Abstract

An apparatus (10) for helping to protect a vehicle occupant includes an inflatable vehicle occupant protection device (16) and a inflator (12) for providing inflation fluid to inflate the vehicle occupant protection device (16). A non-azide gas generating material is in the inflator (12). The non-azide gas generating material when combusted produces inflation fluid, which comprises carbon monoxide (CO) and nitrogen oxides (NOx). A catalyst system, which contacts the inflation fluid, is also in the inflator. The catalyst system is reactive with the carbon monoxide (CO) and nitrogen oxides (NOx) in the inflation fluid. The catalyst system comprises a zeolite and a catalytic material. The catalytic material is supported by the zeolite.
