Claims (7)
- 脚に支持されたベース部材と、該ベース部材に回転軸を介して後傾可能に連結されて背もたれを支える背支持部材と、座が取り付けられた座支持部材と、前記背支持部材を後傾させる際に前記座支持部材を持ち上げる方向に連係動作させる体重対応式反力機構と前記背支持部材を原位置に復帰させるばね力を負荷する反力ばねとを有する椅子の背凭れ用反力機構において、前記反力ばねを前記背支持部材と前記ベース部材との間に横向きに配置したことを特徴とする椅子の背凭れ用反力機構。
- 前記反力ばねは前記背支持部材の回転軸よりも前方に配置されているものである請求項1記載の椅子の背凭れ用反力機構。
- 前記反力ばねは前記背支持部材の回転軸よりも後ろに配置され、一端が前記背支持部材に他端が前記ベース部材にそれぞれ回転自在に取り付けられ、前記背支持部材の動きとともにその傾きを変化させるものである請求項1記載の椅子の背凭れ用反力機構。
- 前記反力ばねとして圧縮コイルばねを用い、該圧縮コイルばねを前記背支持部材または前記ベース部材のいずれか一方に取り付ける端部に前記反力ばねを回転自在に軸受けすると共に前記反力ばねの長さ方向成分の変位を与えて前記反力ばねの初期圧縮量を調整する反力ばね位置調整装置を備えるものである請求項1記載の椅子の背凭れ用反力機構。
- 前記ベース部材と前記背支持部材との間に互いに係合するロック機構を備え、該ロック機構は前記ベース部材側に取り付けられる固定部材と前記背支持部材側に取り付けられる可動部材とで構成され、前記可動部材側には回転軸を中心に旋回動作して両端が前記固定部材と交差するストッパ部材と該ストッパ部材を旋回動作させる駆動部とを備え、前記固定部材側には前記ストッパ部材の両端部が嵌まり込む孔または凹部を前記背支持部材の回転方向に複数段備えているものである請求項1に記載の椅子の背凭れ用反力機構。
- 前記ロック機構には、前記ストッパ部材を前記固定部材側の孔または凹部に向けて付勢する第1のばねと、前記ストッパ部材と前記駆動部材との間に介在され前記駆動部材の動きを前記ストッパ部材に伝達する第2のばねとを備え、前記駆動部のロック動作あるいはロック解除動作に対して前記ストッパ部材が追従できないときには前記第2のばねの伸縮により前記駆動部と前記ストッパ部材との連係動作を切り離すと共に前記駆動部材の変位を吸収してばね力として蓄え、前記ストッパ部材にかかる前記固定部材との間の摩擦力が軽減されたときに前記第2のばねに蓄えられたばね力で前記ストッパ部材を旋回させるものである請求項5記載の椅子の背凭れ用反力機構。
- 請求項1に記載の背凭れ用反力機構を組み込んだ椅子。
