Abstract

PURPOSE: To obtain a safety helmet cover for protecting and preventing fouling by a method wherein an air removing hole is bored to a top section of a cover layer of the safety helmet, a plurality of slits are formed to a bending clearance plate connected to an outer fringe of the cover layer and a perforation, etc. are formed along the outer fringe.
CONSTITUTION: The air removing hole 2 is bored at a central section of an elastic sheet 1 in thermoplastic synthetic resin, such as polyethylene, polyvinyl chloride, etc., the sheet is heated and pressure-bonded in a safety helmet-shaped form and the cover layer 3 of the safety helmet is made up. In this case, the remainder sheet, which is connected to the outer fringe 4 of the layer 3 and extends in the horizontal direction, is cut in parallel with the outer fringe 4 to form the bending clearance plate 5, and the perforation 12 or a slit line 13 is made up along an edge 4 of the outer fringe 4. The perforation 14 or a slit line 15 for exfoliation is formed along the perforation 12 or the slit line 13, the cover layer 3 is fitted on an upper surface of the safety helmet 10, and the bending clearance plate 5 is folded back to an inner surface of the safety helmet 10, and glued on the inner surface with an adhesive tape 16, etc.
