Abstract
A pressure vessel for an air bag inflator. The pressure vessel has a portion that is deformable by internal pressure resulting from combustion of gas generant therein. The deformable portion of the pressure vessel has at least one exit orifice therein. Upon deformation of the pressure vessel portion by internal pressure, the size of the exit orifice is increased to expedite the release of pressurized combustion gas from the pressure vessel.
