Abstract
The invention relates to a method for monitoring a state of wear of a damping device within a system. The system includes a vehicle seat having a first portion which is movably mounted in at least one direction with respect to a second portion, a damping device for damping oscillations is arranged between the first portion and the second portion, and a first sensor that determines an instantaneous relative position of the first portion with respect to the second portion. A displacement function in relation to the relative position of the first portion with respect to the second portion is defined as a function of time, and a current value of the displacement function is determined at selected intervals and summed. The sum is compared with a predetermined first limit.
