1. A gas generator comprising:
- a housing having a first end and a second end;
a gas generating composition contained within said housing; and
an elastomeric pad comprisingan elastomeric polymer in an amount from about 30-70 weight percent relative to the total weight of the pad; and
an auto-igniting material having an auto-ignition temperature less than the ignition temperature of the gas generating composition.

Abstract
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.

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; and an 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. - View Dependent Claims (15, 16)
