The present ergonomic computer chair relates to chairs for special purposes, and more particularly, to computer operator's chair which is ergonomically designed to prevention of orthopedic and cardiovascular diseases and creation of psychophysical comfort, especially as regards reduction of fatigability during long-lasting work with computer. The ergonomic computer chair includes a seat with a backrest and a pedestal with a support frame made in the circular arc form, a support ring installed on the support frame wherein said support ring can rotate around its axis. The backrest is made of a rigid part and an elastic part separated from one other by at least three elastic bladders connected to a compressor by air tubes having electric valves. The rigid part of the backrest is hinged to the seat, and the seat is hinged to a seat inclination drive and to a footrest. A mounting of the computer monitor and keyboard is made by means of a movable sector which is made as a arched pipe with centering bearings. The chair has electric drives to move the support ring along the support frame of the pedestal, to move the movable sector along the support ring, to move the monitor longitudinally and to control monitor's inclination. This makes it possible to change the user's body position within the space against the Earth's gravitational field vector during the entire time of the work with computer. The use of the proposed device reduces the probability of orthopedic diseases occurrence, creates comfort and increases efficiency of the computer user.

1. An ergonomic computer chair comprising: a pedestal with an arched support frame;a support ring installed on the support frame, wherein the support ring can rotate around its axis;a seat with a backrest;a monitor; anda computer keyboard which are all coupled to the support ring,wherein the support frame is made of an arched pipe with two centering bearings fastened therein at two opposite ends for movably mounting said ring into said frame;wherein the backrest of the seat is made of a rigid part and an elastic part separated from one another by at least three elastic bladders connected by means of air tubes equipped with electrical valves to a compressor placed between said rigid and elastic parts;wherein the coupling of said monitor and keyboard to said ring is realized by means of a movable sector which is made of the arched pipe with two centering bearings fastened therein at two opposite ends for movably mounting said sector around said ring; andwherein said ring is hollow, and electrical conductors are passed through said hollow ring in the direction from a power supply unit, said computer system unit and an audio amplifier to said compressor, monitor, electric drives, electric valves, illuminating lamps and loud speakers. 2. The chair according to claim 1, wherein a mean arc radius of said arched pipes is substantially equal to a mean radius of said ring. 3. The chair according to claim 2, which is provided by an electric drive to move said movable sector along said ring, an electric drive for longitudinal monitor movements and an electric drive controlling monitor inclination. 4. The chair according to claim 3, wherein said pedestal comprises a niche to accommodate a computer system unit. 5. An ergonomic computer chair comprising: a pedestal with an arched support frame;a support ring installed on the support frame, wherein the support ring rotates around an axis;a seat with a backrest connected to the support ring;a monitor connected to the support ring; anda computer keyboard connected to the support ring;wherein the support frame is made of an arched pipe having two bearings fastened therein at two opposite ends for movably mounting the support ring into the frame;wherein the backrest of the seat is made of a rigid part and an elastic part separated from one another by at least three elastic bladders, wherein the elastic bladders are connected by air tubes equipped with electrical valves to a compressor placed between the rigid and elastic parts;wherein when fatigue signs due to immovable position of spinal articulations are starting to show, expanding the bladders causes the elastic part of the backrest to change its form, at the same time the pressing force of the gravitational field changes the form of the spine of a user of the seat. 6. The chair according to claim 5, wherein the connection of the monitor and the computer keyboard to the support ring is realized by a movable sector made of an arched pipe, the movable sector having opposite ends fastened to the bearings for movably mounting the movable sector around the support ring. 7. The chair according to claim 6, wherein a mean arc radius of the arched pipe is substantially equal to a mean radius of the support ring. 8. The chair according to claim 6, further comprising an electric drive to move the movable sector along the support ring, an electric drive for longitudinal monitor movements and an electric drive controlling monitor inclination. 9. The chair according to claim 5, wherein the pedestal comprises a niche to accommodate a computer system unit. 10. The chair according to claim 5, wherein the support ring is hollow, and wherein electrical conductors are passed through said hollow ring in the direction from a power supply unit, said computer system unit and an audio amplifier to said compressor, monitor, electric drives, electric valves, illuminating lamps and loud speakers.
