Description

The invention relates to a fabric for a motor vehicle interior.

Motor vehicle interiors are often equipped with fabrics for shading, covering or partitioning. For example, flexible fabrics in the form of shading roller blinds for shading side windows, rear windows and glass roofs have been known for a long time.

The object of the invention is to provide a fabric of the type mentioned at the outset which offers advantages over the prior art and in particular has an expanded range of functions.

This object is achieved by a fabric with the features of claim 1.

The fabric according to the invention has an opaque and dimensionally stable support structure and a multi-layer functional layer structure supported by the support structure and extending flatly, the functional layer structure having a light-protection functional layer which can be electrically controlled between different light-transmissive states to protect the motor vehicle interior from incident light, and at least one further functional layer .

The support structure serves to support and/or stiffen the multi-layer functional layer structure. For this purpose, the support structure is dimensionally stable. The dimensional stability can be achieved by an appropriate choice of material and/or a suitable shape. The supporting structure is also transparent. For this purpose, the supporting structure can be made of a transparent material. Alternatively or additionally, the support structure can have a transparent shape. For example, the support structure can be made in the form of a frame with a frame opening.

The interior of the motor vehicle can be optionally darkened and/or shaded by the light protection functional layer. For this purpose, the light protection functional layer can be electrically controlled and/or switched between the differently light-permeable states. At least two different states are provided, for example a fully opaque state and a fully opaque state. It is also conceivable and possible that the different translucent states allow a stepwise, gradual or stepless darkening and/or shading of the motor vehicle interior. The functional light protection layer preferably has electrochromic and/or thermochromic properties.

The functional layer structure comprises in particular the light protection functional layer and the at least one further functional layer. The at least one further functional layer has at least one further function. The invention is based on the knowledge that modern motor vehicles have to meet constantly increasing user expectations. This in particular with regard to the interior of the motor vehicle and the related expectations of the user in terms of comfort, infotainment, safety and the like. The function of the further functional layer is different in different configurations and, for example, a comfort, infotainment and/or safety function. In one embodiment, said function of the at least one further functional layer can be switched and/or controlled electrically. In a further refinement, the function cannot be switched and/or controlled and, in other words, is static and/or always present. In one configuration, the functional layer structure has no light protection functional layer. In one embodiment, the functional layer structure is not inherently dimensionally stable or at least less dimensionally stable than the supporting structure. In one embodiment, the functional layer structure is flexible and/or limp by itself. In one configuration, the individual layers of the functional layer structure are each formed as a layer, layer and/or film. The individual layers of the functional layer structure each extend over a surface area and are arranged one on top of the other, in particular congruently. In one embodiment, the functional layer structure is connected to a control device which is set up to control the said functions. The control device can be assigned to the flat structure, a higher-level construction module or a motor vehicle that is intended to be equipped with the flat structure.

In an embodiment of the invention, the support structure has a pane made of a translucent material, to which the functional layer structure is applied. The pane is preferably made of glass or another dimensionally stable and translucent material. For example, the pane can be made of polycarbonate, Plexiglas or polymethyl methacrylate (PMMA). The functional layer structure is applied to the pane using a suitable process. For example, the functional layer structure can be glued onto the pane. Among other things, an adhesive bonding method can be used for this purpose, in particular hot bonding and/or chemical bonding. Alternatively or additionally, the support structure has a support frame in which the radio tion layer structure is taken all around. The support frame is made of a dimensionally stable material, preferably metal and/or plastic. The support frame preferably has a multi-part, in particular two-part, design, with the functional layer structure being held between the parts of the support frame, for example by a clamping force, and at the same time tensioned. The multi-part frame preferably has a plurality of mutually corresponding profiles or frame parts, between which the individual layers of the functional layer structure are held and stretched at the same time. As an alternative or in addition, the functional layer structure can be overmoulded and/or foamed for mounting in the support frame. This, for example, by means of an insert injection molding process and/or a foaming process, preferably with polyurethane foam.

In a further embodiment of the invention, the functional light protection layer has an electrically switchable film with electrochromic properties, in particular a PDLC film and/or an SPD film. PDLC films (Polymer Dispersed Liquid Crystal) and SPD films (Suspended Particle Device) are known as such and have proven to be particularly advantageous for the present application. The electrically switchable film changes its light-transmitting properties when an electrical voltage is applied and in this way can be electrically controlled between the different light-transmitting states mentioned. For this purpose, the electrically switchable film can be connected to the control device already mentioned and/or an on-board electrical system of the motor vehicle.

In a further embodiment of the invention, an information function layer is present and set up to display variable information. The information function layer functions at least as a display and/or projection surface. The variable information can be, for example, information from an infotainment system in the motor vehicle. For this purpose, the information function layer is preferably at least indirectly connected to the infotainment system. Alternatively or additionally, the information function layer can be set up for at least indirect coupling to a smartphone, a tablet and/or similar portable devices. In this way, information that can be called up via the aforementioned devices can be “mirrored” on the information function situation. The information that can be displayed using the information function layer can alternatively or additionally serve optical purposes, for example to create a specific ambience in the motor vehicle interior. The information that can be displayed using the information function layer can alternatively or additionally be used for lighting purposes, for example by displaying light with a corresponding brightness. In this way, the information function layer can function as an illumination function layer.

In a further embodiment of the invention, the information function layer has an LED display, preferably in the form of an OLED film. The LED display is preferably flexible and/or bendable and is designed as a film for this purpose. Particular advantages can be achieved when using an OLED film as an information function layer.

In a further embodiment of the invention, the LED display can be folded relative to the supporting structure between different positions about a folding axis. Due to the mobility in the different positions, the user can change the position of the LED display, whereby the readability of the variable information can be improved. In this embodiment of the invention, the LED display is preferably attached to a carrier and/or has such a carrier. The carrier is relatively movable, more precisely: foldable, hinged to the supporting structure. LED displays, in particular OLED films, are often only available prefabricated on the market in certain sizes at low cost, while adapted sizes are possible in principle, but are associated with increased costs. As a result of this configuration, in addition to better readability, a cost advantage can also be achieved.

In a further embodiment of the invention, an input function layer is present and set up for entering control commands. The input function layer is used for interaction with the user. The control commands that can be entered using the input function position can, for example, relate to the different functions of the fabric. Alternatively or additionally, control commands for controlling the infotainment system of the motor vehicle can be entered. In one embodiment of the invention, the input function layer is integrated into the information function layer or vice versa.

In a further embodiment of the invention, the input function layer has a touch-sensitive input surface with an inductive, capacitive and/or resistive operating principle. The input surface can also be referred to as a touch surface. The input function layer thus forms a kind of touch screen. This, for example, in combination with the information function layer and/or its LED display or OLED film.

In a further embodiment of the invention, a thermal function layer is present and set up to emit electrically generated radiant heat. The thermal function layer is used for improved comfort. To generate the radiant heat, the thermal function layer is preferably connected to the on-board electrical system of the motor vehicle. The interior of the motor vehicle can be heated if necessary by means of the emitted radiant heat. The thermal function layer is preferably made of a metallic and/or ceramic material.

In a further embodiment of the invention, the thermal function layer has an electric surface heating. Panel heating offers particular advantages in terms of energy efficiency.

In a further embodiment of the invention, a sound function layer is present and set up to emit sound signals. The sound signals that can be emitted by means of the sound function layer can be acoustic signals from the infotainment system of the motor vehicle, for example speech, music, signal tones, warning tones or the like. Alternatively or additionally, the sound signals can serve to reduce noise in the motor vehicle interior (noise cancellation).

In a further embodiment of the invention, the acoustic function layer has an acoustic membrane.

In a further embodiment of the invention, an absorption function layer is present and designed to absorb mechanical environmental influences and/or electromagnetic environmental influences. The absorption function layer therefore has a protective function. For example, the absorption function layer can serve as protection against splintering (mechanical environmental influences) or protection against eavesdropping (electromagnetic environmental influences/radiation influences). Alternatively or additionally, the absorption function layer can be set up to absorb airborne noise or structure-borne noise.

In a further embodiment of the invention, the light protection function layer is assigned a metal grid, the metal grid functioning as an absorption function layer and/or as a heat function layer and/or as a supporting structure. In one configuration, the metal grid is integrated into the functional light protection layer, for example laminated or otherwise embedded in the functional light protection layer. In a further configuration, the metal grid is applied to the functional light protection layer or vice versa. The metal grid can have different functions. For example, the metal grid can be set up to absorb mechanical, electromagnetic or other potentially harmful or undesirable environmental influences. Alternatively or additionally, the metal grid can be set up to give off electrically generated radiant heat. In this case, the metal grid acts as an electrical resistance heater and/or electrical panel heater. Alternatively or additionally, the metal grid can function as a supporting structure. In this case, the metal lattice gives the multilayer functional layer structure sufficient dimensional stability. The metal grid can be present as an alternative or in addition to the pane or the support frame according to the configuration explained above.

In a further embodiment of the invention, a functional covering layer is present and set up to cover the functional light protection layer and/or the at least one further functional layer in an opaque manner at least in sections. The covering function layer has in particular a covering function or also an ambience function. The covering and/or ambient function can give the surface structure and thus also the motor vehicle interior a specific look and/or feel. The cover function layer is preferably provided with a plurality of openings. The openings can have different sizes and can be arranged regularly or irregularly. The underlying layers of the multi-layer functional layer structure can be seen through the openings and/or can be reached manually. If the cover function layer is provided with said openings and is arranged in front of the information function layer in the direction of the motor vehicle interior, the impression of a starry sky can be created in particular. Of course, different optical impressions can also be presented here.

In a further embodiment of the invention, the functional cover layer is made of a textile material and/or leather. The look and/or feel of the fabric can be improved and easily adapted to the other properties of the motor vehicle interior by an appropriate choice of material for the covering function layer.

The invention also relates to an arrangement with a fabric as described above and with a control device, the control device being connected to the functional layer structure of the fabric and being set up to control at least one function of at least one of the functional layers of the functional layer structure. In one embodiment, the control device is integrated into the fabric. In a further embodiment, the control device is integrated into a superordinate construction module that encompasses the fabric. At a wide Ren embodiment, the control device is a central or decentralized control device of a motor vehicle, which is intended to be equipped with the fabric.

The invention also relates to a door module for a motor vehicle door with a window opening, having a fabric according to the preceding description or an arrangement according to the preceding description, a movement device operatively connected to the fabric, which is set up to move the fabric between a stowed position in which the fabric uncovers the window opening, and a functional position in which the fabric covers the window opening. In the stowed position, the fabric is lowered in the vertical direction relative to the window opening by means of the movement device. Preferably, the flat structure is completely lowered in the stowed position and is thus hidden from the view of a user. In the functional position, the fabric is shifted in the vertical direction in front of the window opening and a corresponding window pane of the motor vehicle door. The moving device can have a guiding device for the movable guiding of the fabric between the storage position and the functional position. Alternatively or additionally, the movement device can have a drive device, for example a rope or cable drive for driving the movement of the fabric between the storage position and the functional position. If the flat structure has a foldable LED display according to one of the preceding configurations, its separate carrier is preferably designed such that the LED display is automatically folded onto the supporting structure to save space when the flat structure is moved into the stowed position. The automatic folding in can be supported and/or effected by the design of the carrier and/or its articulation on the supporting structure.

The invention also relates to a motor vehicle with a flat structure according to the preceding description and/or an arrangement according to the preceding description and/or a door module according to the preceding description.

According to 1 a motor vehicle door 100 has a window opening 101 and is intended to be equipped with a door module 10 . The door module 10 can be installed in the factory on the motor vehicle door 100 in a manner known to those skilled in the art and is arranged in the installed state below the window opening 101 in the vertical direction.

The motor vehicle door 100 together with the door module 10 is part of a motor vehicle K, which is otherwise not shown in detail.

The motor vehicle door 100 shown is a rear side door of the motor vehicle K. The window opening 101 is accordingly a side window opening.

The door module 10 has a fabric 1, which in 1 is almost completely sunk into an unspecified module housing of the door module 10 and has a functional layer structure F described in more detail.

In addition, according to 1 a control device S is present, which interacts with the door module 10, more precisely: its fabric 1, in a manner that will be described in greater detail below. The fabric 1 and the control device S together form an unspecified arrangement. The control device S can be structurally assigned to the door module 10 or to the superordinate motor vehicle K. For example, the control device S can be a central or decentralized control device of the motor vehicle K.

How based on 2 and 3 as shown, the fabric 1 is between a stowed position ( 2 ) and a functional position movable ( 3 ). In the stowed position, the fabric 1 is lowered in the vertical direction under the window opening 101 and releases it. In the functional position, the fabric 1 is raised in the vertical direction to cover and/or shade the window opening 101 . It goes without saying that, in addition to the fabric 1, a window pane, not shown in detail, is provided for closing the window opening 101 so that it can be opened. The window pane and the fabric 1 can be moved independently of one another to open and close or to cover and uncover the window opening 101 . Preferably said window pane is closed when the fabric 1 is displaced into the operative position. This avoids that the fabric 1 is exposed to external influences such as moisture or the like.

In the present case, the door module 10 also has a movement device 200 for moving the planar structure 1 . In the embodiment shown, the movement device 200 is designed as a cable drive. The specific operation and design of the mover are not essential to the present invention.

In an embodiment not shown in the figures, the flat structure is arranged in the area of a front window or a rear window or a glass roof of the motor vehicle instead of in the area of the rear side door. Alternatively, the fabric can act as a partition between a rear and a driver's compartment of the motor vehicle. The must based on the 2 and 3 explained mobility of the fabric not be present in every embodiment. In particular in the case of an arrangement in the area of the front or rear window, the flat structure can be arranged in a stationary manner. Against this background, the basis of 1 until 3 shown arrangement of the fabric in the rear side door as a purely exemplary and not to be understood as limiting.

In the embodiment shown, the fabric 1 has a support structure 2 and a functional layer structure F ( 4 ).

The support structure 2 is transparent and dimensionally stable. At the in 4 In the embodiment shown, the support structure 2 is a pane 21 made of a translucent material. The pane 21 can be made, for example, of glass or another dimensionally stable but translucent material such as polycarbonate, Plexiglas or polymethyl methacrylate (PMMA). The support structure 2 carries the said functional layer structure F. The functional layer structure F is glued onto the pane 21 in the embodiment shown. Adhesive bonding methods, hot and/or chemical bonding methods known to the person skilled in the art are suitable for gluing the functional layer structure F onto the pane 21 .

In the present case, the functional layer structure F has a light protection functional layer 3 and a further functional layer in the form of an information functional layer 4 . The individual layers of the functional layer structure F are each extended over an area and arranged one on top of the other in the thickness direction of the fabric 1 .

The light protection functional layer 3 is set up to protect the motor vehicle interior from incident light and for this purpose can be electrically controlled between different light-transmitting states. In the embodiment shown, the functional light protection layer 3 has an electrically switchable film 33 with electrochromic properties, which can be designed, for example, as a PDLC film 31 (Polymer Dispersed Liquid Crystal) or SPD film 32 (Suspended Particle Device). Electrically switchable foils with electrochromic properties are known per se. In order to change the translucent properties of the functional light protection layer 3, more precisely: the switchable film 33, the functional light protection layer 3 is to be controlled with the control device S (see 1 ) effectively connected and controllable by means of this. For example, the switchable film 33 can be subjected to an operating voltage between 48 V and 100 V AC and thereby controlled and/or switched. The power supply can be fed from an electrical system of the motor vehicle K. The interior of the motor vehicle K can be shaded from incident light and/or, preferably completely, darkened by means of the functional light protection layer 3 . In addition, it is conceivable and possible for the functional light protection layer 3 to serve as a so-called “privacy screen” which protects the occupants of the motor vehicle K allows a view to the outside, while people outside of the motor vehicle K are prevented from looking inwards.

The information function layer 4 is primarily set up to display variable information I ( 6 ). The variable information can in particular be information such as is provided by an infotainment system of motor vehicle K, for example. Alternatively or additionally, the information I can cause and/or generate a decorative surface or a light display.

In the embodiment shown, the information function layer 4 has an LED display 41 in the form of an OLED film 42 . To control the function of the information function layer 4 there is a connection to the control device S in the present case. In an embodiment not shown in the figures, the LED display can be folded relative to the supporting structure between different positions about a folding axis.

5 shows a fabric 1 'as a variant of the fabric 1 after 4 . The flat structure 1' differs from the flat structure 1 only by a different design of the support structure. In the flat structure 1', the support structure has a support frame 22 with a first frame profile P1 and a second frame profile P2. The support frame 22 delimits a frame opening, not designated in any more detail, into which the functional layer structure F is inserted. In particular, the functional layer structure F is held and clamped between the frame profiles P1, P2 of the support frame 22. The frame profiles P1, P2 can, for example, be latched or clamped to one another in order to apply a corresponding clamping and holding force to the functional layer structure F. As an alternative or in addition, an overmoulding or foaming can be present to fix the functional layer structure to the support frame 22 .

The based on the 4 , 5 The functional layer structure F shown in FIG. 6 is to be understood as purely exemplary with regard to the functional layers 3, 4 included and their respective function. In different configurations, the functional layer structure F has different functional layers as an alternative or in addition to the light protection functional layer 3 and/or the information functional layer 4, as illustrated by way of example in FIG 7 until 12 are shown. The fabric can therefore have other functions as an alternative or in addition to the light protection function and the display function. The 7 until 12 show examples of other functional layers with different functions, in particular an input functional layer 5, a thermal functional layer 6, a sound functional layer 7, an absorption functional layer 8, a cover functional layer 9 and a generic functional layer 11. The said functional layers 5, 6, 7, 8, 9, 11 and 3 and 4 may be present in the fabric individually or in combination with each other. In addition, it is conceivable and possible that different functional layers and their function can be integrated into a common layer and/or layer.

The input function layer 5 is present for entering control commands B and has a touch-sensitive input surface 51 for this purpose. In the embodiment shown, the input surface 51 works with an inductive, capacitive and/or resistive operating principle. The input function layer 5 can also be referred to as a touch foil. The input function layer 5 and the information function layer 4 can be combined to form a common function layer and in this way form a touchscreen. The input function layer 5 allows a user to interact with the fabric 1 , with the control commands B that can be entered being provided, for example, for controlling an infotainment system of the motor vehicle K or for controlling the different functions of the fabric 1 .

The thermal function layer 6 is set up to emit radiant heat W generated electrically. The thermal function layer 6 primarily serves to improve comfort. The radiant heat W that can be emitted heats the vehicle interior. If the motor vehicle K has a separate heating device, the thermal function layer 6 serves to support said heating device. In the embodiment shown, the thermal function layer 6 has an electric surface heater 61 . The electric surface heating 61 can be made of a material suitable for this purpose, for example a metallic or ceramic material.

The sound function layer 7 serves to emit sound signals N into the motor vehicle interior. The sound signals N can be, for example, speech and/or music reproduction as well as the reproduction of warning or signal tones. Alternatively or additionally, the sound signals N can be used for so-called “noise canceling”. With such “noise canceling”, unwanted noise is counteracted by the emission of acoustically opposing sound signals.

In the embodiment shown, the acoustic function layer 7 has an acoustic membrane 71 . The acoustic membrane 71 is made and provided from a material suitable for acoustic purposes gend controlled by the control device S to emit the sound signals N.

The absorption function layer 8 is set up to absorb mechanical environmental influences U and/or electromagnetic environmental influences E. The absorption function layer 8 serves, for example, as protection against splintering. Alternatively or additionally, the absorption function layer 8 serves as protection against eavesdropping in the sense of an EMC surface.

The functional cover layer 9 is designed to cover the functional light protection layer 3 and/or at least one of the other functional layers described above in an opaque manner at least in sections. The functional covering layer 9 is preferably arranged as the uppermost layer of the functional layer structure F facing the motor vehicle interior. The functional cover layer 9 primarily serves to improve the feel and/or appearance of the fabric 1 . In the embodiment shown, the functional cover layer is made of a textile material 91 and/or leather 92 . Of course, different materials are also conceivable and possible for this purpose.

If the cover function layer 9 is combined with the display function layer 4 and/or the light protection function layer 3, the cover function layer 9 preferably has openings that are not shown in detail. Said openings can have different diameters and be arranged regularly or irregularly. In combination with the light protection function layer 3 and/or the display function layer 4, said perforation can create an optical impression in the form of a starry sky. Of course, different visual impressions are also conceivable and possible in this regard and can be generated via a corresponding design and arrangement of the openings.

The generic functional layer 11 has a further generic function which can preferably be controlled by means of an actuation via the control device S.

Based 13 another variant is shown, in which the functional light protection layer 3 of the fabric 1 is provided with a metal grid G. The metal grid G can have different functions. In the embodiment shown, the metal grid G serves to shape and stabilize the light protection functional layer 3 and thus the entire functional layer structure F. Alternatively or additionally, the metal grid G can function as an absorption functional layer, thermal function layer and/or support structure. The metal grid G serves in particular to protect people, for example against splinters. In addition, burglary protection and protection against vandalism can be present, since, for example, the pane 21 can break in the event of vandalism, but the metal grid G cannot. In addition, the overall visual impression of the fabric can be changed by patterns or embossing introduced into the metal grid G.

The metal grid G is particularly advantageous when the individual layers of the functional layer structure F are not inherently dimensionally stable and therefore sag in an unintended manner, especially when they are fixed to the support frame 22 . Such sagging is undesirable, particularly in the case of heavily curved side windows. The shape of the functional layer structure F can be adapted to the curvature of the side window—or any other window of the motor vehicle K—by means of a corresponding curved shape of the metal grid G.

It goes without saying that the individual functional layers 3, 4, 5, 6, 7, 8, 9, 11 can be connected to the control device S for the purpose of controlling and/or electrically switching their respective functionality. The connection can be wireless or wired. As an alternative or in addition to the connection to the control device S, a connection to the on-board electrical system of the motor vehicle K can be present. This in particular for the supply of electrical operating energy.
