Abstract
A seat belt retractor with a belt tension eliminator comprises a belt take up reel, a retracting spring, means for producing a belt fastening signal, and a tension eliminator which prevents retraction of the belt with a measure of slack in the same, so that the tension or stress exerted on the body of the belt wearer by the belt fastened is eliminated by rendering the force of the retraction spring to be inactive in the normal driving position and posture assumed by the belt wearer.
