Adjusting device for a door window pane, frameless and cooperating with a window lifter, of a motor vehicle

An adjusting device cooperating with a window lifter for a door window pane of a motor vehicle having a car body and a door body, comprising:

• at least one guide rail forming a portion of the window lifter, said guide rail extending upright inside the door body and being pivotably mounted around an upper pivot point in a transverse direction of the vehicle;
• wherein said guide rail is lockable by the adjusting device enraging a lower area of the guide rail in a position such that a marginal area of the door window pane abuts under pretension an adjoining seal in the car body;
• a displacement guide provided on the door body for adjusting said guide rail at its lower end in the transverse direction with respect to a door window pane;
• fastening elements associated with the displacement guide for securing said guide rail in the displacement guide in an adjusted position with respect to the motor vehicle, said fastening elements being accessible from an underside of the door body;
• wherein said window lifter comprises at least two guide rails spaced apart and parallel to one another, each of said guide rails having an associated displacement guide;
• and
• wherein each of said displacement guides comprises a receptacle provided on the door body, said receptacle being in active connection with a lower end of said associated guide rail;
• and
• wherein said receptacle includes an upper limiting surface which, viewed in the transverse direction of the motor vehicle, forms an approximate circular arc shape, with a center of said circular arc being located approximately at an intersection of the door panel with a central axis of an upper fastening element of the guide rails, and further wherein a correspondingly shaped wall section of a retaining angle bracket is displaceably mounted on the upper limiting surface of said receptacle.
