A motorcycle helmet is a headgear for the practice of Motorcycle. It aims to protect the driver’s head by absorbing the impact with the ground or natural obstacles during a fall, but also to protect the abrasion caused by slipping on the floor.
The helmet also has an eye protection against wind, insects, or even a function of pure comfort including an air conditioning or heating and Speakers for listening to music or a travelling companion.
A 2004 study in New Zealand indicates that wearing a helmet and motorcycle jackets reduces the risk of accidents by 24%.
The motorcycle helmets protect the head by the absorption of some more or less of the kinetic energy impact. The greater the amount of energy absorbed by the deformation or destruction of the helmet is important, better head will be protected. The energy absorption is provided by its destruction. Therefore any helmet, as like leather pants, must be changed after an accident because its protective capacity is diminished.
The outer shell protects against the risk of penetration of the helmet by sharp objects. At the same time it ensures the sliding of the helmet on surfaces impacted a tangentially. The fairing internal compounds expanded materials absorbs impact energy by crushing. The padding foam lightweight and fabric provides a comfortable contact, protection against cold, against the engine noise and drafts.
