GAS GENERATOR

摘要

A gas generator capable of performing the intended function of an air bag by controlling the air bag so that the air bag can be expandedly inflated slowly at the initial stage of the expansion and then expandedly inflated rapidly, wherein an enclosed space (S) in a housing (1) is divided into two combustion chambers (3, 4), gas generating agents (6), filter members (7), and ignitors (8, 9) are arranged in the combustion chambers (3, 4), respectively, and the combustion chambers (3, 4) are formed in communication with each other through the filter member (7), whereby, by operating the ignitors at a different timing between them, the air bag can be controlled in multiple stages in which the air bag is expandedly inflated slowly by a small amount of gas produced in one combustion chamber at the initial stage of the expansion of the air bag and then expandedly inflated rapidly by a large amount of gas produced in both combustion chambers.
