<p>The invention regards an adjustment device for a chair for office use, of the type with so-called "synchro" movement, i.e. with simultaneous, synchronised tilting of the seat (S1) and the back (S2). Such chair is provided with an elastic damper (C) and a support column (P). Said device is characterised in that it substantially has three elements, i.e. a V-shaped fork, an L-shaped frame and a plate, mutually hinged, so to make a very simple, articulated structure which allows the "synchro" movement as well as the tilting of only the seat and where the entire mechanism constitutes the seat and the attachment of the two arms and the frame.</p> |
