Abstract
A cable tensioner comprising a winding drum (2) driveable in rotation by means of a handle (12) by the agency of a pinion (10) meshing with a gear wheel (7). The pinion (10) forms part of a non-return device (13, 14). Pressure on the handle (12) releases the drum of the non-return device. According to another embodiment, the non-return device is composed of a worm gear and the drum is released by shifting this.

A cable tensioner with a winding drum for a ski boot, comprising, in a housing (1;
- 28), a winding drum (2;
- 25) equipped with a toothing (7;
- 32) a rotatable external handle (12;
- 27) shiftable axially counter to the action of a spring, and a non-return device (10, 13, 14;
- 29, 30) preventing the drum from rotating in the unwinding direction, this non-return device being cancellable as a result of pressure on the handle, wherein the cancellable non-return device is composed of a set of movable elements (10, 13, 14;
- 29, 30), one (10;
- 29) of which meshes with the toothing of the winding drum, one (10;
- 30) of these movable elements also being driveable in rotation by said external handle for driving the winding drum.
