1. Apparatus for inflating a vehicle occupant restraint comprising:
- a housing;
a canister in said housing having first and second spaced apart opposed axially inwardly facing surfaces;
gas generating material within said canister which when ignited generates gas for inflating the vehicle occupant restraint; and
a filter in said canister for filtering the gas generated by the gas generating material,said filter being compressed by said first and second opposed axially inwardly facing surfaces of said canister by an amount sufficient to hold said filter in place in said canister, said opposed axially inwardly facing surfaces being spaced form each other by a distance which is less than the uncompressed height of said filter.

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.
