ABSTRACT:
A small-sized, light-weight, low-priced tensionless seat belt retractor such that it is possible to provide a necessary, sufficient, safe slack to the driver or the passenger under a tensionless condition. The tensionless seat belt retractor according to the present invention comprises a follower and a guide disk slidably brought into contact with the flange portion of the spool and provided with a circular-arc reverse-direction follower-guide portion, a several-turn spiral follower-guide portion, and a spool locking hole, in addition to the conventional seat belt retractor. The follower and guide disk set the slack at a preset tensionless length not requiring resetting when the occupant returns from a forward leaning position.
