## Title
Tailgate for vehicle

## Abstract

A tailgate for a vehicle includes an upper panel having a shape such that it acts as a spoiler, and a lower panel attached to the upper panel. The lower panel may define a windshield mounting hole. The lower panel may include two side pillars and an upper crossing member, the side pillars and upper crossing member defining the windshield mounting hole. The upper crossing member and the side pillars may be welded to the upper panel.

## Background
CROSS-REFERENCE TO RELATED APPLICATIONS
The present application is based on, and claims priority from, Korean Application Serial Number 10-2007-0110153, filed on Oct. 31, 2007, the disclosure of which is hereby incorporated by reference herein in its entirety.
FIELD OF THE INVENTION
The present invention relates to a vehicle tailgate.
BACKGROUND OF THE INVENTION
A spoiler is generally fixed to an upper portion of a vehicle tailgate. A typical spoiler is made of plastic, and is separately formed by injection molding and then mounted on the vehicle. This provides manufacturing difficulties and is costly.
SUMMARY OF THE INVENTION
A tailgate for a vehicle includes an upper panel having a shape such that it acts as a spoiler, and a lower panel attached to the upper panel. The lower panel may define a windshield mounting hole. The lower panel may include two side pillars and an upper crossing member, the side pillars and upper crossing member defining the windshield mounting hole. The upper crossing member and the side pillars may be welded to the upper panel.



BRIEF DESCRIPTION OF THE DRAWINGS
For a better understanding of the nature and objects of the present invention, reference should be made to the following detailed description with the accompanying drawings, in which:
FIG. 1 is a front view of an upper panel of a tailgate according to an embodiment of the present invention;
FIG. 2 is a cross-sectional view taken along a line III-III of FIG. 1:
FIG. 3 is a front view of a lower panel of the tailgate according to an embodiment of the present invention; and
FIG. 4 is a view showing the tailgate for a vehicle according to an embodiment of the present invention.



DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
A preferred embodiment of the present invention will be described below with reference to accompanying drawings.
Referring to FIGS. 1 to 4, a tailgate according to an embodiment of the present invention includes an upper panel 5 and a lower panel 7. Upper panel 5 forms an upper portion of tailgate 1, and is positioned above a rear windshield glass-mounting hole 3 in tailgate 1. Upper panel 5 has a shape such that it itself acts as a spoiler. Lower panel 7 is fixed to the lower portion of upper panel 5, to form tailgate 1.
It is preferred that upper panel 5 and lower panel 7 are separately formed, because a depth S for forming the shape of the spoiler shown in FIG. 2 is considerably large. For this reason, unless upper panel 5 and lower panel 7 are separately formed, there may be problem in that a spoiler-shaped portion 9 is torn. However, the present invention is not limited to separately made panels 5, 7.
Lower panel 7 includes two side pillars 11 and an upper crossing member 13, which are integrally formed with each other, so as to define rear windshield glass-mounting hole 3.
That is, in some embodiments, rear windshield glass-mounting hole 3 is not formed by upper panel 5, but is completely defined by the lower panel 7. Accordingly, lower panel 7 is strong, and is easily handled during the manufacture of tailgate 1.
Upper crossing member 13 and the upper portions of the two side pillars 11 of lower panel 7 may be welded to upper panel 5.
According to the above-mentioned tailgate 1 for a vehicle, since spoiler-shaped portion 9 is simultaneously formed during the formation of upper panel 5, a separate part does not need to be manufactured and assembled. Therefore, it is possible to reduce the manufacturing cost of the vehicle.
While this invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.

## Claims

1. A tailgate for a vehicle, comprising:
an upper outer panel positioned above a rear windshield glass-mounting hole of the vehicle and having a spoiler monolithically formed with the upper outer panel and protruding from an upper portion of the upper outer panel in a rearward direction of the vehicle and returning to a lower portion of the upper outer panel, whereby the spoiler forms an open channel in the upper outer panel; and
a lower outer panel separately formed from the upper outer panel and welded to the upper outer panel;
wherein the lower outer panel comprises two side pillars and an upper crossing member, the side pillars and the upper crossing member defining the windshield mounting hole; and
wherein the open channel of the upper outer panel opens toward an outer surface of the lower outer panel.

2. The tailgate as defined in claim 1, wherein the lower outer panel defines the windshield mounting hole.

3. The tailgate as defined in claim 1, wherein the lower outer panel surrounds the windshield mounting hole on all sides.

4. The tailgate as defined in claim 1, wherein the upper crossing member and the side pillars are welded to the upper outer panel.

5. A tailgate for a vehicle, comprising:
an upper outer panel positioned above a rear windshield glass-mounting hole of the vehicle and including a protruding portion protruding from an upper portion of the upper outer panel in a rearward direction along a transverse direction of the vehicle and returning to a lower portion of the upper outer panel, whereby the protruding portion forms an open channel in the upper outer panel; and
a lower outer panel separately formed from the upper outer panel and fastened to the upper outer panel, wherein the lower outer panel defines the windshield glass-mounting hole to receive a windshield glass therein; and
wherein the open channel of the upper outer panel opens toward an outer surface of the lower outer panel.

6. The tailgate as defined in claim 5, wherein the lower outer panel includes an upper crossing member disposed at an upper middle portion of the upper outer panel to support the upper outer panel.
