Abstract
a. L'invention concerne un dispositif formant poste de liaison sans fil pour les communications dans les mines ou tunnels ne formant qu'un avec le casque protecteur porté obligatoirement. b. Le dispositif est caractérisé en ce qu'on monte dans et sur le casque, un cadre antenne, une partie récepteur et une partie émetteur reliées ensemble par un câblage et reliées aussi avec un microphone, un inverseur, des écouteurs et une source de courant. c. Ce dispositif permet d'assurer une grande sécurité sans surcharger l'équipement des travailleurs qui devront de toute façon porter un casque protecteur.
