The function of safety helmets

Protective equipment to prevent head injury from impact objects. Composed of a hat shell, hat lining, lower cheek strap, and rear hoop. The cap shell is semi-spherical, sturdy, smooth, and has a certain degree of elasticity. The impact and puncture kinetic energy of the striking object are mainly borne by the cap shell. There is a certain space left between the cap shell and the cap lining to cushion and disperse instantaneous impact force, thereby avoiding or reducing direct injury to the head. Impact absorption performance, puncture resistance, lateral rigidity, electrical insulation, and flame retardancy are the basic technical requirements for safety helmets.
