Abstract: A manual lever drive for an adjusting device on a seat for converting a lifting movement into a discontinuous rotational movement has a support arm and a step-by step mechanism having an output member and an input member. The output member is configured to be coupled with a rotatingly moveable control member of the adjusting device. A transmission member is connected to the input member for torque transmission onto the input member. A manual lever is connected to the support arm so as to pivot about a first axis of rotation. The manual lever is configured to actuate the transmission member. The transmission member is arranged on the input member providing a second axis of rotation. A pivot angle of the manual lever imparts to the transmission member a pivot movement increasing a corresponding pivot angle of the second axis of rotation.

Abstract: A displacement device for use with windows and sliding roof for motor vehicles includes a toothed rack disposed within the vehicle in a direction parallel to the displacement direction. A motor-gear housing is positioned adjacent the toothed rack and includes an electrical driver, a central shaft positioned perpendicular to the rack, and a pinion gear on the shaft that is engaged with the toothed portion of the rack. The rack and housing include guide surfaces that are positioned to correspond with one another. A guidance element is attached to the housing and the rack is interposed between the guide surfaces of the housing and the guidance element to control and guide the movement of the housing vis-a-vis the rack during activation of the electrical drive. Attachments extend from the housing and are configured to accommodate placement of an edge portion of a window therein.
