ABSTRACT:
A vehicle seat is provided with an elastic membrane which may be selectively tensioned by a bladder. In a preferred embodiment the frequency of the seat may be selectively modified by selective inflation of the bladder. The bladder also allows the membrane to be wrapped to a frame of the seat in such a manner to increase the predicted life cycle of the seat membrane utilized.
