Abstract
(EN)
Disclosed are an air bag quickly inflating in the vertical direction and sufficiently inflating in the lateral direction, and an air bag device having the air bag. An inner bag (22) is provided in the air bag (10). The left and right ends of the air bag (10) are connected to the inner bag (22) by tear seams (60). When the air bag (10) is inflated, the lateral inflation of both left and right ends of the air bag (10) to the outer sides is restrained until the internal pressure in the air bag (10) reaches a predetermined value. When the internal pressure in the air bag (10) exceeds the predetermined value, the tear seams (60) are broken, the connection of the left and right ends of the air bag (10) to the inner bag (22) is released, and thereby, both left and right ends of the air bag (10) can be laterally inflated to the outer sides.

La présente invention concerne un airbag gonflant rapidement dans la direction verticale et gonflant suffisamment dans la direction latérale, ainsi qu'un dispositif d'airbag équipé de l'airbag. L'airbag (10) est équipé d'un sac interne (22). Les extrémités gauche et droite de l'airbag (10) sont reliées au sac interne (22) par des coutures déchirables (60). Lorsque l'airbag (10) est gonflé, le gonflage latéral des extrémités gauche et droite de l'airbag (10) sur les côtés externes est contenu jusqu'à ce que la pression interne dans l'airbag (10) atteigne une valeur prédéterminée. Lorsque la pression interne dans l'airbag (10) dépasse la valeur prédéterminée, les coutures déchirables (60) sont rompues et le raccord des extrémités gauche et droite de l'airbag (10) par rapport au sac interne (22) est libéré, ce qui permet aux extrémités gauche et droite de l'airbag (10) de se gonfler latéralement sur les côtés externes.
(JA)
 上下方向に迅速に膨張すると共に、左右方向にも十分に膨張するエアバッグと、このエアバッグを備えたエアバッグ装置。エアバッグ10内にインナーバッグ22が設けられている。エアバッグ10の左右両端側がテアシーム60によってインナーバッグ22に結合されている。エアバッグ10が膨張する場合、エアバッグ10の内圧が所定値に達するまでは、エアバッグ10の左右両端側の側方への膨張が規制されており、エアバッグ10の内圧が所定値以上になると、テアシーム60が破断してエアバッグ10の左右両端側とインナーバッグ22との結合が解除され、エアバッグ10の左右両端側が側外方へ膨張するようになる。
