Headrest pole guide

Abstract

A headrest pole guide structure may include a main body configured to be fixed to a seat back and disposed inside a seat cover, the main body having an upper surface in contact with a lower surface of the seat cover and a hollow space so that a pole may be selectively inserted into the hollow space, and a head disposed above the main body, wherein the head may be fastened to the main body with the seat cover interposed between the main body and the head.

What is claimed is: 
     
         1 . A headrest pole guide structure, comprising:
 a main body configured to be fixed to a seat back and disposed inside a seat cover, the main body having an upper surface in contact with a lower surface of the seat cover and a hollow space so that a pole is selectively inserted into the hollow space; and   a head disposed above the main body,   wherein the head is fastened to the main body with the seat cover interposed between the main body and the head.   
     
     
         2 . The headrest pole guide structure as set forth in  claim 1 , wherein the head is provided with a height adjustment lever to adjust a relative position of the pole with respect to the main body. 
     
     
         3 . The headrest pole guide structure as set forth in  claim 1 , further including a connector provided between the main body and the head and being connected at an upper end thereof to the head and coupled at a lower end thereof to the main body through the seat cover. 
     
     
         4 . The headrest pole guide structure as set forth in  claim 3 ,
 wherein the connector includes, in a lower portion thereof, a plurality of coupling hooks protruding downward through the seat cover, and   wherein the main body has a plurality of hook depressions and the coupling hooks are locked to the corresponding hook depressions under the seat cover.   
     
     
         5 . The headrest pole guide structure as set forth in  claim 4 , wherein the plurality of coupling hooks are bent outward on lower ends thereof based on a center therebetween. 
     
     
         6 . The headrest pole guide structure as set forth in  claim 3 , wherein a lower portion of the connector is coupled to the hollow space of the main body. 
     
     
         7 . The headrest pole guide structure as set forth in  claim 1 , wherein the head has:
 an insert hole communicating with the hollow space of the main body in a central portion thereof so that the pole is configured to be inserted into the hollow space through the insert hole; and   a perimeter portion defining the insert hole, the perimeter portion facing the upper surface of the main body and being configured such that the perimeter portion of the head and the upper surface of the main body compress the seat cover upward and downward when the main body and the head are coupled each other, and   wherein the main body includes:
 a flange part having the upper surface and compressing the seat cover interposed between the flange part and the perimeter portion of the head when the main body and the head are coupled each other; and 
 a guide part integrally extending downward from the flange part, the guide guiding linear sliding movement of the pole. 
   
     
     
         8 . The headrest pole guide structure as set forth in  claim 7 , wherein the flange part of the main body forms is configured such that the upper surface thereof is inclined with respect to the guide part.
