Description

ワイヤハーネス配索装置Wire harness wiring device
　本発明は、例えば、自動車の床などの車体と、この車体に対しスライド自在に設けられたシートなどのスライド体とに亘ってワイヤハーネスを配索するワイヤハーネス配索装置に関するものである。 The present invention relates to a wire harness routing device for routing a wire harness across a vehicle body such as a floor of an automobile and a slide body such as a seat slidably provided on the vehicle body.
　自動車には、車体としての乗員室の床などに対してスライド自在なスライド体としてのシートが設けられていることがある。また、前記シートには、例えば乗員が着座しているか否かを検出する着座センサ等の電子機器が取り付けられている。このため、前述したスライド自在なシートを有した自動車には、前記シートに取り付けられた電子機器と前記床に固定された電子機器とを接続するために、前記床と前記シートとに亘ってワイヤハーネスを配索する種々のワイヤハーネス配索装置が用いられてきた（例えば特許文献１を参照。）。 An automobile may be provided with a seat as a slide body that is slidable with respect to a floor of a passenger compartment as a vehicle body. In addition, an electronic device such as a seating sensor for detecting whether or not an occupant is seated is attached to the seat. For this reason, in order to connect the electronic device attached to the said sheet | seat and the electronic device fixed to the said floor to the motor vehicle which has the slidable sheet | seat mentioned above, a wire is passed over the said floor and the said sheet | seat. Various wire harness routing devices for routing a harness have been used (see, for example, Patent Document 1).
　例えば特許文献１に記載された上記ワイヤハーネス配索装置は、前記シートの足部を支持する支持体をスライド自在に取り付ける支持レールと平行に配置されたワイヤハーネスレールと、このワイヤハーネスレールにスライド自在に取り付けられかつ前記シートに連動してスライドするプロテクタと、を有している。前記支持レール及び前記ワイヤハーネスレールは、マットの下に配置されている。また、前記ワイヤハーネスレールは、ワイヤハーネスを取り付けた前記プロテクタをスライド自在に取り付けるプロテクタ移動部と、前記ワイヤハーネスの余長部分を収容する余長収容部と、を有している。前記プロテクタは、前記マットに設けられた切れ目を通されて乗員室側に突出しており、前記ワイヤハーネスの一端部を乗員室側に配置された前記シートに導く。 For example, the wire harness routing device described in Patent Document 1 includes a wire harness rail arranged in parallel with a support rail that slidably attaches a support that supports the foot portion of the seat, and slides on the wire harness rail. And a protector that is freely attached and slides in conjunction with the seat. The support rail and the wire harness rail are disposed below the mat. Moreover, the said wire harness rail has a protector moving part which attaches the said protector which attached the wire harness so that sliding is possible, and the surplus length accommodating part which accommodates the surplus length part of the said wire harness. The protector protrudes toward the passenger compartment through a slit provided in the mat, and guides one end of the wire harness to the seat disposed on the passenger compartment side.
　このような従来のワイヤハーネス配索装置においては、部品点数が多く、大きな設置スペースが必要になる上に、当該ワイヤハーネス配索装置が取り付けられる自動車のマットに、前記支持体を乗員室側に突出させるための切れ目の他に、前記プロテクタを乗員室側に突出させるための切れ目を設ける必要があり、数多くの切れ目をマットに設けなければならないという問題があった。 In such a conventional wire harness routing device, the number of parts is large, a large installation space is required, and the support is placed on the passenger compartment side on the mat of the automobile to which the wire harness routing device is attached. In addition to the cuts for projecting, it is necessary to provide cuts for projecting the protector toward the passenger compartment, and there is a problem in that many cuts must be provided on the mat.
　また、特許文献２に記載されたワイヤハーネス配索装置１００は、図１３に示すように、シート１０１の足部１０２を支持する支持体１０３と、この支持体１０３をスライド自在に取り付ける支持レール１０４と、ワイヤハーネス１０５の余長部分を渦巻状に巻き取った状態でハウジング１０７内に収容した巻取装置１０６と、を有している。 Further, as shown in FIG. 13, a wire harness routing device 100 described in Patent Document 2 includes a support body 103 that supports a foot portion 102 of a seat 101, and a support rail 104 that slidably mounts the support body 103. And a winding device 106 accommodated in a housing 107 in a state where the extra length of the wire harness 105 is wound in a spiral shape.
　この巻取装置１０６のハウジング１０７の導出口１０７ａから引き出されたワイヤハーネス１０５の一端部１０５ａは、支持レール１０４の一端部に位置する開口部から当該支持レール１０４内に引き込まれるとともに当該支持レール１０４内を通され、支持体１０３の内部空間に装着されたガイドパイプ（不図示）の内側を通され、そして、支持体１０３に設けられた穴を通されて支持体１０３外に引き出され、足部１０２に接続されている。また、図１３においては、前記マットは省略しているが、このマットには、支持レール１０４にスライド自在に取り付けられた支持体１０３を乗員室側に突出させるための切れ目が設けられている。 One end portion 105 a of the wire harness 105 drawn out from the outlet 107 a of the housing 107 of the winding device 106 is drawn into the support rail 104 through an opening located at one end portion of the support rail 104 and the support rail 104. It passes through the inside of a guide pipe (not shown) mounted in the internal space of the support body 103, passes through a hole provided in the support body 103, and is pulled out of the support body 103. Connected to the unit 102. In FIG. 13, the mat is omitted, but the mat is provided with a cut for projecting the support body 103 slidably attached to the support rail 104 toward the passenger compartment.
　上記巻取装置１０６は、図１４に示すように、ハウジング１０７と、リール１３２と、渦巻きスプリング１３３と、を有している。リール１３２は、ハウジング１０７の中央部に軸支されており、その中心部にはワイヤハーネス１０５の他端部１０５ｂが導出されて抜け止めされている。従って、ワイヤハーネス１０５は、リール１３２が一側に回転することでその外周面周りに巻き取られ、リール１３２が他側に回転することでその外周面周りから繰り出される。渦巻きスプリング１３３は、一端部がハウジング１０７に係止され、他端部がリール１３２に係止されている。この渦巻きスプリング１３３は、リール１３２を一側に回転させる付勢力を発生するためのものである。従って、ワイヤハーネス１０５は、この渦巻きスプリング１３３の付勢力によって巻き取られ、また、この付勢力に抗して繰り出されることで常に緊張状態に保持される。 As shown in FIG. 14, the winding device 106 includes a housing 107, a reel 132, and a spiral spring 133. The reel 132 is pivotally supported at the central portion of the housing 107, and the other end portion 105 b of the wire harness 105 is led out from the central portion to prevent the reel 132 from coming off. Accordingly, the wire harness 105 is wound around the outer peripheral surface when the reel 132 rotates to one side, and is fed out from the outer peripheral surface when the reel 132 rotates to the other side. One end of the spiral spring 133 is locked to the housing 107 and the other end is locked to the reel 132. The spiral spring 133 is for generating a biasing force that rotates the reel 132 to one side. Therefore, the wire harness 105 is wound up by the urging force of the spiral spring 133 and is always kept in a tensioned state by being drawn out against the urging force.
　このようなワイヤハーネス配索装置１００においては、支持レール１０４内にワイヤハーネス１０５を引き込むようにして、特許文献１に記載されたワイヤハーネスレールを省いているので、このワイヤハーネスレールの設置スペースが不要になる上に、マットに設けられる切れ目の数を少なくすることができる。 In such a wire harness routing device 100, the wire harness 105 described in Patent Document 1 is omitted by pulling the wire harness 105 into the support rail 104, so that the installation space for this wire harness rail is small. In addition to being unnecessary, the number of cuts provided in the mat can be reduced.

　しかしながら、図１３及び図１４に示されたワイヤハーネス配索装置１００は、上述したように非常に複雑な構成の巻取装置１０６が必要であるという問題があった。また、巻取装置１０６は、ハウジング１０７の一辺の寸法を、ハーネス１０５の渦巻状に巻き取られた部分の直径よりも小さくすることができず、さらに、リール１３２と渦巻きスプリング１３３の２段構造で厚みが必要となることから、大きな設置スペースが必要になるという問題があった。また、ワイヤハーネス配索装置１００は、支持体１０３の内部空間に前記ガイドパイプを装着したり、支持体１０３に前記ガイドパイプから引き出されたハーネス１０５の一端部１０５ａを通す前記穴（大きな穴）を設けなければならず、非常に複雑な構成の支持体１０３が必要であるという問題があった。また、前記ガイドパイプを支持体１０３に装着したり、装着されたガイドパイプにハーネス１０５を通す作業は、非常に煩雑で、容易に行える作業ではないという問題があった。 However, the wire harness routing device 100 shown in FIGS. 13 and 14 has a problem that the winding device 106 having a very complicated configuration is necessary as described above. Further, the winding device 106 cannot make the dimension of one side of the housing 107 smaller than the diameter of the portion of the harness 105 wound up in a spiral shape, and further has a two-stage structure of a reel 132 and a spiral spring 133. However, there is a problem that a large installation space is required because the thickness is required. Further, the wire harness routing device 100 attaches the guide pipe to the internal space of the support body 103, or passes the one end portion 105a of the harness 105 drawn from the guide pipe to the support body 103 (the large hole). There is a problem that the support body 103 having a very complicated configuration is necessary. In addition, the work of attaching the guide pipe to the support 103 or passing the harness 105 through the attached guide pipe is very complicated and not easy to perform.
　したがって、本発明は、大きな設置スペースを必要とせず、かつ、簡素な構成のワイヤハーネス配索装置を提供することを目的とする。 Therefore, an object of the present invention is to provide a wire harness routing device that does not require a large installation space and has a simple configuration.

Therefore, the wiring route of the wire harness 4 becomes a large circumference, that is, the bending radius becomes large, the wire harness 4 can be smoothly moved, and the wire harness 4 can be prevented from being tightly bent. Further, since the wire harness 4 is folded back in a U-shape in the same bending direction as that of the guide portion 58 in the parallel portion 31, the wire harness 4 is prevented from being bent into an S-shape. it can.
　また、本発明では、平行部３１内に収容されたワイヤハーネス４を案内部５８と上下に違った高さで交差させて余長収容部３外に引き出す第２案内部６０を有しているので、ワイヤハーネス４が余長収容部３から出し入れされる際に、これらワイヤハーネス４の交差した部分同士が擦れ合うことを防止できる。また、本実施形態では、第２案内部６０が案内部５８の下側に設けられている。 Moreover, in this invention, it has the 2nd guide part 60 which makes the wire harness 4 accommodated in the parallel part 31 cross | intersect with the guide part 58 at a different height up and down, and pulls it out of the surplus length accommodating part 3.

Moreover, both the support body 7 mentioned above and the derivation | leading-out part 84 of the protector 8 are passed through the cut | interruption 12a of the mat | matte 12. FIG.
　このように、本発明では、支持体７とプロテクタ８とをレール２の長手方向に沿って並ぶ配置とした上で、従来は支持体７のみをスライド自在に収容するものであったレール２内に、プロテクタ８及びワイヤハーネス４をスライド自在に収容しているので、プロテクタ８をスライド自在に取り付けるためのレール等を専用に設ける必要が無く、ワイヤハーネス配索装置１Ａを部品点数が少なくコンパクトで簡素な構成にすることができる。また、大きな設置スペースを必要としないワイヤハーネス配索装置１Ａとすることができる。また、従来は支持体７のみが通されるマット１２の切れ目１２ａに、支持体７とプロテクタ８の導出部８４、即ちワイヤハーネス４、の双方を通すことができ、マット１２に設けられる切れ目１２ａの数を少なくすることができる。 As described above, in the present invention, the support body 7 and the protector 8 are arranged side by side along the longitudinal direction of the rail 2, and conventionally, only the support body 7 is slidably accommodated in the rail 2. Furthermore, since the protector 8 and the wire harness 4 are slidably accommodated, there is no need to provide a dedicated rail or the like for slidably mounting the protector 8, and the wire harness routing device 1A has a small number of parts and is compact. A simple configuration can be achieved. Moreover, it can be set as 1A of wire harness wiring apparatuses which do not require a big installation space. Further, conventionally, both the support 7 and the lead-out portion 84 of the protector 8, that is, the wire harness 4 can be passed through the cut 12a of the mat 12 through which only the support 7 is passed, and the cut 12a provided in the mat 12 can be passed. Can be reduced.
　また、本発明では、プロテクタ８を用い、導出部８４によってワイヤハーネス４を保護しながら、該ワイヤハーネス４をレール２内を通して「スライド体」としてのシートに導いているので、ワイヤハーネス４のレール２への出し入れ、即ちレール２内での移動、を円滑に行うことができ、また、ワイヤハーネス４がレール２の角の部分（例えば内壁２５の下端の縁など）や支持体７などに当たって傷付くことを防止できる。 Further, in the present invention, the protector 8 is used and the wire harness 4 is guided to the seat as the “sliding body” through the rail 2 while protecting the wire harness 4 by the lead-out portion 84. The wire harness 4 can be smoothly moved in and out of the rail 2, that is, moved in the rail 2, and the wire harness 4 hits the corner portion of the rail 2 (for example, the edge of the lower end of the inner wall 25) or the support body 7 and is damaged. It can prevent sticking.
　また、本発明では、支持体７のプロテクタ固定部７４とプロテクタ８の支持体固定部８９とを突起部７４ｃとナット７６とで締め付けて固定する構成としているので、簡素な構成の支持体７及びプロテクタ８を用いることができ、また、容易に組み立てることができるワイヤハーネス配索装置１Ａとすることができる。 Further, in the present invention, the protector fixing portion 74 of the support body 7 and the support body fixing portion 89 of the protector 8 are fastened and fixed by the protrusion 74c and the nut 76, so that the support body 7 having a simple structure and The protector 8 can be used, and the wire harness routing device 1A can be easily assembled.
　さらに、本発明では、支持体固定部８９が、ワイヤハーネス取付部８０に取り付けられたワイヤハーネス４即ちコルゲートチューブ６の中心軸の延長線上に配置されているので、プロテクタ８及びワイヤハーネス４のスライド時に支持体固定部８９に作用する荷重方向がプロテクタ８のスライド方向（矢印Ｚ）と平行になり、そのために、プロテクタ８に生じるねじれを低減でき、このプロテクタ８の破損を回避することができる。また、「支持体固定部８９に作用する荷重」とは、ワイヤハーネス４の重力によるものである。 Furthermore, in the present invention, the support fixing portion 89 is disposed on the extension line of the central axis of the wire harness 4 attached to the wire harness attaching portion 80, that is, the corrugated tube 6, so that the protector 8 and the wire harness 4 slide. Sometimes the load direction acting on the support fixing portion 89 is parallel to the slide direction (arrow Z) of the protector 8, so that the torsion occurring in the protector 8 can be reduced and the breakage of the protector 8 can be avoided. The “load acting on the support fixing portion 89” is due to the gravity of the wire harness 4.
　また、本発明では、回転防止部８８を有しているので、突起部７４ｃとナット７６との締め付けが緩むことを防止でき、また、プロテクタ８の移動を円滑に行うことができる。また、この回転防止部８８は、支持体７とプロテクタ８とを固定することを目的とするものではなく、支持体固定部８９が回転することを防止するものであるので、支持体固定部８９のように突起部７４ｃとナット７６とで強固に締め付けてプロテクタ掛け部７５に固定する必要はない。即ち、凹状の部分と凸状の部分とが嵌まりあって引っ掛かる程度のもので良い。また、本実施形態では、支持体７に設けられた「凸部」としての柱部７５ｂに嵌まる柱部通し孔８８ｂが設けられた回転防止部８８を用いているが、本発明では、前記「回転防止部」を支持体７に設けられた「凹部」に嵌まる突起としても良い。 Further, in the present invention, since the rotation preventing portion 88 is provided, it is possible to prevent the tightening of the projection 74c and the nut 76 from being loosened, and the protector 8 can be moved smoothly. Further, the rotation preventing portion 88 is not intended to fix the support 7 and the protector 8, but prevents the support fixing portion 89 from rotating, and thus the support fixing portion 89. As described above, it is not necessary to firmly tighten the projection 74c and the nut 76 to fix the protector hook 75. That is, it is sufficient that the concave portion and the convex portion are fitted and caught. Further, in the present embodiment, the rotation preventing portion 88 provided with the column portion through-hole 88b that fits into the column portion 75b as the “convex portion” provided in the support body 7 is used. The “rotation preventing portion” may be a protrusion that fits into a “concave portion” provided in the support 7.
　上記構成のワイヤハーネス配索装置１Ａは、シート及び支持体７がレール２の一端部２ａ側から他端部２ｂ側に移動すると、プロテクタ８がこれらシート及び支持体７に連動して移動し、ワイヤハーネス４が余長収容部３から引き出されてハーネス収容部１３内に引き込まれる。また、シート及び支持体７がレール２の他端部２ｂ側から一端部２ａ側に移動すると、プロテクタ８がこれらシート及び支持体７に連動して移動し、ワイヤハーネス４がハーネス収容部１３から引き出されて余長収容部３内に引き込まれる。 In the wire harness routing device 1A configured as described above, when the seat and the support 7 are moved from the one end 2a side to the other end 2b side of the rail 2, the protector 8 is moved in conjunction with the seat and the support 7, The wire harness 4 is pulled out from the surplus length housing portion 3 and pulled into the harness housing portion 13. Further, when the seat and the support 7 are moved from the other end 2 b side of the rail 2 to the one end 2 a side, the protector 8 is moved in conjunction with the seat and the support 7, and the wire harness 4 is moved from the harness housing portion 13. It is pulled out and pulled into the extra length accommodating part 3.
