<p>The invention relates to a vibration damper for a torque transmission device including a first element (1) and a second element (2) that are rotatable relative to one another around an axis of rotation X; and damping means to transmit a torque and damp the rotational acyclisms between the first element (1) and the second element (2). The damping means include an elastic blade (4) mounted secured to the first element and provided with a cam surface (6); and the damper includes a cam follower (5) supported by the second element and arranged to cooperate with said cam surface (6). The cam surface (6) is arranged such that for an angular travel between the first element (1) and the second element (2) relative to an angular idle position the cam follower (6) exerts a bending force on the elastic blade (4) producing a reaction force capable of recalling said first (1) and second (2) elements toward said angular idle position.</p> |
