Abstract
Abstract The present invention provides a vehicle seat with an elastic membrane which may be selectively tensioned by a bladder. In a preferred embodiment of the present invention 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.
