Patent ID: 7040657

Claim:
A method of reducing nitrogen oxide generated upon actuation of a hybrid inflator for an inflatable safety system of a vehicle provided with an airbag including an inflator housing charged with a pressurized medium, a gas generator which is accommodated in the inflator housing and has at least one gas generating chamber, and an igniting means connected to the gas generator for generating a combustion product, comprising: providing in the gas generating chamber a tubular member including a plurality of flame transferring holes disposed axially and circumferentially about said tubular member, said tubular member defining therein a charge transferring chamber; providing in the gas generating chamber a body of gas generating agent including a fuel and an oxidizing agent; providing within the gas generating chamber a body of reducing compound capable of reducing nitrogen oxide that is separate from the body of gas generating agent such that the body of reducing compound and the body of gas generating agent are located together adjacent said tubular member and directly facing the plurality of flame transferring holes, and introducing the combustion product into the gas generating chamber.
