To provide a head protection airbag device which enables a folded body of an airbag to be attached to the upper edge side of a window while properly restricting twisting of the folded body itself.SOLUTION: An airbag 20 which inflates and deploys so as to cover a window is formed at a folded body 40 which is folded so that the lower edge 20b side in a deployment state is moved close to the upper edge 20a side and a tape material 70 for prevention of collapse of the folded body 40 is wound around the folded body 40. Then, the folded body 40 is attached to the upper edge side of the window. A twisting restriction member 50 is assembled to the airbag and the airbag is attached to the upper edge side of the window as a bag attachment body 75. In the airbag, attachment piece parts which are attached to the body side of a vehicle are arranged parallel to each other at the upper edge side. The twisting restriction member 50 includes: a body part 51 having a length exceeding the attachment piece parts; and a rib 56 protruding from the body part. The bag attachment body 75 is formed with the tape material 70 wound therearound in a state that the twisting restriction member 50 is assembled to the airbag upper edge side in the folded body 40.SELECTED DRAWING: Figure 4
【課題】エアバッグの折畳体自体のねじれを的確に規制して、折畳体を窓の上縁側に取り付けることができる頭部保護エアバッグ装置を提供すること。【解決手段】窓を覆うように展開膨張するエアバッグ20が、展開状態の下縁20b側を上縁20a側に接近させるように折り畳んだ折畳体40に形成され、折り崩れ防止用のテープ材70を巻き付けられて、窓の上縁側に取り付けられる。エアバッグは、ねじれ規制部材50を組み付けられて、窓の上縁側に、バッグ取付体75として、取り付けられる。エアバッグは、上縁側に、車両のボディ側に取り付けられる複数の取付片部を並設させる。ねじれ規制部材は、複数の取付片部を超える長さの本体部51と、本体部から突出するリブ56と、を備える。バッグ取付体75は、折畳体におけるエアバッグ上縁側にねじれ規制部材50を組み付けた状態として、テープ材70を巻き付けられて構成される。【選択図】図4
