Abstract
An inflator device for inflating an inflatable cushion of an inflatable cushion restraint system. The inflator device includes a reaction housing defining a reaction chamber containing a supply of gas generant material. An initiator device is connected to the reaction housing and is in reaction initiating communication with the supply of gas generant material. A filter housing is disposed around at least a portion of the reaction housing and at least in part defines a filter chamber. The filter housing includes an annular discharge opening. The produced inflation gas discharges from the filter housing to the inflatable cushion through the annular discharge opening. A filter is disposed in the filter chamber and external of the reaction housing.
