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.
