Description
シートベルトと、シートベルトにおいて装着時に乗員の腰部を拘束するラップベルトの領域に配置されるエアバッグと、エアバッグに膨張用ガスを供給可能なインフレーターと、を有する構成とされて、
エアバッグが、可撓性を有したシート体から構成される袋状として、折り畳まれてラップベルトに設けられた収納部位内に収納される構成とされるとともに、内部に膨張用ガスを流入させて、前上側に向かって突出するように膨張し、膨張完了時の外形形状を、乗員の脚部の上面と当接可能な脚当接面と、乗員の胸部から頭部にかけてを拘束可能な上半身拘束面と、を有するように、軸方向を左右方向に略沿わせた略三角柱形状とされていることを特徴とする。
エアバッグを、バッグ本体と、インフレーターと接続されてバッグ本体に膨張用ガスを流入させる導管部と、を備える構成とすることが、好ましい。
ガス貯留部とバッグ本体とを、左右方向側で複数個配設される連通孔により、連通させる構成とすることが、好ましい。
乗員側パネルを、脚当接面を構成する下側部位と、上半身拘束面を構成する上側部位と、を有するとともに、それぞれ、略六角形状とされる下側部位と上側部位とを一辺で連結させたような外形形状として、
前側パネルを、外形形状を、乗員側パネルの連結部位の左右に配置される縁部相互をそれぞれ結合させた残りの縁部相互を離隔させるように開いた状態の下側部位及び上側部位と、略一致させた略六角形状として、構成することが、好ましい。
上半身側膨張部を、上端側で乗員の頭部を受け止め可能に、構成し、
前側膨張部を、乗員の拘束時に、上半身側膨張部の上端側を脚側膨張部の前端側に接近させることを、抑制可能に、配設させる構成とすることが、好ましい。
