Abstract
Description
また、エアバッグ本体の内部にガスが供給されることでエアバッグ本体が膨張して、エアバッグ本体がインストルメントパネル側から車両用シートに着座した乗員の前方側へ展開する。
さらに、サブエアバッグの内部にガスが供給されることでサブエアバッグが膨張して、サブエアバッグがエアバッグ本体における車幅方向内側の部分とインストルメントパネルとの間へ展開する。
ここで、カーテンエアバッグとエアバッグ本体とが当接すると、エアバッグ本体が車幅方向内側へ向けて変位することが考えられる。しかしながら、請求項1記載のエアバッグ装置では、エアバッグ本体の車幅方向内側への変位をサブエアバッグによって規制することができる。これにより、カーテンエアバッグと当接したエアバッグ本体の車幅方向内側への変位を抑制することができる。
次に、本実施形態の作用並びに効果について説明する。

18B 突出部
