本発明の一実施例を図面により説明すると、１は車両用シートであり、座席シート２および背凭シート３を有し、背凭シート３は座席シート２に対して水平状態を含む傾斜角度調節自在にリクライニング装置４を介して取付ける。
しかして、前記車両用シート１は、着座可能状態から座席シート２および背凭シート３が車体の床面５に対して縦方向（走行方に並行）となるように前後方向の横軸６中心に回動自在に構成し、所謂跳ね上げシート（跳ね上げ状態）と呼ばれる形態変化可能に構成し、前記座席シート２の反横軸６側には該座席シート２を支持する脚部８を設け、該脚部８と前記床面５との間には車両用シート１を着座状態に固定する固定装置１０を設ける。
【０００７】
固定装置１０は、車体側である床面５に設けたストライカ１１と、該ストライカ１１に係合固定するラッチ（図示省略）とからなるラッチ機構を、前後に２個配置して構成する。なお、前後側ラッチ機構１２、１３は前記ラッチとストライカ１１との固定状態を保持するラチェット等を有する任意の構成のものでよい。
しかして、前記前側ラッチ機構１２および後側ラッチ機構１３には、ラッチとストライカ１１との固定状態を解除する前後側オープンレバー１５、１６を夫々設け、前側オープンレバー１５と後側オープンレバー１６は一つの操作レバー１７により操作可能に構成し、操作レバー１７と前側オープンレバー１５および後側オープンレバー１６との間には操作伝達機構１８を設け、操作伝達機構１８は前側ラッチ機構１２および後側ラッチ機構１３の何れか一方の固定状態を解除した後に他方の固定状態を解除するように構成する。
【０００８】
２０は前側ラッチ機構１２の前側カバープレートであり、前側カバープレート２０より前記前側オープンレバー１５を後方に突出させ、前側オープンレバー１５は前後方向に移動自在に設けている。
前記前側オープンレバー１５の先端は中間伝達部材２１の下部に取付ける。中間伝達部材２１は上下方向のアーム形状に形成し、その上下中間部を中間伝達部材取付軸２２により脚部８の脚部フレーム２３に回動自在に取付ける。
中間伝達部材２１の上部には前記操作レバー１７の基部を取付け、操作レバー１７を前方に引くと、中間伝達部材２１が回転して前側オープンレバー１５を牽引し、前側ラッチ機構１２のラッチとストライカ１１の係合を開放する。
【０００９】
前記中間伝達部材２１には、ロッド２４の前端を取付け、ロッド２４の後端は後側オープンレバー１６に取付け、後側オープンレバー１６は軸２５により後側ラッチ機構１３の後側カバープレート２６に回動自在に取付ける。
この場合、ロッド２４の前端部は、前側オープンレバー１５に比し中間伝達部材取付軸２２に近い部分の中間伝達部材２１に取付け、中間伝達部材取付軸２２を中心とする円弧の半径を小にし、前側ラッチ機構１２と後側ラッチ機構１３とのラッチの開放時期をずらせている。なお、この構成においても、前側オープンレバー１５と後側オープンレバー１６のストロークの設定により、前側ラッチ機構１２および後側ラッチ機構１３のどちらを先行させて開放するかは任意に設定可能である。
【００１０】
３０は中間伝達部材２１を反開放方向に付勢するバネ、３１は中間伝達部材２１に設けた突起のガイド体、３２はガイド溝であり、ガイド体３１とガイド溝３２は中間伝達部材２１の回動を停止させるストッパを兼用する。３３は前側カバープレート２０および後側カバープレート２６に形成したストライカ進入溝である。
【００１１】
図４、図５は、第２実施例であり、前記中間伝達部材２１を下側アーム部３４と、上側アーム部３５とに分割形成し、下側アーム部３４に前記前側オープンレバー１５を、上側アーム部３５にロッド２４（後側オープンレバー１６）を夫々取付け、下側アーム部３４と上側アーム部３５の間に両者を一体回動させるように付勢する一体回動用バネ３６を設け、操作レバー１７を前方に引くと、下側アーム部３４と上側アーム部３５とが一体回動用バネ３６により一体回動し、これにより前側オープンレバー１５を牽引し、更に操作レバー１７を前方に引くと、一体回動用バネ３６の弾力に抗して上側アーム部３５を回動させてロッド２４を牽引して、後側オープンレバー１６を回動させる。
【００１２】
【作用】
以上の構成であり、着座可能状態の座席シート２および背凭シート３は、背凭シート３をリクライニング装置４により座席シート２に対して平らに倒し、次ぎに、脚部８に設けた固定装置１０の操作レバー１７を操作し、ラッチとストライカ１１との係合を開放すると、車両用シート１は床面５に対して移動自在となり、縦方向に跳ね上げ、この状態で任意の手段で固定する。
前記の場合、固定装置１０は車体側である床面５に設けたストライカ１１と、該ストライカ１１に係合固定するラッチ（図示省略）とからなるラッチ機構を、前後に２個配置して構成しているから、着座可能状態を強固に保持する。
【００１３】
この２個の前後側ラッチ機構１２、１３は、ラッチとストライカ１１との固定状態を解除する前後側オープンレバー１５、１６を夫々設けているが、前側オープンレバー１５と後側オープンレバー１６は一つの操作レバー１７により操作可能に構成しているから、操作レバー１７は、ワンモーションで２個の前後側ラッチ機構１２、１３のストライカ１１をフリー状態にして、操作性を低下させない。
操作レバー１７と、前側オープンレバー１５と後側オープンレバー１６との夫々間には操作伝達機構１８を設け、操作伝達機構１８は前側ラッチ機構１２および後側ラッチ機構１３の何れか一方の固定状態を解除した後に他方の固定状態を解除するように構成しているから、開放操作を確実にする。
【００１４】
前側ラッチ機構１２の前側オープンレバー１５は、脚部８に中間伝達部材取付軸２２により回動自在に設けた中間伝達部材２１に取付け、中間伝達部材２１に操作レバー１７の基部を取付けるとともに、後側オープンレバー１６を操作するロッド２４と前側オープンレバー１５は、何れか一方は何れか他方に比し中間伝達部材２１の回動中心（取付軸２２）に近い部分に取付け、軸間距離を相違させているから、前側ラッチ機構１２と後側ラッチ機構１３の夫々のラッチの開放時期を簡単な構成でずらせられる。
【００１５】
図４、図５の第２実施例では、中間伝達部材２１を下側アーム部３４と、上側アーム部３５とに分割形成し、下側アーム部３４に前側オープンレバー１５を、上側アーム部３５にロッド２４（後側オープンレバー１６）を夫々取付け、下側アーム部３４と上側アーム部３５の間に両者を一体回動させるように付勢する一体回動用バネ３６を設けているから、操作レバー１７を前方に引くと、下側アーム部３４と上側アーム部３５とが最初は一体回動用バネ３６により一体回動し、これにより前側オープンレバー１５を牽引し、更に操作レバー１７を前方に引くと、一体回動用バネ３６の弾力に抗して上側アーム部３５を回動させてロッド２４を牽引して、後側オープンレバー１６を回動させる。
なお、本願発明の要件ではないが、座席シート２に対して脚部８を折り畳み自在に構成して、車両用シート１を跳ね上げたとき、脚部８を座席シート２と略並行となるように折り畳む。
【００１６】
しかして、脚部８を座席シート２に対して交差方向に持ち上げ、この状態で、車両用シート１の跳ね上げの固定を解除して、横軸６中心に下方回動させると、固定装置１０の前側ラッチ機構１２および後側ラッチ機構１３の夫々の前側カバープレート２０および後側カバープレート２６に夫々形成したストライカ進入溝３３にストライカ１１が進入してラッチが係合し、車両用シート１の座席シート２を通常着座位置に固定し、次ぎに、リクライニング装置４により背凭シート３を起こすと、車両用シート１は通常着座状態となる。
【００１７】
【発明の効果】
本発明は、横方向の着座可能状態の座席シート２と該座席シート２に対して起立した背凭シート３からなり、前記座席シート２と背凭シート３を平らにしたまま横軸回動させて床面５に対して縦置きとなる跳ね上げ可能な車両用シート１において、車体側に固定のストライカ１１と、シート側に設けた前記ストライカ１１と係合するラッチを有するラッチ機構とを、夫々前後に２個配置し、２個の前後側ラッチ機構１２、１３は一つの操作レバー１７により操作可能に構成すると共に、前記２個の前側ラッチ機構１２と後側ラッチ機構１３のラッチを開放する前側オープンレバー１５と後側オープンレバー１６は、２個の前後側ラッチ機構１２、１３のうち、何れか一方の固定状態を解除した後に他方の固定状態を解除するようにした操作伝達機構１８を介して操作レバー１７に連結し、前記操作伝達機構１８は、中間伝達部材２１の中間部を中間伝達部材取付軸２２により回動自在に取付け、前記中間伝達部材２１の端部に前記操作レバー１７を取付け、前記後側オープンレバー１６と前側オープンレバー１５を、何れか一方は何れか他方に比し中間伝達部材２１の回動中心に近い部分であって、かつ、前記操作レバー１７の取付部分よりも回動中心に近い部分の中間伝達部材２１に、軸により夫々取付けた跳ね上げ車両用シートの固定装置としたものであるから、確実に固定状態を解除して、操作性を向上させる。
