[0002] Composite disc arrangement for a vehicle

[0003] The invention relates to a composite disc arrangement for a vehicle and a vehicle with the composite disc arrangement, as well as a method for manufacturing the composite disc arrangement and its use.

[0004] Laminated glass is used as windshields, rear windows, or roof windows in motor vehicles. It consists of at least one outer pane, a second inner pane, and an adhesive interlayer that bonds the outer pane to the inner pane. Typical interlayers are polyvinyl butyral films, which, in addition to their adhesive properties, offer high toughness and excellent acoustic damping. The interlayer prevents the laminated glass from shattering if damaged. The laminated glass may develop cracks but remains dimensionally stable.

[0005] To increase road safety, many vehicles have additional brake lights inside the vehicle. Vehicles are known from the prior art that have a single, raised brake light mounted near the rear window. This raised brake light is usually an additional light to the two brake lights located on the sides of the vehicle.

[0006] From DE 102 17 490 B4, a motor vehicle with a brake light located at the upper edge of the rear window is known. The brake light is positioned behind the upper edge of the rear window, facing the vehicle interior. When the brake light is activated, a light signal shines through the rear window. The brake light is concealed from the vehicle interior by an interior trim panel. This requires considerable installation effort, particularly with regard to the electrical wiring. A further disadvantage of this arrangement is that the light emitted from the additional brake light is less intense and of a lower color when viewed from the outside compared to the other two side-mounted brake lights of the vehicle, as the rear window acts as a disruptive light filter.Furthermore, the brake light and its electrical connections are positioned far from the rear window, so that light reflections on the rear window are disturbingly visible to the driver in the rearview mirror.

[0007] From WO 2008 / 058881 A1, an automotive glazing with a non-galvanic contact for an electrical device connected to the glazing is known. SAINT-GOBAIN SEKURIT FRANCE 2025009- WO-PCT 2

[0008] The object of the present invention is to provide a composite lens assembly for a vehicle that allows for the simple mounting and connection of an electrical component, in particular a brake light. Furthermore, it is an object of the invention to provide a method for manufacturing such a composite lens assembly.

[0009] This problem is solved by a composite disc arrangement according to independent claim 1, as well as by a vehicle according to claim 10 and a method according to claim 11. Preferred embodiments are set forth in the dependent claims.

[0010] The composite disc arrangement according to the invention for a vehicle comprises a first disc with a first surface and a second surface, a second disc with a first surface and a second surface, and a thermoplastic intermediate layer that bonds the first disc and the second disc together to form a composite disc. Furthermore, the composite disc arrangement includes a transmission arrangement for inductive energy transfer. The transmission arrangement comprises a primary coil and a secondary coil, wherein the first disc and / or the second disc of the composite disc is arranged between the primary coil and the secondary coil. The transmission arrangement is particularly designed for inductive energy transfer between the primary coil and the secondary coil arranged on an outer surface of the composite disc.In inductive power transfer, electrical energy is transferred contactlessly from the primary coil to the secondary coil, which is typically located on the outside of the lens. This allows an electrical component, such as a brake light, to be directly attached to the lens and powered. This arrangement ensures that energy transfer occurs through the lens itself, eliminating the need for additional drilling for power cables.

[0011] According to the invention, the primary coil can be connected to at least two electrical leads, which connect the primary coil to a power supply device. The leads can, for example, be arranged between the first and second disks. A first end of each electrical lead is electrically connected to a power supply, and a second end of the electrical lead contacts the primary coil. SAINT-GOBAIN SEKURIT FRANCE 2025009- WO-PCT 3

[0012] A further advantage of the composite disc arrangement according to the invention is the flexible positioning of the transmission arrangement and thus of the electrical component on the composite disc. Since the positioning of the transmission arrangement on the first disc and / or second disc is freely selectable, several electrical components can be attached to the composite disc, radiating in a wide variety of directions.

[0013] The secondary coil preferably has a connection for an electrical component, in particular a lighting device, a camera, a GPS module, and / or a sensor module. Preferably, the external secondary coil is connected to electronics, which include, for example, a rectifier, a capacitor, and / or an inverter. Preferably, the electronics are connected to the electrical component, in particular the brake light. In one installation position of the composite windscreen in a vehicle, the brake light can then be positioned directly on the outer surface of the composite windscreen and shine towards the surrounding environment. This makes the brake light clearly and distinctly visible to an observer in the vicinity. The brake light mounted on the composite windscreen gains in luminous intensity and color, exhibiting the same luminous intensity and color as the other two laterally arranged brake lights of the vehicle.The composite disc arrangement according to the invention for a vehicle can thus contribute significantly to increasing the road safety of a vehicle.

[0014] A transparent, electrically conductive layer, visible to the naked eye, is applied to the first and / or second pane. This ensures that the laminated pane has additional functionality and that the view through the central viewing area of ​​the laminated pane is enhanced.

[0015] Advantageously, the at least two electrical leads are formed from the electrically conductive layer. The at least two electrical leads can preferably be arranged on the second surface of the first pane or on the first surface of the second pane. The transparency of the electrical leads allows an unobstructed view through the composite pane.

[0016] Additionally, the electrical supply line can be designed at least partially or completely as a wire, a cable, or a metal strip, in particular a copper strip. The electrical supply line can be laminated into the thermoplastic interlayer. Arranging the electrical supply line within the thermoplastic interlayer is advantageous because the supply line is then less visually conspicuous and protected against mechanical damage. SAINT-GOBAIN SEKURIT FRANCE 2025009- WO-PCT 4

[0017] The wire may additionally have a lacquer coating. Straight resistance wires are also possible as leads. The electrical leads preferably consist of wires running horizontally or vertically, essentially parallel to each other, with a diameter of approximately 20 pm to 200 pm, preferably 90 pm, and particularly preferably 20 pm to 30 pm. They run essentially perpendicular to a disc edge. Various configurations of the leads are conceivable, e.g., with leads running only horizontally or vertically. The wire is designed to be particularly thin so that it does not, or only minimally, impair the view through the composite disc. The wire may additionally have electrical insulation made of plastic. Such an arrangement eliminates the need for an additional inner lining component on the composite disc.

[0018] The electrical supply line can be designed, at least partially, as a wire, a cable, a foil conductor or a metal strip, in particular a copper strip.

[0019] Examples of foil conductors are described in DE 4235063 A1, DE 202004019286 U1 and DE 93 13 394 U1. Flexible foil conductors, sometimes also called flat conductors or flat ribbon conductors, preferably consist of a tinned copper strip with a thickness of 0.03 mm to 0.1 mm and a width of 2 mm to 16 mm. Copper has proven suitable for such conductors because it has good electrical conductivity and is easy to process into foils. At the same time, the material costs are low. Other electrically conductive materials that can be processed into foils can also be used. Examples include aluminum, gold, silver, or tin and alloys thereof.

[0020] Preferably, two busbars serve as power supply conductors and extend at least partially along an edge of the first or second disk. The first end of each electrical supply line is electrically connected to a busbar, and the second end of the supply line contacts the primary coil. Alternatively, the two busbars can extend along two opposite edges of the first or second disk (for example, the bottom and top edges, or the right and left edges). Furthermore, the busbars can be positioned at a distance from an edge. Often, the busbars are positioned near the edge, i.e., not centrally within the interior of the composite disk. Additionally, a cover layer is applied in the area of ​​the busbars to conceal the individual busbars, or a large cover layer can be provided that also covers the supply lines.SAINT-GOBAIN SEKURIT FRANCE 2025009-WO-PCT 5.

[0021] The collector conductors can be electrically connected to a voltage source via a foil conductor leading out of the composite disc.

[0022] In a further advantageous embodiment of the composite disc arrangement according to the invention, the busbars are located on at least one of the surfaces, in particular an inner surface, of the first and / or second disc. Alternatively, the busbars can be integrated into the intermediate layer. The busbars are then preferably applied to a carrier film. The carrier film preferably contains a polymer, in particular polyvinyl butyral (PVB), ethylene vinyl acetate (EVA), polyurethane (PU), polyethylene terephthalate (PET), or combinations thereof.

[0023] The busbars can each be designed as a printed, electrically conductive paste, preferably a silver-containing screen-printing paste, or as an electrically conductive conductor, preferably made of metal, and in particular copper, silver, gold, or aluminum. Copper has proven suitable for such conductors due to its good electrical conductivity. At the same time, copper is inexpensive to use. The busbars can be made of tinned copper foil strips. The busbar can also be, for example, in wire form or as a flat conductor. The busbars are also referred to as busbars. The electrical leads are electrically connected to the busbars in such a way that when an electrical voltage is applied to the busbars, a current can flow through the electrical leads if the lead is in contact with the primary coil.

[0024] In a further advantageous embodiment, the laminated glass pane has an electrical component attached to the pane containing the secondary coil. This electrical component can comprise any electrically controllable devices used in automotive glazing that can be mounted on an outer surface of the laminated glass pane. The electrical component can be configured as a lighting device. This lighting device can be a brake light, a turn signal, a reversing light, and / or a rear fog light, and may additionally include a camera, a GPS module, or a sensor module.

[0025] In a further advantageous embodiment, the composite pane has an opaque cover layer on the second surface of the first pane or on the first surface of the second pane, at least in an edge region along a first edge of the first pane or the second pane. SAINT-GOBAIN SEKURIT FRANCE 2025009- WO-PCT 6

[0026] Preferably, the secondary coil is arranged on the first surface of the first disc, particularly when the first disc is installed as the outer disc of a vehicle. The second surface of the first disc faces the intermediate layer. The composite disc then does not act as a light filter in the beam path of the brake light. Alternatively, an embodiment in which the secondary coil is arranged on the second disc (inner disc) is possible.

[0027] It is further preferred that the primary coil is arranged between the first disk and the second disk, in particular on the second surface of the first disk or on the first surface of the second disk.

[0028] To achieve optimal energy transfer efficiency, the secondary coil must be correctly aligned and positioned relative to the primary coil so that the primary and secondary coils are in complete overlap. It is particularly advantageous to position the primary coil on the second surface of the first disk, as this results in a smaller distance between the coils and thus increases the efficiency of the inductive energy transfer. The electrical supply line is then located on the second surface of the first disk or on the first surface of the second disk. This arrangement is especially advantageous because the primary coil and the electrical supply line are protected from external weather conditions.

[0029] In a particularly preferred embodiment of the composite window arrangement according to the invention, the composite window is designed as a rear window, a roof window, a side window or a front window of a vehicle, preferably as a combined roof and rear window.

[0030] In a preferred embodiment, the laminated glass arrangement can be designed as vehicle glazing, in particular as a combined roof and rear window. According to the invention, the combined roof and rear window is a roof window that has been significantly extended so that the roof window encompasses the rear window and is formed as a single piece. The roof and rear window provides the occupants with an extended vertical field of vision.

[0031] In one possible embodiment, the electrical component is mounted on a bracket. The composite disc is then connected to the bracket via an adhesive bond. The electrical component with the bracket has a width and / or height between 2 cm and 50 cm, preferably between 5 cm and 20 cm. The adhesive layer SAINT-GOBAIN SEKURIT FRANCE 2025009- WO-PCT 7

[0032] The adhesive can be an adhesive, in particular an electrically conductive one. Bonding of the mounting device to the laminated lens can be carried out after a lamination process. Preferably, the electrical component is reversibly fixed in the mounting device, thus simplifying its replacement. The brake light, as a component integrated into the mounting device, can be oriented in various directions and, for example, emit light diffusely towards the surroundings of the vehicle in which the laminated lens is installed.

[0033] The thickness of the first and / or second pane can vary widely and thus be ideally adapted to the requirements of the individual case. Standard thicknesses of 1.0 mm to 25 mm are preferably used, and more preferably 1.4 mm to 2.5 mm for vehicle glass. The size of the panes can vary widely and depends on the scale of the application according to the invention. The first and second panes, for example, have areas of 200 cm², which are common in vehicle construction. 2 up to 2 m 2 on.

[0034] The composite disc can have any three-dimensional shape. Preferably, the three-dimensional shape has no shadowed areas, so that it can be coated with further coatings, for example, by cathode sputtering. Preferably, the discs are planar or slightly or strongly curved in one or more directions. Planar substrates are particularly well-suited. The discs can be colorless or colored.

[0035] The first and second panes preferably contain or consist of glass, particularly preferably flat glass, float glass, quartz glass, borosilicate glass, soda-lime glass, aluminosilicate glass, or clear plastics, preferably rigid clear plastics, in particular polyethylene, polypropylene, polycarbonate, polymethyl methacrylate, polystyrene, polyamide, polyester, polyvinyl chloride and / or mixtures thereof. The first and second panes can be clear and colorless, but also tinted or colored.

[0036] The first and second panes are bonded together by at least one thermoplastic interlayer. The interlayer is preferably transparent, tinted, or colored. The interlayer preferably contains or consists of at least one plastic, preferably polyvinyl butyral (PVB), ethylene vinyl acetate (EVA), and / or polyethylene terephthalate (PET). However, the interlayer can also be, for example, polyurethane (PU), polypropylene (PP), polyacrylate, polyethylene (PE), polycarbonate (PC), polymethyl methacrylate, polyvinyl chloride, polyacetate resin, casting resins, acrylates, fluorinated ethylene propylenes, polyvinyl fluoride, and / or ethylene tetrafluoroethylene, or copolymers.

[0037] The interlayer contains mixtures thereof. The interlayer can be formed by one or more superimposed films, the thickness of which is preferably 0.025 mm to 1 mm, typically 0.38 mm or 0.76 mm. The interlayers are thermoplastic and, after lamination, can bond the first pane, the second pane, and any further interlayers together. Particularly advantageous are so-called acoustic-damping interlayers, which preferably consist of three layers of PVB, with the middle layer being softer than the two outer layers.

[0038] The intermediate layer can also be a functional intermediate layer, in particular an infrared radiation-reflecting intermediate layer, an infrared radiation-absorbing intermediate layer, a UV radiation-absorbing intermediate layer, an intermediate layer that is at least partially colored, and / or an intermediate layer that is at least partially tinted. For example, the thermoplastic intermediate layer can also be a bandpass filter film.

[0039] The terms "first pane" and "second pane" are chosen to distinguish between the two panes in a composite pane according to the invention. These terms do not imply anything about the geometric arrangement. If, for example, the composite pane arrangement according to the invention is intended to separate the interior from the external environment in an opening, such as in a vehicle, the first pane can face either the interior or the external environment. Preferably, the first pane, as the outer pane, faces the external environment.

[0040] The first pane and / or the second pane may have further suitable coatings known per se, for example anti-reflective coatings, non-stick coatings, anti-scratch coatings, photocatalytic coatings or sun protection coatings or low-E coatings.

[0041] Furthermore, the composite disk may include additional functional elements, in particular electronically controllable optical elements, for example electro-optical functional elements (SPD = Suspended Particle Device, known, for example, from EP 0876608 B1 and WO 2011033313 A1, or PDLC = Polymer Dispersed Liquid Crystal), electrochromic elements, or similar, which are typically arranged between the first disk and the second disk. SAINT-GOBAIN SEKURIT FRANCE 2025009- WO-PCT 9

[0042] In a preferred embodiment of the composite disc arrangement, the second surface of the first disc has an opaque cover layer, at least in one, and in particular circumferential, edge region of the composite disc. The opaque cover layer faces the thermoplastic intermediate layer. This protects the opaque cover layer from external weather influences. The opaque cover layer can be arranged directly or indirectly on the disc surface. The edge region borders and extends along at least one edge of the first disc. When viewed perpendicularly from the outside, the opaque cover layer obscures the view of the busbars. The busbars are arranged at least partially within the area of ​​the cover layer. The busbars can be applied directly or indirectly, preferably directly, to the opaque cover layer.

[0043] The opaque cover layer is optionally widened in at least one area. This means that the opaque cover layer has a greater width perpendicular to the nearest section of the perimeter edge of the composite panel than in other sections. The opaque cover layer is preferably formed around the perimeter edge of the composite panel, with the width of the cover layer varying.

[0044] The at least one opaque cover layer according to the invention is a layer that prevents visibility through the composite pane. The opaque cover layer allows a transmission of at most 5%, preferably at most 2%, particularly preferably at most 1%, and especially at most 0.1% of the visible spectrum. The opaque cover layer can be formed across the entire surface; alternatively, the cover layer can be semi-transparent, for example, as a dot matrix, stripe matrix, or grid. Additionally, the cover layer can have a gradient, for example, from an opaque layer to a semi-transparent layer.

[0045] The opaque coating can be, for example, an opaque enamel or an opaque lacquer. The opaque coating preferably contains at least one pigment and glass frits. It may also contain other chemical compounds. The glass frits can be partially or fully fused to the glass surface, thereby permanently bonding (fusion- or sintering) the coating to the glass surface. The pigment provides the opacity of the coating. Such coatings are typically applied as enamel. SAINT-GOBAIN SEKURIT FRANCE 2025009- WO-PCT 10

[0046] Such opaque coatings are also known as screen printing or black print. A printing ink, from which the opaque enamel-like coating is formed, preferably contains at least the pigment and the glass frits suspended in a liquid phase (solvent), for example, water or organic solvents such as alcohols. The pigment is typically a black pigment, for example, carbon black, aniline black, bone black, iron oxide black, spinel black, and / or graphite.

[0047] Alternatively or additionally, the thermoplastic intermediate layer can also be colored to cover the view of the collector conductors in the edge area.

[0048] Another aspect of the invention relates to a vehicle comprising a composite disk arrangement according to the invention with a transmission arrangement for inductive energy transmission, wherein the transmission arrangement comprises a primary coil and a secondary coil, and wherein the first disk and / or the second disk is arranged between the primary coil and the secondary coil.

[0049] Preferably, the first disk has the secondary coil, wherein the first disk is designed as an outer disk of the vehicle and an electrical component is arranged on the first surface of the first disk (outer side) which is electrically connected to the secondary coil.

[0050] The laminated glass arrangement is designed to separate the interior from the external environment in a window opening, particularly a vehicle window opening. For the purposes of the invention, the term "inner pane" refers to the pane of the laminated glass facing the interior. The term "outer pane" refers to the pane facing the external environment.

[0051] The invention further comprises a method for manufacturing a composite disk arrangement according to the invention with a transmission arrangement, comprising at least the following method steps:

[0052] • Providing a first disk, a second disk and the transmission arrangement for inductive power transfer, wherein the transmission arrangement comprises a primary coil and a secondary coil, SAINT-GOBAIN SEKURIT FRANCE 2025009- WO-PCT 11

[0053] • Providing a thermoplastic intermediate layer and two electrical leads,

[0054] • Connecting the two electrical leads to the primary coil,

[0055] • Forming a layer stack, wherein the layer stack comprises at least in this order the first disk, the thermoplastic intermediate layer and the second disk, wherein the first disk and / or the second disk is arranged between the primary coil and the secondary coil, and

[0056] • Combining the stack of layers consisting of at least the first disk, thermoplastic intermediate layer and second disk to form a composite disk.

[0057] The first and second discs can be bent individually. Preferably, the first disc (outer disc) and the second disc (inner disc) are bent congruently together (i.e., simultaneously and using the same tool) because this ensures that the shape of the discs is optimally matched for subsequent lamination. Bending the discs preferably takes place before lamination.

[0058] In a further embodiment of the method according to the invention, an opaque cover layer is applied first, followed by the busbars. In this embodiment, the busbars are thus only present in the area where the opaque cover layer is located. The opaque cover layer is preferably applied to the first surface of the second disk, the one facing the intermediate layer. Alternatively or additionally, the opaque cover layer can be applied to the second surface of the first disk, the one facing the intermediate layer.

[0059] The bonding of the first and second panes to form a composite pane via the thermoplastic interlayer is preferably achieved by lamination. The thermoplastic interlayer is preferably provided as a film. The composite pane is produced by lamination using conventional methods known to those skilled in the art, such as autoclave processes, vacuum bag processes, vacuum ring processes, calender processes, vacuum laminators, or combinations thereof. The bonding of the first and second panes occurs under the influence of heat, vacuum, and / or pressure.

[0060] The electrical component with mounting device is preferably attached after lamination of the composite glass. SAINT-GOBAIN SEKURIT FRANCE 2025009- WO-PCT 12

[0061] Another aspect of the invention includes the use of a composite glass arrangement according to the invention as vehicle glazing in means of transport for traffic on land, in the air or on water, preferably as vehicle glazing in rail vehicles or motor vehicles, in particular as vehicle glazing of passenger cars.

[0062] The embodiments of the composite disc arrangement described above also apply accordingly to the method for manufacturing a composite disc arrangement according to the invention and vice versa.

[0063] The invention is explained in more detail below with reference to figures and exemplary embodiments. The figures are schematic representations and not to scale. The figures do not limit the invention in any way. It should be noted that different aspects are described, which can be used individually or in combination.

[0073] Figure 1 shows a schematic view of a composite disc arrangement 100 according to the invention. The composite disc arrangement 100 comprises a composite disc 10 with an electrical component 9, for example, a brake light of a vehicle. The composite disc 10 is designed to separate the interior 12 (Figure 2) of the vehicle from the external environment 13 within a window opening of the vehicle. For the sake of simplicity, the composite disc 10 is shown in planar form, although composite discs are typically curved in reality. The composite disc 10 has an edge K. Two busbars as current supply conductors can extend at least partially along the edge K.

[0074] Figure 2 shows a schematic view of the composite disk arrangement 100 according to the invention in section Z. The composite disk arrangement 100 comprises the composite disk 10 with a transmission arrangement 4 for inductive energy transmission.

[0075] The composite disc 10 comprises a first disc 1 with a first surface I and a second surface II, a second disc 2 with a first surface III and a second surface IV, and a thermoplastic intermediate layer 3 that connects the first disc 1 and the second disc 2. An electrically conductive layer 3.2, transparent to visible light, can be arranged on the first disc 1 and / or the second disc 2.

[0076] The transmission arrangement 4 comprises a primary coil 4.1 and a secondary coil 4.2. Both the primary coil 4.1 and the secondary coil 4.2 have multiple turns. The primary coil 4.1 is located on the first disk 1, specifically on the first surface I of the first disk 1. The primary coil 4.1 is connected to a power supply unit via two leads 5. The secondary coil 4.2 is inductively coupled to the primary coil 4.1 and is located on the second surface IV of the second disk 2. The secondary coil 4.2 supplies power to the attachment 9. The secondary coil 4.2 is provided with a connection for an electrical attachment 9, specifically a lighting device.

[0077] Along edge K (Figure 1) of the first disk 1, two busbars can be arranged as current supply conductors. The busbars are strip-shaped and SAINT-GOBAIN SEKURIT FRANCE 2025009- WO-PCT 14

[0078] The two busbars are spaced apart from each other. Both busbars are arranged at a small distance of approximately 1 cm, 2 cm, or 5 cm from edge K. The two busbars are separated by a high-impedance conductor. Each busbar is formed as a printed, electrically conductive, silver-containing screen-printed paste. Preferably, the busbars are applied by screen-printing a heat-setting paste and then baked on. Alternatively, the busbars can be formed from tinned copper foil strips. A busbar can also be, for example, in wire form or as a flat conductor.

[0079] The busbars can be electrically connected to a voltage source via a foil conductor extending from the composite disc 10. Furthermore, the busbars can be functionally connected to a control and / or regulating unit, for example, to the on-board electronics of a vehicle.

[0080] Furthermore, the composite disk 10 has two electrical leads 5 arranged on the first surface I of the first disk 1. The composite disk 10 can also have three or four electrical leads 5. A first end of each electrical lead 5 is electrically connected to a busbar, and a second end of each electrical lead 5 is connected to the primary coil 4.1.

[0081] The electrical leads 5 are made of the electrically conductive layer 3.2 or are formed as a wire or cable. Alternatively or additionally, the leads 5 can be designed as foil conductors or metal strips, in particular copper strips. The wire can additionally have a coating of lacquer. The electrical leads 5 consist of horizontally running, essentially parallel wires, which have a diameter of about 20 pm to 200 pm, for example 100 pm [micrometers].

[0082] Each electrical supply line 5 is arranged between a busbar and the primary coil 4.1. The electrical supply lines 5 are electrically connected to the busbars in such a way that when an electrical component 9 is connected to the supply lines 5 and an electrical voltage is applied to the busbars, a current can flow through the electrical supply lines 5.

[0083] The second surface II of the first pane 1 and / or the first surface III of the second pane 2 can have an opaque cover layer at least in an edge region 7 along the first edge K of the first pane 1 or the second pane 2 of the composite pane 10. The opaque cover layer is applied in a frame-like manner in a circumferential edge region. The edge region and the cover layer can have a width of approximately 20 mm. SAINT-GOBAIN SEKURIT FRANCE 2025009- WO-PCT 15

[0084] They have a thickness of 200 mm. The cover layer is opaque and, when viewed vertically from the outside, conceals the view of the busbars.

[0085] The first surface III of the second disc 2 can have a protective layer, at least in its surrounding edge area. This protective layer also serves as protection against UV radiation. The protective layer is optionally widened in at least one area. The opaque protective layer can, for example, be an opaque enamel or an opaque lacquer.

[0086] The distribution board is to be positioned at the perimeter (7), i.e., not centrally located within the interior. A cover layer was applied in the area of ​​the distribution board to conceal the individual boards. Additionally, a larger cover layer may be provided that also covers the supply lines (5).

[0087] In one embodiment of the inventive method for producing a composite disk 10, the opaque cover layer is applied first, followed by the busbars. In this embodiment, the busbars are therefore only present in the area where the opaque cover layer is located. The opaque cover layer can additionally be applied to the first surface III of the second disk 2, the surface facing the intermediate layer 3.

[0088] Figure 3 shows the composite disc arrangement 100 from Figure 2 in section Z, wherein the composite disc 10 is equipped with an electrical attachment 9, for example a brake light of a vehicle.

[0089] Figure 4 shows a schematic view of another embodiment of the composite disc arrangement 100 according to the invention.

[0090] The first pane 1 has surface I and surface II. The second pane 2 has surface III and surface VI. The thermoplastic interlayer 3 bonds surface II of the first pane 1 to surface III of the second pane 2. The composite pane 10 is used as the rear window of a motor vehicle. Alternatively, the composite pane 10 can be used as a roof and rear window, where the roof and rear window is a combined roof and rear window, i.e., the roof window has been significantly extended so that it encompasses the rear window.

[0098] Figure 6 shows a further embodiment of the composite disk arrangement 100 according to the invention in detail Z. The composite disk arrangement 100 comprises the composite disk 10 with a transmission arrangement 4 for inductive energy transmission. Unlike in Figure 2, the primary coil 4.1 is arranged on the second disk 2, in particular on the second surface IV of the second disk 2.

[0100] Figure 8 shows a schematic view of the second disk 2 from Figure 4. The transmission arrangement 4 comprises the primary coil 4.1 and the secondary coil 4.2. The primary coil 4.1 is arranged on the first surface III of the second disk 2. The primary coil 4.1 is connected to a power supply unit via two leads 5, the leads 5 being arranged on the first surface III of the second disk 2. The secondary coil 4.2 is inductively coupled to the primary coil 4.1 and is arranged on the second surface IV of the second disk 2. Figure 9 shows the disk 2 with an electrical attachment 9.

[0101] A particular advantage of the invention is the inductive energy transfer. Such energy transfer enables a compact design of the composite lens assembly, as the transfer arrangement saves installation space compared to conventional designs. Furthermore, the assembly effort, especially the wiring of such an add-on component, is reduced, and its energy consumption is optimized. Energy efficiency is an extremely important criterion for future product developments. Advantageously, the arrangement of the brake light on the first or second lens increases the perceived luminous intensity and color of the brake light, so that it produces the same luminous intensity and color as the other two laterally arranged brake lights of the vehicle. Because all brake lights have the same luminous intensity, this offers advantages for SAINT-GOBAIN SEKURIT FRANCE 2025009- WO-PCT 18
