Abstract
A seat belt system including a seat belt secured for movement over a D-ring wherein the D-ring includes a magnet and the seat belt includes a plurality of magnetized metal filaments. As the seat belt travels through the D-ring the magnet attracts the plurality of metal filaments and counteracts at least a portion of the normal force of the webbing on the D-ring provided by gravity. The shape or configuration of the magnet may also increase the arc length or radial travel distance about the D-ring to reduce bunching and correspondingly the force necessary to wind and unwind the seat belt.
