Abstract

TITRE DE L’INVENTION : DISPOSITIF DE RÉDUCTION DE BRUIT ET D’IDENTIFICATION POUR CASQUE DE PROTECTION ACOUSTIQUE Le dispositif (25) de réduction de bruit et d’identification s’adapte à un casque (10) de protection acoustique prédéterminé comportant deux coques (15) reliées entre elles par l’intermédiaire de liaisons mécaniques (36) montées, sur chaque coque de manière amovible en extrémité de deux arbres (12) cylindriques d’axes colinéaires. Le dispositif comporte une enveloppe (25) en matière élastique de forme intérieure épousant une partie de la forme extérieure d’au moins une des coques, ladite enveloppe présentant :- des ouvertures (24) correspondant aux arbres et- autour de ces ouvertures, une épaisseur inférieure à la distance entre la liaison mécanique montée sur une coque et ladite coque. La matière élastique constituant l’enveloppe a un coefficient d’élasticité tel que la déformation de l’enveloppe nécessaire pour que l’ouverture correspondant à un arbre s’écarte suffisamment de la coque pour que cet arbre sorte intégralement de cette ouverture, soit réversible. Figure pour l’abrégé : Figure 10.
