CA 2159458

A method of providing a helmet shell or like structure, particularly a face mask for ice-hockey goal tenders, with an impact-absorbing padding while adapting the shape of the padding to the individual shape of the wearer's head. According to the method, a padding blank is first cut from a sheet of thermoplastic material of suitable hardness and the blank is heated to a temperature at which it softens so as to become easily shaped. The blank is then placed in the helmet shell and the shell is placed on the head of the intended wearer and pressed down against the head with a force sufficient for the blank to be brought to the shape of the head and of the helmet shell. This force is maintained until the blank cools to a temperature at which the material retains its shape whereafter the padding is affixed to the helmet shell with the aid of fastening means applied to the helmet shell and/or the padding. The invention also relates to a helmet provided with padding that has been shaped in accordance with this method.

Procédé permettant d'équiper d'une doublure amortissante un casque ou analogue, notamment un masque protecteur facial pour gardien de but de hockey sur glace, et simultanément d'adapter la forme de la doublure à celle de la tête de l'utilisateur. Selon le procédé, on découpe une ébauche de doublure à partir d'une feuille de matière thermoplastique présentant une dureté appropriée, et on porte l'ébauche à une température à laquelle elle se ramollit suffisamment pour permettre l'adaptation de sa forme. Ensuite, on place l'ébauche dans le casque, on place celui-ci sur la tête de l'utilisateur auquel il est destiné, et on exerce sur la tête une pression suffisante pour que l'ébauche s'adapte à la forme de la tête et à celle du casque. On ne relâche la pression qu'après refroidissement de l'ébauche jusqu'à une température à laquelle la matière conserve sa forme. Enfin, on fixe la doublure au casque à l'aide d'éléments de fixation appliqués sur le casque et/ou la doublure. On a également prévu un casque équipé d'une doublure adaptée selon ce procédé.
