Dynamic Suspension for Vehicle Seats 785127

Presently utilized flexible suspension systems for motor vehicle seats are characterized by:
- positions of minimum potential around which small oscillations are produced.
- distinct spectrum values.
The dynamic response of these systems is of a type where transmissibility in displacement approaches sub-unity only in the area of over-resonance for f1> fo √ 2.
Excitation frequencies of motor vehicles reach into the area f< f1, the decrease of the effective frequency fo being constructively limited by the travel of the seat.
A dynamic suspension proposed by the authors would realize a reduction in the effective frequency approaching zero.
