Abstract

L'invention concerne un dispositif d'isolation thermique en surface, en particulier, un vêtement ou une couverture pour le corps humain, caractérisé en ce qu'il comprend une enveloppe (2 ; 12) remplie d'un matériau thermo-isolant (3 ; 13), et en ce qu'il est prévu dans l'enveloppe (2 ; 12), au moins une sortie (32) permettant d'obtenir une réduction du volume gazeux dans le dispositif d'isolation. Le pouvoir isolant du dispositif peut ainsi varier, et en particulier, être réduit, par exemple d'un facteur 10, pour une réduction considérable de volume. On obtient ainsi un vêtement offrant, pour la personne qui le porte, une isolation thermique optimale, ceci lors d'activités sous des contraintes les plus diverses du corps humain.
