Description

technical field [0001] The invention relates to an office swivel chair, in particular to an anti-rollover swivel chair. Background technique [0002] In recent years, more and more people regard swivel chairs as the first choice for configuration, no matter in the office or in the family. Compared with traditional chairs, swivel chairs have the obvious feature that they can be divided into three parts: cushion, support shaft and base. The gravity above the cushion part is only transmitted to the base through the support shaft. This structure has just caused the swivel chair to be not as stable as the traditional chair in terms of mechanics, and the problem of rollover is prone to occur when people sit on the swivel chair to stretch their bodies or pick up things sideways. Existing swivel chairs lack a rollover reminder device, causing users to be easily injured due to the rollover problem, and the safety is low. In addition, the connection between the universal wheels and ...

AI Technical Summary

Problems solved by technology

This structure leads to the fact that the swivel chair is not as stable as the traditional chair in terms of mechanics. When people sit on the swivel chair to stretch their bodies or pick up things sideways, they are prone to rollover problems.

Existing swivel chairs lack a rollover reminder device, causing users to be easily injured due to rollover, and the safety is low

In addition, the connection between the universal wheels and the base of the existing swivel chairs is rigid, and the cushioning performance of the chair is only realized by the softness of the cushion, which lacks vibration-absorbing ability, resulting in poor comfort of the chair

Therefore, existing swivel chairs have the problems of poor safety and comfort
