The mechanism has a locking device comprising a lever (14), and an anti-reversibility device comprising a cam (16) with a support surface (17). The surface tangentially makes contact with a support surface (15) of the lever. The surface (17) has teeth (18) defining channels and forming protrusions with a height between 0.02 and 0.5 millimeters. Lines of channels are spaced from each other with a distance between 0.1 and 1 millimeters. The protrusions contact the surface (15) when the cam is in an active position and present a hardness greater than that of the surface (15). |
