Abstract
A hybrid inflator and method of inflating airbags include a pressure vessel which utilizes a solid propellant, a liquid fuel and a compressed oxidizing gas to produce an inflator gas for inflating devices such as airbags. The solid propellant vaporizes and superheats the liquid fuel, thus raising it above its autoignition temperature. When put in contact with the compressed oxidizing gas the liquid fuel ignites. The thus-ignited liquid fuel and compressed gas rupture a burst disk in the inflator to release the inflator gas for inflation purposes.
