<p>A child's seat (10) 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 (S) is properly connected. A second warning signal is produced when the child's seat air bag (40) is not properly functioning or if the child's seat (10) is not properly held in place by the vehicle's seat belt system. Also disclosed is an air bag inflator including a pressure tank (184), a frangible membrane (196) for sealing gas under pressure within the tank, and a pyrotechnic squib (200) for rupturing the frangible membrane to deploy the air bag.</p> |
