This guide direction is along the guide direction of the sheet power supply device 1 . The first guide portion 2a and the second guide portion 2b have the same guiding direction, and are spaced apart in a direction orthogonal to the guiding direction. The same guiding direction means that the guiding direction is the same direction, and here refers to the first guiding direction in the guiding direction. Further, the direction orthogonal to the guiding direction includes a direction substantially orthogonal to the guiding direction, which is along the vertical direction of the sheet power supply device 1 . Therefore, the first guide portion 2a and the second guide portion 2b are formed in the case 2 with a space therebetween in the vertical direction. The first guide portion 2a and the second guide portion 2b are formed to extend in the guide direction, and the wiring material 5 is inserted therein.

The first guide portion 2a is positioned above the second guide portion 2b and is integrally connected to the second guide portion 2b via a connecting portion 2d in the vertical direction. The first guide portion 2a has a case-side first opening 20 at the end in the second guide direction. The second guide portion 2b is integrally connected to the third guide portion 2c at the end in the second guide direction. The third guide portion 2c is formed in a U shape when viewed from the width direction orthogonal to the guide direction. The third guide portion 2c has a case-side third opening 22 at the end on the guide direction side.

The case-side first opening 20 opens toward the second guide direction side. The case-side first opening 20 is formed in a rectangular shape when viewed from the second guide direction, and has a size that matches the cross-sectional size of one wiring member 5 .

The case-side second opening 21 is provided at the end of the case 2 on the guide direction side and opens toward the guide direction side. The case-side second opening 21 is formed in a rectangular shape when viewed from the guiding direction, and is larger than either the case-side first opening 20 or the case-side third opening 22 described later. big.

The case-side third opening 22 opens toward the guide direction side. The case-side third opening 22 is formed in a rectangular shape when viewed from the guiding direction, and has a size that matches the cross-sectional size of one wiring member 5 .

The case 2 has a case body 10, a cover 11, and an accommodation space 23 in which a part of the wiring material 5 is accommodated in its structural configuration.

The case main body 10 accommodates a part of the wiring material 5 inside. The case main body 10 has respective portions corresponding to the first guide portion 2a, the second guide portion 2b, and the third guide portion 2c of the case 2, each formed in a groove shape opening in one direction in the width direction. As shown in FIG. 3, the case body 10 has a body-side bracket 10a and a body-side mounting hole 10b at its lower end. The body-side bracket 10 a forms part of the bracket 3 in the case 2 . The body-side mounting hole 10b is a through-hole that penetrates the body-side bracket 10a in the plate thickness direction.

The cover 11 is arranged on one side of the case body 10 in the width direction. The cover 11 has substantially the same shape as the case main body 10 when viewed in the width direction, and closes the case-side fourth opening 24 in the case main body 10 as shown in FIG. As shown in FIG. 2, the cover 11 has a cover-side bracket 11a and a cover-side mounting hole 11b at its lower end. The cover-side bracket 11 a constitutes another part of the bracket 3 in the case 2 . The cover-side mounting hole 11b is a through-hole that penetrates the cover-side bracket 11a in the plate thickness direction, and a fastening member is inserted through the cover-side mounting hole 11b while the case 2 is fixed to the slide rail 100 .

When the cover 11 closes the case-side fourth opening 24 , the housing space 23 is opened through the case-side first opening 20 , the case-side second opening 21 , and the case-side third opening 22 . It communicates with the outside. The first opening 20 on the case side, the second opening 21 on the case side, and the third opening 22 on the case side are arranged in an accommodated state in which part of the wiring material 5 is accommodated in the accommodation space 23 in the case 2. In both cases, the wiring material 5 is led out to the outside.

A portion of the wiring member 5 that is housed in the housing space 23 of the case 2 slides in the case 2 as the slide sheet moves in the sliding direction (hereinafter also referred to as "sliding movement"). A portion of the wiring member 5 that is housed in the case in the conventional seat power supply device is partially exposed to the outside of the case 2 . The wiring member 5 exposed to the outside from the case-side first opening 20 is wired toward the power transmission source described above. The wiring member 5 exposed to the outside from the case-side third opening 22 is routed through the inside of the slide rail 100 toward the power receiving destination on the slide seat. The wiring member 5 exposed to the outside from the case-side third opening 22 is not fixed to the case 2 in the middle of the wiring member 5 .

As shown in FIGS. 1 to 3, the wiring member 5 of the present embodiment is two straight portions among the portions housed in the case in the conventional seat power supply device along with the sliding movement. The first straight portion 5a, the second straight portion 5b, and one folded portion 5c are exposed to the outside from the case 2 on the first guide direction side.

The first straight portion 5a, the second straight portion 5b, and the folded portion 5c are arranged in the wiring member 5 from one side to the other in the extending direction of the wiring member 5 to form the first straight portion 5a, the folded portion 5c, and the second straight portion 5c. It is a portion that continues in the order of the two straight line portions 5b. The ends of the first straight portion 5a and the second straight portion 5b in the first guiding direction are connected via the folded portion 5c.

The first linear portion 5a is a portion that extends in the extending direction from the first guide portion 2a, and along with the sliding movement, extends from the accommodation space portion 23 inside the case 2 to the outside through the case-side second opening portion 21. This is the exposed part. Here, the extending direction is along the guiding direction of the sheet power supply device 1 in the housed state. The first linear portion 5a maintains a linear state in the extending direction regardless of the sliding movement.

The second linear portion 5b is a portion that extends in the extending direction from the second guide portion 2b, and along with the sliding movement, the second linear portion 5b is extended from the accommodation space portion 23 in the case 2 to the outside through the case-side second opening portion 21. This is the part exposed to The second linear portion 5b maintains a linear state in the extending direction regardless of the sliding movement.

The folded portion 5c is a portion that is folded back from the end in the extending direction of the first straight portion 5a and connected to the end in the extending direction of the second straight portion 5b. It is a portion exposed to the outside from the portion 23 through the case-side second opening portion 21 . The folded portion 5c is formed in a U shape when viewed in the width direction, and maintains an arc state having a constant curvature regardless of the sliding movement.

The wiring member 5 is composed of a plurality of feeder lines W, a belt-shaped member 30 and a holding member 31 .

The power supply line W is, for example, an electric wire for supplying power to a power receiving destination provided on the slide sheet. This electric wire has, for example, a conductor portion (core wire) made up of a plurality of conductive metal wires, and the outside thereof is covered with an insulating covering portion. The power supply line W has a circular cross-sectional shape at least at the portion housed in the housing space 23 of the case 2 . In this embodiment, a plurality of feeder lines W are bundled to form a wire bundle.

The belt-shaped member 30 is made of, for example, a belt-shaped thin metal plate, is formed to extend in an extension direction (for example, the X direction shown in FIG. 4), and is slightly curved at least in part when viewed from the extension direction. formed by As shown in FIG. 4, the strip-shaped member 30 of the present embodiment has a cross-sectional shape that is different from that of a simple flat plate. Each portion has a bent portion 30a. The belt-like member 30 is elastically deformable in the plate thickness direction (the Z direction shown in FIG. 4) orthogonal to the extending direction and the width direction, like the steel material of a so-called steel tape measure (convex). For example, even if the belt-shaped member 30 is bent from a straight shape to an arc shape by applying an external force, when the applied external force is released, the elastic restoring force restores the straight shape from the arc shape. The belt-like member 30 is in direct contact with the plurality of feeder lines W and arranged outside the plurality of feeder lines W. As shown in FIG. That is, the belt-shaped member 30 is positioned above the feeder line W at the first straight portion 5a, below the second straight portion 5b, and on the extension side at the folded portion 5c.

Both of the two bent portions 30a are bent toward one side in the plate thickness direction (for example, the X1 direction shown in FIG. 4) when viewed from the extending direction. The bent portion 30a is a portion of the band-shaped member 30 that is slightly curved. In the strip-shaped member 30, the linear portion in the width direction has a contact surface 30b that is a flat surface at the first straight portion 5a and the second straight portion 5b with respect to the plurality of power supply lines W arranged in the width direction. facing each other and in contact with a plurality of feeder lines W.

The holding member 31 holds the plurality of power supply lines W on the belt-shaped member 30 so as to follow the shape change of the belt-shaped member 30 . The holding member 31 is formed in a cylindrical shape, and the plurality of power supply lines W and the belt-shaped member 30 are inserted inside. The holding member 31 has flexibility and is configured by, for example, a tube woven with fibers. Here, the change in shape of the belt-like member 30 includes elastic deformation of the belt-like member from a linear shape to a circular arc shape and elastic restoration from the circular arc shape to a linear shape as the belt-like member slides. The holding member 31 protects the plurality of power supply lines W and the belt-shaped member 30 that are inserted inside, and also prevents the plurality of power supply lines W and the belt-shaped member 30 from coming apart or moving differently as they slide. to hold.

The first straight portion 5a and the second straight portion 5b are maintained at a constant distance in the vertical direction by the first guide portion 2a and the second guide portion 2b, and the belt-like member 30, regardless of the sliding movement, and are aligned in the extending direction. is maintained. The folded portion 5c is maintained in an arc state having a constant curvature by the first guide portion 2a, the second guide portion 2b, and the belt-like member 30 regardless of the sliding movement.

Next, state changes accompanying sliding movement of the first straight portion 5a, the second straight portion 5b, and the folded portion 5c of the wiring member 5 will be described. When part of the wiring member 5 is pulled out to the outside of the case 2 through the case-side third opening 22 as a result of the sliding movement, the wiring member 5 is moved to the first straight portion as shown in FIG. 5a, the second straight portion 5b, and the folded portion 5c are all accommodated in the case 2, which is the Min state. In the Min state, the length of the sheet power supply device 1 in the guiding direction is the shortest.

On the other hand, when a part of the wiring member 5 is most accommodated inside the case 2 through the case-side third opening 22 as the wiring member 5 slides, the first straight portion 5a and the second straight portion The Max state is reached in which the portion 5b is the longest in the guiding direction and is exposed to the outside of the case 2 . In the Max state, the length of the sheet power supply device 1 in the guiding direction is the longest.

The wiring member 5 of the present embodiment transitions from the Min state to the Max state via the Mid state, which is an intermediate state between the Min state and the Max state, according to the sliding movement, and the seat power supply device 1 length in the guiding direction. In this case, when part of the wiring member 5 is sent out from the second guide portion 2b through the second opening 21 on the case side in the first guide direction, the second straight portion 5b gradually moves in the first guide direction. , and the linear portion of the second linear portion 5b gradually curves while moving in the first guide direction to form an arcuate folded portion 5c having a constant curvature. Furthermore, when a part of the wiring member 5 is sent out from the second guide portion 2b in the first guide direction, the arc-shaped portion at the folded portion 5c gradually becomes straight, and the first straight portion 5a is changed. While forming, the first linear portion 5a gradually becomes longer in the first guiding direction.

On the other hand, the wiring member 5 of the present embodiment transitions from the Max state to the Min state via the Mid state according to the sliding movement, and the length of the sheet power supply device 1 in the guiding direction is shortened. In this case, when the second straight portion 5b is gradually accommodated in the second guide portion 2b through the second opening 21 on the case side, the second straight portion 5b becomes gradually shorter, and the first straight portion 5a becomes straight. The curved portion gradually curves to form an arcuate folded portion 5c having a constant curvature. Furthermore, when the second straight portion 5b is accommodated in the second guide portion 2b, the arc-shaped portion of the folded portion 5c gradually becomes straight while moving in the second guide direction, and the second straight portion 5b , the second straight portion 5b gradually shortens in the second guide direction.

As described above, in the sheet power supply device 1 according to the present embodiment, the case 2 that accommodates a portion of the wiring member 5 guides a portion of the wiring member 5 in the middle of the wiring member 5. It has a first guide portion 2a and a second guide portion 2b. The first guide portion 2a and the second guide portion 2b both extend in the same extension direction and are spaced apart in a direction orthogonal to the extension direction. The wiring member 5 is composed of a plurality of power supply lines W, a belt-shaped member 30, and a holding member 31 that holds the power supply lines W to the belt-shaped member 30 so as to follow the shape change of the belt-shaped member 30. The belt-shaped member 30 is made of a belt-shaped thin metal plate, similar to a so-called steel tape measure (convex), is formed to extend in the extension direction, and is formed to be partially curved when viewed from the extension direction. be done. The wiring material 5 includes a first straight portion 5a extending in the extending direction from the first guide portion 2a, a second straight portion 5b extending in the extending direction from the second guide portion 2b, and the first straight portion 5a. It has a folded portion 5c that folds back from the end in the extending direction and connects to the end in the extending direction of the second linear portion 5b.

With the above configuration, the case of a conventional power supply device for a seat does not require a portion that accommodates a wire harness that is covered with a corrugated tube while being bent in a U-shape, so that the mounting space for the case can be reduced. It is possible to save the space of the case. In addition, since a part of the case of the conventional seat power supply device can be made smaller, the weight of the case can be reduced. In the conventional seat power supply device, the corrugated tube through which the wire harness is inserted is housed in the case while being bent in a U-shape. Although there is a risk of generating abnormal noise, the first straight portion 5a, the second linear portion 5b, and the folded portion 5c do not hit the case 2 even if they vibrate, so the generation of abnormal noise can be suppressed. In addition, since there is no need to newly design a case according to the size and shape of the mounting space provided on the vehicle body side, the versatility of the seat power supply device 1 is improved, and the product cost can be reduced. It becomes possible.

Further, in the sheet power supply device 1 according to the present embodiment, the first straight portion 5a and the second straight portion 5b of the wiring member 5 are straightened along the same direction by the first guide portion 2a and the second guide portion 2b. By the belt-like member 30, the folded portion 5c can be maintained in an arc state having a constant curvature.

In addition, in the sheet power supply device 1 according to the present embodiment, the wiring member 5, the first straight portion 5a, the second straight portion 5b, and the folded portion 5c move along with the slide movement of the slide sheet to move the first guide portion. It is exposed to the outside of the case 2 from 2a and the second guide portion 2b. As a result, there is no need for a portion of the case of the conventional power supply device for a seat that accommodates the wire harness with the corrugated tube exterior bent in a U-shape, so that the mounting space for the case can be reduced. space can be saved.

Further, in the sheet power supply device 1 according to the present embodiment, the belt-like member 30 has bent portions 30a at both ends in the width direction orthogonal to the extending direction when viewed from the extending direction. As a result, the belt-shaped member 30 can ensure flexibility and uprightness at the same time as a convex having an arcuate cross-sectional shape when viewed in the extending direction.

In the above-described embodiment, the belt-like member 30 is formed to be partially curved when viewed in the extending direction.

It may be formed in an arc shape. In other words, the belt-like member may be entirely curved when viewed from the extending direction, like the belt-like member 30A. The belt-shaped member 30 has contact surfaces 30Aa, which are concave surfaces at the first straight portion 5a and the second straight portion 5b, facing the plurality of power supply lines W arranged in the width direction in the plate thickness direction. are in contact with In the sheet power supply device 1 according to the present embodiment, the cross-sectional shape of the belt-shaped member 30A when viewed from the extending direction is formed in an arc shape so as to expand toward one side in the plate thickness direction of the belt-shaped member 30A. . As a result, the belt-shaped member 30A can ensure flexibility and uprightness at the same time as a convex having an arcuate cross-sectional shape when viewed in the extending direction.

Moreover, in the above embodiment, the belt-like members 30 and 30A are composed of one thin metal plate, but are not limited to this, and may be composed of a laminate of a plurality of thin metal plates. When the belt-like members 30 and 30A are made of a plurality of thin metal plates, the plate thickness is preferably thinner than that of a single thin metal plate.

Further, the belt-shaped members 30 and 30A are arranged outside the plurality of power supply lines W, but are not limited to this, and may be arranged inside the plurality of power supply lines W. FIG. In this case, the belt-like members 30 and 30A are positioned on the lower side of the first straight portion 5a, on the upper side of the second straight portion 5b, and on the contraction side of the folded portion 5c.

In the above-described embodiment, the holding member 31 is formed in a tubular shape, is flexible, and is a tube woven with fibers into which the plurality of power supply lines W and the belt-shaped member 30 can be inserted. As long as the power supply line W is held so as to follow the change in shape of the belt-like member 30, it is not limited to this. For example, the configuration may be such that a plurality of feeder lines W and strip members 30 are bound with a plurality of binding bands. In this case, there is a configuration in which a plurality of locations to be bound with a binding band are provided at equal intervals along the extending direction of the plurality of power supply lines W and the belt-shaped member 30 .
