Abstract
An apparatus for deploying an inflatable vehicle occupant protection device (12) includes a pressure vessel (16) containing inflation fluid, and a source of thermal energy which heats the inflation fluid. An initiator assembly (17), when actuated, initiates an outlet flow of the inflation fluid from the pressure vessel (16). The initiator assembly (17) includes a first actuatable device (18) which varies the degree to which the thermal energy can heat the inflation fluid, and further includes a second actuatable device (20) which causes the source to release the thermal energy to heat the inflation fluid. The initiator assembly (17) is actuated in a selected one of a plurality of differing stages. The differing stages correspond to a plurality of differing deployment conditions, and include a "softest" stage in which only the first actuatable device (18) is actuated.
