Description

Technical Field

[0001] The invention relates to a shading device for a motor vehicle, in particular an automobile, and a motor vehicle section of a motor vehicle, in particular a motor vehicle roof or a window area of ​​a motor vehicle, which is equipped with the shading device. Background Art

[0002] Window covering systems, such as roller blind systems, for motor vehicles are generally known from the prior art.

[0003] The known device is installed in a motor vehicle and allows a textile shade sheet to be extended and retracted. In the extended state, the textile shade sheet partially or completely covers the panoramic roof or the windows and shades the interior of the motor vehicle. This protects people in the motor vehicle from excessive light penetration and glare; in addition, the heating effects caused by the light penetration can be counteracted accordingly.

[0004] Recently, there has been a trend to install light systems in the interior of motor vehicles in order to create a dynamic and modern driving experience. For example, such light systems include illuminated light strips or glass roof elements into which light is coupled.

[0005] Attempts have been made in the prior art to integrate light devices into shading devices. These attempts involved integrating light guides or similar elements into the shading textile web. However, these attempts were unsuccessful because the light guides break when the shading textile web is retracted and extended, and the shading devices therefore do not meet the service life requirements required for automotive applications. Summary of the Invention

[0006] Against this background, the object of the present invention is to provide a shading device with light-emitting properties that is particularly easy to implement and allows for sufficiently fail-safe use. The object of the present invention is at least to provide an alternative to the prior art shading devices.

[0007] This object(s) is achieved by a screening device according to claim 1. Preferred embodiments are the subject matter of the dependent claims.

[0008] The shielding device according to the invention for a motor vehicle has, in particular:

[0009] an assembly section, via which the screening device is assembled in accordance with regulations on a motor vehicle section of a motor vehicle; and

[0010] A textile web which, after the screening device has been installed as specified, is held and can be adjusted so that it can at least partially cover a window of a motor vehicle for screening the interior of the motor vehicle; wherein

[0011] The textile web comprises at least one carrier textile web which is provided with a light-emitting layer element such that the light-emitting layer element can emit light into the interior of the motor vehicle, in particular when activated.

[0012] In particular, the mounting section is designed such that the screening device can be fastened to a vehicle section. For example, the vehicle section is a body section or a trim section in the interior of the vehicle, which is spatially arranged such that after mounting, the screening device is located near a window of the vehicle. For example, the window is a panoramic roof, a side window, a rear window, or a front window of the vehicle.

[0013] The textile web can be held in a continuously stretched manner, for example in a frame, wherein the frame can be adjusted along the window.

[0014] Alternatively, the textile web can be flexible so that it can be adjusted into a state covering the window by being unfolded or spread out and can then be rolled up or folded up again from this state in order to return to its original state.

[0015] In particular, the carrier textile web is a thin, flat plastic textile web that can be perforated so that it is slightly light-transmissive when covering the window and allows a see-through view into the interior. Alternatively, the carrier textile web can be opaque or light-proof. Preferably, the carrier textile web has a thickness of 0.1 mm to 2 mm.

[0016] For example, the plastic textile web that forms the carrier textile web can be formed by polyester and / or polyurethane.In addition, the plastic textile web itself can have a layer structure and can be composed of a plurality of individual textile layers that are connected to each other in a planar manner.

[0017] For example, the carrier textile web as a whole or individual textile layers of the textile layers are knitted or woven or particularly preferably woven, each preferably formed from plastic filaments.

[0018] Preferably, the light-emitting layer element is a flexible layer element having a thickness in the order of magnitude of the thickness of the carrier textile web. Preferably, the light-emitting layer element is materially connected to the carrier textile web, for example, laminated, glued or fastened to the carrier textile web by means of an adhesive.

[0019] For example, the light-emitting layer element is a flexible printed circuit board composed of a polymer carrier having a circuit structure formed thereon, wherein LEDs are arranged at desired locations and emit light into the interior when activated.

[0020] Alternatively and preferably, the light-emitting layer element is a light-emitting foil as will be explained below, in particular an electrically controllable, electroluminescent luminescent foil.

[0021] The light-emitting layer element can be arranged in such a way that it emits or irradiates light indirectly or directly into the interior.

[0022] In the case of indirect illumination, the layer element is preferably arranged in such a way that it emits light into the space between the window and the carrier textile web, where it is reflected in the direction of the interior.

[0023] For the preferred direct illumination, however, the light-emitting layer element is preferably arranged in such a way that the emitted light radiates into the interior without prior reflection.

[0024] The combination of a carrier textile web and a light-emitting layer element, in particular a light-emitting foil, makes it possible to integrate light effects / light experiences and / or interior lighting into the shading device simply and with a low probability of failure.

[0025] Furthermore, the light-emitting foil can be easily separated from the carrier textile web after disassembly, and the screening device thus enables good reusability (recyclability) of the materials used.

[0026] The screening device according to the invention is preferably designed such that the textile web is held on the receiving section in a rollable / unrollable manner and can be adjusted by unrolling so that in the unrolled state the textile web at least partially covers the window of the motor vehicle for screening the interior of the motor vehicle;

[0027] The light-emitting layer element is the already mentioned light-emitting foil, which is applied to the carrier textile web on the side of the carrier textile web that faces away from the interior space as required, so that when the textile web is adjusted, the light-emitting foil is rolled up / unrolled together with the textile web.

[0028] For example, the receiving section contains a winding shaft, to which the textile web is fastened and which can be rotated, preferably by means of a drive unit, so that the textile web can be rolled onto or unwound from the winding shaft.

[0029] Preferably, the drive unit is an electric motor.

[0030] For example, the textile web is provided with a tensioning frame on the front edge of the carrier textile web, and the drive unit is indirectly connected to the tensioning frame, preferably via a tensioning device (e.g., a tensioning cable). When the drive unit is activated, the textile web is unwound (extended) from the winding shaft by the drive unit pulling the tensioning frame along the window so that the textile web at least partially covers the window.

[0031] The subsequent rolling up (retraction) of the textile shade web can be achieved in that a drive unit acting on the winding shaft rotates the winding shaft in the opposite direction and also retracts the tensioning frame.

[0032] Alternatively, a mechanical energy store can be provided which stores mechanical energy when the drive unit pulls the textile web along the window and releases the stored energy again during the subsequent rolling up. Preferably, the energy store is a spring unit.

[0033] The light-emitting foil, in particular an electroluminescent light-emitting foil, is in particular laminated (or glued) onto the carrier textile web and is located on the side of the carrier textile web facing away from the interior. In this respect, the light-emitting foil cannot be seen or perceived from the interior, at least in the region where it is preferably materially connected to the carrier textile web.

[0034] Particularly preferably, the light-emitting foil is structured in the same manner as the carrier textile web itself in the region where it is connected to the carrier textile web. If the carrier textile web is perforated in order—as described above—to allow a certain degree of light penetration and light transmission, the light-emitting foil is also perforated at least in the region where it overlaps and is connected to the carrier textile web in order to achieve the optical effect of the entire textile web.

[0035] The combination of a carrier textile web and a light-emitting foil makes it possible to integrate light effects and / or interior lighting into a shading device with a roll-up / unrolling system, wherein the light-emitting foil can be rolled up and unrolled very well, so that the service life of the lighting function for automotive applications is sufficiently long.

[0036] The carrier textile web of the shielding device according to the invention comprises at least one opening, and a light-emitting foil is applied to the carrier textile web such that the light-emitting foil can emit light through the opening, in particular into the interior of a motor vehicle, when the light-emitting foil is activated.

[0037] In this variant, the light-emitting foil preferably completely covers the opening, wherein, after activation of the light-emitting foil, corresponding light shines in a controlled manner through the opening directly into the interior.

[0038] Thus, to the interior, the light-emitting foil is exposed and visible.

[0039] Preferably, a mask can be arranged on the side of the light-emitting foil facing the interior in order to generate a visible light pattern.

[0040] Additionally or alternatively, the openings can be contoured such that a light pattern is generated thereby. The light pattern can be generated in particular by forming a plurality of openings in the carrier textile web, which are covered by the light-emitting foil and thus together form the light pattern.

[0041] Both variants make it possible to display icons or shapes that are perceived as light effects, for example.

[0042] The textile web is preferably configured such that the light-emitting foil covers one or more openings.

[0043] Alternatively, a respective light-emitting foil can be assigned to each of the plurality of openings, which light-emitting foils can emit light independently of one another.

[0044] It should also be emphasized that the invention—the combination of a carrier textile web and a thin, flat, light-emitting foil—makes it possible to introduce light effects into the vehicle interior with little effort.

[0045] The shading device is preferably designed such that the light-emitting foil is an expandable foil which expands when the textile web is rolled up.

[0046] The extensibility of the light-emitting foil ensures that deformations of the light-emitting foil caused by the corresponding rolling radii do not lead to damage when the textile web is rolled up and unrolled.

[0047] In terms of size, the area dimensions of the light-emitting foil can be identical to the area dimensions of the carrier textile web.

[0048] Preferably, however, the light-emitting foil is smaller than the textile web and is applied to the carrier textile web only in the region of the opening, so that it covers the opening and can emit light through the opening into the interior of the motor vehicle.

[0049] As already mentioned, a corresponding light-emitting foil can be applied to the carrier textile web for each opening, or the light-emitting foil can cover a plurality of openings.

[0050] Preferably, one or more light-emitting foils have the dimensions of DIN A2 (42×59.4 cm) or A3 (29.7×42 cm), wherein the respective light-emitting foil is structured in the same manner as the carrier textile web (e.g. perforated), in particular in the region in which it is connected to the carrier textile web, so that the edges of the light-emitting foil are as invisible as possible when the textile web is observed from an interior space.

[0051] Preferably, the shading device is designed such that the textile web comprises a further carrier textile web, which is arranged relative to the carrier textile web in such a way that the light-emitting layer element is arranged between the carrier textile web and the further carrier textile web.

[0052] This configuration ensures a more stable hold for the one or more light-emitting foils. Furthermore, the textile web has a more aesthetically pleasing appearance when viewed from outside the motor vehicle, since the edges of the one or more light-emitting foils applied to the carrier textile web are covered by the further carrier textile web.

[0053] Furthermore, a light pattern can also be displayed to the outside by forming at least one, preferably a plurality of, openings in the further carrier textile web.

[0054] Preferably, the screening device according to the present invention further comprises:

[0055] Guide sections in which the textile web is guided during rolling up / unrolling; electrical contacting of the light-emitting foil is effected via at least one of the guide sections.

[0056] For example, the guide section is a guide rail or a guide track.

[0057] The guide section is preferably designed such that when the drive unit is activated and the textile web is unwound, the aforementioned tensioning frame is guided by its side ends in the guide section in order to pull the textile web along the window. For example, the electrical contact is established on the guide section via sliding contacts or rolling contacts.

[0058] Preferably, the screening device further comprises:

[0059] a winding shaft, which forms the receiving section and holds the textile web in a manner that allows it to be rolled up / unrolled; wherein

[0060] Electrical contacting of the light-emitting foil is achieved via the winding reel.

[0061] If a plurality of light-emitting foils are applied to the carrier textile web, each of these light-emitting foils can be electrically contacted via a guide section or via a winding shaft.

[0062] Alternatively, one of the one or more light-emitting foils can be electrically contacted via the guide section and the other light-emitting foil can be electrically contacted via the winding shaft.

[0063] The circuits that conduct the current and voltage can be implemented in different ways. For example:

[0064] The electrical contacting of the screening device is effected via a cable connection which extends at least partially above / in the textile web, in particular to a guide section or to a winding shaft;

[0065] The electrical contacting of the screening device is achieved via electrically conductive threads of the carrier textile web and / or of a further carrier textile web; and / or

[0066] The electrical contacting of the screening device is achieved via an electrical coating which is applied to the carrier textile web and / or to a further carrier textile web.

[0067] For example, the electrically conductive threads may be warp threads or weft threads of a carrier textile web configured as a woven fabric.

[0068] The electrically conductive coating can be a lacquer or a printed structure.

[0069] In addition, the present invention relates to a motor vehicle section of a motor vehicle, in particular a motor vehicle roof or a window region of a motor vehicle, the motor vehicle roof / the motor vehicle window being equipped with a shading device as described above. BRIEF DESCRIPTION OF THE DRAWINGS

[0070] Hereinafter, a preferred embodiment of the present invention is described with reference to the accompanying drawings.

[0071] Figure 1 The invention shows a shading device for a motor vehicle, which essentially comprises a textile web with a carrier textile web, two light-emitting foils and a tensioning frame, wherein the textile web is fastened to a winding shaft which can be rotated by an electric drive unit for rolling up and unrolling the textile web, wherein Figure 1 a plan view from outside the motor vehicle corresponding to the stretched textile web; and

[0072] Figure 2a and Figure 2b Two variants of textile webs are shown in longitudinal section, wherein Figure 2a The variant in has a single carrier textile web, on which the corresponding light-emitting foil is applied, so that the light emitted by the light-emitting foil passes through different openings in the carrier textile web, while Figure 2bThe variant in has an additional carrier textile web which is arranged in such a way that the light-emitting foil is located between the two carrier textile webs. DETAILED DESCRIPTION

[0073] Figure 1 The shading device 1 according to the invention is shown, which is intended to be installed on a motor vehicle K in order to shade the interior of the motor vehicle K and to protect it from excessive sunlight. Figure 1 Motor vehicle K is shown from above.

[0074] The coordinate system shown is used to illustrate the installation orientation of the screening device 1. The X-axis of the coordinate system corresponds to the longitudinal axis and the direction of travel in reverse of the vehicle K. Thus, the Y-axis of the coordinate system corresponds to the width of the vehicle K, and the Z-axis corresponds to the height of the vehicle K.

[0075] The screening device 1 comprises a textile web 2, the longitudinal extension of which extends in the direction of the illustrated X axis and the transverse extension of which extends in the direction of the illustrated Y axis. The thickness direction of the textile web 2 corresponds to the Z axis.

[0076] The textile web 2 is provided with a tensioning frame 3 on its front edge in the negative X direction and is fastened to a winding shaft 4 forming a receiving section by means of its rear edge in the negative X direction. The winding shaft 4 is spring-prestressed, for example.

[0077] Figure 1 The shading device 1 shown is intended in particular for a panoramic roof PD formed from glass of a motor vehicle K, wherein the textile web 2 in the fully unfolded state shown completely covers the panoramic roof PD on the inside of the motor vehicle K and thus shades the interior.

[0078] The screening device 1 is assembled via an assembly section that is fastened to a vehicle section as required by connecting techniques (e.g., screws, rivets, and / or snaps). This vehicle section can be, for example, a part of the vehicle body or a part of the interior trim of a vehicle K.

[0079] Furthermore, the shading device 1 comprises an electric drive unit 5 which is connected on the one hand indirectly, for example via a Bowden cable, to the tensioning tent frame 3 and on the other hand is coupled to the winding shaft 4 .

[0080] The electric drive unit 5 can be controlled such that it winds up the textile web 2 onto the winding shaft 4 or unwinds it.

[0081] In the completely wound-up state on the winding shaft 4 , the textile web 2 is completely stowed and does not cover the panoramic roof PD, so that complete penetration of light into the interior of the motor vehicle K through the panoramic roof PD is possible.

[0082] If the electric drive unit 5 is now activated, it pulls the extension frame 3 along the panoramic roof PD in the positive X direction, thereby unwinding the textile web 2 from the winding shaft 4 up to a maximum of Figure 1 It is shown unfolded, and the textile web covers the panoramic roof PD.

[0083] Depending on the desired degree of shading of the interior of the motor vehicle, the drive unit 5 can stop the extension awning 3 in a desired position.

[0084] If the drive unit 5 is subsequently activated in order to retract the textile web 2 , the drive unit 5 rotates the winding shaft 4 in the opposite direction, thereby winding the textile web 2 onto the winding shaft 4 until it is finally completely retracted.

[0085] Preferably, the textile web 2 is infinitely adjustable between the two extreme states—completely extended or completely rolled up—by the drive unit 5 being stopped in the desired position of the textile web 2 so that it at least partially covers the panoramic roof.

[0086] During adjustment, the textile web 2 is held in a guided manner. For this purpose, the screening device 1 has a guide section 6 that extends in the X direction parallel to the textile web 2. For example, the guide section 6 can be a guide rail or a guide track, which preferably also serves as an assembly section.

[0087] The guide section 6 is designed such that the tensioning frame 3 is preferably supported in it by means of a guide bearing and is guided during adjustment of the textile web 2. The guide bearing is, for example, a rolling bearing or a sliding bearing.

[0088] It is essential for the invention that the textile web 2 has at least one light-emitting layer element which can be electrically controlled.

[0089] In the preferred embodiment shown, the textile web 2 contains two light-emitting layer elements, which can each be electrically controlled independently of one another.

[0090] The light-emitting layer elements shown are, in particular, electroluminescent lighting foils 70 , 71 , which can be switched on and off again by electrical actuation.

[0091] The lighting foils 70 , 71 have dimensions in the X / Y plane, for example, according to DIN A2 (42×59.4 cm) or A3 (29.7×42 cm).

[0092] When switched on, each electroluminescent lighting foil 70, 71 emits light. This light can be white or have a specific desired color tone. Lighting foils 70, 71 are preferably designed so that the color of the emitted light is variable. This variability in the color of the emitted light can also be introduced via an additional textile layer covering the lighting foil.

[0093] Figure 2a A longitudinal section through the textile web 2 in the region of the lighting foil 71 is schematically shown, wherein the illustration corresponds to a plane spanned by the X-axis and the Z-axis.

[0094] It can be seen that the textile web 2 has a carrier textile web 20, as shown in FIG. Figure 1 As is clear, the carrier textile web is provided with a tensioning frame 3 on the one hand and is fastened to a winding shaft 4 on the other hand.

[0095] The carrier textile web 20 has a plurality of openings 21 which extend through the carrier textile web 20 .

[0096] The lighting foil 71 is applied to the carrier textile web 20 , for example by lamination, and is firmly connected thereto. The lighting foil 71 is applied to the carrier textile web 20 in places such that it covers the openings 21 .

[0097] The number and contour of the openings 21 define an illuminated structure that is perceived in the interior of the motor vehicle 7 after the foil 71 has been switched on.

[0098] Preferably, a further lighting foil 70 is also applied to the carrier textile web 20 , wherein the carrier textile web preferably has a plurality of openings 21 in this region.

[0099] The two lighting foils 70 , 71 are flexible in their structure, so that they can be rolled up onto a winding shaft 4 as part of the textile web 2 together with the carrier textile web 20 and unwound from the winding shaft.

[0100] As intended, the illustrated top side of the carrier textile web 20 , to which the luminous foils 70 , 71 are applied, corresponds to the side facing away from the interior of the motor vehicle.

[0101] Preferably, the lighting foils 70, 71 are structured in the same manner as the carrier textile web 20 itself in the region where they overlap with the carrier textile web 20. If the carrier textile web 20 has perforations in this region, the lighting foils 70, 71 are preferably also perforated in this region. As a result, the fastening of the lighting foils 70, 71 is only faintly perceptible from the interior of the motor vehicle K, if at all.

[0102] Preferably, the electrical contacting of the light-emitting foils 70, 71 is achieved via cable connections 80, 81, for example ribbon cables (see Figure 1 ).

[0103] Preferably, the cable connections 80 , 81 extend on the same side of the carrier textile web 20 as the side to which the lighting foils 70 , 71 are also applied.

[0104] The cable connection 80 electrically contacts the lighting foil 70 , so that it can be actuated to be switched on and off.

[0105] The cable connection 80 extends in the X direction from the lighting foil 70 to the tensioning frame 3 fastened to the front edge of the carrier textile web 20 and from there to at least one of the guide sections.

[0106] The electrical contacting in or on the guide section can be realized, for example, by means of sliding contacts or rolling contacts.

[0107] On the contrary, the cable connection 81 electrically contacts the light foil 71 so that it can also be controlled. However, the cable connection 81 does not extend from the light foil 71 to the tent frame 3, but to the winding shaft 4 and from there, for example, in the direction of the drive unit 5.

[0108] For example, the electrical contacting at the end of the winding shaft 4 lying in the Y direction can again be realized, for example, by means of sliding contacts or rolling contacts.

[0109] Figure 2b Further variants of textile webs 2 are shown.

[0110] This additional variant is Figure 2a The variant in FIG. 1 differs in that the textile web 2 has a further carrier textile web 22 .

[0111] The further carrier textile web 22 is located on the side of the carrier textile web 20 facing away from the interior, so that the luminous foils 70, 71 are located between the carrier textile web 20 and the further carrier textile web 22. This gives the textile web 20 greater stability and a more aesthetically pleasing appearance when the textile web 2 is viewed from outside the motor vehicle K in the expanded state.

[0112] also, Figure 2b Variants in Figure 2a The variants in are constructed identically, so reference is made to the corresponding explanations.

[0113] According to the invention, light effects and light designs can be easily integrated into the shading device 1 , in particular because the connection between the one or more carrier textile webs 20 , 22 and the light foils 70 , 71 can be realized without great production complexity.

[0114] Furthermore, the probability of failure of the luminous foils 70 , 71 is low, since these luminous foils have a flexibility which allows easy winding up on and unwinding from the winding shaft 4 .

[0115] Furthermore, different light effects and light designs can be easily realized by varying the number and size of the light foils 70 , 71 and / or the number and contour of the openings 21 .

[0116] This embodiment describes a shading device for a panoramic roof, but the invention is not limited thereto. The shading device can also be used in other window areas, such as side windows, rear windows or front windows of a motor vehicle.

[0117] The explanations preceding the description of the figures also apply to this embodiment, and vice versa.
