Zusammenfassung:PROBLEM TO BE SOLVED: To obtain a naturally degradable helmet not requiring a recycling treatment and an incineration treatment on the scrapping of the helmet and capable of being naturally degraded, also when buried or left, by making up the main parts of the helmet from biodegradable materials. SOLUTION: This helmet is obtained by making up a cap boy 1, an impact- absorbing liner 2, a head band 5, and a hunger 6 from a biodegradable plastic as a biodegradable material, and further making up a ceiling pad 3, a hammock 4, a chin strap 7 and a sweat stopper 8 from woven or knitted fabrics produced from fibrous materials comprising a biodegradable polymer.
