Abstract

L'invention (voir la figure 1) porte sur un protecteur de torse universel à usage sportif, pourvu de systèmes hydropneumatiques d'absorption des chocs et de refroidissement de l'épiderme. Les réalisations selon cette invention offrent une protection du torse, comme stipulé par la Directive européenne 89/686/EEC relative aux équipements individuels de protection, (PPEs) de la catégorie II. Cette protection est assurée grâce à une structure porteuse à base de plastique solide ou de fibres de carbone, à un système d'absorption des chocs, constitué de matelassages renforcés de densités et d'épaisseurs variées, et à un dispositif auxiliaire hydropneumatique d'absorption des chocs (figures 8, 13 et 14). Ce dernier fait intervenir des éléments disposés dans les matelassages renforcés ou dans des vêtements à porter séparément. A la différence des ensembles protecteurs de torse classiques du commerce, le protecteur selon l'invention procure un certain confort physique du fait de la présence d'un système de refroidissement de l'épiderme utilisant les éléments et composants d'habillement suivants: élément chimique de refroidissement obtenu par la solubilisation commandée de pastilles de nitrate d'ammonium (figure 10), élément dissipateur thermique comportant des matériaux de refroidissement par accumulation thermique (substances glycoliques gélatineuses) (figure 10), élément de refroidissement électrique avec organes de ventilation (figure 11), élément de refroidissement électronique avec modules à effet Peltier (figure 11), élément de refroidissement par atomisation avec libération de gaz comprimé par des bouteilles normalisées (figure 12), gilet porté à même la peau, doté d'éléments de refroidissement obtenus par la solubilisation commandée de pastilles de nitrate d'ammonium (figure 13), maillot refroidisseur porté à même la peau comportant des matériaux de refroidissement par accumulation thermique (substances glycoliques gélatineuses) (figure 14). On utilise les cinq éléments lorsque le protecteur est porté à même la peau et les deux vêtements lorsque le protecteur n'est pas en contact avec la peau.
