これによれば、取り付け部は、直線部を有さないので、応力の分散均一化を好適に実現することができる。
これによれば、取り付け部は、直線部を有さないので、応力の分散均一化を好適に実現することができる。
これによれば、第1の付勢部及び第2の付勢部で付勢する向きが逆となる、所謂、ねじりばねとして作用するスプリングであっても、応力の分散均一化を好適に実現することができる。
以下、図1~図6を参照して車両用シートスライド装置の第1の実施形態を説明する。
図1及び図2に示すように、車両フロア11には、車両の前後方向Lに延びる左右一対のロアレール30が固定されている。これらロアレール30には、対応するロアレール30上を該ロアレール30の長手方向に沿って相対移動する左右一対のアッパレール40が装着されている。そして、車両用のシート12は、アッパレール40の上方に支持されている。本実施形態では、これらロアレール30及びアッパレール40によって、車両用シートスライド装置10が形成されている。
図1及び図3に示すように、ロアレール30は、車両フロア11に固定される板状の底壁部32を備えている。底壁部32の幅方向Wの両端には、それぞれ外壁部31が立設されている。これら外壁部31の上端には、それぞれ幅方向Wの内側に折り返された折り返し部33が延設されている。
図5(a)に示すように、スプリング50は、線材を2つ折りにして上面視略U字状のスプリング本体51を備えている。このスプリング本体51の線材を2つ折りにして得られる2本の足部52には、取り付け部としての係止部53がそれぞれ形成されている。各係止部53は、連続した曲げ形状をなす上面視略U字状に折り曲げられている。この連続した曲げ形状は、各係止部53の外周に沿って接線の傾きが連続的に変化する弧状を示し、その途中で曲率の正負が変わらないことを示す。
図1に示すように、ロックレバー20は、係止爪23a~23cと反対側の端部に前端部24を有する。ロックレバー20の前端部24には、パイプ材を折り曲げ加工して形成された操作ハンドル60が接続されている。この操作ハンドル60は、シート12の幅方向Wに沿うように当該シート12の前方に配置される操作部61と、左右のアッパレール40に沿って延びる一対の挿入部62とを備えた周知の構成を有している。そして、操作ハンドル60は、その挿入部62の先端62aがアッパレール本体内に挿入された状態で、アッパレール40の前方開口部40aから延出している。
図6に示すように、スプリング50をアッパレール40の下方から上方に挿入するようにして、各係止部53が対応する係止孔48に挿入される。この挿入の際、まず足部52の当接部55a及び当接部55bが上記幅W1a及び上記幅W1b(図6中、一点鎖線に示された足部52)に開いたスプリング本体51は、足部52が互いに近接する方向に弾性変形される。また、スプリング本体51は、各係止部53の先端がアッパレール本体内に挿入可能になるまで弾性変形させる。これにともない、スプリング本体51は、足部52が互いに交差するように(図6中、二点鎖線に示された足部52)、弾性変形する。
スプリング50のアッパレール40への取り付けは、スプリング50、すなわち各係止部53をアッパレール40の対応する上縁45aめがけて当て込んで対応する係止孔48に挿入することによりなされる。また、スプリング50のアッパレール40への取り付けは、スプリング本体51を弾性変形させて各係止部53を対応する係止孔48に挿入すれば、該各係止部53を対応する係止孔48の周縁に係止させることができる。このような係止を通じては、スプリング50をアッパレール40に取り付ける際、各係止孔48に対する対応する係止部53の位置決めが容易となるとともに、スプリング50のアッパレール40に対する位置決めと、アッパレール40に対する締結とを併せてなすことができる。
(1)スプリング50、すなわち各係止部53をアッパレール40の対応する上縁45aめがけて当て込むとともに、スプリング本体51を弾性変形させて各係止部53を対応する係止孔48に挿入することにより、スプリング50をアッパレール40に取り付ける際、各係止孔48に対する係止部53の位置決めを容易にすることができる。さらには、スプリング50のアッパレール40に対する位置決めと、アッパレール40に対する締結とを併せて行うことができる。これにより、スプリング50をアッパレール40に取り付けるための工程及び構成を簡素化することができる。即ち、スプリング50をアッパレール40に取り付ける際、スプリング50組付性を向上することができる。
(4)また、本実施形態のスプリング50のように、所謂、ねじりばねとして作用するスプリングであっても、応力の分散均一化を好適に実現することができる。
図7~図9(b)を参照して第2の実施形態について説明する。本実施形態の車両用シートスライド装置1は、図7に示すように、第1の実施形態と同一の構成要素を備える。そのため、第1の実施形態と同様の部材についてはその説明を省略する。第2の実施形態では、第1の実施形態と比較して、特にスプリングの形状が異なる。
(9)スプリング50の一対の開放端57は、幅方向Wの内側に向かって延出する。この構成では、両開放端57は、係止部材20に線接触可能である。よって、スプリング50が係止部材20に接触する面積が大きくなる。従って、スプリング50によって係止部材20を安定して保持することができる。
・折り曲げ部54は、特に形成されていなくてもよい。ただし、この場合にも線材を折り曲げることによっては、幾らかのR(曲率)、所謂、最小Rを有する部位が形成されるので、この部位を折り曲げ部として作用させることもできる。
・ロックレバー20の後端部23を下方に付勢する機能と、操作ハンドル60を上方に付勢する機能とを別々のスプリングに持たせる仕様の車両用シートスライドに適用することもできる。その際には、少なくとも何れかのスプリングが本実施形態に示した方法でアッパレール40に取り付けられていればよい。
・アッパレール40の二つの側壁部44の少なくとも何れかに係止孔48が形成されていればよい。
・後方本体部51a及び前方本体部51bで同じ方向へ付勢する力を発揮するスプリングを用いた仕様の車両用シートスライドに適用することもできる。
