Abstract
An elongated gas generator, designed especially for use on the passenger side of the front seat position of an automotive vehicle, has a combustion cartridge having a central, electrically initiated igniter surrounded by gas generant material. This, in turn, is surrounded by filtering screens and by a perforated, tubular housing. A pH neutralizing material is located adjacent the openings of the housing for neutralizing gases produced by the burning gas generant. At least one other perforated case encloses the housing, and multiple layers of wire cooling screens are interposed between the housing and the case enclosing it. The openings in the housing are arranged relative to those of the outer case so that a long path is created for gases passing through the cooling screens, parallel to the layers thereof. The cooled and filtered gases are discharged directly from the outer case into a structure to be inflated.
