Piece of furniture

Claim 1

A piece of furniture, comprising: a stand a seat, a back support pivotable with respect to said seat, and an upwardly and downwardly pivotable leg support provided with a foot-rest; at least one operating means pivotably connected with said seat and said support for movement thereof backwardly from a sitting position, in which the feet of a user are resting on said foot-rest, and for a simultaneous pivoting of said leg support upwardly and forwardly to cause a relative movement between said foot-rest and said seat such that knee-adjacent leg portions of the user remain in supporting contact with the supporting areas of the piece of furniture; said seat being movably arranged in a direction forwardly and backwardly relative said stand through pivoting of said back support; said leg support being pivotably connected to said stand about a pivot axis fixed with respect to said stand for all movements relative to said stand, said foot-rest being located at a constant distance from said pivot axis during the pivoting of said leg support upwardly and downwardly; said operating means upon pivoting of said leg support upwardly and forwardly imparting movement of the seat in a direction backwardly relative to said stand and thereby relative to said pivot axis of said leg support, and said operating means comprising at least one link extending between a point on said seat and a point on said back support; an intermediate part having a first part pivotally hinged through a front hinge to said seat and a second part pivotally hinged through a second hinge to said back support for pivoting of said back support; power means associated with said intermediate part through said seat for pivoting said support in response to said seat imparting movement to said intermediate part; said back support having first and second portions, said first portion being connected to said intermediate part about said second hinge so that said first portion extends outwardly from said second hinge, and when said back support is from said second hinge, and when said back support is pivoted to a normal sitting position said first portion extends upwardly and substantially forms the real back supporting part of the back support, and said second portion extends downwardly; means associated with at least one of said intermediate part and said back support for limiting the pivoting of said first portion of said back support backwardly relative to said intermediate part; and said link being to said second portion of said back support, wherein said first portion of said back support is arranged to, at the backward pivoting of said back support, enter into supporting engagement with a portion of said stand in such a way that continued influence by said power means on said intermediate part for pivoting thereof in the direction backwardly gives rise to pivoting of said back support relative to said intermediate part so that said first portion of said back support is pivoted upwardly and so that said second portion of said back support is moved at least one of backwardly and downwardly and thereby via said link actuates the seat in the backward direction.
