Abstract
Abstract A housing for encasing a gas generator comprising a body formed of a metallic mesh having interconnected crossbars providing heat vent passages therebetween. Bearing support members of hightemperature plastic material are interposed between opposite ends of the generator and the housing. A mounting shield is spaced above the housing to deflect rising heat and direct it outwardly through the vent passages in the housing body.
