Integral complex buffing structure of safety helmet

Integral complex buffing structure of safety helmet, comprising a casing, a lining body and a buffing body integrally disposed between the casing and the lining body, the casing being made of a hard plastic material, the lining body being connected on inner face of the casing and made of hardened foam material with high density, the buffing body being made of low-resistance material with low density, whereby when suffering greater inertial impacting force from outer side of the casing, the buffing body is able to fully distribute the impact to a larger area so as to reduce the impact energy exerted onto unit area of the lining body and spread the inward concentrated impact, after the impact energy is fully spread, the instantaneous deformation of the casing and the lining body caused by the impact being reduced, whereby the respective layers of the helmet can naturally automatically restore to their original state and position and thus the helmet is excellently anti-impact with respect to many times of or continuous impact at one point.
