PURPOSE: A safety helmet is provided, which enables more sanitary use by preventing sweat and dust from infiltrating into the helmet. CONSTITUTION: A safety helmet comprises an outer cover(2) of hard material, lining(4), and buffer material. The outer cover protects the head from shock in collisions with a dropping object or a structure. The lining covers the circumference of the head while being combined with the inside of the outer cover. The buffer material is formed between the outer cover and provides insulation, soundproofing, and shock absorption. The lining is comprised of an overhead strap(4a) and a head holding strap(4b). |
