Abstract: The invention relates to improvements in the object of patent P200603269 for “Automatic rotation system for tilting seats of chairs or armchairs”, comprising rotation supports formed by two parts (1 and 2) which are rotating in relation to one another, between which there is incorporated a rotating draw-spring (4), one of the parts (2) of each rotating support determining an annular channel (5), in which there is housed a ring (6) together with a high-viscosity silicone filler, such that said ring (6) is linked by pulling with the other part (1) of the rotating support, a braking action occurring on the rotation movement between the two parts (1 and 2) due to the friction of that ring (6) with the silicone in the channel (5).

Abstract: A folding reading desk formed by a support structure with two boards, with an intermediate cavity in-between wherein a worktop board can be introduced and extracted, wherein said worktop board is coupled, in a sliding assembly with a braking system, to a board arranged in the mentioned intermediate cavity between the facing boards.

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).
