Abstract
A progressivity device for a friction clutch disc includes a support flange, having a central axis of rotation, in which an annular central part is designed to cooperate with a torsional vibration damper, and an external part bears progressivity blades and friction pads attached to the progressivity blades. The progressivity blades extend circumferentially over at least one of the faces of the support flange. The progressivity blade include one end fixed to the external part, another free end and folds delimiting a support region for the friction pad.
