Abstract
A safety restraint system (10) for a vehicle comprising: a safety belt (20) having a seat belt portion connected to a buckle (64) and a shoulder belt portion connected to a motorized retractor which includes a reversible motor (34). The shoulder belt portion is received through a D-ring (60) having associated therewith a first angle sensor (80). The system additionally includes a logic control unit (104) which controls the system through various modes of operation. In its normal mode of operation the logic control unit monitors and stores the value of the D-ring (60) angle and initiates the rewind of the seat belt (20) during instances of excess shoulder belt slack. Upon rewinding the shoulder belt the motor (34) is commanded to reverse wind to pay-out a very small amount of the seat belt webbing thereby relieving shoulder belt tension.
