Provided is an airbag device in which, during a collision, a hood-type airbag is inflated and deployed in a state of being exactly sandwiched between a seated occupant shoulder and a seatbelt in a normally set state, thereby reducing injury to an occupant due to devices other than airbags such as seatbelts. This airbag device (11) is provided with: an airbag (12) that integrally covers the head (2a) and side sections of a seated occupant (2); and an inflator (13). The airbag (12), which is in a flat state before being folded, has a plurality of chambers (12c) divided in the longitudinal direction. The chamber (12c) has a head protection chamber (12ca) housed in the upper part of the backrest part (1b) of the seat (1), and a pair of side protection chambers (12cb) housed in opposite positions spaced apart in the vehicle width direction at both left and right side parts of the backrest part (1b). The airbag (12) is configured such that, when the airbag (12) is inflated and deployed, theside protection chamber (12cb) is inflated and deployed between the seat belt (3) and the occupant (2), thereby forming a space (S) between the airbag (12) and the occupant (2) that can be deployed ata position through which the seat belt (3) passes.

    本发明提供一种安全气囊装置,在碰撞时,机罩型安全气囊以被确切地夹在落座的乘员肩头和正常设定状态的安全带之间的状态进行膨胀展开,从而减轻因安全带等安全气囊以外的装置对乘员的伤害。本发明的安全气囊装置(11)具备:一体地覆盖落座的乘员(2)的头部(2a)和侧部的安全气囊(12),以及充气器(13)。且在折叠之前的平置状态的安全气囊(12)具有沿长度方向划分的多个腔室(12c)。腔室(12c)具有:收容在座椅(1)的靠背部(1b)的上部的头部保护腔室(12ca),以及,收容在靠背部(1b)的左右两侧部的车宽方向上隔开的相对位置上的一对侧部保护腔室(12cb)。安全气囊(12)构成为,膨胀展开时,侧部保护腔室(12cb)在安全带(3)和乘员(2)之间膨胀展开,从而能够在安全带(3)通过的位置展开的安全气囊(12)和乘员(2)之间形成空间(S)。
