Abstract

L'invention concerne un vêtement ergonomique, utilisé notamment pour le sport et les loisirs. Il comprend une structure de base (2) au moins en partie formée d'un tissu de fibres naturelles ou synthétiques, et au moins un élément protecteur (3), fermement attaché à la structure de base sur une surface de contact (6). L'élément protecteur (3) comporte au moins une couche viscoélastique. Le matériau viscoélastique de l'élément protecteur (3) pénètre au moins en partie dans le tissu de la structure de base (2) tout en ne s'étendant pas au-delà de sa face externe (4) ou de sa face interne (5), selon le cas, afin de former un assemblage monolithique par liaison chimique et/ou mécanique sur la surface de contact (6). Le matériau viscoélastique est de préférence un gel de polyuréthanne ayant une forme définie. L'invention concerne également un procédé de fabrication dudit vêtement.
