Abstract: A bladder formed inside or positioned on a seat accounts for variations in personal anatomy with changes in the configurations of multiple chambers in the bladder and may also allow for changes to the constriction between the chambers in the bladder. The bladder forms a cushioning device that is used for seating applications which involve movement and continuously changes softness between the chambers by using the movement of the rider. Rider movement results in the interchange of pressures through variable-sized orifices between variable-displacement chambers. The number and size of the chambers can be varied according to a desired seating configuration. The orifice size can be changed with a variable constriction mechanism. Different fastening configurations can change the number and shape of the chambers. The cushioning device can be used in retrofitting existing seats and can be produced in new seats.
