ABSTRACT:
The seat structure comprises a seat framework (2) and a backrest framework (6) which are pivotally interconnected by a pivot pin (4) which is movable in a substantially vertical curved opening (40). The framework of the backrest is extended by tabs (34) which are connected in their lower part by a link (32) to an element pivotally mounted on a pin (18) which is movable in a vertical opening (20). Owing to the fact that the pin (18) is carried by the seat, the adjustments in height and in inclination are strictly independent.
