Friction system for a horology movement

A horology movement comprising a friction system, said friction system comprising:

• an arbor with a longitudinal axis designed to be mounted in the horology movement;
• a first fixed element, mounted so as to rotate integrally with the arbor;
• said first fixed element having a first support surface;
• a second fixed element mounted so as to rotate integrally with the arbor;
• a toothed organ, mounted so as to rotate freely on the arbor between the first fixed element and the second fixed element;
• wherein the toothed organ is integral with a socket coupling having a second support surface, and in that the second fixed element comprises a body configured to rotate integrally with the arbor, and resilient brackets protruding relative to the body and extending towards the toothed organ, said resilient brackets being resiliently pressed against said second support surface of the socket coupling, said resilient brackets being designed to distort resiliently under strain from the second support surface and to form a kinematic linkage both between the first fixed element and the toothed organ and between the second fixed element and the socket coupling integral with the toothed organ up to a predetermined friction torque.
