Abstract

An interior material for a helmet according to an embodiment of the present disclosure includes an interior material body and a plurality of buffer parts protruding from the interior material body.

What is claimed is: 
     
         1 . An interior material for a helmet, comprising:
 an interior material body; and   a plurality of buffer parts protruding from the interior material body.   
     
     
         2 . The interior material of  claim 1 , wherein the buffer part includes:
 a central buffer member located at a center of the interior material body; and   an outer buffer member disposed to surround the central buffer member and spaced a certain distance from the central buffer part.   
     
     
         3 . The interior material of  claim 2 , wherein an opening hole is formed in the outer buffer member. 
     
     
         4 . The interior material of  claim 2 , wherein an opening hole is formed in an area between the central buffer member and the outer buffer member. 
     
     
         5 . The interior material of  claim 2 , wherein a protrusion is provided on at least one of the central buffer member and the outer buffer member. 
     
     
         6 . The interior material of  claim 2 , wherein the central buffer member is provided with a protrusion, and
 the outer buffer member includes a first outer buffer member provided with a protrusion and a second outer buffer member not provided with the protrusion.   
     
     
         7 . The interior material of  claim 6 , wherein the first outer buffer member is provided as a plurality of first outer buffer members, and the second outer buffer member is disposed between the first outer buffer members. 
     
     
         8 . The interior material of  claim 5 , wherein the protrusion includes a first part having a first height and a second part having a second height that is higher than the first height. 
     
     
         9 . The interior material of  claim 8 , wherein the protrusion is provided on the outer buffer member, and
 a distance between the first part and the central buffer member is smaller than a distance between the second part and the central buffer member.   
     
     
         10 . The interior material of  claim 5 , wherein the protrusion includes a first part having a first surface area and a second part having a second surface area that is larger than the first surface area. 
     
     
         11 . The interior material of  claim 10 , wherein the protrusion is provided on the outer buffer member, and
 a distance between the first part and the central buffer member is smaller than a distance between the second part and the central buffer member.   
     
     
         12 . The interior material of  claim 5 , wherein a recessed portion is formed in the protrusion. 
     
     
         13 . The interior material of  claim 12 , wherein an inclined surface is formed on the recessed portion. 
     
     
         14 . The interior material of  claim 12 , wherein the protrusion is provided on the central buffer member. 
     
     
         15 . A helmet comprising the interior material for a helmet of  claim 1 .
