Description

TECHNICAL FIELD The present invention relates to a method for manufacturing a weatherstrip molding which is attached to an elevating window portion of a vehicle.

[Conventional technology]

In the window of the vehicle, especially the window of the rear door, when the window glass is fully raised, the notch of the window glass corresponding to the wheel housing is raised to a position where it can be seen from the side of the vehicle. Therefore, weatherstrip moldings may be installed to cover the rear corners of the window to cover it or for design requirements. FIG. 9 is a side view of the vehicle, where 1 is the vehicle body and 2
Is a door, 3 is an elevating window glass, 4 is a weather strip molding, and is formed so as to cover the corner portion 5.

10 to 15 show a conventional weather strip molding, FIG. 10 is an overall perspective view, FIG. 11 is a perspective view of a seal member, and FIG. 12 is a perspective view of a finisher.
13 is a cross-sectional view of the metal profile, FIG. 14 is a sectional view taken along the line AA of FIG. 11, and FIG. 15 is a sectional view taken along the line BB of FIG.
The molding 4 joins the metal profile 6 attached to the upper edge of the vehicle body panel and the seal member 8 having the lip 7 by caulking, and the corner portion 5 is a separately manufactured finisher 9 as a complete product. It is joined with. Finisher 9 of seal member 8
After forming the cutout portion 8a, the portion corresponding to 2 is bent to form the resin portion 8d and the attachment portion 8c.

In general, as the weather strip molding, a metal profile 6 in which a lip 7 is integrated by extrusion molding is often used. However, since such a profile extrusion material is difficult to bend so as to cover the corner portion 5,
Conventionally, as shown in the drawing, the finisher 9 which is a separate member is joined. In this case, if a lip is formed on the finisher 9, the lip 7 cannot be integrated with the lip 7 of the main body. Therefore, the lip 7 is formed on a seal member 8 different from the metal profile 6, and the lip 7 is formed on the notch portion 8a and the resin portion as described above. After post-processing such as formation of 8b, the whole was joined.

However, in such a conventional weatherstrip molding, the number of parts and the number of work steps are large, and the quality is not constant due to variations in assembly, and
There is a problem that an excellent appearance cannot be obtained.

As a means for improving such a point, JP-A-56-79020
In No. 2, only the lip 7 at the end of the profile extruded material in which the lip 7 is extruded on the metal profile 6 is cut, and a second lip in which only the height of the tip is gradually increased is formed on the cut portion by injection molding. A method of integrally forming has been proposed.

However, since the weather strip molding manufactured by such a method covers the cutout portion of the elevating window glass only by the second lip whose tip height gradually increases, the shape retention performance of the second lip is improved. There is a problem in that there is instability, the exposed area becomes large, and a strange feeling is likely to occur.

[Problems to be Solved by the Invention]

The present invention is for solving the above conventional problems, and it is possible to provide a weather strip molding having no assembly variation and an excellent appearance with a small number of parts and man-hours and a simple operation. The purpose is to propose a method that can be manufactured.
