Description

【０００１】
【発明の属する技術分野】
本発明は、例えば自動車のスライドドアに常時給電を行わせるワイヤハーネスの車両ボディ−スライドドア間における屈曲方向及び屈曲半径を規制して干渉等を防ぐように構成した柔軟なハーネス用外装部材とそれを用いたハーネス配索構造に関するものである。
【０００２】
【従来の技術】
図７は、自動車のスライドドア４１の電装品や補機等に常時給電を行うべく、車両ボディ（図示せず）側からスライドドア側にワイヤハーネス４２を配索し、スライドドア側で合成樹脂製のプロテクタ４３内にワイヤハーネス４２を屈曲させて収容し、スライドドア４１の開閉に伴うワイヤハーネス４２の余長（弛み）を吸収させる構造を示すものである（例えば特許文献１参照）。
【０００３】
プロテクタ４３はドアパネル４９とドアトリム５０との間に配設されている。ワイヤハーネス４２はプロテクタ４３のスリット状の下部開口４４から導出されて車両ボディ側に向かい、プロテクタ４３の前部開口４５からスライドドア側の補機等に向けて配索されている。鎖線で示すワイヤハーネスは図８（平面図）のスライドドア４１の全閉状態に対応し、実線で示すワイヤハーネス４２は図９（平面図）のスライドドア４１の全開状態に対応している。
【０００４】
図８〜図９で、符号４６はハーネス固定部を示し、車両ボディ４７のステップ部４８に固定され、ワイヤハーネス４２はスライドドア４１の開閉に伴ってハーネス固定部４６を支点に前後に揺動する。符号５３は取っ手を示す。
【０００５】
スライドドア４１は図８の全閉時に車両ボディ４７と同一面に位置し、全閉から図２０の全開に移行する際に、車両ボディ４７から外向きに離間しつつ二次元的に後方に移動する。ワイヤハーネス４２は図８の全閉時に後方（ハーネス固定部４６側）に引っ張られ、図９の全開時に前方（ハーネス固定部側）に引っ張られる。

【発明が解決しようとする課題】
しかしながら、上記従来のスライドドア４１におけるハーネス配索構造にあっては、図８のスライドドア４１の全閉時には何ら問題ないが、図９の全開時に、プロテクタ４３の配設位置によっては、ワイヤハーネス４２がスライドドア４１と車両ボディ４７との間（渡り部５１）で鎖線で示す如く車両ボディ４７のセンターピラー５２等に干渉しやすくなるので、プロテクタ等の配設位置に注意が必要となり、必要以上に設計に時間を要した。また、万が一ワイヤハーネス４２が干渉した場合には、ワイヤハーネス４２の摩耗や変形等によって給電の信頼性が低下したり、プロテクタ内への収容性（余長吸収性）が悪化するという心配があった。
【０００８】
また、スライドドアへの給電に限らず、ワイヤハーネスを屈曲させつつ例えば車両ボディ等に配索する場合に、ワイヤハーネスを一方向に小さな半径で屈曲させ、他方向に大きな半径で屈曲させることで、他の構造物等との干渉を防ぐ必要が生じることがあり、その場合に、作業者が一々ワイヤハーネスの屈曲半径を考えながら配索を行うために、配索作業が面倒であり、しかも屈曲半径を変えることを忘れて配索を行った場合には、ワイヤハーネスが他の構造物等と干渉して摩耗や傷付きを生じるといった懸念があった。
【０００９】
また、ワイヤハーネスの外周に合成樹脂製のコルゲートチューブといった比較的剛性の高いハーネス用外装部材を装着した場合には、屈曲半径に限界があり、小さな半径で柔軟に屈曲させることが困難であった。
【００１０】
本発明は、上記した点に鑑み、スライドドア等の開閉時におけるワイヤハーネスと車両ボディ等との干渉を防止することができ、しかもワイヤハーネスを小さな半径で柔軟に屈曲させることのできるハーネス用外装部材を用いたハーネス配索構造を提供することを目的とする。
【００１１】
【課題を解決するための手段】
上記目的を達成するために、本発明の請求項１に係るハーネス用外装部材を用いたハーネス配索構造は、電線を挿通させる柔軟なハーネス用外装部材で、周方向の複数の凸条と該凸条間の凹溝とを長手方向に並列に配置して成る蛇腹部を備え、該蛇腹部の一側方に大きな内幅の凹溝が配置され、該蛇腹部の他側方の前半側に大きな内幅の凹溝が配置され、該他側方の後半側に小さな内幅の凹溝が配置されたハーネス用外装部材を用い、固定構造体から可動構造体に該電線を配索し、該固定構造体と可動構造体との間に該ハーネス用外装部材を配索し、該一側方を該可動構造体の閉じ側に配置し、該他側方を該可動構造体の開き側に配置し、該前半側を該可動構造体側に配置し、該後半側を該固定構造体側に配置することで、該可動構造体の全閉時に該ハーネス用外装部材を固定構造体側から小さな半径で屈曲させ、該可動構造体の全開時に、該ハーネス用外装部材を該固定構造体側から大きな半径で屈曲させ、且つ該可動構造体側から小さな半径で屈曲させることを特徴とする。
上記構成により、可動構造体の全閉時に、大きな内幅の凹溝を有する側が屈曲内側となって車両前方向に小さな屈曲半径で屈曲し、ハーネス用外装部材と可動構造体の内側トリムとの干渉が防止され、可動構造体の全開時に小さな内幅の凹溝を有する側が屈曲内側となって車両後方向に大きな屈曲半径で屈曲し、ハーネス用外装部材と固定構造体との干渉が防止される。
すなわち、ハーネス用外装部材が大きな内幅の凹溝を有する側を屈曲内側として一方向に小さな屈曲半径で屈曲し、小さな内幅の凹溝を有する側を屈曲内側として他方向に大きな屈曲半径で屈曲する。これは、大きな内幅の凹溝に隣接する凸条同士が大きく撓んだ位置で当接し、小さな内幅の凹溝に隣接する凸条同士が小さく撓んだ状態ですぐに当接するからである。
ハーネス用外装部材をスライドドアと車両ボディとの間（渡り部）において給電用ワイヤハーネスに装着した場合、スライドドアの全閉時に、大きな内幅の凹溝を有する側を屈曲内側として車両前方向に小さな屈曲半径で屈曲させ、スライドドアの全開時に小さな内幅の凹溝を有する側を屈曲内側として車両後方向に大きな屈曲半径で屈曲させることができ、これにより車両ボディとハーネス用外装部材との干渉が防止される。ハーネス用外装部材は柔軟性を有しているから、例えば小さな内幅の凹溝を有する側を屈曲内側とした場合に、凹溝に隣接する凸条同士が強く当接しても、凸条が凹んだり傷んだする心配がなく、たとえ凹んでもすぐに復元するから、ストレスがかからず初期形状が安定に保持される。
【００１２】
また、可動構造体の全開時に可動構造体側の例えばハーネス余長吸収装置に向けてハーネス用外装部材の前半部がスムーズに屈曲し、可動構造体の動きにスムーズに追従してハーネス用外装部材へのストレスが軽減される。
すなわち、ハーネス用外装部材が他側方を屈曲内側として後半の小さな内幅の凹溝によって大きな半径で屈曲し、それ同時に前半の大きな内幅の凹溝によって小さな半径で同方向に屈曲する。スライドドアの給電用ワイヤハーネスに適用した場合、スライドドアの全開時にハーネス用外装部材の後半部が車両ボディ側から大きな半径で屈曲し、前半部がスライドドア側から小さな半径で屈曲することで、ハーネス用外装部材と車両ボディとの干渉が防止されると共に、スライドドア側の例えばハーネス余長吸収装置に向けてハーネス用外装部材の前半部がスムーズに屈曲し、ハーネス用外装部材へのストレスが軽減される。
【００１３】
請求項２に係るハーネス用外装部材を用いたハーネス配索構造は、請求項１記載のハーネス用外装部材を用いたハーネス配索構造において、大きな外幅の凸条に隣接して前記小さな内幅の凹溝が形成され、小さな外幅の凸条に隣接して前記大きな内幅の凹溝が形成されたことを特徴とする。
上記構成により、大きな外幅の凸条と小さな外幅の凸条とを同一ピッチで形成し、両凸条の内面側の形状を同一にして、ハーネス用外装部材の成形金型の形状の簡素化を図ることができる。また、幅広の凸条同士の当接により、強い停止力を得ることができる。
【００１４】
請求項３に係るハーネス用外装部材を用いたハーネス配索構造は、請求項２記載のハーネス用外装部材を用いたハーネス配索構造において、前記大きな外幅の凸条の外面が断面矩形状に形成されたことを特徴とする。
上記構成により、幅広な凸条の外面が断面矩形状であるから、幅広な凸条と幅狭な凸条との外径を同一に設定して、幅広な凸条の外面と外部との干渉を防止することができる。また、幅広な凸条の外面は断面直線状の外周面を有するから、幅広な凸条を屈曲内側として大きな半径で屈曲させた際に、それ以上の屈曲が阻止され（屈曲しにくく）、上記車両ボディとの干渉が確実に防止される。
【００１５】
請求項４に係るハーネス用外装部材を用いたハーネス配索構造は、請求項２又は３記載のハーネス用外装部材を用いたハーネス配索構造において、前記大きな外幅の凸条と前記小さな外幅の凸条とのピッチが同じであり、一側方の小さな外幅の凸条と他側方の大きな外幅の凸条とが外径の１／２の位置で一体に続いていることを特徴とする。
上記構成により、大きさの異なる凸条が外径の１／２の位置で周方向に一体化されたことで、幅狭な凸条を屈曲内側とする場合と幅広な凸条を屈曲内側とする場合とでハーネス用外装部材の屈曲がそれぞれ正確な半径でスムーズに行われ、屈曲性が高まると共に、各凸条のピッチが同じであることで、成形金型の形状が簡素化され、ハーネス用外装部材の製造が容易化・低コスト化される。
【００１６】
請求項５に係るハーネス用外装部材を用いたハーネス配索構造は、請求項１〜４の何れか１項に記載のハーネス用外装部材を用いたハーネス配索構造において、前記ハーネス用外装部材が合成ゴムを材料として一体に形成されたことを特徴とする。
上記構成により、柔軟で且つ弾性を有するハーネス用外装部材を型抜き性良く容易に形成することができる。ハーネス用外装部材は弾性を有しているから、外部との干渉等によっても傷付きを生じにくく、内側の電線（ワイヤハーネス）を安全に保護する。
【００２０】
【発明の実施の形態】
図１〜図３は、本発明に係るハーネス用外装部材の一実施形態を示すものである。図１は平面図，図２は側面図、図３は図２のＡ−Ａ断面図をそれぞれ示している。
【００２１】
このハーネス用外装部材６０はＥＰＤＭ等の合成ゴムを材料として一体に形成され、長手方向前半の一側方と他側方とに通常の大きさの蛇腹状の凸条６１と凹溝６２とを有し、後半の一側方に通常の大きさの蛇腹状の凸条６１と凹溝６２とを有し、後半の他側方に幅広の凸条６３と幅狭の凹溝６４とを有するものである。各凸条６１，６３と凹溝６２，６４とで蛇腹部５６が構成されている。
【００２２】
通常の大きさの凸条６１や凹溝６２とは例えば車両用ワイヤハーネスの屈曲部分に通常使用される防水グロメットの蛇腹部の凸条や凹溝とほぼ同じ大きさ・形状の凸条や凹溝を意味し、特許請求の範囲では小さな外幅の凸条及び大きな内幅の凹溝と表現している。
【００２３】
幅広の凸条６３の外面は断面矩形状に形成され、隣接する各凸条６３の外面側の対向面６３ａが近接して位置し、ハーネス用外装部材６０の屈曲時に対向面６３ａ同士がすぐに当接して大きな屈曲半径を得るようになっている。凸条６３の外面は垂直な前後の対向面６３ａと、前後の対向面６３ａに直交する水平な周面６３ｃとで断面矩形状に構成されている。通常の大きさの凸条６１の外面は断面略円弧状に形成され、各凸条６１，６３の内面６１ａ，６３ｂ（図３）及び各凹溝６２，６４の谷部６２ａ，６４ａはそれぞれ断面略円弧状に形成されている。幅広の凸条６３及び凹溝６４は通常の凸条６１及び凹溝６２よりも厚肉に形成されて剛性を有している。幅狭の凹溝６４の深さは通常の凹溝６２よりも少し浅い。幅広の凸条６３の内面６３ｂと通常の大きさの凸条６１の内面６１ａの大きさ・形状は同じである。これにより、内側の成形金型（図示せず）の形状が一定で簡素化されている。
【００２４】
図１の如く幅広の凸条６３の径方向反対側に直角な段差部６９を介して通常の大きさの凸条６１が続き、幅広の凸条６３の間の幅狭の凹溝６４の径方向反対側に通常の大きさの凹溝６２が続いている。幅狭の凹溝６４の内幅Ｐ₁は通常の大きさの凹溝６２の内幅Ｐ₂の半分程度である。大小の凸条６１，６３や凹部６２，６４の切り替わり位置はハーネス用外装部材６０の中心線を通る平面上（５５）にある。各凸条６１，６３のピッチや山高さ（ハーネス用外装部材６０の外径）は蛇腹部５６の全長に渡って一定である。蛇腹部５６の長手方向中間部（前半と後半の境部）で幅広の凸条６３’は幅狭な凸条６１と一体化し、幅方向の一方に矩形状の外面部６３ｄ、他方に円弧状の外面部６１ｂをそれぞれ有している。
【００２５】
このハーネス用外装部材６０は例えば車両用の防水グロメット（図示せず）の蛇腹部を成形するための金型（特に外側の成形金型）に改良を加えることで簡単に成形可能である。材質がゴムであるから、合成樹脂材で同様なハーネス用外装部材を成形する場合のように製品を分割させる必要がない（合成樹脂材では型抜きが困難なために製品を分割せざるを得ない）。
【００２６】
ハーネス用外装部材６０の長手方向の両端部には、蛇腹部５６の外径よりも小径で蛇腹部５６の内径にほぼ等しい径の円筒状の部分６６，６７が形成され、例えば幅広の凸条６３に続く後端側の長めの筒状部６６が車両ボディ側のハーネス固定部６８（図４）内でワイヤハーネス５の外周にビニルテープ巻きで固定されたり、あるいはハーネス固定部６８内に回動自在に保持された回動部材（図示せず）に固定される。端部の凹溝６２，６４をハーネス固定部６８内の突条（図示せず）に係止させてもよい。
【００２７】
但し、ハーネス用外装部材６０がゴムで弾性を有するから、スライドドア２（図４）の開閉時に合成樹脂製のハーネス外装部材（図示せず）のように回動部材でハーネス用外装部材６０の捩れを吸収させる必要性は極めて少ない。通常の使用形態ではよほど大きな捩れが作用する場合以外は回動部材等の捩れ吸収機構は必要ない。前端側の短めの筒状部６７は例えばワイヤハーネス５の外周にテープ巻き等で固定される。あるいは筒条部６７を小径に形成して緊迫力でワイヤハーネス５に密着させてもよい。
【００２８】
図４〜図５は、上記ハーネス用外装部材６０を自動車のスライドドア給電用のワイヤハーネスに適用したハーネス配索構造の一形態を示すものである。
【００２９】
ワイヤハーネス５は予めハーネス用外装部材６０内に挿通され、ワイヤハーネス５の一方はスライドドア側の余長吸収装置２４を経てスライドドア内の各補機等に接続され、ワイヤハーネス５の他方は車両ボディ側のハーネス固定部（固定部材）６８を経て車両ボディ側（バッテリ側）のワイヤハーネス（図示せず）にコネクタ接続される。ハーネス用外装部材６０の一端はワイヤハーネス５に固定され、他端はハーネス固定部６８に固定ないし保持される。
【００３０】
図４の如くスライドドア２の全閉時にハーネス用外装部材６０の一側面の通常の大きさの各凸条６１が屈曲方向内側に位置して、ハーネス用外装部材６０の後半部がハーネス固定部６８を支点に車両ボディ側から小さな半径で車両前方に向けて（スライドドア閉じ方向に）スムーズに屈曲する。ハーネス用外装部６０の前半部はハーネス余長吸収装置に向けてほぼ真直に位置する。これにより、スライドドア２の合成樹脂製のドアトリム２ａの内面とハーネス用外装部材６０との干渉が防止される。
【００３１】
ワイヤハーネス５及びハーネス用外装部材６０はドアトリム２ａの内面に沿って外部に導出されている。ワイヤハーネス５は複数本の電線をテープ巻きで結束させたり、あるいは薄肉の柔軟なチューブで覆って構成されている。
【００３２】
図４のスライドドア２の全閉時には、図６（ａ）の如く屈曲内側の通常の大きさの各凸条６１が通常の大きさすなわち幅広の凹溝６２内の隙間によって大きな角度で屈曲した状態で相互に当接し、あるいは近接し、これによってハーネス用外装部材６０が一方向に小さな屈曲半径で屈曲する。その際、屈曲外側の幅広の凸条６３が屈曲内側の凸条６１と同一ピッチであるから幅狭の溝部６４から大きく開いて、屈曲をスムーズに行わせる。これは、幅広の凸条６３の内面側の形状（図３の内面６３ｂや谷部６４ａの形状）が通常の凸条６１の内面側の形状と同じに形成されていることからも助長される。
【００３３】
図５のスライドドア２の全開時には、後半部に幅広の凸条６３と幅狭な凹溝６４（図１）とを有するハーネス用外装部材６０の他側面が屈曲内側に位置して、幅広の凸条６３同士の当接によってハーネス固定部６８を支点に車両ボディ側から大きな半径で湾曲し、これによりハーネス用外装部材６０と車両ボディ３のセンタピラー８との干渉が防止される。
【００３４】
これと同時にハーネス用外装部材６０の他側面の前半部すなわちハーネス固定部６８から長手方向に遠く離れた側の通常の大きさの凸条６１と凹溝６２（図１）によって、ハーネス用外装部材６０の前半部がスライドドア内の余長吸収装置２４に向けて後半部よりも小さな半径でスムーズに屈曲する。すなわちハーネス用外装部材６０がスライドドア側で小径に屈曲する。
【００３５】
図５のスライドドア２の全開時には、図６（ｂ）の如く屈曲内側の幅広な各凸条６３が幅狭の凹溝６４内の小さな隙間によって小さな角度で屈曲した状態ですぐに当接し、これによってハーネス用外装部材６０が他方向に大きな屈曲半径で屈曲する。この際、屈曲外側の通常の凸条６１と凹溝６２はそれらの円弧形状によって小さな力で開いて屈曲をスムーズに行わせる。
【００３６】
図４，図５の余長吸収装置２４は例えば従来同様にプロテクタ内で板ばね（弾性部材）によってワイヤハーネス５を上向きに付勢して余長を吸収させるもの（特開２００１−３５４０８５公報参照）や、リールを巻きばねで付勢してワイヤハーネス５を巻き取ることで余長を吸収させるもの等が適宜使用される。
【００３７】
上記実施形態によれば、車両ボディ３やドアトリム２ａとの干渉によるハーネス外装部材６０の摩耗や傷付きの防止効果に加えて、材料にＥＰＤＭ等のゴムを使用することで安価なハーネス用外装部材６０を得ることができる。また、左右のスライドドア２で同じ品番のハーネス外装部材６０を共用することができ、経済的である。
【００３８】
なお、ハーネス用外装部材６０の幅広の凸条６３に代えて通常の大きさの凸条６１のピッチを小さくして凸条６１間の凹溝６２を幅狭にすることで、ハーネス用外装部材６０の大きな屈曲半径を得るようにすることも可能である。また、ハーネス用外装部材６０の使用形態によっては、ハーネス用外装部材６０の一側に通常の大きさの凸条６１と凹溝６２、他側の全長に渡って幅広の凸条６３と幅狭の凹溝６４のみを形成することも可能である。また、上記実施形態においては外周側に幅狭の凹溝６４を形成したが、内周側に幅狭の凹溝（６４）を形成して、逆方向の屈曲時に内周側の凸条（６３）同士を当接させるようにすることも可能である。また、ゴムに代えて他の弾性材料や柔軟材料を用いてハーネス用外装部材６０を一体成形することも可能である。
【００３９】
また、自動車のスライドドア以外のスライドドアと車両ボディ以外のボディとの間、あるいは回転式のドアとボディとの間でのワイヤハーネスの配索に上記ハーネス用外装部材６０を適用することも可能である。この場合、スライドドアやドアを可動構造体、車両ボディ又はボディを固定構造体と表現する。
【００４０】
可動構造体（２）への給電以外の使用形態として、ハーネス用外装部材６０を例えば車両ボディに配索する場合、例えばワイヤハーネスを車両ボディに沿って小さな半径で屈曲させつつ配索する場合は、ハーネス用外装部材６０の通常の大きさの凸条６１と凹溝６２を有する側を屈曲内側として配索し、ワイヤハーネスを大きな半径で屈曲させつつ配索する場合は、ハーネス用外装部材６０の幅広の凸条６３と幅狭の凹溝６４を有する側を屈曲内側として配索する。
【００４１】
これにより、車両ボディの曲線状の配索経路に合わせてワイヤハーネスを盲作業でも容易に且つ正確に配索することができる。この場合も、配索形態に応じてハーネス用外装部材６０の凸条６１，６３や凹溝６２，６４の大きさ・配置等が設定される。幅広の凸条６３と幅狭の凹溝６４の位置は後半に限らず前半又は中央部や中央寄りに設定される場合もあり得る。
【００４２】
【発明の効果】
以上の如く、請求項１記載の発明によれば、可動構造体の全開時に小さな内幅の凹溝を有する側を屈曲内側として車両後方向に大きな屈曲半径で屈曲させて、ハーネス用外装部材と固定構造体との干渉を防止することができるから、電線の摩耗や傷付きが防止され、可動構造体への給電の信頼性が向上する。すなわち、ハーネス用外装部材をスライドドアの給電用ワイヤハーネスに適用した場合に、スライドドアの全開時におけるハーネス用外装部材と車両ボディとの干渉が防止されるから、内側の電線の摩耗や傷付きが防止され、給電の信頼性が向上する。
【００４３】
また、可動構造体の全開時にハーネス用外装部材の前半を可動構造体に向けて小さな半径でスムーズに屈曲させることで、可動構造体のスムーズな開閉操作が可能となる。スライドドアの全開時にハーネス用外装部材の後半が大きな半径で屈曲して車両ボディとの干渉が防止され、ハーネス用外装部材の前半がスライドドアに向けて小さな半径で同方向にスムーズに屈曲して、スライドドアのスムーズな開閉操作が可能となる。
【００４４】
請求項２記載の発明によれば、幅広の凸条同士の当接により、強い停止力を得ることで、大きな屈曲半径を正確に保つことができ、上記車両ボディとの干渉防止効果が助長される。
【００４５】
請求項３記載の発明によれば、幅広な凸条の断面直線状の外周面によって、凸条同士の当接時に一層強い停止力が得られ、大きな屈曲半径が正確に保たれて、上記車両ボディとの干渉防止効果が一層助長される。
【００４６】
請求項４記載の発明によれば、幅狭な凸条を屈曲内側とする場合と幅広な凸条を屈曲内側とする場合とでハーネス用外装部材の屈曲がそれぞれ正確な半径でスムーズに行われ、ハーネス用外装部材の屈曲性が高まると共に、各凸条のピッチが同じになることで、成形金型の形状が簡素化され、ハーネス用外装部材の製造が容易化・低コスト化される。
【００４７】
請求項５記載の発明によれば、柔軟で且つ弾性を有するハーネス用外装部材を型抜き性良く容易に形成することができ、且つハーネス用外装部材は外部との干渉等によっても傷付きを生じにくく、内側の電線を安全に保護することができる。

BACKGROUND OF THE INVENTION
The present invention relates to a flexible harness exterior member configured to prevent interference and the like by regulating a bending direction and a bending radius between a vehicle body and a sliding door of a wire harness that constantly supplies power to a sliding door of an automobile, for example. The present invention relates to a harness routing structure using a cable.
[0002]
[Prior art]
FIG. 7 shows that the wire harness 42 is routed from the vehicle body (not shown) side to the sliding door side so as to always supply power to the electrical components and accessories of the sliding door 41 of the automobile, and synthetic resin is used on the sliding door side. A structure is shown in which a wire harness 42 is bent and accommodated in a protector 43, and the extra length (slack) of the wire harness 42 associated with opening and closing of the slide door 41 is absorbed (see, for example, Patent Document 1).
[0003]
The protector 43 is disposed between the door panel 49 and the door trim 50. The wire harness 42 is led out from the slit-like lower opening 44 of the protector 43 and is directed toward the vehicle body side, and is routed from the front opening 45 of the protector 43 toward the auxiliary equipment on the slide door side. A wire harness indicated by a chain line corresponds to the fully closed state of the slide door 41 in FIG. 8 (plan view), and a wire harness 42 indicated by a solid line corresponds to the fully open state of the slide door 41 in FIG. 9 (plan view).
[0004]
8-9, the code | symbol 46 shows a harness fixing | fixed part, is fixed to the step part 48 of the vehicle body 47, and the wire harness 42 rocks | fluctuates back and forth around the harness fixing | fixed part 46 as a fulcrum with opening / closing of the slide door 41. To do. Reference numeral 53 denotes a handle.
[0005]
The sliding door 41 is located on the same plane as the vehicle body 47 when fully closed in FIG. 8 and moves rearward in two dimensions while being spaced outward from the vehicle body 47 when shifting from the fully closed state to the fully opened state in FIG. To do. The wire harness 42 is pulled rearward (harness fixing portion 46 side) when fully closed in FIG. 8, and is pulled forward (harness fixing portion side) when fully opened in FIG.
[0006]

JP 2001-354085 A (7th to 9th pages, FIG. 4)
[0007]
[Problems to be solved by the invention]
However, in the conventional harness routing structure in the sliding door 41, there is no problem when the sliding door 41 of FIG. 8 is fully closed, but depending on the position of the protector 43 when the sliding door 41 of FIG. 42 is likely to interfere with the center pillar 52 of the vehicle body 47 between the slide door 41 and the vehicle body 47 (crossover portion 51) as indicated by a chain line, so it is necessary to pay attention to the position of the protector etc. More time was required for the design. In the unlikely event that the wire harness 42 interferes with the wire harness 42, there is a concern that the reliability of the power supply may be reduced due to wear or deformation of the wire harness 42, or the capacity (extra length absorption) in the protector may deteriorate. It was.

Also, not only for feeding power to the sliding door, but when wiring the wire harness while bending it, for example, in a vehicle body, the wire harness is bent with a small radius in one direction and bent with a large radius in the other direction. In such cases, it may be necessary to prevent interference with other structures.In that case, the wiring work is troublesome because the worker performs the wiring while considering the bending radius of the wire harness. When wiring is performed without forgetting to change the bending radius, there is a concern that the wire harness interferes with other structures and the like and wears or is damaged.
[0009]
In addition, when a relatively rigid harness exterior member such as a corrugated tube made of synthetic resin is attached to the outer periphery of the wire harness, there is a limit to the bending radius, and it is difficult to flex flexibly with a small radius .
[0010]
In view of the above, the present invention can prevent the interference between the wire harness and the vehicle body at the time of opening and closing of the slide door, etc. , and can flexibly bend the wire harness with a small radius. It aims at providing the harness wiring structure using a member.

DETAILED DESCRIPTION OF THE INVENTION
1 to 3 show an embodiment of a harness exterior member according to the present invention. 1 is a plan view, FIG. 2 is a side view, and FIG. 3 is a cross-sectional view taken along line AA of FIG.
[0021]
The harness exterior member 60 is integrally formed of synthetic rubber such as EPDM, and has a bellows-like ridge 61 and a groove 62 of normal size on one side and the other side of the first half in the longitudinal direction. And has a bellows-like convex strip 61 and a concave groove 62 of normal size on one side of the latter half, and a wide convex strip 63 and a narrow concave groove 64 on the other side of the latter half. Is. Each ridge 61, 63 and the concave grooves 62, 64 constitute a bellows portion 56.
[0022]
The ridges 61 and the grooves 62 having the normal size are, for example, ridges and grooves having substantially the same size and shape as the ridges and grooves of the bellows part of the waterproof grommet normally used for the bent portion of the vehicle wire harness. It means a groove, and in the claims, it is expressed as a convex line having a small outer width and a concave groove having a large inner width.
[0023]
The outer surface of the wide ridge 63 is formed in a rectangular shape in cross section, the opposing surface 63a on the outer surface side of each adjacent ridge 63 is located close to each other, and the opposing surfaces 63a are immediately formed when the harness exterior member 60 is bent. A large bending radius is obtained by contact. The outer surface of the ridge 63 is configured in a rectangular cross section with a vertical front and rear facing surface 63a and a horizontal peripheral surface 63c orthogonal to the front and rear facing surface 63a. The outer surface of the ridge 61 having a normal size is formed in a substantially arc-shaped cross section, and the inner surfaces 61a and 63b (FIG. 3 ) of the ridges 61 and 63 and the valleys 62a and 64a of the grooves 62 and 64 are respectively cross sections. It is formed in a substantially arc shape. The wide ridge 63 and the groove 64 are thicker than the normal ridge 61 and the groove 62 and have rigidity. The depth of the narrow groove 64 is slightly shallower than the normal groove 62. The size and shape of the inner surface 63b of the wide ridge 63 and the inner surface 61a of the ridge 61 having a normal size are the same. Thereby, the shape of the inner mold (not shown) is constant and simplified.
[0024]
As shown in FIG. 1, a normal ridge 61 continues through a step portion 69 perpendicular to the radial opposite side of the wide ridge 63, and the diameter of the narrow groove 64 between the wide ridges 63. Concave grooves 62 of normal size continue on the opposite side. The inner width P ₁ of the narrow groove 64 is about half of the inner width P ₂ of the normal groove 62. The switching positions of the large and small ridges 61, 63 and the concave portions 62, 64 are on a plane (55) passing through the center line of the harness exterior member 60. The pitch and the peak height (the outer diameter of the harness exterior member 60) of each ridge 61, 63 are constant over the entire length of the bellows portion 56. The wide ridge 63 'is integrated with the narrow ridge 61 in the middle portion in the longitudinal direction of the bellows portion 56 (the boundary between the first half and the second half), the rectangular outer surface portion 63d on one side in the width direction, and the arc shape on the other. The outer surface portion 61b is provided.
[0025]
The harness exterior member 60 can be easily formed by, for example, improving a mold (particularly an outer mold) for forming a bellows portion of a waterproof grommet (not shown) for a vehicle. Because the material is rubber, there is no need to divide the product as in the case of molding a similar harness exterior member with a synthetic resin material (since it is difficult to mold with a synthetic resin material, the product must be divided) Absent).
[0026]
Cylindrical portions 66 and 67 having a diameter smaller than the outer diameter of the bellows portion 56 and substantially equal to the inner diameter of the bellows portion 56 are formed at both ends of the harness exterior member 60 in the longitudinal direction. A long tubular portion 66 on the rear end side following 63 is fixed to the outer periphery of the wire harness 5 with a vinyl tape in a harness fixing portion 68 (FIG. 4) on the vehicle body side, or is wound around the harness fixing portion 68 . It is fixed to a rotating member (not shown) that is held movably. The end concave grooves 62 and 64 may be locked to a protrusion (not shown) in the harness fixing portion 68.
[0027]
However, since the harness exterior member 60 is made of rubber and has elasticity, the harness exterior member 60 is made of a rotating member such as a synthetic resin harness exterior member (not shown) when the slide door 2 (FIG. 4) is opened and closed. There is very little need to absorb twist. In a normal use form, a twist absorbing mechanism such as a rotating member is not required unless a very large twist acts. The short cylindrical portion 67 on the front end side is fixed to the outer periphery of the wire harness 5 by tape winding or the like, for example. Alternatively, the tubular portion 67 may be formed to have a small diameter, and may be brought into close contact with the wire harness 5 with an urging force.
[0028]

One end of the harness exterior member 60 is fixed to the wire harness 5, and the other end is fixed or held to the harness fixing portion 68.
[0030]
As shown in FIG. 4, when the sliding door 2 is fully closed, the normal ridges 61 on one side of the harness exterior member 60 are positioned on the inner side in the bending direction, and the rear half of the harness exterior member 60 is the harness fixing portion. 68 is smoothly bent toward the front of the vehicle (in the sliding door closing direction) with a small radius from the vehicle body side with 68 as a fulcrum. The front half of the harness exterior portion 60 is positioned substantially straight toward the harness surplus length absorber. Accordingly, interference between the inner surface of the synthetic resin door trim 2a of the slide door 2 and the harness exterior member 60 is prevented.
[0031]
The wire harness 5 and the harness exterior member 60 are led out to the outside along the inner surface of the door trim 2a. The wire harness 5 is constituted by bundling a plurality of electric wires by tape winding or covering them with a thin flexible tube.
[0032]
When the sliding door 2 shown in FIG. 4 is fully closed, as shown in FIG. 6 (a), the ridges 61 of the normal size inside the bend are bent at a large angle by the normal size, that is, the gap in the wide concave groove 62. The harness exterior member 60 bends in one direction with a small bending radius. At that time, the wide ridges 63 on the outer side of the bend have the same pitch as the ridges 61 on the inner side of the bend, so that the wide groove ridges 64 are opened widely, and the bending is smoothly performed. This is also facilitated by the fact that the shape on the inner surface side of the wide ridge 63 (the shape of the inner surface 63b and the valley portion 64a in FIG. 3) is the same as the shape on the inner surface side of the normal ridge 61. .
[0033]
When the sliding door 2 of FIG. 5 is fully opened, the other side surface of the harness exterior member 60 having the wide ridge 63 and the narrow concave groove 64 (FIG. 1) in the rear half is located on the bent inner side, Due to the contact between the ridges 63, the harness fixing portion 68 is bent at a large radius from the vehicle body side as a fulcrum, thereby preventing interference between the harness exterior member 60 and the center pillar 8 of the vehicle body 3.
[0034]
At the same time, the harness exterior member is formed by the normal ridges 61 and grooves 62 (FIG. 1) on the side far from the front half of the other side surface of the harness exterior member 60, that is, the harness fixing portion 68 in the longitudinal direction. The front half of 60 is smoothly bent toward the surplus length absorbing device 24 in the slide door with a smaller radius than the rear half. That is, the harness exterior member 60 bends to a small diameter on the slide door side.
[0035]
When the sliding door 2 of FIG. 5 is fully opened, the wide protruding ridges 63 on the bent inner side immediately come into contact with each other in a state of being bent at a small angle by a small gap in the narrow concave groove 64 as shown in FIG. As a result, the harness exterior member 60 is bent in the other direction with a large bending radius. At this time, the normal ridge 61 and the groove 62 on the outer side of the bend are opened with a small force by their arc shape, and the bend is smoothly performed.
[0036]
4 and 5, for example, as in the prior art, a surplus length is absorbed by urging the wire harness 5 upward by a leaf spring (elastic member) in a protector (see JP 2001-354085 A). ), Or a device that absorbs the extra length by urging the reel with a winding spring and winding the wire harness 5 is used as appropriate.
[0037]
According to the above-described embodiment, in addition to the effect of preventing wear and damage of the harness exterior member 60 due to interference with the vehicle body 3 and the door trim 2a, the exterior exterior member for harness is inexpensive by using rubber such as EPDM as a material. 60 can be obtained. Moreover, the harness exterior member 60 of the same product number can be shared by the left and right sliding doors 2, which is economical.
[0038]
In addition, it replaces with the wide protruding item | line 63 of the exterior member 60 for harnesses, and reduces the pitch of the protrusion 61 of a normal magnitude | size, and narrows the groove 62 between the protruding item | lines 61, and thereby the harness exterior member is narrowed. It is also possible to obtain a large bending radius of 60. Further, depending on how the harness exterior member 60 is used, the harness exterior member 60 may be provided with a normal ridge 61 and a groove 62 on one side, and a wide ridge 63 and a narrow width across the entire length of the other side. It is also possible to form only the concave groove 64. Moreover, in the said embodiment, although the narrow ditch | groove 64 was formed in the outer peripheral side, a narrow ditch | groove (64) was formed in the inner peripheral side, and the inner side ridge ( 63) It is also possible to bring them into contact with each other. In addition, the harness exterior member 60 can be integrally formed using another elastic material or a flexible material instead of rubber.
[0039]
Further, the harness exterior member 60 can be applied to the wiring harness between the sliding door other than the automobile sliding door and the body other than the vehicle body, or between the rotary door and the body. It is. In this case, the sliding door or door is expressed as a movable structure, and the vehicle body or body is expressed as a fixed structure.
[0040]
As a usage pattern other than power feeding to the movable structure (2), for example, when the harness exterior member 60 is routed in the vehicle body, for example, when the wire harness is bent while being bent along the vehicle body with a small radius, In the case where the side having the ridges 61 and the concave grooves 62 of the normal size of the harness exterior member 60 is routed as a bent inner side and the wire harness is routed while being bent at a large radius, the harness exterior member 60 The side having the wide ridge 63 and the narrow groove 64 is arranged as a bent inner side.
[0041]
As a result, the wire harness can be easily and accurately routed in a blind operation according to the curved routing route of the vehicle body. Also in this case, the size and arrangement of the ridges 61 and 63 and the grooves 62 and 64 of the harness exterior member 60 are set according to the wiring form. The positions of the wide ridges 63 and the narrow grooves 64 are not limited to the second half but may be set in the front half, the center, or near the center.
[0042]
