Abstract
(EN)
An air bag where a vent hole is closed or has a small opening until a crew plunges into the air bag and the vent hole is opened or has a large opening when a crew plunges into the air bag. An air bag system is also provided. Interior of the air bag (10) is sectioned by inner panels (22A, 22B) into a central first chamber (1), and a second chamber surrounding the first chamber (1). A rear panel (14) is provided with a vent hole (18) for allowing communication between the second chamber (2) and the outside of the air bag. A lid member (60) is provided to cover the vent hole (18) from the inside of the rear panel (14). A tether (connection member) (70) couples the lid member (60) with the inner panels (22A, 22B). When the air bag (10) expands, the tether (70) is strained to block movement of the lid member (60) to the outside of the air bag (10).

L'invention concerne un coussin de sécurité gonflable dans lequel un trou d'aération est fermé ou ne présente qu'une petite ouverture jusqu'à ce qu'un occupant entre en contact avec le coussin de sécurité gonflable et dans lequel le trou d'aération est ouvert ou présente une grande ouverture lorsqu'un occupant entre en contact avec le coussin de sécurité gonflable. L'invention concerne aussi un système de coussin de sécurité gonflable. L'intérieur du coussin de sécurité gonflable (10) est compartimenté par des panneaux intérieurs (22A, 22B) en une première chambre centrale (1) et une seconde chambre entourant la première chambre (1). Un panneau arrière (14) est équipé d'un trou d'aération (18) pour permettre à la seconde chambre (2) de communiquer avec l'extérieur du coussin de sécurité gonflable. Un élément de couvercle (60) est prévu pour couvrir le trou d'aération (18) de l'intérieur du panneau arrière (14). Une longe (élément de liaison) (70) accouple l'élément de couvercle (60) aux panneaux intérieurs (22A, 22B). Quand le coussin de sécurité gonflable (10) se déploie, la longe (70) est fortement tendue pour bloquer le mouvement de l'élément de couvercle (60) vers l'extérieur du coussin de sécurité gonflable (10).

 エアバッグに乗員が突っ込んで来るまではベントホールが閉又は小開度となっており、エアバッグに乗員が突っ込むとベントホールが開又は大開度となるエアバッグ及びエアバッグ装置。エアバッグ10の内部は、インナーパネル22A,22Bにより、中央の第1室1と、該第1室1を取り囲む第2室とに区画されている。リヤパネル14に、第2室2とエアバッグ外部とを連通するベントホール18が設けられている。リヤパネル14の内側からベントホール18を覆う蓋部材60が設けられている。テザー(繋ぎ部材)70は、蓋部材60とインナーパネル22A,22Bとを連結している。エアバッグ10が膨張した場合、テザー70が緊張し、蓋部材60のエアバッグ10外部側への移動を阻止する。
