- 基体と、この基体の後側に第1の支軸により上下揺動自在に支持された背支持体と、前記基体の上側に上下揺動自在に支持されるとともに前記第1の支軸よりも後方に位置する第2の支軸により後部が前記背支持体に回動自在に連結された座支持体と、前記基体に対して前記背支持体および前記座支持体を付勢する反力機構と、この反力機構が前記座支持体に付与する力を変更する反力調整機構とを備え、前記反力機構は、前記座支持体内に常時位置するように前記基体に揺動自在に支持されるとともに前記座支持体に対しては摺動自在に支持されたばね支持体と、このばね支持体と前記座支持体との間に設けられた反力ばねとを有し、前記反力調整機構は、上下方向の軸の回りで前記反力ばねの角度を変更することにより、前記座支持体に付与する力を変更することを特徴とする椅子の反力調整装置。
- 前記反力ばねは、左右一対あり、前記反力調整機構は、前記一対の反力ばねの角度を左右対称に変更することを特徴とする請求項1記載の椅子の反力調整装置。
- 前記反力調整機構は、前記座支持体に回動自在に支持され左右両側でねじの向きを逆にした一本のねじ軸を有し、このねじ軸の左右両側にばね取り付け駒をそれぞれ螺合し、これらばね取り付け駒と前記ばね支持体との間に反力ばねを設けたことを特徴とする請求項2記載の椅子の反力調整装置。
- 基体と、この基体の後側に第1の支軸により上下揺動自在に支持された背支持体と、前記基体の上側に上下揺動自在に支持されるとともに前記第1の支軸よりも後方に位置する第2の支軸により後部が前記背支持体に回動自在に連結された座支持体と、前記基体に対して前記背支持体および前記座支持体を付勢する反力機構と、この反力機構が前記座支持体に付与する力を変更する反力調整機構とを備え、前記反力機構は、前記座支持体内に常時位置するように前記基体に揺動自在に支持されるとともに前記座支持体に対しては摺動自在に支持されたばね支持体と、このばね支持体と前記座支持体との間に設けられた1本の反力ばねとを有し、前記反力ばねの長さを変更することにより、前記座支持体に付与する力を変更することを特徴とする椅子の反力調整装置。
- 前記反力調整機構は、椅子の幅方向に配置され且つ前記座支持体に回動自在に支持された一本のねじ軸と、前記ねじ軸に螺合されたカム体と、前記カム体によって椅子の前後方向に移動される従動体を有し、前記従動体と前記ばね支持体との間に前記反力ばねを設け、前記ねじ軸の回転操作により前記カム体が椅子の幅方向に移動すると、前記従動体が椅子の前後方向に移動して前記反力ばねの長さを変更することにより、前記座支持体に付与する力を変更することを特徴とする請求項4記載の椅子の反力調整装置。
- 前記ばね支持体は、前部が前記基体に揺動自在に支持されると共に、後部が前記座支持体に対して摺動自在に支持されていることを特徴とする請求項1、4、5のいずれか一つに記載の椅子の反力調整装置。
