Description

Integrated ergonomic computer seat

Technical field

The present invention relates to the field of seat technology, and more particularly to an integrated ergonomic computer seat.

Background technique

As people's health requirements are getting higher and higher, ergonomics has been highly valued and developed at home and abroad. At the same time, computers are increasingly indispensable tools and partners for people's work and life. People's time has also brought more and more health problems. According to relevant surveys, more than 40% of white-collar workers suffer from computer syndrome, and the ergonomic equipment designed and configured for using computers is getting more and more affected. User's attention and welcome.

The use of computer-related ergonomic equipment can optimize the user's posture during the use of the computer and reduce damage to the body. The traditional ergonomic design focuses on improving the traditional computer control method and the equipment itself, paying more attention to the ergonomic characteristics and functions of the independent equipment itself, such as adding height and angle adjustment on the computer desk, using adjustable display Arms, keyboard stand and mouse stand, foot pedals to improve leg blood supply, and improved body structure, optimized design and more flexible fabrics on the computer seat to improve comfort and reduce physical damage to the user .

However, when using the independent, separately designed ergonomic equipment, the user cannot achieve better systemic ergonomic effects, such as the distance and position between the ergonomic computer desk and the display bracket and the computer seat. The user's posture is limited, and the adjustable keyboard bracket and the mouse bracket are not well matched with the seat, and the ergonomic equipment with excellent design principle cannot effectively exert its ergonomic effect during actual use.
