DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle window molding.

[0002]

2. Description of the Related Art When a vehicle travels in rainy weather, rainwater adhering to a window glass of the vehicle may flow laterally to a side glass to deteriorate visibility. For this reason, conventionally, the wind molding is composed of an upper molding, left and right side moldings, and a corner molding that joins them, for a total of five parts. A guide groove forming a weir for draining is formed in the side molding, and rainwater flowing toward the side edge of the window glass is guided upward or downward of the window glass by the guide groove. Was common. In such a vehicle window molding, not only the number of parts and the number of assembling steps are increased, but also because the upper molding and the left and right side moldings have different cross-sectional shapes, they must be formed by separate extrusion dies. No. Further, in corner molding, usually, molding must be performed by press molding. For this reason, the cost of manufacturing and assembling the wind molding increases.

[0003] In order to reduce the number of components of a wind molding to reduce the cost of manufacture and assembly, for example, one disclosed in JP-A-63-212121 is known. In this case, a molding body of an extruded product having an upper molding part, a corner molding part and both side molding parts continuously and integrally, and a back side of a decorative lip (a ridge) of a side molding body of the molding body are provided. A window molding is constituted by a draining member (injection molding portion) which projects the decorative lip outward from the window glass surface to form a weir for draining. Simultaneously with the extrusion molding of the molding body, a cut groove is formed in the back surface of the decorative lip over the upper molding, the corner molding part and both side molding parts. Then, on the back of the decorative lip in the side molding portion of the molding body, the decorative lip is opened at the cut groove portion, and the drainage member (injection molded portion) is fixed so as to engage with the cut groove. ing.

[0004]

By the way, in the prior art described above, when the molding body is mounted in the gap between the window opening of the vehicle body panel and the window glass, the gap is formed in the corner molding portion of the molding body. Is fitted while being bent along the corner portion. At this time, the stress due to the bending acts intensively on the cut groove on the back surface of the decorative lip of the corner molding. As a result, the decorative lip of the corner molding portion undulates inside the cut groove (at the tip side of the decorative lip). Then, a gap is formed between the decorative lip and the window glass due to the waving of the decorative lip, which causes poor sealing and a problem that the appearance is deteriorated.

SUMMARY OF THE INVENTION In view of the above-mentioned conventional problems, an object of the present invention is to provide a wind molding for a vehicle which can prevent waving deformation caused by a cut groove on a back surface of a decorative lip in a corner molding portion of a molding body. It is to be.

[0006]

In order to achieve the above object, a vehicle wind molding according to the present invention is provided.
A window opening for a vehicle body panel, an upper portion between a window glass attached to the window opening, an upper corner portion, and a vehicle window molding that is fitted in a gap on both left and right sides to cover the gap, A molding body having an upper molding portion, a corner molding portion and both side molding portions continuously and integrally having a supporting leg fitted into the gap and a decorative lip extending from the supporting leg toward the window glass surface. Is extruded at the same time as the molding
The back of the decorative lip in the corner molding part of the main body
The cut groove is formed only on the back surface of the decorative lip of the side molding portion without being formed with the cut groove , and further, the cut groove is formed on the back side of the decorative lip of the side molding portion. There is provided a draining member which bends the decorative lip with the thinned portion as a fulcrum and projects from the window glass surface by a predetermined height to form a guide groove for draining.

[0007]

In the vehicle window molding constructed as described above, the molding body is fitted on the support legs between the upper and lower corner portions and the left and right grooves between the window opening of the vehicle body panel and the window glass. It is inserted and attached. In the side molding portion of the molding body, the decoration lip is smoothly bent and deformed by a draining member attached to the back surface of the decoration lip with the portion made thin by the cut groove on the back surface as a fulcrum, and from the window glass surface It is protruded by a predetermined height. Therefore, a guide groove for draining is formed well by the window glass surface, the draining member, and the decorative lip of the side molding portion. For this reason, the rainwater flowing toward the side edge of the window glass is guided upward or downward by the guide groove, thereby preventing the rainwater from flowing sideways to the side glass.

[0008] In the corner molding portion of the molding body, it is fitted while being bent along the upper corner portion of the gap. Since the cut groove is not formed on the back surface of the decorative lip of the corner molding portion, when the corner molding portion is bent, stress is locally concentrated on the back surface of the decorative lip of the corner molding portion. It is prevented from working. Therefore, the decorative lip of the corner molding portion is smoothly bent along the corner portion of the gap without waving.
