Definitions

  • the invention relates to a chair with synchronized variable tilt seat and backrest.
  • a chair or armchair of the aforementioned type which comprises articulation means between the seat and back supports, particularly simple and efficient, these supports, although they are separated, being placed one in continuation to the other without a solution of continuity, this condition being preserved in any position of inclination of the seat and the backrest.
  • the invention relates to a chair or armchair with seat and backrest with variable inclination according to claim 1.
  • the chair or armchair according to the invention comprises a base - not shown - which carries a fixed device or upright (10) or preferably adjustable in height, a body (11) fixed to the top of the device or upright (10), a support (12) for the seat (13) and a support (14) for the backrest (15).
  • the seat support and also that of the backrest are both articulated to the fixed body (11 and connected together by a synchronization connector (16) also articulated to the above-mentioned fixed body.
  • the seat and back supports can thus define a support surface that is substantially free of continuity.
  • the support (12) of the seat is articulated, in its intermediate part, to the fixed body (11) by means of an elastic or oscillating element (17), while the rear part of the support (12) is fixed to a flange (18) pivoting or oscillating on the connector (16) by means of a pin (19).
  • the connector (16) is mounted by means of an oscillation pivot (20) on the fixed support (11) in a position moved forward relative to the pin (19) of the flange (18) which carries the support of the seat, and precisely in an intermediate position diaire between the pin (19) and the elastic or oscillating element (17) which supports the support (12) of the seat.
  • the support (14) of the backrest is mounted on the fixed body (11) by means of a pivot (21) placed in a position between the oscillation pivot (20) of the connector (16) and the pin (19) of the flange (18).
  • the support (14) of the backrest is provided with lateral pins (22) for its assembly to the connector (16) at some distance from the pivots (19, 20 and 21), these pins engaging a slot (23) cut in the connector (16).
  • the pivots (19, 20, 22) which articulate the connector synchronization (16) respectively to the support (12) of the seat, to the fixed body (11) and to the support (14) of the backrest are located at the vertices of a triangle, the pivot (20) being fixed, while the others two (19, 22) are mobile.
  • the pivot (21) for the articulation of the support (14) of the backrest to the fixed body (11) is placed inside the triangle (19, 20, 22), while the contrast gas spring (25) is connected in (24) to support the file outside this triangle.
  • each oscillation or rotation of the support (12) of the seat on its elastic or oscillating support element (17) is automatically transmitted to the support (14) of the backrest through the connector (16) for a correlative variation of the inclination of the two seat-backrest elements.
  • the same thing is obviously verified following a push applied to the backrest and angularly moving it around the pivot (21) of its support (14).
  • the displacements are synchronized and contrasted by the gas spring (25) and by the additional spring means - not shown - which tend to recover the initial position of the components after the action which has not caused the variation of the inclination is stopped.
