PROBLEM TO BE SOLVED: To provide a head protection airbag capable of being smoothly stored on an upper edge side of a window, and also capable of securing occupant protection performance.SOLUTION: A head protection airbag 20 is formed of a hollow weave consisting of warps and wefts, and the approximately whole outer surface thereof is coated with a coating agent. The head protection airbag 20 comprises: a gas inflow part 22 which inflating gas flows into and expands to separate an indoor side wall part 23A and an outdoor side wall part 23B; and a non-inflow part 46 arranged adjacent to the gas inflow part 22. The indoor side wall part 23A and the outdoor side wall part 23B each comprise a peripheral edge border part 24 constituting a boundary with the non-inflow part 46, and a general wall part 25 surrounded by the peripheral edge border part 24. The general wall part 25 is constituted of a low intersection part LC which is set to be lower than the peripheral edge border part 24 in the ratio of the number of intersections. In the low intersection part LC, a woven structure is formed of n×m structures (n and m are both an integer of 1 or more; however, a 1×1 structure is excluded).SELECTED DRAWING: Figure 7

    【課題】窓の上縁側に円滑に収納させることができ、かつ、乗員保護性能も確保可能な頭部保護エアバッグを提供すること。【解決手段】経糸と緯糸とからなる袋織りによって形成されて、外表面を略全面にわたってコーティング剤により被覆される構成とされ、膨張用ガスを流入させて車内側壁部23Aと車外側壁部23Bとを離隔させるように膨張するガス流入部22と、ガス流入部22と隣接して配置される非流入部46と、を備える頭部保護エアバッグ20。車内側壁部23A及び車外側壁部23Bが、それぞれ、非流入部46との境界を構成する周縁境界部24と、周縁境界部24に囲まれた一般壁部25と、を備える。一般壁部25が、交錯度を周縁境界部24よりも低く設定される低交錯部LCから、構成される。低交錯部LCが、織り組織を、n×m組織(n,mはともに1以上の整数、ただし、1×1組織を除く)から、構成される。【選択図】図7
