Human engineering seat

Abstract

The invention provides a human engineering seat. The human engineering seat comprises a base supporting frame, a back plate and displacement adjustment mechanisms, wherein a seat pate is connected with the base supporting frame; the back plate is pivoted with the base supporting frame; a connecting rod mechanism capable of adjusting the angle of the back plate is connected with a position between the back plate and the base supporting frame; the displacement adjustment mechanisms are respectively connected with the seat plate and the back plate. The human engineering seat can enable the back, pelvis, coccygeal vertebra and lumbar vertebra muscles of a user to be in tight contact with the seat during use, so that the user keeps a stable sitting posture, and the feeling of fatigue and the feeling of numb and ache of the user seating in the seat for a long time can be reduced; in addition, the human engineering seat can further gather sitting postures and sitting shapes of different human bodies, stress of different skeletons of people after sitting, and deformation situations of the back and the seat surface of the seat.

Description

technical field [0001] The invention relates to a seat, in particular to an ergonomic seat for testing the stress state of the back and buttocks of a human body and having the function of an ordinary seat. Background technique [0002] Chairs are an indispensable tool in our daily life. According to the British "Guardian" report, as many as 59% of the world's laborers need to sit in the office all day to work. These sedentary people maintain a sitting posture for a long time. When the spine cannot get the necessary support, the waist of the human body will cause the load on the intervertebral discs, vertebrae and tendons due to long-term bowing, which will lead to chronic muscle fatigue, resulting in acid Pain; if the pressure of the intervertebral disc is too high, it will easily lead to disc herniation; if the nerve is compressed, it will easily cause numbness. These problems have brought great troubles to office workers or sedentary people. [0003] In order to solve the...

AI Technical Summary

Problems solved by technology

However, its shortcoming is that these studies are still in a two-dimensional research state on the whole. When a person sits on a seat, the seat cannot produce close contact with the buttocks, pelvis, coccyx and lumbar muscles of the human body. connection, which creates a sense of instability and fatigue

Therefore, this type of chair cannot well satisfy people's needs for comfort when the seat is actually used to a certain extent.
