Abstract
Description
前記ロール折り部位における断面の中心側の空間部位を潰してなる圧縮部を設けて構成される頭部保護エアバッグの折り完了体であって、
前記ロール折り部位における断面の中心側を基準とした前記基布を積層させた上下左右の部位が、上側積層部、下側積層部、及び、左右の側面側積層部、を備えて構成されて、
前記圧縮部が、
前記上側積層部、前記下側積層部、及び、左右の前記側面側積層部を、前記ロール折り部位における断面の中心側に接近させるように圧縮させた断面形状とするとともに、
前記上側積層部と前記下側積層部との間に、左右の前記側面側積層部を配設される構成として、さらに、
左右の前記側面側積層部が、上下方向の中央付近を相互に当接させるように屈曲させた屈曲部を備えて、左右の前記屈曲部が、前記上側積層部と前記下側積層部とに圧接された状態としつつ、前記空間部位を埋めるように、配設されていることを特徴とする。
前記圧縮部における前記ロール折り部位の前記上側積層部の上面側に、前記上流側部位を蛇腹折りした蛇腹折り部位が、重なって配設されていることが望ましい。
H…空間部位、FP…フロントピラー部、SP…(圧縮部の)収納部位、W1,W2…窓、G…膨張用ガス、V…車両。
