Definitions

  • the subject of the invention is a sofa that, with a simple structure and simple maneuvering, varies the arrangement between the seat and the back with arms, thereby providing considerable advantages over currently known solutions.
  • EP-A-1118295 shows a sofa in which the back and the arms can be moved with respect to the seat by means of complex structures and sliding systems within tubular elements of a base frame.
  • the back is articulated to said structure so as to assume several differently inclined arrangements, independently of said positions assumed by the structure.
  • the back may consist of at least two sections that can be adjusted independently.
  • 1 is the general reference given to a seat with a support frame 1A and an elastic thickness 1B, that can be produced in one of the ways technically known for this purpose.
  • the seat 1 is fixed with respect to the upper part comprising the arms and back, which is movable.
  • This upper part is in the form of a horizontal U-shaped structure comprising the two arms 3 and an intermediate part to which are articulated to back sections 5.
  • lever arms 7 and 9 hinged to the frame 1A at 10 and 12 respectively, and curved in two opposite directions for esthetic purposes, are articulated to each end of the frame 1A of the seat 1.
  • These two lever arms 7 and 9 form part of a parallelogram linkage formed at each arm 3 and comprising extensions 7A and 9A together with a horizontal lower part 14 articulated to said extnesions, and upper articulations 16 and 18 for articulation to the U-shaped structure 20 of the arms.
  • This arm structure 20 comprises a stiffening bar 22 and also, at the articulations 16, another bar 24 able to rotate around its own axis. This bar 24 bears the frame 26 of the two back sections 5.
  • the bar 22 has, in an intermediate position between the two lever arms 7, a lever arm 27 for engaging the oscillating bar 24 in an intermediate position between the two back sections 5.
  • the curve of the lever arms 7 and 9 and of the intermediate lever arm 27 have been designed to be concealed as far as possible in the two arrangements that the components of the sofa 1, 3, 5 can assume, as seen in particular in Figures 5 and 6 .
  • the intermediate lever 27 does not require such guidance, and extends in the slot formed between the two seat cushions.
  • Each of the back sections 5 may be adjusted in inclination, from an arrangement in which it is completely horizontal and coplanar with the arms 3 to arrangements in which it is inclined to a greater or lesser degree, as required. This is achieved by adjustment mechanisms of the type known per se and generically indicated with the number 34. Such mechanisms generally work by raising the back section in successive increments, which can be cancelled out by bringing it all the way into the vertical position, after which the back section can be folded down into the position in which it is coplanar with the arms.
  • the arms may stay slightly raised from the surface of the seat, both in the forward position of Figures 1 and 5 and in the other position of maximum separation from the front part of the seat, as shown in Figures 2 and 6 .
  • the guide slots 32 may have an appropriate coating, as may the lever arms 7 and 9 that slide in said slots 32.
  • the metal components of the various frames will be made in such a manner as to ensure maximum stiffness and also to provide the stops needed by the parallelogram linkage systems so as to cause the arms and the back sections to take up one or other of the two positions, forward or pushed back.
