초록

A vehicle occupant protection device comprises a body of gas generating material which comprises a solid solution of a water soluble liquid oxidizer and a hydrophilic polymeric gelling agent. The gelling agent comprises carbon atoms in an effective amount to function as a fuel with the liquid oxidizer. The solid solution also comprises water, preferably in the amount of about 5% to about 25% based on the weight of the body of gas generating material. The water reduces the temperature of the gas which is produced and also increases its volume, making the ...
