1. Shell: The shell of the helmet plays an important role in the safety of the helmet, so the choice of its material is very important. Generally, the materials used are ABS and glass fiber. A good helmet is made of carbon fiber, but it is expensive.
2. Buffer layer: The main function of the buffer layer is to absorb external impact. Imagine that if a helmet with a hard shell does not have a buffer layer, when it encounters an external force impact, the external force will directly act on the head through the hard shell, causing the head to be injured. Therefore, the thickness of the cushion layer and the quality of the material determine the cushioning capacity of the helmet. The buffer layer is mainly made of expanded styrene material.
3. Inner lining: the main function is to enhance the comfort when wearing, generally made of soft flannel.
4. Strap: The function of the strap is to firmly fix the helmet on the head, and its combination methods are: camphor type, ring buckle type, and cloth type.
5. Jaw guard: The jaw guard is a part of a full-face helmet, that is, there are more parts to protect the lips and jaw below the nose, and give more protection to the face when it is impacted. Full-face helmets generally have air inlets and air outlets.
6. Visor: Visor can protect the eyes and face, and are made of plastic (such as polycarbonate resin) and strengthened glass (such as PMMA resin), among which the scratch-resistant performance of strengthened glass Very good. It is recommended that readers choose better materials as much as possible for the visor, because poorer materials are easily broken and stab the face when impacted.
