Description

Wiring structure for wire harness for slide seat

TECHNICAL FIELD The present invention relates to a wiring structure for a wire harness for a slide seat, and in particular, enables the wiring in a narrow space by shortening the front / rear operation range of the extra length portion of the wire harness that follows the back and forth movement of the slide seat mounted on the automobile. Is.

In many cases, wire harnesses that are routed on slide seats mounted on automobiles are covered with a bendable corrugated tube to allow the extra length of the wire harness to follow when the slide seat moves back and forth. When the corrugated tube is used to externally attach the wire harness, the corrugated tube can be bent in any direction of the entire circumference, so that the bending direction cannot be regulated, and there is a possibility that the corrugated tube may come into contact with peripheral devices.

In response to the above problem, the present applicant disclosed in Japanese Patent Application Laid-Open No. 2013-49402 as an exterior material for a wire harness connected to a slide sheet, as shown in FIG. Is provided. As shown in FIG. 7 (A), the caterpillar-type exterior material 100 has four bent lines A to D extending in the length direction on a resin-made belt-like flat plate and spaced apart in the middle in the width direction. The locking protrusions 102 are provided on one side of both side edges in the width direction, and the locking holes 103 are provided on the other side. As shown in FIG. 7B, it is bent along the folding lines A to D to form a square tube shape, and the locking protrusions 102 are inserted into and locked in the locking holes 103 and held in the square tube. Yes. In addition, incision lines K are provided in the width direction connecting the bent lines A to D at intervals in the length direction to separate the three

sides

111, 112, 113 of the square tube.

In the exterior material 100 assembled as described above, the side 114 without the cutting line K facing the separated central side 112 cannot extend. Therefore, as shown in FIG. 7B, the exterior material 100 sheathed on the wire harness 200 can be bent only in one direction C1 with the side 112 being the outer peripheral side, and the side 112 is the inner peripheral side. It cannot be bent in the direction C2. Thus, since the exterior material 100 can be bent only in one direction, it is suitably used as an exterior material for a wire harness that needs to regulate the bending direction and prevent contact with peripheral devices.

As shown in FIG. 7C, when the wire harness 200 routed from the floor 160 side to the slide sheet 150 mounted on the automobile is covered with the caterpillar type exterior material 100, the upper end of the exterior material 100 is placed on the slide sheet. 150 is fixed with a clip at P1 position, the extra length portion of the wire harness is curved in a U shape, and the lower end is fixed at the position P2 on the floor 160. The sheathed wire harness 200 moves to a position indicated by a solid line and a position indicated by an alternate long and short dash line in the drawing.
In many cases, the extra length portion of the wire harness that is detoured in a U shape by the exterior material 100 is accommodated in the extra length absorption case and installed below the slide sheet. As described above, when the longitudinal movement dimension of the slide sheet becomes longer, the extra length absorption case becomes longer and longer in the front-rear direction.

JP 2013-49402 A

As described above, the wire harness 200 for the slide sheet arranged between the slide sheet 150 and the floor 160 follows the exterior material 100 when the slide sheet 150 moves back and forth as indicated by the arrow FR in the figure. The wire harness thus moved moves in the front-rear direction indicated by the arrow fr. That is, when the longitudinal movement distance of the slide seat 150 is increased, the longitudinal movement distance of the wire harness 200 is also increased, and a long space in the front-rear direction is required as a wiring space for the wire harness. Furthermore, when the extra length absorbing case is used, a large installation space is required.

On the other hand, recently, due to the improvement in rigidity and weight reduction of the body under the seat, a cross member passes in the width direction in the center in the vehicle length direction below each seat, and a stepped protrusion in the vehicle length direction is formed at both ends of the cross member. In some cases, an H-type structure with a portion is provided. In the H-shaped structure, left and right seat rails are installed on the upper surfaces of the left and right stepped overhangs, and the space between the left and right seat rails is blocked by the cross member passing through the lower center of the seat. Is the wiring harness wiring space. Therefore, the space for the wire harness that needs to follow the back and forth movement of the slide seat is particularly narrow in the front-rear direction, and the wire harness is routed through two protectors: the protector attached to the seat and the protector case installed on the floor. I have to do it. In this way, when the wire harness is routed using two protectors, there is a problem that the cost is increased, and the routing operation cannot be easily performed, and the number of operations is increased.

The present invention has been made in view of the above problems, and even if the lower part of each seat has an H-type structure or the like and the wiring space for the wire harness below the seat becomes narrower, two protectors can be used and An object of the present invention is to enable the wire harness to follow the front and rear movement of the slide seat without causing damage to the wire harness.

In order to solve the above-mentioned problems, the present invention provides a rectangular frame block in which a wire harness having an extra length portion is routed between a slide seat mounted on an automobile and a vehicle body, and a wire harness insertion space is provided therein. The wire harness is sheathed with a caterpillar-shaped exterior material that is sequentially connected via a hinge part and can be bent only in one direction,
A spindle member protruding from the side surface on the sheet attachment side at one end in the length direction of the exterior material is attached to the slide sheet so as to be rotatable in the vertical direction via a rotation clamp, and the orientation of the exterior material on the sheet attachment side is horizontal. And the other side of the floor mounting side is fixed to the vehicle body via a U-shaped wiring portion that is curved at one end in the front-rear direction.
Following the back-and-forth movement of the slide sheet, the bending position of the U-shaped wiring part of the exterior material is moved forward and backward, and the sheet mounting side supported rotatably is rotated between a horizontal direction and a vertical direction. Thus, the present invention provides a wiring structure for a slide seat wire harness, wherein the wire harness is configured to follow and move.

The wire harness sheathed with the caterpillar-type exterior material is not housed in the extra length absorption case, and is curved downward at one end in the front-rear direction from the upper horizontal placement portion to form a lower horizontal placement portion, the lower horizontal placement portion The floor mounting side of the tip of the is fixed with a clamp.
It is also possible to continuously provide a straight guide portion made of an upward or lateral cross-sectional U-shaped frame at the tip of the lower horizontal arrangement portion, and to fix a clamp to the continuous portion so as to be fixed to the floor. The wire guide is inserted through the straight guide portion without being fixed, and the wire harness is pulled out from the straight guide portion when the wire harness is fixed to the automobile so that the work harness can be secured.

In the above structure, the U-shaped wiring portion of the caterpillar-type exterior material follows the front-rear movement of the slide sheet while moving the position of the curved portion back and forth, and the above-described seating side of the exterior material on the seat mounting side. The supporting shaft member supported by the rotation clamp rotates, and the sheet-side tip of the exterior material moves upward and downward to move upward and downward in the direction in which the curvature of the curved portion of the caterpillar-type exterior material increases. The vertical tracking movement dimension can be reduced by adding the vertical tracking movement to the longitudinal tracking movement. As a result, it is possible to reduce the longitudinal movement dimension of the wire harness for following the longitudinal movement of the slide sheet, and it is possible to cope with a decrease in the forward / backward movement space for the wire harness at the lower part of the slide sheet.

The caterpillar-type exterior material is a hard resin molded product, and the support shaft material that projects from one side surface orthogonal to the axial direction of the wire harness on the sheet attachment side of the exterior material comprises a corrugated projection, The rotary clamp is a corrugated clamp, and a wire harness that is pulled out from one end of the exterior material attached to the slide sheet with the corrugated clamp is routed to the seat side through the tube and connected to the seat harness that is routed inside the seat. preferable.

As described above, since the caterpillar type exterior material has high rigidity and high strength, the protection function of the wire harness from the external interference material is high. Therefore, it is not necessary to accommodate the wire harness to be sheathed with the exterior material in the protector made of the extra length absorbing case, and it is possible to cope with the case where the space for the wire harness below the slide seat is narrow. In addition, it is not necessary to protect the floor below the slide seat with the above-mentioned H shape and protect it with the two protectors required when the space for the wire harness is reduced, and cost reduction and weight reduction can be achieved.

Specifically, the tube through which the wire harness pulled out from the caterpillar type exterior material passes is made of a flexible resin tube, and the wire harness that passes through the resin tube is routed to the seat side,
Alternatively, a corrugated tube is used as a supporting shaft material protruding from the exterior material, and the corrugated clamp is attached to the corrugated tube, and the wire harness drawn from one end of the exterior material is routed to the seat side through the corrugated tube is doing.

As described above, a wire harness having a surplus length part that follows the back and forth movement of the slide sheet is covered with a caterpillar type exterior material, bent into a U shape, and pulled out from the front end of the exterior material to the sheet. Since the wire harness can be bent through the tube, the minimum bending radius of the wire harness can be maintained by the exterior material. In this way, the exterior material of the wire harness can be bent at the minimum bending radius, and the wire harness is inserted and protected through the square frame block, so that the wire passing through the exterior material is expensive and resistant to bending. It is not necessary to use an electric wire, an inexpensive general electric wire can be used, and the cost can be reduced in that respect.

The square frame block of the caterpillar type exterior material surrounds the wire harness insertion space with the upper and lower frames and the left and right side frames, and the opening on the front and rear surfaces is the wire harness insertion port,
Provided with thin-walled hinges connecting the adjacent rectangular frame blocks at the upper or lower part of the front and rear end faces of the left and right side frames,
From the state in which the square frame blocks are connected in series, the hinge portion is deformed, the adjacent square frame blocks are bent at a required bending rate, and the entire exterior material in which the square frame blocks are connected by the hinge portion Is preferably configured to bend in one direction.

Further, the caterpillar type exterior material has the upper frame as an openable / closable lid, and the wire harness electric wire group is inserted through the upper surface opening through the lid, and then the lid is closed. A square cylinder is formed by lock coupling with one of the left and right side frames, and surrounds a wire group of a wire harness to be inserted.

The hinge portion is provided at a position where the lower portions of the front and rear end faces of the left and right side frames are connected between the adjacent square frame blocks,
In addition, a bending angle restricting protrusion that protrudes toward the adjacent rectangular frame block is provided at a lower portion of the hinge portion, and at least one of the bending angle restricting protrusions has a tapered surface that is inclined from the protruding end of the upper surface toward the lower frame. A triangle with
When the hinge portion is deformed and the square frame block is connected in a bent shape, the required bending radius is set at a position where the tapered surface of the bending angle restricting projection comes into contact.

The caterpillar-type exterior material configured as described above is a caterpillar-type exterior material in which the rectangular frame blocks sequentially connected by the deformation of the hinge portion are bent in one direction, so that the bending direction of the wire harness can be regulated. The bending angle can be regulated by the bending angle regulating projection. Therefore, the wiring harness can be routed in a narrow space in the bending operation range.

As described above, in the wiring structure of the wire harness according to the present invention, the U-shaped wiring portion of the caterpillar-type exterior material follows the back and forth movement of the slide sheet, and moves back and forth while moving the position of the curved portion back and forth. In addition, the support shaft member supported by the rotary clamp on the sheet attachment side of the exterior material rotates, and the sheet-side tip of the exterior material is turned from sideways to upward so that the curved portion of the caterpillar type exterior material It can be moved up and down in the direction of increasing curvature. By adding this vertical follow-up movement to the front-rear follow-up movement, the front-rear follow-up movement dimension can be reduced.
