ABSTRACT:
An inflator for generating gas to inflate an air bag in a vehicle occupant safety apparatus comprises gas generating material, a plurality of filter layers, and a strand extending around the filter layers. The gas generating material generates gas when ignited. The filter layers filter the gas as it flows through the filter layers, and encircle the gas generating material. The filter layers include an outer layer with a cylindrical outer surface. The strand extends around the cylindrical outer surface of the outer filter layer at least partially in a helix, and has a plurality of circumferentially extending turns. The turns in the strand are spaced apart axially to define a helical gap which permits the gas to move from the cylindrical outer surface past the strand toward the air bag.
