Abstract
The invention relates to a seat comprising a lower frame which is placed on the floor (1) and on which a synchronous mechanism (2) is mounted. A horizontal fixed main rotational axle (D1) and a horizontal secondary rotational axle (D2) that can be pivoted about the main rotational axle (D1) are arranged on the synchronous mechanism (2). Said synchronous mechanism (2) also comprises a fixed base (20) which is to be placed on the lower frame (1) and penetrated by the main rotational axle (D1). A pivotable seat carrier (21) for fixing the seat element (3) is arranged above the base (20) and is penetrated by the secondary rotational axle (D2). First connecting means (22) are fixed to the main rotational axle (D1) and the secondary rotational axle (D2) in an articulated manner. Second connecting means (23) are provided opposite the secondary rotational axle (D2) as a connection between the base (20) and the seat carrier (21). A backrest (4) is fixed to the synchronous mechanism (2), said backrest being pivotable about the fixed main rotational axle (D1) against the resistance of a spring module (24). The movements of the seat (3) and the backrest (4) are mutually synchronised.
