Abstract

Abstract Translated from French Casque protecteur notamment pour cycliste ou cyclomotoriste. Il est essentiellement constitué par une calotte (1) thermoformée en matière synthétique comportant des dépressions telles que des alvéoles (2) ou des nervures (60) dont seules les extrémités opposées à celles qui sont solidaires de la calotte rentrent en contact avec le crâne de l'utilisateur, lesdites alvéoles constituent ainsi des absorbeurs d'énergie et déterminent entre elles des voies de circulation d'air pour le refroidissement de la tête. Application à la protection des cyclistes ou des cyclomotoristes. Protective helmet especially for cyclist or moped rider. It is essentially constituted by a thermoformed cap (1) made of synthetic material comprising depressions such as alveoli (2) or ribs (60) whose only ends opposite to those which are integral with the cap come into contact with the skull of the user, said cells thus constitute energy absorbers and determine between them air circulation paths for cooling the head. Application to the protection of cyclists or mopeds.
