    • An airbag (5) of an airbag apparatus is accommodated in a ceiling of a vehicle (2) in a folded state. The folded airbag (5) is formed by folding ends of an elongated folded intermediate, which extends along a direction of the width of the vehicle (2). Thus, the folded airbag (5) includes folded back portions (38) each including one of the ends of the folded intermediate. The folded airbag (5) is attached to the vehicle ceiling by means of attachment portions (27) each provided at one of the folded-back portions (38). Each folded-back portion (38) is not located outward of the upper end (32a) of the corresponding one of a pair of rear pillar garnishes (32) with respect to the width direction of the vehicle (2). When each folded-back portion (38) is pivoted about the corresponding attachment portion (27), a part of the folded-back portion (38) that is the furthest from the attachment portion (27) is pivoted at a predetermined pivoting radius (R), and the folded back portion (38) overlaps the headrest (10a) of the corresponding rear sheet (10) by an overlapping dimension (a), which is obtained by subtracting a minimum distance between the headrest (10) and the corresponding attachment portion from the pivoting radius (R). The width (W) of each folded-back portion (38) and the position of each headrest (10a) with respect to the width direction of the vehicle (2) are adjusted such that the overlapping dimension (a) is less than or equal to 40% of the pivoting radius (R).

    • An airbag device includes an inflator (30;50) for generating gas to inflate an airbag. The inflator (30,50) includes a bracket (31; 51). The roof (11,12,19) of a vehicle (10) includes a wall (19a) extending in lateral and longitudinal directions of the vehicle (10). The bracket (31;51) is fixed from below to the wall (19a). The bracket (31;51) includes an arm (33;53) extending rearwards from the inflator (30;50) and a hook (36;56) in the middle of a side edge of the arm (33;53). The hook (36;56) is arranged between a rear end of the arm (33;53) spaced from the inflator (30;50) and the front end of the arm (33;53) proximal to the inflator (30;50). The hook (36;56) extends towards the wall (19a). The hook (36;56) has a distal end bent towards the inflator (30;50). The wall (19a) of the roof (11,12,19) includes an engagement hole (24) for engaging the hook (36;56).
    • 气囊装置包括用于产生气体以使气囊膨胀的充气器(30; 50)。 充气机(30,50)包括支架(31; 51)。 车辆(10)的车顶(11,12,19)包括在车辆(10)的横向和纵向方向上延伸的壁(19a)。 支架(31; 51)从下方固定到壁(19a)。 支架(31; 51)包括从充气机(30; 50)向后延伸的臂(33; 53)和臂(33; 53)的侧边中部的钩(36; 56)。 钩(36; 56)布置在与充气器(30; 50)间隔开的臂(33; 53)的后端与靠近充气器(30; 50)的臂(33; 53)的前端 )。 钩(36; 56)朝向壁(19a)延伸。 钩(36; 56)具有朝向充气机(30; 50)弯曲的远端。 顶部(11,12,19)的壁(19a)包括用于接合钩(36; 56)的接合孔(24)。
