Abstract

L'invention concerne un intérieur (1) d'un soutien-gorge qui a pour effet de réduire le tremblement de la poitrine pendant un mouvement, c'est-à-dire qui présente d'excellentes propriétés antivibratoires, et un soutien-gorge (100) qui présente un excellent confort en plus des propriétés antivibratoires. L'intérieur (1) comprend une partie de recouvrement de buste (2) et une partie arrière (3) placée à partir des deux côtés de la partie de recouvrement de buste (2) par rapport à la surface arrière, la partie de recouvrement de buste (2) étant constituée d'un tissu dans lequel, lors d'un essai d'étirement répété à 50 %, la contrainte d'étirement à 50 % dans la direction horizontale de la partie de recouvrement de buste (2) est de 30 à 200 cN lors de la troisième répétition de l'essai.
