Description
先ず、第1の発明は、着座部となるシートクッションの前部に設定されたチルト部をシートクッションの本体部に対して高さ方向に移動させることのできるフロントチルト機構を備えた車両用シートである。シートクッションの本体部には、フロントチルト機構の動力伝達部を構成する小ギアと小ギアよりも回転半径の大きい大ギアとが互いに噛合した状態で設けられている。チルト部は、大ギアが小ギアからの動力伝達を受けて高さ方向に回転する動きによって基準位置から高さ方向の双方向に移動操作されるようになっている。大ギアと小ギアとは、互いの回転中心が高さ方向にずれた配置関係となっている。
この第2の発明によれば、チルト部を大ギアの噛合部とは反対側に延びる腕部に連結することにより、大ギアの高さ方向の移動量が抑えられていても、大ギアの高さ方向の形状を増大させることなく、チルト部を高さ方向に大きく移動操作することができる。
この第3の発明によれば、チルト部は、そのシートクッションの前部において着座荷重を受け止める部位が、その回転中心位置から前方側に遠く離れた位置に配設されていることにより、その回転移動に伴う傾き姿勢の変化量が少なくなる。したがって、安定した着座感を保ったまま、チルト部の高さ方向の移動を行うことができる。

- 着座部となるシートクッションの前部に設定されたチルト部を該シートクッションの本体部に対して高さ方向に移動させることのできるフロントチルト機構を備えた車両用シートであって、
前記シートクッションの本体部には前記フロントチルト機構の動力伝達部を構成する小ギアと該小ギアよりも回転半径の大きい大ギアとが互いに噛合した状態で設けられており、前記チルト部は前記大ギアが前記小ギアからの動力伝達を受けて高さ方向に回転する動きによって基準位置から高さ方向の双方向に移動操作されるようになっており、前記大ギアと前記小ギアとは互いの回転中心が高さ方向にずれた配置関係となっており、
前記チルト部は前記大ギアの回転中心から前記小ギアとの噛合部とは反対側となる前方側に延びる腕部に連結されて前記シートクッションの前部において着座荷重を受け止める構成とされており、かつ、その後部が前記シートクッションの本体部に高さ方向に回転可能となるように軸支連結された構成とされており、前記チルト部の軸支連結された回転中心位置は前記小ギアの回転中心を間に挟んで前記大ギアの腕部から遠ざかる後方側の位置に設定されており、
前記チルト部と前記大ギアから延びる前記腕部との連結部の位置が、前記チルト部の前側の先端部と、前記チルト部の後部と前記シートクッションの本体部との連結部と、の間の位置に設定されていることを特徴とする車両用シート。
