Abstract
An airbag inflator having a reduced area filter and cartridge-loaded generant. The inflator has a tubular housing with a plurality of exit ports in a limited angular extent. A filter having the general shape of a section of a tube is received within the housing within the extent of the exit ports. The filter has lateral edges which are compressed to reduce the thickness of the filter along these edges, increasing the inner diameter of the filter. A hollow cylindrical cartridge may be provided to house a quantity of pyrotechnic gas generant. The cylindrical cartridge is received within the housing, with the filter interposed between the cartridge and the exit ports. The increased inner diameter of the filter permits the use of a larger diameter cartridge compared to a filter which has not had its lateral edges compressed, which in turn permits a shorter inflator to hold the same volume of generant. The housing may be formed by double impact extrusion to have two separate interiors, each having a generant cartridge. This will permit the cartridges to be fired separately, providing adaptive performance for the inflator.
