Abstract

<P>PROBLEM TO BE SOLVED: To simplify the interlocking mechanisms of an open member 23 and a keep member 25. <P>SOLUTION: This walk-in locking mechanism comprises, on an upper rail 4 side, interlocking press-contact parts 32a and 43 moving a memory member 28 together with a lock lever, the open member 23, and the keep member 25 by bringing the locking spring 40 of the memory member 28 from a locked state to an unlocked state Q in the raised state of a seat back. In the fallen state of the seat back, the lock lever, the open member 23, and the keep member 25 are allowed to move apart from the memory member 28 according to the movement of an upper rail 4. Since the memory member 28 is not interlocked with the raised and fallen state of the seat back, when the initial position of a seat is re-adjusted in a normal unlocked state in which the lock lever is brought in the unlocked state at the initial position of the seat, it is only necessary to additionally install the interlocking press-contact parts 32a and 43 moving the memory member 28 interlockingly with the open member 23 and the keep member 25. <P>COPYRIGHT: (C)2004,JPO&NCIPI

Description

【0001】
【発明の属する技術分野】
本発明は、車両のシートトラックスライド装置において、シートを初期位置から移動させた後に再びシートを初期位置に自動的に戻すことができるメモリ付きウォークインロック機構に関するものである。
【0002】
【従来の技術】
従来、シートトラックスライド装置のメモリ付きウォークインロック機構は例えば下記特許文献1で開示されている。
【0003】
同特許文献1の図面に示すように、ロックレバー13とオープンレバー15とキープレバー22とがアッパレール5に支持されているとともに、メモリレバー8がオープンレバー15に組み付けられた状態でロアレール3に支持されている。アッパレール5をロアレール3に対し移動させると、ロックレバー13やオープンレバー15やキープレバー22も移動する同時に、メモリレバー8もアッパレール5の移動方向へオープンレバー15とともに移動する。
【0004】
シート4の初期位置でシートバック4aを起こした通常ロック状態では、オープンレバー15が回動してロックレバー13がロック状態になるとともに、メモリレバー8が係止解除状態になる。その場合、ハンドル12によりロックレバー13をロック解除状態にしてシート4の初期位置を再調節することができる。
【0005】
前記通常ロック状態でシートバック4aを倒してオープン状態にすると、オープンレバー15が回動してロックレバー13がロック解除状態になるとともに、メモリレバー8が係止状態になり、そのオープン状態がキープレバー22により保持される。
【0006】
前記オープン状態でシート4を初期位置から前方へ移動させたメモリ状態では、アッパレール5とともにロックレバー13やオープンレバー15やキープレバー22が移動してメモリレバー8から離れる。その場合、メモリレバー8はシート4の初期位置に残る。
【0007】
その後、前記メモリ状態でシート4を後方へ移動させて初期位置に戻すと、メモリレバー8によりキープレバー22による保持が解除されて前記通常ロック状態に戻る。
【0008】
【特許文献1】
特公平6−47353号公報
【0009】
【発明が解決しようとする課題】
上記特許文献1では、シートバック4aを起こしたり倒したりする動きにメモリレバー8が連動して係止解除状態となったり係止状態となったりする。そのため、オープンレバー15とキープレバー22とメモリレバー8との間の連動機構が原因になってメモリ付きウォークインロック機構の構造が複雑になる問題があった。
【0010】
この発明は、オープン部材(オープンレバー15に該当)とキープ部材(キープレバー22に該当)とメモリ部材(メモリレバー8に該当)との間の連動機構を改良して、メモリ付きウォークインロック機構の構造を簡単にすることを目的としている。
【0011】
【課題を解決するための手段及び発明の効果】
後記実施形態の図面(図1〜10)の符号を援用して本発明を説明する。
* 請求項1〜2の発明
請求項1の発明にかかるシートトラックスライド装置のメモリ付きウォークインロック機構は、下記のように構成されている。
【0012】
シートトラックスライド装置のメモリ付きウォークインロック機構は、車体のフロア(2)に固定されるロアレール(3)と、シート(5)に固定されるとともにロアレール(3)に対し移動可能に支持したアッパレール(4)と、ロアレール(3)に対するアッパレール(4)の移動を阻止するロック状態(R)と許容するロック解除状態(S)とを取り得るようにアッパレール(4)に対し移動可能に支持したロック部材(ロックレバー16)と、シ−ト(5)のシ−トバック(5a)を起こしたときロック部材(16)をロック状態(R)にするとともにシ−トバック(5a)を倒したときロック部材(16)をロック解除状態(S)にしてそのロック解除状態(S)を保持するようにアッパレール(4)側で移動可能に支持した作動部材(オープン部材23、キープ部材25)と、ロアレール(3)側でアッパレール(4)の移動方向(X)に沿って移動可能に支持したメモリ部材(28)とを備えている。このメモリ部材(28)は、凹凸関係で係止され、ロアレール(3)側に設けた係止部(係止凹部39)に対し係止状態(P)と係止解除状態(Q)とを取り得る係止部(係止ばね40)を有している。シ−トバック(5a)を倒した状態でロック部材(16)と作動部材(23,25)とがアッパレール(4)の移動に伴いメモリ部材(28)から離れるのを許容する。シ−トバック(5a)を起こした状態でアッパレール(4)の移動に伴いメモリ部材(28)の係止部(40)を係止状態(P)から係止解除状態(Q)にしてそのメモリ部材(28)をロック部材(16)及び作動部材(23,25)とともにアッパレール(4)の移動方向(X)へ移動させる連動押接部(32a,43)をアッパレール(4)側に設けている。
【0013】
ここに、「アッパレール(4)の移動に伴いメモリ部材(28)の係止部(40)を係止状態(P)から係止解除状態(Q)にして」とは、請求項4の発明のように解除押接部(42)により強制的に係止解除状態(Q)で保持してメモリ部材(28)の円滑な追従移動を許容すること以外に、アッパレール(4)の移動時にメモリ部材(28)の係止部(40)がその移動力により自然に係止状態(P)から係止解除状態(Q)になるようにしてメモリ部材(28)の追従移動を許容することも含む概念である。また、「係止状態(P)」と「係止解除状態(Q)」とはメモリ部材(28)の移動抵抗の程度の差により決まり、係止状態(P)での移動抵抗は係止解除状態(Q)での移動抵抗よりも大きくなるように設定され、係止状態(P)ではメモリ部材(28)が初期位置を確実に記憶し得るために各種力に対して不用意な移動が阻止される程度の抵抗を持つとともに、係止解除状態(Q)ではメモリ部材(28)が円滑に追従移動し得る程度の抵抗を持つことが必要である。
【0014】
請求項2の発明は請求項1の発明を前提として下記のように構成されている。
前記作動部材は、シ−ト(5)のシ−トバック(5a)を起こしたときロック部材(16)をロック状態(R)にするとともにシ−トバック(5a)を倒したときロック部材(16)をロック解除状態(S)にするようにアッパレール(4)側で移動可能に支持したオープン部材(23)と、シ−トバック(5a)を倒した状態でオープン部材(23)に係合してロック部材(16)及びオープン部材(23)の移動位置を保持する保持状態(K)を取り得るようにアッパレール(4)側で移動可能に支持したキープ部材(25)とを備えている。キープ部材(25)の保持状態(K)でアッパレール(4)の移動に伴いキープ部材(25)がメモリ部材(28)に当接してオープン部材(23)とロック部材(16)とをシ−トバック(5a)を起こした状態に戻す。
【0015】
請求項1〜2の発明では、シートバック(5a)を起こしたり倒したりする動きにメモリ部材(28)が連動しない。そのため、シート(5)の初期位置でロック部材(16)をロック解除状態(S)にした通常ロック解除状態においてシート(5)の初期位置を再調節する場合にメモリ部材(28)を作動部材(オープン部材23、キープ部材25)に連動して移動させるメモリ部材追従手段として、連動押接部(32a,43)を付設するだけでよく、作動部材(オープン部材23、キープ部材25)の連動機構を簡略化することができる。従って、メモリ付きウォークインロック機構の構造を簡単にすることができる。
【0016】
* 請求項3の発明
この発明は、請求項2の発明を前提として下記のように構成されている。
前記連動押接部(32a)は、シ−トバック(5a)を起こした状態でアッパレール(4)の移動方向(X)の両向き(XF,XB)のうち一方の向き(XF)へのアッパレール(4)の移動に伴いメモリ部材(28)をオープン部材(23)及びキープ部材(25)とともに一方の向き(XF)へ移動させるようにオープン部材(23)に設けられている。前記連動押接部(43)は、シ−トバック(5a)を起こした状態でアッパレール(4)の移動方向(X)の両向き(XF,XB)のうち他方の向き(XB)へのアッパレール(4)の移動に伴いメモリ部材(28)をオープン部材(23)及びキープ部材(25)とともに他方の向き(XB)へ移動させるようにアッパレール(4)に取着した押圧部材(27)に設けられている。
【0017】
この発明では、オープン部材(23)を連動押接部(32a)に兼用して前記メモリ部材追従手段の構造を簡略化することができる。従って、メモリ付きウォークインロック機構の構造をより一層簡単にすることができる。
【0018】
ただし、前記連動押接部(32a)をオープン部材(23)に設ける必要はなく、前記押圧部材(27)の連動押接部(43)と同様に、オープン部材(23)とは別に設けた押圧部材に設けてもよい。
【0019】
* 請求項4の発明
この発明は、請求項3の発明を前提として下記のように構成されている。
前記メモリ部材(28)が前記押圧部材(27)の連動押接部(43)と前記オープン部材(23)の連動押接部(32a)との間に位置する状態でこのメモリ部材(27)の係止部(40)を係止解除状態(Q)に保持する解除押接部(42)をアッパレール(4)に取着した。例えば、この解除押接部(42)は前記押圧部材(27)に設けられている。
【0020】
この発明では、シート(5)の初期位置を再調節するためにメモリ部材(28)を作動部材(オープン部材23、キープ部材25)に連動して移動させる場合、メモリ部材(27)の係止部(40)が係止解除状態(Q)にあるので、メモリ部材(27)の追従移動を円滑に行うことができる。
【0021】
* 請求項5の発明
この発明は、請求項4の発明を前提として下記のように構成されている。
前記ロアレール(3)側の係止部は、メモリ部材(28)の移動方向(前後方向X)に沿って並設された複数の係止凹部(39)である。前記メモリ部材(28)の係止部は、この係止凹部(39)に対し係脱し得る係止ばね(40)であって、弾性力により係入される係止状態(P)と、弾性力に抗して離脱される係止解除状態(Q)とを取り得る。例えば、この係止ばね(40)は片持ち梁状または両持ち梁状の板ばねである。
【0022】
この発明では、メモリ部材(28)を位置決めするとともにメモリ部材(28)の移動を許容するための係止手段を簡略化することができる。従って、メモリ付きウォークインロック機構の構造をより一層簡単にすることができる。また、メモリ部材(27)の係止ばね(40)がロアレール(3)側の各係止凹部(39)から離れた係止解除状態(Q)で、メモリ部材(27)が追従移動するので、係止ばね(40)が各係止凹部(39)に対し擦れる摩擦音の発生を防止することができる。
【0023】
【発明の実施の形態】
以下、本発明の一実施形態にかかるシートトラックスライド装置について図1〜10を参照して説明する。
【0024】
図2で概略的に示すように、シートトラック1として、車体のフロア2には図1に示す左右方向Y(車両の前進側と後退側とを結ぶ水平な前後方向Xに対し直交する水平方向)の両側でロアレール3が固定され、左右両側のアッパレール4がシート5に固定されて左右両ロアレール3に支持されている。
【0025】
図4,6,10に示すように、前記左右両ロアレール3内にはスライド溝6が前後方向Xに沿って形成されている。この左右両ロアレール3上でスライド溝6には上下方向Z(水平な前後方向Xに対し直交する鉛直方向)へ開放された開口6aが形成されている。この左右両ロアレール3の内側壁3aには複数のロック孔7(ロック部)が前後方向Xに沿って並設されている。
【0026】
前記左右両アッパレール4において、その下端部には左右両ロアレール3のスライド溝6に挿入される案内支持部8が形成され、前記シート5に固定される取付壁部9が案内支持部8から開口6aを通して上方へ突出している。この左右両アッパレール4は、スライド溝6において案内支持部8でガイド10上に載置され、左右両ロアレール3に対し前後方向Xへ移動可能に支持されている。
【0027】
前記左右両アッパレール4の取付壁部9の内側にはロックレバー回動支持機構Mが取り付けられている。左側のロアレール3及びアッパレール4と右側のロアレール3及びアッパレール4とは同一構造をなし、左右両ロックレバー回動支持機構Mはコ字形状のハンドル11により互いに連動するようになっている。この左右両アッパレール4及びシート5は左右両ロアレール3に対し前後方向Xへ移動する。図1には一方のロアレール3及びアッパレール4のみを図示する。
【0028】
前記ハンドル11は、左右両アッパレール4の取付壁部9の内側に対し回動可能に支持された左右両ハンドルレバー12と、この左右両ハンドルレバー12に連結されたコ字形状のハンドル棒13とを備えている。この左右両ハンドルレバー12は、前記ロックレバー回動支持機構Mに連動し得る押圧部14を有している。この押圧部14はねじりコイルばね(図示せず)の弾性力により上方へ付勢されている。このハンドル棒13をねじりコイルばね(図示せず)の弾性力に抗して上方へ持ち上げると、この左右両ハンドルレバー12が回動し、押圧部14が下方へ移動する。
【0029】
前記ロックレバー回動支持機構Mは、ロックブラケット15とロックレバー16(ロック部材)と棒状ばね17とを備えている。このロックブラケット15は、左右両ロアレール3の上方で左右両アッパレール4の取付壁部9の内側に取着され、左右両ロアレール3の各ロック孔7に対向し得る透孔18を有しているとともに、ロックレバー16を支持し得る前後両支持板部19を有している。このロックレバー16は、その前後両支持板部20でロックブラケット15の前後両支持板部19に対し回動可能に支持され、左右両ロアレール3の各ロック孔7に係脱されるロック爪21を有しているとともに、ハンドルレバー12の押圧部14に係合し得る連動部22を有している。棒状ばね17はロックブラケット15とロックレバー16とに掛止めされ、この棒状ばね17の弾性力によりロックレバー16が付勢されてロック状態Rになる。このロック状態Rでロックレバー16のロック爪21が左右両ロアレール3の各ロック孔7に係入される。このロック状態Rでロック位置11Rにあるハンドル11をねじりコイルばね(図示せず)の弾性力に抗して上方へ持ち上げてロック解除位置11Sにすると、ハンドルレバー12の押圧部14がロックレバー16の連動部22を下方へ押さえてロックレバー16が棒状ばね17の弾性力に抗して回動する。その回動に伴い、ロックレバー16のロック爪21が左右両アッパレール4の透孔8a、左右両ロアレール3のロック孔7及びロックブラケット15の透孔18から離脱してロック解除状態Sになる。
【0030】
図3,8に示すように、一方のアッパレール4の取付壁部9の外側には、オープン部材23が支軸24を中心に回動可能に支持されているとともに、このオープン部材23の前方でキープ部材25が支軸26を中心に回動可能に支持され、さらにこのキープ部材25の前方で押圧部材27が取着されている。また、前記左右両ロアレール3のうち一方のロアレール3の外側壁3bには、これらの部材23,25,27の下方でメモリ部材28がアッパレール4の移動方向(前後方向X)へ移動可能に支持されているとともに、係止部材29がこのメモリ部材28の移動方向(前後方向X)に沿って延びるように取着されている。
【0031】
前記オープン部材23においては、ねじりコイルばね30が巻装された支軸24から前側の係止レバー31と後側の押接レバー32とが延設されている。この係止レバー31には、前記シート5のシートバック5aに連結された連動ロッド33が連結されているとともに、前記ロックレバー16の連動部22に係合し得る連動ピン34(連動部)が取着されている。前記キープ部材25においては、ねじりコイルばね35が巻装された支軸26から前側の解除レバー36と後側の係止レバー37とが延設され、この係止レバー37と前記オープン部材23の係止レバー31とが前後両側で互いに隣接している。このオープン部材23とキープ部材25とは、それらの係止レバー31,37が互いに接近する回動向き(矢印向き)へねじりコイルばね30,35により付勢され、それらの係止レバー31,37には互いに係合し得る係止部31a,37aが形成されている。
【0032】
前記係止部材29においては、多数の係止凹部39が前記メモリ部材28の移動方向(前後方向X)に沿って並設されている。このメモリ部材28においては、片持ち梁状の係止ばね40(板ばね)が取着され、この係止ばね40の自由端部40aが各係止凹部39に向けて延設されている。前記押圧部材27においては、腕部41が前記キープ部材25の係止レバー37及びオープン部材23の係止レバー31の下方まで後方へ向けて延設されている。この腕部41の先端部にはこれらの係止レバー31,37の下方に位置するメモリ部材28の係止ばね40に当接し得る解除押接部42が形成されている。この解除押接部42が係止ばね40に当接すると、係止ばね40がその弾性に抗して撓んで係止部材29の係止凹部39から離脱する係止解除状態Qになる。この解除押接部42が係止ばね40から離れると、係止ばね40がその弾性により復帰して係止部材29の係止凹部39に係入される係止状態Pになる。この腕部41において解除押接部42よりも前方で連動押接部43が形成されている。
【0033】
このように構成されたシートトラックスライド装置においてメモリ付きウォークインロック機構は、下記*のように作動する。
* 図3(a)及び図4,5に示す通常ロック状態
この通常ロック状態では、図2(a)に示すように、シート5のシートバック5aが起こされた状態で、アッパレール4がロアレール3に対しシート5とともに初期位置に移動調節されている。ハンドル11がロック位置11Rにあるため、ハンドルレバー12の押圧部14が上動位置にある。シートバック5aに連結された連動ロッド33によりオープン部材23が引かれていないため、オープン部材23の係止レバー31が上方へ回動し、オープン部材23の連動ピン34及び係止部31aも上動位置にある。ロックレバー16の連動部22がこの押圧部14及び連動ピン34のうちいずれかのものにより下方へ押されず上動位置にあるため、ロックレバー16がロック状態Rにある。メモリ部材28はオープン部材23の押接レバー32とキープ部材25の解除レバー36との間に位置している。キープ部材25はその係止レバー37がオープン部材23の係止レバー31に当接したところで停止している。オープン部材23における係止レバー31の係止部31aとキープ部材25における係止レバー37の係止部37aとは互いに離間している。オープン部材23における押接レバー32の下端部に形成された連動押接部32aは、メモリ部材28の後方近接位置でメモリ部材28の移動軌跡範囲内に位置する。キープ部材25における解除レバー36の下端部に形成された当接部36aは、メモリ部材28の前方でメモリ部材28の移動軌跡範囲外に位置する。押圧部材27の連動押接部43はメモリ部材28の前方近接位置でメモリ部材28の移動軌跡範囲内に位置する。押圧部材27の解除押接部42がメモリ部材28の係止ばね40を圧接しているため、係止ばね40が係止解除状態Qにある。
【0034】
* 図3(b)及び図6,7に示すオープン状態
前記通常ロック状態で、シート5のシートバック5aを図2(b)に示すように倒すと、シートバック5aに連結された連動ロッド33によりオープン部材23が引かれるため、オープン部材23の係止レバー31が下方へ回動し、オープン部材23の連動ピン34及び係止部31aが下動位置になる。ロックレバー16の連動部22がこの連動ピン34により下方ヘ押されるため、ロックレバー16がロック解除状態Sになる。オープン部材23の押接レバー32の連動押接部32aは、メモリ部材28の後方でメモリ部材28の移動軌跡範囲外に位置する。オープン部材23の係止レバー31の回動に伴い、キープ部材25の解除レバー36の当接部36aがメモリ部材28の前端部28aに当接するまで、キープ部材25の係止レバー37が回動し、オープン部材23の係止レバー31の係止部31aとキープ部材25の係止レバー37の係止部37aとが互いに面する。
【0035】
* 図8(a)及び図9に示すメモリ状態
前記オープン状態で、アッパレール4をロアレール3に対しシート5とともに図2(c)に示すように前方向きXFへ移動させると、ハンドル11とロックレバー16とオープン部材23とキープ部材25と押圧部材27もアッパレール4とともに移動する。メモリ部材28は移動せず、押圧部材27の解除押接部42がメモリ部材28の係止ばね40から前方向きXFへ離れるため、係止ばね40が復帰して係止部材29の係止凹部39に係入され、メモリ部材28が前記通常ロック状態及びオープン状態の位置で保持されてメモリ部材28の初期位置が設定される。キープ部材25の解除レバー36の当接部36aがメモリ部材28の前端部28aから前方向きXFへ離間するため、キープ部材25の係止レバー37が回動し、オープン部材23の係止レバー31の係止部31aにキープ部材25の係止レバー37の係止部37aが係入されてキープ部材25が保持状態Kになる。オープン部材23における押接レバー32の連動押接部32aはメモリ部材28の上方を前方向きXFへ通過する。押圧部材27の連動押接部43はメモリ部材28の前端部28aから前方向きXFへ離れる。なお、図示しないが、前記オープン状態で、アッパレール4をロアレール3に対しシート5とともに後方向きXBへ移動させると、メモリ部材28も押圧部材27の連動押接部43に押されて移動し、メモリ部材28の初期位置が変更される。
【0036】
* 図8(b)に示すメモリ状態
前記メモリ状態で、シート5のシートバック5aを図2(d)に示すように起こすかまたは倒したまま、アッパレール4をロアレール3に対しシート5とともに後方向きXBへ移動させると、ハンドル11とロックレバー16とオープン部材23とキープ部材25と押圧部材27もアッパレール4とともに移動する。キープ部材25の解除レバー36の当接部36aがメモリ部材28の前端部28aに当接すると、キープ部材25の係止レバー37が回動し、オープン部材23の係止レバー31の係止部31aからキープ部材25の係止レバー37の係止部37aが離脱して、図3(a)及び図4,5に示す通常ロック状態に戻る。
【0037】
* 図10に示す通常ロック解除状態
図3(a)及び図4,5に示す通常ロック状態で、ハンドル11をロック解除位置11Sにすると、ハンドルレバー12の押圧部14が下動位置になり、ロックレバー16の連動部22がこの押圧部14により下方ヘ押されるため、ロックレバー16がロック解除状態Sになる。そのロック解除状態Sでアッパレール4をロアレール3に対しシート5とともに後方向きXBへ移動させると、ハンドル11とロックレバー16とオープン部材23とキープ部材25と押圧部材27も移動すると同時に、メモリ部材28もその前端部28aで押圧部材27の連動押接部43に押されて移動する。ロック解除状態Sでアッパレール4をロアレール3に対しシート5とともに前方向きXFへ移動させると、ハンドル11とロックレバー16とオープン部材23とキープ部材25と押圧部材27も移動すると同時に、メモリ部材28もその後端部28bで押接レバー32の連動押接部32aに押されて移動する。シート5の移動調節位置で、ハンドル11をロック位置11Rにすると、図3(a)及び図4,5に示す通常ロック状態に戻る。
【0038】
なお、前記メモリ部材28を位置決めするとともにメモリ部材28の移動を許容するための係止手段としては、前記係止ばね40(板ばね)以外に、例えば、鋼球を圧縮コイルばねにより付勢してその鋼球を係止部材29の各係止凹部39に係脱させるようにしてもよい。また、この係止部材29における各係止凹部39の機能を前記ロアレール3の各ロック孔7により兼用させてもよい。
