Abstract
An occupant restraint device (10) for a vehicle includes an air bag (16) mounted in the vehicle door (14) and an accelerometer (30) for measuring sideways acceleration of the door (14). A controller (20) monitors the accelerometer output (34, 36) and determines if the door (14) is in a door opening event or if the vehicle is in a sideways crash condition. The controller (20) actuates the air bag (16) if a vehicle crash condition is detected and disables actuation of the air bag (16) if the vehicle door (14) is determined to be opening.
