Provided is a head protection airbag device capable of stably deploying and inflating an airbag on the inside of a vehicle when the airbag is deployed and inflated. The head protection airbag device is configured so as to have an airbag that is folded and housed in the front-rear direction on the upper edge side of a window on the inside of a vehicle, and that expands and expands downward so as to cover the inside of the window when inflation gas from an inflator flows into the airbag. The airbag (20) is provided with a window shielding expansion part (27) which covers the vehicle inner side of the window. The folded shape (61) of the window shield expansion section (27) is configured so as to have: an inner folded section (62) which is folded toward the vehicle inner side (I) so that the lower edge (20b) side of the airbag approaches the upper edge (20a) side; and an outer folded section (64) which is disposed on the center (64a) side of the inner folded section, and which is folded toward the outside (O) of the vehicle so as to approach the upper edge side of the airbag.

    提供一种能够使展开膨胀时的气囊稳定地在车内侧展开膨胀的头部保护气囊装置。头部保护气囊装置构成为具有气囊,该气囊以沿着前后方向的方式折叠收纳于车辆的车内侧的车窗的上缘侧,在来自充气机的膨胀用气体流入时,以将车窗的车内侧覆盖的方式向下方展开膨胀。气囊(20)具有将车窗的车内侧覆盖的车窗遮蔽膨胀部(27)。车窗遮蔽膨胀部(27)的折叠形状(61)构成为具有:内卷折部(62),其以使得气囊的下缘(20b)侧接近上缘(20a)侧的方式朝向车内侧(I)卷折;以及外卷折部(64),其将内卷折部配置于中心(64a)侧,并且以接近气囊的上缘侧的方式朝向车外侧(O)卷折。
