Description
本発明の目的は、上記問題点を解消し、シートバックをどちらの方向に作動させても不快感が生じないシート駆動装置を提供することである。
また、車両が障害物等に異常に接近したときのような緊急事態が発生したことが車両状態検出ECU100から伝えられると、乗員を適正な着座姿勢で拘束できるようにシートバックを所定位置に高速で作動させる緊急駆動モードも含まれている。なお、緊急駆動モード時に高速でシートバック4を所定位置に作動させることができるような大容量の電動モータMを採用している場合、従来技術の制御では、低負荷予備動作時のシートバック4の作動速度も高速となるためその時の不快感が顕著となりやすい。従って、高速でシートバック4を作動させる緊急駆動モードを備えた車両のシート駆動装置において本発明は特に有効となる。
まず、作動角調整スイッチ7が操作されているかどうかチェックされる(#01)。操作されていない場合(#01No分岐)、M-フラグに「0」をセットする(#02)。さらに、電動モータMが駆動している場合には、電動モータを停止させる(#03)。

7 角度調整スイッチ
8 コントロールユニット
53 楔部材
54 軸部材

Claims (3)
- 弾性体の付勢力を付与された楔部材を用いて保持することで遊動を阻止するとともにこの楔部材を変位させることで動力を伝達する噛み合い式伝動機構と、前記噛み合い式伝動機構を介して座席のシートバックを作動させるアクチュエータと、前記アクチュエータの駆動を制御するコントロールユニットとを備え、
前記コントロールユニットは、実行されたシートバック作動の方向を記憶する作動方向記憶部と、前記シートバックを所定速度で作動させるように前記アクチュエータを駆動するシート作動モードと、前記アクチュエータを前記シート作動モード時よりさらに遅い速度で駆動する微速モードとを備えており、
前回のシートバック作動と逆の方向に作動する時には、前記シート作動モードでの前記アクチュエータの駆動に先立って、前記楔部材に対して前記噛み合い式伝動機構の保持解除のための負荷を与えるまで前記アクチュエータを微速モードで駆動するシート駆動装置。 - 前記微速モードでの駆動時間を設定するタイマーを備える請求項1に記載のシート駆動装置。
- 前記噛み合い式伝動機構は、内歯歯車と、前記内歯歯車より少ない歯数を有するとともに前記内歯歯車に対して噛み合いながら偏芯回転運動を行う外歯歯車と、前記アクチュエータの駆動力を前記楔部材に付与することで前記楔部材を回動変位させる軸部材とを有し、前記楔部材は前記弾性体によって前記内歯歯車と前記外歯歯車との偏芯量を増大する方向の付勢力を受けて前記内歯歯車と前記外歯歯車とを規制することにより前記内歯歯車と前記外歯歯車との噛み合い位置を保持している請求項1又は2に記載のシート駆動装置。
