  Hereinafter, the slide wiring device according to the embodiment will be described. In the present embodiment, an example in which the slide wiring device is applied to a slide sheet device will be described. However, the present slide wiring device itself can be employed as a configuration in which a power line and a signal line are routed between the slide support object and the outside in a structure in which various slide support objects are slidably supported. .

  FIG. 1 is a schematic perspective view showing a slide sheet device 10. The slide seat device 10 is a device that supports a vehicle seat 12 so as to be movable in the front-rear direction of the vehicle, and a pair of sliders 30 that support the seat 12 are supported by a pair of rails 40 so as to be slidable. . Then, when the slider 30 moves on the rail 40, the position of the seat 12 is adjusted in the vehicle front-rear direction. The seat 12 may be provided with various sensors such as a seating sensor and various electric drive sources such as a motor for changing the posture. The slide wiring device 20 is used to electrically connect various electrical components provided on the seat 12 and the outside, and is preferably incorporated on one rail 40 side.

  2 and 3 are partially enlarged perspective views of the slide wiring device 20. The position of the slider 30 in FIG. 3 is closer to the center of the rail 40 than the position of the slider 30 in FIG. 4 is a schematic sectional view showing the relationship between the slider 30 and the rail 40 along the line IV-IV in FIG. 3, and FIG. 5 is a schematic diagram showing the relationship between the wire harness 50 and the rail 40 along the line V-V in FIG. It is sectional drawing.

  The slide wiring device 20 includes a slider 30, a rail 40, a wire harness 50, and a wire harness housing portion 60.

  The rail 40 is formed in a long shape having a linear opening 40h on one main surface, and the slider 30 is movably supported in a state of partially protruding to the outside through the linear opening 40h. Is configured to do.

  More specifically, the rail 40 is formed by bending an elongated metal plate or the like into a substantially cylindrical shape so that a long space is formed inside and a linear opening 40h is formed on one main surface. Has been. The rail 40 may be formed by molding a resin or the like in addition to bending a metal or the like.

  The linear opening 40 h is formed on the upper surface of the rail 40 along the extending direction of the rail 40. Side wall portions 41 extend from both sides of the linear opening 40 h toward the inside of the rail 40. The side wall 41 is intermittently formed with a recess for positioning and holding the slider 30 at a predetermined position of the rail 40 (see FIGS. 2 and 3).

  The long space inside the rail 40 is formed so that the movable support end 34 of the slider 30 and the wire harness 50 can be movably accommodated. Here, as a long space, a central space 42 a is formed between the pair of side wall portions 41, and a pair of side spaces 42 b is formed outside the pair of side wall portions 41. And the wire harness 50 is accommodated in the central space 42a so that a movement along the longitudinal direction is possible. The movable support end 34 of the slider 30 is accommodated in the central space 42a and the pair of side spaces 42b so as to be movable along the longitudinal direction thereof.

  Note that a cover 46 is attached to the rail 40 as required (FIGS. 2 and 3 show only a portion covering one side of the linear opening 40h, see the two-dot chain line in FIGS. 4 and 5). . The cover 46 is formed of a material that is easily elastically deformed, such as resin, and the cover main body 47 that is attached to the lateral outer surface of the linear opening 40 h in the rail 40 and the linear opening 40 h from the cover main body 47. And an elastic cover portion 48 extending upward. The base end portion of the elastic cover portion 48 is formed thinner than the tip end portion, and is easily elastically deformed at the base end portion. The elastic cover portion 48 extends above the linear opening 40h in an area where the slider 30 does not exist and covers the linear opening 40h. Thus, foreign matter such as dust is prevented from entering the rail 40 through the linear opening 40h. Further, when the slider 30 moves, the elastic cover portion 48 is pushed to the side of the linear opening 40h according to the movement, so that the movement of the slider 30 is not hindered.

  The slider 30 is a member formed of a metal plate or the like, and has a movable support end portion 34 that is movably supported in the rail 40 and a support end portion 32 that supports the sheet 12. The support end 32 is fixed to the sheet 12 by a fixing structure such as a screw fixing structure or a fitting structure. The movable support end 34 protrudes downward from the support end 32. The movable support end portion 34 has a portion 34a in which two plate-like members are overlapped, and a bent portion 34b in which the tip portions of the two plate-like members are bent outward in a substantially U shape. ing. The overlapping portion 34a is disposed in the linear opening portion 40h and the central space 42a, and the pair of bent portions 34b are passed through the distal end side spaces of the pair of side wall portions 41 in the pair of side spaces 42b. The slider 30 is supported so as to be movable along the rail 40. A roller 34r is rotatably attached to the outer surface of the tip of the pair of bent portions 34b, and the roller 34r is driven to rotate with respect to the inner surface of the side space 42b, whereby the pair of bent portions 34b are formed. It is possible to move smoothly in the pair of side spaces 42b. The slider 30 is supported so as to be movable along the rail 40 within a range that matches the movable range of the seat 12. Here, the slider 30 is movable within a range from one end portion of the rail 40 to the middle portion in the longitudinal direction.

  The wire harness 50 is formed by bundling a plurality of electric wires 51 in a linear shape. Corrugated tubes 54 are attached to the wire harness 50, and both ends of the wire harness 50 extend from both ends of the corrugated tube 54. The corrugated tube 54 will be described later in detail.

  Connectors 52 are respectively connected to both ends of the wire harness 50. The connector 52 at one end of the wire harness 50 is connected to the connector on the seat 12 side, and the connector 52 at the other end of the wire harness 50 is connected to the connector on the vehicle side.

  The wire harness 50 is set to a length dimension that is obtained by adding a length dimension required for connection to the seat 12 and the vehicle to a length dimension corresponding to the moving range of the slider 30. And while the one end side part of the wire harness 50 passes through the central space 42a in the rail 40 and is connected to the slider 30, the other end side part of the wire harness 50 is extended outward from one end part of the rail 40. Yes.

  One end of the wire harness 50 is connected to the slider 30 as follows. That is, a protector member 53 made of resin or the like is attached to the outer surface of the slider 30. The protector member 53 is formed into a cylindrical member that can be attached along the outer surface of the slider 30 by a screw or a fitting structure. One end side opening of the protector member 53 is located in the central space 42 a, and the other end side opening of the protector member 53 is located outside the rail 40. One end portion of the wire harness 50 is inserted into the protector member 53 through one end side opening of the protector member 53, and extends outward of the rail 40 from the other end side opening. Thereby, the one end part of the wire harness 50 is connected and supported by the slider 30 via the protector member 53. The one end part of the wire harness 50 is not limited to the configuration connected by the protector member 53 as described above, and may be connected to the slider 30 in a manner movable with the slider 30.

  The wire harness housing portion 60 is formed in a shape having a space capable of housing one end side portion of the wire harness extending from one end portion of the rail 40. Here, the wire harness housing part 60 is formed of a resin or the like into a case-like member that opens upward, and has a housing body part 62 and a connecting part 64.

  In the housing main body 62, the wire harness 50 is formed in a substantially rectangular case shape having a housing space capable of housing almost the entire portion extending from one end of the rail 40. Here, since the slider 30 can move to the position of one end of the rail 40, almost the entire wire harness 50 extends from one end of the rail 40. For this reason, the housing body 62 has a housing space in which almost the entire wire harness 50 can be housed. But when the slider 30 stops on the way to the one end part of the rail 40, the accommodation main-body part 62 should just have the space which can accommodate a part of wire harness 50. FIG.

  More specifically, the accommodating main body 62 is formed in a long case shape that can be accommodated in a state where the wire harness 50 is bent in a substantially U shape, in other words, folded in half. That is, an accommodation space having a width dimension that is approximately half the length dimension of the wire harness 50 and that can accommodate two wire harnesses 50 side by side is formed in the accommodation main body 62. ing. Further, a lead-out port 62 h for leading the other end portion of the wire harness 50 to the outside is formed at the bottom of the housing main body 62.

  The connecting portion 64 is formed integrally with one end portion of one side portion of the housing main body portion 62 and is configured to be connectable to one end portion of the rail 40. The internal space of the connecting portion 64 communicates with the housing main body portion 62. Further, the connecting portion 64 and one end of the rail 40 are configured to be connectable by a fitting structure, a screw-fastening structure, or the like. And communicate with each other. And in this connection state, the said accommodating main-body part 62 is attached to the one end part of the rail 40 along the longitudinal direction.

  In a state where the wire harness accommodating portion 60 is attached to the rail 40, the other end portion of the wire harness 50 extending from one end portion of the rail 40 is guided into the accommodating main body portion 62 through the inner space of the connecting portion 64. . In a state where the slider 30 is disposed at a position closest to one end of the rail 40 within the moving range (see FIG. 2), the other end portion of the wire harness 50 guided into the housing body 62 is the housing body. In the part 62, it arrange | positions along the inner surface of the side far from the rail 40, and bend | folds in a substantially U shape in the other side part of the connection part 64. FIG. Furthermore, the other end portion of the wire harness 50 is disposed along the inner side of the housing main body 62 on the side close to the rail 40 and led out to the outside through the upper outlet 62h. Further, in a state where the slider 30 is disposed at a position farthest from one end of the rail 40 within the movement range (see FIG. 3), the other end portion of the wire harness 50 guided into the housing main body 62 is: It is bent in a substantially C shape, reaches the outlet 62h, and is led out to the outside. In addition, the other end side part of the wire harness 50 may be guide | induced to the outlet 62h directly, without passing through a bending part.

  As the slider 30 moves, the state shown in FIG. 2 changes to the state shown in FIG. 3 or vice versa. That is, as the slider 30 moves, the length dimension of the wire harness 50 extending from the rail 40 changes, so that the bending mode (bending part) of the wire harness 50 in the wire harness accommodating portion 60 is changed according to the change. It is made to follow and respond | corresponds to the change of the said length dimension.

  More specifically, when the slider 30 moves toward the other end (intermediate portion) of the rail 40 from a state where the slider 30 is located from one end of the rail 40 (FIG. 2), one end of the wire harness 50 is moved by the movement of the slider 30. The side portion is pulled toward the other end portion (intermediate portion) through the central space 42 a in the rail 40. Thereby, the other end side part of the wire harness 50 accommodated in the wire harness accommodating part 60 is pulled out from the said wire harness 50, and is introduce | transduced in the center space 42a in the rail 40 from the one end side opening of the rail 40. . Thereby, by guiding the wire harness 50 along the rail 40, the slider 30 can be smoothly moved to the other end side of the rail 40 while suppressing the wire harness 50 from interfering with the peripheral members. . Conversely, when the slider 30 moves toward the one end of the rail 40 from the state where the slider 30 is located at the other end (intermediate) of the rail 40 (FIG. 3), the one end side portion of the wire harness 50 is moved by the movement of the slider 30. It is extruded toward the opening on one end side of the rail 40 through the central space 42 a in the rail 40. Thereby, the part accommodated in the central space 42 a of the rail 40 in the wire harness 50 is pushed toward the wire harness accommodating part 60. As a result, the other end portion of the wire harness 50 is pushed into the housing main body 62 through the inner space of the connecting portion 64. The portion of the wire harness 50 pushed into the housing body 62 is housed in the housing body 62 while being deformed to draw a larger substantially U shape while being regulated by the inner wall surface of the housing body 62. . Thereby, by moving the slider 30 to the one end part side of the rail 40, the other end side part of the wire harness 50 which became unnecessary can be smoothly accommodated in the accommodating main-body part 62, and the said wire harness 50 is the said wire harness 50. The slider 30 can be smoothly moved to one end side of the rail 40 while suppressing interference with the peripheral members.

  In addition, although the wire harness accommodating part 60 was demonstrated in the said example in the example formed in the case shape which upper direction opens, it is not necessarily required. The case-like side wall portion may be partially opened, or the upper portion may be closed. Moreover, the wire harness accommodating part 60 does not necessarily need to be arrange | positioned along the said rail 40 on the one side outer side of the rail 40. As shown in FIG. The wire harness housing portion may be disposed on one end extension of the rail or the like, or may be provided above or below the rail 40.

  The corrugated tube 54 attached to the wire harness 50 will be described. 6 is a plan view showing the corrugated tube 54, FIG. 7 is a schematic sectional view showing the relationship between the regulating member 80 attached to the corrugated tube 54 and the rail 40, and FIG. 8 is a perspective view showing the regulating member 80. FIG. 9 is an exploded perspective view showing the regulating member 80.

  The corrugated tube 54 is a member formed in a substantially cylindrical shape with resin or the like, and has a bellows portion 56 and a flat portion 58 that can be easily bent.

  The bellows portion 56 has a shape in which annular convex portions 56a and annular concave portions 56b are alternately formed along the longitudinal direction thereof, and the peripheral wall portion between the annular convex portions 56a and the annular concave portions 56b is elastically deformed. It can be easily bent and deformed. Each annular convex part 56a may be mutually independent, or may be continued spirally.

  The flat part 58 is formed in a shape in which the same diameter part continues along the longitudinal direction. The flat portion 58 has a diameter corresponding to the annular recess 56b of the bellows portion 56, more specifically, the inner diameter and outer diameter of the flat portion 58 are substantially the same as the inner diameter and outer diameter of the smallest diameter portion of the annular recess 56b. Is formed. Accordingly, the diameter of the wire harness 50 that can be accommodated in the corrugated tube 54 is not restricted due to the formation of the flat portion 58. That is, the outer diameter of the wire harness 50 that can be accommodated in the corrugated tube 54 is restricted by the minimum diameter portion of the annular recess 56 b of the bellows portion 56 of the corrugated tube 54. Since the inner diameter of the flat portion 58 is formed to be substantially the same as the inner diameter of the smallest diameter portion of the annular recess 56b of the bellows portion 56, the formation of the flat portion 58 itself is a new restriction on the outer diameter of the corrugated tube 54. It is not a factor.

  Most of the corrugated tube 54 is the bellows portion 56, and it can be bent relatively easily and freely in the wire harness housing portion 60 and in the portion from the wire harness housing portion 60 to the rail 40.

  In addition, a regulating member 80 is attached to the middle portion of the corrugated tube 54 in the longitudinal direction. The regulating member 80 is configured to abut against the inside of the rail 40 and regulate the wire harness 50 from going out through the linear opening 40h. Here, the regulating member 80 is attached to the flat portion 58 in an outer fitting shape. However, the regulating member 80 does not need to be attached to the flat portion 58, and the flat portion 58 is not necessarily formed on the corrugated tube 54.

  More specifically, the regulating member 80 has an outer fitting portion 82 and a contact portion 84. The outer fitting portion 82 is formed in a substantially U shape, and the inner diameter of the bent portion thereof is formed according to the outer diameter of the flat portion 58 that is a part of the corrugated tube 54. In addition, lock pieces 83 each having a retaining protrusion 83 a are projected from both ends of the outer fitting portion 82. The contact portion 84 includes an outer fitting main body portion 85 that can close between both ends of the outer fitting portion 82 and an extended contact piece 86 that protrudes outward from the outer fitting main body portion 85. An arcuate peripheral surface 85 a corresponding to the outer diameter of the flat portion 58 is formed at one intermediate portion of the main surface of the outer fitting main body portion 85. An annular peripheral surface that surrounds the flat portion 58 by the inner peripheral surface of the outer fit portion 82 and the arc-shaped peripheral surface 85a of the contact portion 84 in a state where the outer fit portion 82 and the contact portion 84 are integrally combined. Is to be formed. Each of the pair of extending contact pieces 86 is formed with a lock hole portion 86h into which the lock piece 83 can be inserted. Here, two locking hole portions 86h are formed in each of the extended contact pieces 86 with a space therebetween. When the lock piece 83 is inserted into each lock hole 86h, the retaining protrusion 83a abuts against the peripheral edge of the lock hole 86h so as to prevent it from coming off. The extended contact piece 86 is connected. Then, with the flat portion 58 of the corrugated tube 54 disposed in the outer fitting portion 82, the lock pieces 83 at both ends of the outer fitting portion 82 are respectively connected to the extended contact pieces 86 on both sides of the contact portion 84. By inserting the lock member 86h into the lock hole 86h, the restricting member 80 is attached to the flat portion 58 in an outer fitting manner. At this time, by selectively inserting the lock piece 83 into one of the two lock hole portions 86h according to the outer diameter of the flat portion 58, a gap is suppressed even with respect to the flat portions 58 having different diameters. The restriction member 80 can be attached.

  In a state where the regulating member 80 is attached to the corrugated tube 54, the pair of extending contact pieces 86 extend outward on both sides. The dimension between the front-end | tip parts of a pair of extension contact piece 86 is larger than the width | variety of the center space 42a. Therefore, in a state where the corrugated tube 54 is disposed in the central space 42a, the distal end portions of the pair of extending contact pieces 86 are in contact with the distal end portions of the side wall portions 41 (see FIG. 7).

  The inner diameter of the restricting member 80 (more specifically, the dimension between the inner surfaces of both ends of the outer fitting portion 82) is set to be substantially the same as the outer dimension of the flat portion 58, and the outer diameter (more Specifically, the dimension between the outer surfaces of both end portions of the outer fitting portion 82 is preferably set smaller than the outer diameter of the annular convex portion 56 a of the bellows portion 56 of the corrugated tube 54. Thereby, the regulating member 80 can be mounted without reducing the diameter of the corrugated tube 54 and increasing the width of the central space 42a.

  In a state where the wire harness 50 to which the corrugated tube 54 is mounted is disposed in the rail 40, most of the corrugated tube 54, in particular, a portion corresponding to the outer fitting portion 82 is disposed in the central space 42a. Yes. Further, the abutment portion 84 is disposed on the inner side of the rail 40 than the pair of side wall portions 41, and the distal end portions of the pair of extending abutting pieces 86 can slide to the distal end portions of the pair of side wall portions 41 from the inner side of the rail 40. It comes to contact. Thereby, the corrugated tube 54 and the wire harness 50 inside thereof are prevented from coming out of the rail 40 through the linear opening 40h.

  In addition, when the corrugated tube 54 is pulled into the rail 40 from the opening on one end side of the rail 40, it is preferable that the regulating member 80 is more reliably inserted into the rail 40 in the above posture. For this purpose, the mounting posture of the corrugated tube 54 with respect to the protector member 53 is set to a posture corresponding to the above posture, the restricting member 80 is attached to the corrugated tube 54 at a somewhat narrow interval, or the restricting member 80 is attached to the opening of the rail 40. It is advisable to provide a guide that invites the person to the above posture.

  According to the slide wiring device 20 configured as described above, the wire harness 50 in the wire harness housing portion 60 is pulled out while the one end side portion of the wire harness 50 moves in the rail 40 as the slider 30 moves. Alternatively, the wire harness 50 can be pushed into the wire harness accommodating portion 60 and accommodated. For this reason, it is not necessary to employ a complicated configuration for winding or unwinding the wire harness, and the configuration of the slide wiring device 20 can be simplified. Moreover, since the one end side part of the wire harness 50 is connected with the slider 30 through the movement track of the slider 30, especially the slider 30, the space which arrange | positions the wire harness 50 is provided in the whole side of the rail 40. There is no need, and the slide wiring device 20 can be miniaturized and the appearance is improved.

  In addition, the wire harness housing portion 60 has a long housing body 62 that can be housed in a state where the other end portion of the wire harness 50 extending from one end portion of the rail 40 is bent into a U shape. And since the accommodating main-body part 62 is provided in the one end part of the rail 40 along the longitudinal direction, the width | variety of the slide wiring apparatus 20 can be made small and size reduction can be achieved.

  Moreover, since the regulating member 80 is attached to the corrugated tube 54 attached to the wire harness 50, the longitudinal direction intermediate portion of the wire harness 50 comes out of the rail 40 through the linear opening 40h by the regulating member 80. It is suppressed.

  The corrugated tube 54 may be omitted, and the regulating member 80 may be directly attached to the wire harness 50.

  The flat portion 58 is formed to have a diameter corresponding to the small diameter portion of the bellows portion 56, and the regulating member 80 is attached to the flat portion 58. For this reason, the thing which can be mounted | worn with the comparatively thin diameter flat part 58 can be used as the control member 80, and the diameter increase in the mounting part of the control member 80 can be suppressed. In other words, since it is not necessary to consider the increase in diameter due to the regulating member 80, the corrugated tube 54 having a diameter as large as possible can be used as long as it can be disposed in the central space 42a. Thereby, it can respond easily also to the wire harness 50 with many wires.
