Abstract
Molecular sieve zeolites are incorporated in the inflator device to assist in the inflation of airbags in passenger vehicles. The pre-loading of the molecular sieve zeolites with gases such as air or nitrogen or carbon dioxide provides for rapid airbag inflation and following inflation, additionally provides the remediation of at least a portion of the toxic waste gases generated by the exploding inflator device. Molecular sieve zeolites, particularly zeolites X, having been exchanged with lithium or calcium, provide high-capacity gas storage and enhanced toxic waste gas adsorption. The use of molecular sieve zeolites reduces risk of injury to occupants of vehicles from exposure to hot, toxic waste gases following airbag deployment.
