Helmet manufacturer The role of the helmet: when a collision occurs, the head can slide in the helmet, so as to slow down the injury, protect yourself, and reduce the injury caused by dangerous situations to a relatively low level.

While most helmets are developed, the tested helmets are used to impact objects in the front, and the built-in sensor data is read as the safety and research and development standard. This test is very useful for preventing bone cracks and fractures in the head.

But you can recall the actual situation when the accident happened. More commonly, it contacts the ground or objects at an angle. This is the moment when it comes into play. When you hit an object at a certain speed, the current contact will directly generate a rotating force on your brain.

These oblique impacts will cause the soft tissue of the brain to be cut, which will cause damage. In the existing helmet technology, when the helmet contacts with an object, the head and neck will be completely fixed, and slip will occur within a few seconds to protect the head.
