vertically, without requiring full access to the highest part of the backrest frame in order to install there a new attachment point for the airbag device on the backrest frame.
