FIELD: automotive industry.
SUBSTANCE: invention relates to vehicle seat suspensions. Seat suspension comprises helical spring, hydraulic damper and pneumatic system separately arranged between the base and upper pair of plates. Aforesaid pneumatic system comprises an active element representing a double-action pneumatic cylinder, control element, electropneumatic valves, pneumatic lines, vibration-and-position electronic pickups, electronic control unit and receiver. Aforesaid control element represents electropneumatic transducers. Depending upon the strength of signal coming from the vibration-and-position electronic pickup, aforesaid transducer adjusts the pressure of air forced into pneumatic cylinder working chambers.
EFFECT: higher efficiency of seat vertical oscillation damping.
