【0010】
【発明の実施の形態】
次に、本発明にかかる椅子等の座部装置について、車椅子に用いた一つの実施の形態を示すと共に、添付の図面に基づいて、以下説明する。
図1に車椅子1を示し、この車椅子1では、前輪2と、前輪2に比較して大径な後輪3を装着したベースフレーム4と、ベースフレーム4に前記前輪2前方に突出するフットレスト5を保持してなるフットフレーム6と、ベースフレーム4から後輪3上方に延在する背フレーム(図示省略)と背フレームに連なるハンドル部7と、ベースフレーム4における背フレーム取付箇所近傍から、前記フットフレーム6取付箇所にかけて配置してなる座部8と背フレームに沿って配置した背部9とを備え、前記座部8両側面に跳ね上げ、着脱可能なアームレスト装置10を配置するようにしている。
【0011】
前記アームレスト装置10は、前記ベースフレーム4上の、背フレーム取付箇所近傍から、前記フットフレーム6取付箇所にかけて配置してなる支持部材11と、支持部材11に装着した肘当部材12とガードパネル13とを備え、前記支持部材11は、前記ベースフレーム4に、背フレーム側の端部を回動着脱支持機構14を介して取り付ける一方、フットフレーム6取付箇所側の端部をロック機構15を介して着脱可能に装着する構成としている。
【0012】
かかるアームレスト装置10間にある前記座部8は、前記ベースフレーム4上に、例えばボルトなどの固定手段により、着脱可能に装着した座板16とこの座板16上に載置したクッション部17とによって構成してもよい(図2参照)。
前記座板16は、例えば鋼板をプレス加工、溶接して形成したもので、双方のベースフレーム4上に載置して、ボルト止めする側縁部16sと、フットフレーム6取付箇所寄りに位置させて、膝裏から大腿部にかけて支える前座部16fと、この前座部16fに比較して低位置に段差形成し、腰部を支える後座部16bとを有している(図3参照)。
これら前座部16fおよび後座部16bには、複数の通気用穴hを形成している。また、前座部16fおよび側縁部16s、後座部16bには、それぞれクッション部17のずれ止め用リブRを形成している。
さらに、前座部16fの後座部16b寄り中央と、側縁部16sの背フレーム寄り、そして後座部16bの後縁部に、クッション部17を滑られないように保持するラバーRuを付設している。
【0013】
そして前記クッション部17は、周知の適度な反発性を有する詰物(後述)をビニールレザーなどの表地で覆ったもので、底面に、座板16に隙間なく係合するように、後座部16bに対応する突出部17aを設けている。一方、上面は、前座部16fに対応する箇所から後座部16bに対応する箇所にかけて、若干の俯角をなすように傾斜している(図4参照)。
前記クッション部17の前座部16fに対応する箇所の底面には、所定長さの開口部Oを構成し、この開口部OにファスナF1を付設して開閉可能に構成している(図5参照)。
さらに、前記突出部17aの、背部9側に向く端面に沿って開口部Oを構成して、この開口部OにファスナF2を付設して開閉可能に構成している(図6参照)。
【0014】
ここで、前述のクッション部17の詰物を具体的に例示する。すなわち、詰物としては、例えばウレタンフォーム、チップウレタン、低反発フォームウレタン、さらには圧力分散ゲル等を挙げることができる。
【0015】
以上のような座部8を有する車椅子1によれば、車椅子1を使用するに当たり、座板16は、側縁部16sを、双方のベースフレーム4上に載置して、ボルト止めすることで固定することができる。次いで、クッション部17を後座部16bに突出部17aを満たすように合わせて座板16に載置する。この時、前座部16fの後座部16b寄り中央と、側縁部16sの背フレーム寄り、後座部16bの後縁部に付設したラバーRuによってクッション部17を滑らないように保持することができる。
【0016】
以上のようにして装着した座部8に座ると、適度な反発性を有するクッション部17を介し、座板16によって沈み込むことなく安定姿勢を保つことができる。しかもこの時、前記座部8のクッション部17は、上面が、前座部16fに対応する箇所から後座部16bに対応する箇所にかけて、若干の俯角をなすように傾斜しているので、背部9側と後座部16b側に体圧がかかり、安定性が増す
【0017】
また前記座部8に座ることで、臀部における座骨の箇所は後座部16bにもたらされるが、前座部16fに比較して低位置に段差形成した後座部16bには、クッション部17 のうち、肉厚の突出部17aが満たされ、この突出部17aにおけるクッション性によって、座骨にかかる体圧を効果的に分散させることができ、長時間座っていても疲れを少なくすることができる
【0018】
ところで、クッション部17のクッション度合が柔らかすぎたり、堅すぎたりして、適切なクッション性が得られないときは、クッション部17の前座部16fに対応する箇所の底面の開口部OをファスナF 1 によって開口し、中の詰物の素材を変える。
また、座板16の後座部16bに満たされるクッション部17の突出部17aのクッション性も、突出部17aの、背部9側に向く端面の開口部OにおけるファスナF 2 を開き操作し、詰物を詰め替えことで所望のクッション性を得ることができる。
【0019】
なお、前述のように座部8の座板16は取り外しが容易なので、非使用時には、これまでの車椅子のように双方のベースフレーム4を合わせるように折畳んで保管しておくことができる。
【0020】
以上、本発明にかかる椅子等の座部装置8について、車椅子1に用いた例を挙げ、説明したが、かかる座部8は、勿論、通常の椅子18に用いることも可能である(図7参照)。
【0021】
