Abstract
A retractor is provided with a tension relieving mechanism which is operated by a belt sensor for sensing a taut or slack condition of the belt. The belt sensor operates a blocking means between a blocking position in which the tension of the winding spring is relieved from the protracted belt on the passenger's shoulder and a release position in which the spring winding force is applied to the belt to rewind the belt. Preferably, a cam means is provided to hold the blocking means in its release position to rewind slack occasioned during slight forward protraction movements of the passenger when the belt has been initially set in the tension relieving state. In the preferred embodiment of the invention, the tension relieving mechanism is set into the tensionless condition immediately upon buckling of the belt tongue plate to a buckle. The amount of slack in the protracted belt cannot be increased by ratcheting past the teeth as with prior art tension relieving mechanisms.
