This article deals with the definition of the optimal driver's seats properties on the examples of two systems with different kind of damping. In the first case use the springing support of driver seat uses a pneumatic spring and a telescopic hydraulic damper. In the second case, the damping effect is achieved by two pneumatic springs whose forces effect in the phase shifted by a throttle valve which is in the connecting piping system. The springing support driver’s seat issue is very serious and the effort grows by manufactures to optimize their dynamic properties. The main optimization criterion is vibration insulation efficiency with regard to health research and their associated health standards and regulations.
