Helmets

Helmet is a strong protective hat or caps that various types of users such as soldiers, police officers, firefighters, motorcyclists, athletes, and others vehicle riders usually wears during their driving period or duty hours. Helmets are the safety gear of two wheeler vehicles. All helmets effort to protect the user's head by absorbing unconscious energy and protecting against penetration. Their structure and protective capacity are altered in high-energy impacts. Beside their energy consuming capability, their volume and weight are also important issues, since higher volume and weight increase the injury risk for the user's head and neck.
