  • Patent number: 4901374
    Abstract: Disclosed is a shield for protecting the eyes and at least the upper half or more of the face of the wearer and comprises a head-encircling element having a frontal part of relatively rigid material provided with oppositely extending wings for receiving pockets on a headband. The frontal part is configured to conform to the brow of the wearer and a compatibly configured frame is mounted on the frontal part by a transverse hinge. A protective screen of transparent nature depends from the frame in a protective mode and, because of the hinge, can be swung forwardly and upwardly away from and downwardly and rearwardly back to the protective mode. The screen may be removed from the frame and the headband from the frontal part for laundering, sterilizing, etc.
