Abstract

Le problème à résoudre dans le cadre de la présente invention consiste à fournir un matériau de couverture pour membres inférieurs utilisable au sein et en dehors du cadre familial, car il concilie des aspects esthétiques et pratiques pour bien éliminer la sensation de fatigue de l’utilisateur et éviter le gonflement des membres inférieurs. La solution proposée consiste en un matériau de couverture pour membres inférieurs comprenant un motif formé par la disposition d’une pluralité d’éléments de pression de port (12 et 13) créant une sensation de pression sur le corps de l’utilisateur au niveau d’un tissu de vêtement flexible (11), le matériau se présentant sous forme d’une chaussette couvrant au moins la partie crurale du corps. Les éléments de pression (12 et 13) sont disposés dans les zones du matériau de couverture pour membres inférieurs correspondant à l’avant et l’arrière de la partie crurale du corps lorsque ledit matériau est ajusté au corps de l’utilisateur. Sur le côté avant de la partie crurale, la pluralité des éléments de pression (12) sont disposés à des intervalles dans le sens vertical et en diagonale de bas en haut à partir de la ligne médiane de la partie crurale jusqu’à ses deux côtés. Sur le côté arrière de la partie crurale, la pluralité des éléments de pression (13) sont disposés dans le sens vertical.
