Abstract
【解決手段】歩行者等の衝突検知センサが衝突を検知するとインフレータ5に第1段目のガス噴出を行わせる。これにより、エアバッグ3が最終展開形状にまで展開する。その後、エアバッグ3内のガスがベントホール3aから流出することにより、エアバッグ3の内圧が所定圧まで低下してきた段階で歩行者等の衝突予知センサ若しくは衝突検知センサの少なくともいずれか一方が衝突を予知若しくは検知するとインフレータ5に第2段目のガス噴出を行わせる。これにより、エアバッグ内圧を長時間にわたって高く保ち、どの時点で歩行者等がエアバッグ3に突っ込んできても極めて十分に衝撃を吸収することができる。第1段目のガス噴出圧力、ガス量が従来例よりも低圧、少量で足り、エアバッグ3の要求強度等が緩和される。

Claims (3)
- 自動車の外面に沿って展開可能なエアバッグと、該エアバッグを膨張させるガス発生手段とを備えた外面展開型エアバッグ装置において、
該ガス発生手段は、経時的にガス発生時期を異ならせて複数回ガスを発生させるものであることを特徴とする外面展開型エアバッグ装置。 - 請求項1において、該エアバッグは、その内部からガスを流出させて衝撃を吸収するベント手段を有することを特徴とする外面展開型エアバッグ装置。
- 請求項2において、前記ガス発生手段は、第1段目のガス発生によりエアバッグを膨張させ、エアバッグ内圧が最大値を経て所定圧力にまで低下してきたときに第2段目のガス発生を行うものであることを特徴とする外面展開型エアバッグ装置。
