Development of a Comprehensive Criterion for Evaluating the Ergonomics Configuration of the Seat

The article is devoted to the development of a complex criterion for assessing the ergonomics of unsupported planting on the stool. The problems that lead to the violation of human posture are indicated. The issue of seat ergonomics is considered. The characteristic advantages of unsecured seats and their shortcomings are singled out. An analysis of ergonomics studies is presented for long-term sitting. The components for assessing the comfort of planting a person on a chair are determined. The integral criterion of a complex evaluation of seat ergonomics is formulated, which simultaneously takes into account the distribution of contact pressures and the location of the projection of the center of gravity of the body on the contact spot.
