Abstract
A method and apparatus for securing a heat sink/filter positioned between a pressure vessel and a diffuser in an air bag inflator. The pressure vessel is constructed so that upon activation of the inflator of the area of gas exiting the pressure vessel is smaller than the area of gas exiting the diffuser to create pressures in the pressure vessel that are higher than the pressures in the diffuser. This results in deformation of the pressure vessel that is equal to or greater than the deformation of the diffuser to maintain compression of the heat sink/filter between the pressure vessel and the diffuser during activation of the inflator.
