Base for an oscillating seat

A support base for a tilting seat, comprising:

• a coupling body provided with a rod seat for engagement with a piston rod of the tilting seat;
• a support body having a central portion provided with a passage with a main axis;
• a plurality of flexible components, structurally separable and elastically yielding, each flexible component of said plurality of flexible components being made in a single piece, the flexible components being circumferentially arranged around the coupling body, between the coupling body and the central portion, and configured to meet in compression according to oscillations of the piston rod,
• wherein each flexible component comprises a first elastically yielding block, a second elastically yielding block that is axially spaced apart from the first elastically yielding block, and a connection portion that connects said first and second elastically yielding blocks,
• wherein the central portion comprises a protrusion that projects radially internally in the passage or the coupling body comprises a flange that projects radially externally,
• wherein each flexible component is attached to the protrusion of the central portion or each flexible component is attached to the flange of the coupling body, and
• wherein the first elastically yielding block of each flexible component is arranged above the protrusion or the flange and the second elastically yielding block of each flexible component is arranged below the protrusion or the flange.
