Description
折り畳んだエアバッグとエアバッグに膨張用ガスを供給するガス発生器とを収納するケースが、下方を開口させた箱形状として、天井壁部と、天井壁部の外周縁の全周から下方に延びる筒状の側壁部と、を備えて構成されて、前輪の前方側における車体の前端部の下面側に配設されて、
ガス発生器が、エアバッグに供給する膨張用ガスを吐出する複数のガス吐出口を下端側に備えて、エアバッグとともに、天井壁部に固定され、
エアバッグが、膨張時にケースの開口から下方へ突出するとともに、膨張完了時に、エアバッグ装置の作動前より前輪の接地力を減少させつつ、前輪の制動と操舵とを可能に前輪の路面との接触状態を維持させ、かつ、歩行者の巻き込みを防止可能に下面側を路面に圧接させる内圧を確保して、路面と前輪の前方側における車体の前端部の下面との間を塞いで膨張するように、配設されていることを特徴とする。
