Description

The The invention relates to a vehicle door with a window according to the preamble of claim 1.

From the DE 196 54 851 C1 a cable window lifter for motor vehicles is known, comprising a guide rail, a displaceably mounted on the guide rail and a window pane driver, a motor or manual drive unit and for transmitting power from the drive unit to the driver a rope, the one-piece or composed of several cable sections rope loop forms and is wound around a cable drum connected to the drive unit. The cable loop is guided over a respective upper and lower deflection roller along the guide rails of the two drivers and can be arranged at least partially in a Bowden tube. The slidably mounted in the guide rails driver are connected by means of cable nipple with the cable loop, so that upon actuation of the drive unit, the drivers are moved along the guide rails between the deflectors and thereby raise or lower connected to the drivers window in side window guides.

From the EP 1 123 824 A2 a roller blind for a run in guide rails side window of a motor vehicle is known which has a winding shaft which is rotatably mounted behind the side panel of the door or the B-pillar. On the winding shaft a roller blind is wound up, which can be deducted for complete or partial covering of the window of the winding shaft. To the side window roller blind includes a guide rail which is fixed to the door in the region of the front window frame portion and extends from the upper window frame portion to the inside of the door. In the guide rail, a carriage runs with a through a slot of the guide rail projecting outward strip-shaped flange which is connected to a mounted on the upper edge of the roller blind edge reinforcing strip. The carriage is connected via a pressure-resistant, linear element in the form of a flexible metal or plastic wire, the soul of a Bowden cable or a shear-stiff, stranded strand of wire with a reduction gear, which is driven by a drive motor. To wind the roller blind on the winding shaft arranged in the winding shaft spring motor is provided which forms part of the drive means of the side window blinds together with the drive motor and generates a biasing force in the sense of winding the blind sheet on the winding shaft.

in the Hibernation is the roller blind under the action of the spring motor wound on the winding shaft and the carriage in the guide rail after drove down. To extend the side window roller blind, the drive motor set in motion and over the reduction gear the pressure rigid guided linear element shifted so that the roller blind over the strip-shaped flange and the edge reinforcement strip unwound from the winding shaft and pulled up in the door. In this case, the roller blind next to the window using the guide rail or additional pressure or bending stiffness actuators be kept stretched.

The known, installed together with a window in a motor vehicle door Side window blind needed to the leadership the roller blind has its own roller guide rails, the additional to the guide rails of the window regulator in the door shaft the motor vehicle door be installed, as well as a window blind control, which prevents that when opening of the side window the window blind remains closed and through the effect of wind is destroyed.

Of the The present invention is based on the task, a vehicle door of the aforementioned type with a far-reaching integration of To create a rolling mechanism in the window regulator mechanism.

These Task is inventively by the features of the claim 1 solved.

The Solution according to the invention allows a extensive integration of windows and rolling mechanism and thus a reduction of for the rolling mechanism required parts and a corresponding space-saving arrangement of the window regulator and rolling mechanism. Furthermore possible the integration of the rolling mechanism in the functional elements of the Window lift a coupling of the rollover position with the window pane adjustment, so without additional control technical effort closing the blind or a closed roller blind with completely or partially lowered window is avoided.

One Another advantage of the inventive solution is that by the integration of the rolling mechanism in the window regulator guide rail the window blind pre-mounted on the window and thus the final assembly the motor vehicle door simplified can be.

As guided on the window regulator guide rail part of the rolling mechanism is used in a first variant of the solution according to the invention connected to the upper end of the roller blind in the withdrawal direction pressure rod as a power transmission element of the window blinds, which is attached to a connected to the upper, the winding shaft of the rolling mechanism opposite edge of the roller blind pull toggle. The push rod may consist of a tube, a half-round rod or the like with a rigid cross-section. For carrying out the pressure rod through the upper door shaft cover or parapet reinforcement, this has a depression corresponding to the cross section of the pressure rod.

Of the Thus, with the upper edge of the roller blind connected pressure rod can along the window regulator guide rail for winding the roller blind on the winding shaft in the door shaft lowered and along the guide rail for unwinding the roller blind from the winding shaft and for covering the window pane raised from the door shaft be so that a separate leadership of the pressure bar is eliminated.
