A load management system and method for controlling the activation sequence and
times of activation of motor vehicle occupant restraints when a high g event, such
as a crash, occurs. The system includes a microprocessor that processes inputs
from a number of devices including seat weight sensor, an occupant spatial position
detector, a buckle status detector, a belt sensor. The microprocessor is driven
by a load management procedure that includes a high g event routine that controls
the activation sequence of restraints so that the automatic locking restraint is
first activated, followed by the pre-tensioner and then by the air bag. The load
management procedure also includes an enable/disable procedure that controls the
enabling and disabling of the restraints according to a number of variables including
occupant weight, seat buckle status and belt extension status.
