Air bag assembly with diffuser

摘要

An air bag assembly includes an axially elongated inflator for generating gas. The inflator includes first and second ends and has a gas discharge opening located on the first inflator end. The air bag assembly also includes an air bag deployable upon generation of gas by the inflator. A diffuser cup engages the first inflator end on which the gas discharge opening is located. The diffuser cup diffuses the inflator gas into the air bag such that the inflator gas is spread more evenly into the air bag during air bag inflation. Preferably, the diffuser cup also retains the first inflator end to an end wall of a housing.
