Description
前記回動機構は、一端を前記受台に回動可能に軸支し、他端を前記背もたれに固定し、背もたれを傾動させる回動アームと、前記受台内部に設けられ、前記回動アームの軸を巻回部に遊嵌し、一端を回動アームに係止し、他端を背もたれを後傾動させる回動アームの動きに対して戻し方向に付勢力が生じるように固定したねじりコイルばねからなる第1弾性手段と、背もたれを後傾動させる回動アームの動きに対して前記座部の前方向と水平な引張り方向の付勢力を有する第2弾性手段とを有し、
前記第1弾性手段及び第2弾性手段は、前記背もたれが後傾動するに従い、前記戻し方向の付勢力と前記引張り方向の付勢力との合成された付勢力により、後傾動の傾斜角度が大きくなるにつれて、背反力が増大し、次第に後傾速度を抑え、戻り傾動と後傾動との背反力の差が小さくなるように弾性特性を調整させたものであることを特徴とする。
引張りばね58についても、図1で説明したとおり、ベース部51前方に、掛止ピン51aを、内部ベース部57に掛止ピン57aを各々設けている。

Claims (3)
- 脚支柱の上部に固定された受台と、この受台の上部に設けられた座部と、この座部の後方に立設された背もたれとを有し、この背もたれを傾動させるために、回動機構を備えた椅子であって、
前記回動機構は、一端を前記受台に回動可能に軸支し、他端を前記背もたれに固定し、背もたれを傾動させる回動アームと、前記受台内部に設けられ、前記回動アームの軸を巻回部に遊嵌し、一端を回動アームに係止し、他端を背もたれを後傾動させる回動アームの動きに対して戻し方向に付勢力が生じるように固定したねじりコイルばねからなる第1弾性手段と、背もたれを後傾動させる回動アームの動きに対して前記座部の前方向と水平な引張り方向の付勢力を有する第2弾性手段とを有し、
前記第1弾性手段及び第2弾性手段は、前記背もたれが後傾動するに従い、前記戻し方向の付勢力と前記引張り方向の付勢力との合成された付勢力により、後傾動の傾斜角度が大きくなるにつれて、背反力が増大し、次第に後傾速度を抑え、戻り傾動と後傾動との背反力の差が小さくなるように弾性特性を調整させたものであることを特徴とする椅子。
- 前記第2弾性手段は、前記受台内部に設けられ、一端のフックを前記受台の前記座部前方側に設けられた固定掛止部に掛止し、他端のフックを回動アームの動きに連動するように、前記軸に取り付けられた連動部に前記引張り方向の付勢力が生じるように掛止された引張りばねであることを特徴とする請求項1記載の椅子。
- 前記座部の着座面は、前記傾動時に、着座面上で骨盤の圧力中心の移動を前後の広い範囲で生じさせ、坐骨結節前方部を支えるように、坐骨結節部を深く沈みこませる構造であることを特徴とする請求項1または請求項2に記載の椅子。
