US Patent 7624462 Load bearing or cushioning elements and method of manufacture

By providing an elongated profile which incorporates a plurality of indentations formed therein, a load bearing/cushioning/supporting element is realized. By employing this construction, the element accommodates large strain under force, and shows good resiliency and repeated recovery. The element can be produced from a continuous extrusion process with immediate manipulation to re-shape the extrusion profile, or secondary thermal forming process which follows the extrusion process, or blow molding process, or injection molding process.
