Description

  The present invention relates to a wiring harness wiring device, and more particularly, to a wiring harness wiring device capable of following the operation when a device to which the wiring harness is connected is operated in two axial directions, a horizontal direction and a vertical direction. In particular, when the third row seat mounted on the rear part of the automobile can be slid back and forth in the horizontal direction, and the seat back is folded on the seat cushion and then flipped up toward the side of the vehicle body to be in the stowed position The wire harness wiring device for feeding power to the third row seat is preferably used.

  As proposed in Japanese Patent Application Laid-Open No. 2004-306679 (Patent Document 1) and Japanese Patent Application Laid-Open No. 2006-290351 (Patent Document 2), there are cases where seats are provided in three rows in a wagon type or van type vehicle. is there. When the third row seat is installed, the rear luggage space becomes narrower, so that the luggage space can be increased by using the third row seat as the storage posture. The seating posture of the third row seats can be adjusted by rotating the seat back backward and inserting it into the storage recess on the floor side, or rotating the seat back forward and folding it over the seat cushion. The seat is flipped up to the side of the vehicle body to be in the stowed position.

  Since this type of third row seat is usually not equipped with electrical components, a power supply wire harness is not wired to the third row seat. However, due to the obligation to wear all seats in the seat belt, it is necessary to attach a sensor for confirming the wearing of the belt, and a power feeding device for the third row seats is required.

  Further, the third row seat may be required to have a front / rear slide function in the same manner as the first row seat and the second row seat. In that case, it is necessary to make the wire harness connected to the third row seat follow the back-and-forth slide operation. That is, the wire harness needs to be reciprocated back and forth in the horizontal direction in order to follow the back-and-forth slide operation of the seat. It is necessary, and the wiring structure of the wire harness becomes very complicated.

  In Patent Documents 1 and 2 provided with a third row seat, there is no disclosure of a harness for feeding power to the third row seat. As disclosed in JP 2010-193599 A (Patent Document 3) and the like, the wire harness connected to the seat absorbs the extra length of the power supply device for the first row slide sheet disposed under the floor below the seat. The device is inserted and wired to the lower surface side of the seat that moves along the rail installed on the floor.

  However, if the wiring harness connected to the third row seat is wired under the floor of the third row seat, the fuel tank, hybrid vehicle and electric vehicle are often restricted by the battery and tire house installation positions, and the excess length absorbing device It is difficult to secure the wiring harness wiring space including In addition, when the third row seat is moved back and forth in the horizontal direction and rotated in the vertical direction to jump up to the side surface of the vehicle body to be in the stowed posture, the wiring harness wiring structure is very There is a complicated problem.

  The present invention has been made in view of the above problems, and the problem is that the wiring space of the wire harness and the device to which the wire harness such as the third row seat is connected operate in two axial directions, the horizontal direction and the vertical direction. It is an object of the present invention to provide a routing device that can follow the wire harness in the operation in the two axial directions.

In order to solve the above problems, a first invention is a wiring structure of a wire harness connected to a vehicle seat that performs a biaxial operation of a horizontal linear movement and a vertical rotational operation,
A sheath material made of PSD in which a caterpillar that can be bent only in one direction is surrounded by a boot made of an elastic rubber tube is used as a first PSD and a second PSD, and the wire harness is sheathed at intervals in the length direction. The first PSD and the second PSD are different in bending direction by 90 degrees, and an L-shaped relay cylinder member for changing the bending direction is interposed between the first PSD and the second PSD, and the relay cylinder member is used as an interlocking material. And following and moving the seat through the seat, the interlocking member is rotatably attached from the horizontal position to the vertical position along the side of the vehicle body, with the rotating shaft as a fulcrum, and
The first PSD that encloses the wire harness is curved in a horizontal direction inside the vehicle body panel and is movably disposed, and can follow the longitudinal movement of the seat; and
Provided is a wiring harness wiring device characterized in that the second PSD that sheathes the wire harness is routed to the seat side, and the second PSD is bent to follow the vertical rotation of the seat. doing.

  As described above, the wire harness connected to the vehicle seat that operates in the two-axis direction of the horizontal movement and the vertical movement that rotates 90 degrees from the horizontal direction and is displaced in the vertical direction is bent in only one direction. The two first PSDs and the second PSD are bent by 90 degrees in the bending direction, and are covered with an L-shaped bending direction conversion relay cylinder member that is bent by 90 degrees. With this configuration, when the sheet is moved back and forth in the horizontal direction, the first PSD bends and follows in the horizontal direction, and when the sheet is rotated from the horizontal direction to the vertical direction, the second PSD bends and follows in the vertical direction. Can do.

The caterpillar that can be bent only in one direction constituting the PSD is configured such that a rectangular frame-like block surrounding a wire harness through hole is sequentially continued in a wire harness insertion direction via a pin. In the first PSD and the second PSD, the pin The mounting direction of 90 degrees is different and the bending direction is 90 degrees,
The boot made of the rubber tube surrounding the caterpillar in the form of a square frame is a square cylinder with annular crests and troughs provided alternately in the length direction,
A mounting plate protruding from the seat cushion of the seat is attached to the interlocking member via the rotating shaft, and the relay cylinder member is attached to the interlocking member.

Since the caterpillar that can be bent only in one direction constituting the PSD can regulate the bending direction according to the mounting direction of the pin, the bending direction of the wire harness sheathed by the PSD can be regulated in a required one direction. And since PSD has shape retention property independently, it is not necessary to accommodate in a case, can reduce a number of parts, and can arrange | position in a narrow space. The caterpillar block may be made of metal, but is preferably made of a resin molded product.
The boot is formed of a square tube corrugated tube. The boot alone can be bent in two directions, up and down and left and right. However, since the caterpillar surrounded by the boot can be bent only in one direction, the PSD is an exterior material that can be bent only in one direction.

  As described above, the PSDs used as the first PSD and the second PSD have shape-retaining properties and can be bent only in one direction, so that there is no possibility of interference even if an external interference material is located in the other direction. Have Therefore, when placing the PSD with the wire harness sheathed inside the vehicle body panel on the side where the seat is placed, it is not necessary to protect the extra harness housing case through the wire harness, and the wire harness is sheathed with the PSD. It can be routed in a state, and the equipment becomes simple, and it can be routed with a margin in the body panel in a narrow space.

The second invention uses a corrugated tube in place of the exterior material made of the second PSD. That is,
A wiring structure of a wire harness connected to a vehicle seat that performs a biaxial operation of a horizontal linear movement and a vertical rotation operation,
The PSD and corrugated tube, which is a caterpillar that can be bent only in one direction, is surrounded by a boot made of a stretchable rubber tube, and the wire harness is sheathed at intervals in the length direction. The bending direction of the corrugated tube is changed by 90 degrees, and an L-shaped relay cylinder member for bending direction conversion is interposed between the PSD and the corrugated tube, and the relay cylinder member is attached to the sheet via an interlocking member. Following and moving back and forth, the interlocking member is rotatably attached from the horizontal position to the vertical position along the side of the vehicle body with the rotation axis as a fulcrum, and
The PSD that sheathes the wire harness is bent in a horizontal direction inside the vehicle body panel so as to be movable, and can be moved following the longitudinal movement of the seat; and
Provided is a wiring harness routing device in which the corrugated tube that sheathes the wire harness is routed to the seat side, and the corrugated tube is bent to follow the vertical rotation of the seat. doing.

  As described above, in the second invention, the wire harness routed from the relay cylinder member to the seat side is covered with a corrugated tube instead of PSD. This is because the dimension from the outlet of the relay cylinder member to the sheet is less than 200 mm and is a short dimension. Therefore, when the sheet rotates from the use position to the stored position, the bending dimension of the wire harness is short and the bending direction becomes unstable. In addition, since the bending load is small, the wires of the wire harness are not damaged. Therefore, in 2nd invention, it replaces with 2nd PSD and uses the corrugated tube whose protection function is lower than PSD as an exterior material. Thus, if the second PSD is replaced with a corrugated tube, cost reduction can be achieved.

  Specifically, the seat that operates in the biaxial direction in the first and second inventions is a third-row seat mounted on a van-type or wagon-type vehicle, and the third-row seat slides back and forth. At the same time, it is preferably used when the seat back is folded up on the seat cushion and is then flipped up to the side vehicle body to be in the accommodation posture.

  As described above, conventionally, the third-row seats are often not provided with a front / rear slide mechanism, and even if a seat belt is attached, a sensor for confirming belt wearing is not provided. The feeding harness is not wired to the row sheet. However, seat belts are required to be worn, and wiring of the wire harness is required to energize the third row seats to the seat belt wearing confirmation sensor. As described above, when the wire harness having the routing structure of the present invention is connected to the third row seat which is slid forward and backward and jumps up to the side vehicle body to be in the storage posture, the biaxial direction of the third row seat is connected. A wire harness can be made to follow operation | movement, and it can supply electric power to the sensor for belt wear confirmation of a 3rd row | line seat.

As described above, in the apparatus for routing a wire harness to a seat of the present invention, an exterior material made of PSD that surrounds a caterpillar that can be bent only in one direction with a boot is used as the exterior material that is exteriorized on the wire harness. The caterpillar has shape retention and surrounds the caterpillar with boots, so that the wire harness inserted into the PSD can be reliably protected. Therefore, when the wire harness that operates following the movement of the seat is packaged with the PSD, it is not necessary to protect the wire harness in the region where the tracking operation is performed by inserting the wire harness into the extra length absorption case, and the wire harness can be arranged in a narrow space.
Further, in the first invention, since the wire harness is packaged using two PSDs (first PSD and second PSD), the wire harness is operated in the biaxial direction to follow the operation in the biaxial direction of the seat. it can. In the second invention, since the second PSD having a short distance is used instead of the corrugated tube, the cost can be reduced.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
1st Embodiment is shown in FIG. 1 thru | or FIG.
As shown in FIG. 1, a wagon-type vehicle includes a first row seat 1 including a driver seat and a passenger seat, a second row seat 2 behind the first seat, and left and right seats 3A and 3B behind the second row seat 2. A third row sheet 3 is mounted. All of the first, second, and third row seats are slide seats that are movable in the front-rear direction, and a seat belt unit is attached. In addition, a belt wearing confirmation sensor 61 is provided that is turned on when the seat belt 60 of the seat belt unit is worn when the occupant is seated.

  The first row seat 1 and the second row seat 2 are slidable in the front-rear direction, and a reclining mechanism for tilting the seat back is provided. The left and right seats 3A, 3B of the third row sheet have the slide function as in the first row sheet and the second row sheet. In addition, as shown in FIGS. 2A and 2B, the left and right seats 3A and 3B in the third row are folded by rotating the seat back 5 so as to overlap the seat cushion 4 and then folding the seat back 5A and 3B. As shown in FIG. 5B, the storage posture is made by jumping up toward the side body (side body panel) 31, and a large luggage space S is provided between the left and right seats 3A and 3B, and the back door is opened to load the luggage. It can be loaded.

  As described above, in order to change the seat cushion 4 of the third row seat 3 from the horizontal seating posture to the vertical storage posture shown in FIG. Therefore, the wheel 35 protruding from the lower surface of the seat cushion 4 is slidably fitted to the longitudinal rail 34 provided on the floor 30 so that the wheel 35 is detachable from the rail 34 at the initial position of the seat cushion 4. In addition, it can be separated upward and can be lowered and fitted from above. Accordingly, the third row seats 3A and 3B can be slid back and forth, and can be stowed up from the seating posture mounted on the floor 30 to the storage posture.

  As shown in FIG. 4, the seat cushion 4 of the third row seat 3 is provided with a mounting plate 45 projecting toward the vehicle body panel 31 on the side, and the mounting plate 45 is attached to the interlocking member 6 as the rotating shaft 7. It is attached rotatably via. A wheel 8 protrudes from the lower surface of the interlocking member 6, and the wheel 8 is slidably fitted to a rail 36 provided on the floor 30, and the interlocking member 6 moves the seat 3 back and forth via a mounting plate 45. I can follow it.

  A relay cylinder member 10 having an L shape in plan view shown in FIG. 5 is fixed to the interlocking member 6. Specifically, the relay cylinder member 10 includes a main body 10A and a lid 10B. The wire 20 of the wire harness is inserted into the main body 10A and covered with the lid 10B in a state of being pulled out from the openings 10c and 10d at both ends in the length direction, and the bracket 10e protruding from the main body 10A is connected to the interlocking member. It is fixed to 6 with bolts. Since the relay cylinder member 10 is fixed to the interlocking member 6, the relay cylinder member 10 also moves in the front-rear direction in conjunction with the longitudinal movement of the seat 3.

  Since the wire harness wired to the third row seat 3 is a wire harness that feeds power to the belt wear detection sensor 61, the wire harness is constituted by a single electric wire 20 in the present embodiment. When the tongue member passed through the seat belt is inserted into the buckle attached to the seat cushion 4, the sensor 61 is turned on to detect that the occupant is wearing the seat belt 60, and the on signal is sent to the seat harness 21 and the electric wire 20. Via an electronic control unit (not shown). In addition, when there are a plurality of electrical components to be mounted on the third row sheet, a plurality of electric wires are wired.

  The electric wire 20 branches off from the floor harness, is routed upward in the vehicle body panel 31 from the floor side, and is fixed to the vehicle body panel 31 with a clamp 37 as shown in FIG. After bending, the relay cylinder member 10 is passed through, pulled out to the lower part of the seat cushion 4 of the seat 3, and connected to the seat harness 21 arranged in the seat cushion 4 by a connector 38.

The vehicle body panel 31 includes an outer panel 31a and an inner panel 31b, and the electric wire 20 is wired in a space 31c sandwiched between the outer panel 31a and the inner panel 31b. The electric wire 20 is externally covered with the first PSD 11 from the position fixed to the vehicle body panel 31 by the clamp 37 to the insertion end to the one end opening 10c of the relay cylinder member 10, and the electric wire 21 of the seat harness is connected to the other end opening 10d of the relay cylinder member 10. It is covered with the second PSD 12 up to the coupling end.
As shown in FIG. 8, one side 10L of the L-shaped relay cylinder member 10 is disposed through a front-rear opening 31h provided in the inner panel 31b of the vehicle body panel 31, and the inside of the opening 31h is moved when the seat 3 moves back and forth. One side of the relay cylinder member 10 can be moved back and forth.

  As shown in FIGS. 6 and 7, the first PSD 11 and the second PSD 12 are exterior materials made of PSD in which a caterpillar 15 that can be bent in only one direction is surrounded by a boot 16 made of a rubber tube that can be expanded and contracted. The first PSD 11 and the second PSD 12 are different in bending direction by 90 degrees, and the electric wire 20 is passed through the first PSD 11 and the second PSD 12 with a gap therebetween. 10 through.

The caterpillar 15 constituting the first PSD 11 and the second PSD 12 sequentially connects the square frame-shaped blocks 18 in the wire harness insertion direction via pins 19 (19A, 19B). As shown in FIG. 6D, the block 18 surrounds the wire insertion hollow 18a with the four sides of the square frame, and ribs 18b project from the outer surfaces of the two opposing sides.
At one end in the length direction, which is the connecting direction, a pair of connecting pieces 18c are provided protruding from two sides orthogonal to the side where the ribs 18b are provided, and a pin hole 18h is provided in the connecting piece 18c. The connecting piece 18c is provided so as to protrude stepwise, and a pin hole 18i is provided on the other end side in the length direction where the connecting piece 18c is not provided. As shown in FIG. The connecting piece 18c is overlapped on the outer surface of the pin 18, the pin holes 18h and 18i are connected, the pin 19 is passed, and the blocks 18 are rotatably connected to each other using the pin 19 as a rotation axis.
The other end in the length direction where the connecting piece 18c of each block 18 is not provided is provided with a closing wall 18f having a wire insertion hole 18g in the center. The blocks 18 that are sequentially connected by the pins 19 are resin molded products.
Note that the block 18 may be made of metal, and if there are a plurality of wires in the wire harness to be inserted, an opening for inserting the wire is provided without providing a closing wall.

  The boot 16 made of the rubber tube surrounding the caterpillar 15 that sequentially connects the block 18 with the pin 19 is made of a square corrugated tube, and the boot 16 has an annular crest 16a and a trough 16b in the length direction. It is alternately provided to bend and stretch. With the caterpillar 15 surrounded by the boot 16, the ribs 18 b on both sides of the caterpillar are in contact with the inner surface of the boot 16 as shown in FIG.

In the first PSD 11 shown on the left side of FIGS. 6A and 7, the connecting pieces 18 c of the blocks 18 are arranged vertically, the pins 19 </ b> A are set in the vertical direction, and the adjacent blocks 18 are sequentially connected by the pins 19 </ b> A in the vertical direction. Thus, the first PSD 11 can be bent in the horizontal direction.
On the other hand, in the second PSD 12 shown on the right side of FIG. 7, the connecting piece 18c of the block 18 is positioned on the left and right, the pin 19B is set in the horizontal direction, and the adjacent blocks 18 are sequentially connected by the horizontal pin 19B. The 2PSD 12 can be bent in the vertical direction.

  As described above, the first PSD 11 and the second PSD 12 have the pin 19 (19A, 19B) as the rotation support shaft, the first PSD 11 bends in the horizontal direction but not in the vertical direction, and the second PSD 12 bends in the vertical direction. In either case, the bending direction is restricted to one direction. The first PSD 11 and the second PSD 12 are accommodated in the extra length absorption case because the caterpillar 15 has a shape retaining property alone and is surrounded by the boot 16 so that dust or the like does not enter and inhibit the operation of the caterpillar 15. There is no need.

As described above, the electric wire 20 is passed through the first PSD 11, the L-shaped relay cylinder member 10, and the second PSD 12, and is routed from the body panel 31 side to the lower side of the seat cushion 4 of the seat 3 and wired in the seat cushion 4. A connector is connected to the seat harness 21.
When the third row seat 3 moves back and forth, the relay cylinder member 10 moves back and forth as shown in FIG. 8A via the attachment plate 45 and the interlocking member 6 for the movement of the sheet 3, and the relay cylinder member 10. The first PSD 11 bent and routed horizontally in the vehicle body panel 31 moves back and forth between the solid line position and the alternate long and short dash line position. At that time, the first PSD 11 that is curved in a horizontal J-shape between the opening 10c of the relay cylinder member 10 and the fixing point by the clamp 37 moves while changing the position of the curved vertex, as shown in FIG. Bend as shown by the horizontal arrow.

  When the seat cushion 4 shown in FIG. 4 (B) is used in the horizontal posture and the storage posture shown in FIG. 4 (C) is used, the seat back 5 is attached to the seat cushion 4 as shown in FIGS. After being tilted to the upper surface and stacked, it rolls up sideways toward the vehicle body panel 31 and rotates. As shown in FIG. 8C, the second PSD 12 that sheathes the electric wire 20 bends vertically upward from the horizontal direction to follow the operation of rotating the seat cushion 4 90 degrees upward.

  As described above, the left and right seats 3A, 3B in the third row slide in the front-rear direction, and the seat cushion 4 can be moved from the normal seating posture mounted horizontally on the floor 30 to the storage posture by flipping up. Yes. The electric wire 20 connected to the seat harness 21 in the seat cushion 4 of the third row seat 3 that performs the horizontal back-and-forth movement and the vertical rotation movement is sheathed with the first PSD 11 and routed in the vehicle body panel 31. Then, it is made to follow the forward / backward slide movement, and is covered with the second PSD 12 through the L-shaped relay cylinder member 10 for changing the direction and routed to the connecting end with the seat harness 21, and the bending direction of the second PSD 12 Is converted 90 degrees from the bending direction of the first PSD 11, the second PSD 12 can be bent in the vertical direction to follow the rotation of the seat cushion 4 in the vertical direction. Therefore, the electric wire 20 can be connected to the third row seat 3 that slides back and forth and is flipped up and stored toward the vehicle body panel 31 side, and power can be supplied to the belt 61 confirmation sensor 61 via the electric wire 21 of the seat harness. it can.

FIG. 9 shows a second embodiment.
The second embodiment differs from the first embodiment only in that a rubber corrugated tube 50 is used instead of the second PSD. The corrugated tube 50 is formed of a cylindrical tube in which annular ridges 50a and valleys 50b that are widely used are alternately provided in the length direction. Note that the square tubular boot of the first embodiment may be used as the corrugated tube 50.

The corrugated tube 50 is sheathed on the electric wire 20 passing through the opening 10 d of the relay cylinder member 10, a corrugated clamp 51 is attached at a position below the seat cushion 4, and the corrugated clamp 51 is fixed to the lower surface of the seat cushion 4. The length of the electric wire 20 from the opening 10d of the relay cylinder member 10 to the fixing position by the corrugated clamp 51 is as short as 200 mm or less.
Since other configurations are the same as those of the first embodiment, description and illustration are omitted.

Since the corrugated tube 50 can be bent in the vertical direction and the horizontal direction, it can be bent in the vertical direction in accordance with the rotation operation of the seat cushion 4. At that time, it can be bent in the left-right direction, but since the dimension is 200 mm or less, the bending in the left-right direction can be restricted simply by bending up and down following the operation of the seat cushion 4. And since the dimension of the electric wire 20 is short, the load concerning the electric wire 20 at the time of bending can be reduced.
Since other configurations are the same as those of the first embodiment, the same operations are performed.
In this 2nd Embodiment, since the corrugated tube generally used as the exterior material of the electric wire wired from the relay cylinder member 10 to a sheet | seat is used, cost reduction can be aimed at.

  The present invention is not limited to the above-described embodiment, and is used when the device to which the wire harness is connected slides in the front-rear direction and rotates in the vertical direction to operate in the biaxial direction, like the third row seat. be able to.
