AI Technical Summary

Technical Problem

Existing office chairs cannot keep up with the user's body tilting left and right, resulting in a lack of lumbar support, poor support fit, and fatigue after prolonged use.

Method used

Design an office chair with an adaptive comfort adjustment structure. By setting a lumbar support component and an elastic support component on the main body of the chair back, including a lumbar support component with torsion springs and tension springs, and setting deformation texture on the main body of the chair back, the chair back can achieve synchronous deflection and adaptive adjustment, provide reverse elastic support force, and adapt to lumbar support for different sitting postures.

Benefits of technology

The main body of the chair back can rotate synchronously with the user's movements, maintaining a close fit and support to the human back, improving the support and fit in the full sitting position, relieving lumbar fatigue, and improving comfort.

Abstract

The invention discloses an office chair with a self-adaptive comfort adjusting structure. The office chair comprises a chair seat main body, a chair back main body, a waist chasing assembly and a chair back elastic supporting assembly. The bottom end of the chair back main body is connected to the chair seat main body in a sliding manner. The waist chasing assembly is used for providing reverse elastic supporting force for the waist area of the chair back main body, so that the supporting position of the waist area of the chair back main body is adjusted in a self-adaptive manner. The chair back elastic supporting assembly is arranged, the back-chasing elastic pieces in the chair back elastic supporting assembly can elastically support the left side and the right side of the chair back body, when a user inclines the body left and right to adjust the sitting posture, the chair back body synchronously deflects along with the action of the user, and the back-chasing elastic pieces synchronously correspondingly deform; the fit supporting state of the chair back main body and the back of the human body is always kept, the problem of support disjunction of the chair back main body is avoided, the fit degree in a full sitting posture state is effectively improved, and the waist fatigue feeling is reduced.
