Title
(EN) OCCUPANT RESTRAINT DEVICE
(FR) DISPOSITIF DE RETENUE D'OCCUPANT
(JA) 乗員拘束装置
Abstract
(EN)
Provided is an occupant restraint device that can be expandably deployed in a reliable manner. This occupant restraint device comprises an airbag (3) provided to a side section of a backrest (4) of a vehicle seat, and a tension cloth (2a) that pulls the expandably deploying airbag (3) toward an occupant (P) sitting in the vehicle seat. One end part (21a) of the tension cloth (2a) is held in an interlocking position at the upper part of the backrest (4), another end part (22a) is held in a prescribed location of the vehicle seat, and the tension cloth (2a) is joined by joining parts (23a, 24a) in at least one location on the surface of the airbag (3). When the folded airbag (3) is stored in the vehicle seat, a first distance (L1) along the contour of the backrest (4) between the interlocking position and the joining part (23a) farthest from the interlocking position is shorter than a second distance (L2) along the contour of the backrest (4) from the interlocking position to the rotational center of a shaft (6) that turnably holds the backrest (4).

L'invention concerne un dispositif de retenue d'occupant qui peut être déployé de manière extensible d'une manière fiable. Ce dispositif de retenue d'occupant comprend un coussin de sécurité gonflable (3) prévu sur une section latérale d'un dossier (4) d'un siège de véhicule, et un tissu de tension (2a) qui tire le coussin de sécurité gonflable à déploiement extensible (3) vers un occupant (P) assis sur le siège de véhicule. Une partie d'extrémité (21a) du tissu de tension (2a) est maintenue dans une position de verrouillage au niveau de la partie supérieure du dossier (4), une autre partie d'extrémité (22a) est maintenue dans un emplacement prescrit du siège de véhicule, et le tissu de tension (2a) est relié par des parties de jonction (23a, 24a) dans au moins un emplacement sur la surface du coussin de sécurité gonflable (3). Lorsque le coussin de sécurité gonflable plié (3) est rangé dans le siège de véhicule, une première distance (L1) le long du contour du dossier (4) entre la position de verrouillage et la partie de jonction (23a) la plus éloignée de la position de verrouillage est plus courte qu'une seconde distance (L2) le long du contour du dossier (4) depuis la position de verrouillage jusqu'au centre de rotation d'un arbre (6) qui maintient en rotation le dossier (4).
