Abstract
【解決手段】 インフレータ5と、両端が車両の最後端の柱状フレームに設けられた固定点に定着され、袋帯状をなし、周方向に伸長させると長手方向が短縮するメッシュウェビング11内に収納された状態のエアバッグ12とを備える。エアバッグ12はルーフ3側の収納空間に沿って収容され、後突時に作動したインフレータ5から供給されたガスにより、収納空間での収容状態から固定点の取付金具13に、その両端が支持されつつ膨張して、メッシュウェビング11により、その膨張形状が規制された膨張体となる。この膨張体で、後突により後方に移動する車室内乗員の頭部を拘束する。
【選択図】 図2
Description
エアバッグ装置10のメッシュウェビング11の端部は、図3(a)に示したように、取付金具13の取付孔13aに縫い付け固定されている。メッシュウェビング11の端部にはメッシュウェビング11より強度の高い通常のウェビング端部補強材等が縫い付けられ縫い付け部11aが形成されている。一方、この縫い付け部11aを取り付ける取付金具13は略L字形をなした形鋼加工品で、一方のフランジに取付孔13aが形成され、他方のフランジにはボルト孔(図示せず)が形成され、取付金具13はこのフランジを介してCピラーのフレーム(図示せず)の所定位置にボルト止めされる。また、メッシュウェビング11の縫い付け具合は、図3(a),図3(b)に示したように、エアバッグ12の膨張時にメッシュウェビング11の向きが容易に変わる程度に、取付孔13aと縫い付け部11aとの間で調整されている。
図7は、折り畳まれたエアバッグ12をメッシュウェビング11内に収容した状態(図9(c)参照)を模式的に示した斜視図である。同図に示したように、メッシュウェビング11内に、所定幅の帯状に折り畳まれたエアバッグ12がメッシュウェビング11の長手方向に沿ってほぼ直線状に収容されている。この細帯状のメッシュウェビング11に収容されたエアバッグ12(図7参照)が、図6に示したように、所定のエアバッグ収納空間16内に収納される。
