Description

Field of the invention

The present invention relates to a sun screen for window panes of vehicle doors according to the preamble of claim 1 and a function carrier for receiving a sun blinds and a method for mounting a sun blinds on a vehicle door.

State of the art

Sunscreen blinds for windows of vehicle doors usually include a roller screen covering the window pane, a winding shaft for receiving the roller blind, a roller blind adjustment mechanism for winding the roller blind on the winding shaft and unwinding of the roller blind from the winding shaft and lateral guide rails for the roller blind.

It is known to attach the items to the window frame and / or on a shell construction armor. From the DE 203 10 943 U1 For example, it is known to integrate at least the winding shaft in the shell in the door body. However, this has the disadvantage that the assembly of the sun blinds is shifted to the vehicle door in cost-intensive areas of manufacturing.

It is further known, for example from the DE 600 02 837 T2 To design vehicle doors with function carriers. These function carriers are sometimes referred to as modules or door modules. Certain devices and / or functions can be preassembled on the function carrier.

For example, it is known to pre-assemble a roller blind cassette on the function carrier. The lateral guide rails of the sun blinds are placed in the final assembly, for example, the Original Equipment Manufacturer (OEM), on the roller blind box and bolted to the window frame. However, this has the disadvantage that certain interfaces between roller blind box and guide rails are provided. Furthermore, certain functional tests of the roller blind can only be carried out after or during the final assembly. The delivery of the sun blinds for final assembly in individual parts also has an increased logistical effort and thus increased costs as a result.

The DE 92 169 63 U1 further describes a roller blind device, in which two guide rails each have a joint, so that these guide rails for the purpose of transport at least partially 90 ° can be pivoted to then be arranged parallel to the roller blind. As a result, however, especially the packaging of the roller blind device is facilitated, the need for readjustment after installation is not eliminated thereby.

Presentation of the invention

It is therefore the object of the present invention to provide a sun screen for window panes of vehicle doors, wherein the sun visor is preassembled with at least one guide rail on a vehicle carrier and in the preassembled state, a simple transport is possible and the installation is facilitated. It is another object of the present invention to provide a flexible and inexpensive method for mounting a sun blinds on a vehicle door.

This object is achieved by the objects having the features of claims 1 and 14.

For this purpose, in a sun screen for window panes of vehicle doors, comprising a window pane at least partially covering roller blind, a winding shaft for receiving the roller blind and a roller blind adjustment mechanism for winding the roller blind on the winding shaft and unwinding of the roller blind provided by the winding shaft, characterized by a function carrier for receiving the sun blinds and at least one guide rail for guiding the roller blind when winding and / or unwinding, wherein the guide rail is mounted on the function carrier and is arranged to be movable at least between a transport position and an installation position about the winding shaft. The guide rail is thereby mounted in a pre-assembly on a function carrier. In the installation position, the sunshade can be mounted on an associated vehicle door. If the guide rail were conventionally preassembled on a function carrier, it would be in the installed position of this. The transport of the function carrier with premoritated guide rail would therefore be unwieldy. According to the invention, by a movement of the guide rail about the winding shaft into a transport position, a space requirement of the function carrier with at least partially pre-assembled sun protection roller and / or handling of the function carrier with at least partially pre-assembled sun protection roller can be improved.

For the purposes of the invention, vehicle doors are not restrictive as to understand pivoting about a side axis doors, but it may also be so-called flaps and / or other movable or immovable vehicle parts with windows.

Preferably, at least in the installation position of the sun blinds a Function test possible during pre-assembly. The functional test is thus possible before mounting the sun blinds on the associated vehicle door. For this example, all the necessary parts of the sun blinds are already mounted in the pre-assembly on the function carrier without the parts for transport after the functional test must be dismantled again. For example, the roller blind can be extended and retracted for testing purposes for the functional test. It can also be made any necessary adjustments. After completion of the functional test, the guide rail is movable into the transport position. If the sunshade as a whole can be preassembled on the function carrier, then all settings and / or functional tests in the pre-assembly can be carried out.

In a preferred embodiment, the guide rail (s) is or are pivotable at least between the transport position and the installation position. In addition, a displacement of the guide rail is conceivable. However, a pivotable design of the guide rail has the advantage that the movement is more independent of a geometry of the function carrier. Possibly from the function carrier outstanding, also in the pre-assembly already integrated components interfere with the pivoting or folding movement. In addition, a cost-effective training is possible because the pivoting or folding movement corresponds to the relative movement for winding and unwinding of the roller blind.

Preferably, the sunshade is formed with a rear and a front guide rail, which are pivotally mounted relative to the winding shaft. Two lateral guide rails provide stable guidance of the roller blind.

Particularly preferably, the front and the rear guide rail are connected by means of a cross bar. As a result, the stability of the preassembled sun blinds can be improved.

Preferably, the at least one guide rail is mounted directly pivotably on the winding shaft. The guide rail is thereby pivotable about the winding shaft. The direct storage on the winding shaft is particularly cost feasible. In addition, initial functional tests are already possible before mounting on the function carrier. Winding shaft and guide rails are transported as a unit to a pre-assembly.

In a further embodiment, the guide rail is mounted on the function carrier. The guide rails are thereby mounted independently of the winding shaft and / or other elements of the sunscreen on a function carrier. The guide rail can in particular be mounted on the function carrier in such a way that it is pivotable about the winding shaft.

In a further embodiment, the roller blind adjustment mechanism comprises a cable drive. This design is particularly advantageous because the cables of the cable are wound and / or unwound on a cable drum or a conical reel, so that the relative movement corresponds to the rotation of the winding shaft. In addition, a drive with pitch cable is conceivable.

Preferably, the roller blind adjustment mechanism further comprises a drive motor. In addition, however, it is also conceivable that the sunshade is manually operated. The drive motor thus works in combination with a cable drive, a pitch cable and / or similar displacement mechanisms.

Particularly preferably, the at least one guide rail can be fixed in the transport position on the function carrier. Through this transport lock the handling of the function carrier during transport is further improved.

Preferably, a further sun blind is pre-mounted on a guide rail. In particular, it may be a sun screen for a so-called triangular window. The additional sun blind is formed in a first embodiment with a separate winding shaft, which is pre-mounted on a rear guide rail and / or on the function carrier. In a further embodiment, the winding shaft of the first sun blind is continued in a further window area, for example a triangular window area. The extension of the additional roller blinds is done either from the front to the back or from bottom to top depending on the requirement and the embodiment. The function of the additional sun blinds is also verifiable before final assembly.

In a further embodiment, the winding shaft of the sun protection roller blind is designed as a traveling wave. By traveling waves an adaptation to a disk geometry is possible. When extending the sunblind, the traveling wave moves in the axial direction and adapts to the changing width of the sun blinds.

The function carrier for receiving the sun blinds is formed at least with receiving and / or fastening means for a pre-assembly of the winding shaft on the function carrier. On the function carrier is thus for example a Winding shaft pre-assembled, wherein guide rails are pivotally mounted on the winding shaft.

In a further embodiment, the function carrier further comprises a bearing for the at least one guide rail. The guide rails are characterized on the function carrier independently of the other elements of the sun blinds movably fastened.

In a further embodiment, the receiving and / or fastening means for the winding shaft is designed as a roller blind box. Through the roller blind box, the roller blind is well estimated against mechanical stresses. The roller blind box can be formed for example by the function carrier itself.

For the installation of the sun blinds, the sun blind is at least partially pre-assembled on the function carrier in a first step. In a further independent step, the function carrier is fastened to a vehicle body. The pre-assembly of the sunblind on the function carrier is thus independent of the mounting of the function carrier on the vehicle door. The installation of the sun blinds can be carried out at a suitable time in the production.
