Abstract
An energy absorbing seat belt retractor used with a seat belt assembly of a motor vehicle. The seat belt retractor includes a reel for winding and unwinding the seat belt and an elongated shaft, with the reel attached to the shaft. In one example, a movable disc is connected to and moves longitudinally along the shaft. At least one of the reel or movable disc includes a friction layer providing a friction surface such that when the movable disc is driven axially toward the reel there is frictional engagement between the reel and movable disc that absorbs impact energy on the occupant and limits the load applied to the seat belt.
