Abstract
A spontaneous ignition agent for an air bag gas generator with excellent temperature resistance comprises essentially nitrocellulose, an inorganic oxidizing agent, and carbon.
Claims12
Air bag gas generator, comprising:
- a propellant;
- an ignitor with ignitor charge;
- and
- a spontaneous ignition agent which ignites at a temperature that is markedly higher than a normal ambient temperature but substantially lower than an ignition temperature of said propellant, said spontaneous ignition agent comprising;
- a mixture of nitrocellulose, an inorganic oxidizing agent, carbon as fuel for the inorganic oxidizing agent, wherein a percentage of nitrocellulose ranges from 20 to 70 wt. %, and a percentage of carbon is at least 3 wt. %.
Air bag gas generator comprising a propellant, and an igniter with ignitor charge, and a heat stable spontaneous ignition agent which ignites at a temperature that is markedly higher than normal ambient temperature but substantially lower than the ignition temperature of the propellant, the spontaneous ignition agent comprising an intimate mixture of nitrocellulose, an inorganic oxidizing agent and carbon as fuel for the inorganic oxidizing agent, wherein the nitrocellulose is present in an amount by weight of about 20 to 70% and the carbon is present in an amount by weight of at least about 3%, and the spontaneous ignition agent is heat stable to about 105.degree. C. and the inorganic oxidizing agent is an alkali or alkaline earth nitrate, chlorate, perchlorate or peroxide.
