この発明は、シートクッションやシートバックの両脇部分に配置したサイドサポート、およびシート座面の傾きを電動で作動させるシート制御装置に関する。   The present invention relates to a side support disposed on both sides of a seat cushion and a seat back, and a seat control device that electrically operates the inclination of a seat seating surface.

従来、サイドサポートは、シートクッションまたはシートバックから乗員の腰の脇に向けて夫々突出状態でシートに固定されているものが知られていた。従来のシートにおいて、サイドサポートはシートクッションまたはシートバックから乗員の腰の脇に向けて夫々突出状態でシートに固定されているため、乗員が車両から降りる際に腰の横方向への移動が拘束されていることによって車両から降りずらく、また、乗員がシートに座る際にもシートクッションやシートバックから突出しているサイドサポートに腰部分が引っ掛かって座りずらいという問題点があり、前記の問題点を解決することが課題となっていた。   Conventionally, it has been known that the side support is fixed to the seat in a protruding state from the seat cushion or the seat back toward the side of the occupant's waist. In conventional seats, the side support is fixed to the seat in a protruding state from the seat cushion or seat back to the side of the occupant's waist, so that the lateral movement of the waist is restrained when the occupant gets off the vehicle. It is difficult to get off from the vehicle, and even when the occupant sits on the seat, there is a problem that the waist part is caught by the side support protruding from the seat cushion or the seat back, and it is difficult to sit down. It was a problem to solve.

この問題を解決するため、例えば、特許文献１（特開平７−１１１９２９号公報）に示された電動サイドサポート制御装置では、乗車時や降車時に邪魔にならない電動サイドサポート制御装置を提供していた。具体的には、乗員が降車する状態になると、サイドサポートを下げ、乗員が乗車して車両が走行するとサイドサポートを上げる電動サイドサポート制御装置としていた。
特開平７−１１１９２９号 In order to solve this problem, for example, in the electric side support control device disclosed in Patent Document 1 (Japanese Patent Application Laid-Open No. 7-111929), an electric side support control device that does not get in the way when getting on or getting off has been provided. Specifically, the electric side support control device is configured to lower the side support when the occupant gets off and raise the side support when the occupant gets on and the vehicle travels.
Japanese Patent Application Laid-Open No. 7-11129

ところが、前記した特許文献１による電動サイドサポート制御装置では、スポーツタイプのシートの場合、運転時のホールド性を高めるため体を包みこむようにサイドサポートとともに大腿部をホールドする部分も設けられ、このホールド部分が乗降性の阻害要因となっていた。   However, in the electric side support control device according to Patent Document 1 described above, in the case of a sports-type seat, a portion for holding the thigh with the side support so as to wrap the body is provided in order to improve holdability during driving, and this hold portion Was an obstacle to getting on and off.

本発明は、前記した従来技術の抱えた課題を解決するために成されたものであり、搭乗者のシートのホールド性を高めるための構造（サポート部）を乗降時に制御すると共に、シート全体の制御も行うことにより快適な乗降性を提供できるシート装置とすることを技術課題とした。   The present invention has been made to solve the above-described problems of the prior art, and controls the structure (support portion) for improving the holdability of the passenger's seat at the time of getting on and off, It was a technical problem to provide a seat device that can provide comfortable getting on and off by performing control.

上記課題を解決するために講じた技術的手段は、車両床面に配設されたシート座面と、シート座面に回動自在に支持されたシートバックと、シート座面を車両床面に対し傾動可能に支持する傾動機構と、シート座面に設けられたレッグサポートと、シートバックに設けられたサイドサポート、および搭乗者の乗降を検知する乗降検知部を有するシート装置において、搭乗者の乗降が乗降検知部により検出されたとき、傾動機構、サイドサポート、レッグサポートが車両のドアの方向に向かって傾動制御されるシート装置としたことである。   Technical measures taken in order to solve the above-described problems include a seat seat surface disposed on a vehicle floor surface, a seat back rotatably supported on the seat seat surface, and a seat seat surface on the vehicle floor surface. In a seat device having a tilting mechanism that supports tilting, a leg support provided on a seat seat surface, a side support provided on a seat back, and a boarding / alighting detecting unit that detects boarding / alighting of a passenger, Is detected by the boarding / alighting detection unit, the tilting mechanism, the side support, and the leg support are configured as a seat device that is tilt-controlled toward the door of the vehicle.

上記技術手段を講じたことにより、シート各部が乗降時に際して動作し全体としてフラットになるため、搭乗者の体と干渉することもなく、また搭乗者の乗降時の体重移動も円滑に行うことができ、結果として乗降性を向上することができるようになった。   By taking the above technical measures, each part of the seat operates at the time of getting on and off and becomes flat as a whole, so that it does not interfere with the passenger's body and can smoothly move the weight of the passenger when getting on and off. As a result, it became possible to improve boarding / exiting performance.

本発明の技術思想を適用した実施例について、車両用のシートおよびその制御装置を一例にして説明する。   An embodiment to which the technical idea of the present invention is applied will be described by taking a vehicle seat and its control device as an example.

図１は本発明を適用可能なシート装置を示す。シート装置１０は、シート座面１１とシートバック１２を備え、シートバック１２はシートリクライナー機構を介してシート座面１１対して回動自在に支持されている。   FIG. 1 shows a sheet apparatus to which the present invention can be applied. The seat device 10 includes a seat seat surface 11 and a seat back 12, and the seat back 12 is rotatably supported with respect to the seat seat surface 11 via a seat recliner mechanism.

シートバック１２は着座者の姿勢を安定支持させるため、両側部にサイドサポート１３ａ、１３ｂが設けられている。サイドサポート１３ａ、１３ｂは周知の通り正面視左右方向に開閉して着座者の体型に適応可能に動作する。なお、サイドサポート１３ａ、１３ｂはシートバック１２内に収容された、駆動モータ（図示略）によりその動きと動作が制御されている。シート座面１１はシートバック１２のサイドサポート１３ａ、１３ｂと同様に、着座者の姿勢を安定させるため、両側部にレッグサポート１４ａ、１４ｂが設けられている。レッグサポート１４ａ、１４ｂは周知の通り正面視左右方向に開閉し着座者の体型に適応可能に動作する。なお、レッグサポート１４ａ、１４ｂはシート座面１１内に収容された、駆動モータ（図示略）によりその動きと動作が制御されている。   The seat back 12 is provided with side supports 13a and 13b on both sides in order to stably support the posture of the seated person. As is well known, the side supports 13a and 13b open and close in the left-right direction when viewed from the front and operate so as to be adaptable to the body shape of the seated person. The side supports 13a and 13b are controlled in movement and operation by a drive motor (not shown) housed in the seat back 12. Similarly to the side supports 13a and 13b of the seat back 12, the seat seat surface 11 is provided with leg supports 14a and 14b on both sides in order to stabilize the posture of the seated person. As is well known, the leg supports 14a, 14b open and close in the left-right direction when viewed from the front and operate so as to be adaptable to the body shape of the seated person. The movement and operation of the leg supports 14a and 14b are controlled by a drive motor (not shown) housed in the seat seat surface 11.

シート１０は車両の前後にスライド可能となるよう、スライド機構１５を介して床面に固定されている。スライド機構１５は車両側に固定されるロアレールとシート側に固定されるアッパレールを有する。シート１０は、更に、図１の矢印で示した方向に沿い床面に対して左右に傾動するように、アッパレールとシート座面１１との間に傾動機構（図示略）が配されている。左右の傾動機構は独立して動作することができるようになっている。なお、傾動機構はシート座面１１内に収容された、駆動モータ（図示略）によりその動きと動作が制御されている。   The seat 10 is fixed to the floor surface via a slide mechanism 15 so as to be slidable forward and backward of the vehicle. The slide mechanism 15 has a lower rail fixed to the vehicle side and an upper rail fixed to the seat side. The seat 10 is further provided with a tilting mechanism (not shown) between the upper rail and the seat seat surface 11 so as to tilt to the left and right with respect to the floor surface along the direction indicated by the arrow in FIG. The left and right tilt mechanisms can operate independently. The movement and operation of the tilting mechanism are controlled by a drive motor (not shown) housed in the seat seat surface 11.

スライド機構１５のアッパレールとロアレールとの間には、着座者の体重を検知可能なセンサが配設され、着座者の有無とその重量が実測できるようになっている。   A sensor capable of detecting the weight of the seated person is disposed between the upper rail and the lower rail of the slide mechanism 15 so that the presence / absence of the seated person and its weight can be measured.

以下、本発明を用いた電動シート制御装置の制御について説明する。なお、制御装置にはスマートエントリーシステムを備えた車両を一例として、同システムとの強調制御を前提に説明する。   Hereinafter, control of the electric seat control apparatus using the present invention will be described. The control device will be described on the premise of emphasis control with the system as an example of a vehicle equipped with a smart entry system.

先ずスマートキーがステップＳ１にて室外に有る場合、スマートキーを保持した搭乗者（着座者）が車両から所定距離内にあるとシステムは認証を行い、ドアロックはアンロック待機状態となる。次に搭乗者がアウトサイドハンドル（Ｏ／Ｈ）を操作すると車両に「乗る」意思有りと判断し、ステップＳ２において制御装置に対しドア開の信号を出力する。一方、ステップＳ３にてスマートキーを持つ搭乗者が車両内に存在し、インサイドハンドル（Ｉ／Ｈ）を操作すると車両から「降りる」意思有りと判断し、ステップＳ４において制御装置に対しドア開の信号を出力する。なお、ステップ５ではシート位置調節操作スイッチＳ５から制御装置の駆動制御部Ｓ６に出力され、シートの位置が調節できるようになっている。制御装置は前述の駆動制御部Ｓ６、シート位置検出部Ｓ７を備えシート装置の駆動モータに駆動制御信号が出力される。   First, when the smart key is outside the room in step S1, the system performs authentication if the passenger (seat) holding the smart key is within a predetermined distance from the vehicle, and the door lock enters the unlock standby state. Next, when the passenger operates the outside handle (O / H), it is determined that there is an intention to “get on” the vehicle, and in step S2, a door opening signal is output to the control device. On the other hand, if a passenger with a smart key is present in the vehicle in step S3 and the inside handle (I / H) is operated, it is determined that there is an intention to “get off” from the vehicle, and the door is opened to the control device in step S4. Output a signal. In step 5, the sheet position adjustment operation switch S5 outputs the control signal to the drive control unit S6 of the control device so that the position of the sheet can be adjusted. The control device includes the aforementioned drive control unit S6 and sheet position detection unit S7, and a drive control signal is output to the drive motor of the sheet device.

ステップＳ２，Ｓ４（乗降検知部）にて「ドア開」信号が出力されると、この信号は駆動制御部Ｓ６、シート位置検出部Ｓ７に送出される。制御装置の後段には体重検知装置を有するシート装置が配され、制御装置からの出力信号は体重検知装置Ｓ８が授受する。体重検知装置Ｓ８では、シート座面１１上への搭乗者の有無が検出され、搭乗者が車両内に存在するか否かを検知する。   When the “door open” signal is output in steps S2 and S4 (alighting / alighting detection unit), this signal is sent to the drive control unit S6 and the seat position detection unit S7. A seat device having a weight detection device is arranged at the subsequent stage of the control device, and an output signal from the control device is transmitted and received by the weight detection device S8. In the weight detection device S8, the presence or absence of a passenger on the seat seat surface 11 is detected, and it is detected whether or not the passenger is present in the vehicle.

体重検知装置Ｓ８からは、左右のリンク機構の駆動装置Ｓ９、Ｓ１０（傾動機構、サイドサポート、レッグサポートを含む）への駆動制御信号が送出され、各部の電動モータが制御される。   From the body weight detection device S8, drive control signals are sent to the drive devices S9 and S10 (including the tilting mechanism, side support, and leg support) of the left and right link mechanisms, and the electric motors of the respective parts are controlled.

リンク機構の駆動装置Ｓ９、Ｓ１０は、例えば、運転席側に搭乗する場合、ドア開信号により右側の傾動装置をドア側に向かってシート座面１１が傾斜するように駆動する。同時に右側のサイドサポート１３ｂ、レッグサポート１４ｂはドア側に向かって開くように駆動される。以上動作により、シート装置は搭乗者を迎え入れるように動作して搭乗性が向上する。運転席側から降りる場合、ドア開信号により右側の傾動装置をドア側に向かってシート座面１１が傾斜するように駆動する。同時に右側のサイドサポート１３ｂ、レッグサポート１４ｂはドア側に向かって開くように駆動される。以上動作により、シート装置は搭乗者が容易にシートから降りられるように動作して降車性が向上する。   For example, when driving on the driver's seat side, the link mechanism driving devices S9 and S10 drive the right tilting device by the door opening signal so that the seat surface 11 is tilted toward the door side. At the same time, the right side support 13b and leg support 14b are driven to open toward the door. By the above operation, the seat device operates so as to welcome the occupant, and the riding performance is improved. When getting off from the driver's seat side, the right tilting device is driven by the door open signal so that the seat seat surface 11 tilts toward the door side. At the same time, the right side support 13b and leg support 14b are driven to open toward the door. By the above operation, the seat device operates so that the passenger can easily get off the seat, and the dismounting property is improved.

以上、運転席側のシート装置を一例に作動説明したが、助手席側も同様に機能させることができる。この場合、傾動機構、サイドサポート、レッグサポートは左側が駆動されるよう制御装置から信号が出力される。   The operation of the driver seat side seat device has been described above as an example, but the passenger seat side can also function in the same manner. In this case, a signal is output from the control device so that the left side of the tilt mechanism, the side support, and the leg support is driven.
