ABSTRACT:
A self-locking winder for a safety belt comprising a mandrel (5) rotatively mounted in a support (1) and on which is wound the strap of the belt, the mandrel being biased by a torsion spring (63) in the winding direction, and a locking device (16, 19, 28). The latter locks the mandrel against rotation in the event of impact and prevents the unwinding of the strap. The mandrel comprises a sleeve (6) of moulded plastics material in which is mounted a metal reinforcing bar (9). A reel (11) is mounted on the sleeve and receives the strap. The sleeve is directly journalled in the support.
