Abstract
A hybrid inflator for inflating vehicle air bags includes a first pressure vessel containing a compressed gaseous fuel, and igniter assembly and a second pressure vessel containing a compressed inflator gas. In use, the compressed fuel gas is released into the compressed inflator gas vessel using an igniter assembly for ignition of the gaseous fuel. Ignition of the gaseous fuel in the second pressure vessel causes a pressure and temperature rise which ruptures a burst disk in the second pressure vessel for gas release and inflation of an air bag.
