The invention provides a vehicle seat construction and method of utilization of the same. The inventive vehicle seat construction alternately supports the vehicle seat occupant upon different portions of the vehicle occupant\s body. The above massaging effect relieves the vehicle seat occupant of possible discomfort realized after extended driving periods. Additionally, the inventive seat structure provides the alternating support feature while allowing the vehicle seat to function normally in the absence of the power to the pneumatic system which energizes the alternating suport feature.

A seat construction for supporting the occupant of a vehicle, said seat construction in combination comprising: a tri-leveled base having noncomingled first, second and third fluid passages for said respective levels, said first level having apertures for a controlled leakage; a plurality of first compliant cushion cells connected with said base for supporting said seat occupant away from said base, said first cells being placed adjacent said third level with a connection fitting allowing fluid communication between said first cell interior and first level; a second plurality of second cushion cells for supporting said seat occupant away from said base independently from said first cushion cells, said second cells being substantially identical to said first cushion cells locationally intermingled with said first cushion cells in a set pattern and being adjacent said third level with connecting fitting allowing fluid communication with said second level; and an air permeable pad for supporting said seat occupant above said first and second cells; means to alternately create a pressure differential between said first and second level cells by applying pressurized air to one of said levels and a vacuum to said other cushion levels whereby said seat occupant is alternately supported away from said base along different locations of said seat occupant and means to supply pressurized air to said third level.
