Most helmets have tool-free adjustments, but on older models, the helmet size is adjusted by loosening the screws on the side to slide the front portion forward or back.
The shell of a hockey helmet is generally made of a substance called vinyl nitrile that disperses force from the point of contact, while the liner may be made of either vinyl nitrile foam, expanded polypropylene foam, or other material to absorb the energy, to reduce the chances of concussion.
Helmets in the National Hockey League
The first player to regularly wear a helmet for protective purposes was George Owen, who played for the Boston Bruins in 1928–29. In 1927, Barney Stanley presented a prototype of a helmet at the NHL's annual meeting. It was quickly rejected.
Helmets appeared after the Ace Bailey–Eddie Shore incident on December 12, 1933, as a result of which Bailey almost died and Shore suffered a severe head injury. After that, Art Ross engineered a new helmet design and when the Boston Bruins took to the ice in a game against the Ottawa Senators, most of the players donned the new helmet. Most Bruins players didn't wear the helmet after the game, with the exception of Eddie Shore, who wore it the rest of his career. In the 1930s, the Toronto Maple Leafs players were ordered to add helmets to their equipment. A few minutes into the first game with the new helmets, the popular King Clancy famously flung his off. The helmets were generally unpopular with fans, media, and other players. A few players, such as Des Smith, Bill Mosienko, Dit Clapper, and Don Gallinger continued to don helmets.
During the Original Six era, Maurice Richard and Elmer Lach briefly wore helmets. Jack Crawford wore a helmet to hide his bald head and Charlie Burns wearing one to protect the metal plates in his head from an injury incurred in playing junior ice hockey, predating his NHL career.
The death of Bill Masterton from a brain injury in a January 13, 1968 in a game between the Minnesota North Stars and Oakland Seals started to change perceptions surrounding helmets. Helmet use began to gradually increase during the 1970s, with Ted Green being the first Bruins player since Shore to wear one as a result of his NHL career, for the 1970-71 NHL season and onwards for the same reason that Charlie Burns had worn a helmet, until Green's retirement from pro hockey in 1979. The 1972 Summit Series showcased an entirely helmet clad Soviet Union team, with Paul Henderson being the only Canadian to sport a helmet. Usage increased to the point that 70% of NHL players were wearing them by 1979.
In August 1979, then President of the National Hockey League (NHL), John Ziegler, announced that protective helmets would become mandatory for incoming players in the NHL. "The introduction of the helmet rule will be an additional safety factor," he said. The rule allowed players who signed professional contracts prior to June 1, 1979 to continue to not wear a helmet provided a liability waiver was signed, if they so desired. The last player to play without a helmet was Craig MacTavish, who played his final game during the 1996–97 season for the St. Louis Blues.
Visors and shields
A visor or shield in ice hockey is a device attached to the front of a helmet to reduce potential of injury to the face. Visors cover the upper half of the face, while full face shields cover the entire face. A series of eye injuries, most notably that to Bruce Fogarty, have led to a call from many to enforce their wearing. As of 2013[update], 73% of NHL players wear visors. Many other leagues around the world mandate the use of visors. Visors and shields, made of a high impact-resistant plastic, offer better overall vision than the wire cages available, which can obscure vision in certain areas. The face shield provides excellent straight ahead and peripheral vision, but does not provide as good air flow as a cage.
The American Hockey League, the top minor league in North America required all players to wear shields prior to the start of the 2006–07 season. The NHL "strongly recommends" the use of visors. The National Hockey League mandated visors in 2013, with an exception for players having 25 games experience.
Full facial protection
A cage in ice hockey is a device attached to the front of a helmet to reduce potential of injury to the face. It consists of a metal or composite mesh that covers the entire face, although some half cages do exist (to protect the eyes while allowing full airflow). The bars, or cage, are spaced far enough apart to allow seeing through to the action but are close enough to stop pucks and sticks from getting through to injure the face.
Some manufacturers now offer the best of both designs—a plastic face shield to protect the eyes and upper part of the face, and a cage to cover the lower jaw and to add ventilation. Full facial protection is mandatory in many amateur leagues and in North America, full face cages, full shields, or shield & cage combination are mandatory in high school hockey, college hockey, and for all players under the age of 18.
Facial protection research
In 2002, the British Journal of Sports Medicine published a study identifying the protection offered against concussions between the half-face shield and the full face shield. The use of a full face shield compared with half face shield significantly reduced the playing time lost because of concussion, suggesting that concussion severity may be reduced by the use of a full face shield.
