ABSTRACT:
An inflator for inflating a vehicle occupant restraint, such as an air bag, includes a container (18) having a stored mixture of gases including a primary gas for inflating the air bag and a combustible gas. An actuator assembly (20) opens the container (18) and ignites the combustible gas as it flows toward the vehicle occupant restraint. Igniting the combustible gas creates a combustion reaction external to the container (18) which heats the primary gas as it flows toward the air bag. A combustion arrestor (22) minimizes the propagation of the combustion reaction into the container (18).
