Abstract
【解決手段】助手席用エアバッグ装置M1は、エアバッグ40が、予備折りした後に、横折りと縦折りとを行う本折りを行って、ケース24内に収納されて車両に搭載される。エアバッグ40は、予備折り終了後の予備折り形状が、乗員側壁部41における上縁42の近傍部位60をガス流入口50と対向する位置に配置させるとともに、乗員側壁部41を周壁部48の下部側49に重ねて平らにする形状、としている。エアバッグ40の本折り時における横折り時、予備折り終了時のガス流入口50より後方側部位72が、後端72aを周壁部48の下部側49における下面側でガス流入口50に接近させるように、二つ折りした状態で、横折りされている。

Description
エアバッグが、
展開膨張完了時の形状として、乗員側で略鉛直方向に沿って配置される乗員側壁部と、乗員側壁部の外周縁から車両前方側に略円錐状に狭まる周壁部と、を備える形状とするとともに、展開膨張完了時の周壁部の下部側における前部側に、略水平方向に沿う開口面としてガス流入口を配置させ、ガス流入口周縁をケースに取り付ける構成として、
さらに、予備折りした後に、左右方向の折目を付けて前後方向の長さ寸法を小さくする横折りと、前後方向の折目を付けて左右方向の幅寸法を小さくする縦折りと、を行う本折りを行って、ケース内に収納されて車両に搭載される構成とし、
さらに、予備折り終了後の予備折り形状を、乗員側壁部における上縁の近傍部位をガス流入口と対向する位置に配置させるとともに、乗員側壁部を周壁部の下部側に重ねて平らにする形状、としている助手席用エアバッグ装置であって、
エアバッグの本折り時における横折り時、エアバッグの予備折り終了時におけるガス流入口より後方側部位が、後端を周壁部の下部側における下面側でガス流入口に接近させるように、折り返して形成した折り返し部を設けて、この折り返し部を重ねた二つ折りの状態で、横折りされていることを特徴とする。

Claims (3)
- ケース内に折り畳まれて収納されたエアバッグが、展開膨張時、ガス流入口から膨張用ガスを流入させて、インストルメントパネルの上面側に配置されたエアバッグカバーのドアを押し開いて、上方へ突出するとともに、車両の後方側へ展開膨張する構成として、さらに、
前記エアバッグが、
展開膨張完了時の形状として、乗員側で略鉛直方向に沿って配置される乗員側壁部と、該乗員側壁部の外周縁から車両前方側に略円錐状に狭まる周壁部と、を備える形状とするとともに、展開膨張完了時の前記周壁部の下部側における前部側に、略水平方向に沿う開口面として前記ガス流入口を配置させ、前記ガス流入口周縁を前記ケースに取り付ける構成として、
さらに、予備折りした後に、左右方向の折目を付けて前後方向の長さ寸法を小さくする横折りと、前後方向の折目を付けて左右方向の幅寸法を小さくする縦折りと、を行う本折りを行って、前記ケース内に収納されて車両に搭載される構成とし、
さらに、前記予備折り終了後の予備折り形状を、前記乗員側壁部における上縁の近傍部位を前記ガス流入口と対向する位置に配置させるとともに、前記乗員側壁部を前記周壁部の下部側に重ねて平らにする形状、としている助手席用エアバッグ装置であって、
前記エアバッグの本折り時における横折り時、前記エアバッグの予備折り終了時における前記ガス流入口より後方側部位が、後端を前記周壁部の下部側における下面側で前記ガス流入口に接近させるように、折り返して形成した折り返し部を設けて、該折り返し部を重ねた二つ折りの状態で、横折りされていることを特徴とする助手席用エアバッグ装置。 - 前記折り返し部が、先端を、前記ケースの後部側における前記ケースの内周面に沿う前記ガス流入口から前記エアバッグカバーにおけるドアのヒンジ部の高さ付近までの領域内に、配設させて、
前記エアバッグが、前記ケース内に収納されて車両に搭載されていることを特徴とする請求項1に記載の助手席用エアバッグ装置。 - 前記エアバッグの膨張時における前記折り返し部が折り返しの折りを解消するように展開する際の前記折り返し部が摺接する部位側、若しくは、摺接する前記折り返し部自体の部位側、の少なくとも一方に、摺接時の摺動抵抗を増大させる摺動抵抗増大手段が、配設されていることを特徴とする請求項1若しくは請求項2に記載の助手席用エアバッグ装置。
