ABSTRACT:
A filter assembly is provided for fluid supplies for vehicle occupant restraint systems which employ a combustible gas generator to inflate a confinement upon the occurrence of a collision. The filter assembly includes two sets of layers of porous filter material.
One set includes a plurality of layers of fibrous filter material of relatively high porosity such as steel wool. The other set includes a plurality of layers of filter material arranged in order of descending porosity between the gas generator and the confinement and positioned intermediate the layers of the former set. Each of the layers of this other set is of substantially lower porosity than those adjacent layers of the former set.
