ABSTRACT:
A supporting or support plate arrangement for adjusting the inclination of at least one part of a repose surface of reclining furniture or the like, comprising two levers forming an articulated lever pair, one of the levers being constituted by a substantially U-shaped rack member provided with teeth at the leg edges and secured to a part of the reclining furniture. A slide member or slide is displaceable upon the toothed rack member and in which there is guided the end of a support lever member hingedly mounted at the second articulated lever of the lever pair. The aforementioned end of the support lever member engages between the legs of the U-shaped rack member and such end is guided in the slide member in such a manner that it is movable between a work position where it is in engagement with the teeth of the rack member and a rest position which permits the free displacement and rocking of the levers towards one another. A spring is provided between both articulated levers and/or a counterweight is provided at the second articulated lever, which strive to spread apart the articulated levers from one another. The free end of the second articulated lever possesses a support or contact surface for the part of the repose surface of the furniture which is adjustable in its inclination.
