A rewind spring in a cassette for a seat belt retractor is assembled by first placing a mechanism cover on a winding jig. An arbor is fitted to a winding shaft of the jig. One end of a coiled metal bank spring is then fixed to the spring arbor. The band is then wound onto the arbor in the mechanism cover and a spring cover is fitted to the mechanism cover. Finally, a locking clip is attached to the spring cover to lock the arbor against rotation. A spring arbor for use in the cassette has a generally cylindrical shape and an axially extending slot for receiving an end of the spring. A step is provided in the profile of the cylindrical outer surface of the arbor in the region of the slot to compensate for the thickness of the band wound thereon.
A method of assembling a rewind spring in cassette for a seat belt retractor, the method comprising the steps of:
A locking clip for locking a spring arbor against rotation in a pre-wound retractor spring cassette for a seat belt retractor, the clip comprising a pin having an outer profile complimentary to the inner profile of the arbor.
