Description

This invention relates to a harness routing structure that supplies power from the vehicle body to electrical components built into a sliding seat.

Conventionally, automobiles have been equipped with sliding seats that can slide in the fore-and-aft direction, and these sliding seats incorporate electrical components such as seatbelt reminders and side airbag squibs. Therefore, it is necessary to supply power to these electrical components from the vehicle body (see Patent Documents 1 and 2).

However, when the sliding seat slides forward or backward, the harness stretching between the vehicle body and the sliding seat deforms, changing the harness path. This can cause the harness to bend locally (a curve with a large curvature, i.e., a sharp, sharp bend), which could potentially place an excessive load on the harness.

Japanese Patent Application Laid-Open No. 2017-158237 JP 2017-103890 A

The object of the present invention is to provide a harness routing structure that prevents excessive load from being applied to the harness even when the sliding seat slides forward and backward.

This invention is a harness routing structure that supplies power from a vehicle body to electrical components built into a sliding seat, and is provided with a harness that is spanned between the vehicle body and the sliding seat, and a harness guide portion that is attached to at least one of the vehicle body and the sliding seat and guides the harness, the harness guide portion having a main body portion that is attached to the vehicle body or the sliding seat and guides the harness, and a tip portion that is attached to the main body portion and guides the harness in a direction crossing a harness passage formed in the main body portion, and an enlarged fitting hole portion at the tip side portion of the harness passage is fitted with a cylindrical fitting tube portion formed at the base end side end of the tip portion, so that the tip portion is supported so as to be rotatable around the harness passage in the main body, and a spiral portion in which a portion of the harness is spiraled is accommodated in the harness passage in the main body portion on the base end side of the fitting hole portion .

According to this invention, even if the slide seat slides in the front-rear direction, an excessive load can be prevented from acting on the harness.
In more detail, according to the harness routing structure of the present invention, even if the sliding seat slides to one side in the front-to-rear direction and the harness route changes, the portion that guides the harness in the crossing direction rotates in response to the change in the harness route, thereby preventing the harness from bending locally. Also, even if the sliding seat slides to the other side in the front-to-rear direction and the harness route changes, the portion that guides the harness in the crossing direction rotates in response to the change in the harness route, thereby preventing the harness from bending locally. As a result, even if the sliding seat slides in the front-to-rear direction, excessive loads can be prevented from acting on the harness.

In addition, the harness guide portion has a main body portion attached to the vehicle body or the slide seat and guiding the harness, and a tip portion attached to the main body portion and guiding the harness in a direction intersecting the harness passage formed in the main body portion, and the tip portion is supported so as to be freely rotatable around the harness passage in the main body portion.

Therefore , even if the sliding seat slides to one side in the front-rear direction and the harness route changes, the tip portion rotates in response to the change in the harness route, preventing the harness from bending locally. Also, even if the sliding seat slides to the other side in the front-rear direction and the harness route changes, the tip portion rotates in response to the change in the harness route, preventing the harness from bending locally. Ultimately, even if the sliding seat slides in the front-rear direction, excessive loads can be prevented from being applied to the harness.

Furthermore, a spiral portion formed by spiraling a portion of the harness is accommodated in the harness passage in the main body on the base end side of the fitting hole.
Therefore, when the tip portion rotates, the number of turns or the winding diameter of the spiral portion of the harness where the main body is inserted increases or decreases. This configuration allows the spiral portion of the harness where the main body is inserted to absorb twisting. Therefore, the main body inserted portion of the harness can be prevented from twisting at a large torsion rate. Consequently, even when the sliding seat slides forward or backward, excessive loads can be prevented from acting on the main body inserted portion of the harness.
As an aspect of the present invention, the fitting hole may be provided with a restricting portion that restricts the fitting tubular portion from coming out of the fitting hole.

In another aspect of the present invention, the length of the harness passage in the main body may be longer than five times the outer diameter of the harness.
According to this invention, when the tip portion rotates, the main body insertion portion of the harness twists over the entire length of the passage. This configuration prevents localized twisting at the main body insertion portion of the harness. Therefore, the main body insertion portion of the harness can be prevented from twisting at a large torsion rate. Consequently, even when the sliding seat slides forward and backward, excessive loads can be prevented from acting on the main body insertion portion of the harness.

In another aspect of the present invention, the bending radius of the harness passage at the tip end may be greater than one time the outer diameter of the harness.
According to this invention, when the tip portion rotates, even if a pulling load or a pushing load is applied to the tip portion insertion portion of the harness, the bending radius is restricted. This configuration makes it possible to prevent localized bending of the tip portion insertion portion of the harness. Therefore, the tip portion insertion portion of the harness can be prevented from bending with a large curvature. Ultimately, even if the sliding seat slides in the front-rear direction, excessive load can be prevented from acting on the tip portion insertion portion of the harness.

In another aspect of the present invention, the tip end may be provided with a fitting portion that fits with an exterior part attached to the harness.
According to this invention, the portion of the harness extending from the distal end that is most likely to bend (the root portion of the harness extending from the distal end) can be supported by the exterior component fitted to the distal end. This prevents the portion of the harness extending from the distal end from being bent with a large curvature. Consequently, even when the sliding seat slides in the fore-and-aft direction, excessive loads can be prevented from being applied to the portion of the harness extending from the distal end.

In another aspect of the present invention, the harness may be bent back and routed parallel or substantially parallel to a floor panel that constitutes the vehicle body.
This invention allows the harness to be routed along the floor panel, reducing the space occupied in the direction toward or away from the floor panel, making it possible to route the harness even in places where the gap toward or away from the floor panel is narrow.

In another aspect of the present invention, the harness may be bent back and routed between a floor panel and the sliding seat that constitute the vehicle body.
This invention allows the harness to be housed between the floor panel and the sliding seat, which makes it possible to hide the harness from the view of the person sitting on the sliding seat and those around, thereby improving the aesthetic appearance.

In another aspect of the present invention, a protective cover portion may be provided to cover the harness guide portion, and an opening hole may be formed in the protective cover portion to allow the harness guide portion to pass through.
According to this invention, the harness guide can be protected by the protective cover, and the harness guide can be hidden from view of a person sitting on the sliding seat and those around, thereby improving the aesthetic appearance.

In another aspect of the present invention, a protective cap may be provided that is fitted onto the harness guide, and the protective cap may be fitted into the opening formed in the protective cover.
This invention can prevent water, dust, and the tip of the umbrella from getting in through the opening in the protective cover. It also makes it possible to improve the aesthetic appearance by preventing the inside from being seen through the opening in the protective cover.

According to the present invention, excessive loads can be prevented from acting on the harness even when the sliding seat slides forward and backward.

As shown in FIG. 1, a pair of seat rails 102 are fixed to a floor panel 101 that constitutes a vehicle body 100, and are parallel to the front-to-rear direction. A sliding seat 200 is placed on these seat rails 102. Therefore, the sliding seat 200 can slide in the front-to-rear direction along these seat rails 102.

As shown in FIG. 1, the harness routing structure 1 of the present invention supplies power from the vehicle body 100 to electrical components incorporated in the sliding seat 200. The harness routing structure 1 includes a harness 2, a harness guide portion 3, a protective cover portion 4, and a protective cap portion 5. Below, the harness 2 and harness guide portion 3 will be described, followed by a description of the protective cover portion 4 and the protective cap portion 5.

The harness 2 is stretched between the vehicle body 100 and the sliding seat 200. As shown in Figures 2 to 6, the harness 2 is composed of a bundle of insulated electric wires 21 and extends from an opening 10h provided in the floor panel 101. The harness 2 also has a connector 22 attached to its tip that houses terminal fittings crimped onto each insulated electric wire 21 (see Figure 1). The connector 22 is connected to a connector 220 of an electrical component incorporated in the sliding seat 200.

This configuration allows power to be supplied to the electrical components incorporated in the sliding seat 200. The connector 220 is attached to the left front end portion of the underside of the seat cushion 201 that constitutes the sliding seat 200 (see Figure 1). The connector 22 is connected to the connector 220 by pushing the sliding seat 200 from the front side toward the rear side. The harness 2 is fitted with a corrugated tube 23, which is an exterior component.

The harness guide 3 is attached to the vehicle body 100 and guides the harness 2. Specifically, it is attached to a floor panel 101 that constitutes the vehicle body 100, and guides the harness 2 that extends from an opening 10h in the floor panel 101. As shown in Figures 2 to 6, the harness guide 3 is mainly composed of a main body 31 and a tip 32, and the harness passage 31P of the main body 31 and the harness passage 32P of the tip 32 are connected (continuously) to form a single harness passage 3P.

The main body 31 has a cylindrical trunk 311. A harness passage 31P is formed in the trunk 311, penetrating from the base end to the tip end, and its passage length DL is designed to be greater than five times the outer diameter (bundle diameter) of the harness 2. The harness passage 31P is expanded in diameter at its tip end, forming a fitting hole 31h that fits with the fitting tubular portion 322 (described below). Two annular grooves 31g are formed on the inner surface of the fitting hole 31h, and a rubber ring 33 is housed in the lower annular groove 31g.

In addition, the main body 31 has a support plate 312 formed in a flat plate shape at the base end of the trunk 311. The support plate 312 has through holes 31t that penetrate vertically on both sides of the trunk 311. Therefore, the main body 31 is attached to the floor panel 101 with bolts 34 inserted into the through holes 31t. Note that when the main body 31 is attached to the floor panel 101, the harness passage 31P of the main body 31 is connected to (continuously connected with) the opening 10h of the floor panel 101. Therefore, the harness 2 extending from the opening 10h of the floor panel 101 can be guided in a direction perpendicular to the floor panel 101. This direction is the extension direction of the harness 2 in the harness routing structure 1.

The tip portion 32 has a curved tube portion 321 formed by bending a cylindrical body into an arc. The curved tube portion 321 has a harness passage 32P formed therein, penetrating from the base end to the tip end. The bend radius DR of the curved tube is designed to be greater than one times the outer diameter (bundle diameter) of the harness 2. The harness passage 32P is also enlarged in diameter at its tip end, forming a fitting hole 32h that fits with the corrugated tube 23 described above. The inner circumferential surface of the fitting hole 32h is provided with a locking claw 32c that protrudes radially inward and can be hooked onto the recessed groove of the corrugated tube 23 to lock it in place. Alternatively, the corrugated tube 23 and tip portion 32 may be secured together by wrapping a long piece of tape around them.

In addition, the tip portion 32 has a cylindrical fitting tube portion 322 formed at the base end of the curved tube portion 321. The fitting tube portion 322 has an upper end surface 32s that intersects perpendicularly with its outer circumferential surface, and this upper end surface 32s is located slightly below the upper annular groove 31g. Therefore, the tip portion 32 is attached to the main body portion 31 while being prevented from slipping out upward by a snap ring 35 fitted in the annular groove 31g. Note that when the tip portion 32 is attached to the main body portion 31, the harness passage 32P of the tip portion 32 is connected (continuously connected) to the harness passage 32P of the main body portion 31. Therefore, the harness 2 guided by the harness passage 31P of the main body portion 31 can be guided in a direction perpendicular to the harness passage 31P. This direction is the crossing direction of the harness 2 in the harness routing structure 1.

As shown in Figure 7, in the harness routing structure 1 according to this embodiment, the harness 2 extending from the tip end 32 is routed by bending it back and arranging it approximately parallel to the floor panel 101. Specifically, the harness 2 is routed between the floor panel 101 and the sliding seat 200 (seat cushion 201) while being bent back and slightly tilted relative to the floor panel 101. The harness 2 is slightly tilted in this manner to prevent water droplets from running down the harness 2 to the connector 22.

As shown in Figure 8, the harness 2 extending from the tip 32 extends diagonally rearward to the left, intersecting the sliding direction (front-rear direction) of the sliding seat 200. The harness 2 is then bent back toward the front. Therefore, point P, which is located at the rearmost point of the bent portion of the harness 2, is located rearward of the imaginary line V that passes through the harness guide 3 and extends in the left-right direction. The harness 2 is routed in this manner in order to change the harness path as follows:

That is, as shown in FIG. 9(a), when the sliding seat 200 is slid forward (see arrow Sf), the connector 22 moves away from the harness guide 3 attached to the floor panel 101, causing the bending radius of the bent portion of the harness 2 to gradually increase. At this time, the tip 32 of the harness guide 3 also rotates forward (see arrow Rf), preventing localized bending of the harness 2. Specifically, localized bending of the portion N of the harness 2 near the tip can be prevented.

It is important to design the sliding seat 200 so that the harness 2 does not stretch completely even when it is slid all the way forward. For this reason, a guide or the like may be provided along the harness path at this time. Also, a plate or the like may be provided to prevent the harness 2 from sagging. These may also be configured as an integrated unit.

Conversely, as shown in Figure 9(b), when the sliding seat 200 is slid rearward (see arrow Sb), the connector 22 approaches the harness guide 3 attached to the floor panel 101, causing the bending radius of the bent portion of the harness 2 to gradually decrease. At this time, the tip 32 of the harness guide 3 also rotates rearward (see arrow Rb), preventing localized bending of the harness 2. Specifically, localized bending of the portion N of the harness 2 near the tip can be prevented.

It is important to design the sliding seat 200 so that the harness path of the harness 2 is fixed even when it is slid all the way to the rear. For this reason, a guide or the like may be provided along the harness path at this time. Also, a plate or the like may be provided to prevent the harness 2 from sagging. These may be configured as an integrated unit.

Next, as shown in Figure 10, the protective cover portion 4 and protective cap portion 5 will be described. In the harness routing structure 1 according to this embodiment, these are made of a resin material such as polypropylene or polyethylene. However, they may also be made of aluminum or steel plate material. Furthermore, they may be integrated with the floor panel 101 or the like that constitutes the vehicle body 100. Alternatively, they may be integrated with an interior panel or the like that is attached to the floor panel 101 or the like.

The protective cover portion 4 has a front plate 41 and a rear plate 42 that face each other in the longitudinal direction, a right plate 43 and a left plate 44 that face each other in the lateral direction, and a top plate 45 that faces the floor panel 101 and intersects with the upper edges of the plates 41 to 44. A rectangular opening 45h is formed in the top plate 45, through which the tip portion 32 of the harness guide portion 3 is passed. It is important to design the top plate 45 so that even when the tip portion 32 rotates, neither the tip portion 32 nor the harness 2 (including the corrugated tube 23) extending from the tip portion 32 will interfere with the top plate 45, etc.

The protective cap 5 has a rectangular cover plate 51. A semicircular insertion hole 51h is formed in the cover plate 51, and the tip 32 of the harness guide 3 is passed through this insertion hole 51h, thereby becoming one with the tip 32. Locking claws 52 are provided along each edge of the underside of the cover plate 51. Therefore, by placing the protective cap 5 over the opening 45h of the protective cover 4 and pushing it in from above, the locking claws 52 can be hooked onto each edge of the opening 45h. This configuration allows the opening 45h of the protective cover 4 to be sealed.

As described above, the harness routing structure 1 supplies power from the vehicle body 100 to electrical components incorporated in the sliding seat 200. The harness routing structure 1 includes a harness 2 that is stretched between the vehicle body 100 and the sliding seat 200, and a harness guide 3 that is attached to the vehicle body 100 and guides the harness 2. The harness guide 3 guides the harness 2 that extends from the vehicle body 100 in a direction intersecting the extension direction, and the portion that guides the harness 2 in the intersecting direction (tip 32) is supported so that it can rotate freely.

According to this harness routing structure 1, even if the sliding seat 200 slides in the front-rear direction, an excessive load can be prevented from acting on the harness 2.
More specifically, according to the harness routing structure 1 of the present invention, even if the sliding seat 200 slides to one side in the front-to-rear direction and the harness route changes, the portion (tip portion 32) that guides the harness 2 in the crossing direction rotates in response to the change in the harness route, thereby preventing the harness 2 from bending locally. Also, even if the sliding seat 200 slides to the other side in the front-to-rear direction and the harness route changes, the portion (tip portion 32) that guides the harness 2 in the crossing direction rotates in response to the change in the harness route, thereby preventing the harness 2 from bending locally. Consequently, even if the sliding seat 200 slides in the front-to-rear direction, it is possible to prevent an excessive load from being applied to the harness 2.

In addition, in the harness routing structure 1 according to this embodiment, the harness guide 3 has a main body 31 that is attached to the vehicle body 100 and guides the harness 2, and a tip 32 that is attached to the main body 31 and guides the harness 2 in a direction intersecting the harness passage 31P formed in the main body 31, with the tip 32 supported so as to be rotatable around the harness passage 31P in the main body 31.

With this harness routing structure 1, even if the sliding seat 200 slides to one side in the fore-and-aft direction and the harness route changes, the tip portion 32 rotates in response to the change in the harness route, preventing the harness 2 from bending locally. Furthermore, even if the sliding seat 200 slides to the other side in the fore-and-aft direction and the harness route changes, the tip portion 32 rotates in response to the change in the harness route, preventing the harness 2 from bending locally. Consequently, even if the sliding seat 200 slides in the fore-and-aft direction, excessive loads can be prevented from being applied to the harness 2.

In the harness routing structure 1 according to this embodiment, the passage length DL of the harness passage 31P in the main body 31 is set to be longer than five times the outer diameter of the harness 2.
According to this harness routing structure 1, when the tip portion 32 rotates, the main body insertion portion of the harness 2 twists over the entire passage length DL. This configuration makes it possible to prevent localized twisting from occurring in the main body insertion portion of the harness 2. Therefore, the main body insertion portion of the harness 2 can be prevented from twisting at a large torsion rate. Consequently, even if the sliding seat 200 slides in the front-rear direction, it is possible to prevent excessive load from acting on the main body insertion portion of the harness 2.

In addition, in the harness routing structure 1 according to this embodiment, the bending radius DR of the harness passage 32P at the tip end portion 32 is set to be larger than one time the outer diameter of the harness 2.
According to this harness routing structure 1, when the tip 32 rotates, the bending radius is restricted even if a pulling load or a pushing load is applied to the tip insertion portion of the harness 2. This configuration makes it possible to prevent local bending of the tip insertion portion of the harness 2. Therefore, it is possible to prevent the tip insertion portion of the harness 2 from bending with a large curvature. Consequently, even if the sliding seat 200 slides in the front-rear direction, it is possible to prevent an excessive load from acting on the tip insertion portion of the harness 2.

In addition, in the harness routing structure 1 according to this embodiment, the end portion 32 is provided with a fitting hole portion 32h into which the corrugated tube 23 attached to the harness 2 is fitted.
According to this harness routing structure 1, the portion N near the tip (the base portion of the harness 2 extending from the tip 32), which is the portion of the harness 2 extending from the tip 32 that is most likely to bend, can be supported by the corrugated tube 23 fitted to the tip 32. This prevents the portion N near the tip of the harness 2 from bending with a large curvature. Consequently, even if the sliding seat 200 slides in the front-rear direction, it is possible to prevent an excessive load from being applied to the portion N near the tip of the harness 2.

In the harness routing structure 1 according to this embodiment, the harness 2 is routed by being bent back substantially parallel to the floor panel 101 that constitutes the vehicle body 100 .
According to this harness routing structure 1, the harness 2 is routed along the floor panel 101, thereby reducing the space occupied in the direction (vertical direction) of approaching or moving away from the floor panel 101. Therefore, it is possible to route the harness 2 even in a place where the gap in the direction (vertical direction) of approaching or moving away from the floor panel 101 is narrow.

In the harness routing structure 1 according to this embodiment, the harness 2 is routed by being bent back between the floor panel 101 and the sliding seat 200 (seat cushion 201) that constitute the vehicle body 100.
According to this harness routing structure 1, the harness 2 can be housed between the floor panel 101 and the sliding seat 200 (seat cushion 201). Therefore, the harness 2 is hidden from the view of a person seated on the sliding seat 200 or people around, thereby improving the aesthetic appearance.

In addition, the harness routing structure 1 according to this embodiment is provided with a protective cover portion 4 that covers the harness guide portion 3, and an opening hole 45h is formed in the protective cover portion 4 to allow the harness guide portion 3 (tip portion 32) to pass through.
According to this harness routing structure 1, the harness guide portion 3 can be protected by the protective cover portion 4. In addition, the harness guide portion 3 can be made invisible to a person seated on the sliding seat 200 and people around, thereby improving the aesthetic appearance.

In addition, the harness routing structure 1 of this embodiment is provided with a protective cap portion 5 that is fitted onto the harness guide portion 3 (tip portion 32), and the protective cap portion 5 is fitted into an opening hole 45h formed in the protective cover portion 4.
Such a harness routing structure 1 can prevent water, dust, or the tip of an umbrella from entering through the opening 45h of the protective cover 4. In addition, the inside of the protective cover 4 cannot be seen through the opening 45h, improving the aesthetic appearance.

For example, in the harness routing structure 1 disclosed herein, the main body insertion portion of the harness 2 is linear from the base end to the tip end of the main body 31. However, as shown in FIG. 11 , a helical portion 2S wound helically may be formed in part of the main body insertion portion of the harness 2. In other words, the harness passage 31P in the main body 31 may accommodate a helical portion 2S of the harness 2 wound helically.

With this harness routing structure 1, when the tip 32 rotates, the number of turns and the winding diameter of the spiral portion 2S at the main body insertion portion of the harness 2 increase or decrease. This configuration allows the spiral portion 2S at the main body insertion portion of the harness 2 to absorb twisting. This prevents the main body insertion portion of the harness 2 from twisting at a large torsion rate. Ultimately, even if the sliding seat 200 slides in the fore-and-aft direction, excessive loads can be prevented from acting on the main body insertion portion of the harness 2.

In addition, in the harness routing structure 1 disclosed herein, the harness guide portion 3 is attached to the floor panel 101 that constitutes the vehicle body 100 to guide the harness 2. However, as shown in FIG. 12 , the harness guide portion 3 may also be attached to the seat cushion 201 that constitutes the sliding seat 200 to guide the harness 2. In such a harness routing structure 1, the harness 2 may be routed by being bent back between the seat cushion 201 that constitutes the sliding seat 200 and the vehicle body 100 (floor panel 101).

With this harness routing structure 1, the harness 2 can be housed between the seat cushion 201 and the vehicle body 100 (floor panel 101). This makes it possible to hide the harness 2 from the person sitting in the sliding seat 200 or those around, improving the aesthetic appearance. Note that even if the harness guide 3 is attached to both the floor panel 101 and the seat cushion 201 to guide the harness 2, the same effect can be achieved if the harness 2 is routed by bending it back between the floor panel 101 and the seat cushion 201.

Furthermore, in the harness routing structure 1 disclosed herein, the protective cover 4 protects the harness guide 3 by covering it. Therefore, as shown in FIG. 13 , the protective cover 4 may house not only the harness guide 3 but also the air duct Da, and an outlet hole 4h for the air duct Da may be provided in the protective cover 4. In other words, in addition to the function of protecting the harness guide 3, the protective cover 4 may also house and protect the air duct Da and supply air sent through the air duct Da.

With this harness routing structure 1, the protective cover portion 4 not only protects the harness guide portion 3, but also houses and protects the air duct Da and supplies air sent through the air duct Da. This makes it possible to improve the aesthetic appearance by hiding the air duct Da from the view of the person sitting on the sliding seat 200 and those around them. Furthermore, temperature-controlled air spreads from the feet of the person sitting on the sliding seat 200 and those around them, improving the comfort of these people. At the same time, the air outlets 4h that produce the air blowing sound are located at the feet, improving the comfort of these people.

Finally, the harness routing structure 1 disclosed herein has been described as having a floor panel 101 as a component constituting the vehicle body 100, and a seat cushion 201 as a component constituting the sliding seat 200. However, the components constituting the vehicle body 100 may be other components such as a cross member or a chassis frame. The components constituting the sliding seat 200 may also be other components such as a cushion panel or a seat frame. Furthermore, the harness routing structure 1 disclosed herein has been described as having a corrugated tube 23 as the exterior component. However, the exterior component may also be other components such as a rubber tube or a vinyl tube.
