Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a method for connecting a glass run attached to a vehicle door to a belt line weather strip.

[0002]

2. Description of the Related Art As shown in FIG. 3 and FIG. 4, a glass run 3 for guiding a sliding door glass G ascending and descending is fitted on a door sash 2 of a side door (a front door or a rear door) 1 of a vehicle. A belt line weather strip 6 for guiding the sliding door glass G is attached to the flange 8 on the belt line 4 of the side door 1. 6A shows a belt line weather strip (belt line inner) on the indoor side, and 6B shows a belt line weather strip (belt line outer) on the outdoor side. FIG. 4 is an enlarged sectional view taken along line AA of FIG.

Conventionally, the glass run 3 and the belt line weather strip 6 are connected to each other as shown in FIGS. 5 and 6 (enlarged sectional view taken along the line BB in FIG. 5).
a and 6a are connected by molding in a state where they abut each other. FIG. 5 is a perspective view showing the glass run 3 and the belt line weather strip 6 connected by the connection method according to the conventional example, and is an enlarged perspective view of a portion corresponding to the X portion shown in FIG.

[0004]

However, in the conventional example, the end portions 3a and 6a connected by molding are face-to-face but face to face, and only the boundary surface is formed by molding. The strength of the part is insufficient. Therefore, since the metal core material 9 is embedded in the belt line weather strip 6 and is heavy, the glass run 3
When the belt line weather strip 6 is connected to the belt, peeling may occur at the connection portion. In addition, although the molding of the connection boundary surface is performed over a small range, there is a problem that a surface difference or a level difference is generated and the appearance is poor.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a method for connecting a glass run and a belt line weather strip which can improve the strength of a connecting portion and improve the appearance.

[0006]

In order to achieve the above object, a method for connecting a glass run to a belt line weather strip according to the present invention is a sliding door glass (2) fitted to a door sash (2) of a vehicle and raised and lowered. In a method for connecting a glass run (3) for guiding the glass door (G) and a belt line weather strip (6) attached to the belt line (4) and also for guiding the sliding door glass (G), a molding material is used at the time of molding. Are overlapped from the glass run (3) side so as to pass over the end (6a) of the belt line weather strip (6) and enter the belt line weather strip (6) side, and the part (P) is formed into a smooth step portion. The connection is achieved by molding.

The symbols in the parentheses correspond to the symbols described in the drawings and the embodiments of the invention described later.

According to the present invention, the connection between the glass run and the belt line weather strip is not limited to the contact surface between the ends of the glass run and the belt line weather strip as shown in the conventional example, but the belt line is connected from the glass run side to the belt line. The strength of the connection between the glass run and the beltline weatherstrip is improved because it is performed by an overlapped molded part that extends beyond the end of the weatherstrip and into the beltline weatherstrip side. In addition, the overlapped portion is not flush with the external surface of the belt line weather strip, but is molded so that there is a smooth step from the initial stage. Good looking.

[0009]

Embodiments of the present invention will be described with reference to the drawings. The same parts as those in the conventional example are denoted by the same reference numerals, and description thereof is omitted. FIG. 1 is a perspective view showing a glass run and a belt line weather strip connected by a connection method according to an embodiment of the present invention.
FIG. 4 is an enlarged perspective view of a portion corresponding to an X part shown in FIG. FIG. 2 is an enlarged sectional view taken along line CC of FIG.

A method for connecting a glass run to a belt line weather strip according to an embodiment of the present invention is a glass run 3 fitted on a door sash 2 of a vehicle and guiding a sliding door glass G to go up and down, and attached to a belt line 4. In the method of connecting the belt line weather strip 6 which also guides the sliding door glass G, a rubber material which is a molding material at the time of molding is transferred from the glass run 3 side to the end portion 6a of the belt line weather strip 6 so as to form a belt. A connection is made by overlapping the overlapping portion P so as to enter the line weather strip 6 side and forming the overlapped portion P into a smooth step portion so as to be lower from the glass run 3 side to the belt line weather strip 6 side. It is. The lip 3A on the indoor side of the glass run 3 is overlapped with a belt line weather strip (belt line inner) 6A on the indoor side by molding, while the lip 3B on the outdoor side is a belt line weather strip on the outdoor side. Belt line outer) 6B is overlapped by molding.

In a cavity of a mold (not shown), a space in which a molding member used for molding and connecting the belt line weather strip 6 to the glass run 3 can be overlapped and a step can be formed as described above. The glass run 3 and the belt line weather strip 6 are pressed and positioned by a metal mold so that the groove is provided.

As described above, the molding connection by the molding member is performed by the glass run 3 and the belt line weather strip 6.
The strength of the connecting portion between the glass run 3 and the belt line weather strip 6 is improved because it is performed not only by the contact surface between the end portions but also by the overlapped portion P. Even if the weight increases due to the core material 9 and the load applied to the connecting portion increases, the peeling does not easily occur. Further, the overlapped portion P is not flush with the external surface of the belt line weather strip 6, but is molded so as to have a step portion which is smoother than the initial stage, and is formed like a design line. So it looks good on the outside.

[0013]

As described above, according to the present invention, the connection between the glass run and the belt line weather strip is not limited to the contact surface between the ends of the glass run and the belt line weather strip as shown in the conventional example. The strength of the connection between the glass run and the belt line weather strip is improved because the overlap is performed by the overlapped molded portion so as to extend from the glass run side to the end of the belt line weather strip and enter the belt line weather strip side. Therefore, even if the metal core material embedded in the belt line weather strip increases the weight and increases the load applied to the connecting portion, the peeling does not easily occur.

The overlapped portion is not formed flush with the external surface of the belt line weather strip, but is molded so as to have a smoother step than the initial stage. It looks good in appearance.
