  • Patent number: 7958800
    Abstract: An actuation device is provided for actuating a traction element (5), the actuation element comprising in particular a pivotally mounted force transmission element (1) for transferring an actuation force to the traction element (5). The force transmission element comprises first stop means (7), the actuation device further comprises second stop means (9), whereby a possible angle of rotation of the force transmission element (1) is limited. The first stop means (7) and/or the second stop means (9) comprise(s) a resilient element. A stop is thereby dampened and when the first stop means (7) butts against the second stop means (9) energy absorbed by the resilient element (7) can be used to assist a movement of the force transmission element (1) in an opposite direction.
