CA 2561540

A helmet having a helmet shell including cooperating first and second sections in slidable engagement with one another, at least one locking assembly interconnecting the first and second sections, the locking assembly including a pivoting member pivotable between a locked position and an unlocked position, the pivoting member in the locked position pressing the shell sections against one another such as to prevent a relative sliding motion therebetween, the pivoting member in the unlocked position allowing the relative sliding motion, and at least one engagement member connected to the first shell section and removably engaging the pivoting member in the locked position to prevent accidental movement of the pivoting member toward the unlocked position.

Le casque consiste en une coque comprenant deux sections solidaires qui coulissent l'une dans l'autre. Au moins un système de verrouillage doit bloquer en position la première et la seconde section. Ce système doit comporter un élément articulé capable d'alterner entre la position verrouillée et la position déverrouillée. En position verrouillée, l'élément articulé doit maintenir les sections de coque pressées l'une contre l'autre de manière à empêcher tout glissement d'une section par rapport à l'autre. En position déverrouillée, l'élément articulé doit autoriser le glissement des sections l'une par rapport à l'autre. Au moins un élément d'accrochage relié à la première section de coque et amovible doit bloquer l'élément articulé dans la position verrouillée afin d'empêcher tout déplacement accidentel de cet élément vers la position déverrouillée.
