PURPOSE: To prevent the generation of the secondary disaster such as burn and abrasion, by cooling the jetted gas by arranging the endothermic substance, in the jetting process of the generated gas into an air bag. CONSTITUTION: When the shock due to the collision, etc., of a vehicle is detected, a triggering device 3 is operated electrically, and a fuel gas generating agent in a gas generating agent chamber 2 explodes, and the high pressure gas is generated in a moment, and passes into a gas cooling chamber 4 through a passing port 5, and is jetted into an air gag from a gas outlet 6, and expands the air bag in a moment. At this time, in the gas cooling chamber 4, the high temperature gas makes contact with the endothermic substance, and heat exchange is carried out, and a lowered temperature state is generated in a moment, and when the gas passes through a screen 8, the combustion gas generated in the explosion of the gas generating agent is caught, and sound- suppressed, and jetted into the air bag. |
