Description

[0012] Further advantages and features of the invention can be gathered from the claims and from the following description of a preferred exemplary embodiment of the invention which is illustrated by the drawings.

[0013] FIG. 1 shows a schematic perspective illustration of an embodiment of a motor vehicle door, according to the invention, for a passenger car, and

[0014] FIG. 2 shows a schematic view of a carrier module for the motor vehicle door according to FIG. 1.

[0015] A motor vehicle door 1 according to FIG. 1 is provided for a passenger car. The motor vehicle door 1 is a rear side door of the passenger car in the exemplary embodiment illustrated. The motor vehicle door 1 has, above a door interior breastwork 7, a window arrangement 2 which is accommodated in a window frame 4 of a door body structure 3. At least one window of the window arrangement 2 can be embodied so as to be lowerable in the door body structure 3. On the inner side of the door, the window arrangement 2 is assigned a shading device B which can be seen in FIG. 2. The shading device B is integrated in a dimensionally stable carrier module 5 which is fastened from a door inner side to the door body structure 3 in the region of the window frame 4 and at the height of the door interior breastwork 7. In the region of the window arrangement 2, the carrier module 5 has two cutouts which are coordinated with the dimensions of the window arrangement. The cutouts are surrounded by frame portions which are coordinated with corresponding frame portions of the window frame 4. The frame portions are integral constituents of the carrier module 5, which is embodied as an integral, dimensionally stable plastics component in the exemplary embodiment illustrated.

[0016] In the region of an underside of the cutout for the larger window of the window arrangement 2, the carrier module 5 has a movable closing part 6 which is designed as a flap mounted in a pivotable manner on the carrier module 5. The closing part 6 is provided in the region of a top side of the door interior breastwork 7 and extends substantially along the entire length of the larger window of the window arrangement 2as seen in the longitudinal direction of the vehicle. In the closed position, the closing part 6 closes a passage through which a shading structure 9 of the shading device B can be extended upward. The shading structure 9 is held in a windable and unwindable manner on a winding shaft 13 which is mounted in a rotatable manner at two mounting points (not illustrated) of the carrier module 5. The winding shaft 13 is mounted on the carrier module 5 on the inner side, i.e. on a side facing the door body structure 4. Likewise on this inner side, a drive motor 14 of a drive system is fastened to the carrier module 5, said drive motor 14 driving two drive transmission means 15 in the form of thread pitch cables synchronously with one another via a transmission which is not designated further. To this end, the two thread pitch cables 15 are assigned worm gears which are arranged on a common axis, specifically on opposite end sides of the winding shaft 13. The worm gears are oriented coaxially with the axis of rotation of the winding shaft 13. In the exemplary embodiment illustrated, the winding shaft 13 is embodied as a synchronization shaft for the two worm gears, such that driving via the drive motor 14 inevitably brings about rotation of the two worm gears and accordingly a longitudinal displacement of the two thread pitch cables 15. The drive motor 14 is embodied as an electric motor. The thread pitch cables 15 are laid in guide rails 12 in frame portions of the carrier module 5, wherein the guide rails 12 extend substantially in the vertical direction of the vehicle on opposite sides of the cutout for the larger window of the window arrangement 2. The guide rails 12 are either formed integrally in the manner of slot-like profiles in the carrier module 5, or the guide rails 12 are fastened as separate guide profiles to the inner side of the carrier module in the region of the frame portions. A guide member 11 is guided in a linearly movable manner in each of the guide rails 12. The guide members 11 are assigned to opposite end sides of a dimensionally stable extension profile 10 which is fastened to a front end region, in the extension direction, of the web-like shading structure 9. The extension profile 10 is displaceable in a parallel manner between a rest position, lowered in the passage that is closeable by the closing part 6, and a functional position which has been traveled to upward as far as an upper frame portion of the carrier module 5, in that the guide members 11 are moved along by means of the thread pitch cables 15 in the guide rails 12. All of the functional components of the shading device B, i.e. the winding shaft 13 with the shading structure 9 and the extension profile 10, the guide rails 12, the guide members 11, the thread pitch cables 15 and further components of the drive system such as the drive motor 14 and the associated transmission with the worm gears, are arranged on and fastened to the inner side of the carrier module 5 via corresponding fastening or mounting points. Inner side should be understood as meaning, with regard to the carrier module 5, the side that faces away from the vehicle interior toward the door body structure 3 with the window frame 4. On the opposite side, facing the vehicle interior, the carrier module 5 is provided with a surface coordinated with the vehicle interior trim, said surface being able to be provided with an interior trim arrangement in the form of a coating and/or covering, wherein the interior trim arrangement is coordinated esthetically and in terms of design with the rest of the vehicle interior trim.

[0017] The carrier module 5, including all of the functional components of the shading device B, is able to be preassembled in a functional manner before the carrier module 5 provided with the shading device B is attached to the inner side of the door body structure 3, 4. To this end, the carrier module 5 has a plurality of holders, which are not discernible in FIGS. 1 and 2. The holders can be formed by mechanical latching arrangements and/or by additional fastening arrangements that are operable by means of a tool, said arrangements each being provided in a complementary manner in the region of the door body structure 3 including the window frame 4 and in the region of the carrier module 5. If the holders are formed by latching arrangements, it is advantageously possible to connect the fully preassembled carrier module 5 to the door body structure 3 without tools in that the carrier module 5 is latched together with the door body structure.

[0018] In the exemplary embodiment illustrated in FIGS. 1 and 2, the carrier module 5 extends only over an upper region of the door body structure 3, i.e. substantially over the height and width of the window frame 4 and the window arrangement 2 down to the height of the door interior breastwork 7. In an exemplary embodiment (not illustrated) of the invention, the carrier module extends over the entire height and width of a door body structure, i.e. as far as a lower end region of the door body structure. In this way, the carrier module forms a complete inner side of the motor vehicle door.

[0019] As soon as the carrier module 5 has been mounted on the door body structure 3, all that is then necessary is to connect power supply and control lines 16 for the drive system of the shading device B to an on-board power supply system of the vehicle and a controller of the vehicle in order to prepare the shading device B in an operational manner.
