Gas generator for air bag and air bag system

摘要

A gas generator is provided with a nonazide gas generating agent stored in a housing, and a plurality of openings for controlling combustion of the gas generating agent so that gas generated by the gas generating agent passes through the openings toward the air bag. The gas generator can be made smaller in size and lighter in weight by controlling the internal pressure of the gas generator, upon actuation, to be equal to or greater than 60 kg/cm2, but less than 100 kg/cm2, by adjusting the total area of the openings relative to the amount of the generated gas.
