ABSTRACT:
The winder is of the type comprising a support structure (1) in which is rotatively mounted a reel connected to safety and locking means for the strap (5) and to means (4) for returning the strap to the position in which it is wound on the reel. The return means comprise a cylindrical housing (6) which is mounted to be rotatable about the axis of rotation of the reel and in which is disposed a spiral spring (7) for putting the strap (5) under tension. The spring has one end fixed to the shaft of rotation of the reel and the other end mounted on the housing (6). The housing (6) cooperates with an intermediate pinion (10) which is meshed with a pinion (11) fixed to the output shaft of an electric motor (12). The motor and the intermediate pinion (10) are carried by a plate (13) which is mounted to be angularly movable about the axis of rotation of the reel between a position for deactivating the electric motor and a position for activating the latter, and therefore the winding of the strap on the reel, in response to a slackening of the tension imparted to the spring (7) by the strap (5).
