A seat restraint tensioner (10, 110) for a seat restraint system (12) in a vehicle (14) includes a cable (84, 184) having a first end and a second end. The first end is operatively connected to a seat restraint of the seat restarint system (12). The seat restraint tensioner (10, 110) also includes a movable mechanism connected to the second end of the cable (84, 184) to apply a force for tightening the seat restarint when activated. The seat restraint tensioner (10, 110) further includes a rotatable cam (66, 166) cooperating with the cable (84, 184) to generate a clamping force toward the seat restraint to clamp the cable (84, 184) between the cam (66, 166) and a clamping surface (90, 190) to prevent reverse travel of the cable (84, 184) after tightening the seat restraint. |
