A mechanism includes two units for securing a transparent eye protector to a helmet having a recess at either side. Each unit comprises a bracket formed at one end of a frame of the eye protector. The bracket includes, at a free end thereof, an inner raised, round surface, radial first ridges on the raised, round surface, an outer recessed, round surface, and a central hole through the round surfaces. Separate snapping members include two lower, resilient latched pieces inserted into each recess for releasably securing to the helmet, radial second ridges at an upper, outer surface, and a central hole through the upper, outer surface. Bolts are driven through the central holes for fastening the snapping members and the brackets together. Pivoting of the ridges of the bracket about the ridges of the snapping member is done by pulling the eye protector up or down about the helmet.

1. A mechanism including two units for securing a transparent eye protector to a helmet having a recess at either side, each unit comprising:a bracket integrally formed with one end of an arcuate frame of the eye protector, the bracket having first and second opposing faces, with each bracket including, at a free end thereof, an inner raised, round surface raised beyond the first face, a plurality of equally spaced apart radial ridges on the inner raised, round surface, an outer recessed, round surface recessed below the second face, and a central hole through the inner raised and outer recessed round surfaces;snapping means including two lower, resilient latched pieces insertable into the respective recess for releasably securing to the helmet, a plurality of equally spaced apart radial ridges at an upper, outer surface, and a central aperture through the upper, outer surface, with the upper, outer surface being recessed to rotatably receive the inner raised, round surface;a bolt:a washer: anda nut, with the bolt driven through the central hole and aperture for fastening the snapping means and the bracket together, with the washer and nut being rotatably received in the outer recessed, round surface,wherein a pivoting of the ridges of the bracket about the ridges of the snapping means is done by passing the ridges of the bracket over the ridges of the snapping means, thereby fixing the eye protector with respect to the helmet. 2. The mechanism of claim 1, wherein the bolt comprises a flat on a shank thereof, with the central hole including a flat corresponding to the flat on the shank of the bolt.
