1. A hydrokinetic torque coupling device for a motor vehicle comprising a torque input element (11) intended to be coupled to a crankshaft (1), a turbine wheel (4), an impeller wheel (3) rotationally coupled to the torque input element (11) and able to hydrokinetically drive the turbine wheel (4), a torque output element (8) intended to be coupled to a transmission input shaft (2), damping means (21, 25), clutch means (10) adapted to rotationally couple the torque input element (11) and the torque output element (8) in an engaged position, through the damping means (21, 25), and able to rotationally uncouple the torque input element (11) and the torque output element (8) in a disengaged position, with the damping means (21, 25) being adapted to act against the rotation of the torque input element (11) relative to the torque output element (8), in the engaged position of the clutch means (10), with the damping means (21, 25) comprising at least an elastic blade (25) which rotates together with the torque output element (8) or the clutch means (10) respectively, and a supporting member (21) carried by the clutch means (10) or the torque output element (8) respectively, with the blade (25) being elastically maintained supported by said supporting member (21), with said elastic blade (25) being adapted to bend upon rotation of the torque input element (11) relative to the torque output element (8), in an engaged position, with the supporting member (21) or the elastic blade (25) respectively being mounted on at least one supporting flange (20) so mounted as to pivot on the torque output element (8) through a bearing (18) such as a ball bearing for instance. |
