Abstract

L'invention concerne un casque de protection, tel que pour motocyclistes ou skieurs, dont la coque 1 comporte une ligne d'amorce de rupture 3 occupée par une résistance chauffante filaire raccordée à des bornes latérales 4 pouvant être connectées à une source de courant électrique provoquant la fusion, au voisinage de la ligne 3, de la matiere constitutive de la coque, fusible en totalité ou uniquement dans la zone de ladite ligne 3. Le dispositif permet de fractionner la coque et de retirer facilement le casque de la tête d'un usager victime d'un accident sans risque d'aggraver les blessures de la tête.
