Description
第2の発明は、上記第1発明において、前記複数のテザーのそれぞれは、前記前後方向に延設されて前記エアバッグのフロントパネルとリアパネルとを連結しており、前記テザー保護部材は、前記第1テザーの前記車幅方向の長さとほぼ同等の幅を備えると共に、前記ガス発生器からの前記ガスを受け止めつつ前記車幅方向両端側へと導く、帯状の形状を備えていることを特徴とする。
テザー保護部材を、第1テザーの車幅方向の長さとほぼ同等の幅を有する帯状に構成する。このように、テザー保護部材を帯状とし、ガス発生器から噴出されるガスが第1テザーに衝突する位置に配置することにより、噴出ガスが第1テザーに直接衝突することを防止できるとともに、ガス発生器からのガスを受け止めつつ車幅方向両端側へと導くことができる。
第3の発明は、上記第1又は第2発明において、前記テザー保護部材は、前記エアバッグと同等の材質で構成した少なくとも1つの基布であることを特徴とする。
本願第3発明においては、テザー保護部材をエアバッグと同等の材質である基布で構成する。これにより、テザー保護部材をエアバッグに対して縫製により容易に固定することができる。また、テザー保護部材をエアバッグの内部に設けた状態で、そのエアバッグを折り畳み内装パネルの内部に収納することができる。

Claims (5)
- 車両の前後方向、車両の車幅方向、及び上下方向に膨張して車両乗員脚部の前方に展開するエアバッグと、
ガスを噴出して前記エアバッグを膨張させるガス発生器と、
前記エアバッグの内部に縫製により設けられ、前記ガス発生器に最も近い位置に設けられた第1テザー、及び、前記第1テザーの上方に設けられた第2テザー、を含む複数のテザーと、
を有し、
前記エアバッグの膨張展開時において、当該エアバッグの内部に、前記ガス発生器と前記第1テザーとの間の第1室、及び、前記第1テザーと前記第2テザーとの間の第2室、を含む複数の室が形成される乗員脚部拘束装置であって、
前記エアバッグの膨張展開時に前記ガス発生器から噴出されたガスにより膨張し、前記第2室側の複数箇所が前記第1テザーの前記第1室側の面に対し当接するとともに前記第2室側の前記複数箇所の間には非当接部分が生じるように、弛みをもつように設けられた、テザー保護部材を有する
ことを特徴とする乗員脚部拘束装置。 - 請求項1記載の乗員脚部拘束装置において、

前記テザー保護部材は、
前記第1テザーの前記車幅方向の長さとほぼ同等の幅を備えると共に、前記ガス発生器からの前記ガスを受け止めつつ前記車幅方向両端側へと導く、帯状の形状を備えている
ことを特徴とする乗員脚部拘束装置。 - 前記テザー保護部材は、前記エアバッグと同等の材質で構成した少なくとも1つの基布であることを特徴とする請求項1又は請求項2記載の乗員脚部拘束装置。
- 前記テザー保護部材は、前記ガス発生器から噴出されたガスの流路を有することを特徴とする請求項1乃至請求項3のいずれか1項記載の乗員脚部拘束装置。
- 前記ガス発生器は、火薬を用いてガスを噴出させることを特徴とする請求項1乃至4のいずれか1項に記載の乗員脚部拘束装置。
