Description
エアバッグが、
膨張完了時に窓の車内側を覆うように配置される膨張遮蔽部と、
膨張遮蔽部に連通されるとともに、エアバッグの膨張完了時に、膨張遮蔽部の車内側若しくは車外側に、膨張用ガスを流入させて膨らむ膨張遮蔽部の膨張部位と、膨張部位相互を重ねるように配置される重ね膨張部と、
を備える構成とされ、
重ね膨張部が、膨張遮蔽部の膨張完了後に膨張を完了させるように構成されるとともに、外形形状を略棒状として、膨張遮蔽部の上下の中間部位において、前後方向に略沿うように、配置されて、かつ、窓に隣接して配置されるピラー部と、車内側から見て重なるように、配置されているいることを特徴とする。
本発明の頭部保護エアバッグ装置では、エアバッグの膨張完了時に、膨張遮蔽部の車内側若しくは車外側に、重ね膨張部が、膨張遮蔽部の膨張部位と、膨張部位相互を重ねるように、配置されるとともに、この重ね膨張部は、外形形状を略棒状として、膨張遮蔽部の上下の中間部位において、前後方向に略沿うように配置される構成である。すなわち、本発明の頭部保護エアバッグ装置では、膨張遮蔽部が、重ね膨張部を配置させることにより、上下の中間部位を、実質的に厚く膨張させるように膨張する構成である。そして、この重ね膨張部は、棒状に膨張する構成として、前後方向に略沿って配置されることから、剛性を有するような態様となり、乗員の頭部を受け止めても屈曲し難く、また、窓に隣接して配置されるピラー部の車内側に重なるように配置されることから、乗員の頭部の受け止め時に、車外側を、膨張遮蔽部を介在させて間接的に、あるいは、膨張遮蔽部を介在させずに直接的に、ピラー部に支持させることができる。さらに、重ね膨張部は、膨張遮蔽部の膨張完了後に膨張を完了させるように構成されていることから、乗員の受け止めタイミングの比較的遅いロールオーバー時に、車外側に向かって移動してくる乗員の頭部を、ピラー部に車外側を支持させつつ前後方向に沿った棒状として配置される重ね膨張部によって、前後に広いエリアにわたって、的確に拘束することができる。そのため、本発明の頭部保護エアバッグ装置では、膨張完了時の下縁側をベルトラインより下方に位置させなくとも、ロールオーバー時に、乗員の頭部を的確に拘束することができる。
重ね膨張部を、連通部を介して膨張遮蔽部と連通させる構成とし、連通部の部位で折り返すことにより、膨張遮蔽部の車内側若しくは車外側に配置させる構成とすることが好ましい。
重ね膨張部を、副膨張部に連通させ、
重ね膨張部を副膨張部に連通させる下流側連通部を、副膨張部を主膨張部に連通させる上流側連通部よりも、開口面積を小さく設定することが、好ましい。
