Abstract
A winding device, in particular for a barrel provided with a spring, including a ratchet fixedly mounted on a rotary winding shaft, the rotary winding shaft being, for example, a winding shaft of the barrel, the rotation of which winds the barrel, and a winding gear train meshing with the ratchet, the rotation of the winding gear train causing the ratchet to rotate and the rotary winding shaft to rotate by applying a torque to the ratchet, the winding gear train being movable between a coupled position wherein it drives the ratchet and a disconnected position wherein it does not drive the ratchet, the winding gear train being mounted on a spring exerting a return force on the winding gear train to keep it in the coupled position. A horological movement can include such a winding device.
