Description

Technical Field

[0001] This invention relates to a roller blind device and a vehicle roof. Background Technology

[0002] In some motor vehicles, the roof opening is integrated into the vehicle roof and has a sliding roof system or a fixed glass element to allow, for example, a clear view of the outside. In the case of a sliding roof system, a cover that can slide and / or rise is provided to allow not only clear visibility but also air exchange if needed. To reduce light incidence through such a glass cover when necessary, some motor vehicles have a sliding canopy system or a roller blind device. For example, document DE10146284A1 describes an open vehicle roof. Here, providing compact and reliable functionality for the interacting components of the sunshade system remains a challenge.

[0003] A consistent trend in modern automobiles is to increase the size of the roof opening to allow for larger roof glass elements, thereby enhancing visibility. To achieve this, the roof opening and the corresponding glass must accommodate the complex curvature and shape of the roof, especially in the edge areas. This is particularly true for sunshade systems, especially roller blinds used on the roofs of such vehicles, which must also be adapted to complex shapes to allow for maximum visibility. Summary of the Invention

[0004] The objective of this invention is to propose a concept for a roller blind device that helps to achieve particularly good visibility from the inside through the top without sacrificing functionality and reliability.

[0005] A roller blind device for the roof of a motor vehicle is disclosed. The roller blind device has a fixed glass element. It also has two opposing guide rails extending longitudinally, each of which is curved so that the distance between the rails varies longitudinally. Furthermore, the roller blind device has a roller blind net that is laterally and movably guided longitudinally within the guide rails. The guide rails have receiving channels for receiving a portion of the roller blind net. An insert element is arranged on the fixed glass element and extends along the receiving channel. The roller blind net is guided between the receiving channel and the insert element. The insert element has a longitudinally varying extension, thereby allowing more or less roller blind net to be received into the receiving channel.

[0006] According to the invention, a guide rail having a receiving channel is provided on at least one side of a fixed glass element, in which an insert element of the fixed glass element is arranged. The extension of the insert element varies in the longitudinal direction, thereby causing more or less of the roller shutter mesh guided in the transverse direction between the receiving channel and the insert element to be received into the receiving channel. The transverse direction refers to the direction transverse to the longitudinal direction, i.e., between the two guide rails. In other words, if the extension of the insert element in the longitudinal direction is greater at one position than at another, then the roller shutter mesh must cover a greater distance between the insert element and the receiving channel. In other words, depending on the position, the insert element forces more or less of the roller shutter mesh into the receiving channel.

[0007] This allows for precise monitoring of the longitudinal extension of the roller blind mesh between the guide rails (the area of ​​the roller blind mesh between opposing guide rails, visible to passengers). In particular, it can affect the lateral tension of the roller blind mesh along the guide rails (the tension of the roller blind mesh between the two guide rails, i.e., laterally to the longitudinal direction). For guide rails where the spacing between them varies in the longitudinal direction, the varying distance can be taken into account. Therefore, in areas where the two guide rails are arranged close together, the longitudinal extension of the insert element is chosen to be sufficiently large to receive more roller blind mesh in the receiving channel of that area. Secondly, in areas where the distance between the two guide rails is relatively large, the extension of the insert element is chosen to be relatively small. In this way, a predetermined lateral tension of the roller blind mesh can be ensured along the entire length of the guide rails in the longitudinal direction.

[0008] Therefore, the solution according to the invention can easily compensate for the different distances between the guide rails along their lengths and ensure that the roller blind mesh has sufficient lateral tension and reliable function. In other words, the "excess roller blind mesh" can be compensated for, where the tension of the fabric is preserved. In other words, the fabric width of the roller blind mesh is compensated for through the cooperation of the receiving channel and the insertion element. Therefore, there is no need to provide a special roller blind shape for the special arrangement of the guide rails, but a relatively simple rectangular shape can be used.

[0009] This invention particularly allows the guide rails to adapt very precisely to the orientation of the top profile and / or the outer edge of the top. Therefore, due to the parallel-extending guide rails, the viewing area of ​​the fixed glass element is no longer necessarily rectangular, but can be curved at the edges, thus providing maximum visibility. This also contributes to a better aesthetic appearance. Side-guided roller blinds can be retained.

[0010] This special design, including the insertion element and the receiving channel, allows the insertion element to engage within the receiving channel, helping to minimize the installation space required in the rail area.

[0011] In particular, the guide rail system requires minimal installation space in the Y and Z directions. This avoids interference with other vehicle components, such as airbags. A clear view extends to the glass edge of the fixed glass element. This also helps reduce costs; for example, relatively simple guide rail designs can be provided, especially those that can be foam-molded onto the glass cover. Fabric width compensation through the insert element and receiving channel constitutes a particularly simple structural design. For example, the insert element can also be foam-molded onto the fixed glass element.

[0012] In addition, double-glazed systems can be used for fixed glass elements, in which the roller blind system or roller blind assembly is enclosed between two panes of glass. Such systems are less susceptible to environmental influences. These systems allow for simple installation; for example, the roller blind assembly, including the roller blind shaft with drive elements, is pre-installed in the frame components and assembled together with the roller blind mesh and the two panes of glass.

[0013] The longitudinal direction can also be referred to as the vehicle's longitudinal direction or the unfolding direction of the roller shutter.

[0014] The distance between two guide rails is, for example, the net distance, or the spacing between the guide channels of the roller shutter mesh.

[0015] Fixed glass elements are, for example, transparent elements that are fixedly integrated into the vehicle roof. Fixed glass elements are designed not to move relative to the roof. In particular, this is what is known as a panoramic vehicle roof.

[0016] For example, the receiving channel opens towards the glass at the top. In other words, in a specific installation configuration of the roller blind, viewed from inside the vehicle, the receiving channel opens towards the glass at the top, while the insert element extends downwards from the fixed glass element. The receiving channel and the corresponding insert element extend longitudinally along the entire length of the guide rail, or at least most of its length. Thus, the receiving channel follows the curvature of the guide rail. In other words, the insert element is a strip-shaped element that is formed accordingly to the receiving channel.

[0017] In this context and below, insertion elements and receiving channels are provided on corresponding guide rails on one side of the fixed glass element, and similarly, they can be provided on the other side of the fixed glass element. In particular, it is preferable that each side of the fixed glass element has an insertion element for a corresponding guide rail, wherein the corresponding guide rail has a corresponding receiving channel. In this way, the width of the roller shutter mesh is compensated for on both sides as described above, and lateral tension is guaranteed.

[0018] To guide the roller shutter mesh, each guide rail has a guiding structure, such as a guide rail channel, in which the roller shutter mesh is movably guided. Specifically, the roller shutter mesh has a guiding element for each guide rail. The guiding element is, for example, a planar element arranged in the side area of ​​the roller shutter mesh for sliding displacement within the corresponding guiding structure of the guide rail, such as the guide rail channel. The guiding element is a lateral reinforcing element. For example, the guiding element is flat and flexible so that it can be wound onto a roller for winding the roller shutter mesh. The guide extends longitudinally in the corresponding side area. For example, the guiding element is a guide strip or edge strip. The corresponding guide rail channel for laterally guiding the roller shutter mesh can also be described as a lateral guiding structure. The individual guiding elements are guided by form-fitting to allow slidable movement within the guiding structure. For example, the shape and size of the guiding structure and the dimensions of the corresponding guiding elements of the roller shutter mesh are designed so that the guiding elements cannot easily slide out of the guiding structure.

[0019] According to one embodiment, the width of the insert element in the receiving channel is varied. By changing the width and thickness of the insert element in the receiving channel, more or less roller shutter mesh is guided around the insert element and received into the receiving channel. This helps to receive more or less roller shutter mesh laterally according to the spacing of the aforementioned guide rails and ensures that the roller shutter mesh has reliable lateral tension.

[0020] According to one embodiment, the extension of the insert element varies, causing the insert element to engage with the receiving channel by different amounts along corresponding guides. Depending on the degree to which the insert element protrudes into the receiving channel, more or less roller shutter mesh is received into the receiving channel. In other words, this is the so-called tongue and groove principle. The insert element guiding the roller shutter mesh presses more or less of the roller shutter mesh into the receiving channel according to its extension, thus guiding more or less roller shutter mesh between the receiving channel and the insert element in the lateral direction. The insert element, acting as a "blade," extends downward from the fixed glass element and has different lengths in the Z direction. This contributes to achieving the aforementioned advantages and functions.

[0021] According to one embodiment, the guide rails are configured and / or arranged such that they extend non-parallel to each other. For example, the guide rails extend obliquely to each other or have one or more bends during their extension. Therefore, as described above, the distance between the guide rails will vary.

[0022] According to one embodiment, the insert element is connected to a fixed glass element via a foam-molded structure. In other words, the insert element is foam-molded onto the fixed glass element.

[0023] According to one embodiment, the guide rail, together with the insertion element, is connected to a fixed glass element via a foam-molded structure. In other words, the guide rail, along with the insertion element, is molded onto the fixed glass element using a foam molding process.

[0024] For example, foam molding of inserts, rails, or both can significantly reduce costs. In particular, there is no need for complex mounting methods for rails and inserts. Furthermore, these two components can be directly attached to the fixed glass element via a foam molding process.

[0025] According to one embodiment, the roller shutter mesh has a rectangular shape. This provides the advantages and functions described above.

[0026] According to one embodiment, the roller blind device has a tension bow with a strip-shaped tension bow body fixedly connected to the roller blind mesh and extending between guide rails. The tension bow body has a guide element at one longitudinal end, by which the tension bow is movably guided in the longitudinal direction (particularly on the respective guide rail). The guide element is arranged on the tension bow body to allow movement in the lateral direction between the guide rails. In this exemplary embodiment, the tension bow body may have corresponding guide elements on both sides.

[0027] This creates a tension bow that can move relative to the guide element in the lateral direction. Therefore, the tension bow is movable in the lateral direction to compensate for different spacing of the guide rails in the longitudinal direction. The tension bow body moves relative to the guide element depending on the amount of roller shutter mesh received laterally in the receiving channel.

[0028] According to one embodiment, the guide element of the tension bow is movably guided in a corresponding guide rail and coupled to a driver. For example, the guide element is coupled in the guide rail to a pressure-resistant drive cable to drive the tension bow and deploy or retract the roller shutter. Like the roller shutter, the guide element is guided outward between the insert element and the receiving channel so as to be movably guided outward relative to the lateral direction in the guide rail outside the insert element. For example, the guide element is guided around the insert element in the receiving channel. For example, the guide element is a metal strip or metal element formed to be particularly flat and guided in the receiving channel to maintain as much consistency as possible. Therefore, the guide element is a guide element directly coupled in the guide rail and movably guided.

[0029] According to another embodiment, the guide element is provided with a magnetic element that is magnetically coupled to a drive element movable within the guide rail. In this case, the guide element of the tension bow is indirectly driven by magnetic force. The advantage of this is that the guide element does not need to be guided into a corresponding guide rail channel in the receiving channel as described above. Therefore, the guide element with the magnetic element can be arranged internally, i.e., on the side facing inwards from the insert element, while the corresponding drive element for the roller shutter is arranged externally, i.e., on the other side of the insert element, and magnetically coupled to the guide element. This concept offers advantages in terms of ease of installation and installation space, especially since a receiving guide element is not needed in the receiving channel besides the roller shutter.

[0030] According to another aspect, a vehicle roof for a motor vehicle is described, the vehicle roof having a roller shutter device according to one of the above embodiments, wherein the roller shutter device is fixedly connected to the vehicle roof. In particular, the roller shutter device having fixed glass elements is installed in a top opening of the vehicle roof. The vehicle roof can essentially achieve the advantages and functions described above. The above-described features, embodiments, and similar items can be applied accordingly.

[0031] Other advantages, features, and improvements arise from the following exemplary embodiments, which will be explained in conjunction with the accompanying drawings. In all the drawings, elements of the same design or function are identified by the same reference numerals.

[0038] Figure 7 and Figure 8 A schematic cross-sectional view of a roller blind device according to another exemplary embodiment of the present invention is shown in two different longitudinal positions. Detailed Implementation

[0039] Figure 1 A vehicle 1, specifically a motor vehicle, is shown. Vehicle 1 has a vehicle roof 2. The vehicle roof has a roof opening 3, which is closed by a fixed glass element 4. This fixed glass element is a transparent panoramic roof. The vehicle roof 2 has a roller blind device 5, which is fixedly connected to the vehicle roof 2 or the vehicle 1. The roller blind device 5 has a roller assembly 6, which includes a roller 7 on which the roller blind net 8 is wound (in...) Figure 1 (Shown schematically). The roller blind assembly 5 has two opposing guide rails 9, which are respectively arranged on both sides of the fixed glass element 4. The roller blind net 8 is laterally and movably guided in the guide rails 9. The roller assembly 6 is configured such that the roller blind net 8 can be wound onto and unwound from the roller. The guide rails 9 extend in the longitudinal direction 10. The roller blind net is rolled up and unwound in the longitudinal direction 10. The longitudinal direction can also be described as the unwinding direction of the roller blind net 8.

[0040] Here and below, from Figure 1 From the coordinate system indicated by the markings, the unfolding direction 10 extends in the X direction, thus extending in the longitudinal direction of the vehicle. The lateral direction corresponds to the Y direction. Therefore, the roller shutter 8 extends in the XY plane. The height direction corresponds to the Z direction.

[0041] Figure 2 A schematic plan view of the roller blind assembly 5 is shown. For clarity, the roller assembly 6, comprising a roller spool 7, a roller blind net 8, and guide rails 9, is shown schematically in the figure. Herein and below, as... Figure 2 and Figure 1 As shown, the guide rails 9 are arranged or extend in a non-parallel manner. In other words, the guide rails are curved in at least two dimensions and along the outer contour of the top outer contour 11 or the outer contour of the fixed glass element 4, particularly along the edges of these outer contours (see...). Figure 1 The roller shutter mesh 8 has a rectangular cross-section.

[0042] In the opposite side regions 12, the roller shutter 8 has lateral guide elements 13, which are configured as lateral guide strips. The guide elements 13 extend in the X direction and are movably guided in corresponding guide rails 9.

[0043] The roller blind device 5 is configured such that the roller blind net 8 can be wound onto or unwound from the roller shaft 7. The roller blind net 8 is movably guided along the guide rails 9 by guide elements 13 in corresponding guide rails. The roller blind net 8 extends between the guide rails 9, wherein the amount by which the roller blind net extends along the entire length of the guide rails 9 varies depending on the unfolded state relative to the X direction (longitudinal direction 10). The roller blind net 8 is under a predetermined tension in the transverse direction (Y direction), which will be described in detail below.

[0044] The following description will focus on one side of the roller blind assembly 5, which includes the fixed glass element 4, with reference to several exemplary embodiments. It should be noted that the other side, i.e., the opposite guide rail 9, is also correspondingly configured. Therefore, the following description also applies to the other side.

[0045] observe Figure 2 It is evident that, due to the non-parallel guide rails 9, there are different distances between the guide rails 9 at different positions along the longitudinal direction 10 (X direction). At position A, the first distance 14 is greater than the second distance 15 at position B, where position A is located at the upper end of the guide rails 9, and position B is approximately in the middle. Therefore, the first outward extension X of the roller shutter mesh 8 in the side region 12 is... A Less than the second extension X at position B B Although the guide rail 9 is in a non-parallel state, the roller blind 8 can be fully tensioned in a predetermined manner along the entire length of the guide rail 9 in the lateral direction, and can be rolled up and unrolled without any problems. An exemplary embodiment of the roller blind device with fixed glass element 4 will be described below, which allows for compensation of the exemplary overhang.

[0046] Figure 3 A schematic cross-sectional view of a roller blind device 5 according to a first exemplary embodiment is shown. (Refer to...) Figure 2 The described features also apply. For example, according to Figure 2 This cross-sectional view is taken at position B of the left guide rail 9. It shows a portion of the roller blind assembly 5 with a fixed glass element 4. The guide rail 9 is foamed onto the bottom side of the fixed glass element 4 via a foaming structure 16. For example, the foaming structure is a PU (polyurethane) foaming structure. The guide rail 9 has a guide structure 17 in the form of a guide channel for the roller blind mesh 8. The guide rail 9 also has a drive channel 18 in which a pressure-resistant drive cable is movably guided, and this drive cable is coupled to a motor (not shown) for driving. By means of the drive cable 18 and through its coupling with the roller blind mesh 8, the roller blind mesh can be moved in the X direction.

[0047] Furthermore, the insert element 19 is foam-molded on the bottom side of the fixed glass element 4. It is fixedly connected to the fixed glass element 4 by the same foam-molded structure 16 as the guide rail 9. The insert element 19 is formed as a protrusion extending downward in the Z direction, such as a "blade". The insert element 19 engages with the receiving channel 20 of the guide rail 9. The receiving channel 20 is located further inside the guide rail 9 relative to the guide structure 17 or drive channel 18. The roller shutter 8 is guided between the receiving channel 20 and the insert element 19. The roller shutter 8 extends outward along the receiving channel 20, particularly in the transverse direction, starting from the middle and ending in the guide structure 17. In the Z direction (height direction), the insert element 19 has an extension 21 (see double arrow), which can also be described as the length of the insert element 19. The insert element 19 extends along the guide rail 9 along the receiving channel 20.

[0048] The extension 21 varies in the longitudinal direction 10. In this exemplary embodiment, the insertion element 19 is in Figure 3 The maximum extension 21 is observed at position B, while the minimum extension 21 is observed at position A. Depending on the extension 21 of the inserted element, the roller shutter mesh 8 must cover a greater or smaller distance within the receiving channel 20 of the guide rail 9. Therefore, the aforementioned lateral tension of the roller shutter mesh in the Y direction can be ensured at each position along the guide rail. Figure 2 At position B, the roller shutter mesh is essentially matched to the receiving channel 20 along its entire circumference, while at position A, for example, significantly less roller shutter mesh is received in the receiving channel 20.

[0049] Figure 3 The exemplary embodiments described above can achieve the advantages and functions described above.

[0050] Figure 4 Another exemplary embodiment of the invention is shown, which is essentially the same as... Figure 3 Consistent with the exemplary embodiments herein, wherein reference is again applied. Figure 2 The basic principle described above differs in that the fixed glass element 4 consists of two pieces of glass 4a and 4b, between which the roller shutter mesh 8 is guided. The statements above regarding compensation for variations in the spacing between the guide rails 9 also apply accordingly.

[0051] The double-glazed structure allows for the creation of an insulated glass system. Here, a roller shutter 8 is enclosed between two panes of glass 4a and 4b. Enclosures, such as seals or airtight seals, are provided on the sides and front, for example, in the form of frames or sealing elements. At the rear, for example, a removable frame section houses the roller shutter mechanism 5, specifically the roller 7 and the drive system. The double-glazed system can be completely closed via the movable frame section. Optionally, a sealing system or membrane can be provided to ensure pressure equalization.

[0052] Figure 5 and Figure 6 It shows the relationship with Figure 3 Similarly, in another exemplary embodiment of the present invention, wherein Figure 5 A cross-sectional view of the corresponding roller shutter device 5 at position A is shown, while Figure 6 A cross-sectional view of the roller shutter device 5 at position B is shown. Figure 3 The relevant instructions are also largely applicable. Figure 5 and Figure 6 In this configuration, the guide rail 9 and the insertion element 19 are connected to the fixed glass element 4 via a foam-molded structure 16. The guide rail 9 has a receiving channel 20.

[0053] according to Figure 5 The insert element 19 has only a slight extension 21, so that the roller shutter 8 extends substantially directly into the guide structure 17 in the lateral direction between the insert element 19 and the receiving channel 20. Therefore, very little or no (equivalent to very little) of the roller shutter 8 is received into the receiving channel 20. However, according to... Figure 6 At position B, the insertion element 19 has the maximum extension 21, so more of the roller shutter mesh 8 is received into the receiving channel 20.

[0054] according to Figure 5 and Figure 6 The roller blind assembly 5 has a tension bow 22. The tension bow 22 extends laterally at the front end 25 of the roller blind mesh 8 (see...). Figure 2 The tension bow 22 has a strip-shaped tension bow body 23, which is fixedly connected to the roller shutter mesh 8 and extends between guide rails 9. The tension bow body 23 has a guide element 24 at its longitudinal end 26 facing the guide rails 9, by which the tension bow 22 is movably guided in the longitudinal direction within the guide rails 9, or guided in a guide structure 17 or a similar guide structure. For this purpose, the outer end of the guide element 24 may optionally have a slider 27. The guide element 24 is, for example, a metal element, such as a metal strip or steel strip. The guide element 24 or the slider 27 may be coupled to a driver for longitudinal movement of the tension bow 22 (not shown).

[0055] The guide element 24 is arranged on the tension bow body 23 so as to move laterally between the guide rails 9. This is in Figure 5 and Figure 6 As shown in the diagram, it is clear that the tension bow body 23 has moved along the guide element 24, getting closer to ( Figure 6 or further away ( Figure 5 Insert element 19. Thus, the aforementioned advantages and functions are realized.

[0056] exist Figure 5 and Figure 6In the example, the guide element 24 of the tension bow 22 is guided in the guide rail 9 outside the insertion element 19. For example, here it is guided around the insertion element 19 so as to match the inner wall of the receiving channel 20 and not to interfere with the compensation of the fabric width by the roller blind 8.

[0057] Figure 7 and Figure 8 Another exemplary embodiment is shown, which is substantially the same as the reference. Figure 5 and Figure 6 The examples described are consistent. The difference lies in the structure of the tension bow 22. The guide element 24 is not directly movably guided in the corresponding guide rail 9, but instead includes a magnetic element 28 and terminates inside the insertion element 19, or optionally, as shown in the exemplary embodiment, is movably guided in the insertion element 19. For this purpose, the insertion element 19 has an opening 29 on its side that opens towards the center. Corresponding to the magnetic element 28, a drive element 30 is provided, which is movably guided in the drive channel 18. The drive element 30 is fixedly connected to the roller blind 8, for example, in the area of ​​the guide element 13 at the front end 26. The drive element 30 has a corresponding magnetic element 31 and is magnetically coupled to the magnetic element 28 of the tension bow 22. The drive element 30 is connected to a driver, such as an electric motor, via a pressure-resistant drive cable (not shown). The tension bow 22 is also moved by the movement of the drive element 30, thereby rolling the roller blind 8 onto or off the roller 7 and moving it along the guide rail 9 to cover or expose the fixed glass element 4.
