Title
(EN) AIRBAG DEVICE
(FR) DISPOSITIF DE COUSSIN DE SÉCURITÉ GONFLABLE
(JA) エアバッグ装置
Abstract
(EN) [Problem] To provide an airbag device that can protect an occupant appropriately in a vehicle adopting what may be called an irregular steering wheel, even if a high pressure is imparted from the occupant to an inflated and deployed airbag cushion. [Solution] The present invention is an airbag device for installation on an automobile steering wheel having a rim with a shape such that the distance from the center of rotation thereof to the upper edge thereof is less than the distances to the left and right edges thereof, the airbag device comprising: a gas generator which is secured to the steering wheel and which generates an inflation gas; and an airbag cushion that is inflated and deployed toward an occupant side by the inflation gas. The airbag cushion comprises a vent hole through which the inflation gas is exhausted. The vent hole is provided at a position such that when the occupant abuts against the inflated and deployed airbag cushion, the airbag cushion deforms toward the front of the vehicle, and a portion of the upper region of the airbag cushion advances forward past the rim of the steering wheel, said portion abuts against the automobile interior trim and causes the vent hole to be closed off.
(FR) Le problème décrit par la présente invention est de fournir un dispositif de coussin de sécurité gonflable qui peut protéger un occupant de manière appropriée dans un véhicule adoptant ce qui peut être appelé un volant de direction irrégulier, même si une pression élevée est communiquée de l'occupant à un coussin de coussin de sécurité gonflable gonflé et déployé. La solution de la présente invention porte sur un dispositif de coussin de sécurité gonflable destiné à être installé dans un volant de direction d'automobile ayant un bord revêtant une forme telle que la distance entre le centre de rotation correspondant et le bord supérieur correspondant est inférieure aux distances par rapport aux bords gauche et droit correspondants, le dispositif comprenant : un générateur de gaz qui est fixé au volant de direction et qui génère un gaz de gonflage ; et un coussin de coussin de sécurité gonflable qui est gonflé et déployé vers un côté occupant par le gaz de gonflage. Le coussin de coussin de sécurité gonflable comprend un trou d'évent à travers lequel est évacué le gaz de gonflage. Le trou d'évent est disposé à une position telle que lorsque l'occupant vient en butée contre le coussin de coussin de sécurité gonflable gonflé et déployé, le coussin de coussin de sécurité gonflable se déforme vers l'avant du véhicule, et une partie de la région supérieure du coussin de coussin de sécurité gonflable avance vers l'avant au-delà du bord du volant de direction, ladite partie venant en butée contre la garniture intérieure de l'automobile et amenant le trou d'évent à être fermé.
(JA) 【課題】所謂異形のステアリングホイールを採用した車両において、膨張展開したエアバッグクッションに対して乗員から大きな圧力が加わったときにも、当該乗員を適切に保護することができるエアバッグ装置を提供することを目的とする。 【解決手段】本発明に係るエアバッグ装置は、回転中心から左右縁部までの距離に対して上縁部までの距離が短い形状のリムを有する車両のステアリングホイールに搭載されるエアバッグ装置であって、前記ステアリングホイールに固定され、膨張ガスを発生するガス発生器と;前記膨張ガスによって乗員側に向かって膨張展開するエアバッグクッションと、を備える。前記エアバッグクッションは、前記膨張ガスを排気するベントホールを備える。そして、膨張展開した前記エアバッグクッションに乗員が当接し、当該エアバッグクッションが車両前方に向かって変形し、前記エアバッグクッションの上方領域の一部が前記ステアリングホイールの前記リムよりも前方に進出した時に、自動車内装部品に当接して塞がれる位置に前記ベントホールが設けられる。
