The eye protection lens of safety goggles provides increased impact protection without utilizing external fasteners or external sealing means. The mechanical attachment of the lens to the goggles rim is improved and stabilized against separation forces by the interlocking engagement of a wedge shaped retainer rib formed along the periphery of the safety lens. The lens support frame has a retainer rim which is intersected by an open slot, thereby defining an outside body portion and an inside body portion. An annular shoulder is formed on the inside body portion and partially closes the open slot. The retainer rib is received within the slot, with its apex being engaged against the inside body portion of the goggles rim, and the wedge portion of the retainer rib being disposed in overlapping, interlocking engagement with the annular shoulder.
Verre pour lunettes de sécurité offrant une protection accrue contre l'impact sans recours à des éléments de fixation ou de scellement externes. La fixation mécanique du verre au cercle de la monture des lunettes se trouve améliorée et protégée contre les forces de séparation par imbrication d'un rebord de retenue en forme de coin formé à la périphérie du verre de sécurité. La monture du verre de sécurité comporte un cercle de retenue comportant une encoche ouverte qui définit une partie externe et une partie interne. Un épaulement annulaire formé sur la partie interne ferme partiellement l'encoche. Le rebord de retenue vient se loger dans l'encoche, avec le sommet du rebord de retenue orienté vers le côté intérieur de la monture, en imbrication complète avec l'épaulement annulaire.
