Abstract
An eye protection transparent shield for use with a headgear. The shield comprises a visor of transparent material and having opposed side connecting portions for pivotal securement to the headgear. The visor has an eye viewing portion and a nose support piece. A pivotal locking mechanism attaches each of the opposed side connecting portions to the headgear. The pivotal locking mechanism has a pivot connection and a guide mechanism for displacing the visor from a position of use, in front of the wearer's eyes, to a position of non-use above the wearer's eyes. The visor is arrested at both positions by a resiliently biased element which also applies a continuous retention force.
