Ergonomic computer chair

摘要

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.
