Abstract
(EN)
[Problem] To minimize injury to a passenger resulting from deployment of a side airbag, even if the passenger is not seated normally. [Solution] An airbag which is a constituent of a side airbag device installed in the vehicle seat according to the present invention is provided with a main chamber (34) which deploys toward the front of a side support portion (12) of the seat, and a sub-chamber (36) which accommodates an inflator (30) and which deploys at a position inward of the main chamber in the width direction of the vehicle. The main chamber is divided, by means of a baffle panel (38), into a main front chamber (34F) at the front, and a main rear chamber (34R) at the rear. The sub-chamber is linked to the main rear chamber at a side in the width direction of the vehicle. When the airbag is deployed, the baffle panel extends along a front edge (36F) of the sub-chamber, as viewed from the width direction of the vehicle. Furthermore, the sub-chamber and the main rear chamber are configured to deploy only inside the side support portion, without bulging out to the outside of the vehicle seat.

[Problème] Réduire au minimum les blessures d'un passager résultant du déploiement d'un coussin de sécurité gonflable latéral, même si le passager n'est pas assis normalement. [Solution] Un coussin de sécurité gonflable, qui est un constituant d'un dispositif de coussin de sécurité gonflable latéral installé dans le siège de véhicule selon la présente invention, est pourvu d'une chambre principale (34) qui se déploie vers l'avant d'une partie support latéral (12) du siège, et d'une sous-chambre (36) qui reçoit un dispositif de gonflage (30) et qui se déploie à un emplacement vers l'intérieur de la chambre principale dans la direction de la largeur du véhicule. La chambre principale est divisée, au moyen d'un panneau déflecteur (38), en une chambre avant principale (34F) à l'avant et une chambre arrière principale (34R) à l'arrière. La sous-chambre est reliée à la chambre arrière principale sur un côté dans la direction de la largeur du véhicule. Lorsque le coussin de sécurité gonflable est déployé, le panneau déflecteur s'étend le long d'un bord avant (36F) de la sous-chambre, vu depuis le sens de la largeur du véhicule. En outre, la sous-chambre et la chambre arrière principale sont conçues pour se déployer uniquement à l'intérieur de la partie support latéral, sans faire saillie vers l'extérieur du siège de véhicule.

【課題】乗員が正常着座していない状況においても、サイドエアバッグの展開によって乗員へ加わるダメージを最小限に抑えること。 【解決手段】本発明の車両用シートに搭載されるサイドエアバッグ装置を構成するエアバッグは、シートのサイドサポート部(12)の前方に向かって展開するメインチャンバ(34)と;インフレータ(30)を収容し、メインチャンバの車幅方向内側で展開するサブチャンバ(36)とを備える。メインチャンバは、バッフルパネル(38)によって、前方のメインフロントチャンバ(34F)と後方のメインリアチャンバ(34R)とに仕切られる。サブチャンバは、車幅方向側部においてメインリアチャンバと連結される。展開時のバッフルパネルは、車幅方向から見たときに、サブチャンバの前縁(36F)に沿って延びる。そして、サブチャンバとメインリアチャンバは、サイドサポート部の内部でのみ展開し、車両用シートの外部に膨出しないように構成される。
