Abstract
A gas generator that can controllably allow the airbag to inflate and expand slowly at an initial stage of the inflation and thereafter inflate and expand rapidly so that the intended function of the airbag can be fulfilled. In the gas generator, an enclosed space (S) in a housing ( ) is partitioned into two combustion chambers ( ), in which gas generating agents ( ), a filtering member ( ) and an igniter ( ) are arranged, respectively. The combustion chambers ( ) are communicated to each other through the filtering member ( ). The igniters are operated with time difference so that the airbag can be inflated and expanded moderately by a small amount of gas generated in one combustion chamber at the initial stage of inflation and then is inflated and expanded rapidly by a large amount of gas generated in the respective combustion chambers, thus achieving multistage control of the expansion of the airbag.
