Abstract: A device for connecting component parts, such as entrainment members, to a support element of a motor vehicle door, wherein the support element has at least one protrusion therein for the positive-locking hold of the entrainment members. In one embodiment two protrusions are provided forming guide rails for entrainment members of a window pane of a cable or Bowden cable window lifter. The two protrusions are imprinted in a support plate whereby the guide rails and the support plate are preferably a one-piece structural unit of a motor vehicle door.

Abstract: Device for transferring mechanical setting movements and/or electrical signals between a door operating device (3) and a door closing device (4) of a motor vehicle door for the mechanical door functions opening/closing and locking/unlocking as well as for electrical lock functions. A one-piece coupling element (5) which is capable of translation and/or rotational displacement and which mechanically and/or electrically transfers both door functions between the door operating device (3) and the door closing device (4) is provided with at least one plug which can be connected to an electrical contacting site mounted on the door closing device (4) or on the support plate, wherein the control signals for both door functions can be transferred through the electrical contacting site or the control signals for one door function can be transferred through the electrical contacting site whilst the other door function can be transferred rotationally or in translation through the coupling element (5).

Abstract: A motor vehicle door including a simple latch assembly comprising a preassembled and easily inspectable functional module and a moisture barrier which separates a dry zone sealed from external moisture and an unsealed wet zone. The latch lies completely within the dry zone. The latch is preassembled on the side of a mounting plate facing an inside door panel and includes a sealing element which seals at least a portion of the latch area against moisture.
