のである。2. Description of the Related Art Generally, when an operator handles a lot of office work, the working time in a sitting state becomes long, and fatigue is induced in the body based on maintaining a sitting posture for a long time. There are many. Therefore, to alleviate the fatigue of the seated person for such long working hours,
A chair has been proposed in which the seat is slowly tilted at a constant cycle. Such a chair is provided with a backrest part and a seat part separately, and slowly tilts the seat part around the tilt fulcrum position to reduce fatigue of the seated person's buttocks and thighs,
It is designed to reduce swelling of the lower limbs and fatigue of the lower back.

んでしまう可能性がある。However, when the backrest portion and the seat portion are separately configured as described above, the seat portion is tilted at a constant cycle, and depending on the tilt fulcrum position, the seat portion may be rearward. The clearance gap with the lower end of the backrest changes periodically. Particularly, when the seat is tilted downward and forward, the rear end of the seat lifts up and the clearance with the lower end of the backrest narrows. Therefore, there is a possibility that clothes or the like of the seated person may be caught in that portion.

Is moved up and down, and more specifically, A-A
As shown in FIG. 3, which is a cross-sectional view, an eccentric portion 74 having a circular rotating member is fixedly attached to a shaft extending from the joint 73, and a holding member 76 that rotatably holds the eccentric portion 74. The circular opening 7 having the same shape as the outer shape of the eccentric portion 74
7 is provided to allow the eccentric portion 74 to rotate therein, whereby the holding member 76 and the lifting arm 75 are provided.
Is moved up and down at regular intervals. A guide portion 75a for guiding the vertical movement of the elevating arm 75 and a front bearing 79 for rotatably holding the pin 78 are provided above the elevating arm 75.
By making 8 penetrate, the front of the seat part 3 is regularly raised and lowered at a constant cycle.

せる。First, while the seated person is seated, the power switch SW provided on the side surface of the casing 5 is turned on to supply electric power to the motor 70. Then, the motor 70 is driven to rotate a motor rotating shaft (not shown), and the rotation is reduced by the speed reducer 71 to transmit the rotational force to the eccentric portion 74 via the joint 73.
Then, the eccentric portion 74 is rotated about the rotation shaft 72,
The holding member 76 that holds the eccentric portion 74 and the elevating arm 75 attached to the holding member 76 are moved up and down along the guide portion 75a at regular intervals. Then, based on the raising and lowering of the raising and lowering arm 75, the front of the seat portion 3 is raised and lowered by the pin 78 and the front bearing 79, and based on this raising and lowering operation, it is provided at the boundary between the waist support portion 6 and the backrest portion 21. The seat 3 is slowly tilted at a cycle of about 15 to 20 seconds with the shaft 22u of the link member 22 as a fulcrum.

るようにしている。When the front bearing 79 is moved vertically upward, the linear distance between the front end portion of the seat portion 3 and the shaft 22u above the link member 22 becomes short as shown in FIG. When the bearing 79 is moved vertically downward, the seat portion 3
Although the linear distance between the front end of the link member 22 and the shaft 22u above the link member 22 becomes long, the connecting angle between the link member 22 and the seat portion 3 is changed so that the lower end portion of the link member 22 and the upper end portion of the waist support portion 6 are The amount of change in the distance is absorbed by projecting it forward, and the amount of change in the distance can be absorbed by elastically deforming the synthetic resin seat 3.

2d moves forward, and similarly, the upper end portion of the waist support 6 also moves forward. As the seat portion 3 is inclined forward and downward in this manner, the blood circulation in the buttocks and thighs is improved and the vicinity of the lumbar region of the seated person is pressed to push the muscles to move the lumbar spine. Then, by repeating this tilting motion in a constant cycle, fatigue of the buttocks and thighs, swelling of the lower limbs, and fatigue of the lower back are alleviated.
