Abstract
A cushioning device including a first fluid bladder support structure having a first surface and an opposing second surface, a second fluid bladder support structure having a first surface and an opposing second surface, and at least one fluid accumulation reservoir. The first and second fluid bladder support structures deform under application of a load and reform upon removal of the load. A first conduit interconnects the first fluid bladder support structure in fluid communication with the second fluid bladder support structure. The first conduit includes a first one-way valve which permits fluid flow from the first fluid bladder support structure to the second fluid bladder support structure. A second conduit interconnects the second fluid bladder support structure in fluid communication with the at least one fluid accumulation reservoir. The second conduit includes a second one-way valve which permits fluid flow from the second fluid bladder support structure to the at least one fluid accumulation reservoir and which is a pressure relief valve. A third conduit interconnects the at least one fluid accumulation reservoir in fluid communication with the first fluid bladder support structure. The third conduit includes a third one-way valve which permits fluid flow from the at least one fluid accumulation reservoir to the first fluid bladder support structure.
