Abstract

Abstract A reaction device for an air bag module includes a pair of spaced apart side walls adapted to support a cylindrical air bag inflator. A pair of spaced apart transverse walls extend between and connect the side walls. The side walls and the transverse walls cooperate to define (i) an air intake opening, (ii) a gas outlet opening, (iii) a venturi channel terminating in the gas outlet opening, and (iv) an air aspiration passage between the air intake opening and the venturi channel. The side walls are adapted to support the cylindrical inflator in a manner such that the cylindrical housing of the inflator spans the width of the reaction device. In addition, the gas dispensing nozzles of the inflator face the throat of the venturi channel. The reaction device, and the orientation of the inflator in the reaction device, facilitate the aspiration of significant quantities of ambient air during operation of the inflator.
