Dynamic Suspension for Vehicle Seats

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> f_o √ 2.

Excitation frequencies of motor vehicles reach into the area f< f₁, the decrease of the effective frequency f_o 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.
