Abstract

Un caleçon de sport (1) comprend un tissu principal extensible (2a, 2b, 2c) permettant de recouvrir la partie allant de la région lombaire jusqu'au moins au-dessus du genou, est porté de façon à être sensiblement en contact étroit avec le corps, et comprend une partie de renforcement A (4a, 4b) et une partie de renforcement B (5a, 5b), la partie de renforcement A se trouvant dans la région sous la ligne s'étendant dans la direction latérale à partir d'une partie d'entrejambe avant du tissu principal (2a, 2b) et au-dessus du genou, et la partie de renforcement B se trouvant dans la région le long d'une partie interne de la cuisse. Les parties de renforcement A et B peuvent être formées par adhérence, avec un adhésif, d'un morceau du tissu principal ou d'un morceau de tissu différent du tissu principal, sur la surface arrière ou la surface avant du tissu principal. L'invention concerne donc un caleçon de sport pouvant supprimer les vibrations musculaires afin d'améliorer les performances athlétiques et de conserver une bonne sensation de porté.
