ABSTRACT:
A pyrotechnic inflator for an air bag includes a housing for containing gas generating material for inflating an air bag. The housing has a wall formed of rigid, porous material and serves both as a filter for entrapping contaminants from the gas that is generated within as the gas passes outward through the wall into the air bag and cools the gas by absorbing heat therefrom. Gas generating material and an ignition train is hermetically sealed in a bag or packet inside the porous housing which serves triple duty as a solid pyrotechnic container, a gas filter and a gas cooler.
