Gas generator for an air bag and air bag system

Abstract

A gas generator for an air bag, in which conduction of heat generated by combustion of a gas generating agent is restricted to effectively reduce or inhibit a temperature increase of a diffuser side on an outer shell container, is provided and thus, reduces the maximum surface temperature of the diffuser. The gas generator includes a housing which has a diffuser shell with at least one gas discharge port and a closure shell for forming an accommodating space together with the diffuser shell and the gas generating agent, installed in the housing, ignited and burnt by an igniting unit to generate a combustion gas, wherein the gas generator further includes a heat transfer restricting member for making a conduction of heat generated by a combustion of the gas generating agent to the diffuser shell side smaller than that to the closure shell side.
