A method of assembling a rewind spring in a cassette for a vehicle safety restraint retractor, the method comprising: placing a mechanism cover (1) on a winding jig, fitting an arbor (4) to a winding shaft of the jig, fixing one end of a coiled metal band spring (5) to the spring arbor (4), and the other end to the mechanism cover (1) winding the band onto the arbor in the mechanism cover, fitting a spring cover (7) to the mechanism cover, and attaching a locking clip (6) to the spring cover (7) to lock the arbor against rotation. The spring arbor (4) for use in the cassette has a generally cylindrical shape, an axially extending slot for receiving an end of the spring, and a central transferring hole (14) of a non-circular profile such as a hexagon which cooperates with a central pin in the locking clip (6) and also with the winding shaft on the winding apparatus used in the method. <IMAGE> |
