Description

An ergonomic chair test bench

technical field

The utility model relates to an ergonomic seat experiment platform.

Background technique

Ergonomics research on seats often requires measuring physiological data or recording subjective experience of people in a certain sitting posture. Currently, two methods are mainly used: (1) Relying on physical objects (seats or benches) for sitting posture research; ( 2) Use parametric software to construct 2D/3D models, and conduct computer simulation research on sitting postures. The latter ultimately depends on the experimental data and results provided by the former. Although the cost of using physical seats for ergonomics measurement is low and the implementation is convenient, it is impossible to quantitatively adjust the shape of the seat and obtain continuous and controllable experimental data. It can be seen that it is of great significance to construct a test bench that can provide multi-posture sitting posture simulation.
