Analogic seat carrier mechanism with back movement controlled by pressure applied on the base

摘要

he mechanism in question is practicable for office chairs, which are responsive to the needs of working persons frequently changing their posture while working. The present mechanism supports discreetly all the postures of a working person whose movements (e.g. normal position, stretching or retraction of the feet) burdens the front part of the seat portion. The pressure of these movements exerted on the seat portion is received by said mechanism permitting the execution of the different movements of the body.
