  • Patent number: 10723206
    Abstract: A door module for a motor vehicle door having a module carrier which is formed substantially by organic sheet, a longitudinally extending channel which is formed integrally in the organic sheet of the module carrier, an insertion opening which extends along the direction of extent of the channel and via which a reinforcement element of the motor vehicle door is insertable into the channel, and at least one functional element which is fixed to the module carrier and which crosses the channel and thereby partially covers the longitudinally extending insertion opening thereof. In the organic sheet of the module carrier, there is formed an elastically deformable bending region which enables the channel to be bent open at least in sections, and/or enables the channel to be bent away from the functional element, in order to open up the insertion opening of the channel for the insertion of the reinforcement element.

  • Patent number: 6942260
    Abstract: A closing device for a vehicle door includes a doorlock, an operating element for operating the doorlock, an external door handle fixed to the external skin of the vehicle door with an adjuster piece, a deflecting element which translates a movement of the adjuster piece along a first direction into a movement along a second direction and a coupling element by means of which the deflector element acts upon the operating element. The external door handle and the deflecting element are connected to the external skin of the vehicle door, such that they move together with a deformation of the external skin and that the coupling element is provided with means for distance compensation, which permits a movement of the deflector piece relative to the operating element, without the deflecting element acting upon the operating element.

  • Patent number: 6874279
    Abstract: A window lifter includes a rope or a Bowden cable and is used in motor vehicles. The window lifter also includes guide rails that are integrated into the base surface of a carrier plate of a motor vehicle door. The window lifter also includes carriers that can be displaced along the guide rails and receive a window pane as well as reversing devices that are arranged at the ends of the guide rails. The rope engages with the carriers and a drive device and is guided via the reversing devices. The guide rails protrude from the base surface of the carrier plate, have a slot that extends in the longitudinal direction and are covered on the open base side of the carrier plate in a dampproof manner. The carriers can be at least partially situated on the external and internal side of the guide rails and pass through the respective slot to engage with the rails.

  • Patent number: 5946860
    Abstract: A pane guide for a spherically curved window pane which can be lowered in a door shaft of a vehicle door and forms a component part of an imaginary barrel shaped sleeve surface along the longitudinal direction of the vehicle, and which can be moved in the direction of the longitudinal axis of the vehicle by a double-strand cable window lift mounted in the door shaft. The guide rails have a first and second curvature adapted to the window pane curvature in the transverse direction of the vehicle so that a swivel movement about a swivel point spaced from a guide edge of the window pane in the X-direction is additionally superimposed on the displacement movement of the window pane. The imaginary barrel-shaped sleeve face on which the window pane is displaced swivels with the window pane and during the displacement movement between the extreme positions there are always three corner points of the window pane lying on the barrel-shaped sleeve face.
