Abstract:
[Problem] To provide an airbag device capable of securely restraining an occupant seated in a seat regardless of the posture of the occupant. [Solution] The present invention is an airbag device installed in a vehicle seat having a seat cushion that forms a seating surface, a seat back that forms a backrest, and a headrest disposed on the upper section of the seat back, said airbag device comprising an inflator that generates an expansion gas, and an airbag that is stowed at least in the seat back and is deployed by the expansion gas released from the inflator. The airbag includes a left-right pair of side chambers that deploy forward from side sections of the seat back, and an upper chamber that is provided so as to be connected to the side chambers and deploys above the head of the occupant. From a state in which the airbag is spread flat prior to being stowed, the airbag is rolled in a direction that intersects the longitudinal direction or is folded up to be compressed in a long rod shape. The part of the airbag corresponding to the upper chamber of the airbag in the long rod shape is stowed in a stowage section provided to the back side of the headrest above the seat back.
