<p>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 of the backrest support (8) relative to the fixed structure (2), the said means defining a forwardly rotated end position for the 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.</p> |
