Description

Technical Field

[0001] This invention relates to a harness wiring structure for supplying power to electrical components incorporated in a slide seat from a vehicle body.

Background Art

[0002] Conventionally, automobiles are equipped with slide seats that can slide in the front-rear direction, and the slide seats incorporate electrical components such as seat belt reminders and side airbag squibs. Therefore, it is necessary to supply power to these electrical components from the vehicle body (see Patent Document 1 and Patent Document 2).

[0003] By the way, when the slide seat slides in the front-rear direction, the harness spanned between the vehicle body and the slide seat deforms and the harness route changes. And when the harness is routed by bending back from the direction toward one side in the front-rear direction to the direction toward the other side, the harness is pulled as the slide seat slides, and local bending (bending with a large curvature, that is, sharp bending with a tight degree of bending) occurs in the harness, and as a result, an excessive load may act on the harness.

Problems to be Solved by the Invention

[0005] An object of the present invention is to provide a harness wiring structure capable of preventing an excessive load from acting on the harness even when the slide seat slides in the front-rear direction.

Means for Solving the Problems

[0006] The invention of the present application is a harness wiring structure for supplying power to electrical components incorporated in a slide seat from a vehicle body, including a harness spanned between the vehicle body and the slide seat, a vehicle body side holding portion fixed to the vehicle body for holding the base end side portion of the harness, and a slide seat side holding portion fixed to the slide seat for holding the tip end side portion of the harness. The harness is wired by being bent back from a direction toward one side to a direction toward the other side in the front-rear direction in which the slide seat slides. The vehicle body side holding In the part portion is provided with a bending shape regulating portion for regulating that the bending shape of the harness becomes smaller than a predetermined bending radius. , it has a protective cover part for protecting the vehicle body side holding part, and a harness guide groove for guiding the harness wound around the bending shape regulating part is provided in the protective cover part. The protective cover part has a pair of groove plates constituting the harness guide groove, and the bending shape regulating part is arranged between the pair of groove plates It is characterized by this.

[0007] Also, the invention of the present application includes a vehicle body side holding portion constituting the above-described harness wiring structure. That is, a vehicle body side holding portion for holding the base end side portion of a harness spanned between the vehicle body and the slide seat, and a bending shape regulating portion for regulating that the bending shape of the harness wired by being bent back from a direction toward one side to a direction toward the other side in the direction in which the slide seat slides becomes smaller than a predetermined bending radius is provided. , it has a protective cover part for protecting the vehicle body side holding part, and a harness guide groove for guiding the harness wound around the bending shape regulating part is provided in the protective cover part. The protective cover part has a pair of groove plates constituting the harness guide groove, and the bending shape regulating part is arranged between the pair of groove plates It is assumed that a vehicle body side holding portion is included.

[0008] According to these inventions, even if the slide seat slides in the front-rear direction, it is possible to prevent an excessive load from acting on the harness. Specifically, according to the harness routing structure, the vehicle body side holding portion, and the slide seat side holding portion according to the invention of the present application, the harness is routed by being bent back from a direction toward one side to a direction toward the other side in the front-rear direction in which the slide seat slides. Therefore, when the harness is pulled as the slide seat slides, eventually the harness will be bent back at a portion near the vehicle body side holding portion (the root portion of the harness extending from the vehicle body side holding portion) or a portion near the slide seat side holding portion (the root portion of the harness extending from the slide seat side holding portion). Accordingly, when a bending shape restricting portion is provided at the vehicle body side holding portion, the bending shape of the harness bent back at a portion near the vehicle body side holding portion can be restricted. In this way, it is possible to prevent local bending from occurring at a portion near the vehicle body side holding portion in the harness. Further, when a bending shape restricting portion is provided at the slide seat side holding portion, the bending shape of the harness bent back at a portion near the slide seat side holding portion can be restricted. In this way, it is possible to prevent local bending from occurring at a portion near the slide seat side holding portion in the harness. As a result, even when the slide seat slides in the front-rear direction, it is possible to prevent an excessive load from acting on the harness.

[0009] Also, since the bending shape regulating part is provided on the vehicle body side holding part, and it has a protective cover part for protecting the vehicle body side holding part, and a harness guide groove for guiding the harness wound around the bending shape regulating part is provided in the protective cover part, it is possible to prevent the harness from being wound obliquely around the bending shape regulating part provided on the vehicle body side holding part or from being wound in a twisted state

[0010] Moreover, the present invention is a harness wiring structure for supplying power to electrical components incorporated in a slide seat from a vehicle body. It includes a harness bridged between the vehicle body and the slide seat, a vehicle body side holding part fixed to the vehicle body for holding the base end side portion of the harness, and a slide seat side holding part fixed to the slide seat for holding the tip end side portion of the harness. The harness is wired by bending back from a direction toward one side to a direction toward the other side in the front-rear direction in which the slide seat slides. The slide seat side holding part is provided with a bending shape regulating part for regulating the bending shape of the harness to be smaller than a predetermined bending radius, and it has a protective cover part for protecting the slide seat side holding part. A harness guide groove for guiding the harness wound around the bending shape regulating part is provided in the protective cover part. The protective cover part has a pair of groove plates constituting the harness guide groove, and the bending shape regulating part is arranged between the pair of groove plates It is characterized by this.

[0011] Furthermore, the invention of the present application shall include a slide seat side holding portion that constitutes the above-described harness routing structure. That is, a slide seat side holding portion that holds the tip side portion of the harness bridged between the vehicle body and the slide seat, and a bending shape restricting portion is provided to restrict the bending shape of the harness routed by being bent back from a direction toward one side to a direction toward the other side in the direction in which the slide seat slides to be smaller than a predetermined bending radius It has a protective cover part that protects the slide sheet side holding part, and a harness guide groove for guiding the harness that is wound around the bending shape restricting part is provided in the protective cover part. The protective cover part has a pair of groove plates that constitute the harness guide groove, and the bending shape restricting part is arranged between the pair of groove plates. shall include a slide seat side holding portion.

[0012] According to these inventions, it is possible to prevent the harness from being wound obliquely around the bending shape restricting part provided on the slide sheet side holding part or from being wound in a twisted state.

[0013] As an aspect of the present invention, the bending shape regulating portion is disposed on the inner peripheral side of the bent portion in the harness, and in a state where the slide sheet is slid to a predetermined slide stroke, the bending shape regulating portion may contact a part of the inner peripheral surface of the bent portion in the harness.

[0014] According to the present invention, since the harness is pulled as the slide sheet slides, the bent portion in the harness is deformed. Then, the harness is bent along the bending shape regulating portion. Therefore, even between when a part of the inner peripheral surface of the bent portion in the harness contacts the bending shape regulating portion and when it is bent along the bending shape regulating portion, the slide sheet can be slid. Accordingly, even if the length of the harness bridged between the vehicle body and the slide sheet is set short, a necessary slide stroke can be ensured. In other words, while ensuring a necessary slide stroke, the length of the harness bridged between the vehicle body and the slide sheet can be set short. As a result, it becomes possible to achieve weight reduction and cost reduction.

[0015] Also, as an aspect of the present invention, a harness connection portion for connecting the harness may be provided on at least one of the vehicle body side holding portion and the slide sheet side holding portion. According to the present invention, when a harness connection portion is provided in the vehicle body side holding portion, it becomes possible to connect a harness extending from the slide seat side holding portion to the harness routed in the vehicle body. Further, when a harness connection portion is provided in the slide seat side holding portion, it becomes possible to connect a harness extending from the vehicle body side holding portion to the harness routed in the slide seat. Furthermore, when harness connection portions are provided in both the vehicle body side holding portion and the slide seat side holding portion, it becomes possible to change the specification of the harness bridged between the vehicle body and the slide seat regardless of whether it is the harness routed in the vehicle body or the harness routed in the slide seat. For example, it becomes possible to apply only a flexible flat cable to the harness bridged between the vehicle body and the slide seat.

[0016] As an aspect of the present invention, a harness support portion for supporting the harness along the extending direction of the harness may be provided in at least one of the vehicle body side holding portion and the slide seat side holding portion. According to the present invention, when a harness support portion is provided in the vehicle body side holding portion, it is possible to prevent the extending direction of the portion of the harness extending from the vehicle body side holding portion from being displaced, sagging due to gravity, or being twisted at least in the vicinity of the vehicle body side holding portion (the root portion of the harness extending from the vehicle body side holding portion). Further, when a harness support portion is provided in the slide seat side holding portion, it is possible to prevent the extending direction of the portion of the harness extending from the slide seat side holding portion from being displaced, sagging due to gravity, or being twisted at least in the vicinity of the slide seat side holding portion (the root portion of the harness extending from the slide seat side holding portion).

[0017] As an aspect of the present invention, the harness may be routed by being bent back perpendicular or substantially perpendicular to the floor panel constituting the vehicle body. According to the present invention, since the harness is routed while being bent back with appropriate spacing in the vertical direction, the occupied space on the floor panel is reduced. Therefore, a separate structure can be installed on the floor panel, enabling effective utilization of the interior space of the vehicle. For example, it is also possible to install a tray or the like for storing small items.

[0018] As an aspect of the present invention, the harness may be routed while being bent back between the floor panel constituting the vehicle body and the slide seat. According to the present invention, the harness can be accommodated between the floor panel and the slide seat. Therefore, it is possible to improve the aesthetics by making the harness invisible to the person sitting on the slide seat and the surrounding people.

Mode for Carrying Out the Invention

[0021] One embodiment of this invention will be described in detail with reference to the drawings. In this application, the direction of the vehicle body 100 is shown in all the drawings. Specifically, the arrow F indicates the front side, the arrow B indicates the rear side, the arrow R indicates the right side, and the arrow L indicates the left side. And the arrow U indicates the upper side, and the arrow D indicates the lower side.

[0022] FIG. 1 is a perspective view of the harness wiring structure 1. FIG. 2 is a perspective view showing the vehicle body side holding portion 3, and FIG. 3 is a cross-sectional view taken along the line A-A in FIG. 2. FIG. 4 is a perspective view showing the slide seat side holding portion 4, and FIG. 5 is a cross-sectional view taken along the line B-B in FIG. 4. Further, FIG. 6 is a front view showing the harness wiring structure 1, and FIG. 7 is a side view showing the harness wiring structure 1. Furthermore, FIG. 8 is an explanatory view showing the state where the slide seat 200 has slid, and FIG. 9 is an explanatory view showing the deformation of the bent-back portion 2R in the harness 2. And FIG. 10 is a perspective view showing the protective cover portion 5, and FIG. 11 is an explanatory view showing the situation where the harness 2 is wound around the bending shape regulating portion 313.

[0023] As shown in FIG. 1, a pair of seat rails 102 are fixed in parallel along the front-rear direction on the floor panel 101 constituting the vehicle body 100, and the slide seat 200 is placed on these seat rails 102. Therefore, the slide seat 200 can slide in the front-rear direction along these seat rails 102.

[0024] As shown in FIG. 1, the harness wiring structure 1 according to the invention of the present application supplies power to electrical components incorporated in the slide seat 200 from the vehicle body 100. Such a harness wiring structure 1 mainly includes a harness 2, a vehicle body side holding portion 3, and a slide seat side holding portion 4. Hereinafter, the harness 2, the vehicle body side holding portion 3, and the slide seat side holding portion 4 will be described in this order, and then the protective cover portion 5 that protects the vehicle body side holding portion 3 will be described.

[0025] The harness 2 is spanned between the vehicle body 100 and the slide seat 200. As shown in FIGS. 2 to 5, the harness 2 is configured by overlapping a plurality of flexible flat cables 21. Further, a connector 22 for accommodating terminal fittings is attached to the base end side portion of the harness 2. Furthermore, a connector 23 for accommodating terminal fittings is also attached to the tip end side portion thereof. Note that the harness 2 is covered with a harness exterior member 24 having flexibility.

[0026] Also, the harness 2 is routed by being bent back from the direction toward the front side F to the direction toward the rear side B in the front-rear direction in which the slide seat 200 slides. Specifically, it extends from the vehicle body side holding portion 3 fixed to the vehicle body 100 toward the front side F, and is bent back toward the rear side B at an intermediate portion and routed to the slide seat side holding portion 4. In other words, it extends from the slide seat side holding portion 4 fixed to the slide seat 200 toward the front side F, and is bent back toward the rear side B at an intermediate portion and routed to the vehicle body side holding portion 3.

[0027] The vehicle body side holding portion 3 is fixed to the vehicle body 100 and holds the base end side portion of the harness 2. Specifically, it is fixed to the floor panel 101 that constitutes the vehicle body 100 and holds the base end side portion of the harness 2 that is spanned between the vehicle body 100 and the slide seat 200. As shown in FIGS. 2 and 3, the vehicle body side holding portion 3 is mainly composed of a connector holder 31 and a connector socket 32, and the connector 22 attached to the base end side portion of the harness 2 is connected to such a connector socket 32.

[0028] The connector holder 31 has a body portion 311 formed in a substantially prismatic shape. A rectangular opening hole 31h is formed in the body portion 311 from its front surface toward the rear side B, and a connector socket 32 is fitted inside the opening hole 31h. Such a connector socket 32 houses the terminal fittings of the harness 103 routed to the vehicle body 100. The harness 103 is configured by bundling so-called coated electric wires with a round cross-sectional shape, and is guided from the rear side B of the body portion 311 to the connector socket 32 through the through-hole 10h of the floor panel 101. Note that the specifications of the connector socket 32 are not limited.

[0029] Also, the connector holder 31 has a support plate portion 312 at the lower end side portion of the body portion 311. Through-holes 31t penetrating in the vertical direction are provided on both sides of the body portion 311 across the body portion 311 in the support plate portion 312. Therefore, the connector holder 31 is attached to the floor panel 101 by bolts 33 inserted through the through-holes 31t. Further, the connector holder 31 has a bending shape restricting portion 313 at the upper end side portion of the body portion 311. The bending shape restricting portion 313 is formed in a semi-cylindrical shape parallel to the left-right direction, and protrudes toward the front side F above the connected harness 2. Note that the radius r from the central axis C to the outer peripheral surface 31s of the bending shape restricting portion 313 is set smaller than the radius R of the bent portion 2R in the harness 2 (see FIG. 7). The distance from the central axis C to the outer peripheral surface 31s of the bending shape restricting portion 313 may not be constant and may gradually change.

[0030] The slide sheet side holding part 4 is fixed to the slide sheet 200 and holds the tip side part of the harness 2. Specifically, it is fixed to the seat cushion 201 that constitutes the slide sheet 200 and holds the tip side part of the harness 2 that is bridged between the vehicle body 100 and the slide sheet 200. As shown in FIGS. 4 and 5, the slide sheet side holding part 4 is mainly composed of a connector holder 41 and a connector socket 42, and the connector 23 attached to the tip side part of the harness 2 is connected (joined) to such a connector socket 42.

[0031] The connector holder 41 has a body part 411 formed in a substantially prismatic shape. A rectangular opening hole 41h is formed in the body part 411 from its front surface toward the rear side B, and the connector socket 42 is fitted inside this opening hole 41h. Such a connector socket 42 houses the terminal fittings of the harness 203 routed to the slide sheet 200. The harness 203 is configured by bundling so-called coated electric wires with a round cross-sectional shape, and is guided from the rear side B of the body part 411 to the connector socket 42 through the through-hole 20h of the frame that supports the seat cushion 201. Note that the specifications of the connector socket 42 are not limited.

[0032] Further, the connector holder 41 has a support plate portion 412 at the upper end side portion of the body portion 411. Through holes 41t penetrating vertically are provided on both sides of the support plate portion 412 with the body portion 411 interposed therebetween. Therefore, the connector holder 41 is attached to the frame that supports the seat cushion 201 by bolts 43 inserted through the through holes 41t. In the harness wiring structure 1 according to the present embodiment, although it does not have a bending-back shape restricting portion, a bending-back shape restricting portion 413 may be provided at the lower end side portion of the body portion 411. In this case, the bending-back shape restricting portion 413 is formed in a semi-cylindrical shape parallel to the left-right direction and will project toward the front side F below the connected harness 2. And the radius from the central axis C to the outer peripheral surface 41s of the bending-back shape restricting portion 413 is set smaller than the radius R of the bending-back portion 2R in the harness 2 (see FIG. 7). The distance from the central axis C to the outer peripheral surface 41s of the bending-back shape restricting portion 413 may not be constant and may gradually change.

[0033] Incidentally, as shown in FIGS. 6 and 7, the harness 2 is routed by being bent back substantially perpendicular to the floor panel 101 between the floor panel 101 and the slide seat 200. Bending it back substantially perpendicular to the floor panel 101 is considered to reduce the occupied space on the floor panel 101. Also, routing it offset to the right side R instead of the center in the left-right direction is to ensure a large space extending to the left side L of the harness 2. Of course, if it is routed offset to the left side L, it becomes possible to ensure a large space extending to the right side R of the harness 2.

[0034] Also, as shown in FIG. 8, as the slide sheet 200 slides, the harness path will change. Specifically, as shown in FIG. 8(a), when the slide sheet 200 is slid forward to the front side F (see arrow Sf), the portion extending from the slide sheet side holding portion 4 in the harness 2 follows the front side F, so the bent portion 2R in the harness 2 becomes a harness path displaced to the front side F. Conversely, as shown in FIG. 8(b), when the slide sheet 200 is slid backward to the rear side B (see arrow Sb), the portion extending from the slide sheet side holding portion 4 in the harness 2 follows the rear side B, so the bent portion 2R in the harness 2 becomes a harness path displaced to the rear side B.

[0035] Furthermore, as shown in FIG. 9, when the slide sheet 200 is slid backward to the rear side B beyond a predetermined slide stroke, the bent portion 2R in the harness 2 will be bent along the bending shape regulating portion 313. Specifically, as shown in FIG. 9(a), when the slide sheet 200 is slid backward to the rear side B up to a predetermined slide stroke (see arrow Sb), the bending shape regulating portion 313 abuts against the lower side portion of the inner peripheral surface of the bent portion 2R in the harness 2. Thereafter, as shown in FIG. 9(b), when the slide sheet 200 is further slid backward to the rear side B (see arrow Sb), the bent portion 2R in the harness 2 is pulled and deformed to the rear side B, so that it is bent along this bending shape regulating portion 313. Thus, the harness 2 is wound around the bending shape regulating portion 313.

[0036] Next, with reference to FIGS. 10 and 11, the protective cover portion 5 for protecting the vehicle body side holding portion 3 will be described. In the harness routing structure 1, the protective cover portion 5 is formed of a resin material such as polypropylene or polyethylene. However, it may be formed of a plate material of aluminum or steel. Furthermore, it may be integrated with the floor panel 101 or the like constituting the vehicle body 100. Alternatively, it may be integrated with an interior panel or the like attached to the floor panel 101 or the like.

[0037] The protective cover part 5 has a front plate 51 and a rear plate 52 facing each other in the front-rear direction, a right plate 53 and a left plate 54 facing each other in the left-right direction, and an upper plate 55 that faces the floor panel 101 and intersects at the upper edge of each of the plates 51 to 54. Further, the protective cover part 5 has a pair of groove plates 56 that intersect perpendicularly to the front plate 51 and the upper plate 55 on the slightly right side R rather than the central part in the left-right direction. And between the pair of groove plates 56, the bending shape restricting part 313 of the vehicle body side holding part 3 is exposed.

[0038] With such a configuration, the pair of groove plates 56 will function as a harness guide groove 5G. That is, when the slide seat 200 is slid rearward B beyond a predetermined slide stroke, it will function as a harness guide groove 5G that guides the harness 2 that tries to wrap around the bending shape restricting part 313. In order to better exhibit such a function, it is preferable to appropriately set the length from one side groove plate 56 to the other side groove plate 56 to be larger than the width dimension of the harness 2.

[0039] In addition, in the protective cover part 5, in addition to the pair of groove plates 56, it has a bottom plate 57 that connects these groove plates 56. Since each groove plate 56 gradually inclines forward F as the front plate 51 goes downward, the lower side part is ensured to be longer in the front-rear direction than the upper side part. Similarly, the bottom plate 57 is also ensured to be long in the front-rear direction. Therefore, the vicinity part of the vehicle body side holding part 3 in the harness 2 (the root part of the harness 2 extending from the vehicle body side holding part 3) is sandwiched between the pair of groove plates 56 and supported by the bottom plate 57.

[0040] With such a configuration, the pair of groove plates 56 and the bottom plate 57 will function as the harness support portion 5S. That is to say, it will function as the harness support portion 5S that supports the vicinity portion (the root portion of the harness 2 extending from the vehicle body side holding portion 3) of the vehicle body side holding portion 3 in the harness 2. In order to further exert such a function, the pair of groove plates 56 and the bottom plate 57 may be extended to the front side F beyond the front plate 51. Alternatively, at a position spaced apart from the protection cover portion 5 toward the front side F, separate members corresponding to the pair of groove plates 56 and the bottom plate 57 may be provided.

[0041] As described above, the harness routing structure 1 supplies power to the electrical components incorporated in the slide seat 200 from the vehicle body 100. The harness routing structure 1 includes a harness 2 bridged between the vehicle body 100 and the slide seat 200, a vehicle body side holding portion 3 fixed to the vehicle body 100 and holding the base end side portion of the harness 2, and a slide seat side holding portion 4 fixed to the slide seat 200 and holding the tip end side portion of the harness 2. The harness 2 is routed by being bent back from the direction toward the front side F to the direction toward the rear side B in the front-rear direction in which the slide seat 200 slides. The vehicle body side holding portion 3 is provided with a bending shape regulating portion 313 that regulates the bending shape of the harness 2 from becoming smaller than a predetermined bending radius.

[0042] According to such a harness routing structure 1, even when the slide seat 200 slides in the front-rear direction, it is possible to prevent an excessive load from acting on the harness 2. Specifically, according to the harness routing structure 1 according to the invention of the present application, the harness 2 is routed by being bent back from one direction to the other direction in the front-rear direction in which the slide sheet 200 slides. Therefore, when the harness 2 is pulled as the slide sheet 200 slides, the harness 2 will eventually be bent back at the vicinity portion (the root portion of the harness 2 extending from the vehicle body side holding portion 3) of the vehicle body side holding portion 3. Therefore, when the bending shape restricting portion 313 is provided on the vehicle body side holding portion 3, the bending shape of the harness 2 bent back at the vicinity portion of the vehicle body side holding portion 3 can be restricted. In this way, it is possible to prevent local bending from occurring at the vicinity portion of the vehicle body side holding portion 3 in the harness 2. Consequently, even when the slide sheet 200 slides in the front-rear direction, it is possible to prevent an excessive load from acting on the harness 2.

[0043] Further, in the harness routing structure 1 according to the present embodiment, the bending shape restricting portion 313 is disposed on the inner peripheral side of the bent-back portion 2R of the harness 2, and in a state where the slide sheet 200 is slid to a predetermined slide stroke, the bending shape restricting portion 313 abuts against a part of the inner peripheral surface of the bent-back portion 2R of the harness 2.

[0044] According to such a harness routing structure 1, as the harness 2 is pulled as the slide sheet 200 slides, the bent-back portion 2R of the harness 2 deforms. Then, the harness 2 is bent back along the bending shape restricting portion 313. Therefore, even between the time when a part of the inner peripheral surface of the bent-back portion 2R of the harness 2 abuts against the bending shape restricting portion 313 and the time when it is bent back along the bending shape restricting portion 313, the slide sheet 200 can be slid. Therefore, even if the length of the harness 2 spanned between the vehicle body 100 and the slide sheet 200 is set short, a necessary slide stroke can be ensured. In other words, while ensuring a necessary slide stroke, the length of the harness 2 spanned between the vehicle body 100 and the slide sheet 200 can be set short. Consequently, it becomes possible to achieve weight reduction and cost reduction.

[0045] In addition, in the harness routing structure 1 according to the present embodiment, harness connection parts (connector sockets 32 and 42) for connecting the harness 2 to both the vehicle body side holding part 3 and the slide seat side holding part 4 are provided.

[0046] According to such a harness routing structure 1, regardless of whether it is the harness 103 routed on the vehicle body 100 or the harness 203 routed on the slide seat 200, it is possible to change the specifications of the harness 2 bridged between the vehicle body 100 and the slide seat 200. For example, it is possible to apply only the flexible flat cable 21 to the harness 2 bridged between the vehicle body 100 and the slide seat 200.

[0047] In addition, in the harness routing structure 1 according to the present embodiment, a harness support part 5S for supporting the harness 2 along the extending direction of the harness 2 is provided on the vehicle body side holding part 3. According to such a harness routing structure 1, it is possible to prevent the extending direction of the portion of the harness 2 extending from the vehicle body side holding part 3 from being displaced, from sagging due to gravity, or from being twisted at least in the vicinity of the vehicle body side holding part 3 (the root part of the harness 2 extending from the vehicle body side holding part 3).

[0048] In addition, in the harness routing structure 1 according to the present embodiment, the harness 2 is routed by being bent back perpendicular or substantially perpendicular to the floor panel 101 constituting the vehicle body 100. According to such a harness routing structure 1, since the harness 2 is routed by being bent back while being appropriately spaced apart in the vertical direction, the occupied space on the floor panel 101 becomes smaller. Therefore, a separate structure can be installed on the floor panel 101, and it becomes possible to effectively utilize the interior space of the vehicle. For example, it is also possible to install a tray or the like for storing small items.

[0049] In addition, in the harness routing structure 1 according to the present embodiment, the harness 2 is routed by being bent back between the floor panel 101 constituting the vehicle body 100 and the slide seat 200. According to such a harness routing structure 1, the harness 2 can be accommodated between the floor panel 101 and the slide seat 200. Therefore, it is possible to improve the aesthetic appearance by making the harness 2 invisible to the person sitting on the slide seat 200 or the surrounding people.

[0052] For example, in the harness routing structure 1 disclosed in the present application, the harness 2 is routed by being bent back from the direction toward the front side F to the direction toward the rear side B in the front-rear direction in which the slide sheet 200 slides. However, as shown in FIG. 12, it may be routed by being bent back from the direction toward the rear side B to the direction toward the front side F in the front-rear direction in which the slide sheet 200 slides.

[0053] Even in such a harness routing structure 1, if the bending shape regulating portion 313 projects upward of the harness 2 toward the rear side B, the same effects as those of the harness routing structure 1 according to the above-described embodiment can be obtained. That is, it is possible to prevent local bending from occurring in the vicinity of the vehicle body side holding portion 3 in the harness 2. As a result, even when the slide sheet 200 slides in the front-rear direction, it is possible to prevent an excessive load from acting on the harness 2.

[0054] Further, in the harness routing structure 1 disclosed in the present application, the bending shape regulating portion 313 is provided on the vehicle body side holding portion 3. However, as shown in FIG. 13, the bending shape regulating portion 413 may be provided on the slide sheet side holding portion 4. Moreover, a protective cover portion 6 for protecting the slide sheet side holding portion 4 may be provided, and a harness guide groove for guiding the harness 2 wound around the bending shape regulating portion 413 may be provided in the protective cover portion 6.

[0055] Even in such a harness routing structure 1, if the bending return shape restricting portion 413 projects downward and toward the front side F of the harness 2, the same effects as those of the harness routing structure 1 according to the above-described embodiment can be achieved. That is, it is possible to prevent local bending from occurring in the vicinity of the slide sheet side holding portion 4 in the harness 2. As a result, even when the slide sheet 200 slides in the front-rear direction, it is possible to prevent an excessive load from acting on the harness 2. Further, it is possible to prevent the harness 2 from being wound obliquely around the bending return shape restricting portion 413 provided in the slide sheet side holding portion 4, or from being wound in a twisted state.

[0056] Furthermore, in the harness routing structure 1 disclosed in the present application, the protective cover portion 5 protects the vehicle body side holding portion 3 by covering it. Therefore, as shown in FIG. 14, not only the vehicle body side holding portion 3 but also the air duct Da may be accommodated, and a blowout hole 5h may be provided in the protective cover portion 5. That is, in addition to the function of protecting the vehicle body side holding portion 3, a function of accommodating and protecting the air duct Da and supplying the air sent through the air duct Da may be added.

[0057] According to such a harness routing structure 1, the protective cover portion 5 not only protects the vehicle body side holding portion 3, but also accommodates and protects the air duct Da and can supply the air sent through the air duct Da. Therefore, it is possible to improve the aesthetics by making the air duct Da invisible to the person sitting on the slide sheet 200 and the surrounding people. In addition, since the temperature-controlled air spreads from the feet of the person sitting on the slide sheet 200 and the surrounding people, it is possible to improve the comfort of these people. At the same time, although the blowout hole 4h generates a blowing sound of the air, since the blowout hole 4h is arranged at the feet, it is difficult to notice the blowing sound, and it is possible to improve the comfort of these people.

[0058] Finally, the harness routing structure 1 disclosed in the present application has been described assuming that the harness 2 is a flexible flat cable 21. However, a so-called ribbon wire or the like having a flat cross-sectional shape may also be used. Further, the floor panel 101 has been described as a member constituting the vehicle body 100. However, a cross member or a chassis frame that supports the floor panel 101 may also be used.

[0059] In addition, the invention of the present application includes a vehicle body side holding portion 3 that holds the proximal end side portion of the harness 2 spanned between the vehicle body 100 and the slide seat 200, and the bending shape of the harness 2 routed by bending back from one side direction to the other side direction in the direction in which the slide seat 200 slides is regulated so as not to be smaller than a predetermined bending radius. The vehicle body side holding portion 3 is provided with a bending shape regulating portion 313.

[0060] Furthermore, the invention of the present application includes a slide seat side holding portion 4 that holds the distal end side portion of the harness 2 spanned between the vehicle body 100 and the slide seat 200, and the bending shape of the harness 2 routed by bending back from one side direction to the other side direction in the direction in which the slide seat 200 slides is regulated so as not to be smaller than a predetermined bending radius. The slide seat side holding portion 4 is provided with a bending shape regulating portion 413.

[0061] Also in these, the same effects as those of the harness routing structure 1 according to the invention of the present application are obtained. That is, even when the slide seat 200 slides in the front-rear direction, it is possible to prevent an excessive load from acting on the harness 2. In addition, the same effects can be obtained according to each embodiment.
