Abstract
Description
このため、折り畳んだシートの高さをフロアに対して低く抑えることが難しい。
具体的には、車両用シート装置は、フロアの下方にロアフロアを設けることにより、フロアおよびロアフロアが壁部で連結され、フロアおよび壁部にスライドレールが設けられている。よって、壁部に設けられたスライドレール(以下、鉛直レールという)は上下方向に延出されている。
このため、格納モードに折り畳んだシートを車体前方に移動させて利便性を高めるシートの実用化が望まれていた。
図1、図2に示すように、車両10は、車両10の床部を形成する車体フロア11と、車体フロア11に設けられた車両用シート装置20とを備えている。
車両用シート装置20は、車体フロア11の後部に設けられた最後部のシートである。
低段フロア12は、車体前方に収納位置13を有する。収納位置13は、車両用シート装置20のシートバック61が前倒しされ、格納モード(図11参照)に折り畳まれた車両用シート装置20を収納する位置である。
高段フロア15は、低段フロア12に対して高さ寸法H1だけ高い位置に配置されている。
左シート25は、左スライドレール22を介して車体フロア11に車両前後方向にスライド移動可能に支持されている。
また、右シート24および左シート25は略左右対称の部材であり、以下右シート24について詳説して左シート25の説明を省略する。
内側レール28および外側レール29は、車幅方向に所定間隔をおいて互いに平行に車体前後方向に向けて延出されている。
内側レール28および外側レール29は、略左右対称の部材である。
可動ベース31は、内側レール28および外側レール29にスライド移動可能に支持された可動部32と、可動部32に設けられたシートバック支持部33と、可動部32に設けられたリンク支持部34とを備えている。
内側バック支持部41および外側バック支持部42(すなわち、シートバック支持部33)にバック支持軸44(図2参照)を介して車両用シート装置20のシートバック61が車体前後方向に回転可能に支持されている。
リンク支持部34が低段フロア12に対して非接触状態に配置されることにより、可動ベース31を固定レール27に沿って車体前後方向に円滑にスライド移動させることができる。
開口部53は、嵌合部52の上方に上向きで、かつ、脚連結部84の外径D1より僅かに小さく形成されている。
また、係止部51の嵌合部52から脚連結部84を外す際には、開口部53を脚連結部84で押し開け、押し開けた開口部53から脚連結部84を嵌合部52の外側に容易に外すことができる。
右シート24は、シートバック支持部33にバック支持軸44を介して車体前後方向に回転可能に設けられたシートバック61と、シートバック61に内外のクッション支持軸67(内クッション支持軸は図示せず)を介して回転可能に支持されたシートクッション69と、シートクッション69を係止部51に車体前後方向に回転可能に支持する連結リンク81とを備えている。
この状態において、シートバック支持部33に外側バックブラケット64および内側バックブラケット63がバック支持軸44で回転可能に支持される。すなわち、シートバック61は、シートバック支持部33(すなわち、可動ベース31)にバック支持軸44を介して車体前後方向に回転可能に設けられている。
よってバック支持軸44を高段フロア15に対して比較的低い位置P1に配置できる。これにより、右シート24が折り畳まれた格納モードにおいて、格納モードに折り畳まれた右シート24の高さH3(図11参照)を低く抑えることができる。
よって、シートクッション69が、内側クッションブラケット72の後部72bおよび外側クッションブラケット73の後部73b(具体的には、内外側のクッション支持軸67)を支点にしてシートバック61に車体前後方向へ回転可能に設けられている。
よって、例えば、右シート24が着座モード(図6に示す状態)に配置された状態で、シートバック61をバック支持軸44を中心にして車体前方に向けて前倒しすることにより、シートバック61でシートクッション69が車体前方に向けて押し出される。
連結リンク81は、上端部82aが内側リンクブラケット78に支持ピン86を介して車体前後方向に回転可能に支持された内側脚部82と、上端部83aが外側リンクブラケット79に支持ピン87を介して車体前後方向に回転可能に支持された外側脚部83と、内側脚部82の下端部82bおよび外側脚部83の下端部83bを連結する脚連結部(下端部)84とを有する。
よって、連結リンク81は、内側リンクブラケット78および外側リンクブラケット79に各支持ピン86,87を介して車体前後方向に回転可能に支持されている。
よって、連結リンク81は、シートクッション69の前部69aに車体前後方向に回転可能に支持されている。
ここで、脚連結部84を係止部51の嵌合部52に嵌合する際には、開口部53を脚連結部84で押し開け、押し開けた開口部53から脚連結部84を嵌合部52に容易に嵌合できる。
嵌合部52に脚連結部84が嵌合されることにより、脚連結部84が嵌合部52に車体前後方向に回転可能に支持される。
すなわち、脚連結部84(連結リンク81)は、係止部51によって車体前後方向に回転可能に支持され、かつ、係止部51から着脱可能に支持される。
また、脚連結部84は、係止部51に着脱自在に支持されている。よって、脚連結部84を係止部51から取り外すことにより、シートクッション69をシートバック61まで跳ね上げることができる(図8(b)参照)。
さらに、シートクッション69の前部69aに連結リンク81が車体前後方向に回転可能に支持されている。
よって、係止部51の嵌合部52に脚連結部84が嵌合された状態において、シートクッション69の前部69aが連結リンク81により車体前後方向に移動可能に支持されている。
これにより、右シート24を格納モード(図10(b)参照)に折り畳む際に、シートクッション69をシートバック61で車体前方に向けて円滑に移動させることができる。
図7(a)に示すように、右シート24が着座モードに配置されることにより、シートクッション69が着座位置P2に配置される。
右シート24が着座モードに配置された状態で、シートバック61がシートバック支持部33(図3参照)およびバック支持軸44を介してベース本体36に支持されている。さらに、シートクッション69が内外のクッション支持軸67を介してシートバック61に支持されるとともに連結リンク81を介して係止部51に支持されている。
すなわち、右シート24(シートバック61およびシートクッション69)が可動ベース31に支持されている。
さらに、着座モードの右シート24を可動ベース31とともに、固定レール27に沿って車体後方向(矢印C方向)にスライド移動することができる。
図8(a)に示すように、右シート24が着座モードに配置された状態で、シートクッション69を内外のクッション支持軸67を軸にして上方に矢印Dの如く持ち上げる。シートクッション69を持ち上げることにより連結リンク81の脚連結部84を係止部51から取り外すことができる。
ここで、連結リンク81がシートクッション69の底部69bに係止部材(図示せず)で固定される。
すなわち、シートバック61およびシートクッション69が可動ベース31に支持される。
図10(a)に示すように、右シート24が着座モードに配置された状態で、シートバック61をバック支持軸44を中心にして車体前方に向けて矢印Hの如く前倒しする。
シートバック61を前倒しすることにより、シートバック61(具体的には、内外のクッション支持軸67)でシートクッション69が車体前方に向けて矢印Iの如く押し出される。
よって、係止部51の嵌合部52に嵌合された脚連結部84を中心にして連結リンク81が車体前方に向けて矢印Jの如く回転する。連結リンク81が車体前方に向けて回転することにより、シートクッション69を車体前方で、かつ下方に向けて矢印Kの如く円滑に移動させることができる。
同時に、連結リンク81がシートクッション69の底部69b側に折り畳まれる。
このように、シートバック61がシートクッション69の上に重ね合わされることにより、右シート24が格納モード(ダイブダウンモード)に折り畳まれる。
すなわち、右シート24(シートバック61およびシートクッション69)が可動ベース31に支持されている。
このように、格納モードに折り畳んだ右シート24を収納位置13までスライド移動することにより右シート24の利便性を高めることができる。また、収納位置13の右シート24を用途に応じて固定レール27に沿って車体後方向にスライド移動することができる。
例えば、前記実施例では、車両用シート装置20を車体フロア11の後部に設けた最後部のシートとして説明したが、これに限るものではなく、車体フロア11の前部に設けたドライバシートやパッセンジャシートなどの他のシートに適用することも可能である。
