Abstract
A vehicle occupant protection system (10) for helping to protect a vehicle occupant (33) during a vehicle rollover condition includes a rollover sensor (68) for sensing a vehicle rollover condition. The rollover sensor (68) provides a signal indicative of the vehicle rollover condition. The system also includes a vehicle body portion (14) defining a vehicle occupant compartment (16). The vehicle body portion (14) also includes at least one actuatable power device (44; 52; 56) for, when actuated, helping to protect the vehicle occupant (33) in a rollover condition by modifying a characteristic of the vehicle body portion (14). A controller (28) actuates the power device (44; 54; 56) in response to the rollover sensor signal.
