摘要： The chair has a simple structure in which a seat can follow a free movement of a seated person in front-rear, left-right, and diagonal directions, a burden from an operation by which the seated person balances his or her load can also be reduced, and a movement by which the seated person changes his or her posture stably and continuously can be suitably supported. The chair includes a movement mechanism 3 that causes an upper base unit (31) to swing in a direction of 360 degrees with respect to a lower base unit (32), and a seat 1 attached to the upper base unit (31). The chair further includes a damper mechanism (DM) that may operate by following a movement in a direction of 360 degrees, as a mechanism separate from the movement mechanism (3), at a position connecting the upper base unit (31) and the lower base unit (32).

摘要： [Problem] Provided is a chair capable of changing an operation of a movable part between allowed and suppressed states, without causing an up-down movement of a seat or without requiring a complicated structure relying on a back.
[Solution] For that purpose, a weight-receiving part 50, the height position of which changes due to a person sitting on a seat surface, is provided on a seat 5, the change of the height position is mechanically transmitted to a control mechanism 8X configured to control an operation of a front-rear swing part 3 being the movable part, and the control mechanism 8X changes an operation of the front-rear swing part-3 being the movable part between allowed and suppressed states.

摘要： In case the seat portion of the inclining chair is inclined periodically, if a supporting shaft to incline the seat portion is arranged away from a position supporting an ischial tuberosity portion of a seated person in an ordinary posture of sitting, an upper body of the seated person makes an up and down movement widely in compliance with a periodical inclining movement of the seat portion, which might cause dizziness due to a vertical shock to the upper body of the seated person. The supporting shaft 61d to incline the seat portion 3 periodically is arranged near an ischial tuberosity portion HB of a seated person in an ordinary sitting posture, namely, at the rear of a center CL1 along a back and forth direction of the seat portion 3. More specifically, the supporting shaft 61d is arranged within a range of 50 mm to 180 mm in front of a front face of a backrest so that fatigue of a hip, a femur, a lumber and a back and tumefaction of a lower limb of a seated person are mitigated and occurrence of dizziness is reduced as well.
