A gas generator composition for use with an airbag device or a seat belt pre- tensioner apparatus, the gas generating composition having improved stability over time and generating gas that contains substantially no carbon monoxide, the gas generation composition comprising ammonium nitrate as an oxidizing agent, powdery microcrystalline carbon as a reducing agent, and a stabilizer which inhibits the ammonium nitrate from decomposing. The contents of the ammonium nitrate, microcrystalline carbon, and stabilizer are 89 to 98.8 wt.%, 1 to 6 wt.%, and 0.2 to 6 wt.%, respectively, based on the total amount of these. The content of the microcrystalline carbon is desirably 1.5 to 6 wt.% based on that of the ammonium nitrate, while the content of the stabilizer is desirably 10 to 200 wt.% based on that of the microcrystalline carbon. The composition has excellent long-term stability especially at high temperatures, has a moderate combustion rate, generates substantially no carbon monoxide, has adequate sensitivity, and is easy to handle and inexpensive.

L'invention se rapporte à une composition génératrice de gaz comportant du nitrate d'ammonium en tant qu'agent oxydant, du carbone microcristallin pulvérulent en tant qu'agent réducteur, et un agent stabilisant qui inhibe la décomposition du nitrate d'ammonium. Cette composition comporte, par rapport à son poids total, 89 à 99 % en poids de nitrate d'ammonium, 1 à 6 % en poids de carbone microcristallin et 0,2 à 6 % en poids d'agent stabilisant. La quantité de carbone microcristallin représente de préférence 1,5 à 6 % du poids nitrate d'ammonium, et la quantité d'agent stabilisant représente de préférence 10 à 200 % du poids du carbone microcristallin. Cette composition possède une excellente stabilité à long terme, notamment à températures élevées, elle possède un taux de combustion modéré, elle ne génère sensiblement pas de monoxyde de carbone, elle présente une sensibilité correcte, elle est facile à manipuler et est peu coûteuse.
