(57) A chair with a backrest (3) and seat (4) which are movable in relation to a fixed
structure (2), consists of a backrest support (8) hinged to the fixed structure around
a first transverse axis (9) perpendicular to the vertical plane of symmetry of the
chair, the said axis being situated substantially at the seat level and being displaced
forwards in relation to the rear edge of the seat. Stop means are provided to limit
the rotation ofthe backrest support (8) relative to the fixed structure (2), the said
means defining a forwardly rotated end position forthe backrest support, corresponding
to an upright position of the backrest, and a rearwardly rotated end position corresponding
to a reclined position of the backrest. The chair is provided with resilient biassing
means which bias the backrest support (8) to its forwardly rotated end position. A
seat support (10) is hinged, substantially adjacent its front edge around a second
transverse axis (11) on the fixed structure (2) parallel to and displaced forwardly
relative to the first axis (9) the seat support (10) being also connected to the backrest
support (8) in correspondence with the rear edge of the seat.
