Abstract:
1. A device for recording vibrations transmitted from a vehicle to a person, the device comprising: a cushioned and sprung vehicle seat mounted in the vehicle; at least one detector unit for detecting vibration values, the detector unit being arranged on one of a vehicle seat frame or an associated component; an analysis unit for analyzing the detected vibration values and calculating vibration results for the vibration acting on a person using a preset transmission function based on the analysis; and at least one filter for filtering the vibration values based on filter values, which are based on differences between a first relationship of measured vibration values at a cushion surface of the cushioned vehicle seat to measured vibration values at a floor of the vehicle, which is in contact with the vehicle seat, and a second relationship of the vibration values detected to the vibration values measured at the vehicle floor.
