SELF-ADJUSTING CUSHIONING DEVICE

摘要

A cushioning device (10) including a first fluid bladder support structure (12a) having a first surface and an opposing second surface, a second fluid bladder support structure (12b) having a first surface and an opposing second surface, and at least one fluid accumulation reservoir (14). A first conduit (24) interconnects the first bladder support structure (12a) in fluid communication with the second fluid bladder support structure (12b) and includes a first one-way valve (28a) which permits fluid flow from the first fluid bladder support structure (12a) to the second fluid bladder structure (12b). A second conduit (24) interconnects the second fluid bladder support structure (12b) in fluid communication with the at least one fluid accumulation reservoir (14) and includes a second one-way valve (28b) which permits fluid flow from the second fluid bladder support structure (12b) to the at least one fluid accumulation reservoir (14) and which is a pressure relief valve. A third conduit (30) interconnects the at least one fluid accumulation reservoir (14) in fluid communication with the first fluid bladder support structure (12a) and includes a third one-way valve (32) which permits fluid flow from the at least one fluid accumulation reservoir (14) to the first fluid bladder support structure (12a).
