Integral complex buffing structure of safety helmet

Abstract

Integral complex buffing structure of safety helmet, including a casing, a lining body and a buffing body integrally sandwiched between the casing and the lining body. The casing is made of a hard plastic material. The lining body is connected on inner face of the casing and made of hardened foam material with high density. The buffing body is made of soft shock-absorbent material with low density. The buffing body is able to fully distribute the external concentrated impact to larger area of respective layers so as to reduce the linearly transmitted inertial impact. After the impact energy is fully spread, the instantaneous deformation of the casing and the lining body is 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.

What is claimed is:  
     
         1 . 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.  
     
     
         2 . Integral complex buffing structure of safety helmet as claimed in  claim 1 , wherein the buffing body is formed with beehive structures facing the lining body.  
     
     
         3 . Integral complex buffing structure of safety helmet as claimed in  claim 2 , wherein the beehive structures are dents.  
     
     
         4 . Integral complex buffing structure of safety helmet as claimed in  claim 2 , wherein the beehive structures are perforations passing through the buffing body.  
     
     
         5 . Integral complex buffing structure of safety helmet as claimed in  claim 2 , wherein the lining body is integrally foamed with a configuration corresponding to the dents or perforations of the beehive structures so as to fill the dents or perforations and achieve a good connection between the lining body and the buffing body.  
     
     
         6 . Integral complex buffing structure of safety helmet as claimed in  claim 3 , wherein the lining body is integrally foamed with a configuration corresponding to the dents or perforations of the beehive structures so as to fill the dents or perforations and achieve a good connection between the lining body and the buffing body.  
     
     
         7 . Integral complex buffing structure of safety helmet as claimed in  claim 4 , wherein the lining body is integrally foamed with a configuration corresponding to the dents or perforations of the beehive structures so as to fill the dents or perforations and achieve a good connection between the lining body and the buffing body.  
     
     
         8 . Integral complex buffing structure of safety helmet as claimed in  claim 1 , wherein a mesh body is parallelly disposed between the lining body and the buffing body or disposed in at least one of the lining body and the buffing body.  
     
     
         9 . Integral complex buffing structure of safety helmet as claimed in  claim 2 , wherein a mesh body is parallelly disposed between the lining body and the buffing body or disposed in at least one of the lining body and the buffing body.  
     
     
         10 . Integral complex buffing structure of safety helmet as claimed in  claim 3 , wherein a mesh body is parallelly disposed between the lining body and the buffing body or disposed in at least one of the lining body and the buffing body.  
     
     
         11 . Integral complex buffing structure of safety helmet as claimed in  claim 4 , wherein a mesh body is parallelly disposed between the lining body and the buffing body or disposed in at least one of the lining body and the buffing body.  
     
     
         12 . Integral complex buffing structure of safety helmet as claimed in  claim 5 , wherein a mesh body is parallelly disposed between the lining body and the buffing body or disposed in at least one of the lining body and the buffing body.  
     
     
         13 . Integral complex buffing structure of safety helmet as claimed in  claim 6 , wherein a mesh body is parallelly disposed between the lining body and the buffing body or disposed in at least one of the lining body and the buffing body.  
     
     
         14 . Integral complex buffing structure of safety helmet as claimed in  claim 7 , wherein a mesh body is parallelly disposed between the lining body and the buffing body or disposed in at least one of the lining body and the buffing body.
