Abstract

L'invention concerne, selon certains modes de réalisation, un dispositif de sécurité électronique à utiliser dans un casque pour un sport à impacts, qui est destiné à signaler à un premier utilisateur que la position de sa tête à l'intérieur du casque n'est pas sûre au moyen d'un corps raccordé à celle-ci. Dans certains modes de réalisation, c'est la tête du premier utilisateur qui s'avère être en position non sécurisée, auquel cas ce dernier est prévenu que la position de sa tête n'est pas sûre. En variante et/ou éventuellement, c'est la tête d'un deuxième utilisateur qui s'avère être en position non sécurisée, auquel cas le premier utilisateur est prévenu que la position de la tête du deuxième utilisateur n'est pas sûre. Dans des modes de réalisation très spécifiques, ledit dispositif de sécurité électronique comprend un capteur qui détecte la position de la tête et qui envoie des données correspondantes, et un processeur qui interprète les données du capteur afin de déterminer s'il est nécessaire de produire un signal indiquant que position de la tête n'est pas sûre.
