Description
ケースが、底壁部と、底壁部から延びる略四角筒形状の周壁部と、を有して、突出用開口を備える略箱形状とされ、
エアバッグカバーが、
突出用開口を覆うとともにエアバッグの展開膨張時に周縁を破断されつつエアバッグに押されて開き可能な扉部を、有した天井壁部と、
天井壁部において、扉部の開き時の回転中心となるヒンジ部側、若しくは、扉部の開き時の先端側から延びて、周壁部に取り付けられる取付片部と、
を備える構成の車両に搭載されるエアバッグ装置において、
取付片部が、周壁部に対して、取付片部と周壁部とに設けられた貫通孔を貫通させるように配置される複数のリベットにより、取り付けられる構成とされ、
ケースが、周壁部と底壁部との境界部位付近を、断面略円弧状に、湾曲させて構成され、
取付片部が、少なくとも1つのリベットの貫通部位よりも先端側となる端縁に、周壁部側に向かって突出する突出部を、備える構成とされ、
突出部が、取付片部の周壁部への取付状態において、周壁部と底壁部との境界部位を構成する湾曲部位と対向する位置に配置されるとともに、周壁部の外側面よりも前記底壁部の中央側に向かうように突出させ、かつ、突出端面における周壁部側の縁を位置規制縁部として、湾曲部位に対して非圧接状態で配置させるように、構成されていることを特徴とする。
当て板を、突出部の配置領域まで延びるように構成されるとともに、リベットを用いて、周壁部及び取付片部に連結させる構成とすることが、好ましい。
突出部を、ヒンジ部側に配置されるヒンジ部側取付片部の下端側のみに、形成させる構成とすることが、好ましい。
