BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wire routing structure for a flexible flat cable for supplying power to a slide seat that is slidably supported along a longitudinal direction of a fixed rail fixed to a vehicle body in a vehicle such as an automobile. .

In recent years, in vehicles such as automobiles, electricity is supplied to the slide seat from the vehicle body side by, for example, electrifying the slide seat or attaching electrical components to the slide seat.
For example, in Patent Document 1, a seat-side electric wire provided on the slide seat side slidably supported along the longitudinal direction of a fixed rail (slide rail) fixed to the vehicle body, and a vehicle-side electric wire provided on the vehicle body side A power supply device is disclosed which is connected to an electric wire by a belt-shaped electric wire (flexible flat cable).

SUMMARY OF THE INVENTION In view of the above problems, it is an object of the present invention to provide an electric wire routing structure capable of suppressing damage to strip-like electric wires caused by advancing and retracting a slide seat.

This invention is a fixed rail that is fixed to a vehicle body by wiring a belt-shaped electric wire having one end electrically connected to a vehicle body side electric wire and the other end electrically connected to a seat side electric wire. A wire routing structure for supplying electricity to a slide seat that is slidably supported along a direction, is arranged along the fixed rail, and accommodates the strip-like wire along the longitudinal direction. A storage case and a holding member that holds the lead-out portion of the strip-shaped electric wire pulled out from the storage case are provided, and the holding member follows the advancing and retreating of the slide sheet in the storage case and moves in the longitudinal direction. wherein the storage case has a base for holding the one end of the strip-shaped electric wire, and an opening extending in the longitudinal direction and through which the holding member advances and retreats, The belt-shaped electric wire is formed to have a length that can follow the advance and retreat of the holding member.

The belt-shaped electric wire is a flexible flat cable in which a plurality of conductors arranged side by side are sandwiched between insulating sheets, or a flat cable in which a plurality of covered electric wires having a round cross section are arranged side by side.

According to the present invention, the wire routing structure can suppress damage to the belt-shaped wires accompanying the advance and retreat of the slide seat.
Specifically, since the holding member is configured to move forward and backward through the opening of the storage case rather than through the slit of the fixed rail, the wire wiring structure has a wider holding member than the slider that supports the slide seat. It can be formed narrow.

Therefore, the wire routing structure can form the opening of the storage case with a width narrower than the slit of the fixed rail. As a result, the wire routing structure can prevent foreign matter from entering the interior of the storage case compared to the fixed rail.

Furthermore, since the strip-shaped electric wires housed in the housing case are held by the base of the housing case and the holding member, the wire routing structure reciprocates between the fixed rail and the housing case as the slide seat advances and retreats. I have nothing to do. Therefore, the wire routing structure can prevent damage to the strip-like wire due to sliding on the fixed rail.

Therefore, the electric wire routing structure can suppress damage to the belt-shaped electric wire due to the advance and retreat of the slide seat. In addition, since damage to the belt-shaped electric wire can be suppressed, the electric wire routing structure does not require a protective tube for protecting the belt-shaped electric wire, for example, and can reduce the number of parts.

As a mode of this invention, the opening of the storage case may be opened upward of the storage case.
According to this configuration, even if the holding member tilts in the longitudinal direction as the slide seat advances and retreats, the wire routing structure prevents the holding member from coming into contact with the edge of the opening.

As a result, the wire routing structure can smoothly slide the holding member in the longitudinal direction following the advance and retreat of the slide seat. Therefore, the wire routing structure can prevent the belt-like wire from unintentionally bending due to, for example, the smooth sliding movement of the holding member being hindered.
Therefore, the wire routing structure can further prevent damage to the strip-like wire due to the advance and retreat of the slide seat.

Further, as a mode of the present invention, the opening of the storage case may open toward one side of the storage case in a substantially horizontal direction.
According to this configuration, the wire routing structure can prevent foreign matter from entering the interior of the storage case from above, compared to, for example, an opening that opens upward. Therefore, the wire routing structure can suppress damage to the belt-shaped wire caused by sliding against foreign matter inside the housing case.

Further, as an aspect of the present invention, in the housing case, the strip-shaped electric wire is housed in a U-shape in which a portion held by the base portion of the housing case and the lead-out portion are bent back at a bending portion. The storage case is provided with a case-side bending restricting portion that protrudes toward the bent-back portion side of the belt-shaped electric wire on the inner side of the U-shape in the vicinity of the base portion and restricts bending of the belt-shaped electric wire. The holding member is provided with a holding-member-side bending restricting portion that protrudes toward the bent-back portion side of the strip-shaped electric wire inside the U-shape of the strip-shaped electric wire and restricts bending of the strip-shaped electric wire. good too.

Restricting the bending of the strip-like electric wire means restricting the radius of curvature of the bent back portion from falling below a predetermined value.
According to this configuration, the wire routing structure can further suppress damage to the strip-like electric wire due to the advancing and retreating of the slide seat, and can stably ensure the electrical conductivity of the strip-like electric wire.

Specifically, since the strip-shaped electric wire does not reciprocate between the fixed rail and the housing case, the length of the portion of the strip-shaped electric wire housed in the housing case changes as the slide seat advances and retreats. never

Therefore, inside the storage case, the bent portion of the strip-shaped electric wire is deformed such that the radius of curvature gradually changes as the holding member advances and retreats.
At this time, in the wire routing structure, the holding member-side bending restricting portion and the case-side bending restricting portion can restrict the change in the radius of curvature of the bent back portion.

For example, when the holding member moves toward the bent-back portion, the wire routing structure is such that the curvature radius of the bent-back portion becomes extremely small due to the holding-member-side bending regulating portion, or the wire routing structure becomes strip-shaped starting from the vicinity of the holding member. It is possible to prevent the electric wire from bending.

On the other hand, when the holding member moves to the opposite side of the bent back portion, the wire routing structure is such that the curvature radius of the bent back portion becomes extremely small due to the case-side bending restricting portion, or the belt-shaped wire starts from the vicinity of the base. can be prevented from bending.
As a result, the wire routing structure can further suppress damage to the strip-like wires due to the advancing and retreating of the slide seat, and can stably ensure the electrical conductivity of the strip-like wires.

Further, as an aspect of the present invention, the housing case is arranged on the bent-back portion side of the belt-shaped electric wire relative to the base, for the belt-shaped electric wire routed from the base toward one of the longitudinal directions. Inclined wall portions facing each other in the thickness direction of the strip-like electric wire may be provided, and the inclined wall portions may gradually approach the facing surface portions facing the inclined wall portions toward one side in the longitudinal direction.

According to this configuration, the wire routing structure can gradually shorten the length of the storage case in the thickness direction on one side of the base portion in the longitudinal direction toward the one side of the longitudinal direction.
Furthermore, the radius of curvature of the bent portion of the strip-like electric wire becomes smaller as the holding member moves toward one side in the longitudinal direction.

Therefore, in the electric wire routing structure, the forward/backward movement of the holding member is not hindered by the contact between the inclined wall portion and the belt-shaped electric wire.
Therefore, the electric wire routing structure can reduce the size of the storage case without hindering the smooth movement of the holding member.

Further, as an aspect of the present invention, a direction opposite to the longitudinal direction from the base portion to the bent-back portion is defined as the other side in the longitudinal direction, and the storage case is arranged on the other side in the longitudinal direction relative to the base portion. A pair of side wall portions facing each other in the thickness direction of the strip-shaped electric wire routed along the longitudinal direction is provided, and among the pair of side wall portions, the side wall portion on the side of the base is more likely to be the holding member than the other portions. side wall portion.

According to this configuration, the wire routing structure can reduce the size of the storage case in the thickness direction on the other side in the longitudinal direction of the base. Therefore, the electric wire routing structure can suppress damage to the belt-shaped electric wire and further reduce the size of the storage case.

Further, as an aspect of the present invention, in the housing case, the strip-shaped electric wire is arranged such that a portion between the portion held by the base of the housing case and the lead-out portion extends from the base toward one side in the longitudinal direction. After being routed, it is bent back at the first bending portion, and is housed in a state in which it is routed from the first bending portion toward the other side in the longitudinal direction and then bent back at the second bending portion. The housing case protrudes toward the first bent portion side of the belt-shaped electric wire in the vicinity of the base portion on the base side of the belt-shaped electric wire bent back at the first bent-back portion, A case-side bending restricting portion for restricting bending of the belt-shaped electric wire is provided, and the holding member is configured to prevent the second bending of the belt-shaped electric wire on the side of the holding member of the belt-shaped electric wire that has been bent back at the second bend-return portion. A holding member-side bending restricting portion may be provided that protrudes toward the return portion and restricts bending of the strip-shaped electric wire.

According to this configuration, when the holding member moves toward the second bent portion, the wire routing structure is regulated by the case-side bending restricting portion and the holding member-side bending restricting portion. It is possible to prevent the radius of curvature of the bent portion from becoming extremely small.

Alternatively, when the holding member moves toward the second bent portion, the wire routing structure can prevent the belt-shaped electric wire from bending starting from the vicinity of the base and the holding member.
As a result, the wire routing structure can further suppress damage to the strip-like wires due to the advancing and retreating of the slide seat, and can stably ensure the electrical conductivity of the strip-like wires.

Further, as an aspect of the present invention, the base may be arranged at an intermediate position in the longitudinal direction of the storage case.
According to this configuration, the wire routing structure can reduce the total length of the strip-shaped wire compared to the case where the base is provided near one end of the storage case in the longitudinal direction, so that the weight increase can be suppressed.

Further, as an aspect of the present invention, a plurality of the strip-shaped electric wires are laminated in a thickness direction, and a plurality of the holding members are arranged along the longitudinal direction, and at least one of the laminated strip-shaped electric wires is The configuration may be such that they are held respectively.

The plurality of holding members refer to, for example, a plurality of holding members that can advance and retreat following one slide sheet, or a plurality of holding members that can advance and retreat following different slide sheets.

According to this configuration, the plurality of holding members for holding at least one strip-shaped electric wire allows the wire connection structure to hold the plurality of strip-shaped wires housed in one storage case in a sheet arranged at different positions in the longitudinal direction. Can be connected to the side wire.

For example, when two holding members are provided that can move back and forth following one slide seat, the wire routing structure consists of a seat-side wire provided near the front leg of the slide seat and a wire provided near the rear leg of the slide seat. A plurality of strip-shaped electric wires housed in one housing case can be connected to the sheet-side electric wires.

Alternatively, if a first holding member that can move forward and backward following one of two slide seats arranged on a fixed rail and a second holding member that can move forward and backward following the other slide seat are used, the wire distribution system can be used. The cable structure can connect a plurality of strip-like electric wires housed in one housing case to a seat-side electric wire provided on one slide seat and a seat-side electric wire provided on the other slide seat.

Thereby, the electric wire routing structure can supply electricity to the seat-side electric wires arranged at different positions in the longitudinal direction without providing a plurality of storage cases. Therefore, the wire routing structure can prevent the limited space in the passenger compartment from being squeezed by a plurality of storage cases.

Further, as an aspect of the present invention, the strip-shaped electric wire may be arranged so that the thickness direction thereof is substantially vertical in the housing case.
According to this configuration, for example, even when a plurality of strip-shaped wires are stacked in the thickness direction, the wire routing structure can keep the length of the storage case constant in the horizontal direction.

As a result, even when a plurality of belt-shaped electric wires are housed in the housing case, the wire routing structure can suppress the size of the housing case in the horizontal direction. can be prevented.

Further, as an aspect of the present invention, the strip-shaped electric wire may be arranged so that the thickness direction thereof is substantially horizontal in the housing case.

It is Further, the body portion 91 is formed so that the lead-out portion 40b of the cable routing body 40 can be led out from the upper end toward the other side in the width direction Y. As shown in FIG.

As shown in FIGS. 1 and 2 , the connecting portion 92 extends from the upper end of the body portion 91 toward the other side in the width direction Y and is connected to the front portion of the slider 3 . Furthermore, as shown in FIG. 2, the seat-side wire connecting portion 50 is mounted and fixed to the connecting portion 92 by an appropriate means.

As shown in FIGS. 2 and 3, the holding member-side bending restricting portion 93 is integrally formed at the lower end of the main body portion 91, and the cable routing body 40 is bent so that the bent return portion 40a does not fall below a desired radius of curvature. It is configured to be able to regulate bending.

Specifically, as shown in FIGS. 2 and 3 , the holding member-side bending restricting portion 93 protrudes forward in the direction toward the bending return portion 40 a of the cable routing body 40 , that is, in a side view. It is formed in a shape having a semicircular arc surface on the front surface.
The arcuate surface of the holding member-side bending restricting portion 93 is formed in a substantially semicircular shape having substantially the same diameter as the arcuate surface of the case-side bending restricting portion 817 .

Next, a state in which the slide seat 4 has moved most forward and a state in which the slide seat 4 has moved most rearward in the power supply device 5 configured as described above will be described with reference to FIGS. 5 and 6. FIG.
5 is an explanatory diagram for explaining the state of the cable routing body 40 with the slide seat 4 moved forward, and FIG. 6 is the state of the cable routing body 40 with the slide seat 4 moved backward. is an explanatory diagram for explaining the .

First, when the slide seat 4 starts to move forward, the holding member 90 of the power supply device 5 follows the forward movement of the slide seat 4 and moves toward the opening 80a of the storage case 80, as shown in FIG. move forward along the

At this time, the bent back portion 40a of the cable routing body 40 is deformed such that the radius of curvature gradually decreases as the holding member 90 moves forward, and the holding member side bending restricting portion 93 of the holding member 90 is deformed. Start contact.
Then, as shown in FIG. 5, the bent back portion 40a of the cable routing body 40 is deformed into a shape along the arcuate surface of the holding member side bending restricting portion 93 in the state where the slide seat 4 is moved to the most forward direction. .

In other words, the bent-back portion 40a of the cable routing body 40 is regulated by the holding-member-side bending regulating portion 93, and has the smallest radius of curvature.
At this time, the cable routing body 40 is in a routing state in which the portion between the lower end of the bent-back portion 40a and the base portion 816 extends substantially linearly.

On the other hand, when the slide seat 4 starts to move rearward, the holding member 90 of the power supply device 5 follows the rearward movement of the slide seat 4 to move toward the opening 80a of the storage case 80, as shown in FIG. move backward along the

At this time, the bent back portion 40 a of the cable routing body 40 is deformed such that the radius of curvature gradually decreases as the holding member 90 moves rearward, and contacts the case-side bending restricting portion 817 of the storage case 80 . Start.
Then, as shown in FIG. 6, the bent back portion 40a of the cable routing body 40 is deformed into a shape along the arcuate surface of the case-side bend restricting portion 817 when the slide seat 4 is moved to the rearmost position.

That is, the bent-back portion 40a of the cable routing body 40 is regulated by the case-side bending regulating portion 817, and has the smallest radius of curvature.
At this time, the cable routing body 40 is in a routing state in which the upper end of the bent-back portion 40a and the holding member 90 extend substantially linearly.

As described above, the wire routing structure of the present embodiment is a cable having one end electrically connected to the vehicle body side wire harness 6 and the other end electrically connected to the seat side wire harness 7. Electricity is supplied to the slide seat 4 which is slidably supported along the front-rear direction X of the fixed rail 2 fixed to the vehicle body by wiring the wiring body 40 .

This electric wire wiring structure is arranged along the fixed rail 2 and includes a housing case 80 that houses the cable wiring body 40 along the front-rear direction X, and a pull-out portion of the cable wiring body 40 pulled out from the housing case 80. A holding member 90 for holding 40b is provided.
Further, the holding member 90 is configured to be able to advance and retreat in the front-rear direction X by following the advance and retreat of the slide seat 4 within the accommodation case 80 .

Furthermore, the housing case 80 is provided with a base portion 816 that holds one end of the cable routing body 40, and an opening portion 80a that extends in the front-rear direction X and opens and allows the holding member 90 to advance and retreat. is.
The cable routing body 40 is formed with a length that can follow the advance and retreat of the holding member 90 .

According to this, the wire routing structure can suppress damage to the cable routing body 40 accompanying the advance and retreat of the slide seat 4 .
Specifically, since the holding member 90 is configured to move back and forth through the opening 80a of the storage case 80 instead of through the slit of the fixed rail 2, the wire routing structure is reduced compared to the slider 3 that supports the slide seat 4. Therefore, the holding member 90 can be formed narrow.

Therefore, the wire routing structure can form the opening 80 a of the storage case 80 with a size narrower than the slit of the fixed rail 2 . As a result, the wire routing structure can suppress entry of foreign matter into the storage case 80 compared to the fixed rail 2 .

Furthermore, since the cable wiring body 40 housed in the housing case 80 is held by the base portion 816 of the housing case 80 and the holding member 90, the wire wiring structure is configured such that the fixed rail 2 moves forward and backward as the slide seat 4 advances and retreats. and housing case 80. Therefore, the wire routing structure can prevent the cable routing body 40 from being damaged due to sliding against the fixed rail 2 .

Therefore, the wire routing structure can suppress damage to the cable routing body 40 accompanying the advance and retreat of the slide seat 4 . In addition, since damage to the cable routing body 40 can be suppressed, the wire routing structure does not require a protective tube that protects the cable routing body 40, for example, and the number of parts can be reduced.

Further, the opening 80a of the storage case 80 is opened toward the upper side of the storage case 80. As shown in FIG.
According to this configuration, even when the holding member 90 is tilted in the front-rear direction X as the slide seat 4 advances and retreats, the wire routing structure allows the holding member 90 to contact the edge of the opening 80a. never

As a result, the wire routing structure can smoothly slide the holding member 90 in the front-rear direction X following the advance and retreat of the slide seat 4 . Therefore, the wire routing structure can prevent the cable routing body 40 from unintentionally bending due to obstruction of the smooth sliding movement of the holding member 90, for example.
Therefore, the wire routing structure can further prevent the cable routing body 40 from being damaged as the slide seat 4 advances and retreats.

Further, in the housing case 80, the cable routing body 40 is housed in a U-shape in which the portion held by the base portion 816 of the housing case 80 and the lead-out portion 40b are bent back at the bent-back portion 40a. there is

Further, the housing case 80 has a case-side bending restricting portion that protrudes toward the bending return portion 40a side of the cable routing body 40 on the inner side of the U shape near the base portion 816 and restricts bending of the cable routing body 40. 817 is provided.

In addition, the holding member 90 protrudes toward the side of the bending portion 40a of the cable routing body 40 inside the U-shape of the cable routing body 40, and is on the side of the holding member that restricts bending of the cable routing body 40. A bending restricting portion 93 is provided.

According to this configuration, the wire routing structure can further suppress damage to the cable routing body 40 due to the advancing and retreating of the slide seat 4, and can stably ensure the electrical conductivity of the cable routing body 40. FIG.

Specifically, since the cable routing body 40 does not reciprocate between the fixed rail 2 and the storage case 80, the length of the portion of the cable routing body 40 that accommodates the storage case 80 is It does not change as the slide seat 4 advances and retreats.

Therefore, inside the housing case 80 , the bent-back portion 40 a of the cable routing body 40 is deformed such that the radius of curvature gradually changes as the holding member 90 advances and retreats.
At this time, in the wire routing structure, the holding member side bending restricting portion 93 and the case side bending restricting portion 817 can restrict the change in the radius of curvature of the bent return portion 40a.

For example, when the holding member 90 moves toward the bent portion 40a, the holding member-side bending restricting portion 93 of the wire routing structure causes the curvature radius of the bent portion 40a to become extremely small, or the holding member 90 It is possible to prevent the cable routing body 40 from bending from the vicinity thereof as a starting point.

On the other hand, when the holding member 90 moves to the opposite side of the bent back portion 40a, the case-side bend restricting portion 817 of the wire routing structure causes the curvature radius of the bent back portion 40a to become extremely small, or It is possible to prevent the cable routing body 40 from bending from the starting point.
As a result, the wire routing structure can further suppress damage to the cable routing body 40 due to the advancing and retreating of the slide seat 4, and can stably ensure the electrical conductivity of the cable routing body 40. FIG.

In addition, the storage case 80 is positioned closer to the bent-back portion 40a of the cable routing body 40 than the base portion 816, and the cable routing body 40 is placed in the cable routing body 40 routed forward from the base portion 816. Inclined portions 815a are provided that face each other in the thickness direction. The inclined portion 815a gradually approaches the upper surface portion 814 toward the front.

According to this configuration, the wire routing structure can gradually shorten the length of the storage case 80 in the thickness direction forward of the base portion 816 toward the front.
Furthermore, the radius of curvature of the bent back portion 40a of the cable routing body 40 becomes smaller as the holding member 90 goes forward.

Therefore, in the electric wire routing structure, contact between the inclined portion 815a and the cable routing body 40 does not impede forward and backward movement of the holding member 90 .
Therefore, the electric wire routing structure can reduce the size of the storage case 80 without hindering the smooth movement of the holding member 90 .

Further, the storage case 80 is provided with a top surface portion 814 and a bottom surface portion 815 facing each other in the thickness direction of the cable routing body 40 routed along the front-rear direction X behind the base portion 816 . Of the top surface portion 814 and the bottom surface portion 815, the bottom surface portion 815 is closer to the top surface portion 814 than the other portions.

According to this configuration, the wire routing structure can reduce the size of the storage case 80 in the thickness direction behind the base portion 816 . Therefore, the wire routing structure can suppress damage to the cable routing body 40 and further reduce the size of the housing case 80 .

Also, the base portion 816 is arranged at an intermediate position in the front-rear direction X of the storage case 80 .
According to this configuration, the wire routing structure can shorten the total length of the cable routing body 40 compared to the case where the base portion 816 is provided near one end of the housing case 80 in the front-rear direction X, thereby suppressing an increase in weight. can.

In addition, the cable routing body 40 is arranged inside the housing case 80 such that the thickness direction thereof is substantially vertical (vertical direction).
According to this configuration, for example, even when a plurality of flexible flat cables 41 are stacked in the thickness direction, the wire routing structure can keep the length of the housing case 80 constant in the horizontal direction (width direction Y).

As a result, even when a plurality of flexible flat cables 41 are accommodated in the accommodation case 80, the wire routing structure can suppress the size of the accommodation case 80 in the horizontal direction, thereby increasing the degree of freedom in the layout of the vehicle interior. You can prevent it from being damaged.

Moreover, although the cable routing body 40 is arranged such that the thickness direction of the flexible flat cable 41 is the vertical direction inside the storage case 80 having a thickness in the width direction Y, the present invention is not limited to this.
For example, the cable routing body 40 may be arranged such that the thickness direction of the flexible flat cable 41 is the width direction Y inside a storage case having a thickness in the vertical direction. In this case, an opening through which the holding member slides is formed in the upper or side surface of the storage case.

According to this, since the cable routing body 40 is arranged so that the thickness direction of the flexible flat cable 41 becomes the width direction Y inside the storage case, the wire routing structure is formed by, for example, a plurality of flexible flat cables. 41 can be stacked in the thickness direction, the length of the storage case in the vertical direction (vertical direction) can be made constant.

As a result, even when a plurality of flexible flat cables 41 are housed in the housing case, the electric wire routing structure can suppress an increase in size of the housing case in the vertical direction. can be prevented.
