Abstract
An apparatus (10) for controlling actuation of a first actuatable restraint (18) and a second actuatable restraint (20) includes a first crash accelerometer (22) for providing a discriminating crash acceleration signal when a crash event is sensed in a first direction and a safing crash acceleration signal when a crash event is sensed in a second direction. A second crash accelerometer (34) provides a safing crash acceleration signal when a crash event is sensed in the first direction and a discriminating crash acceleration signal when a crash event is sensed in the second direction. A third crash accelerometer (90) provides another safing crash signal when a crash event is sensed in either the first or second directions. The first actuatable restraint (18) is actuated when the first accelerometer (22) provides the discriminating crash acceleration signal and either the second or third accelerometers provide a safing crash signal. The second actuatable restraint (20) is actuated when the second accelerometer (34) provides a discriminating crash signal and either the first or the third accelerometer provides a safing crash signal.
