ヘッドレスト回動機構50は、第3動作機構に相当し、着座位置にあるヘッドレスト30が前方に倒れた倒れ位置に位置するように、ピラー33を前方に回動させてヘッドレスト30を前方に倒す機構である。このヘッドレスト回動機構50は、不図示の樹脂カバーに覆われた状態でシートバックフレーム21の前側上部に固定されている。
ケーシング51は、ヘッドレスト回動機構50の筐体をなし、本実施形態では略矩形状の金属プレートを重ね合せて構成されており、その内部にはロック部材53やスライド部材54が収容されている。また、このケーシング51は、シートバックフレーム21に取り付けられており、シートバックフレーム21の幅方向に沿って長くなっており、その上部にてピラー33を回動可能に支持している。付勢バネ52は、ピラー33を前方に付勢する付勢部材の一例であり、ケーシング51の裏面(後面)側に設けられている。
一方、スライド部材54のスライド移動によってロック部材53が係合位置から解除位置へ揺動すると、ロック部材53とピラー側係合部33cとの係合が解除され、付勢バネ52の付勢力によりピラー33が前方に回動し、これに伴ってヘッドレスト30が前方に倒れるようになる。これら一連の動作が、ヘッドレスト30を前方に倒伏させるための動作であり、第3動作に相当する。
シートクッション跳ね上げ機構60は、跳ね上げ機構の一例であって第1動作機構に相当し、乗員による車両用シートS1の収納操作が受け付けられると、車両用シートS1を収納するための開始動作としてシートクッション10を跳ね上げ位置に向けて跳ね上げる動作を行うものである。このシートクッション跳ね上げ機構60は、不図示の樹脂カバーで覆われており、シートクッション10が着座位置に位置する際にはシートクッション10の下方位置に位置するように車体フロア2上に設置されている。
一方で、ロック片102を引張ってロック片102を揺動させることにより、ストライカ105とロック片102との係合が解除されると、渦巻きバネ128の付勢力により、リンク121が前方に回動する。この結果、シートクッション10が跳ね上げ位置に向けて跳ね上がるようになる。これらの一連の動作が、シートクッション10を跳ね上げるための一連の動作であり、第1動作に相当する。
次に、シートバック倒伏機構70について説明する。
シートバック倒伏機構70は、第2動作機構の一例であり、図12に示すシートバック支持ユニット90に回動可能に支持されたシートバック20を前方に倒れるように回動させる機構である。このシートバック倒伏機構70は、構成要素として、図12に示す付勢バネ71と、図13に示すロック機構72と、を有する。
なお、このロック片73は、不図示の捻りバネにより、その回動方向において係合可能位置に向かう向きに付勢されている。一方で、捻りバネの付勢力に抗してロック片73を係合可能位置から係合不能位置に向かう向きに回動させれば、ロック片73とストライカ74との係合状態を解除することが可能になる。
次に、アレンジユニット80について説明する。
アレンジユニット80は、駆動機構に相当し、車両用シートS1を収納する際に、シートクッション10の跳ね上げ動作に、シートバック20の前方への倒れ動作及びヘッドレスト30の前方への倒伏動作を連動させるための機構である。
なお、上記の設定角度は、任意に設定することが可能であり、例えば、第4ケーブルC4のケーブル長、凸部84bの形状及び倒れ角度検出機構130の設置位置等を調整することによって設定することが可能である。
通常時(車両用シートS1の姿勢が着座姿勢にある時)には、図15Aに示すように、第1回動部材83、第2回動部材84及び第3回動部材85は、それぞれ、第1コイルバネ88a、第2コイルバネ88b及び第3コイルバネ88cのうち、対応するコイルバネにより付勢されて初期位置に位置している。
以上の結果、シートバック倒伏機構70が作動して、ストライカ74とシートバック20との係合が解除されるようになる。
以上のような事情により、本実施形態では、シートバックフレーム21の上端及び下端の中間位置にアレンジユニット80を取り付けて、アレンジユニット80の作動安定性の向上を図っている。
アレンジユニット80から伸出したケーブルCのうち、シートクッション跳ね上げ機構60のリンク121に繋がれた第1ケーブルC1は、図5に示すように、アレンジユニット80のケーシング81の下部から伸出し、シートバックフレーム21の幅方向においてパンフレーム22の略中央部を通るように配索されている。
これまでに説明してきた通り、本実施形態に係る車両用シートS1は、解除機構200の他、ストライカ74との係合が解除された状態のシートバック20をストライカ74と係合可能な状態に復帰させるための復帰動作を行う復帰機構210を有している。そして、復帰機構210は、前方に倒れたシートバック20の倒れ角度に応じて、復帰動作を行うように構成されている。特に、本実施形態では、上記の倒れ角度が予め設定された設定角度に達した時点で、復帰動作が行われる。これにより、ストライカ74とシートバック20との係合の解除、及び、ストライカ74とシートバック20との再係合を適宜実行可能とし、操作性に優れた車両用シートS1が実現されることになる。
このような構成により、本実施形態では、第2回動部材84と係合ピン86との係合状態という機械的構成を調整することで、第2回動部材84の位置を制御することが可能になる。この結果、比較的簡易な構成によって、ストライカ74とシートバック20との係合が解除された状態と、ストライカ74とシートバック20とが再び係合可能となった状態との切り替えが可能になる。
そして、倒れ角度検出機構130の引張り力は、シートバック20の倒れ角度が設定角度に達した時点で、係合ピン86と凸部84bとの係止力を上回り、これにより、係合ピン86が凸部84bを乗り越えるようになる。
このような構成により、本実施形態では、第2回動部材84と係合ピン86との係合状態を、比較的簡易な構成により切り替えることが可能になる。また、凸部84bの形状を調整することにより、係合ピン86が凸部84bを乗り越える時点を調整することが可能になる。
上記の実施形態では、本発明の乗物用シートとして車両用シートS1を一例に挙げて説明した。しかし、上記の実施形態は、本発明の理解を容易にするためのものであり、本発明を限定するものではない。本発明は、その趣旨を逸脱することなく、変更、改良され得ると共に、本発明にはその等価物が含まれることはもちろんである。また、上述した材質や形状等は本発明の効果を発揮させるための一例に過ぎず、本発明を限定するものではない。
さらに、ヘッドレスト回動機構50とアレンジユニット80とが、ケーシングを共有する(つまり、ヘッドレスト回動機構50のケーシング51とアレンジユニット80のケーシング81とが一体化されている)構成であってもよい。
