As shown in fig. 11, the rotating member 40 has a first member 42 and a second member 43. The first member 42 has a lead-out portion 42a and a half cylinder portion 42b. The lead-out portion 42a has a cylindrical shape. The half cylinder portion 42b is formed in a half cylinder shape having a semicircular-shaped concave portion 42 c. The axial direction of the lead-out portion 42a intersects, for example, orthogonally with, the axial direction of the recess 42 c. The inner space of the lead-out portion 42a and the recess 42c are connected to each other.
The second member 43 has a half cylinder portion 43a and a shaft portion 43b. The half cylinder portion 43a is formed in a half cylinder shape having a semicircular-shaped concave portion 43 e. The half cylindrical portion 43a is combined with the half cylindrical portion 42b of the first member 42 to form a cylindrical portion 48 (see fig. 9). The shaft portion 43b has a cylindrical shape, and protrudes from the half-cylinder portion 43 a. In a state where the first member 42 and the second member 43 have been combined, the shaft portion 43b and the lead-out portion 42a are coaxially positioned. The lead-out portion 42a and the shaft portion 43b protrude in opposite directions. A guide groove 43c is formed at the end of the shaft 43b. The guide groove 43c is a neck portion formed on the entire circumference of the shaft portion 43b. The turning mechanism 4A of the present embodiment can be disposed on rails 101 and 103 that guide the slide seat 10. In this case, the distal end portion 43d of the shaft portion 43b is inserted into the rails 101, 103 and guided by the rails 101, 103.
As shown in fig. 10, the support 41 includes a first support portion 44, a second support portion 45, and a side wall 46. The first support portion 44, the second support portion 45, and the side wall 46 are integrally formed. The side wall 46 has a generally rectangular flat plate shape. The first support portion 44 stands from one end of the side wall 46, and the second support portion 45 stands from the other end of the side wall 46. The first support portion 44 and the second support portion 45 are opposed to each other.
The first support portion 44 is provided with a bearing portion 44a for supporting the lead-out portion 42 a. The bearing portion 44a is a substantially U-shaped cutout. The second support portion 45 is provided with a bearing portion 45a for supporting the shaft portion 43b. The bearing portion 45a is a substantially U-shaped cutout. A pair of ribs 47, 47 are provided on the back surface 45b of the second support portion 45. The cross-sectional shape of the ribs 47, 47 is substantially T-shaped. When the rotation mechanism 4A is disposed on the rails 101 and 103, the distal end portions 47a of the ribs 47 are inserted into the rails 101 and 103 and guided by the rails 101 and 103.
The wire harness 2 pulled out from the winding device 3 is inserted into the rotating member 40 so that the distal end side of the wire harness 2 extends from the lead-out portion 42 a. For example, after the wire harness 2 is inserted into the lead-out portion 42a of the first member 42, the second member 43 is assembled to the first member 42. Thereby, the wire harness 2 is bent inside the rotating member 40, and the wire harness 2 is inserted into the passage 49 formed by the half tube portion 42b and the half tube portion 43 a. After the wire harness 2 is inserted into the rotating member 40, the rotating member 40 is assembled to the support 41.
As shown in fig. 9, the lead-out portion 42a of the rotating member 40 is rotatably supported by the bearing portion 44a. The shaft portion 43b of the rotating member 40 is rotatably supported by the bearing portion 45a. The turning mechanism 4A is mounted on the vehicle 100 such that the central axis AX of the lead portion 42a extends in the vehicle vertical direction H. The support 41 is fixed to the slide seat 10, and rotatably supports the rotating member 40. The tube 48 rotates relative to the support 41 about the central axis AX as a rotation center. The turning mechanism 4A is mounted on the vehicle 100 such that the protruding direction of the first support portion 44 and the second support portion 45 with respect to the side wall 46 is the vehicle width direction Y, for example.
Fig. 12 shows a wiring path of the wire harness 2 corresponding to the position of the adjustment portion 4. In fig. 12, the slide seat 10 is not shown. Fig. 12 shows a first position XF, a second position XM, and a third position XR of the turning mechanism 4A in the vehicle front-rear direction X. The first position XF is the position of the rotating mechanism 4A when the slide seat 10 is located at the front end position. The second position XM is the position of the rotating mechanism 4A when the slide seat 10 is located at the intermediate position. The third position XR is the position of the rotating mechanism 4A when the slide seat 10 is located at the rear end position.
As shown in fig. 12, when the turning mechanism 4A is located at the second position XM, the support 41 faces the tunnel portion 38 of the winding device 3 in the vehicle width direction Y. In this case, the posture of the tube portion 48 is such that the central axis AX2 of the tube portion 48 extends in the vehicle width direction Y. The wire harness 2 extends from the tube portion 48 in the vehicle width direction Y and linearly extends to the passage portion 38 of the winding device 3.
When the rotation mechanism 4A is located at the first position XF, the posture of the tube 48 is such that the central axis AX2 of the tube 48 extends toward the passage 38. That is, the end surface 48a of the tube portion 48 faces the channel portion 38. When the rotation mechanism 4A is located at the first position XF, the passage portion 38 is located obliquely rearward with respect to the tube portion 48. Therefore, the cylindrical portion 48 opens obliquely rearward. The wire harness 2 extends from the tube portion 48 toward the passage portion 38, and extends straight to the passage portion 38. The wire harness 2 is bent in the passage portion 38. More specifically, the wire harness 2 enters the interior of the winding device 3 while being bent along the third wall portion 37.
When the rotation mechanism 4A is located at the third position XR, the posture of the tube 48 is such that the central axis AX2 of the tube 48 extends toward the passage 38. That is, the end surface 48a of the tube portion 48 faces the channel portion 38. When the rotation mechanism 4A is located at the third position XR, the passage portion 38 is located obliquely forward with respect to the tube portion 48. Therefore, the cylindrical portion 48 opens obliquely forward. The wire harness 2 extends from the tube portion 48 toward the passage portion 38, and extends straight to the passage portion 38. The wire harness 2 enters the interior of the winding device 3 while being bent along the second wall portion 36.
As described above, the wiring structure 1 for a slide seat according to the present embodiment includes the rotation mechanism 4A. The rotation mechanism 4A can adjust the direction in which the wire harness 2 extends from the slide seat 10 to the direction from the tube portion 48 toward the winding device 3. Therefore, the rotating mechanism 4A can make the wire harness 2 follow the movement of the slide seat 10.
In addition, according to the wiring structure 1 for a slide seat according to the present embodiment, the degree of freedom in mounting the vehicle 100 is improved. For example, as a comparative example, a wiring structure in which the wire harness 2 is extended inside the rail 101 or inside the rail 103 was studied. In the wiring structure of the comparative example, the winding device 3 is disposed at the end portions of the rails 101, 103. Therefore, at least for the arrangement of the winding device 3, the degree of freedom is limited. In contrast, the wiring structure 1 for a slide seat according to the present embodiment has an improved degree of freedom in the arrangement of at least the winding device 3.
In addition, in the wiring structure of the comparative example, the overall length of the wire harness 2 is liable to become large. For example, when the distance from the front end position to the rear end position of the slide seat 10 is L1, the winding device 3 needs to pay out the wire harness 2 by the same length as the distance L1. In contrast, according to the wiring structure 1 for a slide seat according to the present embodiment, the maximum value of the length of the wire harness 2 paid out from the winding device 3 can be reduced. For example, by disposing the winding device 3 between the first position XF and the second position XM in the vehicle longitudinal direction X, the maximum value of the length of the payout harness 2 can be reduced.
As described above, the wiring structure 1 for a slide seat according to the present embodiment includes: a wire harness 2, a winding device 3, and an adjusting portion 4. The wire harness 2 connects the slide seat 10 that slides in the vehicle front-rear direction X and the vehicle body side. The winding device 3 is a device disposed on one of the slide seat 10 and the vehicle body side. The adjuster 4 is a device disposed on the other of the slide seat 10 and the vehicle body side.
The winding device 3 has a passage portion 38 through which the wire harness 2 is pulled out. The winding device 3 is configured to be capable of winding the wire harness 2 and paying out the wire harness 2. The shape of the tunnel portion 38 is a shape in which the width W1 of the vehicle front-rear direction X increases as it goes toward the outlet of the tunnel portion 38. The adjuster 4 has a tube 48 through which the wire harness 2 is inserted. The adjusting portion 4 is configured to adjust the extending direction of the wire harness 2 extending from the tube portion 48 to a direction toward the winding device 3. According to the wiring structure 1 for a slide seat according to the present embodiment, the degree of freedom in mounting the wiring structure 1 for a slide seat on the vehicle 100 is improved.
The adjustment unit 4 of the present embodiment is a rotation mechanism 4A including a cylindrical portion 48 and a support body 41 rotatably supporting the cylindrical portion 48. The adjustment unit 4 illustrated in the present embodiment is disposed in the slide seat 10. In this case, the support 41 is fixed to the slide seat 10. The rotation mechanism 4A can steplessly adjust the extending direction of the wire harness 2.
The slide seat 10 of the present embodiment includes a slider 7, and the slider 7 is slidably supported by a rail 101 disposed on the vehicle body side. The winding device 3 is disposed on the vehicle body side, and the support 41 is fixed to the slider 7.
Second embodiment
A second embodiment will be described with reference to fig. 13 to 16. In embodiment 2, the same reference numerals are given to the components having the same functions as those described in embodiment 1, and redundant description thereof is omitted. Fig. 13 is a plan view of a wiring structure for a slide seat according to the second embodiment, fig. 14 is a perspective view of the slide seat according to the second embodiment, fig. 15 is an exploded perspective view of an adjustment portion according to the second embodiment, and fig. 16 is a cross-sectional view of the wiring structure for a slide seat according to the second embodiment. Fig. 16 shows a section XVI-XVI of fig. 13. In the second embodiment, the point different from the first embodiment described above is, for example, the structure of the adjustment portion 4.
As shown in fig. 13 and 14, the adjustment portion 4 of the present embodiment is a tapered passage 4B provided in the tubular portion 12. The tube 12 is disposed on a side of the slide seat 10, for example, on a side of the armrest 73 opposite to the interior 5.
As shown in fig. 15, the tube 12 includes a main body 90 and a cover 91. The main body 90 and the cover 91 are formed of, for example, insulating synthetic resin. The main body 90 has: a bottom wall 92, a first side wall 93 and a second side wall 94. The bottom wall 92, the first side wall 93, and the second side wall 94 are integrally formed. The passage 4B of the wire harness 2 is formed by the bottom wall 92, the first side wall 93, and the second side wall 94. The bottom wall 92 is a wall portion that supports the wire harness 2 from below.
The first side wall 93 and the second side wall 94 stand up from the edge portion of the bottom wall 92, and face each other in the vehicle front-rear direction X. The first side wall 93 has a straight portion 93a and a curved portion 93b. The linear portion 93a extends linearly in the vehicle width direction Y. The base end 93c of the curved portion 93b is connected to the straight portion 93 a. The bent portion 93b is bent away from the second side wall 94 as going from the base end 93c toward the tip end 93d of the bent portion 93b.
The second side wall 94 has a straight portion 94a and a curved portion 94b. The linear portion 94a extends linearly in the vehicle width direction Y. The linear portion 94a is opposed to the linear portion 93a of the first side wall 93, and is parallel to the linear portion 93 a. The base end 94c of the curved portion 94b is connected to the straight portion 94a. The curved portion 94b is curved away from the first side wall 93 as going from the base end 94c toward the tip end 94d of the curved portion 94b.
Thus, the first side wall 93 and the second side wall 94 have a tapered shape in which the interval between the curved portions 93b and 94b increases toward the distal ends 93d and 94d of the curved portions 93b and 94b. That is, the width W2 of the passage 4B in the vehicle front-rear direction X is enlarged toward the opening 95. The tubular portion 12 is disposed in the slide seat 10 so that the opening 95 faces the interior 5 in the vehicle width direction Y. In this arrangement, the first side wall 93 is curved so as to face the vehicle front as it faces the tip 93d in the vehicle width direction Y. On the other hand, the second side wall 94 is curved so as to face the vehicle rear as it faces the tip end 94d in the vehicle width direction Y.
The cover 91 is engaged with the main body 90 to cover the passage 4B from above. The cover 91 has a cover portion 96 and an engaging portion 97. The cover 96 and the engaging portion 97 are integrally formed. The covering portion 96 is a portion covering the passage 4B from above. The cover portion 96 has a rectangular portion 96a and a tapered portion 96b. The rectangular portion 96a has a substantially rectangular shape in plan view. The rectangular portion 96a is formed so as to cover the linear portion 94a of the second side wall 94 from the linear portion 93a of the first side wall 93.
The shape of the tapered portion 96b in plan view is a tapered shape whose width becomes wider as it moves away from the rectangular portion 96a in the vehicle width direction Y. The tapered portion 96b is formed to cover from the curved portion 93b of the first side wall 93 to the curved portion 94b of the second side wall 94. The engagement portion 97 engages with the main body 90 to fix the cover 91 to the main body 90. The cover 91 has a holding portion 99 that holds the wire harness 2. The holding portion 99 protrudes from the cover portion 96 in the vehicle width direction Y. The wire harness 2 is fixed to the holding portion 99 by, for example, an adhesive tape or a tape member.
The body 90 and the cover 91 form the tube 12. The passage 4B of the tube 12 is formed by the curved portion 93B of the first side wall 93, the curved portion 94B of the second side wall 94, the bottom wall 92, and the covering portion 96. The passage 4B has a tapered shape, and is capable of adjusting the extending direction of the wire harness 2 from the tube portion 12. The tube 12 is disposed on the slide seat 10 so that the opening 95 faces the interior material 5. As shown in fig. 14, the barrel 12 may be configured such that the opening 95 protrudes from the side surface 10 a.
For example, as shown in fig. 13, in the case where the slide seat 10 is located at the front end position, the wire harness 2 extends in the direction from the tube portion 12 toward the winding device 3. The wire harness 2 is bent along the second side wall 94 of the tube portion 12, and extends obliquely rearward from the tube portion 12. As shown in fig. 13 and 16, the wire harness 2 extending from the tube portion 12 extends in the recess 62 of the protector 6 in the vehicle front-rear direction X. The passage 4B having a tapered shape can adjust the extending direction of the wire harness 2 and make the wire harness 2 follow the movement of the slide seat 10.
When the tube 12 is located further rearward than the winding device 3, the wire harness 2 extends obliquely forward from the passage 4B. In this case, the wire harness 2 is bent along the first side wall 93 of the tube portion 12 and extends in a direction from the tube portion 12 toward the winding device 3.
As described above, the adjustment portion 4 according to the second embodiment is the tapered passage 4B provided in the tubular portion 12. The wire harness 2 extends from the passage 4B toward the winding device 3 side. The width W2 of the passage 4B in the vehicle front-rear direction X becomes larger toward the winding device 3 side. The passage 4B allows the wire harness 2 to bend in the passage 4B, and enables the wire harness 2 to extend in a direction toward the winding device 3.
First modification of the embodiments
A first modification of the first and second embodiments will be described. Fig. 17 is a plan view of a wiring structure for a slide seat according to a first modification. The first modification differs from the first and second embodiments described above in that, for example, the adjustment portion 4 is disposed on a rail.
The adjustment unit 4 shown in fig. 17 is the rotation mechanism 4A described in the first embodiment. The rotation mechanism 4A is slidably supported by the rail 101. The support 41 of the rotation mechanism 4A is fixed to, for example, the slider 70 of the slide seat 10. That is, the rotation mechanism 4A moves integrally with the slide seat 10 in the vehicle front-rear direction X. The wire harness 2 pulled out from the lead-out portion 42a is routed along the slider 70, for example, and is connected to the equipment of the slide seat 10.
As shown in fig. 17, when the turning mechanism 4A moves in the vehicle front-rear direction X, the turning member 40 rotates relative to the support 41. The rotating member 40 rotates so that the wire harness 2 extends from the tube portion 48 in a direction toward the winding device 3.
In addition, the cylinder 12 of the second embodiment may be disposed on a rail instead of the rotating mechanism 4A. The adjustment unit 4 may be disposed on the rail 103. In this case, the adjustment portion 4 may be fixed to the slider 11 of the slide seat 10.
Second modification of the embodiments
A second modification of the first and second embodiments will be described. Fig. 18 is a front view of a wiring structure for a slide seat according to a second modification.

The wire harness 2 pulled out from the passage portion 38 of the winding device 3 is inserted into the tube portion 12. The wire harness 2 is fixed to the holding portion 99 of the tube portion 12, for example. The end of the wire harness 2 is connected to, for example, a power source and a control device of the vehicle 100.
The rotation mechanism 4A of the first embodiment may be used as the adjustment portion 4 instead of the passage 4B of the tube portion 12. In this case, the support 41 of the turning mechanism 4A is fixed to the vehicle body side.
The arrangement of the adjusting unit 4 and the winding device 3 is not limited to the arrangement illustrated in fig. 18. For example, the adjusting portion 4 and the winding device 3 may be disposed so as to face each other in the vehicle width direction Y. For example, the adjustment portion 4 may be fixed to the interior component 5. In this case, the winding device 3 may be disposed on the seat cushion 8 so that the channel portion 38 faces the interior material 5.
