Abstract: This invention relates to an air bag inflation gas generator to feed gas for inflation of air bags such as air bags for absorbing collision shocks, life jackets, rubber, rafts, and escape chutes. The present invention comprises combustion chambers accommodating gas generating agents formed with separating members in the both ends of an elongate cylinder having gas outlets in the middle thereof, a cylindrical final filter installed inside the middle of the cylinder, intermediary filters installed between the final filter and the separating members in the cylinder, and orifices, facing toward the intermediary filters, opened at the separating members. The present invention may generate much larger volume of combustion gas generated from gas generating agents than the prior generators, purify a large volume of combustion gas completely, and control the burning of gas generating agents.

Abstract: This invention relates to an air bag inflation gas generator to feed gas for inflation of air bags such as air bags for absorbing collision shocks, life jackets, rafts, and escape chutes. The air bag inflation gas generator according to the present invention has a combustion chamber comprising a bottom-closed cylinder of a housing body and a lid covering the opening of the bottom-closed cylinder. The housing body comprises the bottom-closed cylinder, a flange extending outward and formed integrally with the opening of the bottom-closed cylinder, and an external cylinder formed on the periphery of the flange and bent toward the bottom of the housing body. A plenum chamber is formed by covering the external and bottom-closed cylinders with a covering member from the bottom of the housing body and by welding the covering member to the cylinders.
