(102b), so it plays a role in keeping the line of the buttocks from being damaged even in a long sitting position.

The upper footrest 200 is attached to both sides of the user's legs under the buttock cushion 102 of the chair 100, has a 'L' shape from the front, and has a center of rotation 201a inside a rectangle from the side. One hole and a bracket 201 in which a groove of a sectoral arc 201b is formed over a certain angle around the hole; and the bracket 201 in a flat boomerang shape attached to both outer surfaces of the bracket 201 ) has two holes for angle adjustment in the direction, and the bracket 201 has one hole in the opposite direction to the fixing plate 202; and the fixing plate 202 passes through the holes located in the opposite direction to the bracket, and has a circular shape. A roller shaft 203 having a screw hole in the center of both ends of the shaft; and the roller shaft 203, located on the outer circumferential surface, around the rim of the round surface of the cylinder, semi-circular projections surround all directions, and at the center of the side A foot pressure roller 204 having a hole for inserting the roller shaft 203; is fastened to both end surfaces of the roller shaft 203 to fix the fixing plate 202 and the roller shaft, and bolts to the center of the disc A cap 205 having a hole and a groove to be fitted with the roller shaft; and a handle attached to the side of the fixing plate 202 to adjust the fixing position of the fixing plate, and a handle for turning by hand. Small semicircles around the disk are sunflower-shaped and a knob bolt a (206) with one round end serving as a flat washer, followed by a screw bolt portion.

In particular, in the foot pressure roller 204, the fixed plate 202 moves in an arc along a sectoral arc 201b based on the rotation center 201a of the bracket 201. By fastening the bracket 201 and the fixing plate 202 with the handle bolt a (206), the position is adjusted to adjust the height according to the user's convenience.

In the same configuration as the upper footrest 200, the height of the foot acupressure roller 204 is raised to the hip position so that the user can squat by pulling the knee from the chair toward the chest, thereby relieving the pressure of the part where the thigh and the chair abut. As the position of the legs becomes closer to the heart, the blood concentrated on the legs circulates throughout the body, thereby relieving fatigue caused by long sitting postures.

In addition, when not using the foot acupressure roller 204 with reference to Fig. 1d, the position of the fixing plate 202 attached to the bracket 201 is adjusted with the handle bolt a (206) to prevent the foot acupressure roller from interfering with the user's leg. You can move to a location that doesn't work.

The foldable double seat 300 is fastened to both sides of the back of the buttock cushion 102 of the chair 100 and protrudes upwards, and a fixture 301 having a hole in the upper part of the rectangular plate; and the fixture ( 301), there is a hexagon wrench groove in the mushroom head, and a circular end with a bolt screw opposite the groove and a pin bolt 302 with a circular pin at the end; and the pin bolt 302 is inserted into the circular pin , a bush 303 having a hole penetrating through the center in a two-stage cylindrical structure; and assembled in close contact with the circular ends of the bushes on both sides of the chair, having a rectangular shape in plan and an oval shape along the shape of the buttocks (304a) ) is dug symmetrically, and the center protrudes in a 'S' shape (304b) along the shape of the hip bone, and a two-stage cushion 304 with a hole in the seat toward the back of the side chair; includes.

In particular, the two-stage cushion 304 has a function of adjusting the use or absence of the two-stage cushion in a manner that is bent 90 degrees based on the central axis of the pin bolt 302 fastened to the fixing base 301, Accordingly, it is possible to adjust the height of the buttock seat cushion with the foldable double seat 300 proposed by the present invention without a separate cushion.

In addition, referring to FIG. 1A , the two-stage cushion 304 is ergonomically designed according to the shape of the buttocks, and is symmetrically dug in the form of an oval (304a), and the center is a 'S' shape along the shape of the hip bone. It protrudes in the shape 304b, and serves to prevent the hip line from being damaged even in a long sitting posture.

The arm seating part 400 has the shape of two square plates positioned in close contact with both sides of the side holder 104, and a plurality of position adjustment holes 401a1 in the side outward direction and the position adjustment in the side inward direction plate. A square plate 401a in which a screw hole 401a2 is formed at a position corresponding to the hole 401a1, and a V-groove 401b1 in the shape of a disk attached to the upper portion of the square plate 401a are formed at the same radius from the center An adjustment table 401 including a disk 401b formed at regular intervals; and the position adjustment hole 401a of the side of the adjustment table 401 and the straight groove 104a and the screw hole 401b of the side holder 104 Inserted A sunflower-shaped handle for turning by hand, a circular end protruding from the side of the handle, and a circular pin matching the size of the positioning hole 401a1 protruding from the end of the circular end, and at the end of the circular pin A handle bolt b (402) having an extended and protruding screw bolt; and a steel ball (403) seated in the V groove (401b1) of the disk (401b); and the steel ball (403) in the form of a disk covered over the disk There is an end dug under the arm seat plate 404 having a cylindrical shaft extending downward from the center and a screw hole on the bottom surface; and the arm seat plate 404 is fastened under the arm seat plate to prevent separation of the arm seat plate and a cover 405 with a countersunk head bolt fastening seat in the center in the form of a disk.

In particular, the arm seating part 400 is a coupling position between the straight grooves 104a of the side mounts formed in the front-rear direction and the position adjustment holes 401a of the plurality of adjustment bars 401 configured in the up and down directions, and the front and rear, up and down positions are adjusted. This is possible, and the function is to assist the movement of the arm by rotating the arm seating plate by point contact between the steel ball 403 seated in the V groove 401c and the arm seating plate 404 covered over the steel ball, It supports the load applied to the arm through the arm resting part and serves to assist the movement.

As a feature of the chair equipped with the upper footrest and foldable double seat of the present invention having the configuration as described above, it helps to recover from fatigue by raising the feet up to the hip level and squatting to help the circulation of blood rushed to the legs. Through the hip cushion 102 designed according to the shape, the hip line is corrected and the hip seat height is adjusted without a separate cushion through the self-constructed hip foldable double seat 300, and through the arm seat 400 By supporting the load on the arm and helping the movement, it can be expected to reduce the fatigue of the arm and shoulder.
