Abstract:
1. A damping mechanism for foldable seats arranged in an articulated assembly which are movable between a horizontal use position and a vertical folded position, comprising: rotating shafts, which are each fixedly attached to the seat each rotating shaft having a spring arranged thereon which upwardly, radially tilts the seat towards the vertical folded position, wherein each rotating shaft has an eccentric radial cam with a variable radius rotating integrally with each shaft, and a damping piston supported on a periphery of the variable radius of the eccentric cam, the damping piston is arranged perpendicular to an axis of rotation of each shaft and exerts a retention action on the eccentric cam that smoothes the upward, radial tilting of the seat actuated by action of the springs.
