Abstract

An inflator includes a housing and a gas source material enclosed in a rupturable container in the housing. The gas source material is adapted to undergo decomposition to form an inflation gas. A reactant material is adapted to react with the gas source material to produce decomposition thereof, and is positioned in a cavity extending between a housing outer wall and an enclosure positioned within the housing. The container and an expandable bladder are positioned in the enclosure. Ignition of a propellant within the bladder generates combustion gases, thereby expanding the bladder. Bladder expansion forces portions of the container into openings formed along the enclosure, thereby stressing and rupturing the portions of the container in the openings and releasing gas source material to flow through the openings into the cavity, where it reacts with the catalyst to produce inflation gas.
