ABSTRACT:
The subject pad comprises resilient layers attached to each other and spaced apart by compression members distributed with spaces between them. The compression members on one side of each layer are opposite the spaces between the compression members on the other side so that the layer portions between compression members of one layer function as beams loaded near or at their centers by compression members on the adjacent layers. The pad may be an integral part or the layers may be separate, in which case the compression members comprise mating projections from the surfaces of adjacent layers. The compression members may be ridges or colums. The projections may be shaped to mechanically interlock when mated, utilizing the resilience of the material and/or adhesive may be used to secure the attachment.
