Adjustable headrest bracket

Abstract

An adjustable headrest bracket includes a base and a coupling member located on the base. The coupling member has two coupling ends to couple with two separated headrest brackets. Each of the headrest brackets has an insertion end insertable into a vehicle seat and a hinge end coupled on the coupling end. Each of the headrest brackets forms a swivel path about the hinge end and a horizontal moving path relative to the coupling member. Thereby the interval of the headrest brackets can be adjusted to be inserted into different types of vehicle seats.

1 . An adjustable headrest bracket used on a headrest of a vehicle seat that has a display panel to be inserted in a corresponding insertion hole on the vehicle seat, comprising: 
 a base which is located in the headrest and holds the display panel;    a coupling member located on the base; and    two separated headrest brackets each having a hinge end coupled with the coupling member and an insertion end coupled with the vehicle seat, and forming a swivel path about the hinge end and a horizontal moving path relative to the coupling member.    
   
   
       2 . The adjustable headrest bracket of  claim 1 , wherein the coupling member is integrally formed on the base.  
   
   
       3 . The adjustable headrest bracket of  claim 1 , wherein each of the headrest brackets has a bending portion to divide the insertion end and the hinge end.  
   
   
       4 . The adjustable headrest bracket of  claim 1 , wherein the coupling member has two coupling ends to couple with the two hinge ends of the headrest brackets.  
   
   
       5 . The adjustable headrest bracket of  claim 4 , wherein each of the coupling ends has a coupling hole to receive the hinge end.  
   
   
       6 . The adjustable headrest bracket of  claim 4 , wherein the hinge end is a hinge hole, the coupling member being inserted into the hinge hole.  
   
   
       7 . The adjustable headrest bracket of  claim 1 , wherein the base has a confining hole on one side corresponding to the vehicle seat to limit the range of the horizontal moving path and the swivel path.  
   
   
       8 . The adjustable headrest bracket of  claim 1 , wherein each of the headrest brackets is coupled with a coupling duct which has an outer diameter corresponding to the insertion hole of the vehicle seat.  
   
   
       9 . The adjustable headrest bracket of  claim 8 , wherein the coupling duct has an anchor rib on an upper rim of the outer diameter.  
   
   
       10 . The adjustable headrest bracket of  claim 1 , wherein the headrest brackets are hollow and have respectively two openings to allow a power cord and signal line of the display panel to thread through.  
   
   
       11 . The adjustable headrest bracket of  claim 10 , wherein the coupling duct has a threading zone communicating with the openings of the headrest brackets and a threading opening communicating with the threading zone to receive the power cord and signal line.  
   
   
       12 . The adjustable headrest bracket of  claim 1 , wherein the coupling member has a plurality of anchor plates connected by a connection portion, the anchor plates being removable to allow the headrest brackets to mate the interval of the insertion hole of the vehicle seat.  
   
   
       13 . The adjustable headrest bracket of  claim 1 , wherein the coupling member includes two coupling sleeves located on the base.  
   
   
       14 . The adjustable headrest bracket of  claim 13 , wherein the coupling sleeves are integrally formed on the base.  
   
   
       15 . The adjustable headrest bracket of  claim 13 , wherein the coupling sleeves are spaced from each other at a distance such that the headrest brackets are held between them at a minimum interval.  
   
   
       16 . The adjustable headrest bracket of  claim 13 , wherein the coupling sleeves have a plurality of anchor plates connected by a connection portion, the anchor plates being removable to allow the headrest brackets to mate the interval of the insertion hole of the vehicle seat.  
   
   
       17 . The adjustable headrest bracket of  claim 13 , wherein the headrest brackets are hollow and have respectively two openings to allow a power cord and signal line of the display panel to thread through.
