Abstract
The winding device includes a solar pinion mounted for free rotation in a coaxial manner about a central arbor on a winding wheel. The device also includes toothed planetary wheels for meshing with a toothing of the solar pinion. The planetary wheels are mounted for free rotation with play about a respective offset arbor fixed to the winding wheel. The device also includes one or two hooks of a frame fixedly mounted on the winding wheel. In a first direction of rotation of the solar pinion, a planetary wheel is in a locking position in contact with a hook in order to drive the winding wheel. In a second direction of rotation opposite to the first direction of rotation, the planetary wheel is uncoupled so that the rotation of the solar pinion does not drive the winding wheel.
