Bicycle helmets are a means of passive road safety
A cyclist's skull should be protected by wearing a bicycle helmet in the event of an accident or a fall, at least partially absorbing the forces acting on the head. Basically, bicycle helmets are divided into the categories of micro shell, hard shell and soft shell helmets. The widespread micro-shell helmets are characterized by a smooth and thin plastic coating and ventilation openings. The hard shell helmets have an additional cover made of hard plastic. Due to the higher weight and lower wearing comfort, they are mostly only used in cycling. The soft shell helmets consist only of hard foam and, according to many expert opinions, are not sufficiently suitable as protection.
How do bike helmets protect?
The energy that arises, for example, when the head hits the ground is partially absorbed by the foam in the helmet and can prevent the skull from breaking to a certain degree. Abrasions, lacerations and bruises in areas covered by the helmet are also reduced. According to studies, bicycle helmets can avoid up to 70 percent of fatal head injuries in bicycle accidents. (vb)
