Gas-generating agent for air bag
First Claim
1. A gas generating agent for an air bag comprising a fuel component, which is a nitrogenous organic compound, and an oxidizing agent as the major components of the gas generating agent, and at least 2.6% of silicon nitride functioning as consolidation preventing agent for at least either of said fuel component or said oxidizing agent, a metallic component being in said fuel component compound or in said oxidizing agent and said metal nitride further being able to react in a combustion process to form high-viscosity slag with said metallic component,further, containing an additional slag forming metallic component that can react with a metallic component of said metal nitride or oxide originating from the metal nitride in a combustion process to form said high-viscosity slag, the slag forming metallic component being an element or a compound.

Abstract
The present invention provides a gas generating agent for an air bag including a fuel component of nitrogenous organic compound and an oxidizing agent as its major components, to which at least one metal nitride or metal carbide that is allowed to react with a metallic component contained in the fuel component or the oxidizing agent to form slag is added, thus providing the effects of: solving the slag collecting problem which stands in the way of commercially practicing the nitrogenous organic compound base fuels; promoting the size reduction of the gas generator through the full use of high rate of gasification of the nitrogenous organic compound base fuels; and providing a gas generating agent molded member which is strong and stable with age by improving heat resistant properties and formability of the nitrogenous organic compound base fuels which are poor compared with the metallic compound azide of an inorganic matter.
