Description

本発明は、左右一対のスライドレールに沿って車両前後方向にスライド可能なシートのシートクッションの下面に配索されるハーネスを支持するシートのハーネス支持構造に関する。   The present invention relates to a harness support structure for a seat that supports a harness routed on a lower surface of a seat cushion of a seat that can slide in a vehicle longitudinal direction along a pair of left and right slide rails.

従来、自動車のシートに搭載された電装品のハーネスで電気的に接続する際に、シートを構成するシートクッションの下面にハーネスを配設し、ハーネスの垂れ下がりを防止するために、シートを昇降可能にして高さ調整するハイトアジャスタ機構の構成部材である車幅（左右）方向に長尺のトーションバーを利用し、トーションバーの途中に螺旋状のループさせた曲り部を形成し、その曲り部にハーネスを挿通することにより、ハーネスをトーションバーにより支持して垂れ下がりを防止することが提案されている（特許文献１参照）。   Conventionally, when electrically connecting with the harness of an electrical component mounted on an automobile seat, the harness can be placed on the lower surface of the seat cushion that constitutes the seat, and the seat can be raised and lowered to prevent the harness from sagging Using a torsion bar that is long in the vehicle width (left and right) direction, which is a component of the height adjuster mechanism that adjusts the height, a bent portion that is a spiral loop is formed in the middle of the torsion bar, and the bent portion It has been proposed that the harness is supported by a torsion bar to prevent the drooping by inserting the harness through (see Patent Document 1).

特開平８−２４２９６８号公報（要約、段落００２５および図１参照）JP-A-8-242968 (see abstract, paragraph 0025 and FIG. 1)

しかし、上記した特許文献１に記載のものでは、トーションバーを備えることが前提であり、トーションバーを備えない車種の場合には、トーションバーに相当する部材がなければハーネスの垂れ下がりを防止できないことになる。しかも、シートには前後方向にスライドするためのスライド機能が設けられており、シートをスライドさせるとシートの動きに連動してハーネスにたるみが生じることがあり、上記した特許文献１に記載のものでは、ハーネスが摩擦等によりトーションバーの曲り部を摺動しづらいため、シートの移動に伴いハーネスにたるみが生じても、ハーネスがトーションバーの曲り部を移動することによってたるみを吸収できず、たるみによるハーネスの垂れ下がりが生じるという不都合を解消できない。   However, in the above-described patent document 1, it is assumed that a torsion bar is provided, and in the case of a vehicle type that does not include a torsion bar, the harness cannot be prevented from drooping without a member corresponding to the torsion bar. become. In addition, the seat is provided with a slide function for sliding in the front-rear direction, and when the seat is slid, the harness may sag in conjunction with the movement of the seat. Then, since it is difficult for the harness to slide on the bent portion of the torsion bar due to friction or the like, even if the harness sags due to the movement of the seat, the harness cannot absorb the sag by moving the bent portion of the torsion bar. The inconvenience that the harness hangs down due to the slack cannot be solved.

本発明は、簡単な構成により、シートクッションの下面に配設されたハーネスの垂れ下がりとたるみを防止できるようにすることを目的とする。   An object of the present invention is to make it possible to prevent sagging and sagging of a harness disposed on the lower surface of a seat cushion with a simple configuration.

上記した目的を達成するために、本発明のシートのハーネス支持構造は、左右一対のスライドレールに沿って車両前後方向にスライド可能なシートのシートクッションの下面に配索されるハーネスを支持するシートのハーネス支持構造において、前記ハーネスの一端側が一方の前記スライドレールに固定され、前記ハーネスの他端側が他方の前記スライドレール付近に配置され、前記シートクッションに設けられ、前記ハーネスの中央部分が前後方向に移動自在に前記ハーネスを下方から支える支持手段を備えることを特徴としている（請求項１）。   In order to achieve the above object, the seat support structure for a seat according to the present invention is a seat that supports a harness routed on the lower surface of a seat cushion of a seat that can slide in the vehicle longitudinal direction along a pair of left and right slide rails. In the harness support structure, one end of the harness is fixed to one of the slide rails, the other end of the harness is disposed in the vicinity of the other slide rail, provided on the seat cushion, and a central portion of the harness is Supporting means for supporting the harness from below is provided so as to be movable in a direction (Claim 1).

請求項１に係る発明によれば、一端側が一方のスライドレールに固定され他端側が他方のスライドレール付近に配置されたハーネスを、その中央部分を下方から前後方向に移動自在に支える支持部材をシートクッションに設けたため、シートの前後方向へのスライドに伴いハーネスにたるみが生じても、支持手段の支持によりハーネスのたるみが吸収され、たるみと、たるみによるハーネスの垂れ下がりを同時に防止することができ、シートクッションの下方にスペースがない場合であっても、簡単な構成により、シートクッションの下面に配設されたハーネスの垂れ下がりとたるみを防止することが可能になる。このとき、支持手段として、例えば前後方向の帯状の布や金属板を用いるとよく、その他にも、シートクッションの下面を覆う下面側表皮を設ける場合には、その表皮に前後方向のスリットを形成し、そのスリットを介して表皮とシートクッション下面との間にハーネスの一部を挿入してハーネスを支持するようにし、表皮を支持手段として使用するのもよい。   According to the first aspect of the present invention, the support member that supports the harness that has one end fixed to one slide rail and the other end disposed near the other slide rail so that the central portion thereof is movable in the front-rear direction from below. Because it is provided on the seat cushion, even if the harness sags due to the sliding of the seat in the front-rear direction, the sag of the harness is absorbed by the support means, and it is possible to prevent sagging and sag of the harness due to sag simultaneously Even if there is no space below the seat cushion, it is possible to prevent sagging and sagging of the harness disposed on the lower surface of the seat cushion with a simple configuration. At this time, for example, a longitudinal belt-like cloth or a metal plate may be used as the support means. In addition, in the case where a lower surface skin that covers the lower surface of the seat cushion is provided, a longitudinal slit is formed in the skin. Then, a part of the harness may be inserted between the skin and the lower surface of the seat cushion through the slit to support the harness, and the skin may be used as a support means.

本発明に係るシートのハーネス支持構造を運転席側シートに適用した一実施形態について、図１ないし図３を参照して詳細に説明する。なお、本実施形態でいう前後、左右とはシートに着座した状態で見た前後、左右を意味する。   An embodiment in which a seat harness support structure according to the present invention is applied to a driver's seat side seat will be described in detail with reference to FIGS. 1 to 3. Note that front and rear and left and right in the present embodiment mean front and rear and left and right as viewed in a seated state on the seat.

図１は車両に搭載されたシート１を示し、前後方向にスライド自在に配設されたシートクッション１ａと、リクライニング機構によりシートバックフレームがシートクッションフレームに傾倒自在に結合されたシートバック１ｂと、シートバック１ｂに取り付けられたヘッドレスト１ｃとを備えている。ここで、車室フロアＦに設置された左右一対のフロア側スライドレール２ａとシートクッション１ａのシートクッションフレームに組み付けられたシート側スライドレール２ｂとの組み合わせを有するスライド機構３により、シート１が前後方向にスライドする。   FIG. 1 shows a seat 1 mounted on a vehicle, a seat cushion 1a that is slidable in the front-rear direction, a seat back 1b in which a seat back frame is tiltably coupled to a seat cushion frame by a reclining mechanism, And a headrest 1c attached to the seat back 1b. Here, the seat 1 is moved back and forth by a slide mechanism 3 having a combination of a pair of left and right floor side slide rails 2a installed on the passenger compartment floor F and a seat side slide rail 2b attached to a seat cushion frame of the seat cushion 1a. Slide in the direction.

このスライド機構３は、例えばシートクッション１ａの前下方に設けられたスライドハンドルをアンロック操作することにより、ロック機構のロックが解除されてシート１が前後方向にスライドすることができる状態になり、スライドハンドルのアンロック操作を止めると、ロック機構が作動してスライドレールに係止部材が係止し、シート１がスライド不能に保持される。   The slide mechanism 3 is in a state in which, for example, by unlocking a slide handle provided at the front lower side of the seat cushion 1a, the lock mechanism is unlocked and the seat 1 can slide in the front-rear direction. When the unlocking operation of the slide handle is stopped, the locking mechanism is activated, the locking member is locked to the slide rail, and the seat 1 is held so as not to slide.

そして、図２に示すように、シートベルトのシートバックル５に内蔵されたシートベルトセンサからの信号を、車両前部に設けられた車両制御用ＥＣＵ（Ｅｌｅｃｔｏｒｎｉｃ Ｃｏｎｔｒｏｌ Ｕｎｉｔ）に送信するために、シートベルトセンサと車両制御用ＥＣＵとがハーネス６により接続される。このとき、ハーネス６の右端にはコネクタ７ａが装着され、車両制御用ＥＣＵに接続されて右側のシート側スライドレール２ｂの取り付けられたコネクタ７ｂに、ハーネス６側のコネクタ７ａが嵌合するようになっており、ハーネス６の左端はシートバックル５のシートベルトセンサに接続されて左側のシート側スライドレール２ｂ付近に配置されている。   Then, as shown in FIG. 2, in order to transmit a signal from a seat belt sensor built in the seat buckle 5 of the seat belt to a vehicle control ECU (Electronic Control Unit) provided at the front of the vehicle, The belt sensor and the vehicle control ECU are connected by a harness 6. At this time, the connector 7a is attached to the right end of the harness 6, and the connector 7a on the harness 6 side is fitted to the connector 7b connected to the vehicle control ECU and attached to the right seat side slide rail 2b. The left end of the harness 6 is connected to the seat belt sensor of the seat buckle 5 and is disposed in the vicinity of the left seat side slide rail 2b.

また、シートクッション１ａの下面を覆う下面側表皮９が設けられており、この表皮９のほぼ中央に前後方向のスリット１０が形成され、シートクッション１ａの下面に沿って配設されたハーネス６の左半部が、スリット１０を介して表皮９の上方であって表皮９とシートクッション１ａの下面との間に挿入されるように配設され、表皮９によりハーネス６がその中央から左半部にわたって支持されている。このように、スリット１０を有する表皮９が、ハーネス６を前後方向に移動自在に支持する本発明の支持手段の役割を果たす。   Also, a lower surface side skin 9 that covers the lower surface of the seat cushion 1a is provided, and a slit 10 in the front-rear direction is formed substantially at the center of the skin 9, and the harness 6 disposed along the lower surface of the seat cushion 1a. The left half is disposed so as to be inserted above the skin 9 via the slit 10 and between the skin 9 and the lower surface of the seat cushion 1a. Is supported over. Thus, the skin 9 having the slit 10 serves as the support means of the present invention for supporting the harness 6 movably in the front-rear direction.

いま、シート１が図２の状態から図３に示すように前方にスライドされると、シート１の移動によりシートバックル５も一緒に前方に移動するため、ハーネス６の左端もシート１に連動して前方に移動する。このとき、コネクタ７ａ，７ｂの嵌合により固定されたハーネス６の右端側はほとんど移動せず、ハーネス６の左端側が移動するが、ハーネス６の左半部がハーネス６は表皮９とシートクッション１ａの下面との間で移動することになり、表皮９とシートクッション１ａの下面との間でハーネス６が覆われることにより、ハーネス６のたるみや垂れ下がりが外部に現れることがない。   Now, when the seat 1 is slid forward from the state of FIG. 2 as shown in FIG. 3, the seat buckle 5 moves forward together with the movement of the seat 1, so the left end of the harness 6 is also interlocked with the seat 1. To move forward. At this time, the right end side of the harness 6 fixed by the fitting of the connectors 7a and 7b hardly moves, and the left end side of the harness 6 moves, but the left half of the harness 6 has the outer skin 9 and the seat cushion 1a. When the harness 6 is covered between the skin 9 and the lower surface of the seat cushion 1a, sagging or sagging of the harness 6 does not appear outside.

したがって、上記した実施形態によれば、ハーネス６の左半部を表皮９に形成したスリット１０を介して表皮９とシートクッション１の下面との間に配設したため、シート１の前後方向へのスライドに伴いハーネス６にたるみが生じても、表皮９によりハーネス６の左半部を覆うことによってハーネス６のたるみが外部に現れることを防止でき、ハーネス６のたるみと垂れ下がりを同時に防止することができる。その結果、構造的にシートクッション１ａの下方にスペースがない車両であっても、既設の表皮９にスリット１０を形成するという簡単な構成により、シートクッション１ａの下面に配設されたハーネス６の垂れ下がりとたるみを防止することができる。   Therefore, according to the above-described embodiment, the left half of the harness 6 is disposed between the skin 9 and the lower surface of the seat cushion 1 via the slit 10 formed in the skin 9, so that the seat 1 in the front-rear direction is arranged. Even if sagging occurs in the harness 6 due to sliding, the sagging of the harness 6 can be prevented from appearing outside by covering the left half of the harness 6 with the skin 9, and the sagging and sagging of the harness 6 can be prevented simultaneously. it can. As a result, even if the vehicle structurally has no space below the seat cushion 1a, the harness 6 disposed on the lower surface of the seat cushion 1a can be formed by a simple configuration in which the slit 10 is formed in the existing skin 9. It is possible to prevent sagging and sagging.

なお、本発明は上記した実施形態に限定されるものではなく、その趣旨を逸脱しない限りにおいて上述したもの以外に種々の変更を行なうことが可能であり、例えば上記した実施形態では、シートバックル５に内蔵されたシートベルトセンサを電気的に接続するハーネル６に本発明を適用した場合について説明したが、その他の電装品用のハーネスであってシートクッション１ａの下面に配設されるものにも適用可能である。   The present invention is not limited to the above-described embodiment, and various modifications other than those described above can be made without departing from the spirit thereof. For example, in the above-described embodiment, the seat buckle 5 Although the case where the present invention is applied to the Harnel 6 that electrically connects the seat belt sensor incorporated in the seat is described, it is also a harness for other electrical components that is disposed on the lower surface of the seat cushion 1a. Applicable.

また、上記した実施形態では、表皮９を支持手段とした場合について説明したが、支持手段は、例えばシートクッション１ａの下面に設けられた前後方向の帯状の布や金属板であってもよく、これら帯状の布や金属板によりハーネス６の中央部分を下方から前後方向に移動自在に支持すればよい。   In the above-described embodiment, the case where the skin 9 is used as the support means has been described. However, the support means may be, for example, a belt-like cloth or a metal plate in the front-rear direction provided on the lower surface of the seat cushion 1a. What is necessary is just to support the center part of the harness 6 so that it can move to the front-back direction from the downward direction by these strip | belt-shaped cloth and a metal plate.

また、上記した実施形態では、本発明を運転席側シートに適用した例を示したが、助手席側シート或いは後部シートにも適用できるのはいうまでもない。   In the above-described embodiment, an example in which the present invention is applied to a driver's seat side seat has been described. However, it goes without saying that the present invention can also be applied to a passenger seat side seat or a rear seat.
