Seat structure, particularly for bicycle, having a customizable shock absorbing element between the shell

A seat structure with controlled and customizable elasticity, particularly for vehicles, designed to be connected to a movable or stationary frame, comprising:

• a support element having a bottom surface and a top surface for supporting at least partly a user;
• a cover element, designed to contact at least partly the user, associable to said support element at the top surface of said support element;
• a connection member associable to said support element for anchorage thereof to said movable or stationary frame;
• and
• at least one shock absorbing element, which is designed to absorb shocks and vibrations transmitted from said frame to said support element, said shock absorbing element comprising:
• a body made of a first elastic material and located between the bottom surface of said support element and said connection member, said body having at least one seat;
• and
• an insert suitable to be placed in said at least one seat of said body, said insert being made of a second elastic material to control and selectively adjust overall elasticity of said shock absorbing element;
• wherein at least one aperture is formed in said support element at a same position as said at least one seat for insertion of said insert, said aperture being accessible from outside of the seat structure after removal of said cover element.
