Designed for protection of the head in combat, or in civilian life, from sports injuries, falling objects or high-speed collisions.
Helmets are common in the military, construction, mining, and some sports, including American football, baseball, ski, snowboarding, ice hockey, equestrian sports, motorsports, and rock climbing. Motorcycle helmets and bicycle helmets are compulsory headgear in some jurisdictions; in the United Kingdom only Sikhs are allowed to ride motorcycles without wearing motorcycle helmets. Bicycle helmet compulsion and even strong promotion has been a heated subject of debate amongst cyclists and scientists since at least the 1990s, lately focusing on alleged net protective effect at the population level.
Military origins and symbolism
-
Helmets were among the oldest forms of combat protection, and are known to have been worn by ancient Greeks, Romans, throughout the Middle Ages, and up to the end of the 1600s by many combatants. At that time, they were purely military equipment, protecting the head from cutting blows with swords, flying arrows, and low-velocity musketry. Some helmets, in order to protect the neck as well, have a sort of extension made of leather strips called pteruges, particularilly common in the middle east. They were initially constructed from leather, and then bronze and iron during the Bronze and Iron Ages, but soon came to be made entirely from forged steel in many societies after about 950A.D. Military use of helmets declined after 1670, and rifled firearms ended their use by foot soldiers after 1700. By the 18th century, cavalry units often wore steel body cuirasses, and frequently metal skull protectors under their hats, called \"secrets\". The Prussian spiked helmet, or Pickelhaube, offered almost no protection from the increased use of heavy artillery during World War I, and in 1916 was replaced by the German steel helmet, or Stahlhelm, and afterwards it was worn merely for tradition.
The Napoleonic era saw ornate cavalry helmets reintroduced for cuirassiers and dragoons in some armies; they continued to be used by French forces during World War I as late as 1915, when they were replaced by the new French Adrian helmet. It was soon followed by the adoption of similar steel helmets by the other warring nations.
World War I and its increased use of heavy artillery had renewed the need for steel helmets, which were quickly introduced by all the combatant nations for their foot soldiers. In the 20th century, such helmets offered protection for the head from shrapnel and spent, or glancing, bullets.
