- 車両乗員脚部の前方に展開可能なニーバッグと、該ニーバッグを膨張させるガスを噴出口から噴出させるインフレータとを有するニーバッグモジュールであって、該インフレータは、ガス発生剤の反応ガスのみを噴出するパイロインフレータであるニーバッグモジュールにおいて、
該インフレータはインフレータホルダに内嵌して保持されており、
該インフレータは筒形であり、その長手方向の一端側の側周面に該噴出口が形成され、且つ該一端側の先端面からボルトが突設されており、
該インフレータホルダは、該インフレータの長手方向に延在するベース部及び該ベース部の両側辺から起立する2つの側面よりなる、該長手方向と交叉方向の断面形状がコ字形の本体部と、該長手方向の一端側を塞ぐ塞壁と、該本体部から起立して前記インフレータのガス噴出口に対峙するプレート部とを有しており、
該ベース部には、該インフレータホルダの内側に向って突出する凸段部が形成されており、該インフレータが該凸段部に当接することにより、該インフレータが該ベース部から離隔しており、
該塞壁にはボルト挿通孔が設けられており、前記ボルトが該ボルト挿通孔に挿通され、該ボルトにナットが締め付けられることにより、該インフレータと該インフレータホルダとが連結されていることを特徴とするニーバッグモジュール。 - 請求項1において、該本体部の両側辺部同士を跨ぐアーチ部を有することを特徴とするニーバッグモジュール。
- 請求項1又は2において、該ニーバッグの熱又は強度の高負荷部分に防災布又はパッチクロスが設けられていることを特徴とするニーバッグモジュール。
- 請求項3において、該ニーバッグの内部には、該ニーバッグにおける車両前方側の内面と車両後方側の内面の上下方向の途中部分同士をつなぐテザーが設けられており、
該ニーバッグの該テザーよりも下位に該インフレータが配置されており、
該ニーバッグの下半側の内面には、該テザーとの結合部が位置する高さまで前記防災布又はパッチクロスが延設されており、且つ該テザーの下面に前記防災布又はパッチクロスが設けられていることを特徴とするニーバッグモジュール。 - 請求項1ないし4のいずれか1項において、前記インフレータは互いに反対方向を指向した2個のガス噴出口を備えており、前記プレート部はインフレータを挟んで1対設けられていることを特徴とするニーバッグモジュール。
- 請求項1ないし5のいずれか1項において、前記インフレータは、容積1ft3の常圧の密閉タンク内においてガス噴出作動した場合に、作動後5mSec経過時のタンク内圧が35〜65kPaとなり、作動後15mSec経過時のタンク内圧が175〜245kPaとなり、タンク内の最高到達圧力が240〜300kPaとなる特性のものであることを特徴とするニーバッグモジュール。
