A helmet is one of the safety clothing that every rider should have. This gadget will keep you alive and protect you from getting injured in case of an accident. It is helpful in protecting the head, ear, and face. Most of the modern helmets are made using plastics, and they are reinforced with carbon fiber or kelvar. Helmets have a foam or fabric interior for protection and comfort.
A helmet is designed to break during a crash thus saving the rider. In general, a helmet is well-designed to absorb shock or impact instead of breaking the rider’s skull. Helmets should be replaced after a major impact because they do not offer much protection after the first impact. Again it is good to replace a helmet after every four years even if it has not sustained any impact.
Types of helmets
These gadgets are a classified according to the protection they offer
This one covers the head, including the skull’s base. Besides, it has a protective section that covers the rider’s chin and a plastic shield that covers the eyes. It is also designed with a plastic shield for shielding the eyes. The disadvantage of the full face helmet is that it affects the rider’s level of hearing as well as increasing the level of heat.
This is a special helmet that is designed to provide the minimum amount of coverage as allowed by the US law. It is secured chin straps that offers a high level of protection just like the full face one.
This is another type of a helmet that covers the skulls back without protecting the chin. Some of these helmets are designed with a visor to block out blinding headlights or bright sunlight. In addition to that, it has rear protection even if it does not provide much protection for your face.
Types of protective mechanisms
All helmets have two types of protections which include
The outer shell
This shell is made from fiberglass, acrylonitrile butadiene styrene plastic or kelvar. It is generally thin.This shell plays an important role of protecting the rider’s skull from getting a puncture. Again this shell is well designed such that it cannot disintegrate after hitting a hard surface such as concrete or pavement.
A soft inner liner
This layer is made from expanded polypropylene foam or expanded polystyrene foam. This liner is supposed to crush and increase the time and distance over which your helmet stops during impact reducing its acceleration.
