ABSTRACT:
Protective apparatus for shielding the eyes against the entrance of foreign matter. The apparatus includes a one-piece molded plastic visor which is formed of resilient material and includes a brim having an inner surface for engaging the forehead. The visor further includes a bill extending outwardly with the visor having first and second spaced legs extending rearwardly from the brim for compressively holding the head therebetween. The legs and the brim form a spring system which permits resilient deflection of the legs. The protective apparatus further includes a transparent shield dependent from the brim for overlaying the eyes. The shield includes a first end positioned adjacent the first leg and a second end disposed adjacent the second leg with an upper surface extending intermediate the ends and positioned closely adjacent the bill. The apparatus additionally includes a connection for fixably holding the shield to the brim. This connection is located inwardly of the shield ends to permit relative movement between the shield ends and adjacent portions of the brim when the legs are deflected thereby permitting mounting of the apparatus on the head.
