Abstract

A gas generator of a side impact air bag inflator comprises a propellant chamber (18) having a proximate and distal end and a plurality of apertures (24) 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 (24).
Longitudinal gas flow through the chamber and then axially opposite through a filter (32) quickens the deployment rate, and improves the filtering and cooling capability of a smaller side impact inflator.
