PATENT 1996-21-00 ABSTRACT OF THE DISCLOSURE Because of the length of the airbag gas generator that is used on the passenger side of an automotive vehicle, it has been extremely difficult and expensive to provide an ignition system that would ignite solid gas generant pellets and wafers uniformly throughout the entire length thereof. In order to effect ignition of all, pellets throughout the length of the gas generator combustion chamber substantially simultaneously, there is positioned in concentric relation therein an elongated BKNO3 solution dipped igniter tube having similarly dipped disks positioned thereon in spaced relation, transversely thereof. BKNO3 powder initiated by a squib directs fire down the igniter tube to produce a rapid flash of fire that ignites the BKNO3 dipped igniter tube and disks and surrounding gas generant pellets. The hot gas from the gas generant pellets is cooled and filtered by a screen pack assembly prior to exiting through holes in the cylindrical wall of the gas generator and directed to an airbag for inflation.
