Abstract

A piece of furniture consisting of movable frame parts and a seat cushion articulated thereon and a rigidly fixed cushion element is so designed that it can be used in one working position as a chair and in the other working position as a kneeling chair. The change between the two positions takes place simply by folding down the seat cushion and the support fixed thereto.

Die beiden Tragelemente sind über diesen Kreuzungspunkt hinaus verlän­ gert, am freien Ende des einen Tragelements ist das Rücken- bzw. Knie-Polsterelement und am freien Ende des anderen Tragelements die Sitzfläche befestigt. Die beiden Tragele­ mente können in ihrer Neigung verstellt werden, wobei sich der Kreuzungspunkt verschiebt und die beiden möglichen Be­ nutzungsarten ergeben.

For this purpose, the seat surface 2 is pivotally mounted at a first pivot point 8 ( FIG. 2).

Die Umstellung zwischen den beiden Benutzungspositionen wird durch Umklappen einer Strebe 3 erreicht, deren eines Ende an der Sitzfläche 2 um einen zweiten Drehpunkt 9 beweg­ lich befestigt ist. Die Strebe 3 verhindert in der Sitzpo­ sition das Zuirückkippen des Möbels nach hinten. Dazu rastet die Strebe 3 in der Sitzposition mit einer Stelle 5 in ihrem mittleren Abschnitt an einem Anschlag 6 ein, der sich am Möbelgestell befindet.The changeover between the two use positions is achieved by folding down a strut 3 , one end of which is fastened to the seat surface 2 by a second pivot point 9 .
