Description

[Technical Field]

[0001] The present disclosure relates to a vehicle glazing system with a flat harness. [Background technology]

[0002] Conventionally, there has been a power supply device for an automobile that is characterized by including a single-wire, plate-like metal wiring that is supplied with power from a battery and extends along the vehicle body, and a plurality of wire harnesses that have one end electrically connected to the metal wiring and supply power from the metal wiring to electrical devices installed in the vehicle body (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2016-235089 Summary of the Invention [Problem to be solved by the invention]

[0004] Automobiles are increasingly equipped with electrical equipment that can simultaneously send and receive multiple signals, such as on-board antennas, cameras, and rearview monitors, in addition to power supplies. To supply signals and power to these electrical equipment, flat harnesses are used that can also be used as parallel interfaces to simultaneously send multiple signals. However, as the number of electrical equipment installed in vehicles has tended to increase in recent years, there is a shortage of space for installing flat harnesses, which can make routing the flat harnesses difficult.

[0005] In addition, in recent years, in order to improve the sense of openness inside the vehicle cabin, the area occupied by glass sheets has increased due to larger windshields and the installation of roof glass, etc., which tends to make it even more difficult to route flat harnesses.

[0006] Therefore, an object of the present invention is to provide a vehicle window glass system with a flat harness that can provide a location for arranging the flat harness. [Means for solving the problem]

[0007] A vehicle window glass system with a flat harness according to an embodiment of the present disclosure includes: a first vehicle window glass having a main surface facing the outside of the vehicle cabin and a main surface facing the inside of the vehicle cabin; a first flat harness having a first end, a second end, and a first intermediate extension portion between the first end and the second end, wherein the first intermediate extension portion is fixed to the main surface facing the inside of the vehicle cabin of the first vehicle window glass; a second vehicle window glass having a main surface facing the outside of the vehicle cabin and a main surface facing the inside of the vehicle cabin; and a second flat harness having a third end, a fourth end, and a second intermediate extension portion between the third end and the fourth end, wherein the second intermediate extension portion is fixed to the main surface facing the inside of the vehicle cabin of the second vehicle window glass and the third end is connected to the second end. [Effects of the Invention]

[0008] A vehicle window glass system with a flat harness can be provided, which can provide a location for arranging the flat harness. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0010] Hereinafter, an embodiment of the vehicle window glass system with a flat harness according to the present disclosure will be described. In the following, the same elements will be denoted by the same reference numerals, and duplicated descriptions may be omitted.

[0011] In the following description, an XYZ coordinate system is defined. The direction parallel to the X axis (X direction), the direction parallel to the Y axis (Y direction), and the direction parallel to the Z axis (Z direction) are perpendicular to one another. For ease of explanation, the -Z direction may be referred to as the lower side or bottom, and the +Z direction may be referred to as the upper side or top, but this does not indicate a universal vertical relationship. Planar view refers to a view from the XY plane. In the following description, the length, width, thickness, etc. of each part may be exaggerated to make the configuration easier to understand. Terms such as parallel, right angle, orthogonal, horizontal, vertical, top and bottom, etc., are intended to allow for deviations that do not impair the effects of the embodiments.

[0012] The vehicle window glass system with a flat harness in this embodiment can be used for roof glass attached to the ceiling of a vehicle, windshields (windshields) attached to the front of a vehicle, fixed side glass (including front bench glass and rear quarter glass) attached to the side of a vehicle, rear glass attached to the rear of a vehicle, etc.

[0013] The vehicle may be, for example, an automobile such as an EV (Electric Vehicle), a PHEV (Plug-in Hybrid Electric Vehicle), a HV (Hybrid Vehicle), a gasoline-powered vehicle, or a diesel-powered vehicle. The vehicle may also be a train or steam locomotive. A vehicle is an example of a moving body that transports passengers.

[0014] In the following description, the term "outside the vehicle cabin" refers to the outside of the vehicle (outside the cabin), and the term "inside the vehicle cabin" refers to the inside of the vehicle (inside the cabin). In the following description, the terms "left" and "right" are used to refer to the left and right directions in the direction of travel of the vehicle.

[0015] <Embodiment> 1A is a diagram showing an example of the configuration of a vehicle 1 equipped with a vehicle window glass system 200 with a flat harness according to an embodiment. The vehicle window glass system 200 with a flat harness includes a plurality of vehicle window glasses 100 with flat harnesses.

[0016] The vehicle 1 includes a vehicle body 10 and a vehicle window glass system with a flat harness 200. The vehicle 1 is, for example, an automobile such as an EV (Electric Vehicle), a PHEV (Plug-in Hybrid Electric Vehicle), an HV (Hybrid Vehicle), a gasoline vehicle, or a diesel vehicle. The vehicle may also be a train or steam locomotive.

[0017] <Body 10> The vehicle body 10 has an opening 11RF for a roof glass, openings 11SD provided on the left and right sides, an opening 11WS for a windshield (front window), and an opening 11BL for a rear glass. The vehicle window glass system 200 with a flat harness mounted on the vehicle 1 shown in Fig. 1A includes, as an example, two vehicle window glasses 100 with a flat harness used as a windshield and a roof glass.

[0018] The plurality of vehicle window glasses 100 with flat harnesses included in the vehicle window glass system 200 with flat harnesses is not limited to two vehicle window glasses 100 with flat harnesses used as a windshield and a roof glass. The plurality of vehicle window glasses 100 with flat harnesses included in the vehicle window glass system 200 with flat harnesses may be two vehicle window glasses 100 with flat harnesses used as a roof glass and a rear glass, three vehicle window glasses 100 with flat harnesses used as a windshield, a roof glass, and a rear glass, or any other combination thereof. Here, a vehicle window glass system 200 with flat harnesses including two vehicle window glasses 100 with flat harnesses used as a windshield and a roof glass will be described using FIG. 1B in addition to FIG. 1A.

[0019] Fig. 1B is a plan view showing an example of the arrangement of the windshield (WS), roof glass (RF), and rear glass (BL) of the vehicle 1 shown in Fig. 1A. Fig. 1B shows the windshield (WS), roof glass (RF), and rear glass (BL) in plan view, in that order from top to bottom. In Fig. 1B, the upper side corresponds to the front of the vehicle 1, the lower side corresponds to the rear of the vehicle 1, the left side corresponds to the left side of the vehicle 1, and the right side corresponds to the right side of the vehicle 1.

[0020] The vehicle 1 shown in FIG. 1B includes a vehicle window glass 100A1 with a flat harness as a windshield and a vehicle window glass 100A2 with a flat harness as a roof glass. The vehicle window glasses 100A1 and 100A2 with a flat harness may actually be three-dimensionally curved or may have different widths in the left-right direction than in the front-to-rear direction, but FIG. 1B shows the vehicle window glasses 100A1 and 100A2 with a flat harness in a simplified form. Also, FIG. 1B shows the rear glass in a simplified form as a rectangular frame. The vehicle window glasses 100A1 and 100A2 with a flat harness constitute a vehicle window glass system 200.

[0021] A vehicle window glass 100A1 with a flat harness used as a windshield includes a laminated glass 110 and a flat harness 120, as shown in FIG. 1B.

[0022] The rectangular annular ceramic layer 114 of the vehicle window glass 100A1 with a flat windshield harness is provided on the interior-facing main surface of the exterior glass sheet along the outer edge of the laminated glass 110, and has a rectangular annular shape in plan view. The ceramic layer 114 has a protrusion 114A in the center of the rear end in the left-right direction to conceal the periphery of a camera that captures images of the front. The rear end of the windshield is located higher than the front end in the up-down direction, and is therefore the upper end of the windshield.

[0023] As an example, the flat harness 120 is disposed between the two glass sheets of the laminated glass 110 and extends along the outer edge of the right end of the laminated glass 110. The flat harness 120 is hidden from view from the outside of the room by the ceramic layer 114. Note that detailed configurations of the laminated glass 110 and the flat harness 120 will be described later using Figures 2A to 2K and 3A to 3L, and will only be briefly described here.

[0024] The vehicle window glass 100A2 with a flat harness used as roof glass includes, for example, a laminated glass 110, a flat harness 120, and a functional member 140. A rectangular annular ceramic layer 114 is provided on the outer edge of the laminated glass 110 of the vehicle window glass 100A2 with a flat harness, and the functional member 140, which is rectangular in plan view, is surrounded by the ceramic layer 114. Note that the vehicle window glass 100A2 with a flat harness used as roof glass may be configured to include a single sheet of glass instead of the laminated glass 110.

[0025] The front end (one end) of the flat harness 120 of the vehicle window glass 100A2 with flat harness is connected to the rear end of the flat harness 120 of the vehicle window glass 100A1 with flat harness, and the other end is connected to the functional member 140 arranged on the vehicle window glass 100A2 with flat harness.

[0026] In such a vehicle window glass system 200 with a flat harness, if the front end of the flat harness 120 of the vehicle window glass 100A1 with a flat harness for the windshield is connected to the power source, ECU, etc. of the vehicle 1, signals, power, etc. can be transmitted between the power source, ECU, etc. and the functional component 140 via the flat harness 120 of the vehicle window glasses 100A1 and 100A2 with flat harnesses.

[0027] <Configuration of the vehicle window glass 100 with flat harness> 2A is a diagram showing an example of a cross-sectional configuration of a vehicle window glass 100 with a flat harness. FIG. 2A shows a flange 11A provided at an opening 11WS of a vehicle body 10. The flange 11A is also provided at openings 11RF and 11BL. The flange 11A may also be provided at opening 11SD. The vehicle window glass 100 with a flat harness includes a laminated glass 110 and a flat harness 120.

[0028] 2A, the XYZ coordinates are defined based on the main surface of the laminated glass 110. The direction parallel to the X axis (X direction), the direction parallel to the Y axis (Y direction), and the direction parallel to the Z axis (Z direction) are perpendicular to one another. The +Z direction side is the exterior side of the vehicle body 10. The Z axis extends in the normal direction of the laminated glass 110. In the following, a planar view refers to viewing an object in an XY plane in the direction in which the Z axis extends.

[0029] Here, as an example, a case will be described in which the vehicle window glass 100 with a flat harness is used as a windshield. Therefore, when the vehicle window glass 100 with a flat harness is attached to the opening 11WS of the vehicle 1, the -X direction side is the front and lower side, and the +X direction side is the rear and upper side with respect to the traveling direction of the vehicle 1. Furthermore, the -Y direction side is the left side of the vehicle 1, and the +Y direction side is the right side of the vehicle 1.

[0030] <Laminated Glass 110> The laminated glass 110 includes glass plates 111 and 112, an interlayer film 113, and a ceramic layer 114 (an example of a shielding layer). The glass plate 111 is an example of a first glass plate, and the glass plate 112 is an example of a second glass plate. The laminated glass 110 has a four-sided rectangular shape in a plan view. The laminated glass 110 is fixed to a flange 11A by an adhesive 20. As an example, the adhesive 20 is provided on a main surface 112B of a glass plate 112 of the laminated glass 110 in a plan view, along the outer edge of the laminated glass 110 in a plan view, over the entire circumference of the outer edge. However, the adhesive 20 may be interrupted in a partial section around the outer edge of the laminated glass 110 in a plan view.

[0031] The laminated glass 110 is formed by bonding a glass plate 111 arranged on the exterior side of the vehicle body 10 to a glass plate 112 arranged on the interior side of the vehicle body 10 via an intermediate film 113 arranged between the glass plates 111 and 112.

[0032] <Glass plates 111 and 112> The glass plates 111 and 112 are transparent, flat glass plates. The glass plate 111 has an outdoor-side main surface 111A and an indoor-side main surface 111B. The main surface 111A is an example of a first main surface, and the indoor-side main surface 111B is an example of a second main surface. The glass plate 112 has an outdoor-side main surface 112A and an indoor-side main surface 112B. The main surface 112A is an example of a third main surface, and the indoor-side main surface 112B is an example of a fourth main surface. The main surfaces 111B and 112B are examples of indoor-side main surfaces.

[0033] The glass plates 111 and 112 may be inorganic glass or organic glass. Examples of inorganic glass that can be used without particular limitation include soda-lime glass, aluminosilicate glass, borosilicate glass, alkali-free glass, and quartz glass. Among these, soda-lime glass is particularly preferred from the viewpoints of manufacturing cost and formability. The forming method of the glass plates 111 and 112 is not particularly limited. For example, in the case of inorganic glass, glass plates formed by a float method or the like are preferred.

[0034] When the glass plates 111 and 112 are inorganic glass, they may be either untempered glass or tempered glass. Untempered glass is produced by forming molten glass into a plate shape and slowly cooling it. Tempered glass is produced by forming a compressive stress layer on the surface of untempered glass, and may be either air-cooled tempered glass or chemically tempered glass.

[0035] If the tempered glass is physically tempered glass (e.g., air-cooled tempered glass), the glass surface may be tempered by a process other than slow cooling, such as rapidly cooling a uniformly heated glass sheet from a temperature near its softening point during bending, thereby generating a compressive stress layer on the glass surface due to the temperature difference between the glass surface and the interior of the glass. If the tempered glass is chemically tempered glass, the glass surface may be tempered after bending by generating compressive stress on the glass surface using an ion exchange method or the like. Glass that absorbs ultraviolet or infrared rays may also be used for the glass sheets 111 and 112. The glass sheets 111 and 112 are preferably transparent, but may also be colored to the extent that transparency is not impaired. The glass sheets 111 and 112 do not have to be transparent.

[0036] The laminated glass 110 may have a curved shape such that the exterior side is convex when attached to the vehicle body 10. The laminated glass 110 may have a single-curve shape bent in only one direction, or may have a compound-curve shape bent in two directions (for example, the vertical direction when the laminated glass 110 is attached to the vehicle body 10 and the horizontal direction perpendicular to the vertical direction). Gravity forming, press forming, roller forming, or the like is used to bend the laminated glass 110. When the laminated glass 110 is bent to a predetermined curvature, the radius of curvature of the laminated glass 110 may be 1,000 mm or more and 100,000 mm or less.

[0037] Furthermore, when the laminated glass 110 is attached to the vehicle body 10, the thickness of the glass plate 111 located on the exterior side and the thickness of the glass plate 112 located on the interior side may be the same or different. The thickness of the glass plate 111 is preferably 1.0 mm or more and 3.0 mm or less. A thickness of 1.0 mm or more of the glass plate 111 provides sufficient strength, such as resistance to flying stones, while a thickness of 3.0 mm or less prevents the laminated glass 110 from becoming too heavy, which is preferable in terms of fuel efficiency of the vehicle. The thickness of the glass plate 112 is preferably 0.3 mm or more and 2.3 mm or less. A thickness of 0.3 mm or more of the glass plate 112 provides good handling, while a thickness of 2.3 mm or less prevents the laminated glass 110 from becoming too heavy. The thicknesses of the glass plates 111 and 112 are preferably 1.8 mm or less, which allows the laminated glass 110 to achieve both lightweight and sound insulation, respectively. Note that when the thickness of the glass plate 112 is 1.0 mm or less, the glass plate 112 may be chemically strengthened glass. When the glass plate 112 is a chemically strengthened glass, it is preferable that the compressive stress value of the glass surface is 300 MPa or more, and the depth of the compressive stress layer is 2 μm or more.

[0038] When the glass plates 111 and 112 are made of organic glass, examples of the material for the organic glass include transparent resins such as polycarbonate and acrylic resins (for example, polymethyl methacrylate).

[0039] When single-pane glass is used instead of the laminated glass 110, the single-pane glass is preferably tempered glass, for example. Physically tempered glass (for example, air-cooled tempered glass) can be used as tempered glass. When single-pane glass is used, the thickness of the glass plate is preferably 2.0 mm or more and 5.0 mm or less. If the thickness of the glass plate is 2.0 mm or more, the strength for resistance to flying stones and the like is sufficient, and if it is 5.0 mm or less, the mass of the glass plate is not too large, which is preferable in terms of fuel efficiency of the vehicle.

[0040] <Interlayer film 113> The interlayer 113 is a transparent or semi-transparent dielectric material having dielectric properties and interposed between the glass plates 111 and 112. The glass plates 111 and 112 are bonded together by the interlayer 113. The interlayer 113 has, for example, a two-layer structure. In the area where the flat harness 120 is present, a first layer is provided between the glass plate 111 and the flat harness 120, and a second layer is provided between the flat harness 120 and the glass plate 112. In the area where the flat harness 120 is not present, the first and second layers of the interlayer 113 are directly stacked. Note that, when a Low-E film is formed on the main surface 111B of the glass plate 111, the interlayer 113 may bond between the Low-E film and the glass plate 112. Examples of materials for the interlayer 113 include thermoplastic polyvinyl butyral (PVB) and ethylene vinyl acetate copolymer (EVA). The interlayer 113 may be transparent or colored. Furthermore, the intermediate film 113 may be composed of two or more layers of film. As an example, when a Low-E film is formed on the main surface 111B of the glass plate 111 and the ceramic layer 114 is formed on a part of the surface on the -Z direction side of the Low-E film, the intermediate film 113 is disposed between the ceramic layer 114 and the glass plate 112 in the portion where the ceramic layer 114 exists in plan view.

[0041] <Ceramic layer 114> The ceramic layer 114 is, for example, a fired product of a dark ceramic paste, and is formed by applying and firing a ceramic color paste containing a fusible glass frit containing a black pigment. The ceramic layer 114 is formed to prevent deterioration of the adhesive caused by ultraviolet rays when the vehicle window glass 100 with a flat harness is adhered to the vehicle body 10, and to improve the appearance by preventing the connection portion between the vehicle window glass 100 with a flat harness and the vehicle body 10, the flat harness 120, etc. from being seen from the outside of the vehicle body 10. The flat harness 120 is positioned so as to overlap with the ceramic layer 114 in a plan view.

[0042] For example, the ceramic layer 114 is provided on the indoor-side main surface 111B of the glass plate 111. Note that, when a Low-E film is formed on the main surface 111B of the glass plate 111, the ceramic layer 114 may be provided on the indoor-side main surface 111B of the glass plate 111 via the Low-E film. Note that, for example, the ceramic layer 114 may be provided on the indoor-side main surface 111B of the glass plate 111. In this case, the Low-E film is provided on the indoor-side main surface 111B of the glass plate 111 in areas where the ceramic layer 114 is not present, and the Low-E film may not be present in areas where the ceramic layer 114 is present. Note that the ceramic layer 114 may be provided in layers on each of the indoor-side main surfaces 111B and 112B of the glass plates 111 and 112, or may be provided only on the indoor-side main surface 112B of the glass plate 112. Furthermore, the ceramic layer 114 may be provided on the main surface 112A of the glass plate 112 instead of the main surface 111B or 112B. The ceramic layer 114 may be provided only on the main surface 112A of the glass plate 112. When a single-pane glass is used instead of the laminated glass 110, the ceramic layer 114 is provided on the main surface of the single-pane glass facing the interior.

[0043] As an example, the ceramic layer 114 is provided on the peripheral portion of the main surface 111B of the laminated glass 110 in a plan view. The peripheral portion of the laminated glass 110 is a peripheral portion of the laminated glass 110 that is slightly inside the outer edge of the laminated glass 110 in a plan view and follows the outer edge. The peripheral portion of the laminated glass 110 is the peripheral portions of the glass sheets 111 and 112, and the outer edge of the laminated glass 110 is the outer edges of the glass sheets 111 and 112.

[0044] As described above, a Low-E film may be formed on the main surface 111B (second main surface) of the glass plate 111. The Low-E film is a film that reflects far-infrared rays and is provided to improve the heat insulating or heat-shielding performance of the laminated glass 110. For example, the Low-E film is produced by forming (coating) a transparent conductive film made of tin oxide, silver, ITO, or the like on the main surface 112B of the glass plate 112. Note that the Low-E film may also be a conductive film other than a transparent conductive film made of tin oxide, silver, ITO, or the like. Alternatively, instead of the Low-E film, a heat ray reflective film in which metal layers and oxide layers are alternately laminated may be used. Note that a Low-E film may also be formed on the main surface 112B (fourth main surface) of the glass plate 112. As an example, a thermal reflective film may be formed on the main surface 111B (second main surface) of the glass plate 111, and a Low-E film may be formed on the main surface 112B (fourth main surface) of the glass plate 112. When a single-pane glass is used instead of the laminated glass 110, the Low-E film is provided on the main surface of the single-pane glass facing the interior.

[0045] <Flat harness 120> The flat harness 120 is a foil-shaped connecting member in which a linear foil conductor 120-1 is covered with an insulating layer 120-2. The foil conductor 120-1 is made of, for example, copper foil or aluminum foil. The insulating layer 120-2 is made of, for example, vinyl chloride or cross-linked polyethylene. Examples of the flat harness 120 include an FPC (Flexible Printed Cable), an FFC (Flexible Flat Cable), and a ribbon cable.

[0046] The foil conductor 120-1 can be used as a signal transmission line for transmitting signals or a power transmission line for transmitting power. The flat harness 120 needs to have at least one foil conductor 120-1, and may have multiple foil conductors 120-1. When the flat harness 120 has multiple foil conductors 120-1, the multiple foil conductors 120-1 only need to be insulated from each other by the insulating layer 120-2. Note that the cross-sectional structure of the flat harness 120 is not limited to a three-layer structure of the insulating layer 120-2, the foil conductor 120-1, and the insulating layer 120-2. It may be a single-layer structure (such as copper foil) consisting of only foil-shaped conductor 120-1, a two-layer structure consisting of foil-shaped conductor 120-1 and insulating layer 120-2, a four-layer structure consisting of insulating layer 120-2, foil-shaped conductor 120-1, insulating layer 120-2, foil-shaped conductor 120-1 and insulating layer 120-2, or a five-layer structure consisting of foil-shaped conductor 120-1, insulating layer 120-2, foil-shaped conductor 120-1 and insulating layer 120-2.

[0047] The flat harness 120 has an end portion 121, an end portion 122, and an intermediate extending portion 123. The end portion 121 and the end portion 122 are portions at both ends of the flat harness 120. The intermediate extending portion 123 is a portion extending in the X direction between the end portion 121 and the end portion 122, and connects the end portion 121 and the end portion 122. That is, the foil conductor 120-1 and the insulating layer 120-2 extend in the X direction between the end portion 121 and the end portion 122.

[0048] End 121 and end 122 have terminals at their tips. End 121 and end 122 can be connected to electrical equipment, a power source, a ground potential point, or the like of vehicle 1. The electrical equipment is an ECU (Electronic Control Unit), air conditioner, heater, audio, navigation device, antenna, computer, or the like. The power source is a battery, generator, or the like mounted on vehicle 1. The ground potential point is vehicle body 10. By connecting end 121 and end 122 to these, flat harness 120 can be used as a signal transmission line or a power transmission line.

[0049] The intermediate extension 123 is located between the glass plates 111 and 112. The end portions 121 and 122 are located outside the glass plates 111 and 112. A ceramic layer 114 is provided on the glass plate 111, and an interlayer film 113 is disposed between the glass plates 111 and 112. The positional relationship between the glass plates 111 and 112, the interlayer film 113, the ceramic layer 114, and the flat harness 120 will be described below.

[0050] As an example, the intermediate extending portion 123 is disposed between the first interlayer film 113 and the second interlayer film 113 of the laminated glass 110. The intermediate extending portion 123 extends in the X direction at a position overlapping with the ceramic layer 114 in a plan view. It is preferable that the flat harness 120 is not visible when the vehicle window glass 100 with a flat harness is viewed from the exterior side. Note that the end portions 121 and 122 may be disposed at positions that are not visible from the exterior side or the interior side when the glass is attached to the vehicle body 10.

[0051] As an example, the flat harness 120 extends parallel to a portion of the inner edge of the opening 11WS that extends in the X direction. While Fig. 2A shows a configuration in which the flat harness 120 extends in the X direction in the XZ cross section, the flat harness 120 may extend in a direction other than the X direction as long as it extends along the inner edge of the opening 11WS. In other words, the flat harness 120 extends along one of the four sides of the outer edge of the laminated glass 110 and is disposed at the end of the laminated glass 110.

[0052] Furthermore, at least a portion of the flat harness 120 may be located in a region of the laminated glass 110 that does not overlap with the ceramic layer 114. For example, it is possible to realize a configuration in which at least a portion of the flat harness 120 is located inside the ceramic layer 114 provided on the peripheral edge of the laminated glass 110.

[0053] A flat harness 120 is placed on the main surface 112A of a glass plate 112 of a laminated glass 110, and an intermediate film 113 is used to bond the flat harness 120 to a glass plate 111 on which a ceramic layer 114 is formed, thereby producing a vehicle window glass 100 with a flat harness.

[0054] Specifically, a second interlayer film 113 is placed on the main surface 112A of the glass sheet 112 of the laminated glass 110, and a temporary laminate is formed by further laminating a flat harness 120, the first interlayer film 113, and a glass sheet 111 on which a ceramic layer 114 has been formed. The temporary laminate is then pre-pressed to form a pre-pressed body. The pre-pressed body is then fully pressed to obtain the laminated glass 110. For example, the pre-pressed body can be placed in a bag made of rubber or the like and heated under reduced pressure at a pressure of approximately −65 kPa to −100 kPa inside the bag (absolute pressure of approximately 36 kPa to 1 kPa) at a temperature of 60°C to 110°C, which is lower than the heating temperature in the subsequent step (S16). The heating temperature is preferably 60°C to 100°C, more preferably 60°C to 90°C. The heating time is preferably 5 to 30 minutes. For example, the pre-compression bonding can be performed by placing the pre-compression bonded body in an autoclave and applying pressure and heat at a pressure of approximately 0.98 MPa to 1.47 MPa and a temperature of 100°C to 150°C. The heating temperature is preferably 110°C to 150°C, more preferably 120°C to 150°C. The heating time is preferably 20 minutes to 40 minutes. The pre-compression bonding may be performed without going through the pre-compression bonding step.

[0055] 2A, the intermediate extending portion 123 is not limited to being disposed between the main surface 112A of the glass plate 112 and the intermediate film 113. FIGS. 2B and 2C are diagrams showing examples of variations in the position of the intermediate extending portion 123.

[0056] The intermediate extension 123 may be disposed so as to contact the ceramic layer 114 formed on the main surface 111B of the glass plate 111 as shown in FIG. 2B.

[0057] Alternatively, the intermediate extending portion 123 may be disposed so as to be in contact with the main surface 112A of the glass plate 112, as shown in FIG. 2C.

[0058] Furthermore, when the vehicle window glass 100 with a flat harness has multiple foil-like conductors 120-1, as an example, some of the foil-like conductors 120-1 may have their intermediate extension portions 123 sandwiched between two layers of intermediate film 113 as shown in Figure 2A, and the remaining foil-like conductors 120-1 may have their intermediate extension portions 123 arranged in contact with the ceramic layer 114 as shown in Figure 2B.

[0059] Furthermore, the vehicle window glass 100 with a flat harness may include a flat harness 120 arranged on the main surface 112B of the glass plate 112, in addition to the flat harness 120 having an intermediate extension portion 123 arranged between the glass plates 111 and 112. The intermediate extension portion 123 of the flat harness 120 arranged on the main surface 112B of the glass plate 112 is preferably arranged at a position overlapping the ceramic layer 114 in a plan view. The flat harness 120 is fixed to the main surface 112B of the glass plate 112 by adhesive, double-sided tape, clips, or the like.

[0060] In addition, the vehicle window glass 100 with a flat harness may be configured to include a flat harness 120 arranged on the main surface 112B of the glass plate 112, without including a flat harness 120 having an intermediate extension portion 123 arranged between the glass plates 111 and 112.

[0061] In addition, when the ceramic layer 114 is arranged on the outdoor main surface 112A of the glass plate 112, the intermediate extension portion 123 may be arranged so as to be in contact with the outdoor main surface 112A of the glass plate 112 and so as to be in contact with the ceramic layer 114.

[0062] Furthermore, when the vehicle window glass with flat harness 100 includes a single sheet of glass instead of the laminated glass 110, the flat harness 120 may be disposed on the interior surface of the ceramic layer 114 formed on the interior main surface of the single sheet of glass. The flat harness 120 is fixed to the interior surface of the ceramic layer 114 by adhesive, double-sided tape, clips, or the like.

[0063] 2D is a diagram showing an example of a variation in the configuration of end portion 121 and end portion 122. In addition, end portion 121 and end portion 122 may be configured as shown in FIG.

[0064] 2D , end 121 and end 122 may be folded back along the side surface and main surface 112B of glass plate 112 on the −X direction side and +X direction side of laminated glass 110, respectively, and passed between main surface 112B and adhesive 20, and routed inward of adhesive 20 in plan view. In this case, the tips of end 121 and end 122 are located on the indoor side of adhesive 20, thereby improving waterproofing and dustproofing properties.

[0065] <100S vehicle window glass with flat harness, including single-pane glass 110S> FIG. 2E is a diagram showing an example of a cross-sectional configuration of a vehicle window glass 100S with a flat harness including a single sheet glass 110S.

[0066] The vehicle window glass 100S with a flat harness includes a single sheet glass 110S and a flat harness 120. The vehicle window glass 100S with a flat harness has a configuration in which the laminated glass 110 of the vehicle window glass 100 with a flat harness shown in Fig. 2A is replaced with the single sheet glass 110S.

[0067] The single-pane glass 110S has a glass plate 111 and a ceramic layer 114. The glass plate 111 has an exterior main surface 111SA and an interior main surface 112SA. The ceramic layer 114 is provided on the interior main surface 112SA. A Low-E film may be formed on the main surface 112SA.

[0068] The flat harness 120 is provided on the interior-facing surface of the ceramic layer 114. In the vehicle window glass 100S with a flat harness shown in Fig. 2E, both end sides of the intermediate extension portion 123 of the flat harness 120 pass between the main surface 112SA and the adhesive 20, and the end portions 121 and 122 are located on the exterior side of the adhesive 20. Note that the vehicle window glass 100S with a flat harness shown in Fig. 2E may be considered to have a configuration in which the portions of the end portions 121 and 122 close to the intermediate extension portion 123 pass between the main surface 112SA and the adhesive 20.

[0069] Fig. 2F is a diagram showing an example of a variation in the configuration of the end portion 121 and the end portion 122 of the vehicle window glass 100S with a flat harness. As shown in Fig. 2F, the flat harness 120 does not have to be passed between the main surface 112SA and the adhesive 20. In Fig. 2F, the end portion 121 and the end portion 122 are spaced apart from the main surface 112SA on the inner side of the adhesive 20 in a plan view.

[0070] In this case, the end 121 and the end 122 are located on the indoor side of the adhesive 20, thereby improving waterproofing and dustproofing properties.

[0071] <Configuration of the end of the ground wire of the flat harness 120> Fig. 2G is a diagram showing an example of the configuration of the end portion of the ground wire of the flat harness 120. Fig. 2G shows an intermediate extension portion 123 arranged between the glass plates 111 and 112 of the laminated glass 110, and an end portion 122 connected to the +X direction side of the intermediate extension portion 123. The end portion 122 and intermediate extension portion 123 shown in Fig. 2G are the end portion 122 and intermediate extension portion 123 of the foil conductor 120-1 that corresponds to the ground wire among the multiple foil conductors 120-1 included in the flat harness 120.

[0072] As an example, when the vehicle window glass 100 with the flat harness is attached to the flange 11A of the vehicle body 10, the end 122 of the ground wire may be brought into contact with the flange 11A of the vehicle body 10 to provide a direct connection.

[0073] 2G, for example, end 122 of the ground wire is formed on the side surface of glass plates 111 and 112 on the +X direction side. For example, such end 122 can be realized by forming copper foil, aluminum foil, or the like by plating or the like on the side surface of glass plates 111 and 112. Note that end 121 of the ground wire can also be configured in a similar manner.

[0074] <Vehicle window glass 100 with flat harness including flat harnesses 120 and 130> Fig. 2H is a diagram showing an example of a cross-sectional configuration of a vehicle window glass 100 with a flat harness, which includes flat harnesses 120 and 130. The vehicle window glass 100 with a flat harness shown in Fig. 2H includes a laminated glass 110 and flat harnesses 120 and 130. The flat harness 120 is an example of a first flat harness, and the flat harness 130 is an example of a third flat harness.

[0075] The flat harness 120 has an end portion 121, an end portion 122, and an intermediate extension portion 123. The end portions 121 and 122 are examples of a first end portion and a second end portion, respectively. The intermediate extension portion 123 is an example of a first intermediate extension portion. The flat harness 120 shown in FIG. 2H differs from the flat harness 120 shown in FIG. 2A in that the end portion 121 does not extend outside the glass plates 111 and 112, but is located between the glass plates 111 and 112.

[0076] The flat harness 130 has an end portion 131, an end portion 132, and an intermediate extension portion 133. The end portions 131 and 132 are examples of a fifth end portion and a sixth end portion, respectively. The intermediate extension portion 133 is an example of a third intermediate extension portion. The flat harness 130 is composed of a foil conductor and an insulating layer, similar to the foil conductor 120-1 and insulating layer 120-2 of the flat harness 120.

[0077] The end 132 and intermediate extension 133 of the flat harness 130 are disposed on the main surface 112B of the glass plate 112. The end 131 is connected to the end of the intermediate extension 133 on the −X direction side, is located outside the laminated glass 110, and is not fixed to the laminated glass 110. The end 132 and intermediate extension 133 of the flat harness 130 are fixed to the main surface 112B of the glass plate 112 by adhesive, double-sided tape, clips, or the like.

[0078] The end portion 131 and the end portion 132 are both ends of the flat harness 130. The intermediate extending portion 133 is a portion that extends in the X direction between the end portion 131 and the end portion 132, and connects the end portion 131 and the end portion 132.

[0079] 2A, the end 131 can be connected to an electrical component, a power source, a ground potential point, or the like of the vehicle 1. Furthermore, the end 132 is disposed at a position overlapping the end 121 of the flat harness 120 in a plan view, and is coupled to the end 121. The coupling of the end 132 to the end 121 means that the end 132 and the end 121 are coupled, and signals, power, and the like to be supplied to the electrical components, etc. of the vehicle 1 can be transmitted between the end 132 and the end 121. This coupling is a capacitive coupling.

[0080] By coupling the end portion 121 and the end portion 132, the flat harnesses 120 and 130 can be used as a signal transmission line or a power transmission line capable of transmitting AC signals or AC power.

[0081] 2H , the end 122 of the flat harness 120 of the vehicle window glass 100 with a flat harness may be provided between the glass plates 111 and 112, similar to the end 121, and a flat harness 130 similar to the one on the −X direction side may be provided on the +X direction side of the flat harness 120. In this case, the flat harness 120 is coupled to the second flat harness 130 on both the −X direction side and the +X direction side.

[0082] <Vehicle window glass 100 with flat harness including functional member 140> FIG. 2I is a diagram showing an example of a cross-sectional configuration of a vehicle window glass 100 with a flat harness including a functional member 140. As shown in FIG.

[0083] The vehicle window glass 100 with a flat harness shown in Fig. 2I has a configuration in which a functional member 140 is added to the vehicle window glass 100 with a flat harness shown in Fig. 2A, and the flat harness 120 is connected to the functional member 140. One example of the functional member 140 is an antenna.

[0084] Here, Figure 2J is used in addition to Figure 2I. Figure 2J is a plan view showing an example of the configuration of the vehicle window glass 100 with a flat harness shown in Figure 2I. Note that Figure 2J does not show the entire vehicle window glass 100 with a flat harness, but shows the outer edge and a portion close to the outer edge on the +Y direction side of the laminated glass 110.

[0085] 2I and 2J has a branch line 124 branching off from the middle of the intermediate extending portion 123. As an example, the branch line 124 is disposed between the glass plates 111 and 112, similar to the intermediate extending portion 123, and more specifically, as an example, is disposed between the main surface 112A of the glass plate 112 and the intermediate film 113. The branch line 124 branches off from the middle of the intermediate extending portion 123 and extends in the −Y direction, for example. A tip end 124A of the branch line 124 is located at a position overlapping the functional member 140 in a plan view.

[0086] As an example, functional member 140 configured as an antenna is fixed to main surface 112B of glass plate 112 by adhesive or the like. As shown in FIG. 2J, functional member 140 is positioned so as to overlap tip portion 124A of branch line 124 in a plan view. Functional member 140 is coupled to tip portion 124A of branch line 124. "Functional member 140 coupled to tip portion 124A" means that functional member 140 and tip portion 124A are coupled, and signals, power, and the like can be transmitted between functional member 140 and tip portion 124A. This coupling is capacitive coupling.

[0087] The vehicle window glass 100 with a flat harness shown in Figure 2I is capable of transmitting signals, power, etc. between the end 121 and end 122 of the flat harness 120, and is also capable of transmitting signals, power, etc. between the end 121 or end 122 and the functional member 140.

[0088] The functional member 140 may be provided between the glass plates 111 and 112, similarly to the intermediate extending portion 123 and the branch line 124, and the branch line 124 may be directly connected to the functional member 140. Direct connection between the branch line 124 and the functional member 140 refers to a physical connection between a terminal portion of the functional member 140 and a portion of the branch line 124 where the insulating layer 120-2 is not present, i.e., a portion where the foil conductor 120-1 is exposed. While an antenna fixed to the main surface 112B of the glass plate 112 by adhesive or the like has been exemplified as the functional member, a heating wire may also be used. The antenna or heating wire may be a member formed of a metal layer of copper, silver, or the like on a film and fixed to the main surface 112B of the glass plate 112 by adhesive or the like, or may be a conductive pattern formed by applying and firing a frit paste containing silver to the main surface 112B of the glass plate 112.

[0089] <Vehicle window glass 100 with flat harness including functional member 140> FIG. 2K is a diagram showing another example of the cross-sectional configuration of the vehicle window glass 100 with a flat harness including the functional member 140. As shown in FIG.

[0090] The vehicle window glass 100 with a flat harness shown in Fig. 2K has a configuration in which an end portion 122 of the vehicle window glass 100 with a flat harness shown in Fig. 2A is positioned between the glass plates 111 and 112, a functional member 140 is provided between the glass plates 111 and 112, and the end portion 122 is connected to the functional member 140. Note that "the end portion 122 is positioned between the glass plates 111 and 112" means that the end portion 122 is positioned inside the outer edges of the glass plates 111 and 112 in a plan view.

[0091] In the vehicle window glass 100 with a flat harness shown in FIG. 2K, the end portion 122, the intermediate extending portion 123, and the functional member 140 are sandwiched between two layers of intermediate film 113, for example.

[0092] The functional member 140 is a dimmer capable of changing the light transmittance, a light such as an LED (Light Emitting Diode), an antenna, or the like.

[0093] <Implementation variations of the vehicle window glass system 200 with flat harness> 3A to 3L, mounting variations of the vehicle window glass system with a flat harness 200 will be described. Figures 3A to 3L show vehicle window glasses 100B1 to 100I2 with a flat harness. Hereinafter, when there is no need to distinguish between the vehicle window glasses with a flat harness 100B1 to 100I2, they will simply be referred to as vehicle window glasses with a flat harness 100.

[0094] The vehicle window glass system 200 with a flat harness may include any plurality of vehicle window glasses 100 with a flat harness among the vehicle window glasses 100B1 to 100I2 with a flat harness shown in Figures 3A to 3L. The plurality of vehicle window glasses 100 with a flat harness may include those of the same type.

[0095] 3A to 3L show the windshield (WS), roof glass (RF), and rear glass (BL) in plan view, from top to bottom. In Figures 3A to 3L, the upper side corresponds to the front of the vehicle 1, the lower side corresponds to the rear of the vehicle 1, the left side corresponds to the left side of the vehicle 1, and the right side corresponds to the right side of the vehicle 1.

[0096] <Vehicle window glass system 200 with flat harness shown in FIG. 3A> The vehicle 1 shown in Fig. 3A includes a vehicle window glass system 200 with a flat harness that is used as a windshield, a vehicle window glass 100B1 with a flat harness that is used as a windshield, and a vehicle window glass 100B2 with a flat harness that is used as a roof glass. The vehicle 1 shown in Fig. 3A also includes a vehicle window glass 50B3 that is used as a rear glass.

[0097] 3B is a diagram showing an example of the cross-sectional configuration of the vehicle window glasses 100B1 and 100B2 with flat harnesses. The vehicle window glasses 100B1 and 100B2 with flat harnesses have the same configuration as the vehicle window glasses 100A1 and 100A2 with flat harnesses shown in FIG. 1B, respectively.

[0098] The laminated glass 110 and the flat harness 120 of one of the vehicle window glasses 100B1 and 100B2 with a flat harness are an example of a first laminated glass and a first flat harness, respectively. The laminated glass 110 and the flat harness 120 of the other of the vehicle window glasses 100B1 and 100B2 with a flat harness are an example of a second laminated glass and a second flat harness, respectively. Furthermore, the other of the vehicle window glasses 100B1 and 100B2 with a flat harness may be regarded as an example of a vehicle window glass.

[0099] The end 121 and the end 122 of the flat harness 120 as an example of the first flat harness are examples of the first end and the second end, respectively. The end 121 and the end 122 of the flat harness 120 as an example of the second flat harness are examples of the third end and the fourth end, respectively.

[0100] The interlayer 113 of the first laminated glass is an example of a first interlayer, and the interlayer 113 of the second laminated glass or vehicle window glass is an example of a second interlayer. The ceramic layer 114 of the first laminated glass is an example of a first shielding layer, and the ceramic layer 114 of the second laminated glass or vehicle window glass is an example of a second shielding layer.

[0101] The relationship between the vehicle window glasses 100B1 and 100B2 with a flat harness and the first and second flat harnesses is the same for the vehicle window glasses 100C1 and 100C2 with a flat harness, which will be described later with reference to Fig. 3C. The same also applies to the vehicle window glasses 100D1 and 100D2, 100F1 and 100F2, 100H1 and 100H2, and 100I1 and 100I2 with a flat harness, which will be described later with reference to Figs. 3D, 3I, 3K, and 3L.

[0102] <Vehicle window glass with flat harness 100B1> The vehicle window glass 100B1 with a flat harness is used as a windshield and does not include the functional member 140, and therefore can be realized, for example, by the vehicle window glass 100 with a flat harness shown in Figures 2A to 2D and 2H. Note that the laminated glass 110 of the vehicle window glass 100B1 with a flat harness has a ceramic layer and a Low-E film, but these are omitted in Figure 3B.

[0103] The flat harness 120 of the vehicle window glass 100B1 with a flat harness used as a windshield has an end portion 121, an end portion 122, and an intermediate extending portion 123. The end portions 121 and 122 are located outside the glass plates 111 and 112. In the vehicle window glass 100B1 with a flat harness, the intermediate extending portion 123 of the flat harness 120 extends between the end portion 121 located at the front end (lower end) on the right side and the end portion 122 located at the rear end (upper end) on the right side. Here, the outer edge of the laminated glass 110 is rectangular, and the laminated glass 110 has four sides. Of the four sides of the laminated glass 110, the side extending front to back on the right side is referred to as the first side, and the side connected to one end side of the first side (for example, the front side) and extending left to right is referred to as the second side. Furthermore, of the four sides of the laminated glass 110, the side that is connected to the other end side of the first side (for example, the rear side) and extends left and right is referred to as the third side, and the side that extends front and rear on the left side is referred to as the fourth side. The first side and the fourth side face each other, and the second side and the third side face each other. In the vehicle window glass 100B1 with a flat harness, the end 121 of the flat harness 120 is located on the second side that is connected to one end side of the first side (for example, the front side), and the end 122 is located on the third side that is connected to the other end side of the first side (for example, the rear side). Furthermore, in FIG. 3A , the flat harness 120 is arranged at the end of the laminated glass 110 along one of the four sides of the laminated glass 110.

[0104] The end 121 of the flat harness 120 of the vehicle window glass 100B1 with the flat harness may be connected to an ECU that controls the functional member 140, a power source, or the like.

[0171] The flat harness 120 of the vehicle window glass with flat harness 100H1 has the same configuration as the flat harness 120 of the vehicle window glass with flat harness 100B1, and is a foil-shaped connecting member in which linear foil conductors 120-1 are covered with an insulating layer 120-2.

[0172] <Functional member 140> The functional member 140 is disposed between the glass plates 111 and 112. The functional member 140 is disposed in the center in the left-right direction at the upper end (rear end) of the laminated glass 110 in a plan view, and is located in a portion overlapping with the ceramic layer 114. One example of the functional member 140 is an antenna.

[0173] <Vehicle window glass with flat harness, 100mm thick> The vehicle window glass 100H2 with a flat harness includes a laminated glass 110, a flat harness 120, and two functional members 140. The vehicle window glass 100H2 with a flat harness has the same structure as the vehicle window glass 100D2 with a flat harness shown in Fig. 3D.

[0174] <Flat harness 120 for vehicle window glass 100H2 with flat harness> Since the flat harness 120 is connected to two functional members 140, the intermediate extension portion 123 connected to the end portion 121 branches into two branch lines and extends to the end portion 122 at the end of each branch line. The two end portions 122 are connected to the terminals of the two functional members 140, respectively.

[0175] The end 121 is connected to an end 122 and a lead-out end 125 of the flat harness 120 of the vehicle window glass 100H1 with the flat harness.

[0176] <Functional member 140> As an example, the functional members 140 are arranged one on each side along the outer edges of the laminated glass 110. Each functional member 140 extends in the front-to-rear direction and is arranged between the glass plates 111 and 112 of the laminated glass 110. As an example, the functional members 140 are dimmers that can change the light transmittance of the laminated glass 110, or lighting such as LEDs.

[0177] <Pull-out end 125> One end of the lead-out end 125 is connected to an end 122 of the flat harness 120 of the vehicle window glass 100H1 with a flat harness and an end 121 of the flat harness 120 of the vehicle window glass 100H2 with a flat harness. The other end of the lead-out end 125 may be connected to an ECU that controls the functional member 140, a power source, or the like.

[0178] <Vehicle window glass 50H3> The vehicle window glass 50H3 used as a rear window is, for example, the same as the vehicle window glass 50B3 shown in FIG. 3A.

[0179] <Summary of Figure 3K> The vehicle window glass system 200 with flat harness shown in Figure 3K can transmit control signals and power between the ECU, power supply, etc. and three functional components 140 via two flat harnesses 120 arranged on the laminated glass 110 of the vehicle window glasses 100H1 and 100H2 with flat harnesses and the pull-out end 125.

The vehicle window glass system 200 with a flat harness shown in Fig. 3L also includes a lead-out end portion 125. The vehicle 1 shown in Fig. 3L also includes a vehicle window glass 50I3 as a rear glass.

[0181] <Vehicle window glass with flat harness 100I1> The vehicle window glass 100I1 with a flat harness includes a laminated glass 110, a flat harness 120, and two functional members 140. Similar to the laminated glass 110 of the vehicle window glass 100B1 with a flat harness shown in Fig. 3A, the laminated glass 110 has glass plates 111 and 112 and an interlayer film 113. The laminated glass 110 of the vehicle window glass 100I1 with a flat harness also has a ceramic layer and a Low-E film, which are omitted in Fig. 3L.

[0182] The vehicle window glass 100I1 with a flat harness has two functional members 140, which are the same as the vehicle window glass 100H1 with a flat harness shown in Fig. 3K, and the intermediate extending portion 123 of the flat harness 120 is branched to connect the two end portions 121 to the two functional members 140. As an example, the added functional member 140 is arranged between the glass plates 111 and 112, and is arranged in the center in the left-right direction of the lower end (front end) of the laminated glass 110 in a plan view, and is located in the portion overlapping with the ceramic layer 114.

[0183] <Flat harness 120 for vehicle window glass 100I1 with flat harness> The flat harness 120 of the vehicle window glass 100I1 with a flat harness has two end portions 121, an end portion 122, and an intermediate extension portion 123. The two end portions 121 and the end portion 122 are three end portions of the flat harness 120 having the branched intermediate extension portion 123.

[0184] The two end portions 121 are located between the glass plates 111 and 112 together with the two functional members 140. One end portion 121 is located at the upper end (rear end) of the right side of the laminated glass 110 in a plan view, and is connected to the right end of the functional member 140 that is located in the center in the left-right direction of the upper end (rear end) of the laminated glass 110 in a plan view. The other end portion 121 is located at the lower end (front end) of the right side of the laminated glass 110 in a plan view, and is connected to the right end of the functional member 140 that is located in the center in the left-right direction of the lower end (front end) of the laminated glass 110 in a plan view.

[0185] The end portion 122 is located outside the glass plates 111 and 112. The end portion 122 is connected to the end portion 121 and the lead-out end portion 125 of the flat harness 120 of the vehicle window glass 100I2 with a flat harness.

[0186] The intermediate extension portion 123 is disposed between the glass plates 111 and 112 and extends between the two ends 121 and 122 while branching off.

[0187] The flat harness 120 of the vehicle window glass with flat harness 100I1 has the same configuration as the flat harness 120 of the vehicle window glass with flat harness 100B1, and is a foil-shaped connecting member in which linear foil conductors 120-1 are covered with an insulating layer 120-2.

[0188] <Functional member 140> The two functional members 140 are disposed between the glass plates 111 and 112. The two functional members 140 are disposed at the center in the left-right direction of the upper end (rear end) of the laminated glass 110 in a plan view, and at the center in the left-right direction of the lower end (front end) of the glass 110, respectively, and are located in portions that overlap with the ceramic layer 114. As an example, the two functional members 140 are bus bars to which heating wires are connected, antennas, etc.

[0189] <Vehicle window glass with flat harness 100I2> The vehicle window glass 100I2 with a flat harness includes a laminated glass 110, a flat harness 120, and two functional members 140. The vehicle window glass 100I2 with a flat harness has the same structure as the vehicle window glass 100H2 with a flat harness shown in Fig. 3K, and therefore a description thereof will be omitted.

[0190] <Pull-out end 125> The lead-out end 125 is the same as the lead-out end 125 shown in Figure 3K, and therefore a description thereof will be omitted.

[0191] <Vehicle window glass 50I3> The vehicle window glass 50I3 used as a rear window is, for example, the same as the vehicle window glass 50B3 shown in FIG. 3A.

[0192] <Summary of Figure 3L> The vehicle window glass system 200 with flat harness shown in Figure 3L can transmit control signals and power between an ECU, power supply, etc. and four functional components 140 via two flat harnesses 120 arranged on the laminated glass 110 of the vehicle window glasses 100I1 and 100I2 with flat harnesses and the pull-out end 125.

[0193] <More specific configuration example> Figures 4A and 4B are diagrams showing an example of a more specific configuration of the vehicle window glass 100G1 and 100G2 with a flat harness shown in Figure 3J. Figures 4A and 4B show a cross section of the entire vehicle window glass 100G1 with a flat harness and a cross section of a portion on the front end side of the vehicle window glass 100G2 with a flat harness.

[0194] The front end (lower end) of the vehicle window glass 100G1 with a flat harness, which is used as a windshield, is inserted into the clamping structure of the cowl louver 15. FIGS. 4A and 4B show a cross section of a portion of the cowl louver 15 extending in the left-right direction, which has a U-shaped clamping structure that clamps the front end (lower end) of the vehicle window glass 100G1 with a flat harness. The cowl louver 15 has a configuration in which a plurality of clamping structures are attached to a plate-like member extending in the left-right direction, and are spaced apart in the left-right direction. In the portion of the cowl louver 15 where there is no clamping structure, the front end (lower end) of the vehicle window glass 100G1 with a flat harness is not inserted into the cowl louver 15. The adhesive 20 on the lower end side is located above the cowl louver 15. An end 121 of the flat harness 120 of the vehicle window glass 100G1 with a flat harness is routed from the lower end side surface of the glass plate 111 to the interior side along the interior-side main surface, and the laminated glass 110 is fixed to the flange 11A on the lower end side of the opening 11WS with an adhesive 20 from above the end 121 to the lower end side. In other words, the end 121 of the flat harness 120 of the vehicle window glass 100G1 with a flat harness is passed between the main surface 112B and the adhesive 20, and routed inside the adhesive 20 in a plan view of the vehicle window glass 100G1 with a flat harness.

[0195] 4A, the opening 11WS for the windshield and the opening 11RF for the roof glass are connected, so that the end 122 of the flat harness 120 of the vehicle window glass 100G1 with a flat harness and the end 121 of the flat harness 120 of the vehicle window glass 100G2 with a flat harness are connected at the boundary between the openings 11WS and 11RF. The boundary between the openings 11WS and 11RF may be covered with a resin or metal cover member to prevent the intrusion of rainwater, etc. Covering the boundary between the openings 11WS and 11RF with a cover member allows the end 122 of the flat harness 120 of the vehicle window glass 100G1 with a flat harness and the end 121 of the flat harness 120 of the vehicle window glass 100G2 with a flat harness to be connected over the shortest distance.

[0196] At the upper end side of the vehicle window glass 100G1 with a flat harness, the interior-side main surface of the glass plate 112 is fixed to the flange 11A at the upper end side of the opening 11WS with an adhesive 20. At the front end side of the vehicle window glass 100G2 with a flat harness, the interior-side main surface of the glass plate 112 is fixed to the flange 11A at the front end side of the opening 11RF with an adhesive 20.

[0197] In Figure 4B, a front header 11B is located at the boundary between the windshield opening 11WS and the roof glass opening 11RF. The front header 11B is a protruding portion on the outer surface of the flange 11A between the upper end of the opening 11WS and the front end of the opening 11RF. The flange 11A having the front header 11B extends from the left end to the right end of the vehicle body 10, and the front header 11B also extends from the left end to the right end of the vehicle body 10.

[0198] Therefore, the end 122 of the flat harness 120 of the vehicle window glass 100G1 with flat harness and the end 121 of the flat harness 120 of the vehicle window glass 100G2 with flat harness are routed and connected in a manner that bypasses the inside of the passenger compartment of the flange 11A having the front header 11B.

[0199] An end 122 of the flat harness 120 of the vehicle window glass 100G1 with a flat harness is passed between the main surface 112B and the adhesive 20, and is routed inward of the adhesive 20 in a plan view of the vehicle window glass 100G1 with a flat harness. Similarly, an end 121 of the flat harness 120 of the vehicle window glass 100G2 with a flat harness is passed between the main surface 112B and the adhesive 20, and is routed inward of the adhesive 20 in a plan view of the vehicle window glass 100G2 with a flat harness.

[0200] In this way, even in a vehicle body 10 in which a front header 11B is located at the boundary between an opening 11WS for a windshield and an opening 11RF for a roof glass, the end 122 of the flat harness 120 of the vehicle window glass 100G1 with a flat harness can be connected to the end 121 of the flat harness 120 of the vehicle window glass 100G2 with a flat harness.

[0201] <Modification of vehicle window glass with flat harness> 5A, 5B, and 5C are diagrams showing an example of the configuration of vehicle window glasses 100I, 100J, and 100K with flat harnesses according to modified embodiments. Only the laminated glass 110, ceramic layer 114, flat harness 120, end portion 121, end portion 122, and intermediate extension portion 123 of the vehicle window glasses 100I, 100J, and 100K are shown in FIG. As an example, the vehicle window glasses with flat harnesses 100I, 100J, and 100K can be used in place of the vehicle window glasses with flat harnesses 100A1, 100A2, 100B1, 100B2, 100C1, 100C2, 100D1, 100D2, 100E1, 100E2, 100E3, 100F1, 100F2, 100G1, 100G2, 100G3, 100H1, and 100H2 described above.

[0202] Here, of the four sides of the laminated glass 110, the side extending front to back on the right side is referred to as the first side, the side connected to one end side of the first side (for example, the front side) and extending left to right is referred to as the second side, the side connected to the other end side of the first side (for example, the rear side) and extending left to right is referred to as the third side, and the side extending front to back on the left side is referred to as the fourth side. The first side and the fourth side face each other, and the second side and the third side face each other.

[0203] In the vehicle window glass 100I with a flat harness shown in FIG. 5A, the end 121 of the flat harness 120 is located on the second side connected to one end side (for example, the front side) of the first side, the intermediate extension portion 123 extends in the front-to-rear direction along the first side, and the end 122 is located on the other end side (for example, the rear side) of the first side and is pulled out to the right.

[0204] 5B, an end 121 of the flat harness 120 is located on the second side connected to one end of the first side (for example, the front side), and an intermediate extending portion 123 extends in an L-shape along the first and third sides. An end 122 faces the first side and is located on the fourth side connected to the second side, and is pulled out to the left from the other end of the fourth side (for example, the rear side).

[0205] In addition, in FIG. 5B, the flat harness 120 is arranged at the end of the laminated glass 110 along two adjacent sides of the four sides of the laminated glass 110.

[0206] In the vehicle window glass 100K with a flat harness shown in Fig. 5C, the end 121 of the flat harness 120 is pulled out to the right from one end side (for example, the front side) of the first side, the intermediate extending portion 123 extends in the front-to-rear direction along the first side, and the end 122 is located at the other end side (for example, the rear side) of the first side and pulled out to the right. That is, in the vehicle window glass 100K with a flat harness shown in Fig. 5C, the end 121 and the end 122 are located on the first side.

[0207] <Effects> The vehicle window glass system (200) with a flat harness includes: a first vehicle window glass (100, 100S) having a main surface on the vehicle exterior side and a main surface on the vehicle interior side; a first flat harness (120) having a first end (121) which is one end, a second end (122) which is the other end, and a first intermediate extension portion (123) between the first end (121) and the second end (122), the first intermediate extension portion (123) being fixed to the main surface on the vehicle interior side of the first vehicle window glass (100, 100S); The second flat harness (120) includes a second vehicle window glass (100, 100S) having a main surface facing the outside of the vehicle compartment and a main surface facing the inside of the vehicle compartment, a third end (121) that is one end, a fourth end (122) that is the other end, and a second intermediate extension portion (123) between the third end (121) and the fourth end (122), wherein the second intermediate extension portion (123) is fixed to the main surface facing the inside of the vehicle compartment of the second vehicle window glass (100, 100S), and the third end (121) is connected to the second end (122). Therefore, the first flat harness (120) and the second flat harness (120) can be provided on the first vehicle window glass (100, 100S) and the second vehicle window glass (100, 100S), respectively.

[0208] Therefore, it is possible to provide a vehicle window glass system (200) with a flat harness that can provide a location for arranging the first flat harness (120) and the second flat harness (120). In recent years, the number of electrical components mounted on vehicles has increased, resulting in a shortage of space for arranging wire harnesses, etc. However, by using the vehicle window glass system (200) with a flat harness, the first flat harness (120) and the second flat harness (120) can ensure signal transmission lines and power transmission lines.

[0209] The vehicle window glass system (200) with a flat harness includes a first laminated glass (110) having a first glass sheet (111) arranged on the outside of the vehicle cabin, a second glass sheet (112) arranged closer to the interior of the vehicle cabin than the first glass sheet (111), and a first intermediate film (113) arranged between the first glass sheet (111) and the second glass sheet (112), and a first flat harness (120) having a first end (121) that is one end, a second end (122) that is the other end, and a first intermediate extension portion (123) between the first end (121) and the second end (122), wherein the first intermediate extension portion (123) is arranged between the first glass sheet (111) and the second glass sheet (112), and the first end (121) is arranged between the first glass sheet (111) and the second glass sheet (112), and the first intermediate extension portion (123 ... the first flat harness (120) being located between or outside the first glass plate (111) and the second glass plate (112), and the second end (122) being located outside the first glass plate (111) and the second glass plate (112); a vehicle window glass (100, 100S) having a main surface on the outside of the vehicle compartment and a main surface on the inside of the vehicle compartment; and the second flat harness (120) having a third end (121) which is one end, a fourth end (122) which is the other end, and a second intermediate extension portion (123) between the third end (121) and the fourth end (122), the second intermediate extension portion (123) being fixed to the main surface on the inside of the vehicle compartment of the vehicle window glass (100, 100S), and the third end (121) being connected to the second end (122). Therefore, the first laminated glass (110) and the vehicle window glass (100, 100S) can be provided with the first flat harness (120) and the second flat harness (120), respectively.

[0210] Therefore, it is possible to provide a vehicle window glass system (200) with a flat harness that can provide a location for arranging the first flat harness (120) and the second flat harness (120). In recent years, the number of electrical components mounted on vehicles has increased, resulting in a shortage of space for arranging wire harnesses, etc. However, by using the vehicle window glass system (200) with a flat harness, the first flat harness (120) and the second flat harness (120) can ensure signal transmission lines and power transmission lines.

[0211] The glass substrate may further include a functional member (140) disposed between the first glass plate (111) and the second glass plate (112) and connected to the first intermediate extension portion (123) of the first flat harness (120). The first intermediate extension portion (123) of the first flat harness (120) can be used as a signal transmission line or a power transmission line, and can transmit signals or power to the functional member (140) disposed between the first glass plate (111) and the second glass plate (112).

[0212] The first flat harness (120) may further include a branch line (124) that is arranged between the first glass plate (111) and the second glass plate (112), branches off from the first intermediate extension portion (123), and is connected to the functional member (140). The first intermediate extension portion (123) between the first end portion (121) and the second end portion (122) of the first flat harness (120) provided between the first glass plate (111) and the second glass plate (112) of the first laminated glass (110) can be used as a signal transmission line or a power transmission line, and the branch line (124) branching off from the first intermediate extension portion (123) can be used as a signal transmission line or a power transmission line.

[0213] The first laminated glass (110) may further have a first shielding layer (ceramic layer 114) formed on the main surface of the first glass plate (111) facing the interior of the vehicle, and the first intermediate extension portion (123) may be arranged in a portion that overlaps with the first shielding layer (ceramic layer 114) in a plan view. When viewed from outside the vehicle, the first intermediate extension portion (123) can be hidden by the first shielding layer (ceramic layer 114), making it possible to provide a vehicle window glass system (200) with a flat harness that looks good.

[0214] Furthermore, the first laminated glass (110) may have a rectangular shape having four sides in a plan view, and the first flat harness (120) may be arranged at the end of the first laminated glass (110) along one of the four sides. The first flat harness (120) may be arranged near the outer edge of the first laminated glass (110), and the empty space near the outer edge of the first laminated glass (110) can be used to provide a location for the first flat harness (120). Furthermore, by arranging the first flat harness (120) near the outer edge of the first laminated glass (110), the first flat harness (120) does not obstruct the view, ensuring good visibility.

[0215] Alternatively, the first end (121) may be located on a second side connected to one end of the first side, which is one of the four sides, and the second end (122) may be located on a third side connected to the other end of the first side. The first flat harness (120) can be extended along one side of the outer edge of the first laminated glass (110), providing a placement location for the first flat harness (120) over a certain length. Alternatively, the end 121 may be located on a second side connected to one end of the first side, and the end 122 may be located on the first side. Alternatively, the end 121 may be located on a second side connected to one end of the first side, and the end 122 may be located on a fourth side opposite the first side and connected to the second side. Alternatively, the end 121 and the end 122 may be located on the first side.

[0216] The vehicle window glass (100, 100S) may further have a second shielding layer (ceramic layer 114) formed on the main surface facing the interior of the vehicle, and the second intermediate extension portion (123) may be arranged in a portion that overlaps with the second shielding layer (ceramic layer 114) in a plan view. When viewed from outside the vehicle, the second intermediate extension portion (123) can be hidden by the second shielding layer (ceramic layer 114), making it possible to provide a vehicle window glass system (200) with a flat harness that looks good.

[0217] Furthermore, the vehicle window glass (100, 100S) may have a rectangular shape having four sides in a plan view, and the second flat harness (120) may be arranged at the end of the vehicle window glass (100, 100S) along one of the four sides or two adjacent sides. The second flat harness (120) may be arranged near the outer edge of the vehicle window glass (100, 100S), and the empty space near the outer edge of the vehicle window glass (100, 100S) can be used to provide a location for the second flat harness (120). Furthermore, by arranging the second flat harness (120) near the outer edge of the vehicle window glass (100, 100S), the second flat harness (120) does not obstruct the view, ensuring good visibility.

[0218] The cable may further include a lead-out end (125) connected to the second end (122) and the third end (121) and extending outside the first laminated glass (110) and the vehicle window glass (100, 100S). Since signals and power can be transmitted via the lead-out end (125) that is drawn out from between the first laminated glass (110) and the vehicle window glass (100, 100S), the degree of freedom in designing the transmission paths of signals and power in the vehicle is improved.

[0219] The glass substrate may further include a functional member (140) disposed between the first glass plate (111) and the second glass plate (112), and the first end (121) may be connected to the functional member (140) between the first glass plate (111) and the second glass plate (112). When the first end (121) is connected to the functional member (140) between the first glass plate (111) and the second glass plate (112), signals and power can be transmitted to the functional member (140) via the lead-out end (125).
