Abstract
Abstract A gas generator for inflating a bag comprising a deflagration composition yielding a gas comprising principally carbon dioxide and water vapor comprises a substantially homogeneous mixture of citric acid powder in the range of from about 23 to 37 percent by weight and an oxidizer powder selected from the group consisting of potassium chlorate, potassium perchlorate sodium chlorate, and sodium perchlorate. This composition is used adjacent a coolant powder comprising up to about 40 percent by weight of potassium chlorate and an endothermic decomposition coolant having a thermal decomposition product selected from the class consisting of carbon dioxide and water.
