Abstract: An airbag apparatus includes an airbag having an occupant-side surface and a vehicle-body-side surface opposite to the occupant-side surface when the airbag is inflated, and at least an upper chamber and a lower chamber separated from each other; a gas generator for deploying the airbag; and a gas distributor enclosing the gas generator and having outlet ports for allowing gas from the gas generator to flow into the upper chamber and the lower chamber. A check valve is provided for preventing the gas from flowing from the lower chamber to the upper chamber.

Abstract: A side airbag is disposed at a side of a seat of a vehicle and inflated with gas supplied from a gas generator. The side airbag includes a sub-bag disposed in a lower section of the side airbag to be inflated with the gas supplied from the gas generator, and an upper section of the side airbag is inflated with the gas from the sub-bag.

Abstract: For accommodating and fixing a substantially cylindrical inflator to an inflator holder, a method for fixing an inflator includes the steps of providing the first, second, and third press parts on an internal surface of the inflator holder at different locations in the peripheral direction of the inflator inserting the inflator into the inflator holder from one end of the inflator holder; and pressing the inflator at the first, second, and third press parts from an external periphery to fix the inflator. It is arranged that any of included angles between lines from a center of the inflator to the respective press parts is less than 180°.
