The invention provides an airbag device and an occupant protection device provided with the airbag device, wherein the airbag device can properly restrain an occupant even if the occupant moves to the inclined front side of a seat due to an eccentric collision or an inclined collision of a vehicle. An airbag device is provided with an airbag to which gas generated by an inflator is supplied during a collision of a vehicle and which is inflated and deployed forward by passing from the rear side to the upper side of a vehicle seat, and the airbag in the inflated and deployed state has a pair of front and rear chambers and an airbag body. A pair of front and rear chambers pass through the left and right sides of the head of an occupant and extend in the front and rear direction, and an airbag body communicates with the pair of front and rear chambers, is disposed on the front side of the occupant between the pair of front and rear chambers, and compressively deforms in a state of being supported by the pair of front and rear chambers when restrained by the occupant. The airbag device is configured so that at least the head of the occupant is prevented from entering the gap between the front and rear chambers and the airbag body when the occupant is constrained to the rear half.
本公开提供一种即使在车辆发生偏心碰撞或斜向碰撞而使乘员向座椅斜前方侧移动了时也能够适当地约束该乘员的安全气囊装置以及具备该安全气囊装置的乘员保护装置。安全气囊装置具备在车辆的碰撞时供给有由充气装置所产生的气体且从车辆用座椅的后方侧起在上方侧通过而向前方侧膨胀展开的安全气囊,膨胀展开状态下的安全气囊具有一对前后腔及安全气囊主体,一对前后腔从乘员的头部的左右两侧通过并在前后方向上延伸,安全气囊主体与一对前后腔连通并且在一对前后腔之间被配置在乘员的前方侧且在乘员的约束时以被一对前后腔支承的状态而压缩变形,安全气囊装置构成为在乘员的约束后半时至少抑制乘员的头部进入前后腔与安全气囊主体的间隙中的情况。
