Claims (5)
- 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、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を有する第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、背もたれの後傾動で線形的に背反力が大きくなるとともに、戻り傾動における背反力の変化が前記後傾動と同相と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1弾性手段は、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、他端を背もたれの後傾動に抗する付勢力が生じるように固定したねじりコイルばねであることを特徴とする請求項1記載の椅子。
- 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または請求項2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から請求項3までのいずれかに記載の椅子。
- 前記背もたれのシートは、前記後傾動時に、徐々に胸郭を後方に解放し、骨盤を後方から支えるものであることを特徴とする請求項1から請求項4までのいずれかに記載の椅子。
