Abstract:
A pad for supporting a portion of the human body which forms an irregular surface configuration, the pad comprising two layers of substantially nonstretchable material joined together around a peripheral edge to define the pad, the layers being joined together at selected locations within an area bounded by the peripheral edge to form individual enclosed capsules within the area bounded by the peripheral edge, and a filling of a non-resilient, rheologically plastic conformable wax material only in the pad which will move slowly under repeated applications of force to assume configurations of a surface contacting and loading one of the layers of the pad and which retains the configurations when force is no longer applied, the selected locations being selected to restrain bulging of the material in the pad by separating the layers of material in regions that are lightly loaded, and the seams of the capsules preventing the wax material from moving from the capsule.
