Abstract
An apparatus (10) comprises an inflatable vehicle occupant protection device (12) and an inflator (20) for inflating the inflatable vehicle occupant protection device. The inflator (20) has a wall (32) defining a chamber (40) in the inflator. Inflation fluid is stored at a predetermined pressure in the chamber (40). The apparatus (10) further comprises a first device (102) for generating electrical energy. The first device (102) is located in the chamber (40). A second device (106, 108) senses a change in the predetermined pressure and transmits a signal indicative of the change in the predetermined pressure through the wall (32). The second device (106, 108) is located inside the chamber (40) and is electrically connected to the first device (102). A third device (122, 124) senses the signal. The third device (122, 124) is located outside of the chamber (40).
