Description

  The present invention relates to a wire harness routing device for a slide sheet, and more specifically, is mounted on an automobile and suitably used for a slide sheet having a slide amount of about 200 to 300 mm.

A vehicle seat is equipped with various electrical components such as an electric reclining device and a seat heater. In order to supply power to these electrical components, a power supply wire harness is routed from the vehicle body floor to the seat. In the case of a slide sheet, it is necessary to cause the wire harness to follow the sliding motion of the sheet. For this reason, the wire harness is provided with an extra length portion. The slide size of an automobile slide sheet is usually about 200 to 300 mm at maximum.
Recently, there is a slide sheet having a slide amount of 400 to 1200 mm, which is called a long slide sheet, and when the slide amount is 200 to 300 mm, it is called a short slide sheet.

  In the harness wiring device for the short slide sheet, the wire harness has a surplus length of 200 to 300 mm and is not so long. In many cases, the extra length of the wire harness is slackened in the space between the floors of the passenger compartment made of materials. Specifically, the electric wire branched from the floor harness routed along the floor panel is pulled out from the opening provided in the passenger compartment floor material, wired with an extra length corresponding to the sliding amount of the slide seat, It is connected to the seat harness that is wired inside the slide seat. The slack extra length part of the wire harness is pulled forward or backward in accordance with the back and forth movement of the slide seat.

  As described above, the extra length of the wire harness is loosened in the space between the lower surface of the slide seat and the upper surface of the passenger compartment floor material, and the extra length portion is moved forward and backward following the longitudinal movement of the slide seat. If the structure is simply pulled, the wire harness may not interfere with peripheral devices because the wire harness is not restricted during forward and backward movement. In addition, the space between the slide seat and the passenger compartment floor material cannot be used for storage, etc., and when a passenger pushes luggage into the space, it interferes with the wire harness, hindering the movement of the wire harness and causing damage. It becomes a factor.

  Moreover, as a wire harness wiring apparatus for slide sheets, the apparatus shown to FIG. 7 (A) (B) and FIG. 8 (A) (B) is provided by Unexamined-Japanese-Patent No. 2010-193599 (patent document 1). Yes. In this apparatus, a wire harness rail 102 is laid on the floor in parallel and adjacent to the side of the seat rail 101 of the slide seat 100, and the electric wire surplus is adjacent to the side of the wire harness rail 102 and in parallel. A long housing case 110 is installed. That is, a separate wire harness rail 102 and an extra wire length accommodation case 110 are arranged in parallel on the side of the seat rail 101 of the slide seat 100. The wire harness W / H to be wired to the slide sheet 100 is inserted into the electric wire surplus length accommodation case 110, and is inserted from the electric wire surplus length accommodation case 110 to the wire harness rail 102, and the slide sheet is inserted into the wire harness rail 102. The slide sheet 100 is routed through a slider 105 that is linked to the slide sheet 100.

JP 2010-193599 A

  The apparatus of Patent Document 1 is suitable for a relatively long slide sheet having a slide sheet slide amount of about 400 to 1200 mm, and the extra length portion of the wire harness W / H is inserted into the extra cable length accommodation case 110. Therefore, the route of the wire harness can be regulated and there is no problem that the wire harness directly contacts the peripheral device. However, it is necessary to lay the wire harness rail 102 and the electric wire extra length accommodation case 110 along the seat rail 101 in the lower part of the passenger compartment flooring. Since these dedicated parts are large, there is a problem that the parts cost is increased and the installation work cost is increased. In addition, there is a problem in that existing items such as an air duct already installed in the lower part of the passenger compartment interfere with the wire harness rail 102 and the extra cable length accommodation case 110. Further, since the extra cable length accommodation case 110 is made of a shallow resin case, there is a risk of damage caused by a load placed on the floor or a step.

  The present invention has been made in view of the above problems, and in a general slide seat wire harness routing device in which the slide amount of the slide seat is about 200 to 300 mm, there is no need to install a dedicated part on the floor side, It is an object to make the installation work easy without interfering with parts.

The loop of the wire harness 5 extends along the arc portion 10c on the rear end side in the wire harness insertion portion 10b.

  As described above, the extra length of the wire harness 5 is absorbed in the housing case 10 fixed to the slide sheet 1 in accordance with the slide of the slide sheet 1. Since the slider 9 fixed to the wire harness is held at a fixed position with respect to the housing case 10 that moves together with the slide sheet 1, it can be connected to the branch line 50b of the floor harness to be connected at the fixed position. Thus, since the extra length part of the wire harness does not go out from the housing case 10 to the floor, it can be prevented from interfering with peripheral devices, and the lower space of the slide seat can be used effectively.

  A procedure for assembling the housing case 10 through which the wire harness 5 has been inserted into the slide seat 1 mounted on an automobile and connecting it to the seat harness 50 will be described.

FIG. 5A shows an assembled state in which the housing case 10 is fixed to the side surface of the seat frame 40 of the slide seat 1. In this state, the wire harness 5 pulled out from the wire harness outlet 10e of the housing case 10 is fixed to the seat frame 40 in the vicinity of the wire harness outlet 10e with a clamp 14 for locking the seat, and close to the mounting position of the clamp 14 A connector 35 is attached to the wire harness terminal. The connector 35 is fitted with a connector 61 of a seat harness 60 wired in the slide seat 1.
As shown in the reference diagram of FIG. 5C, when the wire harness 5 is wound around and fixed to the wire harness outlet 10e of the housing case 10 with the tape T before being fixed to the slide sheet 1, the wire harness outlet 10e is obtained. The length (S) of the wire harness 5 drawn out from is shortened. Therefore, it is difficult to connect the connector 61 of the seat harness 60 of the slide sheet 1 and the connector 35 of the wire harness 5.

  Therefore, in the present invention, before the housing case 10 is fixed to the seat frame 40 of the slide sheet 1, the wire harness 5 is freed without being fixed by winding the wire harness 5 at the wire harness outlet 10e of the housing case 10, and FIG. ), The wire harness 5 is pulled out with the maximum length from the wire harness outlet 10e. At that time, the wire harness 5 passing through the housing case 10 is closest to the wire harness outlet 10e because the other end of the wire harness 5 is movable in the front-rear direction along the slider fitting portion 10a. The wire harness 5 is pulled out from the wire harness outlet 10e only by moving to the intermediate position in the length direction and along the front arcuate portion 10h. Thereby, the length (S) of the wire harness 5 pulled out from the wire harness outlet 10e is made much longer than the case where the tape is wound and fixed in FIG.

As described above, in the state where the length of the wire harness 5 pulled out from the wire harness outlet 10e of the housing case 10 is increased, the wire harness 5 is connected to the connector 61 of the seat harness 60 in the slide seat 1, and the housing case 10 is slid. Bolts are fixed to the seat frame 40 of the seat 1.
After that, as shown in FIG. 5A, the wire harness 5 pulled out from the wire harness outlet 10e is returned into the housing case 10, and the clamp 14 is inserted and locked into a locking hole provided in the seat frame 40.

  When the wire harness 5 is connected to the seat harness 60 and the housing case 10 is fixed to the slide seat 1 in the above procedure, the connector can be easily connected to the seat harness 60 even if the extra length of the wire harness 5 is short. .

  The wire harness routing device for a slide sheet of the present invention is not limited to the above embodiment, and can be variously modified without departing from the gist of the present invention.
