Abstract
A gas generator 10 includes an autoignition composition that contains an alkali metal chlorate such as potassium chlorate as an oxidizer, a carboxylic acid such as DL-tartaric acid as a fuel, and a desiccant in operable communication therewith. Gas generating systems 180 such as vehicle occupant protection systems 180, containing the gas generator 10, are also provided.
Claims6
A nitrogen-free autoignition composition consisting of:
