Abstract

Cette invention concerne un dispositif de protection muni d'une visière en matière plastique. Cette visière est fixée de façon amovible mais résistante sur un support monté sur le dispositif. La visière présente une fente allongée dans laquelle est logée une came. Le lobe de cette came est légèrement plus long de la dimension transversale de la fente, de sorte que lors de la rotation de la came entre la position de dégagement et la position de blocage, il déforme légèrement la fente, celle-ci revenant sensiblement à sa dimension initiale lorsque le lobe de la came parvient dans la position de verrouillage. Cette came maintient ensuite la visière dans une condition tendue et la fente resserrée empêche la rotation de la came, de sorte que celle-ci demeure dans sa position de verrouillage. Une disposition de ce type est utilisable notamment pour la fixation des visières sur les casques de protection.This invention relates to a protective device provided with a plastic visor. This visor is fixed in a removable but resistant manner on a support mounted on the device. The visor has an elongated slot in which a cam is housed. The lobe of this cam is slightly longer than the transverse dimension of the slot, so that when the cam rotates between the disengaged position and the locked position, it slightly deforms the slot, the latter substantially returning to its initial dimension when the lobe of the cam reaches the locking position. This cam then maintains the visor in a taut condition and the tightened slot prevents rotation of the cam so that the cam remains in its locked position. An arrangement of this type can be used in particular for fixing visors to protective helmets.
