Operator Seat Design Problems in Reference to Theoretical Vibration Isolation and Practical European Recommendations

A short survey of the literature about human tolerance to vibrations and about seat transmissibility is presented. A brief summary of European regulations concerning seat characteristics will include not only vibration absorption requirements but also recommended dimensions and necessary adjustments. Safety rules as issued in some countries, in particular for tractor seats, are also discussed.

The practical problem of making a seat in accordance with all these factors at a reasonable cost with durability and easy adaptation to the unskilled user will be discussed as a compromise. Conventional systems and new trends are briefly indicated.
