Abstract
Safety spectacles have an inner frame of hard elastic plastic material extending from one end piece, across the bridge to the other end piece. The base plates for the side piece hinges are embedded in the inner frame. A continuous wire is embedded in the inner frame. The inner frame is completely covered with a soft, elastic, polyurethane foam several millimeters thick which determines the shape of the spectacles.
