JP 2004-25999 A

  By the way, in patent document 1, if the bending angle range of each link member in the first section is reduced, the cable guide may interfere with the peripheral portion. Further, simply increasing the bending angle range of each link member in the first section causes the cable in the cable guide to be bent with a small bending radius, so that the cable is disconnected due to repeated opening and closing of the sliding door. There is a fear.

  Therefore, the present invention aims to suppress the disconnection of the wire harness while suppressing the interference between the harness guide and its peripheral portion in the sliding door wiring device applied between the vehicle body and the sliding door. To do.

  In order to solve the above-mentioned problem, a first aspect is a slide disposed between a vehicle body and a slide door that is slid and moved on the side of the vehicle body while changing a distance to the vehicle body. A wiring device for a door, which is constituted by a wire harness that can be disposed between a vehicle body and a slide door, and a plurality of link members that are linearly connected, with one end supported on the vehicle body side. And a harness guide for guiding the wire harness between the vehicle body and the slide door in a state where the other end is supported on the slide door side, and the harness guide is provided on the slide door side. And a J-shaped bending section that can be bent and deformed in a J-shape while changing the bending portion as the sliding door is opened and closed. The J-shaped bending section includes a plurality of J-shaped bending sections. A first section in which the link member is rotatably connected within a range of a first allowable rotation angle, and a plurality of the link members are rotatable within a range of a second allowable rotation angle greater than the first allowable rotation angle. And connected second sections.

  A 2nd aspect is a wiring apparatus for sliding doors which concerns on a 1st aspect, Comprising: The said 2nd area is provided in the said sliding door side with respect to the said 1st area.

  A 3rd aspect is a wiring apparatus for sliding doors which concerns on a 2nd aspect, Comprising: The said 2nd area is provided in the range of the extent which draws a 1/2 arc on the said sliding door side.

  According to the first aspect, the minimum bending radius of the J-shaped bending section can be changed between the case of bending in the first section and the case of bending in the second section. As a result, the bending state of the J-shaped bending section can be regulated with an appropriate bending radius according to the distance of the sliding door with respect to the vehicle body, and the interference between the harness guide and its peripheral portion can be suppressed. Moreover, the bending radius of a harness guide and a wire harness can be enlarged in the state in which a harness guide bends in a 1st area. Thereby, disconnection of a wire harness can be suppressed.

  According to the second aspect, the harness guide is bent in the first section when the slide door is opened while drawing a path approaching the vehicle body after the slide door is moved away from the vehicle body. Thus, the bending radius of the harness guide and the wire harness can be increased. Assuming that the sliding door may be opened and closed between a closed state and a partially opened state, increasing the bending radius of the wire harness in this state enables effective disconnection of the wire harness. Can be suppressed. On the other hand, as the slide door opens, the harness guide bends in the second section, and the bending radius of the harness guide and the wire harness can be reduced. Thereby, interference with a harness guide and its peripheral part can be suppressed.

  According to the third aspect, the bending radius of the harness guide and the wire harness can be increased as much as possible in a state before the sliding door is opened and the second section draws a half arc. Disconnection can be effectively suppressed.

In FIG. 1, the movement path of the sliding door 14 when the sliding door 14 is opened and closed is indicated by an arrow A, and the state change of the sliding door wiring device accompanying the opening and closing of the sliding door 14 is indicated by a dotted line.

<Relationship between body and sliding door>
For convenience of explanation, the relationship between the vehicle body 10 and the slide door 14 will be described.

  The automobile includes a vehicle body 10 and a slide door 14 provided on one side of the vehicle body 10. A boarding port 11 through which a person can get on and off is provided on one side of the vehicle body 10. The slide door 14 is a position (closed position P1) where the entrance 11 is closed by a slide support mechanism including a guide rail 12 and a movable support that supports the slide door 14 in a state of being movable along the guide rail 12. ) And a position (open position P2) at which the entrance 11 is opened.

  The slide door 14 is configured to be able to open and close the entrance 11 by sliding and moving on the side of the vehicle body 10 while changing the distance to the vehicle body 10. Here, the slide door 14 gradually increases the distance to the vehicle body 10 from the closed position P1 to the middle position where it slides from the closed position P1 to the open position P2, and the vehicle body until it moves from the middle position to the open position P2. Slide and move so as to gradually reduce the distance to the main body 10 (see arrow A).

  The sliding door wiring device 20 is disposed between the vehicle body 10 and the sliding door 14 as described above.

  The harness guide 24 is covered with a protective member 60. The protection member 60 is formed into a bendable cylindrical shape by an elastic material such as rubber or elastic plastic.

<Overall configuration of wiring device for sliding door>
The overall configuration of the sliding door wiring device 20 will be described. 2 to 5 are schematic plan views showing the sliding door wiring device 20. FIG. 2 shows the sliding door wiring device 20 in a state where the sliding door 14 is in the closed position P1, and FIG. 3 shows the sliding door 14 in the middle from the closed position P1 to the open position P2. 4 shows the sliding door wiring device 20 in a state farthest from the vehicle body 10 (see the position Pm1 of the sliding door side support member 50 in FIG. 1). FIG. 4 shows the sliding door 14 in FIG. FIG. 5 shows the sliding door wiring device 20 in a state in the middle of the position shown in FIG. 1 from the position shown in FIG. 1 (see the position Pm2 of the sliding door side support member 50 in FIG. 1). The wiring apparatus 20 for sliding doors in the state in the position P2 is shown.

  As shown in FIGS. 1 to 5, the sliding door wiring device 20 includes a wire harness 22 and a harness guide 24.

  The wire harness 22 includes at least one electric wire 23 (see FIGS. 6 and 7) for supplying power to or transmitting signals to an electrical component provided on the slide door 14. Here, the wire harness 22 has a configuration in which a plurality of electric wires 23 are bundled. The wire harness 22 extends outward at both ends of the harness guide 24 and is electrically connected to the various electrical components in the slide door 14 or the vehicle body 10 through a connector and other wire harnesses. The wire harness 22 may be branched into a plurality of portions extending outward from both ends of the harness guide 24.

  The wire harness 22 is disposed between the vehicle body 10 and the slide door 14 in a state where the wire harness 22 is inserted into the harness guide 24, and electrically connects the electric component on the vehicle body 10 side and the electric component on the slide door 14 side. It plays a role of connection.

  The harness guide 24 is configured by connecting a plurality of link members 30 linearly. The wire harness 22 is supported by the harness guide 24 so as to be guided by continuously passing through the plurality of link members 30. Then, with one end portion of the harness guide 24 supported on the vehicle body main body 10 side and the other end portion of the harness guide 24 supported on the slide door 14 side, the vehicle body main body is moved according to the opening / closing movement of the slide door 14. The wire harness 22 is guided between 10 and the sliding door 14.

  More specifically, the plurality of link members 30 are connected in a straight line, and are connected so as to be rotatable around one axis between adjacent ones. Thereby, the harness guide 24 can be bent and deformed mainly within one plane. Here, the harness guide 24 guides the wire harness 22 so that the wire harness 22 bends in a horizontal plane orthogonal to the vertical direction. Thereby, the hanging of the wire harness 22 is suppressed, and in particular, interference with the peripheral members below the sliding door wiring device 20 is suppressed.

  Moreover, the some link member 30 is connected so that rotation within the range of the controlled rotation angle is possible. As a result, the bending degree of the harness guide 24 accompanying the opening and closing movement of the slide door 14 is restricted, interference with peripheral members around the horizontal direction of the slide door wiring device 20 is suppressed, and the wire harness 22 is extremely It is formed not to bend too much. This point will be further described later.

  The harness guide 24 is supported with respect to the vehicle body 10 and the slide door 14 by the following configuration.

  That is, the vehicle body main body side support member 40 is connected to one end of the harness guide 24. The vehicle body main body side support member 40 is a member formed of resin or the like, and includes a cylindrical portion 42 through which the wire harness 22 can be inserted. One end portion of the harness guide 24 is connected to the cylindrical portion 42 in the cylindrical portion 42. As a connection structure between the one end portion of the harness guide 24 and the cylindrical portion 42, for example, a rotatable connection structure similar to a connection structure between link members 30 described later can be employed. But the one end part of the harness guide 24 may be connected with the vehicle body main body side supporting member in the non-rotatable state.

  One end portion of the wire harness 22 led out from one end portion of the harness guide 24 is guided to the vehicle body main body 10 side through the tubular portion 42 and is electrically connected to an electric component on the vehicle body main body 10 side.

  The vehicle body side support member 40 is fixed to the vehicle body 10. Here, the vehicle body main body side support member 40 includes a fixed piece 44 extending to the side of the cylindrical portion 42, and the fixed piece 44 is fixed to the vehicle body main body 10 by screwing or the like. Fixed to. Thereby, the harness guide 24 is supported with respect to the vehicle body 10 via the vehicle body side support member 40.

  A sliding door side support member 50 is connected to the other end of the harness guide 24.

  The slide door side support member 50 is a member formed of resin or the like, and is fixed to the slide door 14 at a fixed position by screwing the slide door 14 or the like.

  The slide door side support member 50 includes an end link member 54 and a support main body 52 that rotatably supports the end link member 54. The end link member 54 is connected to the support main body 52 so as to be rotatable between a direction toward the rear of the vehicle body 10 and a direction toward the side toward the vehicle body 10. Here, the allowable rotation angle of the end link member 54 is 90 degrees, but it may be an angle larger or smaller than 90 degrees, and the end link member 54 itself is relative to the support main body 52. And may have a fixed posture.

  As a connection structure between the other end of the harness guide 24 and the end link member 54, for example, a rotatable connection structure similar to a connection structure between link members 30 described later can be employed. But the other end part of the harness guide 24 may be connected with the slide door side support member 50 in the non-rotatable state.

  One end portion of the wire harness 22 led out from the other end portion of the harness guide 24 is guided to the slide door 14 side through the end link member 54 and the support main body portion 52, and is electrically connected to the electrical components on the slide door 14 side. Connected to.

  The slide door side support member 50 is fixed at a fixed position with respect to the slide door 14, whereby the harness guide 24 is supported with respect to the vehicle body main body 10 via the slide door side support member 50.

  For this reason, as the sliding door 14 is opened and closed, the other end of the harness guide 24 is relatively moved along the moving path A of the sliding door 14 so that the other end of the harness guide 24 passes by one side of the harness guide 24. Will move.

<Bending restriction mode of harness guide>
A bending restriction mode in each part in the extending direction of the harness guide 24 will be described.

  The harness guide 24 includes a swing bending section R1 and a J-shaped bending section R2.

  The swing bending section R <b> 1 is provided on the side of the vehicle body 10 in the harness guide 24. The swing bending section R1 is a section configured to bend so as to swing the head to both sides of the vehicle body main body side support member 40 (front and rear direction of the vehicle body 10) in a horizontal plane. In the main swing bending section R1, the allowable rotation angle of the connecting portion of each link member 30 is set in a range in which the harness guide 24 hardly interferes with the member on the vehicle body 10 side.

  Here, the swing bending section R1 includes a section R1a in which a plurality of link members 30 are connected so as to be rotatable in only one direction from a straight state, and a plurality of link members 30 are connected in a bidirectional manner from the straight state. Section R1b.

  The section R1a is set on the vehicle body 10 side of the swing bending section R1, and here is a section including a plurality (here, three) of connecting portions of the link members 30 (FIGS. 2 to 5). reference).

  The section R1b is set on the J-shaped bending section R2 side (sliding door 14 side) in the swing bending section R1, and here, a plurality of (here, six) connecting portions of the link members 30 are combined. (Refer to FIGS. 2 to 5).

  When the slide door 14 is in the closed position P1 and the other end of the harness guide 24 is pulled to the right (rear) in FIG. 2, the swing bending section R1 draws a curve (gradual curve). The state is directed to the right in FIG. 2, that is, toward the front of the vehicle body 10. In this case, the allowable rotation angle of the connecting portion of the link members 30 in the swing bending section R1 is set in a range in which interference between the harness guide 24, the slide door 14, and the vehicle body 10 can be suppressed.

  On the other hand, when the slide door 14 is in the open position P2 and the other end of the harness guide 24 is pulled to the left (front) in FIG. 5, the section R1a in the swing bending section R1 is in a straight line state. R1b draws a curve and turns to the left in FIG. 5, that is, toward the rear of the vehicle body 10. In this case, the allowable rotation angle of the connecting portion between the link members 30 in the swing bending section R1 is within a range in which interference between the harness guide 24 and the rear frame portion of the entrance 11 of the vehicle body 10 can be suppressed. Is set.

  In the middle of the movement of the slide door 14 from the closed position P1 to the open position P2, the swing bending section R1 is bent and deformed from the state shown in FIG. 2 to the state shown in FIG. Here, at the initial stage when the slide door 14 moves from the closed position P1 to the open position P2, the swing bending section R1 is bent and deformed from the state shown in FIG. 2 to the state shown in FIGS.

  As a specific example, the connecting portion of the link members 30 in the section R1a is configured to be able to rotate 30 degrees to the rear of the vehicle body 10 and to rotate 0 degrees to the front of the vehicle body 10, and its allowable rotation angle is A total range of 30 degrees is set. In addition, the connecting portion of the link members 30 in the section R1b is configured to be able to rotate 30 degrees toward the rear of the vehicle body 10 and 15 degrees toward the front, and its allowable rotation angle is in a range of 45 degrees in total. Is set.

  For this reason, in the state where the slide door 14 is in the closed position P1, the swing bending section R1 can be extended while drawing a curve from the vehicle body main body side support member 40 toward the front of the vehicle in the entrance 11.

  Further, in a state where the slide door 14 is in the open position P2, the section R1 extends linearly and guides the wire harness 22 so as to face outward from the vehicle body 10. Further, the section R2 extends toward the rear of the vehicle body 10 while drawing a curve. At this time, since the connecting portions of the link members 30 in the section R2 are bent by 15 degrees, assuming that six connecting portions are provided as in the above example, the section R2 has a 1/4 arc. It will be in a state bent to draw. For this reason, in this state, the swing bending section R1 can guide the wire harness 22 outward from the vehicle body 10 in the section R1a and then turn toward the rear of the vehicle while gently bending in the section R1b. .

  The J-shaped bending section R2 is provided on the slide door 14 side of the harness guide 24. This J-shaped bending section R2 is configured to be able to be bent and deformed into a J-shape while changing the bending portion as the slide door 14 is opened and closed.

  That is, the J-shaped bending section R2 is configured to be bent only in one direction from a straight state in a horizontal plane. Here, the J-shaped bending section R2 includes one connection portion between the end link member 54 and the link member 30, and a plurality (14 in this case) of connection portions between the link members 30. Then, the bending state of the J-shaped bending section R2 is restricted by restricting the rotation of these connecting portions so that they can rotate only in one direction from the linear state.

  When the sliding door 14 is in the closed position P1, the other end of the harness guide 24 is pulled to the right (front) in FIG. 2, and the J-shaped bending section R2 is on the sliding door 14 side of the swing bending section R1. And the sliding door side support member 50 extend linearly (see FIG. 2). Further, when the slide door 14 is moved from the closed position P1 toward the open position P2, the other end of the harness guide 24 is gradually pulled to the left (rear) in FIGS. The J-shaped bending section R2 is bent and deformed into a J-shape including a bent portion that protrudes toward the rear of the vehicle. At this time, the bending portion of the J-shaped bending section R2 varies depending on the position of the slide door 14. More specifically, as the slide door 14 moves from the closed position P1 to the open position P2, the bent portion in the J-shaped bending section R2 changes from the vehicle body 10 side to the slide door 14 side. Thereby, the sliding door 14 can be opened while suppressing interference between the harness guides 24 (wire harness 22) and interference between the harness guide 24 and its peripheral members.

  The J-shaped bending section R2 includes a first section R2a in which a plurality of link members 30 are rotatably connected within a range of a first allowable rotation angle, and the plurality of link members 30 are larger than the first allowable rotation angle. And a second section R2b that is rotatably connected within the range of the first allowable rotation angle. Here, the second section R2b also includes a connection portion between the link member 30 and the slide door side support member 50, but it is not essential to include this connection portion. The link member 30 at the end of the harness guide 24 on the slide door side support member 50 side may be connected to the slide door side support member 50 in a fixed posture.

  In the present embodiment, the second section R2b is provided on the slide door 14 side with respect to the first section R2a.

  In the first section R2a, the first allowable rotation angle of the connecting portion is relatively small. Therefore, the first section R2a can be bent with a relatively large bending radius. On the other hand, in 1st area R2b, the 2nd allowable rotation angle of a connection part is larger than a 1st allowable rotation angle. For this reason, the second section R2b can be bent with a bending radius smaller than that of the first section R2a.

  For this reason, when the bending portion of the J-shaped bending section R2 is in the first section R2a while the slide door 14 moves from the closed position P1 to the open position P2, the wire harness 22 has a relatively large bending radius. Guided to turn. When the sliding door 14 approaches the open position P2 and the bending portion of the J-shaped bending section R2 is positioned in the first section R2b, the wire harness 22 is guided to be bent with a relatively small bending radius. .

  As a specific example, the connecting portion in the first section R1a can be rotated by 30 degrees from one side to the other side, and cannot rotate to the other side (that is, can rotate by 0 degrees). The corners are set to a total range of 30 degrees. In addition, the connecting portion in the second section R2b is configured to be able to rotate 40 degrees from one side to the other side, and not to rotate forward to the other side (that is, to be able to rotate 0 degrees). A range of 40 degrees is set. In this case, the minimum bending radius in the second section R2b can be made about 30% smaller than the minimum bending radius in the first section R2a.

  Note that the allowable rotation angle of the connecting portion between the link members 30 in the swing bending section R1 and the J-shaped bending section R2 depends on the number of link members 30, the arrangement position of the vehicle body 10 and the slide door 14, the shape, and the like. It is changed appropriately.

<Example of link member>
An example of a configuration for restricting the allowable rotation angle of the connecting portion between the link members 30 will be described. In the following description, the link member 30 will be described in three types. The first type is a configuration example in which a plurality of link members 30 (A) are coupled so as to be rotatable only in one direction from a straight state. The second type is a configuration example in which a plurality of link members 30 (B) are coupled so as to be rotatable in both directions from a straight state. The third type is a configuration example in which a plurality of link members 30 (C) are connected so as to be rotatable only in one direction from a straight state, and is an example in which the allowable rotation angle is larger than that of the first type. .

  As shown in FIGS. 6 to 8, the link member 30 (A) is a member formed of resin or the like, and includes a pair of side pieces 32 and a connection support piece 38 that supports the pair of side pieces 32. .

  The side piece 32 is formed in an elongated flat plate shape, and a connection hole 33 is formed at one end thereof, and a connection projection 34 is provided at the other end. The connecting hole 33 is formed in a circular hole. Further, the connecting protrusion 34 is formed in a circular protrusion shape protruding outward from the outer surface of the side piece 32, and is configured to be fitted in the connecting hole 33 in a rotatable state. Here, the connecting protrusion 34 has a partial inclined surface that gradually decreases its height dimension toward the other end of the side piece 32, and the connecting protrusion 34 is connected to the connecting hole 33. It can be inserted smoothly.

  Moreover, the connection support piece 38 is comprised so that a pair of side piece 32 may be supported in the parallel state which provided the space | interval between them. Here, the connection support pieces 38 are substantially flat members, and a pair of connection support pieces 38 are provided so as to connect and support the outer edges of the pair of side pieces 32.

  In a state where the pair of side pieces 32 are connected and supported by the connection support piece 38, the pair of connection protrusions 34 of the pair of side pieces 32 are coaxially arranged, and the pair of connection holes 33 are coaxially arranged. It is arranged.

  Moreover, in each link member 30, the square space enclosed by a pair of side piece 32 and a pair of connection support piece 38 is formed, and the wire harness 22 is penetrated in the space.

  In addition, the outer surface interval of the peripheral portion of the connection protrusion 34 in the pair of side pieces 32 is formed to be the same as the inner surface interval of the peripheral portion of the connection hole 33 in the pair of side pieces 32. And the connection hole 33 was formed in the part in which the connection protrusion 34 was formed among the pair of side pieces 32 of the link member 30 (A) and the pair of side pieces 32 of the other link member 30 (A). The plurality of link members 30 (A) are arranged between the connection protrusions 34 and the connection holes 33 by disposing each of the pair of connection protrusions 34 in the pair of connection holes 33. It is connected to be rotatable around an axis.

  Moreover, the one end part of a pair of side piece 32 is formed in the arc-shaped shape which rounded the corner.

  Further, at the other end of the pair of side pieces 32, a restriction piece 35 that restricts the rotation angle is formed. That is, the restriction piece 35 is disposed between the pair of connection support pieces 38 in a state where the plurality of link members 30 (A) are connected. When the plurality of link members 30 (A) rotate, the rotation angle is regulated by the restriction piece 35 coming into contact with one of the pair of connection support pieces 38.

  In the example shown in FIGS. 6 to 8, one side edge 35 (A) a (the lower side edge in FIGS. 6 and 8) of the regulating piece 35 extends along the extending direction of the side piece 32. It extends. For this reason, in the state which connected several link member 30 (A), one link member 30 (A) is one side (for example, link member 30 of the left side of FIG. 8 with respect to the other link member 30 (A). When (A) tries to rotate to the upper side with respect to the right link member 30 (A), the side edge 35 (A) a becomes a corresponding connection support piece 38 (here, the lower connection support piece 38). Abut. Thereby, one link member 30 (A) is regulated so as not to rotate to one side with respect to the other link member 30 (A).

  In the example shown in FIGS. 6 to 8, the other side edge 35 (A) b (the upper side edge in FIGS. 6 and 8) of the regulating piece 35 is on the outer side in the extending direction of the side piece 32. It is inclined inward. Here, the side edge 35 (A) b is inclined at an angle α with respect to the extending direction of the side piece 32. For this reason, in the state which connected several link member 30 (A), one link member 30 (A) is the other side (for example, link member 30 of the left side of FIG. 8 with respect to the other link member 30 (A). When (A) rotates to the lower side relative to the right link member 30 (A) and rotates by an angle α, the side edge 35 (A) b corresponds to the corresponding connection support piece 38 (here, the upper connection support piece). 38). Thereby, one link member 30 (A) is restricted so that it can rotate within the range of α degrees to the other side with respect to the other link member 30 (A).

  As a result, the plurality of link members 30 (A) are regulated so as to be rotatable by a permissible rotation angle α in one direction from the linear state.

  The second type of link member 30 (B) shown in FIG. 9 is different from the first type of link member 30 (A) in the shape of the regulation piece 35 (B) corresponding to the regulation piece 35. is there.

  That is, in this example, one side edge 35 (B) a (lower side edge in FIG. 9) of the regulation piece 35 (B) is inclined inward toward the outside in the extending direction of the side piece 32. doing. Here, the side edge 35 (B) a is inclined at an angle β1 with respect to the extending direction of the side piece 32. Further, the other side edge 35 (B) b (the upper side edge in FIG. 9) of the regulating piece 35 (B) is inclined inward toward the outside in the extending direction of the side piece 32. Here, the side edge 35 (B) b is inclined at an angle β2 with respect to the extending direction of the side piece 32.

  Therefore, in the same manner as described above, one link member 30 (B) is connected to the other link member 30 (B) on one side (for example, in FIG. When the left link member 30 (B) rotates upward (upward with respect to the right link member 30 (B)) and rotates by an angle β1, the side edge 35 (B) a corresponds to the corresponding connecting support piece 38 (here, the lower Side connection support piece 38). Thereby, one link member 30 (B) is regulated so that it can rotate within the range of β1 degree to the other side with respect to the other link member 30 (B).

  Also, one link member 30 (B) is on the other side relative to the other link member 30 (B) (for example, the left link member 30 (B) in FIG. 9 is against the right link member 30 (B)). When the angle is rotated by the angle β2, the side edge 35 (B) b comes into contact with the corresponding connection support piece 38 (here, the upper connection support piece 38). Thereby, one link member 30 (B) is regulated so that it can rotate within the range of β2 degrees to the other side with respect to the other link member 30 (B). Thereby, one link member 30 (B) is regulated so as to be capable of rotating in both directions within a range of (β1 + β2) degrees with respect to the other link member 30 (B).

  The third type of link member 30 (C) shown in FIG. 10 is different from the first type of link member 30 (A) in the shape of the restriction piece 35 (C) corresponding to the restriction piece 35. is there.

  That is, in this example, one side edge 35 (C) a (lower side edge in FIG. 10) of the restriction piece 35 (C) extends along the extending direction of the side piece 32. Yes. Further, the other side edge 35 (C) b (the upper side edge in FIG. 10) of the regulation piece 35 (C) is inclined inward toward the outside in the extending direction of the side piece 32. Here, the side edge 35 (C) b is inclined at an angle γ with respect to the extending direction of the side piece 32. Note that the angle γ is larger than the angle α.

  Therefore, in the same manner as described above, one link member 30 (C) is connected to the other link member 30 (C) on one side (for example, in FIG. When the left link member 30 (C) is about to rotate upward (to the right link member 30 (C)), the side support 35 (C) a corresponds to the corresponding connection support piece 38 (here, the lower connection). It abuts on the support piece 38). Thereby, one link member 30 (C) is regulated so as not to rotate to one side with respect to the other link member 30 (C). Also, one link member 30 (C) is on the other side relative to the other link member 30 (C) (for example, the left link member 30 (C) in FIG. 10 is on the right link member 30 (C)). When it rotates to the lower side and rotates by the angle γ, the side edge 35 (C) b comes into contact with the corresponding connecting support piece 38 (here, the upper connecting support piece 38). Thereby, one link member 30 (C) is regulated so that it can rotate within the range of γ degrees on the other side with respect to the other link member 30 (C). As a result, one link member 30 (C) is regulated so as to be rotatable with respect to the other link member 30 (C) by a permissible rotation angle γ in one direction from the linear state.

  For example, the first type link member 30 (A) is applied to the section R1a and the section R2a, the second type link member 30 (B) is applied to the section R1b, and the third type link member 30 (A) is applied to the section R1b. The link member 30 (C) is applied to the section R2b.

<Operation of Wiring Device 20 for Sliding Door>
The operation of the sliding door wiring device 20 will be described with reference to FIGS.

  First, when the slide door 14 is closed, the swing bending section R1 is bent so as to face the front while drawing a curve, and the J-shaped bending section R2 is linearly extended (FIG. 1). And FIG. 2).

  When the sliding door 14 is opened halfway from this state, the swing bending section R1 is bent so as to face backward while drawing a curve, and the curve is drawn so that the J-shaped bending section R2 protrudes backward. Then, it is bent and deformed into a J-shape (see FIG. 3). In a state where the slide door 14 is moved from the closed position P1 to the open position P2, the bending portion of the J-shaped bending section R2 exists in the first section R2a. For this reason, the bending radius of the J-shaped bending section R2 in this state is relatively large.

  In this state, since the slide door 14 is relatively far away from the vehicle body 10, there is no problem even if the bending radius of the J-shaped bending section R2 is large.

  When the sliding door 14 is further opened, the bent portion of the J-shaped bending section R2 moves to the second section R2b side (see FIG. 4). In this state, the bending portion of the J-shaped bending section R2 is in a state of drawing a 1/2 arc by the entire area of the second section R2b. In other words, the second section R2b is provided in a range where a half arc can be drawn in the portion of the harness guide 24 on the slide door 14 side.

  At this time, the slide door 14 gradually approaches the vehicle body 10, but the bend radius of the bent portion formed by the second section R2b is relatively small, so that the harness guide 24 interferes with the slide door 14 and the like. Is suppressed.

  When the sliding door 14 is fully opened, the first section R2a of the J-shaped bending section R2 extends linearly, and the second section R2b supports the body body side while drawing a curve from the sliding door side support member 50. It will be in the state bent so that it may extend toward the member 40. FIG.

  When the slide door 14 is closed, the slide door 14 is bent and deformed in the reverse manner.

<Effects>
According to the sliding door wiring device 20 configured as described above, the J-shaped bending section R2 changes the minimum bending radius depending on whether it is bent in the first section R2a or in the second section R2b. be able to. Accordingly, the bending state of the J-shaped bending section R2 is regulated with an appropriate bending radius according to the distance of the slide door 14 with respect to the vehicle body 10 and thereby the interference between the harness guide 24 and its peripheral portion is suppressed. Can do.

  Further, the bending radius of the harness guide 24 and the wire harness 22 can be increased in a state where the harness guide 24 is bent in the first section R2a. Thereby, disconnection of the wire harness 22 can be suppressed.

  In particular, when the sliding door 14 is opened by drawing a moving path A that approaches the vehicle body 10 after moving away from the vehicle body 10, the second section R2b is in the middle of the opening of the sliding door 14 with respect to the first section R2a. The configuration is provided on the slide door 14 side. For this reason, it is possible to increase the bending radii of the harness guide 24 and the wire harness 22 while the harness guide 24 is bent in the first section R2a when the slide door 14 is being opened. In general, assuming that the sliding door 14 is opened and closed between a closed state and a partially opened state, and may not be completely opened, the sliding door 14 may be opened halfway. By increasing the bending radii of the harness guide 24 and the wire harness 22 at the stage, it becomes possible to effectively suppress the disconnection of the wire harness 22.

  On the other hand, when the slide door 14 is fully opened, the harness guide 24 bends in the second section R2b, and the bending radii of the harness guide 24 and the wire harness 22 can be reduced. Thereby, in the state which the slide door 14 opened completely and was approaching the vehicle body main body 10 side, interference with the harness guide 24 and its peripheral part can be suppressed.

  But the example of a setting of 1st area R2a and 2nd area R2b is not restricted to the said example. For example, when drawing a moving path that gradually moves away from the vehicle body as the slide door opens, the first section may be provided on the slide door side with respect to the second section. That is, in the J-shaped bending section, the first section and the second section need only be provided in a mixed manner.

  Further, the second section R2b is a portion of the harness guide 24 on the slide door 14 side and is provided in a range where a half arc can be drawn. Therefore, when the slide door 14 is opened, the second section R2b is provided. The bending radius of the harness guide 24 and the wire harness 22 can be increased as much as possible in a state before R2b draws a half arc, and disconnection of the wire harness 22 can be effectively suppressed. However, the second section R2b may be provided in a wider range or a narrower range.

  As described above, the present invention has been described in detail. However, the above description is illustrative in all aspects, and the present invention is not limited thereto. It is understood that countless variations that are not illustrated can be envisaged without departing from the scope of the present invention.
