Description
膨張完了時の形状を、頂部を前端側に配置させた略四角錐形状として、
後端側に略上下方向に沿うように配置されて、助手席に着座した乗員を受け止め可能に構成された乗員側壁部と、
上下および左右にそれぞれ壁部を備え、前記乗員側壁部から収束するように前方に延びる形状として、前端側を、前記収納部位に取り付けられる周壁部と、を備える構成とされ、
前記膨張用ガスを内部に流入可能なガス流入口が、前記下壁部の前端側において、前記乗員側壁部の左右方向中心よりも左右何れかの方向にずれて配置された助手席用エアバッグであって、
前記周壁部の前端側で、前記ガス流入口の中心を通り上壁部に向かって延びる中心線を基準に区画された左側周壁部および右側周壁部における、前記上壁部から前記ガス流入口の中心に到る、自由膨張可能な実質的周長が左右で同等とされていることを特徴とする。
前記乗員側壁部をガス流入口側に接近させるように平らに展開させ、予備折りエアバッグを形成する予備折り工程と、
前記予備折りエアバッグの左右方向の幅寸法を前記収容部位内に収納可能に縮めるように折り畳む左右縮小折り工程と、
前記予備折りエアバッグの前後方向の幅寸法を前記収容部位内に収納可能に縮めるように折り畳む前後縮小折り工程と、を具備して構成され、
前記左右縮小折り工程において、前記ガス流入口の中心を基準として、左右方向の周長が長い第1部位を折りが解消され易い折り方で折り畳み、左右方向の周長が短い第2部位を折りが解消され難い折り方で折り畳むことを特徴とする。
