Adjustable headrest bracket
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.
The present invention relates to a headrest bracket and particularly to an adjustable headrest bracket adaptable to a wide variety of vehicle seats.
BACKGROUND OF THE INVENTION The vehicle industry is thriving and the interior design of the vehicles is versatile these days. Vehicle seats also have many different selections. Nowadays many headrests or vehicle seats adopt various designs to accommodate audiovisual equipment to provide desired entertainments for users. The conventional headrest bracket as shown in
To remedy the aforesaid problem, adjustable headrest brackets have been developed that have an adjustable interval to facilitate installation on the vehicle seats. One example is R.O.C. patent publication No. 372507 entitled “Adjustable vehicle headrest” as shown in
The conventional headrests mentioned above cannot be adapted easily to different types of vehicle seats. Adjusting the interval of the insertion rods is especially difficult. How to make the headrest bracket modularized to reduce fabrication cost is an issue remained to be overcome in the industry.
SUMMARY OF THE INVENTIONThe primary object of the present invention is to solve the aforesaid disadvantages. The present invention provides an adjustable headrest bracket installable on the headrest of a vehicle seat. It has 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 coupling with the coupling end. The headrest bracket forms a swivel path about the hinge end and a horizontal moving path relative to the coupling end. The interval of the two headrest brackets can be altered easily without using any hand tool and installed on a vehicle seat.
Another object of the invention is to protect a power cord and signal line of a display panel. The base holds a display panel. The headrest bracket has a threading zone to allow the power cord and signal line to be threaded through. Hence the power cord and signal line are not exposed. Wiring of the power cord and signal line is more convenient.
The foregoing, as well as additional objects, features and advantages of the invention will be more readily apparent from the following detailed description, which proceeds with reference to the accompanying drawings.

In the embodiments set forth above, the headrest brackets 22 may also have latch notches 224 formed thereon corresponding to the insertion holes 50 to adjust the elevation of the headrest 1 according to user's requirement. The headrest brackets 22 can be moved in the insertion holes 50 and latched on the latch notches 224 at a desired elevation. This technique is known in the art, hence details are omitted.
While the preferred embodiments of the invention have been set forth for the purpose of disclosure, modifications of the disclosed embodiments of the invention as well as other embodiments thereof may occur to those skilled in the art. Accordingly, the appended claims are intended to cover all embodiments which do not depart from the spirit and scope of the invention.
Claims
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.
