ABSTRACT:
A furniture with a guide groove in each back leg for the purpose of folding up the furniture is provided with catch elements in the region of the guide groove. This makes it possible to adjust the seat at various inclinations with respect to the horizontal plane. According to a first embodiment a plurality of catch recesses are provided on one end of each guide groove. According to a second embodiment catch grooves are provided at one end of the guide groove which are substantially parallel to one another and extend at an obtuse angle from the guide groove. An adjustment means for a folding furniture comprises catch means provided in the region of one of the arm rests and protruding downwardly. The adjustment means operates together with an element which projects laterally in the region of a connection section between a front and back leg of the piece of folding furniture. According to a preferred embodiment of the invention, the catch means is provided in the form of a plate which contains catch recesses extending from a guide slot such that the element provided in the form of a journal can be engaged in various catch recesses.
