Abstract
Abstract A protective head-wear including a shell or helmet-like member for protecting the head of a wearer and a face shield of the full face protective type. The face shield may be constructed of a transparent member such as a solid clear plastic or alternatively of wire mesh. In either event, about the peripheral edge of the face shield there is provided a rim which may be constructed of a separate wire or may be formal integrally with the shield. Shock absorbing resiliently deformable means is disposed between the face shield and the shell to absorb forces applied to the face shield as a result of impact thereon. The resiliently deformable member may be a rubber-like strip secured to the periphery of the forward edge of the helmet and engagable by the rim on the face shield. Alternatively, the shock absorbing member may be resiliently deformable member incorporated into a means for attaching the face shield to the shell.
