Description

[Technical Field]

[0001] The present disclosure relates to a vehicle window glass 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 with a flat harness that can provide a location for arranging the flat harness. [Means for solving the problem]

[0007] A vehicle window glass with a flat harness according to an embodiment of the present disclosure includes a glass plate having a main surface on the outside of the vehicle cabin and a main surface on the inside of the vehicle cabin, a flat harness having a first end which is one end, a second end which is the other end, and an intermediate extension portion between the first end and the second end, wherein the intermediate extension portion includes a flat harness fixed to the main surface on the inside of the vehicle cabin. [Effects of the Invention]

[0008] A vehicle window glass 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 a vehicle window glass 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 with a flat harness in this embodiment can be used as roof glass attached to the ceiling of a vehicle, a windshield (front glass) 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> FIG. 1 is a diagram showing an example of the configuration of a vehicle 1 to which a vehicle window glass 100 with a flat harness according to an embodiment is attached.

[0016] The vehicle 1 includes a vehicle body 10 and a vehicle window glass with a flat harness 100. The vehicle 1 is, for example, an electric vehicle (EV), a plug-in hybrid electric vehicle (PHEV), a hybrid vehicle (HV), a gasoline vehicle, a diesel vehicle, or other automobile. 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.

[0018] The vehicle window glass included in the vehicle window glass 100 with a flat harness may be laminated glass or single-pane (tempered glass), but as an example, we will explain a form including laminated glass in which the vehicle window glass 100 with a flat harness is placed in the opening 11WS.

[0019] <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.

[0020] 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.

[0021] 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.

[0022] <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 the flange 11A by an adhesive 20. As an example, the adhesive 20 is applied to the main surface 112B of the glass plate 112 of the laminated glass 110 in a plan view, along the entire periphery of the outer edge of the laminated glass 110 in a plan view. However, the adhesive 20 may be interrupted in a partial section around the periphery of the outer edge of the laminated glass 110 in a plan view.

[0023] The laminated glass 110 is formed by bonding a glass plate 111 located on the exterior side of the vehicle body 10 to a glass plate 112 located on the interior side of the vehicle body 10 via an intermediate film 113 disposed between the glass plates 111 and 112.

[0024] <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.

[0025] 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.

[0026] 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.

[0027] 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.

[0028] 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.

[0029] 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.

[0030] 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).

[0031] 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.

[0032] <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.

[0033] <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.

[0034] 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.

[0035] 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.

[0036] 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 heat ray reflecting 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.

[0037] <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.

[0038] 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.

[0039] The flat harness 120 has an end portion 121, an end portion 122, and an intermediate extending portion 123. The end portion 121 is an example of a first end portion. The end portion 122 is an example of a second end portion. 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.

[0040] 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.

[0041] 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.

[0042] 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.

[0043] 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.

[0044] 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.

[0045] 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.

[0046] 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.

[0047] 2A, the intermediate extending portion 123 is not limited to being disposed between the intermediate films 113. FIGS. 2B and 2C are diagrams showing examples of variations in the position of the intermediate extending portion 123.

[0048] 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.

[0049] 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.

[0050] 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 be arranged so that the intermediate extension portion 123 is sandwiched between two layers of intermediate film 113 as shown in Figure 2A, and the remaining foil-like conductors 120-1 may be arranged so that the intermediate extension portion 123 is in contact with the ceramic layer 114 as shown in Figure 2B.

[0051] 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 extending portion 123 arranged between the glass plates 111 and 112. The intermediate extending portion 123 of the flat harness 120 arranged on the main surface 112B of the glass plate 112 is preferably provided 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.

[0052] 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.

[0053] Furthermore, 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 on the outdoor main surface 112A of the glass plate 112 so as to be in contact with the ceramic layer 114.

[0054] 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.

[0055] 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.

[0056] 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.

[0057] <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.

[0058] 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.

[0059] 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.

[0060] 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.

[0061] 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.

[0062] 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.

[0063] <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.

[0064] 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.

[0065] 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.

[0066] <Vehicle window glass 100 with flat harness including flat harnesses 120 and 130> 2H is a diagram showing an example of a cross-sectional configuration of a vehicle window glass 100 with a flat harness including 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 second flat harness.

[0067] The vehicle window glass 100 with a flat harness shown in FIG. 2H includes a laminated glass 110 and flat harnesses 120 and 130.

[0068] The flat harness 120 has an end portion 121, an end portion 122, and an intermediate extension portion 123. 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.

[0069] The flat harness 130 has a third end 131, a fourth end 132, and an intermediate extension 133. The intermediate extension 133 is an example of a second intermediate extension. 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.

[0070] The fourth end 132 and the intermediate extending portion 133 of the flat harness 130 are disposed on the main surface 112B of the glass plate 112. The third end 131 is connected to the end of the intermediate extending portion 133 on the −X direction side, is located outside the laminated glass 110, and is not fixed to the laminated glass 110. The fourth end 132 and the intermediate extending portion 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.

[0071] The third end 131 and the fourth end 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 third end 131 and the fourth end 132, and connects the third end 131 and the fourth end 132.

[0072] 2A, the third end 131 can be connected to an electrical component, a power source, a ground potential point, or the like of the vehicle 1. The fourth 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 fourth end 132 to the end 121 means that the fourth 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 fourth end 132 and the end 121. This coupling is capacitive coupling.

[0073] By joining the end portion 121 and the fourth 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.

[0074] 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.

[0075] <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.

[0076] 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.

[0077] 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.

[0078] 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.

[0079] 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.

[0080] 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.

[0081] 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.

[0082] <Mounting variations of vehicle window glass 100 with flat harness> Hereinafter, variations in the mounting of the vehicle window glass 100 with a flat harness will be described with reference to FIGS. 3A to 3K.

[0083] 3A to 3K show the windshield (WS), roof glass (RF), and rear glass (BL) in plan view, from top to bottom. In Figures 3A to 3K, 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.

[0084] <Vehicle 1 shown in Figure 3A> The vehicle 1 shown in FIG. 3A includes a vehicle window glass 100A1 with a flat harness as a windshield, and also includes vehicle window glasses 50A2 and 50A3 as a roof glass and a rear glass, respectively.

[0085] The vehicle window glass 100A1 with a flat harness includes a laminated glass 110, a flat harness 120, and a functional member 140. The vehicle window glass 100A1 with a flat harness is used as a windshield and includes the functional member 140. Therefore, for example, the vehicle window glass 100 with a flat harness shown in FIGS. 2I and 2J can be realized. The ceramic layer 114 of the vehicle window glass 100A1 with a flat harness shown in FIG. 3A has a protrusion 114A in the center of the rear end of the windshield in the left-right direction to conceal the surroundings of a camera for capturing images of the forward direction. 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. The flat harness 120 of the vehicle window glass 100A1 with a flat harness includes an end portion 121, an end portion 122, and an intermediate extension portion 123. In the vehicle window glass 100A1 with a flat harness, the flat harness 120 has an intermediate extending portion 123 extending between an end portion 121 located at the front end (lower end) on the right side and an end portion 122 located at the rear end (upper end) on the right side. The outer edge of the laminated glass 110 is rectangular, and the laminated glass 110 has four sides. The right side of the four sides of the laminated glass 110 extending front to rear is referred to as the first side, and the side connected to one end side (the front side, for example) of the first side and extending left to right is referred to as the second side. The other side of the four sides of the laminated glass 110 connected to the other end side (the rear side, for example) of the first side and extending left to right is referred to as the third side, and the left side of the four sides extending front to rear 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 100A1 with a flat harness, an end 121 of the flat harness 120 is located on a second side connected to one end side (for example, the front side) of the first side, and an end 122 is located on a third side connected to the other end side (for example, the rear side) of the first side. In addition, in Fig. 3A, the flat harness 120 is arranged at an end of the laminated glass 110 along one of the four sides of the laminated glass 110.

[0086] The vehicle window glasses 50A2 and 50A3 used as roof glass and rear glass, respectively, have, as an example, a configuration in which a ceramic layer 114 is provided on the outer edge of a single glass sheet 40. Note that at least one of the vehicle window glasses 50A2 and 50A3 may have a configuration in which the ceramic layer 114 is provided along the outer edge of a laminated glass.

[0087] 3A, the functional member 140 is located on the rear side (upper side) of the convex portion 114A, for example. The vehicle window glass 100A1 with a flat harness shown in FIG. 3A is capable of transmitting signals, power, etc. between the end portion 121 and the end portion 122 of the flat harness 120 arranged on the laminated glass 110, and is also capable of transmitting signals, power, etc. between the end portion 121 or the end portion 122 and the functional member 140.

[0088] <Vehicle 1 shown in Figure 3B> The vehicle 1 shown in Fig. 3B includes a vehicle window glass 100B1 with a flat harness as a windshield, a vehicle window glass 100B2 with a flat harness as a roof glass, and a vehicle window glass 50B3 as a rear glass. Fig. 3C is a diagram showing an example of the cross-sectional configuration of the vehicle window glasses 100B1 and 100B2 with flat harnesses.

[0089] 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 3C.

[0090] The vehicle window glass 100B2 with a flat harness used as a roof glass includes a laminated glass 110, a functional member 140, and a flat harness 150. Similar to the laminated glass 110 of the vehicle window glass 100B1 with a flat harness, the laminated glass 110 includes glass plates 111 and 112 and an interlayer film 113. The laminated glass 110 of the vehicle window glass 100B2 with a flat harness includes a ceramic layer and a Low-E film, but these are omitted from FIG. 3C . The glass plate 111 has an exterior-facing main surface 111A and an interior-facing main surface 111B. The glass plate 112 has an exterior-facing main surface 112A and an interior-facing main surface 112B.

[0091] The functional member 140 is disposed between the glass plates 111 and 112 of the laminated glass 110. In plan view, the functional member 140 is disposed in the center of the laminated glass 110 excluding the ends along the outer edge, and is surrounded by the ceramic layer 114 in plan view. A terminal of the functional member 140 is connected to an end 152 of the flat harness 150.

[0092] The flat harness 150 has a similar configuration to the flat harness 120 and is a foil-shaped connecting member in which linear foil conductors are coated with an insulating layer. The flat harness 150 needs to have at least one foil conductor, but may have multiple foil conductors. When the flat harness 150 has multiple foil conductors, the multiple foil conductors only need to be insulated from each other by an insulating layer. The flat harness 150 has end portions 151 and 152 and an intermediate extension portion 153. The end portions 151 and 152 are both ends of the flat harness 150, and the intermediate extension portion 153 extends between the end portions 151 and 152.

[0093] The end 151 is disposed outside the glass plates 111 and 112 of the vehicle window glass 100B2 with a flat harness, and is connected to the end 122 of the flat harness 120. The end 152 and the intermediate extending portion 153 are disposed between the glass plates 111 and 112 of the vehicle window glass 100B2 with a flat harness. The end 152 is connected to a terminal of the functional member 140. The end 121 of the flat harness 120 of the vehicle window glass 100B1 with a flat harness may be connected to an ECU that controls the functional member 140, a power source, or the like.

[0094] The vehicle window glass 50B3 used as a rear window is, for example, the same as the vehicle window glass 50A3 shown in FIG. 3A.

[0095] The vehicle window glass 100B1 with a flat harness shown in Figure 3B can transmit control signals and power to the functional component 140 via a flat harness 120 arranged in the laminated glass 110 of the vehicle window glass 100B1 with a flat harness and a flat harness 150 arranged in the laminated glass 110 of the vehicle window glass 100B2 with a flat harness.

[0096] <Vehicle 1 shown in Figure 3D> The vehicle 1 shown in FIG. 3D includes a vehicle window glass 100C1 with a flat harness as a windshield, a vehicle window glass 100C2 with a flat harness as a roof glass, and a vehicle window glass 50C3 as a rear glass.

[0097] The vehicle window glass 100C1 with a flat harness used as a windshield is the same as the vehicle window glass 100B1 with a flat harness shown in FIG. 3B.

[0098] The vehicle window glass 100C2 with a flat harness used as a roof glass includes a laminated glass 110, a functional member 140, and a flat harness 150. The vehicle window glass 100C2 with a flat harness may include a single sheet of glass instead of the laminated glass 110. In this case, the flat harness 150 is fixed to the main surface of the single sheet of glass on the interior side.

[0099] As an example, the functional member 140 is disposed on the exterior main surface of the laminated glass 110, in the center in the left-right direction of the rear end of the laminated glass 110. As an example, the functional member 140 is an antenna attached to the roof of the vehicle 1, and may be a shark fin antenna. The functional member 140 is disposed in a position overlapping with the ceramic layer 114 of the laminated glass 110 of the vehicle window glass 100C2 with a flat harness in a plan view.

[0100] The flat harness 150 is longer than the flat harness 150 shown in Fig. 3B. The intermediate extending portion 153 extends rearward from the front end of the right side of the laminated glass 110 of the vehicle window glass 100C2 with the flat harness, along the outer edge of the right side, and bends leftward at the rear end of the right side, with the end portion 152 connected to the functional member 140. The end portion 152 and the functional member 140 may be directly connected by providing a through-hole in the glass plate 111, or may be coupled by overlapping the end portion 152 and the functional member 140 with the glass plate 111 sandwiched therebetween. This coupling is capacitive coupling.

[0101] The end 151 is connected to the end 122 of the flat harness 120. The end 121 of the flat harness 120 may be connected to an ECU that controls the functional member 140, a power source, or the like.

[0102] The vehicle window glass 50C3 used as a rear window is, for example, the same as the vehicle window glass 50A3 shown in FIG. 3A.

[0103] The vehicle window glass 100C1 with a flat harness shown in Figure 3D can transmit control signals and power to the functional component 140 via a flat harness 120 arranged in the laminated glass 110 of the vehicle window glass 100C1 with a flat harness and a flat harness 150 arranged in the laminated glass 110 of the vehicle window glass 100C2 with a flat harness.

[0104] <Vehicle 1 shown in Figure 3E> The vehicle 1 shown in FIG. 3E includes a vehicle window glass 100D1 with a flat harness as a windshield, a vehicle window glass 100D2 with a flat harness as a roof glass, and a vehicle window glass 50D3 as a rear glass.

[0105] The vehicle window glass 100D1 with a flat harness used as a windshield is the same as the vehicle window glass 100B1 with a flat harness shown in FIG. 3B.

[0106] A vehicle window glass 100D2 with a flat harness used as a roof glass includes a laminated glass 110, two functional members 140, and a flat harness 150.

[0107] 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 light control elements that can change the light transmittance of the laminated glass 110, or lighting such as LEDs (Light Emitting Diodes). In a plan view, the functional members 140 are arranged at positions that overlap with the inner edges of the ceramic layer 114 of the laminated glass 110 of the vehicle window glass 100D2 with a flat harness, and a portion of the functional members 140 may be located inside the inner edges of the ceramic layer 114 in a plan view.

[0108] Since the flat harness 150 is connected to two functional members 140, the intermediate extension portion 153 connected to the end portion 151 branches into two branch lines and extends to the end portion 152 at the end of each branch line. The two end portions 152 are connected to the terminals of the two functional members 140, respectively.

[0109] The end 151 is connected to the end 122 of the flat harness 120. The end 121 of the flat harness 120 may be connected to an ECU that controls the functional member 140, a power source, or the like.

[0110] The vehicle window glass 50D3 used as a rear window is, for example, the same as the vehicle window glass 50A3 shown in FIG. 3A.

[0111] The vehicle window glass 100D1 with a flat harness shown in Figure 3E can transmit control signals and power to the functional component 140 via a flat harness 120 arranged in the laminated glass 110 of the vehicle window glass 100D1 with a flat harness and a flat harness 150 arranged in the laminated glass 110 of the vehicle window glass 100D2 with a flat harness.

In the vehicle window glass 100E2 with a flat harness, the flat harness 120 has the intermediate extending portion 123 extending between the end portion 121 located at the front end on the right side and the end portion 122 located at the rear end on the right side.

[0118] The vehicle window glass 100E3 with a flat harness used as a rear glass includes a flat harness 150 arranged on the main surface of a single sheet glass 110S facing the interior. The flat harness 150 has an end portion 151, an end portion 152, and an intermediate extension portion 153.

The end 121 of the flat harness 120 of the vehicle window glass with flat harness 100E1 may be connected to an ECU that controls the functional member 140, a power source, or the like.

[0120] The vehicle window glasses 100E1 and 100E2 with flat harnesses shown in Fig. 3F can transmit control signals and power to the flat harness 150 of the vehicle window glass 100E3 with flat harness via the flat harness 120 arranged in the laminated glass 110 of the vehicle window glasses 100E1 and 100E2 with flat harnesses. The vehicle window glass 100E3 with flat harness can transmit the control signals and power transmitted via the flat harness 150 to the functional member 140. In this way, control signals and power can be transmitted to the functional member 140 of the vehicle window glass 100E3 with flat harness via the two flat harnesses 120 and the flat harness 150 of the vehicle window glasses 100E1 to 100E3 with flat harnesses.

[0121] The vehicle window glass 100E2 with a flat harness used as a roof glass may have a configuration as shown in Figures 3H and 3I. Figures 3H and 3I are diagrams showing an example of a variation of the vehicle window glass 100E2 with a flat harness shown in Figure 3G.

[0122] The vehicle window glass 100E2 with a flat harness shown in Figure 3H has a configuration in which the laminated glass 110 of the vehicle window glass 100E2 with a flat harness shown in Figure 3G is replaced with a single glass sheet 110S, and a flat harness 120 is provided on the main surface of the single glass sheet 110S facing the interior.

[0124] Even if the vehicle window glass 100E2 with a flat harness shown in Figures 3H and 3I is used instead of the vehicle window glass 100E2 with a flat harness shown in Figure 3G, control signals and power can be transmitted to the functional component 140 of the vehicle window glass 100E3 with a flat harness via the two flat harnesses 120 and the flat harness 150 of the vehicle window glasses 100E1 to 100E3 with flat harnesses.

[0125] <Vehicle 1 shown in Figure 3J> The vehicle 1 shown in FIG. 3J includes a vehicle window glass 100F1 with a flat harness as a windshield, a vehicle window glass 100F2 with a flat harness as a roof glass, and a vehicle window glass 50F3 as a rear glass.

[0126] The vehicle window glass 100F1 with a flat harness used as a windshield is the same as the vehicle window glass 100B1 with a flat harness shown in FIG. 3B.

[0127] Furthermore, the vehicle window glass 100F2 with a flat harness used as roof glass can be realized, for example, by a vehicle window glass 100 with a flat harness including a laminated glass 110 shown in Figures 2A to 2D and 2H, or a vehicle window glass 100 with a flat harness including a single-pane glass 110S shown in Figures 2E and 2F.

[0128] The vehicle window glass 50F3 used as a rear window is, for example, the same as the vehicle window glass 50A3 shown in FIG. 3A.

[0129] In the vehicle 1 shown in Fig. 3J, an electrical component 60 is disposed on the right B-pillar. Correspondingly, the vehicle window glass 100F2 with a flat harness used as a roof glass has a configuration in which the end portion 122 of the flat harness 120 of the vehicle window glass 100E2 with a flat harness shown in Fig. 3F is moved to the position of the right B-pillar.

[0130] An end 122 of the vehicle window glass with flat harness 100F1 is connected to an end 121 of the vehicle window glass with flat harness 100F2, and the end 122 of the vehicle window glass with flat harness 100F2 is connected to an electrical component 60 arranged on the B-pillar. The end 121 of the flat harness 120 of the vehicle window glass with flat harness 100F1 may be connected to an ECU that controls the electrical component 60, a power source, or the like.

[0131] The vehicle window glasses 100F1 and 100F2 with flat harnesses shown in Fig. 3J can transmit control signals and power to the electrical equipment 60 arranged on the B-pillar via the two flat harnesses 120. In this way, control signals and power can be transmitted to the electrical equipment 60 arranged on the B-pillar via the two flat harnesses 120 of the vehicle window glasses 100F1 and 100F2 with flat harnesses.

[0132] <Vehicle 1 shown in Figure 3K> The vehicle 1 shown in FIG. 3K includes a vehicle window glass 100G1 with a flat harness as a windshield, a vehicle window glass 100G2 with a flat harness as a roof glass, and a vehicle window glass 100G3 with a flat harness as a rear glass.

[0133] The vehicle window glass 100G1 with a flat harness used as a windshield is the same as the vehicle window glass 100B1 with a flat harness shown in FIG. 3B.

[0134] Moreover, the vehicle window glass 100G2 with a flat harness used as a roof glass is, for example, the same as the vehicle window glass 100E2 with a flat harness shown in FIG. 3F.

[0135] Furthermore, the vehicle window glass 100G3 with a flat harness used as a rear glass can be realized, for example, by the vehicle window glass 100 with a flat harness including the laminated glass 110 shown in Figures 2A to 2D and 2H, or the vehicle window glass 100 with a flat harness including the single glass 110S shown in Figures 2E and 2F. Here, as an example, a form will be described in which the vehicle window glass 100G2 with a flat harness is configured by the vehicle window glass 100 with a flat harness shown in Figure 2F.

[0136] The flat harness 120 of the vehicle window glass 100G3 with a flat harness used as a rear glass has an end portion 121, an end portion 122, and an intermediate extending portion 123. In the vehicle window glass 100G3 with a flat harness, the flat harness 120 has the intermediate extending portion 123 extending between the end portion 121 located at the front end (upper end) on the right side and the end portion 122 located at the rear end (lower end) on the right side.

[0137] An end 122 of the vehicle window glass with flat harness 100G1 is connected to an end 121 of the vehicle window glass with flat harness 100G2, and an end 122 of the vehicle window glass with flat harness 100G2 is connected to an end 121 of the vehicle window glass with flat harness 100G3.

[0138] Either the end 121 of the flat harness 120 of the vehicle window glass with flat harness 100G1 or the end 122 of the vehicle window glass with flat harness 100G3 may be connected to an ECU, a power source, etc., and the other may be connected to an electrical component, etc.

[0139] The vehicle window glasses 100G1 to 100G3 with flat harnesses shown in Figure 3K can connect the front section and rear section of the vehicle 1 via three flat harnesses 120 arranged on the laminated glass 110 or single-pane glass 110S installed in the vehicle 1, and can transmit control signals and power between the ECU, power source, etc. and electrical equipment, etc.

[0140] <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 3K. 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.

[0141] 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.

[0142] 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.

[0143] 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.

[0144] 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.

[0145] 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.

[0146] 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.

[0147] 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.

[0148] <Modification of vehicle window glass with flat harness> 5A, 5B, and 5C are diagrams showing an example of the configuration of vehicle window glasses 100H, 100I, and 100J 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 100H, 100I, and 100J with flat harnesses are shown in FIG. The vehicle window glasses with flat harnesses 100H, 100I, and 100J can be used, for example, in place of the vehicle window glasses with flat harnesses 100A1, 100B1, 100C1, 100C2, 100D1, 100D2, 100E1, 100E2, 100E3, 100F1, 100F2, 100G1, 100G2, and 100G3 described above.

[0149] 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.

[0150] In the vehicle window glass 100H with a flat harness shown in Figure 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.

[0151] 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).

[0152] 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.

[0153] In the vehicle window glass 100J 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 100J with a flat harness shown in Fig. 5C, the end 121 and the end 122 are located on the first side.

[0154] <Effects> The vehicle window glass 100 with a flat harness includes a glass plate (110, 110S) having a main surface facing the outside of the vehicle cabin and a main surface facing the inside of the vehicle cabin, and a flat harness 120 having an end 121 which is one end, an end 122 which is the other end, and an intermediate extending portion 123 between the end 121 and the end 122, the intermediate extending portion 123 including the flat harness 120 fixed to the main surface facing the inside of the vehicle cabin. Therefore, the flat harness 120 can be provided on the glass plate (110, 110S).

[0155] Therefore, it is possible to provide a vehicle window glass 100 with a flat harness that can provide a place to arrange the flat harness 120. In recent years, the number of electrical components mounted on vehicles has increased, resulting in a shortage of space to arrange wire harnesses and the like, but by using the vehicle window glass 100 with a flat harness, the flat harness 120 can ensure signal transmission lines and power transmission lines.

[0156] A vehicle window glass 100 with a flat harness (100A1, 100B1, 100C1, 100D1, 100E1, 100E2, 100F1, 100G1, 100G2, 100G3) includes a laminated glass 110 having a glass sheet 111 arranged on the outside of the vehicle interior, a glass sheet 112 arranged closer to the interior of the vehicle than the glass sheet 111, and an intermediate film 113 arranged between the glass sheets 111 and 112, and a flat harness 120 having an end 121 that is one end, an end 122 that is the other end, and an intermediate extending portion 123 between the end 121 and the end 122, wherein the intermediate extending portion 123 is arranged between the glass sheets 111 and 112, and the end 121 and the end 122 are located outside the glass sheets 111 and 112. Therefore, a flat harness 120 can be provided between the glass plates 111 and 112 of the laminated glass 110, and the intermediate extension portion 123 provided between the end portion 121 and the end portion 122 can be used as a signal transmission line or a power transmission line.

[0157] Therefore, it is possible to provide a vehicle window glass 100 with a flat harness (100A1, 100B1, 100C1, 100D1, 100E1, 100E2, 100F1, 100G1, 100G2, 100G3) that can provide a place to place the flat harness 120. In recent years, the number of electrical components mounted on vehicles has increased, resulting in a shortage of space to place wire harnesses and the like. However, by using the vehicle window glass 100 with a flat harness, the flat harness 120 can ensure signal transmission lines and power transmission lines.

[0158] The flat harness 120 may further include a functional member 140 that is disposed between the glass plates 111 and 112 and connected to the intermediate extension portion 123 of the flat harness 120. The intermediate extension portion 123 provided between the end portion 121 and the end portion 122 can be used as a signal transmission line or a power transmission line, and can transmit signals or power to the functional member 140 provided between the glass plates 111 and 112.

[0159] The flat harness 120 may further include a branch line 124 that is arranged between the glass plates 111 and 112, branches off from the intermediate extending portion 123, and is connected to the functional member 140. The intermediate extending portion 123 between the end portion 121 and the end portion 122 of the flat harness 120 provided between the glass plates 111 and 112 of the 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 intermediate extending portion 123 can be used as a signal transmission line or a power transmission line.

[0160] The laminated glass 110 may further include a ceramic layer 114 formed on the main surface of the glass plate 111 facing the interior of the vehicle, and the intermediate extending portion 123 may be disposed in a portion that overlaps with the ceramic layer 114 in a plan view. When viewed from outside the vehicle, the intermediate extending portion 123 can be hidden by the ceramic layer 114, making it possible to provide a vehicle window glass 100 with a flat harness that looks good.

[0161] Furthermore, the laminated glass 110 has a rectangular shape having four sides in a plan view, and the flat harness 120 may be disposed along one of the four sides at the edge of the laminated glass 110. The flat harness 120 can be disposed near the outer edge of the laminated glass 110, and an empty space near the outer edge of the laminated glass 110 can be used to provide a location for the flat harness 120. Furthermore, by disposing the flat harness 120 near the outer edge of the laminated glass 110, the flat harness 120 does not obstruct the view, ensuring good visibility.

[0162] Alternatively, end 121 may be located on a second side connected to one end of a first side, which is one of the four sides, and end 122 may be located on a third side connected to the other end of the first side. The flat harness 120 can be extended along one side of the outer edge of the laminated glass 110, providing a location for arranging the flat harness 120 over a certain length. Alternatively, end 121 may be located on a second side connected to one end of the first side, and end 122 may be located on the first side. Alternatively, end 121 may be located on a second side connected to one end of the first side, and end 122 may be located on a fourth side opposite the first side and connected to the second side. Alternatively, end 121 and end 122 may be located on the first side.

[0163] The vehicle window glass 100 with a flat harness includes a laminated glass 110 having a glass sheet 111 arranged on the outside of the vehicle cabin, a glass sheet 112 arranged inside the vehicle cabin relative to the glass sheet 111, and an intermediate film 113 arranged between the glass sheets 111 and 112, a flat harness 120 having an end 121 which is one end, an end 122 which is the other end, and an intermediate extending portion 123 between the end 121 and the end 122, wherein the end 121 and the intermediate extending portion 123 are arranged between the glass sheets 111 and 112, and the end 122 is located between or outside the glass sheets 111 and 112, and a flat harness 130 which is arranged on a main surface 112B of the glass sheet 112 and has a third end 131 which is one end, and a fourth end 132 which is the other end, wherein the fourth end 132 is connected to the end 121. Therefore, a flat harness 120 can be provided between the glass plates 111 and 112 of the laminated glass 110, and a flat harness 130 that connects to the flat harness 120 can be provided on the main surface 112B of the glass plate 112, allowing the flat harnesses 120 and 130 to be used as signal transmission lines and power transmission lines.

[0164] Therefore, it is possible to provide a vehicle window glass 100 with a flat harness that can provide a place to arrange the flat harnesses 120 and 130. In recent years, the number of electrical components mounted on vehicles has increased, resulting in a shortage of space to arrange wire harnesses and the like. However, by using the vehicle window glass 100 with a flat harness, the flat harness 120 can ensure a signal transmission line and a power transmission line.

[0165] Although exemplary vehicle window glass with a flat harness according to the present disclosure has been described above, the present disclosure is not limited to the specifically disclosed embodiments, and various modifications and variations are possible without departing from the scope of the claims.
