Gas Generator and Aspirator for Automatic Occupant Restraint Systems 720413
Development of reliable, low-cost inflators without toxic exhaust products is the key to successful inflatable occupant restraint systems. The characteristics and performance of gas generators and aspirator inflators are presented, together with cushion gas characteristics. Toxicity considerations, including both gaseous and aerosol constituents, are discussed. Results indicate that inflators can be produced that will meet stringent, yet realistic, toxicity requirements. The feasibility of the aspirator inflator has been established, and this unique device offers distinct and significant advantages over conventional direct inflation devices.
