  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings as modes for carrying out the present invention.

  1 and 2 show an arrangement structure 10 according to an embodiment of the present invention. The arrangement structure 10 is a structure for arranging a wire harness 14 that electrically connects the vehicle seat (see FIG. 3) 12 and the vehicle body, and the wire harness 14 is stored when the vehicle seat 12 is stored. It is possible to hide. The wire harness 14 supplies power to the vehicle seat 12, outputs a detection value of a seating sensor disposed on the vehicle seat 12, and the like.

  Specifically, the vehicle seat 12 is a seat used as a rear seat of the vehicle, a so-called rear seat. As shown in FIG. 3, the vehicle seat 12 includes a seat cushion 20 that supports a seated person's buttocks, a seat back 22 that supports the back of the seated person, and an upper end of the seat back 22. And a headrest 24 that supports the portion.

  The seat back 22 is connected to the rear end portion of the seat cushion 20 via a reclining mechanism 26 so as to be swingable. Then, by swinging the seat back 22 rearward, the vehicle seat 12 is in a posture in which the seat back 22 is erected (hereinafter referred to as “standing posture”) (one-dot chain line). The passenger can be seated on the cushion 20. On the other hand, by swinging the seat back 22 forward, the vehicle seat 12 is in a posture in which the seat back 22 is tilted forward on the seat cushion 20 (hereinafter referred to as “forward tilt posture”) (solid line). It becomes.

  Further, the seat cushion 20 is held by a body of the vehicle body on which the vehicle seat 12 is disposed so as to be swingable toward a wall surface in the vehicle interior via a link mechanism (not shown). For this reason, the vehicle seat 12 is flipped up toward the wall surface in the vehicle interior by swinging the vehicle seat 12 in the forward-facing posture. In addition, the vehicle seat 12 swings toward the side while being lifted when it is flipped up. As a result, the vehicle seat 12 is described as being stored along the wall surface in the vehicle compartment (hereinafter referred to as “stored posture”) above the deck side trim (see FIG. 7) 28 that covers the wheel house (not shown). Yes) (two-dot chain line). In other words, the vehicle seat 12 can be changed to any one of the standing posture, the forward leaning posture, and the retracted posture.

  As described above, when the wire harness 14 is connected to the vehicle seat 12 that can be changed to any one of the standing posture, the forward-facing posture, and the retracted posture for the purpose of supplying power, transmitting and receiving detection signals, and the like. In the retracted posture, the wire harness 14 may be exposed. Specifically, as shown in FIG. 4, a through hole 29 is formed in the deck side trim 28 on the vehicle body side, and the wire harness 14 connected to the vehicle body side is inserted into the through hole 29, so that the vehicle It extends toward the working sheet 12. The end of the wire harness 14 that extends toward the vehicle seat 12 is inserted into the seat cushion 20 of the vehicle seat 12 and connected to the vehicle seat 12 inside the seat cushion 20.

  As described above, the wire harness 14 connected to the vehicle body and the vehicle seat 12 has the deck side trim 28 and the vehicle seat in the posture in which the seat back 22 is tilted forward on the seat cushion 20, that is, in the forward tilt posture. 12 is located. For this reason, since the wire harness 14 is hidden by the vehicle seat 12 in the forward-turned posture, it is hardly exposed.

  However, as shown in FIG. 5, when the vehicle seat 12 is in the retracted position, the vehicle seat 12 in the forward-turned position is flipped up sideways, and the vehicle seat 12 is moved to the deck side trim 28. Move upward from the side. At this time, the wire harness 14 connected to the inside of the seat back 22 follows the seat cushion 20 as the vehicle seat 12 is flipped up, and extends toward the vehicle seat 12 lifted up. It will be in the state of taking out. For this reason, in the retracted posture, the wire harness 14 is not hidden by the vehicle seat 12 and is exposed.

  Thus, when the wire harness 14 is exposed, the designability deteriorates. Further, when the wire harness 14 is exposed, the wire harness 14 may be damaged by contact with the wire harness 14. In particular, in the retracted posture in which the wire harness 14 is exposed, an empty space is created by storing the vehicle seat 12, and a load or the like is placed in the empty space. Becomes higher. In view of the above, the vehicle seat 12 and the vehicle body are connected by the wire harness 14 using the arrangement structure 10 shown in FIGS. 1 and 2.

  Specifically, the arrangement structure 10 includes a slide plate 30 and a swing plate 32. Both the slide plate 30 and the swing plate 32 are made of a flexible material such as resin, and are generally plate-shaped. Further, as shown in FIG. 6, the deck side trim 28 has an inverted L shape in the longitudinal section along the shape of the wheel house, and the upper end of the wall surface 36 extending in the vertical direction faces the side surface of the vehicle body. In general, the upper surface 38 is curved at 90 degrees and extends in the left-right direction. A pair of upper slide rails (only one of which is shown in the figure) 50 is fixed to the inside of the deck side trim 28 so as to extend from the curved upper end of the deck side trim 28 toward the upper surface 38. ing.

  As shown in FIG. 1, the upper slide rail 50 is generally U-shaped in a longitudinal section, and is fixed to the inside of the deck side trim 28 with the openings facing each other. The slide plate 30 is slidably held at the upper end portion by the pair of upper slide rails 50.

  Further, at the center of the wall surface 36 of the deck side trim 28, as shown in FIG. 6, a pair of lower slide rails (only one of them is shown in the figure) 52 is provided so as to extend in the vertical direction. It is fixed inside the side trim 28. As shown in FIG. 1, the lower slide rail 52 is also generally U-shaped in a longitudinal section, and is fixed to the inside of the deck side trim 28 with the openings facing each other. The slide plate 30 is slidably held at the lower end by the pair of lower slide rails 52.

  As a result, the slide plate 30 slides along the wall surface 36 and the upper surface 38 of the deck side trim 28 inside the deck side trim 28. An opening 56 (see FIG. 6) slightly larger than the width of the slide plate 30 is formed between the upper slide rail 50 and the lower slide rail 52, and the slide plate 30 is exposed from the opening 56. . A hinge portion 60 is formed on the slide plate 30 exposed from the opening 56. The hinge portion 60 is formed so as to extend in a direction perpendicular to the sliding direction of the slide plate 30, and holds a swing shaft 62 disposed coaxially.

  Further, the width dimension of the swing plate 32 is approximately the same as the width dimension of the slide plate 30, and the swing plate 32 can swing to the slide plate 30 via the swing shaft 62 at one end. It is connected to. The other end of the swing plate 32 is inserted into the seat cushion 20 of the vehicle seat 12. A pair of slide rails 66 (see FIG. 1) are fixed to a cushion frame (not shown) constituting the seat cushion 20 so as to extend in a direction perpendicular to the swing shaft 62. As shown in FIG. 1, the slide rail 66 is generally U-shaped in the longitudinal section, and is fixed to the cushion frame with the openings facing each other. The swing plate 32 is slidably held at the other end by the pair of slide rails 66.

  Further, a through hole 70 is formed in the slide plate 30 above the hinge portion 60, and the wire harness 14 is inserted through the through hole 70. The wire harness 14 is connected to the vehicle seat 12 at one end and is connected to the vehicle body side at the other end. Incidentally, since the swinging plate 32 is connected to the hinge portion 60 located below the through hole 70 as described above, the wire harness 14 extending from the through hole 70 toward the vehicle seat 12 is The vehicle 12 extends toward the inside of the vehicle seat 12 while being supported on the upper surface of the swing plate 32.

  In such a structure, in the arrangement structure 10, when the vehicle seat 12 is stored, that is, when the posture of the vehicle seat 12 is changed from the forward-facing posture to the retracted posture, the swing plate 32 is mounted on the vehicle. The wire harness 14 is concealed by the swing plate 32 by swinging together with the working sheet 12. Specifically, as shown in FIG. 6, when the seat back 22 is tilted forward on the seat cushion 20, that is, when the posture of the vehicle seat 12 is set to the forward tilt posture, the arrangement structure is provided. The ten slide plates 30 slide downward, and the hinge portion 60 of the slide plate 30 is located at the lower end of the opening 56 of the deck side trim 28.

  The swing plate 32 that is swingably connected to the hinge portion 60 extends toward the inside of the seat cushion 20 of the vehicle seat 12 in the retracted position. In the retracted posture, the seat cushion 20 is generally in a posture extending in the horizontal direction, so that the swing plate 32 is also in a posture extending in the horizontal direction. For this reason, the wire harness 14 extends toward the inside of the vehicle seat 12 while being supported on the upper surface of the swing plate 32.

  When the posture of the vehicle seat 12 is changed from the forward-facing posture to the retracted posture, that is, when the vehicle seat 12 in the forward-falling posture is flipped up sideways, the vehicle seat 12 is flipped up. Accordingly, as shown in FIG. 7, the slide plate 30 slides upward. The slide plate 30 slides along the wall surface 36 and the upper surface 38 of the deck side trim 28 as described above. Since the direction along the wall surface 36 and the upper surface 38 of the deck side trim 28 is substantially the same as the direction in which the vehicle seat 12 is flipped up, the slide plate 30 is suitable as the vehicle seat 12 is flipped up. Slide to.

  As the slide plate 30 slides upward, the hinge portion 60 of the slide plate 30 moves to the upper end portion of the opening 56 of the deck side trim 28, and the swing plate 32 connected to the hinge portion 60. The one end part of also rises. Further, the other end of the swing plate 32 is slidably held by the cushion frame of the seat cushion 20, and therefore follows the seat back 22 as the vehicle seat 12 is flipped up. Thereby, the swing plate 32 swings around the swing shaft 62. That is, when the vehicle seat 12 is flipped up, the swing plate 32 follows the vehicle seat 12 and swings while rising.

  At this time, the wire harness 14 follows the vehicle seat 12, but the swing plate 32 also follows the vehicle seat 12, and therefore the wire harness 14 is always moved by the swing plate 32 from the viewpoint from the inside of the vehicle body. Covered. Thus, when the vehicle seat 12 is in the retracted position, the wire harness 14 is hidden by the swing plate 32, and the exposure of the wire harness 14 is prevented, thereby reducing the design property and the wire harness. 14 can be prevented from being damaged.

  Further, when the vehicle seat 12 is flipped up, as described above, the vehicle seat 12 is lifted and swings sideways. On the other hand, in the arrangement structure 10, when the vehicle seat 12 is flipped up, the slide plate 30 slides upward, and the swing plate 32 connected to the slide plate 30 swings. Further, the swing plate 32 is slidably held by the seat cushion 20 of the vehicle seat 12. As a result, as the vehicle seat 12 is flipped up, it is possible to cause the swing plate 32 to suitably follow and swing the vehicle seat 12 that moves upward and swings sideways. .

  Furthermore, the slide plate 30 and the swing plate 32 are formed of a flexible material, the slide plate 30 bends when sliding, and the swing plate 32 bends when swinging. As a result, the space for arranging the slide plate 30 and the swing plate 32 can be reduced, and the arrangement structure 10 can be made compact.

  Incidentally, in the above-described embodiment, the arrangement structure 10 is an example of an arrangement structure. The vehicle seat 12 is an example of a vehicle seat. The wire harness 14 is an example of a linear body. The seat cushion 20 is an example of a seat cushion. The seat back 22 is an example of a seat back. The deck side trim 28 is an example of a body. The slide plate 30 is an example of a slide body. The swing plate 32 is an example of a planar body. The swing shaft 62 is an example of a swing shaft.

  In addition, this invention is not limited to the said Example, It can implement in the various aspect which gave various change and improvement based on the knowledge of those skilled in the art. Specifically, in the above-described embodiment, when the vehicle seat 12 is flipped up, the vehicle seat 12 swings toward the side while being lifted, so that the swing plate 32 is connected to the deck side via the slide plate 30. The trim 28 is swingably connected. However, for example, when the vehicle seat 12 is held on the vehicle body so as to be swingable about a single axis, the vehicle seat 12 swings about the single axis when the vehicle seat 12 is flipped up. For this reason, in such a case, the swing plate 32 may be connected to the vehicle body side such as the deck side trim 28 so as to be directly swingable.

  In the upper embodiment, the present invention is applied to the arrangement structure 10 of the wire harness 14 that electrically connects the vehicle seat 12 and the vehicle body, but transmits a force for operating the mechanism and the like. The present invention can be applied to an arrangement structure of a linear body such as a wire.

  Further, in the above embodiment, the present invention is applied to the arrangement structure 10 of the wire harness 14 that connects the vehicle seat 12 and the vehicle body. However, other vehicles such as various vehicles such as airplanes and ships are used. It is possible to apply the present invention to an arrangement structure of a wire harness that connects a vehicle seat and a vehicle body.
