Airbag apparatus

摘要

The object is to provide an airbag apparatus capable of individually setting the pressure when the chambers divided in the airbag are inflated. When a gas generator (3) is operated, gas is emitted from gas jets (5) and flows into a first chamber (1a) and a second chamber (1b) through gas outlets (4a) and (4b) of a gas distributor (4), respectively; the chambers (1a) and (1b) are inflated; and an airbag (1) is deployed along the window side of a seet (10). The first gas outlet (4a) is larger in diameter than the second gas outlet (4b), so that the gas is supplied to the first chamber (1a) in larger quantities and at higher pressure than to the second chamber (1b). Consequently, the first chamber (1a) is inflated at high internal pressure.
