Abstract
An active tension remover for the seat belt of a safety restraint system having a housing attached to the seat belt retractor of the safety restraint system. A spring cap is rotatably supported in the housing and encloses a coil spring having one end attached to spring cap and the other end attached to spool of the retractor on which the seat belt is wound. A bi-directional motor disposed in the housing is operative to rotate the spring cap relative to the housing. A logic control responsive to the buckling the seat belt about the occupant of the seat actuates the motor to unwind the seat belt spool a predetermined number of turns to reduce the tension exerted by the seat belt in the shoulder of the occupant and to rewind the seat belt spool to its initial position in response to the unbuckling of the seat belt.
