A side airbag device capable of preventing interference between a harness and an airbag is provided between a vehicle body and a seat. The side airbag device includes an airbag module an inflatable airbag and an inflator supplying a gas into the airbag, a base member including an airbag storage portion having a concave shape and storing the airbag module and is attached between a vehicle body door and the seat, and a retainer member holding the airbag storage portion from the rear side of the vehicle body. The base member includes a first through hole through which a harness of the inflator is inserted and a flange which is formed in the periphery of the first through hole. The retainer member includes a second through hole through which the harness of the inflator is inserted and which is provided at a position facing the first through hole.

Provided is an airbag device in which an inflator can be fixedly mounted easily. The airbag device includes an inflator which generates a gas; an airbag which is inflated by the gas generated by the inflator; a retainer which is provided with an insertion port into which the inflator is inserted; a bag ring which mounts the airbag in the retainer; and a spring which fixes the inflator inserted into the insertion port.

An actuator of an airbag device includes a main body portion, which is attached to an attachment base, and a cap including a fitting protruding portion that is inserted into a fitting recessed portion of the main body portion. The fitting protruding portion has a holding portion, which is inserted into a holding hole of a coupling member when fitted to the main body portion and holds a leading end portion of the coupling member, and a movement permitting unit that, when a ceiling portion of the cap is subjected to pressure of a combustion gas of a squib, causes the ceiling portion to move, and causes the holding portion to move from a holding position, wherein the holding portion is inserted into the holding hole of the coupling member, to a holding released position, wherein the holding portion is removed from the holding hole.

An inflator as well as a method of manufacturing an inflator, a module including an inflator and an airbag module. In an inflator, especially for a protective device in a vehicle, comprising plural components a sealant is applied in the area of abutting components, especially a sealant which adheres to both abutting components.

An occupant protection device for a vehicle includes a seat frame, an inflator and a side airbag. The seat frame is provided at a seat lower side of a side support portion. The seat frame includes an upright wall portion and an upper wall portion. The inflator is provided at the seat lower side of the upper wall portion. The side airbag is disposed between the side support portion and the seat frame. In an inflated state, the side airbag includes a first inflation portion that causes an upper portion of the side support portion to bulge to the seat upper side and the seat width direction inner side, and a second inflation portion that causes a lower portion of the side support portion to bulge to the seat upper side and the seat width direction inner side.
