ABSTRACT:
A tubular inflator has a bulkhead that divides the inflator into a first and second combustion chambers. Each combustion chamber has an igniter assembly, gas generant, and compressed wire filter. The wire filters in the inflator are positioned so that they contact the bulkhead. The filters and the bulkhead prevent sympathetic ignition in the inflator, which is defined as the ignition of gas generant in one combustion chamber from the heat generated from the burning of the gas generant in the other combustion chamber. The igniter assembly has an igniter core that is molded by a unitary plastic material. The plastic overmold has threads for attaching the igniter assembly to the inflator, and the plastic overmold has a retainer portion for retaining an enhancer tablet.
