Abstract
In order to achieve the necessary flexible curve according to the natural curve of the human spine in the field of back supports, the back support, attached relatively rigidly in its lower section to the seat, is constructed increasingly more flexibly towards the top. So that the desired course of the spine-like curve can also be achieved at the upper end of the shoulder pad connected to the back rest when the chair is 'loaded', a spring member which becomes progressively 'harder' is mounted in the connecting element between the end of the back rest and the shoulder pad.
