< wire harness routing Structure 21>
In fig. 1, a harness routing structure 21 is used as a structure relating to routing of a harness 22 routed to a seat (seat) of an automobile, for example. The seat is an example, and is not particularly limited as long as it is related to the fixed structure 23 and the movable structure 24 that can reciprocate in a predetermined direction (the direction of arrow P) with respect to the fixed structure 23. In the present embodiment, the fixed structure 23 corresponds to a floor of an automobile and a base portion for a seat fixed to the floor, and the movable structure 24 corresponds to a seat (seat). The two-dot chain line indicating the moving structure 24 indicates a "seated portion" that slides in the arrow P direction, whereby the driver and the rider can optimally secure the space under the feet. Fig. 1(a) shows a state of a first position in which the "seating portion" is drawn forward (drawn in the vehicle traveling direction), and fig. 1(b) shows a state of a second position in which the "seating portion" is drawn rearward. Note that an arrow Q orthogonal to the arrow P in fig. 1 indicates the vertical direction. The fixed structure 23 is disposed below the moving structure 24 in the direction of arrow Q.
The harness 22 is configured to include: a trunk line 25; a branch line 26 branched from the trunk line 25; an electrical connection member and an electrical junction box, not shown, provided at the end of the trunk line 25; a plurality of clamps 27 for holding the trunk 25 to the fixed structure 23; and a protector 28 for holding the branch wire 26 to the moving structure 24. The protector 28 constituting the wire harness 22 is a characteristic member in the wire harness routing structure 21, and has an effect of enabling smooth movement of a wire harness main body 29, which will be described later, of the branch wire 26, and also has an effect of preventing interference with the wire harness main body 29.
According to the harness routing structure 21, since the protector 28 has this feature, the harness main body 29 described later can be moved as shown in fig. 2 and 3 by reciprocating the moving structure 24 in the arrow P direction. Specifically, referring to fig. 4 and 5 in which the observation direction is changed, the curvature of the curved portion 31 of the wire harness intermediate portion 30 in the wire harness main body 29 can be moved with little change. Therefore, the harness main body 29 can be smoothly moved as described above. According to the harness routing structure 21, since the curvature can be moved substantially without change, the bending does not become severe as in the conventional art, and as a result, the effect of preventing the interference between the harness main body 29 and the protector 28 is achieved.
The above-described structure of the wire harness 22 will be explained below. The harness main body 29 and the protector 28 constituting the harness routing structure 21 will also be described.
< trunk line 25 and branch line 26 of wire harness 22 >
In fig. 4 and 5, the trunk 25 is configured to include a thick wire bundle formed by bundling a large number of wires and a thick corrugated tube (as an example) for accommodating the wire bundle. The trunk lines 25 are wired in a state where a predetermined path is maintained by providing clamps 27 at a plurality of positions. The branch line 26 includes: a harness main body 29, one end of which branches from the trunk line 25; and a connector 32 provided at the other end (tip) of the branch line 26. In other words, the wire harness body 29 can be said to be a branch wire body. The wire harness body 29, which is a body of the branch wire 26, is configured to include a plurality of electric wires 33 and a thin corrugated tube 34 that houses the electric wires 33. The wire 33 is a low-voltage wire and includes a conductor and an insulator. The illustrated electric wire 33 is formed in a state where two electric wires are wound with a tape, for example, on the distal end side of the harness body 29. As is apparent from the above description, the harness main body 29 has a bendable structure that is wired across the fixed structure 23 and the movable structure 24 (see fig. 1). The reference numeral 30 in the harness main body 29 denotes the harness intermediate portion as described above. In addition, reference numeral 31 denotes a bent portion. The bellows 34 is provided at a portion from the branch portion of the trunk line 25 to the protector 28.
< relative protector 28 >
In fig. 6 and 7, the protector 28 is a characteristic member of the wire harness routing structure 21, and is fixed to the moving structure 24 (see fig. 1). The protector 28 is a resin molded product, and is formed to be able to accommodate and protect a part of the harness main body 29 as shown in the drawing. The protector 28 has an elongated box-shaped protector body 35 and a harness guide 36 continuous with the protector body 35, and is formed in the shape shown in the drawing. As a characteristic function of the protector 28, the arrangement of the harness main body 29 in the harness guide 36 changes as shown in fig. 6 to 9 depending on the position of the movable structure 24 with respect to the fixed structure 23 (see fig. 1). In addition, as a characteristic function, even if the arrangement of the wire harness main body 29 in the harness guide 36 is changed, the wire harness main body 29 moves in a state in which the curvature of the curved portion 31 of the wire harness intermediate portion 30 is almost unchanged.
< about the protector main body 35 >
In fig. 6, 7, and 10, the protector main body 35 is formed in an elongated box shape. The protector body 35 has a housing portion 37 and a cover 38. The housing portion 27 and the cover 38 are continuously formed via a hinge 39. The housing portion 27 and the lid 38 are locked by the lock portion 40. The protector main body 35 has a leading portion 41 on one end side and a leading portion 42 on the other end side formed at one end and the other end in the longitudinal direction. The harness guide 36 is formed continuously with the lead-out portion 41 on one end side. The tape winding portion 43 is formed continuously with the lead-out portion 42 on the other end side. The tape winding portion 43 is formed as an electric wire fixing portion. In fig. 4 to 7, the electric wire 33 is not shown in part in order to show the shape of the tape winding portion 43. The protector main body 35 of the present embodiment is formed in a shape in which the direction of one end is slightly inclined with respect to the middle and the other end. Therefore, the lead-out portion 41 on the one end side is disposed in an inclined state. The harness outlet 44 is formed in a circular shape at an end of the lead-out portion 41 on one end side. The harness main body 29 is drawn out from the protector main body 35 along an axis (an axis of the lead-out portion 41 on one end side) passing through the center of the harness drawing-out opening 44. Although not particularly denoted by reference numerals, a portion that engages with an end of the bellows 34 is formed in the wire harness extraction port 44 (see fig. 11 and 12). Reference numeral 45 in the protector body 35 denotes a fixed portion with respect to the movable structure 24 (see fig. 1).

Likewise, the second disposition portion 55 is formed as a portion in which the harness main body 29 is disposed in the direction of the arrow R2. The third arrangement portion 56 is formed as a portion in which the harness main body 29 is arranged in the direction of the arrow R3. The two inclined portions 57 and 58 are formed as inclined surfaces (curved surfaces) that come into sliding contact when the harness main body 29 passes over the end portion intermediate portion 50 (see arrow R4), or when the harness main body 29 falls from the end portion intermediate portion 50 into the one side end portion 51 or the other side end portion 52 (see arrow R4). In addition, the first arrangement portion 54 is formed as follows: the wire harness main body 29 is put into a state of being housed when dropped, and at this time, the wire harness main body 29 can be held in a soft state.
The one end portion 51 is disposed apart from the leading portion 41 on the one end side, and is disposed in the vicinity of the fixed leg portion 48. The other end 52 is disposed on the side closer to the leading portion 41 on the one end side. The one end 51, the end intermediate 50, and the other end 52 are disposed at different positions at the extending direction end 46 of the harness guide 36. A harness sliding contact portion 60 that is in sliding contact with the harness main body 29 is formed at least in the end portion middle 50 of the extending direction end portion 46. The wire harness sliding contact portion 60 is formed in a chamfered shape or a curved shape. The arrangement changing portion 47 as described above is formed in a state where the surface thereof is the mirror surface 61. Further, a plurality of reinforcing ribs 62 are formed on the back surface side (see fig. 9).
< about the fixing leg portion 48 and the wall portion 49 >
In fig. 10 to 13, the fixed leg portion 48 is formed as a fixed portion with respect to the moving structure 24 (see fig. 1). The wall portion 49 is disposed on the guide side portion 63, and the guide side portion 63 is formed from the fixed leg portion 48 to the leading portion 41 on one end side. The wall portion 49 is formed as a portion that serves both as a configuration restriction of the harness main body 29 and a reinforcement of the configuration changing portion 47. In the present embodiment, the wall portion 49 is formed in a U-shape in cross section.
< action, Effect >
As described above with reference to fig. 1 to 14, according to the protector 28 and the wire harness routing structure 21 of the embodiment of the present invention, the arrangement changing portion 47 is formed in the wire harness guide portion 36, and therefore, the arrangement of the wire harness main body 29 in the wire harness guide portion 36 can be changed in accordance with the position of the moving structure 24 with respect to the fixed structure 23. Therefore, the harness main body 29 routed across the fixed structure 23 and the movable structure 24 can be smoothly moved by the arrangement changing portion 47 of the harness guide portion 36.
It is needless to say that the present invention can be variously modified within a range not changing the gist of the present invention.
