Head and neck restraint systems refer to extensions of the helmets used for purposes of protection. They are a compulsory requirement in all racing sports and drivers are hindered from participating in races if they do not wear them. They are used as a safety mechanism against potential injuries that can be obtained from car accidents. They function by reducing the degree of strain on necks due to impact.
These systems have been developed following the high number of people who die from head and neck injuries. Statistics show that over fifty percent of deaths result due to basilar skull fracture. This percentage is highly reduced when drivers use these devices. Such fractures are only caused by very large amounts of impacts, more than four thousand Newtons.
The body is usually restrained by harnesses, which pin them firmly onto seats. The head is protected by helmets but still remain floating and only restrained by the neck. This makes it necessary to restrain the skull further so as to reduce the impact on it in case of a collision. They also absorb the excess energy that results from such impact. In so doing, the energy transmitted to the necks is highly reduced. The force that finally reaches the necks is small enough to cause no significant injury.
Head and neck restraints are built using a variety of materials. The primary one is carbon-fiber, although others like, sponge, cotton, metal plates, and plastics are also integrated. The material should be tough enough as the level of stress it is supposed to bear is also large. It also must not break with ease as that would leave the equipment unsafe because broken bits can in themselves injure a person.
The device is U-shaped with tethers, helmet anchors, shoulder supports, and two slightly longer arms which lie on the chest when worn. The arms rest on the pectoral muscles. The back is set behind the nape of the necks. The shoulders are the main support for the devices.
Straps do all attachments from the equipment to all other external parts. The major support to the heads is done on the helmet by use of straps. These straps have plastic or metallic buckles, which are locked to maintain the helmet in position. Other straps go under the armpit, around the back, and around the chest. They are positioned the same way as Hutchens device but they are a little behind.
They come in a broad variety of colors. Normally their color matches with that of the helmets. They can also be produced with various patterns, spots, plain colors, or strips. The interior surface is lined with cushions for absorbing shock that come from impacts. The external surface is made tough to stop piercing through by pointed objects.
Head and neck restraint systems are very useful in the racing industry. Since their invention, they have undergone a lot of modifications, which have made them very effective at their work. The production cost has gone down making them cheaper. Many companies have also entered into the industry to manufacture better products.
