摘要：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 firstdirection and a safing crash acceleration signal when a crash event is sensed in a seconddirection. A second crash accelerometer (34) provides a safing crash acceleration signalwhen a crash event is sensed in the first direction and a discriminating crash accelerationsignal 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 orsecond directions. The first actuatable restraint (18) is actuated when the first

accelerometer (22) provides the discriminating crash acceleration signal and either thesecond or third accelerometers provide a safing crash signal. The second actuatablerestraint (20) is actuated when the second accelerometer (34) provides a discriminatingcrash signal and either the first or the third accelerometer provides a safing crash signal.
