(57) The invention relates to a device for adjusting and fixing the back (8) and the seat
(9) of an arm-chair, deck-chair or the like to a supporting structure (1) allowing
said back and seat to continuously reach different positions of reciprocal inclination
ranging between two end inclinations respectively corresponding to a minimum and a
maximum inciination.
in order to allow the user to vary the inclination between seat (9) and back (8) without
removing his bust from the supporting surface and with a very little effort, the back
(8) is supported and fixed in a rotary way around a horizontal axis (12) fixed with
respect to said supporting structure (1), the seat (9) is fixed to the back (8) by
means of hinges (10) and to the structure (1) by means of constraints (6) which support
the seat and allow the same to perform predetermined translation and/or rotation movements
compatible with the presence of said hinges and without solutions of continuity between
said end inclinations, and at least one of said constraints is braked.
