Abstract
Description
[0001] The invention relates to an integrated electric drive mechanism for an electric shading device for motor vehicles, in particular an integrated electric drive mechanism for integrating an electric shading device for a side window and an electric shading device for a triangular window, with which drive mechanism a side window shading strip and a triangular window shading strip for these two electric shading devices can be extended and retracted in the coupled state.
[0002] In accordance with the bodywork of a motor vehicle, conventional vehicle windows on the rear doors are designed such that the window consists of a side window with a tiltable pane and a triangular window with a fixed pane located behind the side window. To ensure that the side window and the triangular window also provide sun protection for the vehicle interior, a shading strip is usually attached to the side window and a shading strip to the triangular window.Conventional electric window shades designed for vehicle mounting consist of a shade strip that can be wound and unwound by a winding shaft unit. A side strip is provided on one side of the shade strip, with both ends connected to a motor unit via a flexible transmission element. This flexible transmission element, driven by the motor unit, causes the side strip of the shade strip to move. The winding shaft unit provides the force for automatic winding and unwinding, allowing the shade strip to be extended and retracted. Thus, the side window shade and the triangular window shade each require their own separate electric drive mechanism, resulting in a complex system and significant costs.
[0003] To simplify and integrate the electric drive mechanisms for the side window shading strip and the triangular window shading strip into a single unit, a shading device for a motor vehicle side window has been proposed in CN 112829552 B. The shading device comprises a main blind (i.e., a side window shading strip), a secondary blind (i.e., a triangular window shading strip), and a drive system. The main blind is connected to a transversely extending, rotatable winding shaft, with an extension element (i.e., a plate on the movable side of the side window shading strip) arranged on the side of the main blind where it is extended.To extend or retract the main curtain, the two ends of the extension section move vertically up and down in a first and a second guide rail inside the vehicle, allowing the main curtain to be extended upwards or retracted downwards. The secondary curtain is located at the rear of the main curtain and is connected to a longitudinally running, rotatable winding shaft, allowing the secondary curtain to be extended and unfolded transversely. The main curtain and the secondary curtain are therefore extended in different directions, and their extension lengths also differ. An extension disc (i.e., a pulley) is located on the side of the secondary curtain from which it is extended.a strip on the movable side of the rotating corner disc shading strip) arranged, which is equipped with a lever element, wherein a support is provided at the lower end of the lever element, which is mounted in a transverse, arcuate third guide rail and is thus simultaneously displaceable in the longitudinal direction during the transverse displacement in the arcuate third guide rail.
[0004] The aforementioned drive system comprises a flexible drive / transmission assembly and an electric motor. The flexible drive / transmission assembly extends longitudinally and is located in the area of the first, second, and third guide rails. The flexible drive / transmission assembly is driven by the electric motor and includes a cable pull system comprising two cable drums and a driver. The two cable drums are each assigned to a first and second cable pull element for the first and second guide rails of the main curtain, respectively. Additionally, the second cable pull element of the second guide rail of the main curtain is deflected to the third guide rail of the secondary curtain. The driver is assigned to the second cable pull element and is designed to support or release the lever element of the secondary curtain according to the position of the second cable pull element.Thus, the electric motor of the drive system powers the cable elements of the flexible drive / transmission assembly in such a way that the extension part of the main curtain and the lever element of the secondary curtain are moved, thereby extending or retracting the main curtain and the secondary curtain. Because the driver is assigned to the second cable element, the driver can, according to the position of the second cable element, engage or disengage the lever element of the secondary curtain, thus delaying the point at which the secondary curtain is driven and extended.
[0005] The shading device for a motor vehicle side window disclosed in CN 112829552 B can indeed drive the main and secondary blinds with a single drive system, thereby causing them to extend or retract. However, the arrangement of the cable elements presents the following problems. The second cable element of the second guide rail of the main blind is deflected and arranged so that it extends along a transverse guide element and is connected to the drive mechanism. Furthermore, the second cable element is connected to the support of the lever element, which projects into the third guide rail, and passes the distal end of the third guide rail. At this point, the second cable element is deflected and then wound onto the drum.With the conventional shading device of the type mentioned above, the routing of the second cable element is complex and lengthy, requiring considerable effort and time for its installation in a vehicle. Furthermore, the second cable element is deflected at several points, resulting in a considerable length that can easily lead to errors or uneven movements during transmission.
[0006] The invention is based on the objective of creating an integrated electric drive mechanism for a side window shading system and a triangular window shading system, with which drive mechanism the shortcomings mentioned in the prior art are eliminated.
[0007] The object of the invention is achieved by an integrated electric drive mechanism for a side window shading strip and a triangular window shading strip with the features of claim 1. Advantageous embodiments are the subject of the dependent claims.
[0008] The integrated electric drive mechanism according to the invention for a side window shading strip and a triangular window shading strip can be mounted on a vehicle door of a motor vehicle. The drive mechanism serves to drive a side window shading strip that can be extended and retracted vertically and a triangular window shading strip located laterally to the side window shading strip that can be extended and retracted transversely, such that the side window shading strip and the triangular window shading strip are coupled to each other. The two ends of a side plate of the side window shading strip can be driven so that they move up and down along two vertical guide rails on both sides of the side window.The triangular disc shading system is equipped with a side strip connected to a swing arm. The swing arm, with a carriage located at its lower end, moves transversely along a guide rail in the lower part of the triangular disc. The integrated electric drive mechanism for a side disc shading system and a triangular disc shading system comprises: - a motion guide arranged transversely between the lower ends of the two vertical guide rails and corresponding to the end part of the transverse guide rail to which the motion guide adjoins, wherein the motion guide has a shading track motion path that corresponds to the extension path of the side window shading track, wherein the end of the shading track motion path furthest from the transverse guide rail is a starting point of the motion path and the end of the shading track motion path towards the transverse guide rail is an end point of the motion path, wherein a coupling switching point is provided between the starting point and the end point of the motion path, wherein the section between the coupling switching point and the end point of the motion path is defined as the coupling section,wherein the length of the coupling section corresponds to the travel length of the slide in the transverse guide rail; - a drive assembly comprising an electric motor, a first cable pull and a second cable pull, wherein the first and second cables are driven by the electric motor and can move the two ends of the side plate synchronously downwards and upwards in the two vertical guide rails, the first cable pull running in the motion guide; and - a clutch transmission assembly comprising a clutch transmission element and a coupling element, wherein the clutch transmission element can be moved forwards and backwards by the first cable pull on the shading track motion path of the motion guide, wherein the coupling element is displaceable in the coupling section of the motion guide and the transverse guide rail and is connected to the slide located in the transverse guide rail.
[0009] During the process in which the clutch mechanism is driven and thus moves between the starting point and the end point of the shading track's path of travel, the clutch mechanism moving in the forward direction can engage with the coupling element and move in the coupled state, thereby extending the triangular disc shading track and the side disc shading track in the coupled state. The clutch mechanism moving in the reverse direction can disengage from the coupling element at the clutch engagement point, thereby retracting the triangular disc shading track and, once the triangular disc shading track is fully retracted, further retracting the side disc shading track.
[0010] The integrated electric drive mechanism according to the invention for a side window shading system and a triangular window shading system offers the following advantages. By means of the motion guide, the drive mechanism is mounted transversely between the lower ends of the two vertical guide rails in such a way that it abuts and corresponds to the transverse guide rail. The first and second cables, which can be driven by the electric motor in the drive assembly, can synchronously move the two ends of the side plate of the side window shading system up and down in the two vertical guide rails.The clutch assembly comprises a clutch element and a coupling element, wherein the clutch element can be moved forwards and backwards along the path of the shading track by the first cable pull, and the coupling element can move within the coupling section and the transverse guide rail. Furthermore, the coupling element is connected to the carriage located in the transverse guide rail at the lower end of the rocker arm of the movable side strip of the triangular disc shading track.During the process in which the clutch mechanism is driven and thus moves between the starting point and the end point of the shading track's path of travel, the clutch mechanism moving in the forward direction can engage with the coupling element and move in the coupled state, thereby extending the triangular disc shading track and the side disc shading track in the coupled state. The clutch mechanism moving in the reverse direction can disengage from the coupling element at the clutch engagement point, thereby retracting the triangular disc shading track and, once the triangular disc shading track is fully retracted, further retracting the side disc shading track.
[0011] This allows a side window shading system and a triangular window shading system to be extended and retracted by a single drive unit while coupled together. The extension and retraction paths of the side window shading system and the triangular window shading system are coordinated by coupling the clutch gear element and the coupling element of the clutch gear assembly, and by limiting the position and travel of the coupling element. Furthermore, the first cable only needs to be connected to the clutch gear element and is guided in the vertical guide rails and the movement guide. It is connected to the drive unit, but does not need to be guided in the transverse guide rail of the triangular window shading system.This simplified cable routing ensures easy assembly, reduces working time and at the same time reduces the number of cable deflection points in the entire mechanism, thereby ensuring smooth extension and retraction movements of the side window shading strip and the triangular window shading strip and avoiding the risk of movement errors.
[0012] The invention is described in detail below with reference to an exemplary embodiment and the drawing. The drawings show: Fig. 1 a planar view to illustrate a preferred embodiment of an integrated electric drive mechanism according to the invention for a side window shading track and a triangular window shading track, wherein the drive mechanism is mounted between the side window shading track and the triangular window shading track and the side window shading track and the triangular window shading track are retracted, Fig. 2 a front and planar view to illustrate a section of the preferred embodiment in Fig. 1, showing components, including the clutch transmission assembly, Fig. 3 a side and sectional view to illustrate a section of the preferred embodiment in Fig. 1 and Fig. 2, Fig. 4 a planar view to illustrate a section of the preferred embodiment in Fig. 1.

[0013] The following section explains the tasks, features, and advantages of the present invention in more detail with reference to exemplary embodiments and the accompanying drawing. The invention is not intended to be limited to the features described in the description and shown in the drawing.
[0014] In Fig. 1 and Fig. Figure 8 shows a preferred embodiment of an integrated electric drive mechanism 3 according to the invention for a side window shading strip 10 and a triangular window shading strip 20. The drive mechanism 3 can be mounted on a vehicle door of a motor vehicle. The drive mechanism 3 serves to drive a side window shading strip 10 on a side window and a triangular window shading strip 20 located laterally to the side window shading strip 10 on a triangular window of the vehicle door, such that the side window shading strip 10 and the triangular window shading strip 20 are coupled to each other, wherein the side window shading strip 10 can be extended and retracted in the vertical direction and the triangular window shading strip 20 can be extended and retracted in the transverse direction.The area of the triangular disc is smaller than the area of the side disc, so the entry and exit path of the triangular disc shading strip 20 is shorter than the entry and exit path of the side disc shading strip 10.
[0015] As in Fig. 1 and Fig. As shown in Figure 3, the side window shading strip 10 is connected to a winding shaft unit 13 and can be automatically wound up by the winding shaft unit 13. The winding shaft unit 13 for a side window shading strip is arranged transversely in the lower area of a side window. A vertical guide rail 12 is arranged on each side of the side window. The two ends of the side panel 11 of the side window shading strip 10 can be driven to move up and down along the two vertical guide rails 12. The triangular window shading strip 20 is connected to a winding shaft unit 25 for a triangular window shading strip and can be automatically wound up by the winding shaft unit 25.The winding shaft unit 25 for a triangular disc shading strip is arranged longitudinally on a vertical column between the triangular disc and the side disc. A transverse guide rail 24 is arranged in the lower region of the triangular disc. The triangular disc shading strip 20 is equipped with a side strip 21, which is connected to a rocker arm 22. The rocker arm 22, with a carriage 23 located at its lower end, moves transversely along the transverse guide rail 24 in the lower region of the triangular disc. The winding shaft unit 13 for a side disc shading strip and the winding shaft unit 25 for a triangular disc shading strip are known products, so their construction will not be described further here.
[0016] As in Fig. 3 and Fig. As shown in Figure 4, a receiving profile 14 is arranged between the end sections of the two vertical guide rails 12, in which the winding shaft unit 13 for a side window shading strip is mounted. The side window shading strip 10 and its side plate 11 can be extended and retracted through the opening at the upper end of the receiving profile 14. Preferably, a profile cover 15 is rotatably mounted on the upper side of the receiving profile 14 and is connected to the receiving profile 14 by means of one or more torsion springs. Furthermore, the two ends of the profile cover 15 are each connected to an opening and closing mechanism 16 for the profile cover, which can be moved up and down by the side plate 11. Thus, the profile cover 15 is opened before the side window shading strip 10 is moved upwards out of the receiving profile 14.The profile cover 15 will then close automatically when the side window shading strip 10 is retracted into the receiving profile 14. Currently, there are already various feasible versions with which the opening and closing mechanism 16 for the profile cover can open and close the profile cover 15 and the receiving profile 14. The opening and closing mechanism 16 for the profile cover is not a required technical component of the drive mechanism according to the invention, so the design and function of the opening and closing mechanism 16 will not be explained further here.
[0017] In the Fig. 1 and Fig. In the preferred embodiment shown in Figure 2, the integrated electric drive mechanism 3 according to the invention comprises a motion guide 30, a drive assembly 40 and a clutch transmission assembly 50.
[0018] As in Fig. 1 and Fig. As shown in Figure 2, the motion guide 30 is arranged transversely between the lower ends of the two vertical guide rails 12 and corresponds to the end part of the transverse guide rail 24 to which the motion guide 30 abuts. The motion guide 30 has a shading track movement path L that coincides with the extension path of the side window shading track 10. Due to the design, in that the extension path of the triangular window shading track 20 is shorter than the extension path of the side window shading track 10, a difference arises between the extension paths. Therefore, the extension path provided by the transverse guide rail 24 for the triangular window shading track 20 is shorter than the shading track movement path L of the motion guide 30.According to the structure of the coupling gear assembly 50, the end of the shading track movement path L facing away from the transverse guide rail 24 is defined as the starting point P1 of the movement path, and the other end of the shading track movement path L facing the transverse guide rail 24 is defined as the endpoint P2 of the movement path, with a coupling switching point P3 being located between the starting point P1 and the endpoint P2 of the movement path. The section between the coupling switching point P3 and the endpoint P2 of the movement path is defined as the coupling section L1, the length of which corresponds to the travel length of the carriage 23 in the transverse guide rail 24. The motion guide 30 can be implemented as a single component. As in . Fig. As shown in Figures 2 and 3, the movement guide 30 can alternatively be additionally mounted on one side of the receiving profile 14 in a vehicle door with the receiving profile 14 or be formed on one side of the receiving profile 14.
[0019] As in Fig. 1, Fig, 2, Fig. 6 and Fig. As shown in Figure 7, the drive assembly 40 comprises an electric motor 41, a first cable pull 42, and a second cable pull 43, wherein the first and second cables 42, 43 can be driven by the electric motor 41 in forward and reverse directions. The first and second cables 42, 43 are tensioned and connected to the two ends of the side plate 11, which projects into the two vertical guide rails 12. Via the first and second cables 42, 43, the electric motor 41 moves the two ends of the side plate 11 synchronously downward and upward in the two vertical guide rails 12 in order to extend the side window shading track 10 upward and retract it downward. In the preferred embodiment, the spindle of the electric motor 41 is connected coaxially to a first rope drum 44 and a second rope drum 45, wherein the first rope pull 42 is connected to the first rope drum 44 and the second rope pull 43 is connected to the second rope drum 45.In the preferred embodiment, the first cable pull 42 is arranged in the vertical guide rail 12 facing away from the triangular disc shading track 20, with the end of the first cable pull 42 connected to the side plate 11 of the side disc shading track 10 being guided by the movement guide 30. The second cable pull 43 is arranged in the vertical guide rail 12 facing the triangular disc shading track 20 and is connected to the other end of the side plate 11 of the side disc shading track 10. As in . Fig. 6 and Fig. As shown in Figure 7, the first and second cable pulls 42, 43 can also be maintained in a tensioned state by means of a tension regulator 46.
[0020] As in Fig. 2, Fig. 5 and Fig. As shown in Figure 6, the clutch assembly 50 comprises a clutch element 51 and a coupling element 52, which can be coupled to and uncoupled from the coupling element 52 by actuation. The clutch element 51 can be caused by the first cable pull 42 to move forwards and backwards along the shading track path L of the motion guide 30. The coupling element 52 can move within the coupling section L1 of the motion guide 30 and the transverse guide rail 24, causing the carriage 23 located in the transverse guide rail 24 to move. The clutch element 51, moving in the forward direction, can engage the coupling element 52 at the coupling switching point P3 along the shading track path L and move in the coupled state.The reverse-moving clutch transmission element 51 can detach and decouple from the coupling element 52 at the clutch switching point P3 on the shading track movement path L.
[0021] As in Fig. As shown in Figure 2, the forward movement of the clutch transmission element 51 is understood to be a movement from the starting point P1 to the endpoint P2 of the shading track's path of movement L, whereby the side window shading track 10 is extended upwards during the forward movement. Conversely, the reverse movement of the clutch transmission element 51 is understood to be a movement from the endpoint P2 to the starting point P1 of the shading track's path of movement L, whereby the side window shading track 10 is retracted downwards during the reverse movement.
[0022] Furthermore, in the process by which the forward-moving clutch transmission element 51 is moved by the first cable 42 from the starting point P1 to the endpoint P2 of the shading track's movement path L, the side plate 11 of the side window shading track 10 is simultaneously extended upwards. When the clutch transmission element 51 reaches the clutch switching point P3 in the forward direction, it can connect to the coupling element 52 and move in the coupled state, so that the triangular window shading track 20 and the side window shading track 10 are extended in a coupled manner until the clutch transmission element 51 reaches the endpoint P2 of the coupling section L1. At the same time, the side window shading track 10 and the triangular window shading track 20 are fully extended.
[0023] In the process by which the reverse-moving clutch gear element 51 is moved by the first cable pull 42 from the endpoint P2 to the starting point P1 of the shading track's movement path L, the reverse-moving clutch gear element 51 can engage with the coupling element 52 between the endpoint P2 and the clutch switching point P3 of the shading track's movement path L and move in the coupled state so that the triangular disc shading track 20 and the side disc shading track 10 are retracted in a coupled manner. When the clutch gear element 51 reaches the clutch switching point P3 on the shading track's movement path L, it will detach from the coupling element 52 and decouple.Now the triangular disc shading track 20 is completely retracted, and the first cable pull 42 brings the clutch gear element 51 further back to the starting point P1, whereby the side disc shading track 10 is retracted further until it is completely retracted.
[0024] For the clutch structure of the clutch transmission element 51 and the coupling element 52, reference is made to Fig. 5 and Fig. 6 referred.
[0025] Due to the structural design, whereby the coupling section L1 of the shading track's movement path L is located in the movement guide 23, the coupling gear element 51 moves within the movement guide 23, and the coupling element 52 extends from the movement guide 23 to the transverse guide rail 24 and then connects to the carriage 23, the first cable 42 is controlled such that it is guided only through the movement guide 30 and not through the transverse guide rail 24. This shortens the length of the first cable 42 and minimizes the number of wraps and deflections. Therefore, in the preferred embodiment, a short component is used for the coupling gear element 51 and a long component for the coupling element 52.An elastic fastening element 511 is provided at the end of the coupling element 51 facing the coupling element 52. This fastening element has a plurality of elastic claws 5110, which are arranged in a ring shape and are radially flexible and resilient, so that the elastic fastening element 511 is radially expandable and resilient. A connecting end 521 is provided at the end of the coupling element 52 facing the coupling element 51. This connecting end can be fastened to and coupled by the elastic fastening element 511 and can be detached from the elastic fastening element 511 by actuation.Preferably, a guide ramp or an arcuate surface is formed at the end of the connecting end 521 facing the elastic fastening part 511, by means of which the elastic fastening part 511 is expanded in order to hold the connecting end 521 in such a way that a smooth and correct coupling movement of the clutch transmission element 51 and the coupling element 52 is achieved.
[0026] In the preferred embodiment, the motion guide 30 and the transverse guide rail 24 are arranged at a distance from each other. To enable smooth and frictionless movement of the coupling element 52 in the motion guide 30 and the transverse guide rail 24, and at the same time to achieve correct and frictionless coupling between the coupling gear element 51 and the coupling element 52, a guide tube 31 is arranged between the transverse guide rail 24 and the motion guide 30, into which the coupling element 52 is inserted. Preferably, the coupling element 52 is made of a flexible material, and the slide 23, which is arranged at the lower end of the rocker arm 22 of the triangular disc shading track 20, is located outside the guide tube 31 and is slidable in the transverse guide rail 24.The connecting end 521 of the coupling element 52 is located outside the guide tube 31 and is movable in the movement guide 30.
[0027] For the mounting of the integrated electric drive mechanism 3 for a side window shading strip 10 and a triangular window shading strip 20 on a motor vehicle door and its use in combination with the side window shading strip 10 attached to a side window of a vehicle door and the triangular window shading strip 20 attached to a triple window of a vehicle door, the following applies: Fig. 1 and Fig. 2 referred. In Fig. 1 and Fig. In the second section, the triangular disc shading strip 20 and the side disc shading strip 10 are both retracted. The triangular disc shading strip 20 is under the influence of the winding force of the winding shaft unit 25, and the side strip 21 of the triangular disc shading strip 20 is located near the winding shaft unit 25. At the same time, the slide 23, connected to the lower end of the rocker arm 22 of the side strip 21, is located near the guide tube 31. The coupling element 52, connected to the slide 23, extends from the transverse guide rail 24 through the guide tube 31 and finally projects into the movement guide 30. The connecting end 521 of the coupling element 52 is located at the coupling switching point P3 of the shading track movement path L, and the coupling gear element 51 connected to the first cable pull 42 is located at the starting point P1 of the shading track movement path L.
[0028] To extend the side window shading strip 10 and the triangular window shading strip 20, as shown in Fig. 8 to Fig. As shown in Figure 10, the electric motor 41 of the drive assembly 40 is switched on to synchronously drive the first and second cables 42, 43 such that the first and second cables 42, 43 move the side plate 11 of the side window shading track 10 upwards in the two vertical guide rails 12 in a forward direction. This unfolds the side window shading track 10 upwards. During the process in which the side window shading track 10 is driven and then extended upwards, the first cable 42 simultaneously pulls the clutch gear element 51 in a forward direction such that the clutch gear element 51 moves from the starting point P1 to the end point P2 of the shading track's travel path L.When the clutch transmission element 51 reaches the clutch switching point P3 in the forward direction, it attaches the connecting end 521 of the coupling element 52 with the elastic fastening part 511, so that the clutch transmission element 51 engages with the coupling element 52 and moves in the coupled state. Because the first cable pull 52 causes the clutch transmission element 51 to move forward in the movement guide 30, and because the lower end of the rocker arm 22 of the side strip 21 of the triangular disc shading track 20 is moved by the coupling element 52 in the transverse guide rail 24, the triangular disc shading track 20 is extended transversely until the clutch transmission element 51 reaches the end point P2 of the coupling section L1. At the same time, the side window shading strip 10 and the triangular window shading strip 20 are fully extended.This means that the clutch transmission element 51 first connects with the coupling element 52 and then, in the coupling section L1 between the clutch switching point P3 and the end point P2 of the motion guide 30, extends the side window shading track 10 and the triangular window shading track 20 in the coupled state.
[0029] For installing the side window shading strip 10 and the triangular window shading strip 20, as shown in Fig. 9 and Fig.As shown in Figure 2, the electric motor 41 of the drive assembly 40 is switched on to synchronously drive the first and second cable pulls 42, 43 such that, in a reverse direction, they cause the side plate 11 of the side window shading track 10 to move downwards in the two vertical guide rails 12. Simultaneously, the side window shading track 10 is automatically wound up by the winding shaft unit 13 and retracted. During this process, in which the side window shading track 10 is driven and thus moved downwards and retracted, the first cable pull 42 in a reverse direction pulls the clutch gear element 51 such that the clutch gear element 51 moves from the end point P2 to the starting point P1 of the shading track's movement path L of the motion guide 30.Simultaneously, the clutch transmission element 51 connects to the coupling element 52, thus coupling the clutch transmission element 51 and the coupling element 52 together. Additionally, the winding shaft unit 25 exerts a force for automatic winding onto the triangular disc shading strip 20, causing the triangular disc shading strip 20 to retract. When the clutch transmission element 51 reaches the clutch switching point P3 in the reverse direction, the elastic fastening part 511 of the clutch transmission element 51 and the connecting end 521 of the coupling element 52 will naturally separate and decouple from each other. This is because the first cable pull 42 causes the clutch transmission element 51 to move backward, and resistance is created during the automatic winding of the triangular disc shading strip 20 by the winding shaft unit 25. The triangular disc shading strip 20 is now completely retracted.The first cable pull 42 then moves the clutch transmission element 51 backwards in the movement guide 30. The first and second cables 42, 43 synchronously retract the side window shading track 10 until the clutch transmission element 51 reaches the starting point P1 of the coupling section L1 and returns to its initial position. The side window shading track 10 is then completely retracted.
[0030] Although the present invention has been described in detail with reference to one embodiment, it is obvious to those skilled in the art that the invention is not limited to this embodiment, but rather that modifications are possible such that individual features can be omitted or different combinations of features can be implemented without exceeding the scope of protection of the appended claims.
