Football helmet

The **football helmet** is a piece of protective equipment used mainly in gridiron football. It consists of a hard plastic shell with thick padding on the inside, a face mask made of one or more plastic-coated metal bars, and a chinstrap. Each position has a different type of face mask to balance protection and visibility, and some players add polycarbonate visors to their helmets, which are used to protect their eyes from glare and impacts. Helmets are a requirement at all levels of organized football, except for non-tackle variations such as flag football. Although they are protective, players can and do still suffer head injuries such as concussions.

Football helmets have changed dramatically with the modernization of the sport to facilitate technological changes and to improve the safety of the game. Despite lower rates of some injuries, serious traumas to the head are still common, and determining the consequences of these traumas is an active area of research. In addition to the acute concern about traumatic brain injuries, such as concussions, studies have found players increase their risk for long-term problems such as chronic traumatic encephalopathy (CTE). Football helmets present a unique design challenge because, unlike bicycle helmets, which are thrown out after a single hit, football helmets need to withstand multiple impacts.

## History

### Invention

One of the first instances of football headgear dates to 1896 when Lafayette College halfback George "Rose" Barclay began to use straps and earpieces to protect his ears. It is not certain who invented the football helmet. Many sources give credit for the creation of the helmet to James Naismith, while other sources credit U.S. Naval Academy Midshipman Joseph M. Reeves (later to become the "Father of Carrier Aviation"), who had a protective device for his head made out of mole skin to allow him to play in the 1893 Army–Navy game. Reeves had been advised by a Navy doctor that another kick to his head would result in "instant insanity" or even death, so he commissioned an Annapolis shoemaker to make him a helmet out of leather. Later, helmets were made of padded leather and resembled aviators' helmets or modern day scrum caps. At least in professional football, they were optional. Some National Football League players, notably Hall-of-Famer Bill Hewitt, played all or most of their careers without a helmet.

### Early years

One innovation from the early 1900s period was hardened leather. 1917 marked the first time helmets were raised above the head in an attempt to direct blows away from the top of the head. Ear flaps also had their downfall during this period as they had little ventilation and made it difficult for players to hear. The 1920s marked the first time that helmets were widely used in the sport of football. These helmets were made of leather and had some padding on the inside, but the padding was insufficient and provided little protection. In addition, they lacked face masks. As a result, injuries were very common. Early helmets also absorbed a lot of heat, making them very uncomfortable to wear.

In 1939, the Riddell Company of Chicago, Illinois started manufacturing plastic helmets because it felt that plastic helmets would be safer than those made of leather. Plastic was found to be more effective because it held its shape when full collision contact occurred on a play. These helmets were also much more comfortable and had more padding to cushion the head in an impact. Included with the plastic helmet came plastic face mask, which allowed the helmet to protect the entire head. By the mid-1940s, helmets were required in the NFL. They were still made of leather, but with improved manufacturing techniques had assumed their more familiar spherical shape. The NFL initially allowed either plastic or leather helmets, but in 1948 the league outlawed the plastic helmet, considering the hard-plastic material to be an injury risk. The NFL lifted the plastic helmet ban after just one year in 1949, and by 1950, the plastic helmet had become universal in that league.

### Introduction of advanced materials

By the 1950s, the introduction of polymers ended the leather helmet era. The last leather helmet manufacturer, MacGregor, ceased production of leather helmets in the mid-1960s. The NFL also recommended face masks for players in 1955, reducing the number of broken noses and teeth, but also necessitating new rules prohibiting opposing players from grabbing the face mask. By varying accounts, either Pat Studstill or Garo Yepremian was the last to forgo the facemask; among non-kickers, Tommy McDonald was the last to do so.

### Recent designs

In 2002, American football equipment manufacturer Riddell released a new design of helmet called the Revolution in response to a study concussions. In addition, Riddell has recently come out with a new design of helmets, the Riddell Speed Flex. This helmet came out in 2014. This new helmet uses elements of Riddell's older helmets, the 360 and the Revolution, such as Side Impact Protection and All Points Quick Release face mask attachment system.

Demand for a safer helmet prompted Schutt Sports to announce the arrival of a next generation helmet, the ION 4D, which included an integrated face guard. This new face guard design features shock absorbing "Energy Wedges" that reduce the force of impacts to the face guard. College teams wearing the helmet include Air Force, Penn State and Virginia. Schutt has also distinguished between their varsity helmets and youth helmets. The varsity helmets from Schutt are made with polycarbonate, which is a very strong polymer designed to take bigger hits. The Schutt youth helmets however; are made from ABS, which is a lighter material, meant for kids who do not take as powerful of hits.

Recently, a brand new type of helmet has come into play. Vicis is a new company that is producing helmets that have a softer outer layer. The softer layer absorbs more energy from impacts. In addition, the inside of the helmet also has a foam like substance which absorbs energy and improves comfort.
