Date Jan. 3, 1997A torsion damping device is disposed between two rotating elements, namely an input element (1) and an output element (2), the device comprising, firstly a main damper (10) referred to as a first damper and having circumferentially acting first resilient member (11), the first damper being directly acted on kinematically by the input element and secondly, a second predamper (20) having circumferentially acting second resilient members (21), the second damper being placed directly upstream of the output element (2). The device further includes an intermediate third damper (30) which is disposed kinematically between the first damper (10) and the second damper (20), the third damper (30) includes circumferentially acting third resilient members (31) the stiffness of which has a value intermediate between the stiffnesses of the first resilient members (11) and second resilient members (21) respectively.
