Pole guide for a headrest of an automobile

Abstract

The present invention provides a pole guide for a headrest of an automobile, which does not deform in high temperatures in welding in its manufacturing process, so that both side ends of the pole guide do not gape or warp at a joint thereof. The pole guide is obtained by pressing and forming a flat panel ( 31 ) on progressive dies, and the flat panel ( 31 ) is vertically provided with a fixing groove ( 32 ) at a upper part of a top end thereof, and provided with coupling elements ( 33 ) at both opposing side ends thereof to be engaged with each other.

1 . A pole guide for a headrest of an automobile, which is obtained by pressing and forming a flat panel on progressive dies to allow both side ends of the flat panel to be connected to each other, wherein the flat panel is vertically provided with a fixing groove at a upper part of a top end thereof, to which a holder for adjusting height of the headrest is fitted, and the flat panel is provided with coupling elements at both opposing side ends thereof to be engaged with each other, so that the flat panel cannot be separated, nor gape or warp at a joint of the opposing side ends.  
   
   
       2 . The pole guide as claimed in  claim 1 , wherein the coupling elements comprise prominences and depressions, which are respectively provided at both opposing side ends of the flat panel.  
   
   
       3 . The pole guide as claimed in  claim 2 , wherein auxiliary depressions are provided on both sides of a neck portion of the prominence of the coupling elements, and auxiliary prominences are provided on both sides of an inlet of the depression of the coupling elements.  
   
   
       4 . The pole guide as claimed in  claim 1 , wherein the flat panel is formed in shape of a square pillar.  
   
   
       5 . The pole guide as claimed in  claim 2 , wherein the flat panel is formed in shape of a square pillar.
