Abstract
Description
しかし、車両用シートのシートバックをリクライニングさせた場合や、向きが変更可能なシートに着座した乗員がシートを前向き以外の向きに変更した場合には、ステアリングホイールやコンソール、ドアや天井等から膨張展開した袋体では乗員の身体を十分に受け止められない場合がある。
図1〜図3に示すように、車両1は、車室内に、エアバッグ装置40を備えている。エアバッグ装置40は、車両用シート3と一体的に設けられている。
なお、シートバック32を傾動させるための具体的な構成については、所要の機能を実現できるのであれば、いかなるものとしてもよい。
ここで、前記「リクライニング軸35と同軸回りに揺動可能」とは、フレーム部材10がリクライニング軸35自体に支持される構成の他、リクライニング軸35と同軸配置であるが別体の回動軸にフレーム部材10が支持される構成を含む。また、前記「別体の回動軸」は、リクライニング軸35と平行だが別軸配置であってもよい。前記回動軸は、例えばシートバック32の側面に設けられている。
フレーム部材10は、軸中心の揺動(回動)に限らず、リンク機構等を介して傾動してもよい。フレーム部材10は、例えば車両用シート3が水平回転してシート前後方向の向きを変えた場合、これに倣いフレーム前後方向の向きを変えて、シート前後方向とフレーム前後方向とが一致した状態を維持する。
袋体42は、例えば折り畳まれた状態や巻回された状態でフレーム部材10の内部に収容され、インフレータ41からのガスの供給を受けてフレーム部材10から膨張展開する。袋体42は、1枚の基布、または互いに縫合された複数枚の基布により、袋状に形成されている。以下の袋体42に関する説明では、特に記載のない限り、袋体42の展開が完了した状態について説明する。
車両に衝撃が入力されると、エアバッグ装置40のインフレータ41が、高圧のガスを発生する。インフレータ41からガスが発生すると、ガスの供給を受けて最初に後部バッグ43が膨張展開する。後部バッグ43が膨張展開するとその幅方向両側から一対の前方延設部44にガスが供給され、一対の前方延設部44が膨張展開する。
以上により、エアバッグ装置40の作動が完了する。
図4は、本実施形態の変形例に係るエアバッグ装置を搭載した車両用シートを示す図であって、エアバッグ装置が展開した状態を示す側面図である。
図4に示すように、フレーム部材10は、シートバック32、及びシートバック32上に設けられたヘッドレスト34の後方を覆う後部カバー部15を一体に備えていてもよい。換言すると、フレーム部材10は、後部カバー部15の一部に設けられていてもよい。
例えば、上記実施形態では、エアバッグ装置40は、後部バッグ43と、一対の前方延設部44と、前部バッグ45とを備えるようにしたが、乗員100を有効に保護することができるのであれば、その形状、構成については、適宜変更することができる。
そして、上記実施形態における構成は本発明の一例であり、当該発明の要旨を逸脱しない範囲で種々の変更が可能である。
