Abstract

L'invention concerne un casque avec un système d'ajustement réglable. Le casque comprend une coque de protection et le système d'ajustement réglable. Le système d'ajustement réglable est couplé à la coque de protection et positionné au moins partiellement à l'intérieur de celle-ci. Le système d'ajustement réglable comprend un cadre ayant deux points de fixation de cordon, un cordon couplé aux deux points de fixation de cordon du cadre et un dispositif de tension couplé de façon libérable au cordon entre les deux points de fixation. Le dispositif de mise sous tension est conçu pour ajuster une distance entre les deux points de fixation du cadre par l'intermédiaire du mouvement du dispositif de mise en tension par rapport au cordon afin d'ajuster une taille du système d'ajustement réglable. Le cordon peut passer à travers le dispositif de mise sous tension pour former une première partie entre chaque point de fixation de cordon et le dispositif de mise sous tension et une seconde partie en boucle s'étendant depuis le dispositif de mise sous tension à l'opposé de la première partie.
