Description

【０００１】
【発明の属する技術分野】
本発明は、高齢者や身障者が姿勢を変えるのを補助するために好適な自動車用椅子に関する。
【０００２】
【従来の技術】
筋力の衰えた高齢者や身体障害者が自力で自動車に乗り降りしたり、椅子に座った状態から立ち上がるのは困難であり、クッション性に優れた座り心地の良い椅子ほど身体が座面に沈み込むため、立ち上がったり、姿勢を変えにくかった。また、通常、自動車の扉や前座席の背板等には、移動しやすくするために手すりが取り付けられているが、このような手すりは手が届きにくく、自動車用椅子として不十分であった。
【０００３】
そこで、シートクッションの一側面近傍の車体側に配設したバー部材を部分的に上方へ傾斜させて、シートクッションに着座した乗員が把持可能なアシストグリップ部を形成した自動車のシート装置が提案されている（特許文献１参照）。
また、リヤーシートクッション側面とこれに対向するシートバックサイド或いは車体内壁面との間に手挿入用の間隙を設けると共に、該間隙内に握持部を臨ませるアシストグリップを車体パネルに取り付けた後席用アシストグリップの取付構造も知られている（特許文献２参照）。

【発明が解決しようとする課題】
しかし、先のものは、座面の上方へアシストグリップが突出しているので、このアシストグリップ側から乗降するのに邪魔になり、いずれのものも、アシストグリップがシート側に取り付けられていないため、車体側にアシストグリップを設置する作業が必要であった。
【０００６】
そこで、本発明の目的は、座面に座った状態で身体を支えるために無理なく把持体に手が届き、そのまま姿勢を変更でき、構造が簡単で、設置する場所への取り付け工事が不要な自動車用椅子を提供することにある。
【０００７】
【課題を解決するための手段】
請求項１に係る自動車用椅子は、座部の上面に配置され、前記座部と一体に設けた座面シートの前縁及び両側縁を、前記座部の外周面よりも外方へ張り出し、その先端を下方へ折り曲げて、掴んで身体を支えるための下方を開放した把持体を前記座部の外周縁の前縁及び両側縁の全長に亘って連続して設けると共に、前記座部の外周面と前記把持体との間に、親指以外の４本の指先を挿入可能な手指挿入間隙を前記座部の外周縁の前縁及び両側縁の全長に亘って連続して形成し、前記把持体は掌と前記４本の指で把持可能であることを特徴とするものである。
【０００８】
把持体を掴んで身体を支え、座部に座った状態で姿勢を変えたり、座部へ乗り降りすることができる。把持体を座部上面よりも下方に設けた構成により、把持体が上方に突出せずに乗降の邪魔にならず、座部上面に掌を当てて手先を下へ延ばすと、簡単に把持体を掴むことができる。また、直接座部に取り付けたことによって、設置場所への把持体の取付作業が不要となる。
【０００９】
【発明の実施の形態】
図１及び図２は、本発明の実施形態を示す。本発明の自動車用椅子１は、座部２の後端部から上方へ背もたれ部３が起伏可能に起立して成る。座部２の上面に座部２と一体に配置された座面シート４の前縁及び両側縁を、座部２の外周面よりも外方へ張り出し、その先端を下方へ折り曲げて、座部２の両側面から前面に亘って連続して下方を開放した把持体５を形成する。また、把持体５と座部２の外周面との間には、手指挿入間隙６が形成される。
【００１０】
この自動車用椅子１は次のように使用される。自動車用椅子１の座部２に座った状態で、座面シート４の上面外周部に掌を当て、親指以外の４本の指先を下方に延ばし、さらに４本の指先を座部２の外周面と把持体５との間に形成された手指挿入間隙６へ下から差し込んで、把持体５を掴む。すると、身体が倒れるのを防ぐことができ、この把持体５を手がかりとして座ったまま姿勢を変えることが出来る。また、自動車に乗り降りする際に、把持体５を握って身体を支えることが可能である。
【００１１】
さらに、把持体５は座部２の外周面上端部に取り付けられて、座部２の上方へ突出しないので、背もたれ部３を起伏させるリクライニング装置に影響を与えることはなく、自動車用椅子１への乗降の邪魔にならない。また、座面シート４と一体に形成した把持体５は、上記したように背もたれ部３が配置されていない前縁及び両側縁の全長に亘って、座部２と一体に把持体５を設けてあるので、把持体５を把持した指を座部２の側面から前面に、あるいは前面から側面に滑らせることができる。
自動車の後部座席に把持体５を設ける場合は、背もたれが装着されていない縁部全長に亘って把持体５を配設すると、この把持体５に沿って片手ずつ手を滑らせながら、身体をずらして移動することもできる。
【００１２】
【発明の効果】
請求項１に係る発明によれば、座部に掌を付いて手指を下方へ延ばすと、簡単に把持体へ手先が届き、この把持体を掴んで身体を支えることにより、筋力の弱った高齢者や身体障害者が、座った状態で姿勢を変えたり、座部へ座ったり起立する動作の手がかりとすることができる。
また、構造が簡単でコストが低廉で済み、把持体が座部へ一体に設けられているので、設置場所に把持体を取り付ける工事が不要であり、把持体が座部よりも上方へ突出しないため、立ったり座ったりする際に邪魔にならない。
【００１３】
さらに、座部前面及び両側面のどの部分に手を延ばしても把持体を掴むことが可能であり、把持体を把持した指を座部の側面から前面に、あるいは前面から側面に滑らせることができ、移動する度に指を離して持ちかえる必要がない。
把持体を掴んで身体を支え、転倒するのを防止でき、自動車のシートベルトと併用することによっていっそう安全性が高まり、また、自動車への乗り降りが容易となり、車体側へアシストグリップ等の把持体を取り付ける作業が不要となるばかりか、自動車ドアに装着されている手すり等の身体安定装置を簡略化して、製造コストを削減できる。さらに、把持体が座部の外周面外方へ設けられるので、リクライニング機能に悪影響を与えることもない。
