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.

L'invention concerne un élément de support de charge/amortissement/support obtenu par formation d'un profil allongé incorporant une pluralité d'empreintes. Cette construction permet à l'élément de supporter une forte contrainte sous la force, et de présenter une bonne élasticité et une bonne capacité de récupération répétée. L'élément peut être obtenu au moyen d'un procédé d'extrusion en continu avec une manipulation intermédiaire pour reformer le profil d'extrusion, ou un procédé de formation thermique secondaire suivant le processus d'extrusion, ou un procédé de moulage par soufflage, ou un procédé de moulage par injection.
