Abstract
A modular inflator device for inflating an inflatable cushion of an inflatable cushion restraint system. The inflator device has an elongated cylindrical configuration and includes a supply of gas generant material to produce inflation gas upon reaction initiation. The inflator device includes a reaction housing defining a reaction chamber containing the supply of gas generant material. An initiator device is connected to the reaction housing and in reaction initiating communication with the supply of gas generant material. The reaction housing includes a plurality of radially oriented chamber discharge openings. Upon reaction initiation of the supply of gas generant material, the inflation gas discharges from the reaction chamber through the discharge openings. An initiator diffuser is disposed between the initiator device and the supply of gas generant material. The initiator diffuser includes a plurality of radially oriented diffuser discharge openings disposed in discharge orientation toward the reaction housing side wall. The reaction housing is connected to a filter housing, and a filter element is disposed within the filter housing and external of the reaction chamber.
