[0009] [Description of the embodiments of the present disclosure] First, the embodiments of the present disclosure will be listed and described.

[0010] The mounting structure of the flat wire harness according to the present disclosure is as follows.

[0011] (1) An installation structure for a flat wire harness comprising: a flat wire harness arranged on a routing surface of a target component; a fastening member provided on the flat wire harness; and a bracket to which the fastening member is fastened, wherein the flat wire harness includes a plurality of linear transmission members and a base material that keeps the plurality of linear transmission members flat, wherein the base material has an arrangement main body portion on which the plurality of linear transmission members are arranged and which is arranged on the routing surface, and an attachment portion located to the side of the arrangement main body portion and on which the fastening member is provided, wherein the bracket extends in a direction intersecting the routing surface, and the attachment portion is curved relative to the arrangement main body portion.

[0012] According to the mounting structure of the flat wire harness of (1), the bracket extends in a direction intersecting the wiring surface, and the mounting portion is curved relative to the main body portion, which makes it possible to increase the design freedom of the fastening direction of the fastening member.

[0013] (2) In the mounting structure for the flat wire harness of (1), the fastening direction of the fastening member may be aligned with the extending direction of the linear transmission member, so that a worker positioned to the side of the flat wire harness can easily visually confirm the fastened portion of the bracket when fastening the fastening member to the bracket.

[0014] (3) In the mounting structure of the flat wire harness according to (1) or (2), the flat wire harness may include a restraining member that restrains the bent portion of the mounting portion. This makes it easier to fasten the fastening member of the mounting portion to the bracket by keeping the mounting portion in a mounted state posture by the restraining member.

[0015] (4) In the mounting structure for the flat wire harness according to any one of (1) to (3), the arrangement main body may have a first arrangement portion and a second arrangement portion spaced apart from each other along a width direction of the base material, and the mounting portion may be provided between the first arrangement portion and the second arrangement portion along the width direction of the base material. This provides the mounting portion between the linear transmission members.

[0016] (5) In the mounting structure for the flat wire harness according to any one of (1) to (4), the arrangement main body has a first extending portion and a second extending portion provided at different positions from each other along the extending direction of the linear transmission member, the mounting portion is provided on a side of the first extending portion, the base material has a second mounting portion provided on a side of the second extending portion, the second mounting portion is attached via a second fastening member, a main surface of the first extending portion and a main surface of the second extending portion face in different directions from each other, and the fastening direction of the fastening member may be along the fastening direction of the second fastening member. This allows the fastening directions of two fastening members corresponding to two extending portions whose main surfaces are oriented differently from each other to be aligned.

[0017] (6) In the mounting structure for the flat wire harness according to any one of (1) to (5), the bracket may protrude from the wiring surface. In this way, the flat wire harness is attached to a member having a wiring surface, and is thereby maintained in a state of being routed on the wiring surface.

[0018] (7) In the mounting structure for the flat wire harness according to any one of (1) to (5), the mounting target member may include a first member having the routing surface and a second member that is a member different from the first member and is located around the routing surface, and the bracket may extend from the second member. In this way, the flat wire harness is maintained in a state of being routed on the routing surface by being mounted to the second member located around the first member having the routing surface. Even when a bracket cannot be provided on the first member having the routing surface, the flat wire harness can be mounted using the second member located around the first member.

[0019] (8) The flat wire harness with fastening members of the present disclosure includes a flat wire harness including a plurality of linear transmission members and a base material that keeps the plurality of linear transmission members flat, and fastening members provided on the flat wire harness, the base material having an arrangement main body portion on which the plurality of linear transmission members are arranged and which is arranged on a routing surface of a routing target of the flat wire harness, and an attachment portion located on the side of the arrangement main body portion and on which the fastening members are provided, the attachment portion being curved with respect to the arrangement main body portion, and the fastening direction of the fastening members being along the extending direction of the linear transmission members, making it easy for a worker positioned on the side of the flat wire harness to visually confirm a fastened portion of a fastening partner when fastening the fastening member to the fastening partner.

[0020] [Details of the embodiment of the present disclosure] Specific examples of the mounting structure of the flat wire harness of the present disclosure will be described below with reference to the drawings. Note that the present disclosure is not limited to these examples, but is defined by the claims, and is intended to include all modifications within the meaning and scope of the claims.

[0021] [Embodiment 1] Hereinafter, the mounting structure for a flat wire harness according to the first embodiment will be described. Fig. 1 is a schematic plan view showing a mounting structure 10 for a flat wire harness according to the first embodiment. Fig. 2 is a schematic cross-sectional view taken along line II-II in Fig. 1. Fig. 3 is an enlarged view of an area A1 in Fig. 2. Fig. 4 is an exploded perspective view showing the mounting structure 10 for a flat wire harness according to the first embodiment.

[0022] The mounting structure 10 for a flat wire harness includes a flat wire harness 20, a fastening member 40, and a bracket 14. The flat wire harness 20 is routed on a routing surface 13 of a mounting target member 11. The fastening member 40 is provided on the flat wire harness 20. The fastening member 40 is fastened to the bracket 14, thereby maintaining the flat wire harness 20 in a state of being routed on the routing surface 13.

[0023] The mounting target member 11 is, for example, a reinforcement 11 in a vehicle. The vehicle is, for example, an automobile. In the vehicle, the location of the reinforcement 11 is not particularly limited and can be set appropriately. Here, the reinforcement 11 is described as being disposed inside the instrument panel of the vehicle. Such a reinforcement 11 is also called an instrument panel reinforcement. The instrument panel is located in front of the driver's seat and the passenger seat. Instruments such as a speedometer are incorporated in the instrument panel. The instrument panel usually has an upper panel located above the reinforcement 11 and a lower panel located behind the reinforcement 11 with respect to the forward direction of the vehicle. In the space inside the instrument panel, a dash panel is located in front of the reinforcement 11. The dash panel separates the space inside the instrument panel from the engine room. Therefore, the reinforcement 11 is surrounded by the upper panel, the lower panel, and the dash panel.

[0024] The reinforcement 11 supports a steering shaft (not shown) and the like. One end of the steering shaft protrudes rearward from the instrument panel and supports a steering wheel (not shown). The reinforcement 11 includes a reinforcement body 12. Here, the reinforcement 11 also includes a bracket 14.

[0025] The reinforcement body 12 is formed in a tubular shape, such as a cylindrical shape or a square tubular shape. When the reinforcement 11 is arranged in an instrument panel, the reinforcement body 12 extends in the left-right direction (vehicle width direction) of the vehicle. One longitudinal end of the reinforcement body 12 is connected to the left wall of the vehicle body, and the other end is connected to the right wall of the vehicle body. The outer surface of the reinforcement body 12 is used as a routing surface 13 on which the flat wire harness 20 is routed. A bracket 14 protrudes from the routing surface 13.

[0026] The bracket 14 is attached to the outer periphery of the reinforcement body 12. The bracket 14 protrudes from the outer surface of the reinforcement body 12 in a direction intersecting with the longitudinal direction of the reinforcement body 12. In the example shown in FIG. 2, the bracket 14 extends vertically from both sides of the reinforcement body 12 along the horizontal direction (front-rear direction). The bracket 14 may extend in a tangential direction of the circular reinforcement body 12, or in a direction intersecting with the tangential direction. The bracket 14 is provided at a plurality of positions spaced apart along the longitudinal direction of the reinforcement body 12. Here, the reinforcement body 12 and the bracket 14 are both made of metal and are integrated by welding. However, the manner of attachment of the bracket 14 and the reinforcement body 12 is not limited to welding, and can be set appropriately. The bracket 14 may also be made of resin.

[0027] The bracket 14 has a mounting hole 15 for mounting the flat wire harness 20. The mounting hole 15 is located at one end of the bracket 14, on one side of the reinforcement body 12.

[0028] The flat wire harness 20 is formed flat. The flat wire harness 20 extends along the longitudinal direction of the reinforcement 11. The flat wire harness 20 includes a plurality of linear transmission members 22 and a base material 25. The base material 25 holds the plurality of linear transmission members 22 in a flat lined state. In the flat wire harness 20, the plurality of linear transmission members 22 extend along the reinforcement body 12.

[0029] The linear transmission member 22 may be a linear member that transmits electricity or light. The linear transmission member 22 is, for example, an electric wire that transmits electricity or an optical fiber that transmits light. Here, the linear transmission member 22 is described as being an electric wire 22. Each of the multiple electric wires 22 is a coated electric wire. The coated electric wire has a conductor core wire 23 and a coating layer 24 that covers the conductor core wire 23.

[0030] In the flat wire harness 20, the extension direction of the multiple electric wires 22 is the longitudinal direction of the flat wire harness 20. The parallel direction of the multiple electric wires 22 is the width direction of the flat wire harness 20. The lamination direction of the electric wires 22 and the base material 25 is the thickness direction of the flat wire harness 20. In the flat wire harness 20, the dimension in the extension direction and the dimension in the width direction are larger than the dimension in the thickness direction. The width dimension of the flat wire harness 20 may be, for example, the same as or larger than the width dimension of the reinforcement body 12. In the flat wire harness 20, an edge on one side along the width direction is defined as a first edge, and an edge on the other side is defined as a second edge.

[0031] The parallel structure of the multiple electric wires 22 is not particularly limited as long as they are arranged flat. For example, the multiple electric wires 22 may be arranged in a scattered state on the main surface of the base material 25. The multiple electric wires 22 may be held in a line or in a stacked line. In each row, adjacent electric wires 22 may be separated from each other as shown in FIG. 2. In each row, adjacent electric wires 22 may be in contact with each other.

[0032] The electric wires 22 may be bundled together and disposed on the main surface of the base material 25. In this case, the electric wires 22 may be divided into a plurality of groups. Specifically, the electric wires 22 are bundled together in groups to form a plurality of bundles. The bundles are arranged along the main surface. This makes it easier for the electric wires 22 to be kept flat.

[0033] Here, the base material 25 is formed in a sheet shape. The structure for holding the plurality of electric wires 22 in a state in which they are arranged flat on the base material 25 is not particularly limited. For example, each of the plurality of electric wires 22 may be fixed to the base material 25 by welding (including ultrasonic welding, heat and pressure welding, hot air welding, high frequency welding, or welding by a solvent), an adhesive, a pressure sensitive adhesive, or the like. In this case, the plurality of electric wires 22 are more likely to be kept in a flat state. Also, each of the plurality of electric wires 22 may be fixed to the base material 25 by a sewing thread. Also, the plurality of electric wires 22 and the base material 25 may be bound by a binding member wound around the plurality of electric wires 22 and the base material 25. The binding member may be, for example, a cable tie (also called a cable tie) or an adhesive tape.

[0034] Here, the flat wire harness 20 has one layer. Here, if a plurality of electric wires 22 held by one base material 25 is considered to be one wiring body, the flat wire harness 20 may have a laminated structure in which a plurality of wiring bodies are laminated. The configuration for holding the laminated structure of the plurality of wiring bodies may be any configuration, and for example, the base materials 25 of the plurality of wiring bodies may be connected to each other to hold the laminated structure. The number of layers of the wiring bodies is not particularly limited, and may be two layers, three layers, or four or more layers.

[0035] The base material 25 has a first surface and a second surface facing in opposite directions. Here, the multiple electric wires 22 are arranged only on the first surface of the base material 25. No electric wires 22 are arranged on the second surface. The multiple electric wires 22 may be arranged separately on the first surface and the second surface of the base material 25.

[0036] The base material 25 has an arrangement main body portion 26 and an attachment portion 28. A plurality of linear transmission members 22 are arranged in the arrangement main body portion 26. The arrangement main body portion 26 is arranged on the arrangement surface 13. The attachment portion 28 is located on the side of the arrangement main body portion 26. A fastening member 40 is provided on the attachment portion 28. In this embodiment, the attachment portion 28 protrudes outward from the outer edge of the arrangement main body portion 26. The attachment portion 28 is located at a first edge portion and a second edge portion of the flat wire harness 20, respectively. The attachment portion 28 is partially provided on the arrangement main body portion 26 along the extension direction of the electric wires 22.

[0037] In the flat wire harness 20, the electric wires 22 are fixed to a base material 25 that covers one side, and portions of the electric wires 22 that face the opposite side to the base material 25 are exposed. The flat wire harness 20 may include a cover that covers the electric wires 22 from the opposite side to the base material 25. The cover may be fixed to the base material 25 and not fixed to the electric wires 22. Even if a portion is provided where the cover and the electric wires 22 contact each other, the cover and the electric wires 22 may not be fixed at the contact portion. When wiring bodies are stacked, the base material 25 of one wiring body can function as a cover for another wiring body.

[0038] The flat wire harness 20 is supported by the reinforcement 11 in a position in which the width direction of the flat wire harness 20 is along the horizontal direction (here, the front-rear direction). The flat wire harness 20 may be supported in a position in which the width direction of the flat wire harness 20 is along a direction inclined with respect to the horizontal direction.

[0039] The flat wire harness 20 is supported in a position extending straight in the width direction. For example, the flat wire harness 20 may have a first rigidity that allows the first edge to maintain a position extending straight in the width direction without sagging even in a state in which the second edge is supported and the first edge is a free end and extends horizontally. A part of the flat wire harness 20 along the width direction may be bent in the thickness direction relative to another part. The flat wire harness 20 may have a second rigidity that bends the first edge to sag vertically downward in a state in which the second edge is supported and the first edge is a free end and extends horizontally. Each wiring body in the flat wire harness 20 may have a second rigidity by itself, and the flat wire harness 20 in which a plurality of wiring bodies are stacked and integrated may have a first rigidity.

[0040] The bracket 14 extends in a direction intersecting with the routing surface 13. The attachment portion 28 is provided so as to be curved with respect to the arrangement main body portion 26. In the example shown in Fig. 2, on the first surface side of the base material 25, the extension direction of the bracket 14 is set so that the extension direction of the attachment portion 28 and the extension direction of the arrangement main body portion 26 are perpendicular to each other.

[0041] 2, the reinforcement 11 includes a reinforcement body 12 whose outer circumferential surface in cross section is circular, and the flat wire harness 20 is attached in a linear manner extending from one end to the other end in the width direction of the flat wire harness 20. In other words, the flat wire harness 20 extends linearly along the width direction and is not bent so as to follow the circular outer circumferential surface of the reinforcement body 12. The flat wire harness 20 may be bent so as to follow the circular outer circumferential surface of the reinforcement body 12.

[0042] 3, a snap fastener is provided as an example of the fastening member 40. The snap fastener includes a male snap fastener 42 and a female snap fastener 44. The male snap fastener 42 and the female snap fastener 44 are attached to each other by fitting an engagement protrusion of the male snap fastener 42 into an engagement recess of the female snap fastener 44. The engagement between the engagement protrusion and the engagement recess is, for example, an engagement using elastic deformation, and may be capable of repeated attachment and detachment.

[0043] In FIG. 3, the male snap fastener 42 and the female snap fastener 44 are similar to the male snap fastener and the female snap fastener described in the above-mentioned Patent Document 1. In each of the figures other than FIG. 3, the fastening member 40 is illustrated in a simplified form. The male snap fastener 42 is attached to the mounting portion 28, and the female snap fastener 44 is attached to the peripheral portion of the mounting hole 15 of the bracket 14. The male snap fastener 42 is composed of a first member and a second member that combine together while holding the mounting portion 28 in the thickness direction. Similarly, the female snap fastener 44 is composed of a first member and a second member that combine together while holding the peripheral portion of the mounting hole 15 of the bracket 14 in the thickness direction. The combination of the first member and the second member in each snap fastener 42, 44 may be performed by using a crimping deformation or an elastic deformation. The male snap fastener 42 and the female snap fastener 44 are not limited to those described above, and other well-known fasteners may be used.

[0044] The configuration of the fastening member 40 is not limited to that described above. For example, the male snap fastener 42 may be attached to the periphery of the mounting hole 15 of the bracket 14, and the female snap fastener 44 may be attached to the mounting portion 28. Also, for example, the female snap fastener 44 may be omitted, and the male snap fastener 42 provided on the mounting portion 28 may be directly fastened to the mounting hole 15 of the bracket 14. Also, the fastening member 40 may be a member other than a snap fastener, such as a rivet or a bolt.

[0045] The flat wire harness 20 includes an angle restraint member 30 that restrains the bent portion of the mounting portion 28. The rigidity of the angle restraint member 30 may be higher than the rigidity of the base material 25. The angle restraint member 30 may be made of, for example, metal or hard resin. The angle restraint member 30 is attached to the base material 25. By providing the angle restraint member 30, the bent portion of the base material 25 is maintained at a predetermined bending angle. The manner in which the angle restraint member 30 is fixed to the base material 25 is not particularly limited and can be set as appropriate.

[0046] The angle constraint member 30 has a first portion on the arrangement main body portion 26 side and a second portion on the attachment portion 28 side. The angle constraint member 30 is bent at a predetermined bending angle between the first portion and the second portion. The angle constraint member 30 has a rigidity capable of holding a bent shape between the first portion and the second portion. For example, the first portion is fixed to the arrangement main body portion 26, and the second portion is fixed to the attachment portion 28. As a result, the bent portion between the arrangement main body portion 26 and the attachment portion 28 of the base material 25 is held at the bending angle of the angle constraint member 30. In the example shown in FIG. 3, the angle constraint member 30 is bent at 90 degrees between the first portion and the second portion.

[0047] The second portion does not reach the portion of the mounting portion 28 where the fastening member 40 is provided. The second portion may reach the portion where the fastening member 40 is provided. The fastening member 40 may be provided in the second portion. The angle restraint member 30 is provided on a first surface of the base material 25. The angle restraint member 30 may be provided on a second surface of the base material 25.

[0048] The flat wire harness 20 in Fig. 4 can be regarded as a flat wire harness 20 with a fastening member 40. The flat wire harness 20 with a fastening member 40 includes the flat wire harness 20 and a fastening member 40 provided on the flat wire harness 20. The flat wire harness 20 includes a plurality of linear transmission members 22 and a base material 25 that keeps the plurality of linear transmission members 22 flat. The base material 25 has an arrangement main body portion 26 on which the plurality of linear transmission members 22 are arranged and which is routed on the arrangement surface 13, and an attachment portion 28 located on the side of the arrangement main body portion 26 and on which the fastening member 40 is provided, and the attachment portion 28 is provided bent with respect to the arrangement main body portion 26.

[0049] <Effects, etc.> According to the mounting structure 10 for the flat wire harness configured as described above, the bracket 14 extends in a direction intersecting with the wiring surface 13, and the mounting portion 28 is bent with respect to the arrangement body portion 26, so that it is possible to increase the degree of freedom in designing the fastening direction of the fastening member 40. For example, even if the positional relationship between the flat wire harness 20 and the mounting target member 11 is not on the same plane, on a circumference with the same curvature, or on a tangent to the circumference, the fastening member 40 can be provided. In addition, even if there is no space to extend the bracket 14 outside the wiring surface 13 along the width direction of the flat wire harness 20, the fastening member 40 can be fastened by extending the bracket 14 in a direction intersecting with the wiring surface 13.

[0050] Furthermore, when the flat wire harness 20 includes an angle restraint member 30 that restrains the bent portion of the mounting portion 28, the angle restraint member 30 maintains the mounting portion 28 in the mounted state posture, making it easier to fasten the fastening member 40 of the mounting portion 28 to the bracket 14.

[0051] Also, the bracket 14 protrudes from the wiring surface 13. As a result, the flat wire harness 20 is attached to a member having the wiring surface 13, and is thereby maintained in a state of being routed on the wiring surface 13.

[0052] [Modification of the first embodiment] Modifications of the mounting structure 10 for a flat wire harness according to the first embodiment will be described below. In the following descriptions of the modifications and the first embodiment, the same components as those described above will be denoted by the same reference numerals, and the description thereof will be omitted.

[0053] Fig. 5 is a schematic cross-sectional view showing a first modified example of the flat wire harness mounting structure 10. In the flat wire harness mounting structure 10A shown in Fig. 5, the extending direction of the bracket 14A in the reinforcement 11A is different from the extending direction of the bracket 14 in the reinforcement 11. In the example shown in Fig. 5, the extending direction of the bracket 14A is set so that the angle between the extending direction of the mounting portion 28 and the extending direction of the arrangement main body portion 26 on the first surface side of the base material 25 is an obtuse angle.

[0054] Fig. 6 is a schematic cross-sectional view showing a second modified example of the mounting structure 10 for a flat wire harness. In the mounting structure 10B for a flat wire harness shown in Fig. 6, the extending direction of the bracket 14B in the reinforcement 11B is also different from the extending direction of the bracket 14 in the reinforcement 11. The bracket 14B extends downward from the wiring surface 13. In the example shown in Fig. 6, the extending direction of the bracket 14B is set so that the angle between the extending direction of the mounting portion 28 and the extending direction of the arrangement main body portion 26 on the first surface side of the base material 25 is larger than 180 degrees.

[0055] Fig. 7 is a schematic cross-sectional view showing a third modified example of the mounting structure 10 for a flat wire harness. In the mounting structure 10C for a flat wire harness shown in Fig. 7, the extending direction of the bracket 14C in the reinforcement 11C is also different from the extending direction of the bracket 14 in the reinforcement 11. The bracket 14C extends downward from the wiring surface 13. In the example shown in Fig. 7, the extending direction of the bracket 14C is set so that the angle between the extending direction of the mounting portion 28 and the extending direction of the arrangement main body portion 26 is 270 degrees on the first surface side of the base material 25.

[0056] The angle of the bracket with respect to the reinforcement 11 may be set to an angle other than the angles of the brackets 14, 14A, 14B, and 14C described above.

[0057] Fig. 8 is a schematic cross-sectional view showing a fourth modified example of the mounting structure 10 for a flat wire harness. In a reinforcement 11D of a mounting structure 10D for a flat wire harness shown in Fig. 8, a bracket 14 is provided only on one side of the reinforcement body 12. In a corresponding flat wire harness 20D, a mounting portion 28 is provided only on one side of the arrangement main body portion 26. In the example shown in Fig. 8, the angle of the bracket provided only on one side of the reinforcement body 12 is set to the angle of the bracket 14, but it may be set to the angle of the other brackets 14A, 14B, and 14C.

[0058] Fig. 9 is a schematic cross-sectional view showing a fifth modified example of the mounting structure 10 for a flat wire harness. The shape of a reinforcement 11E of a mounting structure 10E for a flat wire harness shown in Fig. 9 is different from the shape of the reinforcement 11. In the reinforcement 11E, a bracket 14 provided on one side of the reinforcement body 12 and a bracket 14B provided on the other side are asymmetrical with respect to a line passing through the center of the reinforcement body 12. In the example shown in Fig. 9, the brackets on both sides of the reinforcement body 12 are a combination of the bracket 14 and the bracket 14B, but other combinations may be used.

[0059] [Embodiment 2] A description will now be given of a mounting structure for a flat wire harness according to embodiment 2. Fig. 10 is a schematic cross-sectional view showing a mounting structure 110 for a flat wire harness according to embodiment 2.

[0060] In the examples described above, the bracket 14 is provided on a member having the routing surface 13, but in this embodiment, the bracket 118 is provided on a member other than the member having the routing surface 13. The attachment target member includes a first member 111 having the routing surface 13 and a second member 116 that is a member other than the first member 111 and is located around the routing surface 13. The bracket 118 extends from the second member 116. As a result, the flat wire harness 20 is attached to the second member 116 located around the first member 111 having the routing surface 13, so that the flat wire harness 20 is maintained in a state of being routed on the routing surface 13. Even when the bracket 14 cannot be provided on the first member 111 having the routing surface 13, the flat wire harness 20 can be attached using the second member 116 located around the periphery.

[0061] Here, the first member 111 is the reinforcement 111. The reinforcement 111 has the same configuration as the above-mentioned reinforcement 11 except that the bracket 14 is not provided.

[0062] The second member 116 is a member located around the reinforcement 111, and is, for example, a duct 116. The duct 116 is a tubular member that connects between the main body of the vehicle-mounted air conditioner and the air outlet. The duct 116 has a duct main body 117 through which air from the main body of the vehicle-mounted air conditioner passes. The bracket 118 protrudes outward from the outer periphery of the duct main body 117 of the duct 116.

[0063] In the example shown in Fig. 10, a duct body 117 of a duct 116 extends so as to intersect with the reinforcement 111. In the example shown in Fig. 10, brackets 118 on both sides of the reinforcement body 12 are provided on the duct 116. A bracket on one side of the reinforcement body 12 may be provided on the reinforcement, and a bracket on the other side may be provided on the duct.

[0064] [Embodiment 3] The mounting structure for a flat wire harness according to the third embodiment will be described. Fig. 11 is a schematic plan view showing a mounting structure 210 for a flat wire harness according to the third embodiment. Fig. 12 is a schematic cross-sectional view taken along line XI-XI in Fig. 11. Fig. 13 is an exploded perspective view showing the mounting structure 210 for a flat wire harness according to the third embodiment.

[0065] In the mounting structure 210 for the flat wire harness, the positional relationship between the arrangement main body 226 and the mounting portion 228 in the base material 225 is different from the positional relationship between the arrangement main body 26 and the mounting portion 28 in the above-mentioned base material 25. The arrangement main body 226 has a first arrangement portion 227A and a second arrangement portion 227B that are provided apart from each other along the width direction of the base material 225. The mounting portion 228 is provided between the first arrangement portion 227A and the second arrangement portion 227B along the width direction of the base material 225. As a result, the mounting portion 228 is provided between the electric wires 22 along the width direction of the base material 225.

[0066] The mounting portion 228 is formed by cutting and raising a part of the base material 225. A through hole 229 is formed in the base material 225 at the portion where the mounting portion 228 is cut and raised. The bracket 214 protrudes from the reinforcement body 12 in the reinforcement 211 and passes through the through hole 229. The thickness direction of the bracket 214 in the reinforcement 211 is aligned with the longitudinal direction of the reinforcement body 12.

[0067] Furthermore, in the mounting structure 210 for the flat wire harness, the fastening direction of the fastening member 40 is different from the fastening direction of the fastening member 40 in the mounting structure 10 for the flat wire harness. Here, the fastening direction of the fastening member 40 is along the extending direction of the electric wires 22. A fold for raising the mounting portion 228A is provided so as to extend along the width direction of the base material 225. This makes it easy for a worker positioned to the side of the flat wire harness 220 to visually confirm the fastened portion of the bracket 214 when fastening the fastening member 40 to the bracket 214.

[0068] [Modification of the third embodiment] FIG. 14 is an exploded perspective view showing a modified example of the mounting structure 210 of the flat wire harness according to the third embodiment. In the mounting structure 210A of the flat wire harness shown in FIG. 14, the mounting portion 228A of the flat wire harness 220A is also provided between the first arrangement portion 227A and the second arrangement portion 227B along the width direction of the base material 225A. In the mounting structure 210A of the flat wire harness, a fold for raising the mounting portion 228A is provided so as to extend along the extending direction of the electric wires 22. As a result, in the mounting structure 210A of the flat wire harness, the fastening direction of the fastening member 40 is along the width direction of the base material 225. The width direction of the bracket 214A in the reinforcement 211A is along the longitudinal direction of the reinforcement body 12.

[0069] [Embodiment 4] The mounting structure for a flat wire harness according to the fourth embodiment will be described. Fig. 15 is a schematic plan view showing a mounting structure 310 for a flat wire harness according to the fourth embodiment. Fig. 16 is a side view showing a mounting structure 310 for a flat wire harness according to the fourth embodiment. Fig. 17 is a schematic cross-sectional view taken along line XVII-XVII in Fig. 15. The schematic cross-sectional view taken along line II-II in Fig. 15 is similar to Fig. 2.

[0070] In the mounting structure 310 for the flat wire harness, the extending direction of the arrangement main body 326 of the flat wire harness 320 is different from the extending direction of the arrangement main body 26 of the flat wire harness 20. The arrangement main body 326 has a first extending portion 326A and a second extending portion 326B provided at different positions from each other along the extending direction of the electric wires 22.

[0071] The main surface of the first extension portion 326A and the main surface of the second extension portion 326B face in different directions. Here, the main surface of the first extension portion 326A faces upward, and the main surface of the second extension portion 326B faces horizontally (here, rearward). The flat wire harness 320 is bent in a three-dimensional direction between the first extension portion 326A and the second extension portion 326B. For example, the flat wire harness 320 is bent in a three-dimensional direction between the first extension portion 326A and the second extension portion 326B to avoid the obstacle OB. The first extension portion 326A and the second extension portion 326B are in a twisted positional relationship.

[0072] The mounting portion 28 is provided on the side of the first extending portion 326A. The base material 325 has a second mounting portion 328 provided on the side of the second extending portion 326B. The second mounting portion 328 is attached via a second fastening member 340. The fastening direction of the fastening member 40 is aligned with the fastening direction of the second fastening member 340. This allows the fastening directions of the two fastening members 40, 340 corresponding to the two extending portions 326A, 326B whose principal surfaces are oriented differently from each other to be aligned with each other.

[0073] The second fastening member 340 is fastened to the second bracket 314. The second bracket 314 is provided on the reinforcement 311. The second bracket 314 extends tangentially from the reinforcement body 12, and the second mounting portion 328 extends straight from the outer side of the second extension portion 326B without bending relative to the second extension portion 326B. The second mounting portion 328 may extend from the outer side of the second extension portion 326B while bending relative to the second extension portion 326B.

[0074] The fastening partner of the second fastening member 340 may be the reinforcement body 12, or may be a bracket provided on a member other than the reinforcement 311. The fastening direction of the second fastening member 340 may be a direction perpendicular to the main surface of the first extending portion 326A.

[0075] The configurations described in the above embodiments and modifications can be combined as appropriate as long as they are not mutually inconsistent.

[0076] For example, a portion of the flat wire harness 20 along the extension direction may be fastened to a bracket 14 provided on the reinforcement body 12, and another portion may be fastened to a bracket 14 provided on the duct body 117.

[0077] For example, a configuration in which the mounting portion 28 is provided on the outer edge of the arrangement main body portion 26 as in embodiment 1 may be combined with a configuration in which the fastening direction of the fastening member 40 is along the extension direction of the linear transmission member 22 as in embodiment 3.
