  • Patent number: 9051978
    Abstract: A clamping roller freewheel for an adjusting device in a motor vehicle includes a cylindrical outer surface, at least one roller pair, an output shaft, a clamping element which is rotationally connected to the output shaft and which has at least one clamping slope on an opposite side of the roller pair to the cylindrical outer surface, and a spacer device which is at least partially between the rollers and has elastic properties. This spacer device includes a spacer piece and a spring. When the spacer piece is in the normal position, an oblique surface bears against a roller. The spring presses the spacer piece into the normal position in which it exerts a force on at least one roller. When passing from the normal position to the retracted position, the oblique surface is moved away from the roller.

  • Patent number: 8720661
    Abstract: A clamping-roller freewheel for an adjustment device in a motor vehicle includes a housing, a cylindrical lateral surface that defines an axis, at least one roller, an output shaft that is central to the axis, and a clamping contour which is located on the side of the roller opposite from the cylindrical lateral surface and rotationally connected to the output shaft. The clamping contour is a double clamping contour. The roller is allocated to the double clamping contour. The double clamping contour has a left and a right clamping area. A clamping action arises due to the cooperation of the roller with the left or right clamping area, depending on the direction of rotation, and the cylindrical lateral surface.

  • Patent number: 7069811
    Abstract: An actuation device of an adjustment unit for automotive vehicle seats has a hand lever and a frame. The frame carries the hand lever and accommodates an output shaft. The hand lever adopts a central position when the actuation device is in a position of rest, and may be pivoted alternatively in the two directions of rotation against the action of an elastic means biasing it in the central position. The hand lever has a first driving region. An adjustment wheel having circumferential gear teeth is centred on the output shaft. A pivotal lever has a long hole surrounding the output shaft, has a left engagement region and a right engagement region substantially extending as a continuation of the long hole. These regions are both provided with teeth matching the gear teeth of the adjustment wheel and being disengaged from the teeth of the adjustment wheel in the position of rest of the actuation device.
