Definitions

  • the present invention relates to a reclining support for backs, and in particular to a support which can be mounted onto reclining chairs or sofas.
  • Known reclining supports comprise upper and lower fixing members for fixing two portions of a back which can be reclined in a different and/or independent manner from each other.
  • the fixing members are generally mounted onto a fixed support by means of horizontal pins, so that each portion of the back can be manually rotated by the user.
  • these known supports have a poor comfort of use since they do not allow a smooth movement of all the portions of the back.
  • the support according to the present invention allows to rotate the two portions of the back with a smooth movement, especially if these articulated quadrilaterals are mutually connected by a horizontal shaft.
  • the horizontal shaft can be connected to the fixed supports by pulling elastic means, so as to facilitate the transformation from the upright position of the back to the reclined position, and vice versa.
  • Figures 1 to 3 show a reclining support 1, which comprises in a known way upper fixing members 2 and lower fixing members 3 which are provided with perforated plates for fixing two portions 4, 5 (partially shown with broken lines in figure 1) of a back.
  • the fixing members 2, 3 are pivoted to a horizontal shaft 6, in turn pivoted to a pair of fixed supports 7 through a pair of first levers 8 perpendicular to this shaft.
  • the fixed supports 7 can be fixed to the structure of a chair or a sofa.
  • a pair of second levers 9 are pivoted between the upper fixing members 2 and the fixed supports 7, while a pair of pulling elastic means, for example two springs 10, are fixed between the horizontal shaft 6 and the fixed supports 7, more precisely a pin 11 protruding inside each fixed support 7.
  • At least one of the two portions 4, 5 of the back can be inclined by pushing or pulling this portion, for example the upper portion 4.
  • the upper fixing members 2 thus rotate around the horizontal shaft 6, which is pushed forwards by the movement of a pair of articulated quadrilaterals made up of an upper fixing member 2, of a fixed support 7, of a first lever 8 and of a second lever 9.
  • This reclining movement of the back is opposed by springs 10 up to the overcoming of a deadlock, beyond which it is instead assisted. Therefore, for restoring the back in the upright position, it is sufficient to push or pull portion 4 of the back up to overcome said deadlock, after which springs 10 pull the horizontal shaft 6, thereby restoring the reclining support 1 to its initial position.
