Abstract
An inflator for an airbag has a cylindrical housing forming a pressure vessel for storing inert gas within a first end portion; a second end portion forming a separate combustion chamber, and an intermediate diffusion portion interposed between the first and second end portions for exhausting gases from the inflator into an airbag. The inflator has a first gas generator subassembly disposed within the first end portion and in communication with the stored inert gas. A second gas generator subassembly has a combustion chamber which is disposed within the second end portion and isolated from the inert gas by one or more rupturable sealing disks. The actuation of the inflator can be accomplished such that one or both of the gas generators can be ignited. The ignition can be simultaneously or sequential permitting either very rapid full filling of the airbag or slower prolonged filling.
