Helmet

Amelia Earhart wearing a helmet just before her transatlantic crossing of 1928

A helmet is a form of protective gear worn to protect the head from injuries.

Ceremonial or symbolic helmets (e.g. UK policeman's helmet) without protective function are sometimes used. The oldest known use of helmets was by Assyrian soldiers in 900BC, who wore thick leather or bronze helmets to protect the head from blunt object and sword blows and arrow strikes in combat. Soldiers still wear helmets, now often made from lightweight plastic materials.
