Abstract

This vehicle seat 1 comprises: a touch switch which is provided on the rear of a seat back; a slide motor which causes a seat cushion to move back and forth in parallel; a reclining motor which causes the seat back to tilt and move; and a control device. The control device performs a walk-in operation on the basis of a signal from the touch switch. The walk-in operation is an operation for moving the seat cushion and the seat back from an initial position to a walk-in position by simultaneously performing the forward tilting movement of the seat back and the forward parallel movement of the seat cushion. The vehicle seat 1 allows even a person having weak muscle strength to easily conduct walk-in operations, and allows even a person having no idea how to conduct the walk-in operations to intuitively conduct the proper walk-in operations.

　本発明は、従来装置における上記の問題点に鑑みて成されたものであって、筋力の弱い者でも容易にウォークイン操作を行うことができ、さらに、ウォークイン操作の仕方を知らない者でも直感的な操作によって適切なウォークイン操作を行うことができる車両用シートを提供することを目的とする。 The present invention has been made in view of the above problems in the conventional apparatus, and even a person with weak muscles can easily perform a walk-in operation, and even a person who does not know how to perform the walk-in operation. An object of the present invention is to provide a vehicle seat capable of performing an appropriate walk-in operation by an intuitive operation.
　本発明に係る車両用シートは、着座者の臀部が乗るシートクッションと、前記シートクッションの後部に設けられたシートバックとを有する車両用シートにおいて、前記シートバックの背面及び／又は側面に設けられたタッチスイッチと、前記シートクッションを前後方向へ平行移動させるシートクッション平行移動手段と、前記シートバックを前記シートクッションに対して前後方向へ傾斜移動させるシートバック傾斜移動手段と、前記タッチスイッチからの信号を受け取って前記シートクッション平行移動手段及び前記シートバック傾斜移動手段の動作を制御する制御装置とを有しており、前記制御装置は、前記タッチスイッチからの信号に基づいて、ウォークイン動作を実行し、前記ウォークイン動作は、着座者の着座動作を許容する位置である初期位置にある前記シートクッション及び前記シートバックに関して、前記シートバックの前傾移動と前記シートクッションの前方への平行移動とを同時に又は連続して行って、前記シートクッション及び前記シートバックをウォークイン位置へ移動させる動作であることを特徴とする。 A vehicle seat according to the present invention is a vehicle seat having a seat cushion on which a seated person's buttocks rides and a seat back provided at a rear portion of the seat cushion. From the touch switch, a seat cushion parallel moving means for moving the seat cushion in the front-rear direction, a seat back inclination moving means for moving the seat back in the front-rear direction with respect to the seat cushion, and the touch switch A control device that receives a signal and controls the operation of the seat cushion parallel movement means and the seat back tilt movement means, and the control device performs a walk-in operation based on a signal from the touch switch. And the walk-in operation allows a seated person to sit down. With respect to the seat cushion and the seat back at the initial position, the seat cushion and the seat back are moved forward or backward and the parallel movement forward of the seat cushion is performed simultaneously or continuously. It is the operation | movement which moves to a walk-in position.
　従来の車両用シートでは、操作者が操作レバーを機械的に操作することによってウォークイン動作を行っていた。しかしながら、この方法では、老人や子供のように筋力が弱い者にとっては操作レバーの操作が重労働であった。また、レバーの操作に慣れていない者にとっては、操作の仕方が分かり難かった。 In conventional vehicle seats, an operator performs a walk-in operation by mechanically operating an operation lever. However, in this method, the operation of the operation lever has been a heavy labor for those with weak muscle strength, such as elderly people and children. Also, for those who are not familiar with lever operation, it was difficult to understand how to operate.
　これに対し、本発明の車両用シートでは、操作者はタッチスイッチに触れるだけでウォークイン動作を実現でき、力を要する作業は不要である。従って、筋力の弱い者でも楽にウォークイン動作を実現できる。また、タッチスイッチを用いた操作は直感的な操作なので、操作に慣れていない人でも容易にウォークイン動作を実現できるようになった。 On the other hand, in the vehicle seat of the present invention, the operator can realize the walk-in operation only by touching the touch switch, and no work requiring force is required. Therefore, even a person with weak muscular strength can easily realize the walk-in operation. In addition, since the operation using the touch switch is an intuitive operation, even a person who is not familiar with the operation can easily realize the walk-in operation.
　本発明に係る車両用シートの１つの発明態様において、前記シートバックはヘッドレストを有しており、前記タッチスイッチはそのヘッドレストの背面及び／又は側面に具備されている。タッチスイッチがヘッドレストに設けられていると、操作者は操作を行い易い。 In one aspect of the vehicle seat according to the present invention, the seat back includes a headrest, and the touch switch is provided on a back surface and / or a side surface of the headrest. If the touch switch is provided on the headrest, the operator can easily perform the operation.
　本発明に係る車両用シートの他の１つの発明態様において、前記制御装置は、前記タッチスイッチからの信号に基づいて復帰動作を実行し、前記復帰動作は、前記ウォークイン位置にある前記シートクッション及び前記シートバックを前記初期位置へ復帰させる動作であることを特徴とする。 In another aspect of the vehicle seat according to the present invention, the control device performs a return operation based on a signal from the touch switch, and the return operation is performed at the seat cushion at the walk-in position. And the operation of returning the seat back to the initial position.
　本発明の車両用シートにおいては、ウォークイン位置にセットされた車両用シートを初期位置へ復帰させる際に、操作者は手動によってその復帰作業を行うことができる。しかしながら、この方法は、筋力の弱い者にとって重労働になる可能性がある。これに対し、本発明態様のように、ウォークイン動作後の車両用シートに関して操作者がタッチスイッチに触れるだけでその車両用シートの復帰動作を実現できるようにすれば、筋力の弱い者でもウォークイン動作の復帰動作を極めて楽に行うことができるので、非常に便利である。 In the vehicle seat of the present invention, when returning the vehicle seat set at the walk-in position to the initial position, the operator can manually perform the return operation. However, this method can be hard work for those with weak muscles. On the other hand, if the operator can realize the returning operation of the vehicle seat only by touching the touch switch with respect to the vehicle seat after the walk-in operation, as in the aspect of the present invention, even a person with weak muscles can walk. Since the return operation of the in operation can be performed very easily, it is very convenient.
　本発明に係る車両用シートのさらに他の１つの発明態様において、前記タッチスイッチは、操作者が触れたことを検知できるスイッチであり、前記制御装置は、操作者が前記タッチスイッチに触れている時間を計測し、この時間の長さに基づいて、前記シートクッションの移動速度及び／又は前記シートバックの移動速度を調節する。この構成により、操作者は、ウォークイン動作を完了させるための時間を状況に応じて調節できるようになった。しかも、そのための操作が直感的で分かり易くなった。 In still another aspect of the vehicle seat according to the present invention, the touch switch is a switch that can detect that the operator has touched, and the control device has the operator touching the touch switch. Time is measured, and the moving speed of the seat cushion and / or the moving speed of the seat back is adjusted based on the length of the time. With this configuration, the operator can adjust the time for completing the walk-in operation according to the situation. Moreover, the operation for that is intuitive and easy to understand.
　本発明に係る車両用シートのさらに他の１つの発明態様において、前記タッチスイッチは、操作者が触れている力の大きさを検知できるスイッチであり、前記制御装置は、操作者が前記タッチスイッチに触れている力の大きさを計測し、この力の大きさに基づいて、前記シートクッションの移動速度及び／又は前記シートバックの移動速度を調節する。この構成によれば、タッチスイッチに触れている時間に関係なく、接触力だけによってウォークイン動作の速度を調節できるので、操作の仕方がより一層直感的になって操作し易くなった。 In still another aspect of the vehicle seat according to the present invention, the touch switch is a switch capable of detecting the magnitude of a force touched by an operator, and the control device is configured so that the operator can detect the touch switch. The magnitude of the force touching the vehicle is measured, and the moving speed of the seat cushion and / or the moving speed of the seat back is adjusted based on the magnitude of the force. According to this configuration, since the speed of the walk-in operation can be adjusted only by the contact force regardless of the time during which the touch switch is touched, the operation method becomes more intuitive and easy to operate.
　本発明の車両用シートによれば、操作者はタッチスイッチに触れるだけでウォークイン動作を実現でき、力を要する作業は不要である。従って、筋力の弱い者でも楽にウォークイン動作を実現できる。また、タッチスイッチを用いた操作は直感的な操作なので、操作に慣れていない人でも容易にウォークイン動作を実現できるようになった。 According to the vehicle seat of the present invention, the operator can realize the walk-in operation only by touching the touch switch, and no work requiring force is required. Therefore, even a person with weak muscular strength can easily realize the walk-in operation. In addition, since the operation using the touch switch is an intuitive operation, even a person who is not familiar with the operation can easily realize the walk-in operation.

The control device 32 of FIG. 6 determines whether or not the vehicle is stopped based on the signal from the host computer 41 of FIG. 6 in step S1 of FIG. If the vehicle is stopped (YES in step S1), the process proceeds to step S2 to determine whether the door is open based on a signal from the host computer 41.
　制御装置３２は、ドアが開いていれば（ステップＳ２でＹＥＳ）、ステップＳ３へ進んで図６の着座センサ４２の出力信号に基づいて操作者Ｈ（図５（ａ）参照）から見て前席が空いているかどうかを判断する。前席が空いていれば（ステップＳ３でＹＥＳ）、制御装置３２は、
　　（１）ステップＳ４へ進んで前席が初期位置Ｐ１（図５（ａ）参照）にあることを判断するか、
　　（２）ステップＳ５へ進んで前席がウォークイン位置Ｐ２（図５（ｂ）参照）へ向かう途中で停止していることを判断するか、
　　（３）ステップＳ６へ進んで前席がウォークイン位置Ｐ２にあることを判断するか、あるいは
　　（４）ステップＳ７へ進んで前席がウォークイン位置Ｐ２から初期位置Ｐ１へ復帰する途中で停止しているかどうかを判断する。 If the door is open (YES in step S2), the control device 32 proceeds to step S3 and sees it from the operator H (see FIG. 5A) based on the output signal of the seating sensor 42 in FIG. Determine if seats are available. If the front seat is vacant (YES in step S3), the control device 32
(1) Proceed to step S4 to determine that the front seat is at the initial position P1 (see FIG. 5A),
(2) Proceed to step S5 to determine that the front seat is stopped on the way to the walk-in position P2 (see FIG. 5B),
(3) Proceed to step S6 to determine that the front seat is at the walk-in position P2, or (4) proceed to step S7 and stop while the front seat returns from the walk-in position P2 to the initial position P1. Determine if you are.
　前席が初期位置Ｐ１（図５（ａ）参照）にあると判断されるか（ステップＳ４でＹＥＳ）、あるいは、前席がウォークイン位置Ｐ２（図５（ｂ）参照）へ向かう途中で停止していると判断されるか（ステップＳ５でＹＥＳ）すると、制御装置３２はステップＳ８へ進んで図５（ａ）の操作者Ｈがタッチスイッチ３３に触れているかどうかを判断する。 Whether the front seat is determined to be in the initial position P1 (see FIG. 5A) (YES in step S4), or the front seat stops on the way to the walk-in position P2 (see FIG. 5B) If it is determined that it is determined (YES in step S5), the control device 32 proceeds to step S8 and determines whether or not the operator H in FIG.
　操作者Ｈがタッチスイッチ３３に触れていると判断されると（ステップＳ８でＹＥＳ）、制御装置３２はウォークインの起動動作を行うことに関して待機状態になる（ステップＳ９）。次に、制御装置３２は、操作者Ｈがタッチスイッチ３３に触れている時間を計測する（ステップＳ１０）。 If it is determined that the operator H is touching the touch switch 33 (YES in step S8), the control device 32 enters a standby state for performing a walk-in activation operation (step S9). Next, the control device 32 measures the time during which the operator H is touching the touch switch 33 (step S10).
　操作者Ｈがタッチスイッチ３３に触れている時間が所定の設定時間ｔｓ以上であれば（ステップＳ１０でＹＥＳ）、制御装置３２はリクライニングモータ１４及び／又はスライドモータ２５を高速で回転させて車両用シート１を初期位置Ｐ１（図５（ａ））からウォークイン位置Ｐ２（図５（ｂ））へ向けて高速に移動させる（ステップＳ１１）。 If the time during which the operator H is touching the touch switch 33 is equal to or longer than the predetermined set time ts (YES in step S10), the control device 32 rotates the reclining motor 14 and / or the slide motor 25 at high speed. The sheet 1 is moved at high speed from the initial position P1 (FIG. 5A) toward the walk-in position P2 (FIG. 5B) (step S11).
　車両用シート１の移動の態様として、次の態様が考えられる。
　（ア）シートクッション２（リクライニング）とシートバック３（スライド）を同時に目的位置へ向けて移動させる。
　（イ）シートバック３（リクライニング）が目的位置に到達したことを検知してシートクッション２がスライドを開始する。
　（ウ）シートクッション２（スライド）が目的位置に到達したことを検知してシートバック３がリクライニング動作を開始する。
　なお、「目的位置」とは、リクライニング及びスライドの作動限界位置や、制御装置３２によって定められた停止位置である。 The following modes can be considered as modes of movement of the vehicle seat 1.
(A) The seat cushion 2 (reclining) and the seat back 3 (slide) are simultaneously moved toward the target position.
(A) When the seat back 3 (reclining) reaches the target position, the seat cushion 2 starts to slide.
(C) When the seat cushion 2 (slide) has reached the target position, the seat back 3 starts the reclining operation.
The “target position” is a reclining and sliding operation limit position or a stop position determined by the control device 32.
　他方、ステップＳ１０において、操作者Ｈがタッチスイッチ３３に触れている時間が所定の設定時間ｔｓ未満であれば（ステップＳ１０でＮＯ）、制御装置３２はリクライニングモータ１４及び／又はスライドモータ２５を低速で回転させて車両用シート１を初期位置Ｐ１（図５（ａ））からウォークイン位置Ｐ２（図５（ｂ））へ向けてゆっくりと移動させる（ステップＳ１２）。 On the other hand, if the time that the operator H is touching the touch switch 33 is less than the predetermined set time ts in step S10 (NO in step S10), the control device 32 operates the reclining motor 14 and / or the slide motor 25 at a low speed. The vehicle seat 1 is slowly moved from the initial position P1 (FIG. 5A) toward the walk-in position P2 (FIG. 5B) (step S12).
　次に、制御装置３２はステップＳ１３において、図５（ａ）の操作者Ｈがタッチスイッチ３３に追加的に触れたかどうかを判断する。操作者Ｈがタッチスイッチ３３に追加的に触れていれば（ステップＳ１３でＹＥＳ）、制御装置３２はリクライニングモータ１４及びスライドモータ２５を停止する（ステップＳ１４）。また、制御装置３２は車両用シート１が図５（ｂ）のウォークイン位置Ｐ２へ到達したと判断すると（ステップＳ１５でＹＥＳ）、リクライニングモータ１４及びスライドモータ２５を停止する（ステップＳ１４）。 Next, in step S13, the control device 32 determines whether or not the operator H in FIG. If the operator H is additionally touching the touch switch 33 (YES in step S13), the control device 32 stops the reclining motor 14 and the slide motor 25 (step S14). If the control device 32 determines that the vehicle seat 1 has reached the walk-in position P2 in FIG. 5B (YES in step S15), the control device 32 stops the reclining motor 14 and the slide motor 25 (step S14).
　以上により、図５（ａ）の初期位置Ｐ１から図５（ｂ）のウォークイン位置Ｐ２への車両用シート１のウォークイン動作が実現される。 Thus, the walk-in operation of the vehicle seat 1 from the initial position P1 in FIG. 5A to the walk-in position P2 in FIG. 5B is realized.
（復帰動作）
　制御装置３２は、ステップＳ６で前席がウォークイン位置Ｐ２（図５（ｂ））に置かれていると判断するか（ステップＳ６でＹＥＳ）、あるいは、ステップＳ７で前席が復帰途中で停止していると判断するか（ステップＳ７でＹＥＳ）すると、ステップＳ１６へ進んで図５（ｂ）のタッチスイッチ３３に操作者Ｈが触れたかどうかを判断する。操作者Ｈがタッチスイッチ３３に触れていると判断すると（ステップＳ１６でＹＥＳ）、制御装置３２はウォークインの復帰動作を行うことに関して待機状態になる（ステップＳ１７）。 (Return operation)
The control device 32 determines in step S6 that the front seat is placed at the walk-in position P2 (FIG. 5B) (YES in step S6), or stops in the middle of returning the front seat in step S7. If it is determined that it is determined (YES in step S7), the process proceeds to step S16, and it is determined whether or not the operator H touches the touch switch 33 in FIG. If it is determined that the operator H is touching the touch switch 33 (YES in step S16), the control device 32 enters a standby state for performing the return operation of the walk-in (step S17).
　次に、制御装置３２は、操作者Ｈがタッチスイッチ３３に触れている時間を計測する（ステップＳ１０）。操作者Ｈがタッチスイッチ３３に触れている時間が所定の設定時間ｔｓ以上であれば（ステップＳ１０でＹＥＳ）、制御装置３２はリクライニングモータ１４及び／又はスライドモータ２５を復帰のために高速で回転させて車両用シート１をウォークイン位置Ｐ２（図５（ｂ））から初期位置Ｐ１（図５（ａ））へ向けて高速に移動させる（ステップＳ１１）。なお、ウォークイン動作時の「ｔｓ」と復帰時の「ｔｓ」は、同じでも良く、違っていても良い。 Next, the control device 32 measures the time during which the operator H is touching the touch switch 33 (step S10). If the time during which the operator H is touching the touch switch 33 is equal to or longer than the predetermined set time ts (YES in step S10), the control device 32 rotates the reclining motor 14 and / or the slide motor 25 at high speed for returning. Then, the vehicle seat 1 is moved at high speed from the walk-in position P2 (FIG. 5B) toward the initial position P1 (FIG. 5A) (step S11). Note that “ts” during the walk-in operation and “ts” during the return may be the same or different.
　他方、ステップＳ１０において、操作者Ｈがタッチスイッチ３３に触れている時間が所定の設定時間ｔｓ未満であれば（ステップＳ１０でＮＯ）、制御装置３２はリクライニングモータ１４及び／又はスライドモータ２５を低速で回転させて車両用シート１をウォークイン位置Ｐ２（図５（ｂ））から初期位置Ｐ１（図５（ａ））へ向けてゆっくりと移動させる（ステップＳ１２）。 On the other hand, if the time that the operator H is touching the touch switch 33 is less than the predetermined set time ts in step S10 (NO in step S10), the control device 32 operates the reclining motor 14 and / or the slide motor 25 at a low speed. The vehicle seat 1 is slowly moved from the walk-in position P2 (FIG. 5B) toward the initial position P1 (FIG. 5A) (step S12).
　次に、制御装置３２はステップＳ１３において、図５（ｂ）の操作者Ｈがタッチスイッチ３３に追加的に触れたかどうかを判断する。操作者Ｈがタッチスイッチ３３に追加的に触れていれば（ステップＳ１３でＹＥＳ）、制御装置３２はリクライニングモータ１４及びスライドモータ２５を停止する（ステップＳ１４）。また、制御装置３２は復帰する車両用シート１が図５（ａ）の初期位置Ｐ１へ到達したと判断すると（ステップＳ１５でＹＥＳ）、リクライニングモータ１４及びスライドモータ２５を停止する（ステップＳ１４）。 Next, in step S13, the control device 32 determines whether or not the operator H in FIG. If the operator H is additionally touching the touch switch 33 (YES in step S13), the control device 32 stops the reclining motor 14 and the slide motor 25 (step S14). If it is determined that the returning vehicle seat 1 has reached the initial position P1 in FIG. 5A (YES in step S15), the control device 32 stops the reclining motor 14 and the slide motor 25 (step S14).
　以上により、図５（ｂ）のウォークイン位置Ｐ２から図５（ａ）の初期位置Ｐ１への車両用シート１の復帰動作が実現される。 Thus, the return operation of the vehicle seat 1 from the walk-in position P2 in FIG. 5B to the initial position P1 in FIG. 5A is realized.
　本実施形態の車両用シート１において、図１のシートクッション２を前後方向へ平行移動させるための「シートクッション平行移動手段」は、図２のスライドモータ２５と、シートクッション２を平行移動させるための構造によって構成されている。シートクッション２を平行移動させるための構造は、本実施形態では、図３のロアレール１８と、アッパレール２０とによって構成されている。 In the vehicle seat 1 of the present embodiment, the “seat cushion translation means” for translating the seat cushion 2 in FIG. 1 in the front-rear direction is for translating the slide motor 25 in FIG. 2 and the seat cushion 2 in parallel. It is constituted by the structure. In the present embodiment, the structure for moving the seat cushion 2 in parallel is constituted by the lower rail 18 and the upper rail 20 shown in FIG.
　また、シートバック３をシートクッション２に対して前後方向へ傾斜移動させる「シートバック傾斜移動手段」は、図２のリクライニングモータ１４と、シートバック用骨格構造１１をシートクッション用骨格構造８に対して傾斜移動可能に支持する機構とによって構成されている。 Further, the “seat back tilt moving means” for moving the seat back 3 in the front-rear direction with respect to the seat cushion 2 includes the reclining motor 14 of FIG. 2 and the skeleton structure 11 for the seat back with respect to the skeleton structure 8 for the seat cushion. And a mechanism for supporting the tilt movement.
（変形例１）
　上記の実施形態では、図７のステップＳ１０からステップＳ１１で示したように、リクライニングモータ１４及び／又はスライドモータ２５の回転速度は、速いか遅いかの２通りであった。しかしながら、これに代えて、操作者がタッチスイッチ３３に触れている時間の長さに応じて、モータの回転速度を無段階的に又は段階的に変化させるようにしても良い。 (Modification 1)
In the above embodiment, as shown in steps S10 to S11 in FIG. 7, the rotational speeds of the reclining motor 14 and / or the slide motor 25 are two kinds of fast and slow. However, instead of this, the rotational speed of the motor may be changed steplessly or stepwise according to the length of time the operator is touching the touch switch 33.
（変形例２）
　上記の実施形態では、タッチスイッチ３３がシートバック３のシートバック本体５の上部に設けられていた。これに代えて、図４Ｂに示すようにタッチスイッチ３３をシートバック３のヘッドレスト４の背面に設けても良い。また、図４Ｃに示すようにタッチスイッチ３３をヘッドレスト４の側面に設けても良い。また、タッチスイッチ３３をシートバック本体５の側面に設けることもできる。 (Modification 2)
In the above embodiment, the touch switch 33 is provided on the upper portion of the seat back body 5 of the seat back 3. Instead, a touch switch 33 may be provided on the back surface of the headrest 4 of the seat back 3 as shown in FIG. 4B. Further, as shown in FIG. 4C, the touch switch 33 may be provided on the side surface of the headrest 4. The touch switch 33 can also be provided on the side surface of the seat back body 5.
（変形例３）
　上記の実施形態では、ウォークイン動作及び復帰動作の両方をタッチスイッチ３３を用いたスイッチング動作に基づいて行った。これに代えて、ウォークイン動作はタッチスイッチ３３を用いて行い、復帰動作は人力によって行ってもよい。なお、人力によって復帰動作を行う場合には、シートクッション２とシートバック３との間に復帰動作を可能とする機構を設けておく必要がある。 (Modification 3)
In the above embodiment, both the walk-in operation and the return operation are performed based on the switching operation using the touch switch 33. Alternatively, the walk-in operation may be performed using the touch switch 33, and the return operation may be performed manually. In the case where the return operation is performed manually, it is necessary to provide a mechanism that enables the return operation between the seat cushion 2 and the seat back 3.
（実施形態の作用効果）
　従来の車両用シートでは、操作者が操作レバーを機械的に操作することによってウォークイン動作を行っていた。しかしながら、この方法では、老人や子供のように筋力が弱い者にとっては操作レバーの操作が重労働であった。また、レバーの操作に慣れていない者にとっては、操作の仕方が分かり難かった。 (Effect of embodiment)
In a conventional vehicle seat, an operator performs a walk-in operation by mechanically operating an operation lever. However, in this method, the operation of the operation lever has been a heavy labor for those with weak muscle strength, such as elderly people and children. Also, for those who are not familiar with lever operation, it was difficult to understand how to operate.
　これに対し、本実施形態の車両用シート１では、操作者Ｈはタッチスイッチ３３に触れるだけでウォークイン動作を実現でき、力を要する作業は不要である。従って、筋力の弱い者でも楽にウォークイン動作を実現できる。また、タッチスイッチ３３を用いた操作は直感的な操作なので、操作に慣れていない人でも容易にウォークイン動作を実現できるようになった。 On the other hand, in the vehicle seat 1 of the present embodiment, the operator H can realize the walk-in operation only by touching the touch switch 33, and no work requiring force is required. Therefore, even a person with weak muscular strength can easily realize the walk-in operation. Further, since the operation using the touch switch 33 is an intuitive operation, even a person who is not familiar with the operation can easily realize the walk-in operation.
　次に、従来の車両用シートでは、ウォークイン位置Ｐ２（図５（ｂ））にセットされた車両用シート１を初期位置Ｐ１（図５（ａ））へ復帰させる際には、操作者Ｈが手動によって行っていた。しかしながら、この方法は筋力の弱い者にとって重労働であった。これに対し、本実施形態の車両用シート１では、ウォークイン動作後の車両用シート１（図５（ｂ））を操作者Ｈがタッチスイッチ３３に触れるだけで車両用シート１の復帰動作を実現できるので、筋力の弱い者でもウォークイン動作の復帰動作を極めて楽に行うことができるようになった。 Next, in the conventional vehicle seat, when the vehicle seat 1 set in the walk-in position P2 (FIG. 5B) is returned to the initial position P1 (FIG. 5A), the operator H Had been done manually. However, this method was hard work for those with weak muscles. On the other hand, in the vehicle seat 1 of the present embodiment, the return operation of the vehicle seat 1 is performed simply by the operator H touching the touch switch 33 on the vehicle seat 1 (FIG. 5B) after the walk-in operation. Because it can be realized, it has become possible to perform the return operation of the walk-in operation very easily even for those with weak muscle strength.
　次に、本実施形態の車両用シート１においては、図７のステップＳ１０からＳ１２に示したように、タッチスイッチ３３に対する接触時間に応じてウォークインの起動動作の速さ及びウォークインの復帰動作の速さを調節している。これにより、操作者Ｈは、ウォークイン動作を完了させるための時間を状況に応じて調節できるようになった。しかも、そのための操作が直感的で分かり易くなった。 Next, in the vehicle seat 1 of the present embodiment, as shown in steps S10 to S12 of FIG. 7, the speed of the walk-in activation operation and the walk-in return operation according to the contact time with respect to the touch switch 33. The speed of the is adjusted. Thereby, the operator H can adjust the time for completing the walk-in operation according to the situation. Moreover, the operation for that is intuitive and easy to understand.
（車両用シートの第２の実施形態）
　図８は、本発明に係る車両用シートの第２の実施形態の主要部である制御フローチャートを示している。本実施形態に係る車両用シートの機械的な構造は、図１から図４Ａに示した先の実施形態と同じとすることができる。また、本実施形態に係る車両用シートの電気的な構造は、図６に示した先の実施形態と同じとすることができる。 (Second embodiment of vehicle seat)
FIG. 8 shows a control flowchart which is a main part of the second embodiment of the vehicle seat according to the present invention. The mechanical structure of the vehicle seat according to this embodiment can be the same as that of the previous embodiment shown in FIGS. 1 to 4A. Moreover, the electrical structure of the vehicle seat according to the present embodiment can be the same as that of the previous embodiment shown in FIG.
　図８に示す本実施形態と図７に示した先の実施形態とで異なる点は、次の点である。すなわち、先の実施形態では、図７のステップＳ１０からＳ１２に示したように操作者Ｈ（図５（ａ）及び図５（ｂ））がタッチスイッチ３３に触れている時間の長さに応じてウォークイン動作の速度を調節した。 The difference between the present embodiment shown in FIG. 8 and the previous embodiment shown in FIG. 7 is as follows. That is, in the previous embodiment, as shown in steps S10 to S12 in FIG. 7, the operator H (FIGS. 5A and 5B) depends on the length of time that the touch switch 33 is touched. Adjusted the speed of the walk-in operation.
　これに対し、本実施形態では、図８のステップＳ６０からＳ６２に示すように、操作者Ｈ（図５（ａ）及び図５（ｂ））がタッチスイッチ３３に触れたときの力の大きさが設定値ｆｓよりも大きいか、あるいは小さいかによってウォークイン動作の速度を調節することにしている。具体的には、タッチスイッチ３３に対する接触力が設定値ｆｓ以上であるときはウォークイン動作の起動速度及び復帰速度を高速にし、タッチスイッチ３３に対する接触力が設定値ｆｓ未満であるときはウォークイン動作の起動速度及び復帰速度を低速にしている。 On the other hand, in this embodiment, as shown in steps S60 to S62 of FIG. 8, the magnitude of the force when the operator H (FIGS. 5A and 5B) touches the touch switch 33. The speed of the walk-in operation is adjusted depending on whether is greater than or less than the set value fs. Specifically, when the contact force with respect to the touch switch 33 is greater than or equal to the set value fs, the start-up speed and return speed of the walk-in operation are increased, and when the contact force with respect to the touch switch 33 is less than the set value fs, the walk-in operation is performed. The startup speed and return speed of operation are slow.
　この実施形態によれば、タッチスイッチ３３に触れている時間に関係なく、接触力だけによってウォークイン動作の速度を調節できるので、操作の仕方がより一層直感的になって操作し易くなった。なお、本実施形態を実現するにあたっては、接触力の大小を検知できる方式の感圧センサがタッチスイッチ３３として用いられる。 According to this embodiment, since the speed of the walk-in operation can be adjusted only by the contact force regardless of the time during which the touch switch 33 is touched, the operation method becomes more intuitive and easy to operate. In realizing the present embodiment, a pressure-sensitive sensor that can detect the magnitude of the contact force is used as the touch switch 33.
