Abstract: A seat suspension includes a seat support, a base, and a suspension assembly positioned between the seat support and the base. The suspension assembly includes a compressible cushion for containing a gas; and a chamber. The chamber includes a cylindrical hollow member, a front cap at one end of the cylindrical hollow member, an end cap at another end of the cylindrical hollow member, and a piston positioned within the cylindrical hollow member between the front cap and the end cap. The front cap includes an orifice. The orifice provides fluid communication between the cushion and the chamber. When a compressive force causes movement of the seat support portion towards the base, thereby compressing the cushion, the gas from the cushion flows through the orifice into the chamber and directly forces movement of the piston away from the front cap.

Abstract: A seat suspension for boats and other vehicles having a seat support, a base and a suspension assembly positioned between the seat support and the base and permits relative movement between the seat support and the base. The suspension assembly has a first fluid container, a second fluid container, and an orifice member positioned between the first and second fluid containers. The orifice member includes a first orifice in fluid communication with the first and second fluid containers. A piston is positioned within the second fluid container and movable by fluid flowing through the first orifice.
