A gas generator of a side impact air bag inflator comprises a propellant chamber having a proximate and distal end and a plurality of apertures radially disposed about said distal end. Upon combustion of propellant within the chamber, longitudinal flow of the resulting gases is created by virtue of the distal end apertures. Longitudinal gas flow through the chamber and then axially opposite through a filter quickens the deployment rate, and improves the filtering and cooling capability of a smaller side impact inflator.

[ We claim:] [1.] In an air bag inflator comprising an elongated cylindrical housing having a proximate end, a distal end and a first plurality of radially opening circumferentially-disposed apertures at the proximate end;a propellant chamber disposed centrally of said housing comprising proximate and distal ends corresponding to the proximate and distal ends of said housing;a second plurality of apertures radially disposed about the distal end of said propellant chamber for directing combustion gases radially from said chamber;a propellant in said chamber;means for igniting said propellant at the proximate end of said propellant chamber; andan elongated cylindrical filter coextensive with said housing and disposed radially outwardly of said propellant chamber and radially inwardly of an inner wall of said housing.
