Abstract
An apparatus for deploying an inflatable vehicle occupant protection device includes a container (302) defining a primary combustion chamber (333), a secondary combustion chamber (343), and a gas flow path (312) extending from the primary combustion chamber (333) to the exterior (345) of the container (302) through the secondary combustion chamber (343). The container (302) has first and second opposite end walls (308, 310), and further has inner and outer tubular wall structures (304, 306) extending longitudinally from one to the other of the end walls (308, 310). The secondary combustion chamber (343) has an annular shape defined between the tubular wall structures (304, 306). The primary combustion chamber (333) is one of a pair of primary combustion chambers (333, 335) having cylindrical shapes defined within the inner tubular wall structure (304). Each primary combustion chamber (333,335) contains a combustible mixture of gases under pressure and is separated from the secondary combustion chamber (343) by a corresponding rupturable closure part (316) of the container (302).
