Abstract
A seat carrier and a back rest carrier are linked by pivot joints through a lever to a carrying or swivelling component. At the end of the seat carrier on the back rest side there is connected a chain of link members which at its other end is connected to a slide and a back rest. When the chair inclines towards the rear, the chain of link members causes the slide and the back rest to conjointly move in a downwards direction. The so-called undressing effect caused by the change-over from the normal position into the rearwardly inclined position of the back rest is eliminated in a simple and space saving manner and without exploiting the space below the seat carrier. By arranging a spring element, for instance a gas spring, in the knee region of the chair, ready access can be had to the spring element for arresting it.
