  • Air bag module with inflation detection device
    Patent number: 5639118
    Abstract: An air bag module includes an inflation detection device. The air bag module includes an air bag, an inflator for generating inflator gas to inflate the air bag, and a breakable device disposed on the air bag. The breakable device has a broken condition when the air bag is inflated to a properly inflated condition and the breakable device has an unbroken condition when the air bag is inflated to less than the properly inflated condition. Upon air bag deployment, the breakable device is broken when the air bag is inflated to the properly inflated condition and the breakable device remains unbroken when the air bag is inflated to less than the properly inflated condition. Thus, the breakable device verifies that the air bag has been properly inflated after air bag deployment.
