Abstract
A generant cartridge for incorporation into an airbag inflation module, is produced by shrink wrapping a plastic envelope around gas generant pellets or wafers thereby completely encapsulating the gas generant in a hermetically sealed envelope. The gas generant cartridge may be prepared at one location and brought to an assembly line located at another location. As a result, the assembly of the generant into the module inflator is simplified. The gas generant may be shrink wrapped with an entire filter assembly or with only a portion of the filter assembly and then inserted into an inflator. A booster charge for rapid ignition of the gas generant may also be inserted in the cartridge.
