First Claim
1. A gas generating composition comprising:
- 6 to 16% by weight of (a) a fuel comprising polyacrylamide;
70 to 85% by weight of (b) an oxidizing agent comprising ammonium nitrate;
3 to 12% by weight of (c) a combustion accelerator comprising potassium perchlorate;
at most 5% by weight of (d) combustion rate regulators selected from the group consisting of carbon and metallic powders; and

Abstract
A gas generating composition for air bags to be used as occupant crash protection systems in automobiles, which is less toxic or dangerous, can be easily handled, has a high combustion efficiency and a high gas generation efficiency, produces few residue during combustion, can be safely manufactured and exhibits a high molding strength in the molding step; and a molded article thereof. The invention provides a gas generating composition containing (a) a fuel comprising at least one polymer compound selected from polyacrylic polymer compounds, polyacetal, urea resins, melamine resins, ketone resins and cellulose-based polymer compounds; (b) an oxidizing agent selected from ammonium nitrate and phase-stabilized ammonium nitrate; and (c) at least one combustion accelerator selected from oxyacid salts such as metal nitrates, metal nitrites, perchlorates and chlorates; a molded article thereof; and an inflator for air bags with the use of the same.
