An adaptive, energy absorbing body (10) includes a plurality of fluid filled cells (12) joined together by fluid flow passageways (22) so as to establish an intercommunicating structure which provides effective cushioning. The cells (12) also include pressure responsive seals (30) which restrict fluid flow between the cells (12) and when the cells (12) are subjected to a mechanical force above a preselected level. Closure of the seals (30) converts the material from open cell, to a closed cell structure, allowing it to absorb and dissipate high levels of kinetic energy. The structure is particularly useful as a shock absorbing element for footwear.
Corps adaptatif absorbant l'énergie (10), comprenant une pluralité de cellules remplies de fluide (12) reliées entre elles par des conduits d'écoulement de fluide (22), de manière à constituer une structure communicante à amortissement efficace. Les cellules (12) comportent des obturateurs réagissant à la pression (30), qui limitent l'écoulement intercellulaire, lorsque ces cellules (12) subissent une force mécanique dépassant un seuil préétabli. La fermeture des obturateurs (30) transforme le matériau à cellules ouvertes en une structure à cellules closes, lui permettant d'absorber et de dissiper des niveaux élevés d'énergie cinétique. La structure est particulièrement utile comme amortisseur de chocs dans les chaussures.
