Even if the space between the vehicle seat and the roof or the trim of the vehicle cabin is narrow, the air bag can be prevented from interfering with the roof or the trim when the air bag is inflated and deployed, and expected protection performance can be achieved. An airbag device (21) is provided with an inflator (3) and an airbag (22) that integrally covers the head (12a) and side sections of an occupant (12) seated on a vehicle seat (9). The airbag (22) has a head protection chamber (2c b) that covers the head (12a) of the occupant (12) when expanded and deployed, and a side protection chamber (2c a) that covers the side part of the occupant (12), and is housed in a range from one side part to the other side part of a backrest part (9a) of the vehicle seat (9), for example, in a rolled state. An additional fold-back portion (22a) is provided on an outer peripheral portion of the backrest portion (9a) extending from the attachment end (22c) side of the airbag (22) so as to cover at least a part of the outer peripheral portion of the airbag (22) on the opposite side from the seated occupant (12).

    即便是车辆用座椅与车室的车顶或内饰物之间的间隔狭窄,也能够防止安全气囊膨胀展开时与车顶或内饰物相互干涉,发挥预期的保护性能。一种安全气囊装置(21),其具备充气器(3)以及将落座于车辆用座椅(9)上的乘员(12)的头部(12a)和侧方部一体地覆盖的安全气囊(22)。安全气囊(22)具有在膨胀展开时覆盖乘员(12)的头部(12a)的头部保护腔室(2c b),以及覆盖乘员(12)的侧方部的侧部保护腔室(2c a),并在从车辆用座椅(9)的靠背部(9a)的一侧部经由上部到另一侧部的范围上例如以卷曲成卷状的状态而被收纳。在从所述靠背部(9a)上的、所述安全气囊(22)的安装端(22c)侧延伸的外周部分设置附加折返部(22a),以覆盖所述安全气囊(22)的落座乘员(12)的相反侧的外周部分的至少一部分。
