A gas generator contains an anti-vibration, auto-igniting pad. The pad is formed from a mixture of a known auto-igniting composition mixed with an elastomeric polymer, and then cured, thereby forming a polymer-auto-igniting composition matrix. The pad is placed in thermodynamic communication with a housing on the gas generator, thereby enhancing the safety of the gas generator while yet providing a multi-functional pad. The pad is formulated to reduce vibrations when biased against an associated gas generant, while augmenting the amount of gas produced upon gas generator activation, while yet providing an auto-igniting material that is ignited during a high heat event.

1. A gas generator comprising: a housing having a first end and a second end;a gas generating composition contained within said housing; andan elastomeric pad comprising an elastomeric polymer in an amount from about 30-70 weight percent relative to the total weight of the pad; andan auto-igniting m
1. A gas generator comprising: a housing having a first end and a second end;a gas generating composition contained within said housing; andan elastomeric pad comprising an elastomeric polymer in an amount from about 30-70 weight percent relative to the total weight of the pad; andan auto-igniting material having an auto-ignition temperature less than the ignition temperature of the gas generating composition. 2. The gas generator of claim 1, wherein the elastomeric pad is auto-ignitable at a temperature from 150°-210° C. 3. A gas generating system comprising the gas generator of claim 1. 4. A vehicle occupant protection system comprising the gas generator of claim 1. 5. The gas generator of claim 1, wherein the elastomeric polymer comprises silicone. 6. The gas generator of claim 1, wherein the auto-igniting material comprises a fuel comprising a carboxylic acid, sugar, a tetrazole or salt thereof, or a mixture thereof. 7. The gas generator of claim 1, wherein the auto-igniting material comprises an oxidizer comprising an alkali metal nitrate, alkali metal perchlorate, alkaline earth metal nitrate, alkaline earth metal perchlorate, or a mixture thereof. 8. The gas generator of claim 1, wherein the elastomeric pad further comprises a molybdenum salt or a molybdenum oxide. 9. The gas generator of claim 1, wherein the auto-igniting material comprises a about 20-30% fuel, by weight percent, about 60-70% oxidizer, by weight percent, and about 10-20% molybdenum trioxide, by weight percent. 10. The gas generator of claim 1, wherein the elastomeric pad is biased against the gas generating composition. 11. The gas generator of claim 1, wherein the elastomeric pad is adjacent the first or second end of said housing. 12. The gas generator of claim 1, wherein the elastomeric polymer comprises urethane, silicone, rubber, cellulosic derivative, or a mixture thereof. 13. The gas generator of claim 1 wherein the elastomeric polymer comprises silicone, polyurethane, ethylene propylene diene monomer, or a mixture thereof. 14. A gas generator comprising: a housing adjacent an exterior of said gas generator;a gas generant contained within the housing;an initiator assembly and a booster composition, each contained within the housing; andan elastomeric and auto-ignitable pad contained within the housing,wherein the pad, when combusted, produces gases in an amount of up to 50% by weight of the pad, said weight percent determined by the total weight of the pad prior to combustion. 15. The gas generator of claim 14 wherein said pad comprises a fuel comprising a tetrazole, a triazole, a carboxylic acid, a sugar, or a mixture thereof; and an oxidizer comprising an alkali metal nitrate, an alkaline earth metal nitrate, a transition metal nitrate, a metal perchlorate, a non-metal perchlorate, or a mixture thereof. 16. The gas generator of claim 14 wherein the pad comprises a urethane, a silicone, a rubber, a cellulosic derivative, or a mixture thereof.
