Title: Chair
Inventor: MIYASHITA MASAMITSU
IPC: A47C1/024
Filed: 1987-07-31
Abstract: PURPOSE: To easily move a backrest and a seat part in working and when a resting posture is taken by providing a mechanical elastic body acting as a balancer for balancing the moment around the fulcrum point of a balance member, and a regulating means for regulating the elastic force of the mechanical elastic body. CONSTITUTION: When a person sits on a seat part 23, the load is divided to working point parts in the front and rear of the turning shaft 24 of a balance member 22, one force imparts a clockwise moment around the turning shaft 24 to the balance member 22 through a link plate 32, and the other imparts a counterclockwise moment through a link 27. Since the load is divided around the fulcrum point of the balance member 22 when a resting posture is taken, and the balance portion is offset by the balancing action, the clockwise moment is relatively small. When the person leans against a backrest 25 in working, the backrest 25 can be tilted slightly backward to take an easy posture since the strength of a tensile spring 35 is not so much large. Namely, both a heavy person and a light person can easily tilt the backrest 25 against the tensile force of the tensile spring 35.
