ワイヤハーネス配索装置Wire harness wiring device
　本明細書に開示される技術は、ワイヤハーネス配索装置に関する。 The technology disclosed herein relates to a wire harness routing device.
　従来、自動車等の車両には、スライド可能なシートが備えられており、このシートには電動リクライニング装置やシートヒータなどの電装品が装備されているものがある。これらの電装品と車体側の機器等との間を接続するワイヤハーネスは、シートと車体との間でシートのスライドに追従するため、シートと車体との間にワイヤハーネスの余長を収容する構成が備えられている。特許文献１には、シート下の空間に、シート側から延びるワイヤハーネスを導くスライダをシートの移動と連動してスライド可能に取り付ける移動部と、移動部の一端側から引き出されたワイヤハーネスの余長部分をＵ字形状に折り返した状態で収容する収容部と、を有する電線配索装置が開示されている。収容部は移動部の隣に並べられており、Ｕ字形状に折り返されたワイヤハーネスの余長部は移動部に対して横並びの状態で収容部内に収容されている。 2.

A configuration is provided. Patent Document 1 discloses a moving unit that slidably attaches a slider that guides a wire harness extended from the seat side to a space under the seat in conjunction with the movement of the sheet, and excess of the wire harness drawn from one end side of the moving unit. There is disclosed a wire routing device having a housing portion for housing a long portion in a U-shaped folded state.

特開２０１４－３９０２号公報JP, 2014-3902, A
　ところで、特許文献１の構成では、上述したようにワイヤハーネスの余長を収容するための収容部が必要であるが、収容部の分だけ車両における使用可能なスペースが少なくなるという問題があった。 By the way, in the configuration of Patent Document 1, as described above, the accommodating portion for accommodating the extra length of the wire harness is required, but there is a problem that the usable space in the vehicle is reduced by the amount of the accommodating portion. .
　本明細書に開示された技術は上記のような事情に基づいて完成されたものであって、ワイヤハーネスの余長を収容する収容部を小型化することを目的とする。 The technique disclosed in the present specification is completed based on the above-described circumstances, and an object thereof is to miniaturize the accommodating portion for accommodating the extra length of the wire harness.
　本明細書に開示される技術は、レールに対してスライド可能に取り付けられたスライダに連結されたワイヤハーネスと、前記ワイヤハーネスを前記レールの側方かつ前記レールに沿う方向に案内する案内部と、前記レールの側方に並んで設けられ、前記案内部によって案内された前記ワイヤハーネスを内部に収容する収容部と、を備え、前記ワイヤハーネスは前記収容部内において、上下方向に折り返された状態で前記スライダの移動に伴って移動可能に収容されているワイヤハーネス配索装置である。 The technology disclosed in the present specification includes a wire harness connected to a slider slidably attached to a rail, and a guide unit for guiding the wire harness in the lateral direction of the rail and along the rail. And an accommodating portion provided side by side with the rail and accommodating the wire harness guided by the guiding portion inside, wherein the wire harness is folded back in the vertical direction in the accommodating portion. The wire harness arranging device is accommodated so as to be movable with the movement of the slider.
　上記構成によれば、ワイヤハーネスは収容部内において上下方向に折り返された縦型の状態でレールに沿うように収容されているから、従来のように横方向（レールと並ぶ方向）に湾曲させて折り返す構成と比較して、収容部が必要とする床の設置面積が小さくなる。すなわち、車両における使用可能なスペースが従来よりも広くなる。 According to the above configuration, since the wire harness is accommodated along the rail in the vertical state in which the wire harness is folded back in the vertical direction, the wire harness is curved in the lateral direction (the direction in line with the rail) as in the prior art Compared to the folded configuration, the floor area required by the housing is smaller. That is, the usable space in the vehicle becomes wider than before.
　上記ワイヤハーネス配索装置は、以下の構成を備えていてもよい。 The said wire harness wiring apparatus may be equipped with the following structures.
　ワイヤハーネスは複数本の電線を有するとともに、当該複数本の電線が一列に並べられて扁平な形状とされており、収容部内において上方および下方に向けて扁平な面が配される向きで収容されている構成としてもよい。 The wire harness has a plurality of electric wires, and the plurality of electric wires are arranged in a line to form a flat shape, and is accommodated in a direction in which the flat surface is disposed upward and downward in the accommodation portion The configuration may be
　このような構成によれば、ワイヤハーネスが複数本の電線を有する場合でも、ワイヤハーネスを上下方向に簡単に折り返すことが可能となり、収容部の高さも低く抑えることができる。 According to such a configuration, even when the wire harness has a plurality of electric wires, the wire harness can be easily folded back in the vertical direction, and the height of the housing portion can be suppressed to a low level.
　ワイヤハーネスは複数本の電線の周囲を外装体により被覆してなり、外装体は一方向にのみ曲げが許容されている構成としてもよい。 The wire harness may be formed by covering the periphery of a plurality of electric wires with an outer package, and the outer package may be configured to be allowed to bend in only one direction.
　上記一方向とは、ワイヤハーネスの折り返し方向である。したがって、このような構成によれば、上下方向に折り返されたワイヤハーネスのうち上段に配されるワイヤハーネスの重力による撓みを大幅に軽減することができるから、収容部側に撓みを規制する構成が不要となり、収容部を簡易な構成とすることができる。 The above one direction is the turning direction of the wire harness. Therefore, according to such a configuration, bending due to gravity of the wire harness disposed on the upper stage of the wire harness folded back in the vertical direction can be significantly reduced, so that the deflection is restricted on the housing portion side Can be eliminated, and the storage unit can be configured simply.
　本明細書に開示される技術によれば、ワイヤハーネスの余長を収容する収容部を小型化することができる。 According to the technology disclosed in the present specification, it is possible to miniaturize the accommodating portion that accommodates the extra length of the wire harness.

Each electric wire 12 can use the coated electric wire by which the metal conductor parts which consist of copper, copper alloy, aluminum, aluminum alloy etc. were coat | covered with the insulating layer.
　外装体１３は例えば合成樹脂製であって、図２に示すように、複数の角筒部１４の連なりで構成されている。角筒部１４は複数本の電線１２を内部に収容可能な扁平な形態をなしており、一方向にのみ湾曲可能に形成されている。 The exterior body 13 is made of, for example, a synthetic resin, and as shown in FIG. 2, is composed of a series of a plurality of square tube portions 14. The rectangular tube portion 14 has a flat shape that can accommodate a plurality of electric wires 12 therein, and is formed to be bendable only in one direction.
　より詳細には、角筒部１４は、図３に示すように、一対の長壁と一対の短壁により囲まれた全体として断面略長方形の収容空間１５を有している。収容空間１５のうち角筒部１４の軸の断面方向から見た短辺の長さ寸法（図３のＬ１）は、複数本の電線１２を一列に収容可能な長さ寸法に設定されている。すなわち、電線１２の直径の２倍より小さい寸法に設定されている（本実施形態では直径とほぼ同等）。一方、長辺の長さ寸法（図３のＬ２）は、内側に収容する複数本の電線１２の直径の合計よりも余裕をもって大きく設定されている。これにより、収容空間１５内に収容された複数本の電線１２は、電線１２の並び方向（左右方向、Ｘ方向）には余裕をもって移動可能であり、一方、電線１２の並び方向と直交する方向（Ｙ方向）にはほぼ移動しないように、すなわち、一列に並べられるようになっている。 More specifically, as shown in FIG. 3, the rectangular tube portion 14 has a housing space 15 having a generally rectangular cross section surrounded by a pair of long walls and a pair of short walls. The length dimension (L1 in FIG. 3) of the short side of the accommodation space 15 as viewed from the cross-sectional direction of the axis of the rectangular tube portion 14 is set to a length dimension that can accommodate a plurality of electric wires 12 in a row. .

　本実施形態のワイヤハーネス配索装置１０は上記構成であって、次に、作用効果について説明する。 The wire harness arranging device 10 of the present embodiment has the above-described configuration, and the operation and effect will be described next.
　本実施形態のワイヤハーネス配索装置１０は、レール２０に対してスライド可能に取り付けられたスライダ３０に連結されたワイヤハーネス１１と、ワイヤハーネス１１をレール２０の側方の隣接する位置、かつ、レール２０に沿う方向（Ｚ方向）に案内するガイド部材４０と、レール２０の側方に並んで設けられ、ガイド部材４０によって案内されたワイヤハーネス１１を内部に収容する余長収容部５０と、を備えており、ワイヤハーネス１１は余長収容部５０内において、上下方向に折り返された縦型の状態でスライダ３０の移動に伴って移動可能に収容されている。 The wire harness routing apparatus 10 according to the present embodiment includes a wire harness 11 connected to a slider 30 slidably attached to a rail 20, and an adjacent position on the side of the rail 20 of the wire harness 11; A guide member 40 for guiding in a direction (Z direction) along the rail 20, and an extra length accommodating portion 50 which is provided side by side with the rail 20 and accommodates therein the wire harness 11 guided by the guide member 40; The wire harness 11 is accommodated in the extra length accommodating portion 50 so as to be movable along with the movement of the slider 30 in a vertical state folded back in the vertical direction.
　このような構成によれば、ワイヤハーネス１１は余長収容部５０内において上下方向に折り返された縦型の状態でレール２０に沿うように収容されているから、従来のように横方向（レール２０と並ぶ方向）に湾曲させて折り返す構成と比較して、余長収容部５０が必要とする床の設置面積が小さくなる。すなわち、車両における使用可能なスペースが従来よりも広くなる。 According to such a configuration, since the wire harness 11 is accommodated along the rail 20 in the vertical state folded back in the vertical direction in the extra length accommodating portion 50, the horizontal direction (rail As compared with the configuration of bending and folding back in the direction of line 20, the floor installation area required by the extra length storage portion 50 is reduced. That is, the usable space in the vehicle becomes wider than before.
　また、ワイヤハーネス１１は複数本の電線１２を有するとともに、当該複数本の電線１２が一列に並べられて扁平な形状とされており、余長収容部５０内において上方および下方に向けて扁平な面が配される向きで収容されている。 Further, the wire harness 11 has a plurality of electric wires 12, and the plurality of electric wires 12 are arranged in a line to form a flat shape, and in the extra length storage portion 50, the wire is flat upward and downward. It is housed in the direction in which the face is arranged.
　このような構成によれば、ワイヤハーネス１１が複数本の電線１２を有する場合でも、ワイヤハーネス１１を上下方向に簡単に折り返すことが可能となり、余長収容部５０の高さも低く抑えることができる。 According to such a configuration, even when the wire harness 11 has a plurality of electric wires 12, the wire harness 11 can be easily folded back in the vertical direction, and the height of the extra length storage portion 50 can also be suppressed low. .
　また、ワイヤハーネス１１は複数本の電線１２の周囲を外装体１３により被覆してなり、外装体１３は一方向にのみ曲げが許容されている。 Moreover, the wire harness 11 covers the circumference | surroundings of the several electric wire 12 with the exterior body 13, and the exterior body 13 is permitted to bend only in one direction.
　この一方向とは、ワイヤハーネス１１の折り返し方向である。したがって、このような構成によれば、上下方向に折り返されたワイヤハーネス１１のうち上段に配される上段部１１Ａの重力による撓みを大幅に軽減することができるから、余長収容部５０側に撓みを規制する構成が不要となり、余長収容部５０を簡易な構成とすることができる。 This one direction is the direction in which the wire harness 11 is folded back. Therefore, according to such a configuration, it is possible to significantly reduce the deflection due to the gravity of the upper end portion 11A disposed on the upper end of the wire harness 11 folded back in the vertical direction, so The configuration for restricting the deflection is not necessary, and the extra length storage portion 50 can be simplified.
