ABSTRACT:
A safety belt retractor for providing motor vehicle occupant protection is disclosed. The retractor has a rotatable spool for storing safety belt webbing and a rewind spring for exerting a retraction force on the belt webbing. The retractor includes a comfort mechanism for relieving the tension exerted on the belt webbing by the rewind spring. The comfort mechanism is actuated in response to a deliberate motion exerted on the belt webbing which is different than belt movements normally associated with operation of the retractor. The tension relief feature can be automatically cancelled in response to the occurrence of a predetermined condition for returning the belt webbing to a taut position.
