How a lightweight safety helmet functions

Shock-absorbing helmets (in difference to bulletproof helmets) are designed to absorb as much as possible of the impact force to the head in the event of an impact, thus mitigating the impact. The aim is to protect the head as good as possible from concussion or even fatal impact. By absorbing the impact energy, the EPS helmet body is compressed or even breaks. Roughly converted, a lightweight helmet must be able to "absorb" at least 3/4 of the impact force specified by standard. This means that under laboratory conditions, a maximum of 1/4 of the output impact force may finally reach the head. Depending on the area of application and the standard, other important factors are  also tested, of course, such as in the penetration test: in piste accidents, ski poles, for example, pose a potential danger to the skier, so it is tested whether the ski helmet can withstand this sort of penetration.

Picture reference: Thanks for the pictures sent to us by a passionate mountain biker from Hungary, who survived a frontal collision in uneven terrain at speed 40km/h without head injuries! We wish you a good recovery and are glad that this bike helmet did a great job here!
