Abstract
A vehicle occupant protection apparatus (10) comprises an inflatable vehicle occupant protection device (12) having a deflated condition and an inflated condition for helping to protect a vehicle occupant. An inflator (14) is actuatable to provide inflation fluid to inflate the protection device (12). A retainer (40) is connected with the protection device (12). One of the inflator (14) and the retainer (40) is movable between a first condition blocking venting of inflation fluid from the apparatus (10) and a second condition venting inflation fluid from the apparatus. The apparatus (10) includes an electrically energizable mechanism (80) to release the one of the inflator (14) and the retainer (40) for movement from the first condition to the second condition to vent inflation fluid from the apparatus. The apparatus (10) also includes vehicle electric circuitry (90) including a sensor (92) for sensing at least one occupant condition or vehicle condition and a controller (100) responsive to the sensor for controlling the electrically energizable mechanism (80).
