Safety helmet capable of absorbing multi-direction impact

Abstract

A helmet includes a shell, a flexible frame having an inner surface and an outer surface attached to the inner surface of the shell, a pad having an inner surface and an outer surface attached to the inner surface of the shell and the inner surface of the flexible frame, and a slide-facilitating member attached to the inner surface of the pad. In virtue of the slide-facilitating member, the shell and the flexible frame can slide with respect to a user's head wearing it when receiving incoming impact, so that the helmet can absorb and convert energy of the incoming impact force into other forms of energy, thereby enhancing protection to the user's head.

What is claimed is: 
     
         1 . A helmet comprising:
 a shell having an inner surface;   a flexible frame attached to the inner surface of the shell and having an inner surface;   a pad having an inner surface and an outer surface attached to the inner surface of the shell and the inner surface of the flexible frame; and   a slide-facilitating member attached to the inner surface of the pad and serving to allow the shell and the flexible frame to slide with respect to a user's head wearing it when the shell receives incoming impact.   
     
     
         2 . The helmet as claimed in  claim 1 , wherein the slide-facilitating member protrudes out of the inner surface of the pad. 
     
     
         3 . The helmet as claimed in  claim 1 , wherein the slide-facilitating member is positioned in a recess provided at the inner surface of the pad. 
     
     
         4 . The helmet as claimed in  claim 1 , wherein the slide-facilitating member is covered by the pad. 
     
     
         5 . The helmet as claimed in  claim 1 , wherein the slide-facilitating member has a covering attached to the inner surface of the flexible frame, and a slide-facilitating medium wrapped by the covering. 
     
     
         6 . The helmet as claimed in  claim 5 , wherein the slide-facilitating medium is a colloid. 
     
     
         7 . The helmet as claimed in  claim 1 , wherein the slide-facilitating member has a substrate attached to the inner surface of the flexible frame and a plurality of flexible bars connected to the substrate.
