Air bag-equipped child's vehicle seat and alarm/arming system therefor

摘要

A child's seat for use in motor vehicles, including an air bag and activation circuitry. Sensors on the seat emit a first signal confirming that the air bag is armed and that the seat belt is properly connected. A second warning signal is produced when the child's seat air bag is not properly functioning or if the child's seat is not properly held in place by the vehicle's seat belt system. Also disclosed is an air bag inflator including a pressure tank, a frangible membrane for sealing gas under pressure within the tank, and a pyrotechnic squib for rupturing the frangible membrane to deploy the air bag.
