    [0001] This invention relates to an electrically heated window, in particular to an electrically heated laminated window, comprising a grid of at least one electrically conductive path connected to a film, its method of manufacture and its use. This invention also relates to a vehicle incorporating said electrically heated window.
    [0002] Electrically heated windows are normally used as windshields or taillights in vehicles, in order to be able to defog or defrost the window in conditions of cold and / or humid weather. For windows used as a windshield for a vehicle, electric heating media are generally provided as a network of thin wires (with a diameter of less than 30 micrometers), closely spaced (a distance of 1 mm to 3 mm between wires) . Although the wires in this network are generally parallel, each is normally provided with ripples, such as crimping in a sinusoidal, helical, zigzag or random pattern, to avoid the effects of glare and polarization, when objects are seen through the window by a vehicle driver.
    [0003] Heating functionality has traditionally been provided by incorporating tungsten heating elements into a laminate, as described in EP 0 788 294, or by including a conductive coating (for example, sprayed on an internal surface of
    Petition 870190042607, of 05/06/2019, p. 4/45
    2/18 glass, as described in international patent WO 00/76930, or on a separate plastic (PET) substrate. The tungsten wired product has the disadvantage of wire visibility, which can hinder vehicle drivers, especially if sections of a window, such as sections of a windscreen adjacent to A-pillars of a car, do not contain the wire. tungsten and therefore some original equipment manufacturers do not like the existing wired product. The coated, heated product normally requires a supply voltage higher than the standard 12.0 / 13.0 Volts, due to the leaf resistivity of the conductive coating (for example, 42 Volts), to achieve sufficient power density to defrost the windshield.
    [0004] Consequently, there is a need to provide electrically heated windows, which improve visibility, which is displayed through existing heated windows, wired with tungsten. It is also desirable to provide electrically heated windows, which meet the legal requirements for light transmission, can be adjusted to suit a special power supply (nominally 12 / 13.0 Volts), provide a durable product (provision of warranty ), reduce undesirable heating inside a vehicle (by providing solar control properties), and allow the simple incorporation of devices, such as wiper defrosters, windows with heated chambers and toll sensors.
    [0005] According to a first aspect of the present invention, an electrically heated window is provided, comprising:
    at least two layers of a glazing material; at least one layer of an interlayer material;
    Petition 870190042607, of 05/06/2019, p. 5/45
    3/18 a grid of at least one electrically conductive path connected to a film; and electrical connection means to supply current to the grid, in order to heat the window;
    wherein at least one layer of an interlayer material, the grid and film are laminated between at least two layers of a glazing material.
    [0006] It should be clear that, in the context of the present invention, grid means a structure of at least one electrically conductive interlaced or parallel path, based on, for example, square, rectangular, triangular, hexagonal and / or cells rhombus shape. At least one track can be of any suitable shape, such as straight, curved or sinusoidal. This arrangement is advantageous because it allows the grid to work more easily coextensively with the layers of a glazing material. In an existing heated window, wired with tungsten, the shape of the window may not allow the same length of tungsten wire to be incorporated along the window, as in the sections of a windshield adjacent to the A-pillars of a car. This can affect the local energy density reached due to the differences between the resistances of the wires with different lengths. This creates regions of changing temperature, known as hot spots. The presence of one or more hot spots in a window is highly undesirable for two reasons: first, there is a risk that occupants of a vehicle, in which the window is installed, may touch the window, in the region of one or more more hot spots, causing injuries; and, second, there is a risk that the window will be locally delaminated in the region of the hot spots. This results in regions of the window
    Petition 870190042607, of 05/06/2019, p. 6/45
    4/18 having reduced or no visibility.
    [0007] The use of a grid solves this problem, since it effectively forms a resistive sheet, which allows current paths, of approximately equal length, to be obtained between the electrical connection means, for example, on opposite edges of a windshield.
    [0008] Preferably, the grid is a square or rectangular cell structure.
    [0009] The grid can be substantially coextensive within the two layers of a glazing material.
    [00010] At least one electrically conductive pathway can be manufactured from a material selected normally from the group consisting of silver, copper, gold, or aluminum. Other low-resistivity metals typically less than 8 x 10 - may be suitable, so that they can provide the necessary sheet resistance of 0.1 to 1.0 ohm-square, while maintaining adequate visibility. Preferably, at least one electrically conductive path is silver.
    [00011] The film may be a polymer film. The polymer film can be selected from the group, consisting of polyethylene terephthalate (PET), polyethylene (PE), cross-linked polyethylene (PEX), polyphenyl ether (PPE), polyvinyl chloride (PVC), polyvinylidene chloride (PVDC), polylactic acid (PLA), polypropylene (PP), polybutylene (PB), polybutylene terephthalate (PBT), polyamide (PA), polyimide (PI), polycarbonate (PC), polytetrafluoroethylene (PTFE), polystyrene (PS ), polyurethane (PU), polyester (PES), acrylonitrile-butadiene-styrene (ABS), polymethyl methacrylate (PMMA), polyoxymethylene (POM), polysulfone (PES), styrene acrylonitrile (SAN), ethylene vinyl acetate ( EVE),
    Petition 870190042607, of 05/06/2019, p. 7/45
    5/18 and maleic-styrene anhydride film. Preferably, the polymer film is polyethylene terephthalate.
    [00012] The film may have a thickness of less than 200 micrometers, preferably less than 100 micrometers, more preferably, less than 75 micrometers, even more preferably, less than 50 micrometers and, more preferably, less than 30 micrometers . A thinner film can be advantageous, because the thicker the film, the more likely it is that laminating in complex shapes will result in film wrinkling.
    [00013] The interlayer material can be selected from the group consisting of polyvinyl butyral (PVB), ethylene-vinyl acetate (EVA) and other polymeric interlayer.
    [00014] The window can have a light transmission of at least 70%, preferably at least 75%, as for windshields. The window can have a light transmission of less than 75%, as for bodyglass.
    [00015] The window may have an opacity of less than 7%, preferably less than 6%, more preferably less than 5%.
    [00016] The window can typically have a resistance of 0.1 to 1.0 ohm / square. This is advantageous, because the resistance can be adjusted to satisfy a required power density (for anti-fog or defrost functionality), such as a 12.0 to 13.0 V voltage source, which is used in a number of vehicles.
    [00017] The electrical connection means can comprise at least two busbars. These two busbars can be laminated between at least two layers of a glazing material.
    Petition 870190042607, of 05/06/2019, p. 8/45
    6/18 [00018] The electrical connection means may also comprise an electrical connector connected to at least one of at least two busbars.
    [00019] To connect the grid to a power source, it is necessary to obtain a good mechanical and electrical interface. This can be achieved using traditional copper busbars (already used inside wired, heated laminates). The incorporation of the bus can be achieved by bonding the bus to one of at least two layers of a glazing material.
    [00020] At least one of the busbars can be coated with a solder. It is advantageous to coat the busbars with a weld, which gives a good electrical contact to the grid. The solder can be a solder containing silver (with flux). Such a weld will give a good electrical interface to the grid. The weld can have a low melting point (<140 ° C), such that the weld flows to form a welded joint during a rolling process (see EP 1 110
    431 on secure buses).
    [00021] At least one of the busbars can be crimped, or have raised areas. This arrangement is beneficial, as it gives a point of contact with improved pressure, with the grid.
    [00022] At least one of the busbars can be coated with a conductive adhesive. This bus can be glued over the grid and the film. This arrangement provides good electrical contact and sufficient bonding strength to keep the busbar in position over the grid and the film during window assembly.
    [00023] Alternatively, at least one of the busbars can be a silver printed bus, which can be incorporated over one of at least two layers of
    Petition 870190042607, of 05/06/2019, p. 9/45
    7/18 pane on an interior laminating surface to give mechanical contact with the grid attached to the film during assembly.
    [00024] The grid attached to the film may further comprise a coating of at least one electrical conductor, such as copper and / or nickel. Such a coating can be advantageous, because it can improve the solar control properties of the window, due to its reflection properties. At least one crimped rail can be used to allow the raised dots on at least one rail to break through the liner during lamination. This arrangement improves the quality of the interface between the grid and at least one bus.
    [00025] Such coating on the grid can be removed mechanically (using abrasion) or chemically. Removing the coating improves the quality of the interface between the grid and at least two busbars.
    [00026] The grid can have an increased surface area of at least one electrically conductive path in a region adjacent to at least one bus. This arrangement improves the quality of the interface between the grid and at least one bus.
    [00027] The grid can have an increased thickness of at least one electrically conductive path in a region adjacent to at least one bus. It should be clear that, in this context, thickness means the height of at least one electrically conductive path from a polymer film binding surface. This arrangement improves the quality of the interface between the grid and at least one bus, improving weldability. The thickness of at least one route
    Petition 870190042607, of 05/06/2019, p. 10/45
    8/18 electrically conductive in regions not adjacent to at least one bus can be from 2 to 30 micrometers, preferably from 3 to 20 micrometers, more preferably from 4 to 15 micrometers, even more preferably from 5 to 13 micrometers, more preferably, from 6 to 12 micrometers. The thickness of at least one electrically conductive path in regions adjacent to at least one bus can be,
    at least, 2 micrometers, preferably in fur any less 10 micrometers, more preferably, at least 20 micrometers, still more preferably, in fur any less 30 micrometers, still more preferably, in fur any less 40
    micrometers.
    [00028] When the grid comprises a structure of square or rectangular cells, at least one electrically conductive path can be arranged, either in a first direction (vertical pathways) or in a second direction (horizontal pathways).
    [00029] In some embodiments, the grid may comprise more vertical paths than horizontal ones. A grid arrangement with fewer lanes is advantageous because it increases the transmission of light through the window. It is also advantageous to retain some horizontal pathways, to act as an alternative current path, in case some of the vertical pathways are damaged.
    [00030] The distance between adjacent vertical and / or horizontal routes can be at least 100 micrometers, preferably at least 300 micrometers, more preferably, at least 500 micrometers, even more preferably, at least 1000 micrometers, still more preferably, at least 1500 micrometers, more preferably, at least 2000 micrometers. The increase in
    Petition 870190042607, of 05/06/2019, p. 11/45
    9/18 The distance between the adjacent vertical and / or horizontal pathways increases the open area (that is, the cross-sectional portions of the window, which do not comprise electrically conductive pathways), allowing for a greater transmission of light. To reduce any optical distortion while heating the product, such as brightness distortion, it is preferred to have a minimum spacing of adjacent vertical pathways of approximately 2.0 millimeters (2000 micrometers).
    [00031] The width of at least one electrically conductive pathway can be less than 50 micrometers, preferably less than 25 micrometers, even more preferably, less than 17 micrometers, even more preferably, less than 15 micrometers and, more preferably, less to 13 micrometers. It is beneficial that the width of the roads is smaller in order to improve light transmission.
    [00032] The window may further comprise an additional laminated film between two other layers of a glazing material, wherein the additional film comprises a coating capable of reflecting light, at least partially. Such a film can be beneficial, because many windows, such as some automobile windows, require improved solar control performance to reduce unwanted heat from inside a vehicle. Said coating capable of reflecting light, at least partially, can be metallic.
    [00033] Alternatively, the film connected to a grid of at least one electrically conductive path may further comprise, on an opposite surface, a coating capable of reflecting light, at least partially. This arrangement is advantageous because it reduces the complexity of mounting the window. Alternatively, or in addition, a coating
    Petition 870190042607, of 05/06/2019, p. 12/45
    10/18 capable of reflecting light, at least partially, can be located on the same surface of the film, which is connected to the grid.
    [00034] The grid may comprise one or more openings in one or more of the electrically conductive pathways. Sections of the grid can be eliminated by suitable methods, such as mechanical abrasion, laser suppression and / or chemical deletion. Such modification of the grid design can be advantageous, in order to allow, for example, the functionality of the separate circuit tailored for wiper defrosters, windows with heated chambers, and to avoid electromagnetic inference for certain devices, such as toll sensors and rain sensors. Alternatively, the grid can be manufactured as new, with sections excluded to avoid the need for a process of elimination. The window can also comprise one or more of a cleaner defroster, a window with a heated chamber, a toll sensor and a rain sensor.
    [00035] In accordance with another aspect of the present invention, there is provided a method of manufacturing an electrically heated window, comprising:
    [00036] lamination of at least one layer of an interlayer material and a grid of at least one electrically conductive path connected to a film between at least two layers of a glazing material, and [00037] provision an electrical connection means to supply current to the grid, in order to heat the window.
    [00038] According to another aspect of the present invention, the use of an electrically heated window, according to the invention, in a vehicle, such as a car, van, truck, bus, wagon, locomotive, plane, boat, is provided or ship.

    11/18 [00039] In accordance with another aspect of the present invention, a vehicle is provided incorporating at least one electrically heated window according to the invention.
    [00040] It will be appreciated that optional features applicable to an aspect of the invention can be used in any combination, and in any number. In addition, they can also be used with any of the other aspects of the invention in any combination and in any number. This includes, but is not limited to, the claims dependent on any claim to be used as the dependent claims for any other claim in the claims of this Order.

    Petition 870190042607, of 05/06/2019, p. 15/45
    13/18 [00042] Figure 1 is a schematic plan view of a heated window with wire, in accordance with the prior art. The heated window with wire 1 is generally trapezoidal in shape, and comprises a network of narrowly spaced thin wires 2, of which only a small proportion is shown for clarity. The wire network 2 is bounded by a first electrical connection means or bus 3 and a second electrical connection means or bus 4. The wires within the network 2 extend between the first and second electrical connection means 3, 4. These electrical connection means 3, 4 connect the network to an electrical supply (not shown) by means of connectors 5, 6, 7, 8, which can be plug connectors or other connectors known in the art. A dotted line 9 represents the extension, where the periphery of the window is covered by an obscuration band. An obscuration band is usually provided by a black printed ceramic ink, positioned on an interior window surface. The function of the obscuration band is twofold: first, aesthetics, since it acts to hide the window edge and cover the adhesive used to join the window in a vehicle, as well as the frame surrounding the window opening; and, secondly, it prevents the degradation of the adhesive used to attach the window to the vehicle, due to exposure to UV rays from sunlight.
    [00043] A wireless area 10 is represented by a dashed region, and, in this example, is positioned adjacent to the top edge of window 1 (when placed on a vehicle). A bus 3 is shaped to define the wireless area, to allow a data signal to be transmitted through the window to a device located in the vicinity of the area
    Petition 870190042607, of 05/06/2019, p. 16/45
    14/18 wireless. Ideally, wireless area 10 is covered by the obscuration band. In addition, window 1 is provided with an area for the position of a mirror ledge, and an area 12 for the position of a sensor, such as a light or humidity sensor.
    [00044] Figure 2 is a schematic cross section of a lateral marginal zone of the heated window with wire shown in Figure 1. Window 1 comprises first 13 and second 14 layers of silicate annealed float glass having a layer of polyvinyl interlayer butyral 15, extended and laminated between them. The obscuration band 16 is provided around the periphery of the window 1, obscuring one of the busbars 3. On the side of the window 1, the wires in the network 2 are parallel to the edge of the window 1.
    [00045] Figure 3 is a schematic plan view of the window in Figure 1, showing the bus separations. In Figure 3, only busbars 3, 4 and the general window format are shown for clarity. Bus 3, which runs along the top edge of window 1, adjacent to wireless region 10, is shaped to define the wireless region, with multiple turns or corners. In this example, bus 3, which runs along the top edge of window 1, is divided into two portions, separated by a small gap positioned on an approximate mirror symmetry line, vertically in the center of window 1.
    [00046] The spacing between bus 3, which runs along the top edge of window 1, and conductive bus 4, which runs along the bottom edge of window in a marginal region of window 1 (which would be adjacent to pillar A , when mounted on a vehicle), is represented by the distance X. The
    Petition 870190042607, of 05/06/2019, p. 17/45
    15/18 spacing between bus 3, which runs along the top edge of window 1, and conductive bus 4, which runs along the bottom edge of the window in the center, adjacent to wireless area 10, is represented by the Y spacing Typically, the Y spacing in the center of window 1 is 10% greater than the X spacing at the edge of window 1 adjacent to pillar A. This leads to a region having the same width as the wireless area having an increased temperature, compared to the rest of the window, due to the decrease in resistance and consequent increase in the current carried in the shorter wires. As the wireless area can be up to 300 mm wide, this hot spot region can also be at least 300 mm wide.
    [00047] Figure 4 shows a schematic cross section of an electrically heated window 20, according to an embodiment of the present invention. This embodiment solves the problem of hot spots, through the use of a silver grid 21, which prevents variation in the resistance of individual pathways, minimizing the occurrence of hot spots. The silver grid acts effectively as a conductive sheet, in which the current does not necessarily flow perpendicular to the busbars. The grid can be modified (by excluding small sections manually by abrasion, laser deletion, etc.), to avoid the localized formation of hot spots. As with the prior art window mentioned above, the window 20 is generally trapezoidal in shape (not shown), having two long opposite edges and two shorter opposite edges. The grid 21 is attached to a PET film 22, and is connected to two tinned copper busbars 23, 24. The grid 21, PET film 22 and
    Petition 870190042607, of 05/06/2019, p. 18/45
    16/18 busbars 23, 24 are laminated between two layers of transparent glass 25, 26, using a PVB interlayer 27. Buses 23, 24 are connected directly to the PVB interlayer 27, to contact grid 21, or can be connected directly to the grid itself (by means of welding or a conductive adhesive).
    [00048] Figure 5 shows a schematic plan view of the electrically heated window 20 shown in Figure 4. The Figure shows the generally trapezoidal shape of window 20, together with a small proportion of the silver grid 21 for clarity. The grid 21 tracks are 6 to 12 micrometers thick and about 16 micrometers wide. The distance between adjacent vertical and / or horizontal adjacent routes is 280 micrometers. The PET film 22 has a thickness of 100 micrometers. Busbars 23, 24 are 3 to millimeters wide and 0.03 to 0.08 millimeters thick, with the tinned surface comprising elemental Sn, or an alloy having a Sn: Pb ratio of 60:40. The bars 23, 24 can be of a single piece of sheet, or they can be formed of several pieces of sheet, superimposed on the paths of grid 21, partially pressed between them. Typically, the PVB 27 interlayer material layer is 0.76 mm thick (two portions of each, 0.38 mm thick), and the glass layers are in the range of 1.2 to 3.0 millimeters thick.
    [00049] Although the invention is described in terms of silicate annealed float glass, other types of glass or glazing materials, such as polycarbonate or plastics, can be used in place of these layers of glass.
    [00050] Buses 23, 24 connect grid 21 to an electrical supply (not shown) by means of connectors, which
    Petition 870190042607, of 05/06/2019, p. 19/45
    17/18 may be plug connectors, or other connectors known in the art. An obscuration band can be provided by a black printed ceramic ink, positioned on an interior window surface.
    [00051] For good defrosting performance, it is generally desirable to ensure a uniform power density of 500600 W / m 2 across the window. For defogging, lower power densities (400 W / m 2) are acceptable. Higher power densities (2000 W / m 2) can be used for quick defrosting of the wiper blade area.
    [00052] Figure 6 shows a schematic plan view of a silver grid attached to a PET film, highlighting grid dimensions. In this particular grid, the distance between adjacent vertical and horizontal roads is 280 micrometers.
    [00053] Figures 7 and 8 each show a schematic plan view of a silver grid connected to a PET film, where the width of the grid path is 16 micrometers and 12 micrometers, respectively.
    [00054] Figure 9 shows a schematic view of a cross section of a path of a silver grid 21 connected to a PET film 22. As can be seen in this case, the cross section of path 21 is not symmetrical and, generally , the shape of the cross-section of the tracks can be of any suitable shape, which allows current to flow through the tracks.
    [00055] Figure 10 shows a schematic plan view of an unmodified grid 21 (on the left) and a grid 21 with a high surface area of track in a particular region 28 (on the right). As indicated above, a grid 21 with a high surface area of track in a region adjacent to a bus improves the electrical and mechanical interface between the grid and the
    Petition 870190042607, of 05/06/2019, p. 20/45
    18/18 bus.
    [00056] Figure 11 shows a schematic sectional view of the tracks of a grid connected to a PET film 22 with the unmodified tracks 29 (on the left) and some tracks with increased thickness 30 (on the right). As detailed above, increasing the track thickness (the height above the PET surface) in a bus interface area improves the interface between the grid and the bus, and improves weldability.
    [00057] Figure 12 shows a schematic plan view, from the left end, of an unmodified grid 31, a grid with reduced numbers of horizontal tracks 32, a grid with reduced track width 33 and a grid with horizontal width reduced track 34. As indicated above, the reduction
    of the number in ways individual and / or width via is beneficial, because she improves light transmission through gives window. [00058] Figure 13 shows a schematic plan view in a grid 21 with openings 35 in some of the ways s, what is advantageous in some embodiments, for example to allow The
    separate circuit functionality for windows with heated chambers, toll sensors, etc. In the same way, Figure 14 shows a schematic plan view of a grid 21 with openings 36 in some of the roads, in order to allow a circuit in the area of heated wiper rest 37.
    [00059] Figure 15 shows a perspective view of a vehicle 38, according to an embodiment of the invention. The vehicle 38 incorporates an electrically heated window 39 according to the invention.
