ABSTRACT:
Winder safety device comprising a manually operable knob which is provided with a stem rotatably associated with a supporting element, provided on a portion of a ski boot, to said supporting element being pivoted coaxial with the stem a winder of at least one elastic traction element lockable against rotation by external locking mean. A drive wheel is keyed to the knob for rotation therewith and free to slide axially with respect to the stem, the drive wheel is provided with a first gear which meshes unidirectionally with a facing second gear rigidly associated with the winder. The configuration of the first gear and of the second gear is such that the two gears engage without meshing with each other upon a rotation opposite to the winding of said at least one traction element.
