Ergonomic chair

Abstract

An improved ergonomic chair, including a chair base, a chair cushion and a chair back located to the rear of the chair base. Support strength of cushion pads on the chair back assumes a fan-shape extending from a lower end towards the upper end, thereby dispersing the compressive stress on the lower back and supporting the back of a person. A support cushion is located on the chair back corresponding to the cervical vertebra of a person, and a head cushion, provided with a plurality of depressions, is located on the chair back above the support cushion. Accordingly, the design of the support cushion and the head cushion facilitating the dispersal of the compressive stress on the lower back and support of the back and cervical vertebra provide the chair back with the ability to appropriately support the cervical vertebra, thereby enabling neck pains to be avoided when sitting.

Description

BACKGROUND OF THE INVENTION[0001](a) Field of the Invention[0002]The present invention relates to an improved ergonomic chair, and more particularly to an ergonomic chair which enables a chair back to appropriately support the cervical vertebra, and thereby avoid neck pains when sitting.[0003](b) Description of the Prior Art[0004]Chairs of the prior art are usually structured from a chair base, a chair cushion and a chair back, wherein the chair cushion is disposed on the chair base, and the chair back is joined to the chair cushion at an appropriate angle of inclination, thereby enabling the back of the user to lean against the chair back when sitting on the chair cushion.[0005]However, chair backs of chairs of the prior art are unable to effectively support the cervical vertebra, resulting in poor head postures when sitting, thereby causing pressure on the peripheral nerves of the cervical vertebra when sitting or sleeping on chairs of the prior art for long periods of time and af...

AI Technical Summary

Benefits of technology

"The present invention provides an improved ergonomic chair that can help prevent neck pains when sitting. The chair has a support cushion on the back that appropriately supports the cervical vertebra, while the head cushion provides support for the rear portion of the head. The design of the support cushion and head cushion facilitates the dispersal of compressive stress on the lower part of the trunk and supports the cervical vertebra, regardless of how the user changes sitting posture. The chair back is fitted with a protruding support cushion that supports the cervical vertebra, and a head cushion with equally spaced depressions that provide support for the rear portion of the head. The design of the support cushion and head cushion allows the chair back to appropriately support the cervical vertebra and avoid neck pains."

Problems solved by technology

However, chair backs of chairs of the prior art are unable to effectively support the cervical vertebra, resulting in poor head postures when sitting, thereby causing pressure on the peripheral nerves of the cervical vertebra when sitting or sleeping on chairs of the prior art for long periods of time and affecting development of the central nervous system.
