Abstract

A linear bilateral inflator module in which the inflator component of the module has two opposed cylindrical combustion chambers mounted in a horizontal plane at either end of the inflator. These chambers are joined to and supported by a central T-shaped inflator housing containing an ignitor for initiating combustion of the propellant within the inflator. The lower leg of this central section is configured as a tubular extension which may optionally be joined to a separate conduit member adapted for permitting a reciprocal fluid flow into and out of the air bag through the inflator. The extension also serves as a point of attachment for an outer surrounding base plate assembly. A bead, located within the mouth portion of the air bag, is trapped between the inflator and the base plate during formation of the structural seal between these components such that the inflator is completely enclosed within the bag. The inflator is adapted to provide differing amounts of a gaseous combustion product from each of the combustion chambers by varying the amount or type of propellant stored therein. This arrangement permits the development within the air bag component of the module of two different inflation zones.
