A device together with an assigned working machine for decoupling vibrations between two systems (2, 4) in the form of spring-mass oscillators, of which one system (2) is assigned to a motion machine and the other system (4) is assigned to an operator operating the motion machine. The other system (4) at least partially performs motions about a transverse axis (Q) during driving motions of the motion machine and in doing so is subject to vertical motions in the direction of a vertical axis (z) at an absolute vertical speed (v.sub.z1,1) serving as an input variable of control devices and/or regulating devices. Those devices control a damping system (8) of the one system (2) and/or the other system (4) to compensate for the vibrations. The respective pitch motion of the other system (4) is detected by at least one rotation rate sensor. The respective measured value (ω.sub.1) of the sensor, preferably amplified by only a predeterminable factor (L.sub.1), results in the absolute vertical speed (v.sub.z1,1) as input variable.
