[0009] [Description of Embodiments in this Disclosure] First, the embodiments of this disclosure will be listed and described.

[0010] The mounting structure for the flat wire harness of this disclosure is as follows:

[0011] (1) A mounting structure for a flat wire harness, wherein the flat wire harness is attached to a reinforcement provided on a vehicle, comprising: a hinge component including a first arm attached to the reinforcement via a first mounting portion; a hinge portion connected to the first arm and having a rotation axis along the longitudinal direction of the reinforcement; and a second arm connected to the hinge portion on the side opposite to the first arm; and a flat wire harness provided to move integrally with the second arm when the first arm and the second arm rotate relative to each other around the rotation axis, and The mounting structure for a flat wire harness comprises a second mounting portion provided to move integrally with the flat wire harness, and a mounting receiving portion provided to rotate relative to the second mounting portion when the first arm portion and the second arm portion rotate relative to each other around the rotation axis, wherein the second mounting portion is attached to the mounting receiving portion at a position away 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 in (1), in a state where the first mounting portion is mounted to the reinforcement and the second mounting portion is not mounted to the mounting receiving portion, rotating the hinge portion guides the second mounting portion to the mounting receiving portion and brings the flat wire harness into a mounting posture along the reinforcement. Accordingly, in a state where the flat wire harness is in the mounting posture, even when the mounting receiving portion is located at a position that is not easily visible to an operator due to the flat wire harness, the second mounting portion can be easily moved to the mounting receiving portion.

[0013] In the mounting structure for the flat wire harness according to (2) of (1), a plurality of sets of the second mounting portions and the mounting receiving portions may be provided spaced apart from each other along the longitudinal direction of the reinforcement. Accordingly, the plurality of second mounting portions can be guided collectively along the longitudinal direction of the reinforcement.

[0014] In the mounting structure for the flat wire harness according to (3) of (2), a portion of the flat wire harness spanning across the plurality of sets of the second mounting portions and the mounting receiving portions is a straight path, and the hinge components may be provided at respective positions corresponding to the plurality of sets of the second mounting portions and the mounting receiving portions. Accordingly, the flat wire harness that rotates together with the second arm portion can be firmly held by the plurality of hinge components.

[0015] In the mounting structure for the flat wire harness according to (4) of (2), a portion of the flat wire harness spanning across the first set of the second mounting portion and the mounting receiving portion and the second set of the second mounting portion and the mounting receiving portion is a bent path, the hinge component is provided at a position corresponding to the first set of the second mounting portion and the mounting receiving portion, and the 2 hinge component may not be provided at a position corresponding to the second set of the second mounting portion and the mounting receiving portion. Accordingly, even when a portion of the flat wire harness that rotates together with the hinge component includes a bent path, the plurality of second mounting portions can be guided collectively to the corresponding mounting receiving portions.

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

[0017] In the flat wire harness mounting structure according to (6) (5), the reinforcement includes a base plate portion mounted on an outer peripheral portion of the reinforcement body, the first mounting portion and the second mounting portion are mounted on the base plate portion, and the flat wire harness may spread in a planar shape along the base plate portion. Thereby, the flat wire harness is easily maintained in a state of spreading in a planar shape.

[0018] In the flat wire harness mounting structure according to (7) (5), the first mounting portion may be mounted on the reinforcement body, and the mounting receiving portion may be provided on the first arm portion. Thereby, the flat wire harness can be maintained in a state of spreading in a planar shape by the hinge component without providing a base plate portion. Further, since it is not necessary to provide a base plate portion, an increase in the number of components can be suppressed.

[0019] In the flat wire harness mounting structure according to any one of (8) (1) to (7), the second mounting portion may be provided on the second arm portion. Thereby, the second mounting portion is firmly held by the second arm portion, and the dimension from the hinge portion to the second mounting portion is easily maintained at a predetermined dimension regardless of the rigidity of the flat wire harness.

[0020] In the flat wire harness mounting structure according to any one of (9) (1) to (7), the second mounting portion may be provided on the flat wire harness. Thereby, the second arm portion can be shortened.

[0021] [Detailed Description of Embodiments of the Present Disclosure] Specific examples of the mounting structure for the flat wire harness of this disclosure will be described below with reference to the drawings. However, this disclosure is not limited to these examples and is intended to include all modifications within the meaning and scope of the claims as indicated by the claims.

[0022] [Embodiment 1] The mounting structure for the flat wire harness according to Embodiment 1 will be described below. Figure 1 is a plan view showing the mounting structure 10 for the flat wire harness according to Embodiment 1. Figure 2 is a cross-sectional view taken along line II-II in Figure 1. Figure 3 is a plan view illustrating how the flat wire harness 20 is mounted. Figure 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 attached to a reinforcement 11 in the vehicle. The vehicle is, for example, an automobile. The location of the reinforcement 11 in the vehicle is not particularly limited and can be set as appropriate. Here, the reinforcement 11 is described as being located 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 into 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 in the forward direction of the vehicle. In the space inside the instrument panel, the dash panel is located in front of the reinforcement 11. The dash panel separates the space inside the instrument panel from the engine compartment. 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), etc. 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 cylindrical shape, such as a cylindrical or rectangular tube. When the reinforcement 11 is placed inside the 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 side wall of the vehicle body, and the other end is connected to the right side wall of the vehicle body.

[0026] The base plate portion 14 is attached to the outer circumference 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 Figure 2, the base plate portion 14 extends horizontally from the reinforcement body 12 to both sides. The base plate portion 14 extends tangentially to the circular reinforcement body 12. The base plate portion 14 is provided at multiple positions spaced apart along the longitudinal direction of the reinforcement body 12. Here, both the reinforcement body 12 and the base plate portion 14 are made of metal and are integrated by welding. However, the mounting method between the base plate portion 14 and the reinforcement body 12 is not limited to welding and can be set as appropriate. Also, the base plate portion 14 may be made of resin.

[0027] A flat wire harness 20 is attached to the base plate portion 14. In the example shown in Figure 2, two mounting holes 15 and 16 for attaching the flat wire harness 20 are formed in the base plate portion 14. Mounting hole 15 is at one end of the base plate portion 14 and is located on one side of the reinforcement body 12. Mounting hole 16 is at the other end of the base plate portion 14 and is located on the other side of the reinforcement body 12.

[0028] The flat wire harness 20 is formed in a flat shape. 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 arrangement. 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 can be any 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 will be described as an electric wire 22. Each of the multiple electric wires 22 is an insulated electric wire. An insulated electric wire has a conductor core wire 23 and an insulated layer 24 that covers the conductor core wire 23.

[0030] In the flat wire harness 20, the direction in which the multiple wires 22 extend is the longitudinal direction of the flat wire harness 20. The parallel direction of the multiple wires 22 is the width direction of the flat wire harness 20. The lamination direction of the wires 22 and the base material 25 is the thickness direction of the flat wire harness 20. In the flat wire harness 20, the dimensions in the extension direction and the width direction are larger than the dimensions in the thickness direction. The width dimension of the flat wire harness 20 may be the same as or larger than the width dimension of the reinforcement body 12, for example. In the flat wire harness 20, one edge along the width direction is designated as the first edge 26, and the other edge is designated as the second edge 27.

[0031] The parallel structure of the multiple electric wires 22 is not particularly limited as long as they are arranged in a flattened manner. For example, the multiple electric wires 22 may be placed separately on the main surface of the base material 25. The multiple electric wires 22 may be held in a line, or they may be held in an overlapping arrangement. In each line, adjacent electric wires 22 may be separated from each other, as shown in Figure 3. In each line, adjacent electric wires 22 may be in contact with each other.

[0032] Multiple electric wires 22 may be arranged on the main surface of the base material 25 in a bundled state. In this case, the multiple electric wires 22 may be divided into multiple groups. Specifically, the multiple electric wires 22 are bundled separately from each other in multiple groups to form multiple bundles. The multiple bundles are arranged along the main surface. This makes it easier to keep the multiple electric wires 22 in a flattened state.

[0033] Here, the base material 25 is formed in a sheet shape. The structure for holding the multiple electric wires 22 in a flattened arrangement relative to the base material 25 is not particularly limited. For example, each of the multiple 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 solvent welding), adhesive, or other means. In this case, it is easier to keep the multiple electric wires 22 in a flattened state. Alternatively, each of the multiple electric wires 22 may be fixed to the base material 25 by sewing thread. Alternatively, the multiple electric wires 22 and the base material 25 may be bound together by a binding member wrapped around the multiple electric wires 22 and the base material 25. The binding member may be, for example, a cable tie or adhesive tape.

[0034] Here, multiple wiring units 21 are stacked to form a flat wire harness 20. In each wiring unit 21, multiple electric wires 22 are held by a base material 25. In the example shown in Figure 3, there are three layers of stacked wiring units 21, but there may be two or four or more layers. In the flat wire harness 20, the wiring units 21 may not be stacked and may consist of only one layer.

[0035] The base material 25 has a first surface and a second surface facing opposite directions. Here, when the wiring body 21 is not a laminate but exists individually, the multiple wires 22 are arranged only on the first surface of the base material 25. No wires 22 are arranged on the second surface. The multiple wires 22 may be arranged separately on the first and second surfaces 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 the side edges of the multiple base materials 25 together by welding, adhesive, or other means. Alternatively, the stacked state of the multiple wiring bodies 21 may be maintained by a binding member wrapped around the multiple wiring bodies 21.

[0037] In the flat wire harness 20, the wires 22 in the wiring body 21 are fixed to a single base material 25. When the wiring body 21 is not part of a laminate and exists individually, the portion of the wire 22 facing away from the base material 25 is exposed. When multiple wiring bodies 21 are laminated, the wires 22 of the intermediate layer wiring body 21 are covered by the base material 25 of the wiring body 21 laminated on one or the other side. Even if the 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, a cover 28 is provided on the first layer wiring body 21, which is the surface layer. The cover 28 covers the electric wires 22 from the side opposite 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 a cover 28 is not provided separately from the base material 25, the exposure of the electric wires 22 on the main surface of the flat wire harness 20 may be suppressed by the base material 25 by positioning the first layer wiring body 21 so that the electric wires 22 face the second layer wiring body 21. In the flat wire harness 20, a cover 28 may not be provided, and the electric wires 22 of the first layer wiring body 21 may be exposed on the main surface of the flat wire harness 20. The side edges of the cover 28 may be fixed to the side edges of the base material 25. Even if the electric wires 22 of the first layer wiring body 21 are in contact with the cover 28, the contact portion does not need to be fixed.

[0039] The flat wire harness 20 is supported by the reinforcement 11 in a position where the width direction of the flat wire harness 20 is aligned with the horizontal direction (in this case, the front-to-back direction). The flat wire harness 20 may also be supported in a position where the width direction of the flat wire harness 20 is aligned with a direction inclined with respect to the horizontal direction.

[0040] The flat wire harness 20 is supported in a position that extends straight in the width direction. For example, even when the flat wire harness 20 is supported at the second edge 27 and the first edge 26 is a free end and extends horizontally, it may have a first rigidity such that the first edge 26 hardly sags and maintains a position that extends straight in the width direction. A part of the flat wire harness 20 along the width direction may be bent in the thickness direction relative to other parts. The flat wire harness 20 may have a second rigidity such that when the second edge 27 is supported and the first edge 26 is a free end and extends horizontally, the first edge 26 bends so that it sags vertically downward. Each individual wiring body 21 in the flat wire harness 20 may have the second rigidity, while the flat wire harness 20 formed by laminating and integrating multiple wiring bodies 21 may have the first rigidity.

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

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

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

[0044] The first mounting portion 40 is the part that attaches the first arm portion 31 to the reinforcement 11. When the first arm portion 31 and the second arm portion 33 rotate relative to each other 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 separate from the first mounting portion 40, along a direction intersecting the longitudinal direction of the reinforcement 11. The second mounting portion 50 is provided to move integrally with the flat wire harness 20 when the first arm portion 31 and the second arm portion 33 rotate relative to each other around the rotation axis, and the mounting receiver 16 is provided to rotate relative to the second mounting portion 50.

[0046] As shown in Figure 2, with the hinge component 30 attached to the reinforcement 11 via the first mounting portion 40 and the second mounting portion 50 attached to the mounting receiver 16, it is impossible for the first arm portion 31 and the second arm portion 33 to rotate relative to each other via the hinge portion 32. This keeps the flat wire harness 20 in a mounting position aligned with the reinforcement 11. In manufacturing the mounting structure 10 for the flat wire harness, first the hinge component 30 is attached to the reinforcement 11 via the first mounting portion 40, then the first arm portion 31 and the second arm portion 33 rotate relative to each other via the hinge portion 32, and finally the second mounting portion 50 is attached to the mounting receiver 16. The flat wire harness 20 may be attached to the second arm portion 33 at any stage before the first arm portion 31 and the second arm portion 33 rotate relative to each other via the hinge portion 32.

[0047] As shown in Figure 3, the hinge component 30 can be attached to the reinforcement 11 via the first mounting portion 40 even when the second mounting portion 50 is not attached to the mounting receiver portion 16. As shown in Figure 4, the hinge component 30 can rotate the second arm portion 33 relative to the first arm portion 31 via the hinge portion 32 even when it is attached to the reinforcement 11 via the first mounting portion 40 and the second mounting portion 50 is not attached to the mounting receiver portion 16. Hereafter, the state in which the hinge component 30 is attached to the reinforcement 11 via the first mounting portion 40 and the second mounting portion 50 is not attached to the mounting receiver portion 16, that is, the state shown in Figure 4, may be referred to as the temporary mounting state.

[0048] In the temporary mounting state, when the first arm 31 and the second arm 33 rotate relative to each other, the group of parts that move together with the first arm 31 and perform the same action (in this case, remain stationary) is referred to as the first group, and the group of parts that move together with the second arm 33 and perform the same action (in this case, rotate relative to the first arm 31) is referred to as the second group. Here, the reinforcement 11, the first mounting part 40 and the mounting receiving part 16 belong to the first group, and the flat wire harness 20 and the second mounting part 50 belong to the second group.

[0049] The mounting configuration of the first mounting portion 40 to the mounting mat is not particularly limited and can be set as appropriate. For example, the first mounting portion 40 and the mounting mat may be components that are locked together by a locking structure such as a combination of a clip and a mounting hole or a combination of male and female snap buttons, allowing for repeated attachment and detachment without damage. Alternatively, the mounting configuration of the first mounting portion 40 to the mounting mat may be such that repeated attachment and detachment without damage is difficult, such as by bonding or welding. Here, the first mounting 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 larger than the mounting hole to which the clip CL is attached. When the clip CL is inserted into the mounting hole from the tip of the column portion PP, the locking piece EP comes into contact with the periphery of the mounting hole. At this time, the locking piece EP is subjected to force from the periphery of the mounting hole, causing it to bend and shrink to a size that can pass through the mounting hole. The locking piece EP elastically returns to its original position after passing through the mounting hole and catches on the periphery of the mounting hole. This clip CL is locked into the mounting hole 15 of the base plate portion 14 of the reinforcement 11.

[0050] The mounting configuration of the second mounting portion 50 and the mounting receiving portion 16 is not particularly limited and can be set as appropriate. Preferably, the second mounting portion 50 and the mounting receiving portion 16 can be mounted by the rotational movement of the second arm portion 33 using the hinge portion 32. Here, the mounting configuration of the second mounting portion 50 and the mounting receiving portion 16 is such that they are locked by a locking structure such as a combination of a clip and a mounting hole or a combination of male and female snap buttons, and the second mounting portion 50 and the mounting receiving portion 16 can be mounted by the rotational movement of the second arm portion 33 using the hinge portion 32. Here, the second mounting portion 50 is a clip CL provided on the second arm portion 33. This clip CL has a column portion PP and a locking piece EP, similar to the clip CL of the first mounting portion 40. This clip CL is locked into the mounting hole 16 of the base plate portion 14 of the reinforcement 11. The mounting hole 16 of the base plate portion 14 is the mounting 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 33. The second arm 33 may support more than half of the area of ​​the flat wire harness 20 along its width direction. The second arm 33 may support the entire flat wire harness 20 along its width direction.

[0052] The method of attachment between the second arm 33 and the flat wire harness 20 is arbitrary. The method of attachment between the second arm 33 and the flat wire harness 20 may be a locking structure such as a combination of a clip and a mounting hole or a combination of male and female snap buttons, which may allow for repeated attachment and detachment without damage. The method of attachment between the second arm 33 and the flat wire harness 20 may be one that makes repeated attachment and detachment without damage difficult, such as adhesive or welding.

[0053] As shown in Figure 3, multiple sets (three sets in Figure 3) of second mounting portions 50 and mounting receiving portions 16 are provided spaced apart from each other along the longitudinal direction of the reinforcement body 12. The portion of the flat wire harness 20 that spans multiple sets of second mounting portions 50 and mounting receiving portions 16 is a straight path. Hinge components 30 and base plate portions 14 are provided at each position corresponding to the multiple sets of second mounting portions 50 and mounting receiving portions 16. Alternatively, instead of multiple hinge components 30, a single hinge component spanning multiple sets of second mounting portions 50 and mounting receiving portions 16 may be provided. Similarly, instead of multiple base plate portions 14, a single base plate portion spanning multiple sets of second mounting portions 50 and mounting receiving portions 16 may be provided.

[0054] As shown in Figure 2, the reinforcement 11 includes a reinforcement body 12 whose outer circumferential surface of the cross-section is circular, and the mounting position of the flat wire harness 20 is such that it extends linearly from one end to the other 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 to follow the circular outer circumference of the reinforcement body 12.

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

[0056] <Effects> With the flat wire harness mounting structure 10 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 receiver portion 16, rotating the hinge portion 32 guides the second mounting portion 50 to the mounting receiver portion 16 and positions the flat wire harness 20 in a mounting position aligned with the reinforcement 11. As a result, even when the mounting receiver 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 position, the second mounting portion 50 can be easily moved to the mounting receiver portion 16.

[0057] Furthermore, multiple sets of second mounting portions 50 and mounting receiving portions 16 are provided spaced apart from each other along the longitudinal direction of the reinforcement 11. This allows multiple second mounting portions 50 to be guided together along the longitudinal direction of the reinforcement 11.

[0058] Furthermore, the portion of the flat wire harness 20 that spans multiple sets of second mounting portions 50 and mounting receiving portions 16 is a straight path, and hinge components 30 are provided at each position corresponding to the multiple sets of second mounting portions 50 and mounting receiving portions 16. This allows the flat wire harness 20, which rotates together with the second arm portion 33, to be securely held by the multiple hinge components 30.

[0059] Furthermore, the reinforcement 11 includes a reinforcement body 12 whose outer circumferential surface of the cross-section is circular, and the mounting position of the flat wire harness 20 is such that it extends linearly from one end to the other in the width direction of the flat wire harness 20. As a result, the flat wire harness 20 is mounted in a position that does not wrap around the reinforcement body 12.

[0060] Furthermore, the reinforcement 11 includes a base plate portion 14 attached to the outer circumference of the reinforcement body 12, with the first mounting portion 40 and the second mounting portion 50 attached to the base plate portion 14, and the flat wire harness 20 spreading out in a planar manner along the base plate portion 14. This makes it easier to maintain the flat wire harness 20 in a planar, spread-out state.

[0061] Furthermore, a second mounting portion 50 is provided on the second arm portion 33. This ensures that the second mounting portion 50 is securely held by the second arm portion 33.

[0062] [Note] <First variation> Figure 5 is a plan view showing the mounting structure 110 of the flat wire harness according to the first modified example. Figure 6 is a cross-sectional view along the line VI-VI in Figure 5. Figure 7 is a cross-sectional view along the line VII-VII in Figure 5. Figure 8 is a plan view illustrating how the flat wire harness 120 is mounted.

[0063] The portion of the flat wire harness 120 that spans from the first set of second mounting parts 50A and mounting receiving parts 16A to the second set of second mounting parts 50B and mounting receiving parts 16B constitutes a bending path. A hinge component 30 is provided at a position corresponding to the first set of second mounting parts 50A and mounting receiving parts 16A, while a hinge component 30 is not provided at a position corresponding to the second set of second mounting parts 50B and mounting receiving parts 16B. As a result, even if the portion of the flat wire harness 120 that rotates together with the hinge component 30 includes a bending path, multiple second mounting parts 50A and 50B can be guided together to the corresponding mounting receiving parts 16A and 16B.

[0064] As shown in Figure 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 in 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 have the first mounting portion 40 attached. For this reason, as shown in Figure 7, the base plate portion 14B may be formed to be 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 Figure 8, the third set of second mounting parts 50C and mounting parts 16C are provided on the opposite side of the second set of second mounting parts 50B and mounting parts 16B from the first set of second mounting parts 50A and mounting parts 16A. The portion of the flat wire harness 120 that spans from the first set of second mounting parts 50A and mounting parts 16A to the third set of second mounting parts 50C and mounting parts 16C is a straight path. A hinge component 30 is also provided at a position corresponding to the third set of second mounting parts 50C and mounting parts 16C. This allows the flat wire harness 120 to be supported at multiple points when the second arm 33 rotates.

[0066] Up to this point, the second mounting portion 50 has been described as being provided on the second arm portion 33, but this is not an essential configuration. For example, as shown in Figure 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 rigidity of the flat wire harness 120 is high and the dimensions from the hinge portion 32 to the second mounting portions 50A and 50C are kept constant.

[0067] Up to this point, the mounting method between the base plate portion 14 and the reinforcement body 12 has been described as being by welding, but this is not an essential configuration. For example, as shown in Figure 6, the mounting method between the base plate portion 14 and the reinforcement body 12 may be a locking structure using a combination of a locking portion 17 and a mounting hole 13. The locking portion 17 is a clip CL. This 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 and 16 of the base plate portion 14 and is inserted and locked into the mounting hole 13 of the reinforcement body 12.

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

[0069] The reinforcement 211 has a reinforcement body 12 and does not have a base plate portion 14. A first mounting portion 40 is attached to the reinforcement body 12, a mounting receiving portion 34 is provided on the first arm portion 31, and a second mounting portion 50 is attached to the mounting receiving portion 34. As a result, the flat wire harness 20 can be kept in a planar, spread-out state by the hinge component 30 without the need for a base plate portion 14. Furthermore, since a base plate portion 14 is not required, the increase in the number of parts can be suppressed.

[0070] As a replacement for the base plate portion 14, the configuration of the first arm portion 31 can be appropriately applied to the base plate portion 14. For example, the first arm portion 31 may extend in a direction intersecting the longitudinal direction of the reinforcement body 12. The first arm portion 31 may also extend in a tangential direction to the circular reinforcement body 12.

[0071] The mounting configuration between the first mounting portion 40 and the reinforcement body 12 is not particularly limited and can be set as appropriate. For example, the first mounting portion 40 and the reinforcement body 12 may be components that are locked together by a locking structure such as a combination of a clip and a mounting hole or a combination of male and female snap buttons, allowing for repeated attachment and detachment without damage. Alternatively, the mounting configuration between the first mounting portion 40 and the reinforcement body 12 may be such that repeated attachment and detachment without damage is difficult, such as by bonding or welding. In this example, the clip CL, which serves as the first mounting portion 40, is inserted into and locked into the mounting hole 13 of the reinforcement body 12.

[0072] Furthermore, the configurations described in each of the above embodiments and modifications can be combined as appropriate, as long as they do not contradict each other. Any combination of two or more of the first to third modifications can be applied to the first embodiment. [Explanation of Symbols]
