摘要
A protective screen to protect the face and, above all, the eyes of a person against flying particles and sharp objects has a mesh with a mesh structure which is formed from a plurality of adjacent rows of hexagonal openings, which rows are bounded by mesh webs common to the openings. The openings in the mesh are each osubstantially the same area. The mesh is enclosed by an edge with no mesh structure which has a width which is at least equal to the height of a row of openings in the mesh structure. The mesh webs of at least two rows of openings adjacent to the edge can be made thicker than the mesh webs for the other openings, wherein, however, all the openings in the mesh are nevertheless substantially identical in area. The mesh is produced by etching spring steel sheet. A visor for a safety helmet, especially a forestry worker's helmet is produced from the protective screen by injection moulding a supporting frame around its edge.
