[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) A mounting structure for a flat wire harness in which a flat wire harness is mounted to a reinforcement provided in a vehicle, the flat wire harness comprising: a first arm portion mounted to the reinforcement via a first mounting portion; a hinge portion connected to the first arm portion and having a rotation axis along the longitudinal direction of the reinforcement; and a second arm portion connected to the hinge portion on the opposite side to the first arm portion; a flat wire harness provided to move integrally with the second arm portion when the first arm portion and the second arm portion rotate relatively around the rotation axis; The mounting structure for a flat wire harness includes a second mounting portion arranged to move integrally with the flat wire harness, and a mounting receiver arranged to rotate relative to the second mounting portion when the first arm portion and the second arm portion rotate relatively around the rotation axis, and to which the second mounting portion is attached, wherein the second mounting portion is attached to the mounting receiver at a position separated from the first mounting portion along a direction intersecting the longitudinal direction of the reinforcement, and the flat wire harness is maintained in a mounting position arranged along the reinforcement.

[0012] According to the mounting structure for the flat wire harness of (1), when the first mounting portion is mounted on the reinforcement and the second mounting portion is not mounted on the mounting receiving portion, the hinge portion is rotated to guide the second mounting portion to the mounting receiving portion and to place the flat wire harness in a mounting position along the reinforcement. As a result, even if the mounting receiving portion is in a position that is difficult for a worker to see because of the flat wire harness when the flat wire harness is in the mounting position, the second mounting portion can be easily moved to the mounting receiving portion.

[0013] (2) In the mounting structure for the flat wire harness of (1), a plurality of pairs of the second mounting portion and the mounting receiving portion may be provided apart from each other along the longitudinal direction of the reinforcement, whereby the second mounting portions at a plurality of locations can be guided collectively along the longitudinal direction of the reinforcement.

[0014] (3) In the mounting structure for the flat wire harness of (2), a portion of the flat wire harness extending between the plurality of sets of the second mounting portions and the mounting receivers may be a straight path, and the hinge parts may be provided at positions corresponding to the plurality of sets of the second mounting portions and the mounting receivers, respectively. This allows the flat wire harness, which rotates together with the second arm portions, to be firmly held by the plurality of hinge parts.

[0015] (4) In the mounting structure of the flat wire harness of (2), a portion of the flat wire harness extending between the second mounting portions and the mounting receivers of a first set and the second mounting portions and the mounting receivers of a second set may be a bending path, and the hinge part may be provided at a position corresponding to the second mounting portions and the mounting receivers of the first set, and the hinge part may not be provided at a position corresponding to the second mounting portions and the mounting receivers of the first set. This makes it possible to guide a plurality of second mounting portions collectively to the corresponding mounting receivers even when a portion of the flat wire harness that rotates together with the hinge part includes a bending path.

[0016] (5) In the mounting structure for a flat wire harness according to any one of (1) to (4), the reinforcement may include a reinforcement body having a circular outer circumferential surface in cross section, and the mounting posture of the flat wire harness may be a posture in which the flat wire harness extends linearly from one end to the other end in the width direction of the flat wire harness. In this way, the flat wire harness is mounted in a posture in which it is not wound around the reinforcement body.

[0017] (6) In the mounting structure for the flat wire harness of (5), the reinforcement may include a base plate portion attached to an outer periphery of the reinforcement body, the first mounting portion and the second mounting portion are attached to the base plate portion, and the flat wire harness may be spread out in a planar shape along the base plate portion. This makes it easier to maintain the flat wire harness in a planarly spread state.

[0018] In the mounting structure for the flat wire harness of (7) and (5), the first mounting portion may be attached to the reinforcement body, and the mounting receiving portion may be provided on the first arm portion. This allows the flat wire harness to be kept in a flat, expanded state by the hinge part without providing a base plate portion. In addition, since there is no need to provide a base plate portion, an increase in the number of parts can be suppressed.

[0019] (8) In the mounting structure for the flat wire harness according to any one of (1) to (7), the second mounting portion may be provided on the second arm portion. This allows the second mounting portion to be firmly held on the second arm portion, and makes it easier to maintain a predetermined dimension from the hinge portion to the second mounting portion regardless of the rigidity of the flat wire harness.

[0020] (9) In the mounting structure for the flat wire harness according to any one of (1) to (7), the second mounting portion may be provided on the flat wire harness, thereby making it possible to shorten the second arm portion.

[0021] [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.

[0022] [Embodiment 1] Hereinafter, the mounting structure for a flat wire harness according to the first embodiment will be described. Fig. 1 is a plan view showing a mounting structure 10 for a flat wire harness according to the first embodiment. Fig. 2 is a cross-sectional view taken along line II-II in Fig. 1. Fig. 3 is a plan view illustrating how the flat wire harness 20 is mounted. Fig. 4 is a cross-sectional view illustrating how the flat wire harness 20 is mounted.

[0023] In the mounting structure 10 for the flat wire harness, the flat wire harness 20 is mounted to 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 includes a base plate portion 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 disposed in an instrument panel, the reinforcement body 12 extends in the left-right direction (vehicle width direction) of the vehicle. One end of the reinforcement body 12 in the longitudinal direction is connected to the left wall of the vehicle body, and the other end is connected to the right wall of the vehicle body.

[0026] The base plate portion 14 is attached to the outer periphery of the reinforcement body 12. The base plate portion 14 protrudes from the outer surface of the reinforcement body 12 in a direction intersecting the longitudinal direction of the reinforcement body 12. In the example shown in FIG. 2, the base plate portion 14 extends horizontally on both sides from the reinforcement body 12. The base plate portion 14 extends in a tangential direction of the circular reinforcement body 12. The base plate portion 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 base plate portion 14 are both made of metal and are integrated by welding. However, the manner of attachment of the base plate portion 14 and the reinforcement body 12 is not limited to welding and can be set appropriately. The base plate portion 14 may also be made of resin.

[0027] A flat wire harness 20 is attached to the base plate portion 14. In the example shown in Fig. 2, two mounting holes 15, 16 for attaching the flat wire harness 20 are formed in the base plate portion 14. The mounting hole 15 is located at one end of the base plate portion 14, on one side of the reinforcement body 12. The mounting hole 16 is located at the other end of the base plate portion 14, on the other 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, the edge on one side along the width direction is a first edge 26, and the edge on the other side is a second edge 27.

[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. 3. In each row, adjacent electric wires 22 may be in contact with each other.

[0032] The plurality of electric wires 22 may be arranged on the main surface of the base material 25 in a bundled state. In this case, the plurality of electric wires 22 may be divided into a plurality of groups. Specifically, the plurality of electric wires 22 are bundled separately for each of the plurality of groups into a plurality of bundles. The plurality of bundles are arranged along the main surface. This makes it easy to keep the plurality of electric wires 22 in a flat state.

[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 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, it is easier to keep the plurality of electric wires 22 in a flat state. Also, each of the plurality of electric wires 22 may be fixed to the base material 25 by 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, a plurality of wiring bodies 21 are stacked to form the flat wire harness 20. In each wiring body 21, a plurality of electric wires 22 are held by a base material 25. In the example shown in Fig. 3, the number of layers of the wiring body 21 is three, but it may be two or four or more layers. In the flat wire harness 20, the wiring body 21 may be only one layer without being stacked.

[0035] The base material 25 has a first surface and a second surface facing in opposite directions. Here, when the wiring body 21 is not formed into a laminate but exists independently, 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 configuration for maintaining the stacked state of the multiple wiring bodies 21 is not particularly limited and can be set as appropriate. For example, the stacked state of the multiple wiring bodies 21 may be maintained by fixing side edges of the multiple base materials 25 to each other by welding, adhesive, pressure sensitive adhesive, etc. Also, for example, the stacked state of the multiple wiring bodies 21 may be maintained by a bundling member wrapped around the multiple wiring bodies 21.

[0037] In the flat wire harness 20, the electric wires 22 in the wiring body 21 are fixed to one base material 25, and when the wiring body 21 is not laminated but exists alone, the portions of the electric wires 22 facing the opposite side to the base material 25 are exposed. By laminating a plurality of wiring bodies 21, the electric wires 22 of the wiring body 21 in the intermediate layer are covered by the base material 25 of the wiring body 21 laminated on one side or the other side. Even if the electric wires 22 of the first wiring body are in contact with the base material 25 of the second wiring body, the contact portion is not fixed.

[0038] In the flat wire harness 20, the cover 28 is provided on the wiring body 21 of the first layer, which is the surface layer. The cover 28 covers the electric wires 22 from the opposite side to the base material 25. This prevents the electric wires 22 from being exposed on the main surface of the flat wire harness 20. Even if the cover 28 is not provided separately from the base material 25, the wiring body 21 of the first layer may be oriented so that the electric wires 22 face the wiring body 21 of the second layer, thereby preventing the electric wires 22 from being exposed on the main surface of the flat wire harness 20 by the base material 25. In the flat wire harness 20, the cover 28 may not be provided, and the electric wires 22 of the wiring body 21 of the first layer may be exposed on the main surface of the flat wire harness 20. The side edge of the cover 28 may be fixed to the side edge of the base material 25. Even if the electric wires 22 of the wiring body 21 of the first layer are in contact with the cover 28, the contact portion may not be fixed.

[0039] 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.

[0040] 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 26 to maintain a position extending straight in the width direction without sagging even in a state in which the second edge 27 is supported and the first edge 26 is a free end and extends in the horizontal direction. 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 26 to sag vertically downward in a state in which the second edge 27 is supported and the first edge 26 is a free end and extends in the horizontal direction. Each wiring body 21 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 21 are stacked and integrated may have a first rigidity.

[0041] In the mounting structure 10 for the flat wire harness, the flat wire harness 20 is mounted to the reinforcement 11 by the hinge part 30, the first mounting portion 40, the second mounting portion 50, and the mounting receiving portion 16.

[0042] The hinge component 30 includes a first arm portion 31, a hinge portion 32, and a second arm portion 33. The first arm portion 31 is attached to the reinforcement 11 via a first attachment portion 40. The hinge portion 32 is connected to the first arm portion 31. The hinge portion 32 has a rotation axis along the longitudinal direction of the reinforcement 11. The second arm portion 33 is connected to the hinge portion 32 on the opposite side to the first arm portion 31. The first arm portion 31 and the second arm portion 33 are relatively rotatable via the hinge portion 32.

[0043] In the hinge part 30, the first arm part 31, the second arm part 33, and the hinge part 32 may be integrally molded using a material such as resin so that the hinge part 32 is thinner than the first arm part 31 and the second arm part 33. Such a hinge part 30 is also called an integral hinge or a living hinge. The hinge part 30 may be provided so that the first arm part 31 and the second arm part 33, which are separate parts, are connected by a rotation axis. Such a hinge part 30 may be made of resin or metal. In such a hinge part 30, the shaft part and the bearing part serving as the rotation axis may be integrally molded with the first arm part 31 and the second arm part 33, or the bearing part may be provided on the first arm part 31 and the second arm part 33, respectively, and a pin serving as the shaft part may be provided separately from the first arm part 31 and the second arm part 33.

[0044] The first mounting portion 40 is a portion that mounts the first arm portion 31 to the reinforcement 11. When the first arm portion 31 and the second arm portion 33 rotate relatively around the rotation axis of the hinge portion 32, the first mounting portion 40 is provided to move integrally with the first arm portion 31, and the flat wire harness 20 is provided to move integrally with the second arm portion 33.

[0045] The second mounting portion 50 is attached to the mounting receiver 16 at a position separated from the first mounting portion 40 along a direction intersecting the longitudinal direction of the reinforcement 11. The second mounting portion 50 is provided so as to move integrally with the flat wire harness 20, and the mounting receiver 16 is provided so as to rotate relative to the second mounting portion 50, when the first arm portion 31 and the second arm portion 33 rotate relatively around the rotation axis.

[0046] As shown in FIG. 2, in a state where the hinge part 30 is attached to the reinforcement 11 via the first attachment part 40 and the second attachment part 50 is attached to the attachment receiving part 16, the first arm part 31 and the second arm part 33 cannot rotate relatively via the hinge part 32. This allows the flat wire harness 20 to be maintained in an attachment position arranged along the reinforcement 11. When manufacturing the attachment structure 10 for the flat wire harness, first, the hinge part 30 is attached to the reinforcement 11 via the first attachment part 40, then the first arm part 31 and the second arm part 33 rotate relatively via the hinge part 32, and finally the second attachment part 50 is attached to the attachment receiving part 16. The flat wire harness 20 may be attached to the second arm part 33 at any stage before the first arm part 31 and the second arm part 33 rotate relatively via the hinge part 32.

[0047] As shown in Fig. 3, the hinge part 30 can be attached to the reinforcement 11 via the first attachment part 40 in a state where the second attachment part 50 is not attached to the attachment receiving part 16. As shown in Fig. 4, the hinge part 30 can rotate the second arm part 33 relative to the first arm part 31 via the hinge part 32 in a state where the hinge part 30 is attached to the reinforcement 11 via the first attachment part 40 and the second attachment part 50 is not attached to the attachment receiving part 16. Hereinafter, a state where the hinge part 30 is attached to the reinforcement 11 via the first attachment part 40 and the second attachment part 50 is not attached to the attachment receiving part 16, that is, a state as shown in Fig. 4, may be referred to as a provisional attachment state.

[0048] In the temporary attachment state, when the first arm portion 31 and the second arm portion 33 rotate relative to each other, a group of parts that move together with the first arm portion 31 in the same manner (here, stationary) is referred to as the first group, and a group of parts that move together with the second arm portion 33 in the same manner (here, rotating relative to the first arm portion 31) is referred to as the second group. Here, the reinforcement 11, the first attachment portion 40, and the attachment receiving portion 16 belong to the first group, and the flat wire harness 20 and the second attachment portion 50 belong to the second group.

[0049] The manner of attachment between the first attachment portion 40 and the attachment counterpart is not particularly limited and can be set appropriately. For example, the first attachment portion 40 and the attachment counterpart may be members that are locked by a locking structure such as a combination of a clip and an attachment hole or a combination of male and female snap buttons, and repeated attachment and detachment without destruction may be possible. The manner of attachment between the first attachment portion 40 and the attachment counterpart may be a method that makes it difficult to repeatedly attach and detach without destruction, such as adhesion or welding. Here, the first attachment portion 40 is a clip CL provided on the first arm portion 31. The clip CL includes a column portion PP and a locking piece EP protruding from the tip of the column portion PP. The locking piece EP is formed to be larger than the attachment hole to which the clip CL is attached. When the clip CL is inserted into the attachment hole from the tip of the column portion PP, the locking piece EP comes into contact with the peripheral portion of the attachment hole. At this time, the locking piece EP is deflected and reduced in size by receiving a force from the peripheral portion of the attachment hole, and becomes a size that can pass through the attachment hole. The locking piece EP elastically returns to its original shape after passing through the mounting hole, and is caught on the periphery of the mounting hole. The clip CL is locked in the mounting hole 15 of the base plate portion 14 of the reinforcement 11.

[0050] The manner of attachment between the second attachment portion 50 and the attachment receiving portion 16 is not particularly limited and can be set appropriately. Preferably, the second attachment portion 50 and the attachment receiving portion 16 can be attached by rotating the second arm portion 33 using the hinge portion 32. Here, the attachment manner between the second attachment portion 50 and the attachment receiving portion 16 is a manner in which they are locked by a locking structure such as a combination of a clip and an attachment hole or a combination of male and female snap buttons, and the second attachment portion 50 and the attachment receiving portion 16 can be attached by rotating the second arm portion 33 using the hinge portion 32. Here, the second attachment portion 50 is a clip CL provided on the second arm portion 33. The clip CL has a column portion PP and an engagement piece EP like the clip CL of the first attachment portion 40. The clip CL is locked to the attachment hole 16 of the base plate portion 14 in the reinforcement 11. The attachment hole 16 of the base plate portion 14 is the attachment receiving portion 16. When the second mounting portion 50 is provided on the second arm portion 33, the second arm portion 33 becomes longer, but even if the rigidity of the flat wire harness 20 is low, it can extend from the hinge portion 32 to the second mounting portion 50 without bending.

[0051] Here, the flat wire harness 20 is attached to the second arm portion 33. The second arm portion 33 may support more than half of the area along the width direction of the flat wire harness 20. The second arm portion 33 may support the entire flat wire harness 20 along the width direction.

[0052] The second arm portion 33 and the flat wire harness 20 may be attached in any manner. The second arm portion 33 and the flat wire harness 20 may be attached by a locking structure such as a combination of a clip and an attachment hole or a combination of male and female snap buttons, and may be attached in a manner that allows repeated attachment and detachment without destruction. The second arm portion 33 and the flat wire harness 20 may be attached in a manner that makes it difficult to repeatedly attach and detach without destruction, such as by adhesion or welding.

[0053] As shown in FIG. 3, a plurality of sets (three sets in FIG. 3) of second mounting portions 50 and mounting receivers 16 are provided apart from each other along the longitudinal direction of the reinforcement body 12. The portion of the flat wire harness 20 that spans the plurality of sets of second mounting portions 50 and mounting receivers 16 is a straight path. Hinge parts 30 and base plate parts 14 are provided at positions corresponding to the plurality of sets of second mounting portions 50 and mounting receivers 16. Note that instead of the plurality of hinge parts 30, one hinge part that spans the plurality of sets of second mounting portions 50 and mounting receivers 16 may be provided. Also, instead of the plurality of base plate parts 14, one base plate part that spans the plurality of sets of second mounting portions 50 and mounting receivers 16 may be provided.

[0054] 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 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.

[0055] 2, the first attachment portion 40 and the second attachment portion 50 are attached to the base plate portion 14, and the flat wire harness 20 spreads out in a planar shape along the base plate portion 14. The portions of the flat wire harness 20 between the multiple base plate portions 14 spread out in a planar shape due to the rigidity of the flat wire harness 20 itself.

[0056] <Effects> According to the mounting structure 10 for the flat wire harness configured as described above, when the first mounting portion 40 is attached to the reinforcement 11 and the second mounting portion 50 is not attached to the mounting receiving portion 16, the second mounting portion 50 is guided to the mounting receiving portion 16 and the flat wire harness 20 is placed in a mounting posture along the reinforcement 11 by rotating the hinge portion 32. As a result, even if the mounting receiving portion 16 is in a position that is difficult for the worker to see due to the flat wire harness 20 when the flat wire harness 20 is in the mounting posture, the second mounting portion 50 can be easily moved to the mounting receiving portion 16.

[0057] In addition, a plurality of sets of the second mounting portion 50 and the mounting receiving portion 16 are provided spaced apart from each other along the longitudinal direction of the reinforcement 11. This makes it possible to guide the second mounting portions 50 at a plurality of locations collectively along the longitudinal direction of the reinforcement 11.

[0058] In addition, the portion of the flat wire harness 20 extending between the plurality of sets of second mounting portions 50 and the mounting receivers 16 is a straight path, and the hinge parts 30 are provided at positions corresponding to the plurality of sets of second mounting portions 50 and the mounting receivers 16. This allows the flat wire harness 20, which rotates together with the second arm portions 33, to be firmly held by the plurality of hinge parts 30.

[0059] The reinforcement 11 includes a reinforcement body 12 having a circular outer circumferential surface in cross section, and the flat wire harness 20 is attached in a posture extending linearly from one end to the other end in the width direction of the flat wire harness 20. As a result, the flat wire harness 20 is attached in a posture not wrapped around the reinforcement body 12.

[0060] Further, the reinforcement 11 includes a base plate portion 14 attached to the outer periphery of the reinforcement body 12, the first attachment portion 40 and the second attachment portion 50 are attached to the base plate portion 14, and the flat wire harness 20 spreads out in a planar shape along the base plate portion 14. This makes it easier for the flat wire harness 20 to be kept in a planarly spread state.

[0061] Further, the second attachment portion 50 is provided on the second arm portion 33. This allows the second attachment portion 50 to be held firmly on the second arm portion 33.

[0062] [Note] <First Modification> Fig. 5 is a plan view showing a mounting structure 110 for a flat wire harness according to a first modified example. Fig. 6 is a cross-sectional view taken along line VI-VI in Fig. 5. Fig. 7 is a cross-sectional view taken along line VII-VII in Fig. 5. Fig. 8 is a plan view illustrating a state in which a flat wire harness 120 is mounted.

[0063] The bending path is a portion of the flat wire harness 120 that extends from the first set of second mounting portions 50A and the mounting receiver 16A to the second set of second mounting portions 50B and the mounting receiver 16B. The hinge part 30 is provided at a position corresponding to the first set of second mounting portions 50A and the mounting receiver 16A, and the hinge part 30 is not provided at a position corresponding to the second set of second mounting portions 50B and the mounting receiver 16B. This allows the multiple second mounting portions 50A, 50B to be guided together to the corresponding mounting receivers 16A, 16B even if a portion of the flat wire harness 120 that rotates together with the hinge part 30 includes a bending path.

[0064] As shown in Fig. 6, the base plate portion 14A to which the second mounting portion 50A is attached has the same length dimension as the base plate portion 14 of the above embodiment in order to attach the first mounting portion 40. The base plate portion 14B to which the second mounting portion 50B is attached does not need to attach the first mounting portion 40. For this reason, as shown in Fig. 7, the base plate portion 14B may be formed shorter than the base plate portion 14A. However, the base plate portion 14B may be formed to have the same length dimension as the base plate portion 14A.

[0065] As shown in FIG. 8, the second mounting portion 50C and the mounting receiver 16C of the third set are provided on the opposite side of the second mounting portion 50B and the mounting receiver 16B of the first set with respect to the second mounting portion 50A and the mounting receiver 16A of the first set. The portion of the flat wire harness 120 that extends from the second mounting portion 50A and the mounting receiver 16A of the first set to the second mounting portion 50C and the mounting receiver 16C of the third set is a straight path. The hinge part 30 is also provided at a position corresponding to the second mounting portion 50C and the mounting receiver 16C of the third set. This allows the flat wire harness 120 to be supported at multiple points when the second arm 33 rotates.

[0066] Although the second mounting portion 50 has been described as being provided on the second arm portion 33, this is not an essential configuration. For example, as shown in FIG. 8, the second mounting portions 50A, 50B, and 50C may be provided on the flat wire harness 120. This allows the second arm portion 33 to be shortened. The second arm portion 33 supports the first edge portion 26 of the flat wire harness 120, but does not support the second edge portion 27. This configuration is suitable, for example, when the flat wire harness 120 has high rigidity and the dimensions from the hinge portion 32 to the second mounting portions 50A and 50C are kept constant.

[0067] Up to now, the mounting mode between the base plate portion 14 and the reinforcement body 12 has been described as being welding, but this is not a required configuration. For example, as shown in FIG. 6, the mounting mode between the base plate portion 14 and the reinforcement body 12 may be a mode in which they are locked by a locking structure that combines a locking portion 17 and a mounting hole 13. The locking portion 17 is a clip CL. The clip CL has a column portion PP and a locking piece EP, similar to the clip CL of the first mounting portion 40. The clip CL protrudes from between the mounting holes 15, 16 of the base plate portion 14, and is inserted and locked into the mounting hole 13 of the reinforcement body 12.

[0068] <Second Modification> Fig. 9 is a cross-sectional view showing a mounting structure 210 for a flat wire harness according to a second modified example. Fig. 10 is a plan view illustrating a state in which the flat wire harness 20 is mounted.

[0069] The reinforcement 211 has a reinforcement body 12, but does not have a base plate portion 14. The first mounting portion 40 is attached to the reinforcement body 12, the mounting receiver 34 is provided on the first arm portion 31, and the second mounting portion 50 is attached to the mounting receiver 34. This makes it possible to keep the flat wire harness 20 in a flat, expanded state by the hinge part 30 without providing the base plate portion 14. Also, since it is not necessary to provide the base plate portion 14, an increase in the number of parts can be suppressed.

[0070] The configuration of the above-mentioned base plate portion 14 can be appropriately applied as the configuration of the first arm portion 31 instead of the base plate portion 14. For example, the first arm portion 31 may extend in a direction intersecting with the longitudinal direction of the reinforcement body 12. The first arm portion 31 may extend in a tangential direction of the circular reinforcement body 12.

[0071] The manner of attachment between the first attachment portion 40 and the reinforcement body 12 is not particularly limited and can be set appropriately. For example, the first attachment portion 40 and the reinforcement body 12 may be members that are locked by a locking structure such as a combination of a clip and an attachment hole or a combination of male and female snap buttons, and can be repeatedly attached and detached without destruction. The manner of attachment between the first attachment portion 40 and the reinforcement body 12 may be one that is difficult to repeatedly attach and detach without destruction, such as adhesion or welding. Here, a clip CL as the first attachment portion 40 is inserted and locked into the attachment hole 13 in the reinforcement body 12.

[0072] The configurations described in the above embodiments and modifications can be appropriately combined as long as they are not mutually contradictory. Any combination of two or more of the first to third modifications can be applied to the first embodiment. [Explanation of symbols]
