To provide a head protective airbag device capable of smoothly expanding and inflating an airbag even when an inflation portion extending to the lower side of a belt line is arranged at a front end side of the airbag.SOLUTION: An airbag 20 is configured by arranging at a front end side, an inflation portion 37 covering an indoor side of a vehicle inner wall 9 exceeding a belt line BL at a lower edge side of a front window W1. In the airbag, a storage form 50 at the time of storage is a shape in which a roll folding part 53 rolled to a vehicle outside is provided so as to make a lower edge side in a state of being flatly expanded approach an upper edge side, and a front end folding part 50b stored in a front pillar part FP including an inflation portion in the roll folding part is twisted in a vehicle inside direction for an angle of less than 90° rather than the other folding part 50a, on the basis of a bottom edge 53a side of the roll folding part 53.SELECTED DRAWING: Figure 8

    【課題】エアバッグの前端側にベルトラインの下方に延びる膨張部位を配設させていても、エアバッグを円滑に展開膨張させることの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】エアバッグ20が、前端側に、前窓W1の下縁側のベルトラインBLを越えた車内壁9の車内側を覆う膨張部位37、を配設させて構成される。エアバッグは、収納時の収納形態50を、平らに展開した状態の下縁側を上縁側に接近させるように、車外側に向けて巻くロール折畳部53を設けるとともに、ロール折畳部における膨張部位を含んでフロントピラー部FPに収納される前端折畳部50bを、他の一般折畳部50aより、ロール折畳部53の下端53a側を基準として、車内側方向に90°未満の角度分、捩じられている形状、としている。【選択図】図8
