ABSTRACT:
An apparatus for inflating a vehicle occupant restraint such as an airbag includes a housing. A canister including a lower section and a cover is located in the housing. Gas generating material is located within the canister. The gas generating material, when ignited, generates gas for inflating the air bag. An annular prefilter is disposed within the canister, radially outward of the gas generating material and radially inward of the side wall of the canister. The prefilter is resiliently deformed axially between the canister cover and the canister lower section to hold the prefilter in place in the canister.
