Abstract A seat occupant-activated underseat support air-cushion consisting of: a support base, an airtight expandable aircushion, resting in the support base, with the top of the air-cushion pressing upward against the bottom side of the vehicle seat cushion, with an air pump or pumps, disposed within, air-cushion which is provided with outside air-intake or intakes, air pump or air pumps arranged within to be normally expanded, filled with air on the beginning of the air pumps compression stroke in a manner so that any downward pressure by the seat occupant's weight would cause the pump or pumps to compress air, discharging it thru the pumps check valve into the air-cushion. Air-cushion to be equipped with an adjustable automatic air pressure regulating valve, discharging surplus air to exterior of air-cushion. Thus providing the seat occupant with an air-cushion ride, the constant motion of the moving vehicle to provide a continuing source of energy to operate the air-cushion.
An occupant-activated underseat support air-cushion, comprising: a support base means, an air-cushion resting on said support base means and having an air-pump inflation means contained therein, said air-pump inflation means having a one-way inlet from a source means exterior the air-cushion and a one-way outlet extending into the air-cushion, said air-pump inflation means activated by the weight of an occupant riding on said seat such that a downward force causes the air-pump inflation means to expel air into the air-cushion thereby increasing the pressure therein so as to counter-act the downward force; said air-cushion further having an adjustable air-regulating means therein to enable an occupant to selectively adjust the pressure within said air-cushion.
