Abstract

An apparatus and a method for producing inflation gas for use in inflating a vehicle occupant restraint are provided wherein a filter housed within a chamber of the apparatus effects gas redirection and particulate removal from at least a portion of the hot gas released from a gas generating material-containing first chamber of the apparatus, forming a hot gas having a significantly reduced particulate content. The apparatus includes a diffuser having one or more controlling orifices and exit ports to provide for the passage of inflation gas therethrough into the vehicle occupant restraint. There is at least an approximately 180°
cumulative change in gas direction between contacting the filter and the passage of the inflation gas into the diffuser.
