Abstract
A gas generator for an air bag system has, in a housing provided with a gas discharge port, igniters activated upon an impact, and gas generating agents ignited and burnt by the igniters and generate a combustion gas for inflating an air bag, and two combustion chambers storing the gas generating agents. The combustion chambers are concentrically provided so as to be adjacent to each other in the radial direction of the housing, and a communicating hole which allows communication between the combustion chambers is provided, in the housing. The gas generator also has two igniters, two different gas generating agents, a connector having a lead wire, a combustion chamber, igniters provided in an inner cylindrical member, and an automatic ignition member, which can effectively restrain an occupant.
