Description

  The present invention relates to a wire harness wiring structure of a slide seat that slides along a fixed rail fixed to a vehicle body.

  Conventionally, in order to realize various seat arrangements, a lot of slide seats that can slide along a fixed rail on the vehicle body side are adopted for vehicle seats such as minivans and SUVs. In recent years, a long slide has become popular due to the demand for comfort in the passenger compartment space.

  Conventionally, some vehicles that employ a slide seat include an electrical component mounted on the slide seat. In this case, the power supply to the electrical component is mainly performed by a wire harness in which the power supply device on the vehicle body side and the electrical component are connected.

  However, when the wire harness is routed for the purpose of supplying power to the electrical component, there is a concern that the appearance may deteriorate, and there is a concern that the wire harness and the peripheral member may interfere when the slide sheet slides. In particular, in the case where the long slide is realized as described above, the movement range of the wire harness is expanded as the slide amount of the slide sheet is increased, and thus the above-described problem becomes more remarkable.

  Therefore, conventionally, a wiring harness that is stretchable is arranged on the side of the movable rail that slidably supports the slide sheet, and the wiring harness is configured to expand and contract in the floor when the slide sheet slides. A structure has been proposed (see Patent Document 1 below).

  However, the number of electric wires that have to be routed, that is, the number of wires, has increased along with the multi-functionality of the slide sheet. In the wire structure as proposed in Patent Document 1 below, the wire harness has a large diameter. There is a problem that the wiring structure becomes larger. Further, when the diameter of the wire harness is increased, the elasticity of the wire harness is reduced, and there is a possibility that the slide of the slide sheet cannot be smoothly followed.

Japanese Patent Laid-Open No. 10-138802

  An object of this invention is to provide a wire harness wiring structure of a slide sheet that can save space even when the number of wirings increases and can smoothly follow the slide of the slide sheet.

  Further, as an aspect of the present invention, the flat cable is disposed on the inner side of the belt-like member in a bent portion where the flat cable and the belt-like member that are unwound from the winding portion are bent as the slide sheet slides. Can do.

  According to the present invention, since the belt-like member is disposed outside the bent portion of the flat cable having an appropriate restoring force with respect to the deformation in the thickness direction, the flat cable may be deformed in an unexpected direction by its own restoring force. There is no.

  In addition, for example, in the case where the guide portion for bending the flat cable and the belt-like member is provided outside the bent portion, and the like, the belt-like member is interposed between the flat cable and the guide portion. It does not slide directly on the guide portion in a state where its own restoring force is applied, and it is possible to prevent a decrease in durability due to wear or the like when sliding on the guide portion.

As an aspect of the present invention, a plurality of the flat cables can be overlapped in the thickness direction and covered with an exterior member to be integrated.

Always energized in the rewind direction.

  Here, the drawer belt 15 is a flexible belt-like member made of nylon or cloth, for example, and preferably uses a material having deformability in the thickness direction equivalent to that of the wire harness 4 (flat cable 40).

  As shown in FIGS. 2 and 5, the casing 10 has a pull-out port 10 g for pulling out the wire harness 4 and the pull-out belt 15 to the outside of the casing 10, and includes a partition wall 10 d and an outer wall 10 h of the casing 10. An L-shaped routing path 10i in plan view that communicates the second space forming portion 10b and the third space forming portion 10c with the outlet 10g is formed.

  In the wire harness routing structure 1, as shown in FIGS. 1, 2, and 4 to 6, the base end portion 4a of the wire harness 4 is fixed to the second space forming portion 10b. And while winding the base end side part of the wire harness 4 spirally centering on the base end part 4a, the winding part 4b is formed, and it routes from the outermost layer of this winding part 4b to the routing path 10j Then, it is pulled out of the casing 10 from the outlet 10g.

  Outside the casing 10, the wire harness 4 pulled out from the drawer opening 10 g is overlapped with a later-described drawer belt 15 in a U-turn shape by an appropriate guide member (not shown) disposed at the front end of the slide rail 3. The wire harness 4 is wound around and guided to the internal space of the slide rail 3, whereby the wire harness 4 is routed in the internal space.

  And the front-end | tip part 4c of the wire harness 4 routed in the internal space of the slide rail 3 is being fixed to the bracket 19. FIG. The bracket 19 fixes the distal end portion 4c of the wire harness 4 to the slide seat 2 side by attachment to the slide seat 2 side. The distal end portion 4c of the wire harness 4 includes two connectors 17 attached to the bracket 19, 18 is connected to various electrical components mounted on the slide sheet 2 via 18.

  Specifically, at the distal end portion 4 c of the wire harness 4, a plurality of flat cables 40, 40... Are connected to one wire harness 6 through the connector 17, and the wire harness 6 is further connected through the connector 17. Connected to the electrical component.

  Further, in the present embodiment, the drawer belt 15 is arranged in the routing path 10 i and the internal space of the slide rail 3 along the wire harness 4 from the outermost layer of the proximal end portion wound around the winding member 14 b. In addition, the leading end side is fixed to the leading end side of the wire harness 4 by the fixing band 16.

  As shown in FIGS. 2, 4, and 6, the pull-out belt 15 has an annular locked portion 15 a at the tip, and the engaged portion 15 a is formed on the bracket 19. The front end is fixed to the bracket 19 by being locked to the stop hook 19a.

  Further, in the bent portions P1 and P2 where the wire harness 4 and the drawer belt 15 are bent, such as the corner member 10h1 of the outer wall 10h and the guide member disposed at the front end portion of the slide rail 3 (FIGS. 2 and 4). , See FIG. 5), and the wire harness 4 is disposed on the inner side of the pull-out belt 15.

  In the case of this embodiment, in the state where the slide sheet 2 is disposed at the front end position, the bracket 19 is positioned in the vicinity of the front end portion of the slide rail 3 as shown in FIG. The wire harness 4 and the drawer belt 15 are routed only in the internal space near the front end of the slide rail 3.

  And most of the other part is accommodated in the casing 10 because the wire harness 4 is routed only in the vicinity of the front end portion of the slide rail 3. In the second storage space S2, the winding layer of the winding part 4b is largely separated from the base end part 4a as shown in FIG. 2 by the restoring force of the flat cable 40 itself constituting the wire harness 4, and the second space It winds and spreads along the semicircular arc shaped partition wall 10d of the forming portion 10b.

  As described above, the winding layer of the winding portion 4b spreads in the second storage space S2, so that the length of the wire harness 4 that forms the winding layer of the winding portion 4b, that is, the winding portion 4b. The amount of winding of the wound wire harness 4 can be increased, so that most of the wire harness 4 can be accommodated in the casing 10.

  Further, most of the other portion is wound around the take-up member 14b because the pull-out belt 15 is routed only in the vicinity of the front end portion of the slide rail 3. In the state shown in FIGS. The length of the drawer belt 15 unwound from the member 14b is the shortest, in other words, the length of the drawer belt 15 wound around the winding member 14b is the longest.

  On the other hand, when the slide seat 2 is slid to the rear end position (the direction in which the wire harness 4 is pulled out) from the state shown in FIG. 1, as shown in FIG. By sliding, the wire harness 4 housed inside the casing 10 is pulled out toward the internal space of the slide rail 3.

  The pull-out belt 15 is pulled against the urging force of the mainspring spring 14 a, so that it is unwound from the winding member 14 b and pulled out toward the internal space of the slide rail 3 as with the wire harness 4.

  Thus, with the wire harness 4 being pulled out toward the internal space of the slide rail 3, in the second storage space S2, the winding layer of the winding portion 4b approaches the base end portion 4a, and the base end The portion 4a is wound around the center. Here, the length of the wire harness 4 unwound from the winding part 4b becomes longer as the sliding amount of the slide sheet 2 increases, in other words, the length of the wire harness 4 wound around the winding part 4b. Becomes shorter.

  Then, since the winding member 14b rotates with the unwinding of the pull-out belt 15 pulled out together with the wire harness 4, the mainspring spring 14a is wound and squeezed, whereby the mainspring spring 14a biases the pull-out belt 15 in a rewinding direction. Will increase.

  In the state shown in FIGS. 5 and 6, most of the wire harness 4 and the pull-out belt 15 are pulled out from the casing 10, and here, the wire harness 4 unrolled from the winding portion 4b and the winding member 14b, The length of the pull-out belt 15 is the longest. In other words, the lengths of the wire harness 4 and the pull-out belt 15 wound around the winding portion 4b and the winding member 14b are the shortest.

  In the present embodiment, the length of the pull-out belt 15 is set to be equal to or longer than the sliding amount of the slide sheet 2 and the length of the wire harness 4 is set to the state in which the slide sheet 2 is slid to the rear end position, that is, the maximum. Even when it is slid, the length of the winding portion 4b remains at a predetermined amount as shown in FIG.

  Further, when the slide seat 2 is slid to the front end position (return direction) from the state shown in FIG. 5, the bracket 19 slides forward of the vehicle in conjunction with the slide seat 2, so that the wire harness 4 and the drawer belt The force pulling 15 will be reduced.

  In this case, the pull-out belt 15 is rewound onto the winding member 14b by the urging force in the rewinding direction of the mainspring spring 14a. And the wire harness 4 is pulled back together with the drawer belt 15 to be rewound, and this is rewound on the winding portion 4b.

  Here, as described above, since a predetermined amount of the winding part 4b remains in the state before the slide sheet 2 is slid in the return direction, the wire harness 4 is unwound in the winding part 4b. The flat cable 40) is promoted by its own restoring force.

  As described above, the wire harness 4 is rewound around the winding portion 4b, so that most of the wire harness 4 drawn out to the outside can be stored in the casing 10 again.

  The wire harness wiring structure 1 of this embodiment shown in FIGS. 1-6 is a wire harness which increases in diameter with the increase in the number of wiring by comprising the wire harness 4 with the flat cables 40, 40, ... Compared to, space can be saved even if the number of wires increases.

  In addition, a flexible pull-out belt 15 is provided along the wire harness 4 (flat cable 40) for fixing the front end portion 4c to the slide sheet 2 side, and the front end side is fixed to the front end side of the wire harness 4. And a spring unit 14 for rewinding the pull-out belt 15 unwound by the spring spring 14 a included therein, and the base end portion of the wire harness 4 is connected to the base end portion of the wire harness 4. When the slide sheet 2 is slid in the pulling direction of the wire harness 4 (here, the rear of the vehicle), the tip end portion 4c is fixed to the slide sheet 2 by winding it in a spiral shape around 4a. As the wire harness 4 is pulled out, the pull-out belt 15 is also unwound and pulled. It is issued.

  When the pull-out belt 15 is unwound, the spring spring 14a of the mainspring unit 14 increases the urging force in the direction in which the pull-out belt 15 is rewound. It will be rewound. The wire harness 4 is pulled back together with the drawn-out belt 15 to be rewound, and is rewound on the winding portion 4b. In this way, the wire harness 4 can smoothly follow the slide of the slide sheet 2.

  Further, the length of the drawer belt 15 is formed to be equal to or longer than the sliding amount of the slide sheet 2 and the length of the wire harness 4 is wound around the winding portion 4b in a state where the slide sheet 2 is slid to the maximum in the rear of the vehicle. When the mainspring unit 14 is rewound, the flat cable pulled back is wound by the restoring force of the flat cable 40 itself in the winding portion 4b remaining by a predetermined amount. The wire harness 4 can smoothly follow the slide of the slide seat 2.

  In addition, the winding portion 4b and the spring unit 14 are arranged in parallel in the longitudinal direction L of the slide rail 3, and the winding portion 4b is arranged on the front end side of the drawer belt 15 with respect to the spring unit 14. Further, the mainspring unit 14 and the winding portion 4b can be arranged in a compact manner to save space.

  Further, the wire harness 4 is disposed inside the pull-out belt 15 in the bent portions P1 and P2 where the wire harness 4 and the pull-out belt 15 which are unwound from the winding portion 4b are bent as the slide sheet 2 slides. Thus, the drawing belt 15 is disposed outside the bent portions P1 and P2 of the flat cable 40 having an appropriate restoring force against deformation in the thickness direction. For this reason, there is no possibility that the wire harness 4 may be deformed in an unexpected direction by the restoring force of itself (flat cable 40).

  Further, for example, in the case where a guide portion such as a corner portion 10h1 (see FIGS. 2 and 5) formed on the outer wall 10h is provided outside the bent portion P1, the wire harness 4 and the corner portion 10h1 are bent. Since the pull-out belt 15 is interposed in the wire harness 4, the wire harness 4 does not slide directly on the corner portion 10h1 in a state where its own restoring force is applied, and the durability is reduced due to wear or the like when sliding on the corner portion 10h1. Can be prevented.

  In addition, by overlapping the plurality of flat cables 40 in the thickness direction and forming the wire harness 4 that is covered and integrated with the exterior member 43, the plurality of flat cables 40, 40,... The wire harness 4 (flat cable 40) can follow the slide of the slide sheet 2 more smoothly without being interfered with.

In the present invention, the seat may be at least a slide seat, and may not be a rear seat disposed behind the front seat as in the above-described embodiment. Specifically, if the vehicle has a front seat or a three-row seat, it may be a third-row seat, or an auxiliary seat disposed between the left and right seats.
