The paper shows some possibilities of pneumatic springs and their mechanical and pneumatic connections in the resilient supports. The characteristics of the supports are available in many systems of technical praxis as well as by driver seats, ambulance couchettes, etc. The pneumatic springs provide the adaption of the stiffness, and here with the adaption of the natural frequency of the system to its exciting frequency. In cases of the application of the object vibration isolation, they can change the load characteristics in a relative large range and the effect is powerful. The change of the stiffness can be executed during the movement of the object, and thereby the behavior of the load characteristic ofthe spring suport becomes a hysteresis. This signals that the system is damped, and this influence on the oscillating system is positive in most vibration isolation cases.
