ABSTRACT:
The invention relates to a damping mechanism for folding seats in chairs, having an application in seats (1) incorporated in an articulated assembly by means of shafts (2), with springs (4) which act in the sense that they tilt the seat towards a vertical folded position, incorporating in each shaft (2) an eccentric cam (5) on which there is supported a damping piston which exerts retention action for smoothing the upward rotation of the seat by the action of the springs (4).
