Abstract
A gas generating material (140) for use in a vehicle occupant protection apparatus (10) comprises about 5% to about 20% by weight of the gas generating material, of a binder, 0 to about 50%, by weight of the gas generating material, of an energetic fuel, and an amount of oxidizer effective to oxygen balance the gas generating material. More than 50% by weight of the oxidizer is basic copper nitrate. The binder comprises at least about 20% by volume of the gas generating material.
