DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a weatherstrip structure for a door mounted around a door frame of an automobile.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 3, for example, a door 1 of an automobile is pivotally supported by a hinge (not shown) on one side (left side in the figure) with respect to an automobile body 2. When the door is closed, the door weather strip 4 (see FIG. 4) attached around the frame 3 of the door 1 is pressed against the frame 5 on the body side so that the vehicle compartment can be closed airtightly. I have. Here, as shown in FIG. 4 showing a cross section taken along line AA of FIG. 3, the door weather strip 4 is formed in a hollow shape so as to be able to elastically abut against the body frame 5. , One side edge has a protruding portion 4a which can be engaged with the engaging portion 3a provided on the door frame 3.

If the upper end width a and the lower end width b of the door 1 are greatly different from each other in the center pillar portion 6 as shown in FIG. 3, the door 1 is separated from the door weather strip 4. Is provided with a lip portion 7. Thereby, as for the center pillar portion 6, the weather strip 4 extends along the left side edge in FIG. 3, and the lip portion 7 extends along the right side end.

In this case, the lip 7 is bonded or mechanically attached to the inside of the door frame 3 as shown in FIG. In the corner portion shown, the tip 7a is overlapped with the weather strip 4 for a door as shown in FIG. At this time, since the tip of the lip portion 7 enters the inside of the weather strip 4 for a door as shown in FIG. 6 and overlaps with each other, it is possible to prevent water droplets such as rain from entering the inside from entering, and The area of the seam between the weatherstrip 4 for the door and the tip of the lip portion 7 is configured to smoothly transition.

[0005]

However, the weather strip 4 for a door having such a configuration is provided with a lip portion 7.
In the area of the seam, the continuous sealing property of the lip portion 7 is impaired, and the presence of the seam is visually recognized in the appearance,
There was a problem that the appearance was not good. In addition, since the door weather strip 4 and the lip portion 7 must be separately attached to the door frame 3 during assembly, there is a problem that assembly is troublesome and assembly time is relatively long. Was.

In view of the above, in the present invention, even when the widths of the upper end and the lower end of the center pillar are different, the sealability is not impaired, the appearance is improved, and the assembling is facilitated. It is an object of the present invention to provide a weatherstrip structure for a door.

[0007]

According to the present invention, a weather for a door is provided around a door frame constituting a door of an automobile and extends along one side edge of a center pillar portion. In a weather strip structure for a door including a strip and a lip portion extending along the other side edge of the center pillar portion, the door weather strip and the lip portion are joined at a joint region between the door weather strip and the lip portion. It is configured to be formed by integral molding.

According to the above construction, since the door weather strip and the lip are integrally formed, the sealing property is continuously maintained in the joint region, and the sealing property by the door weather strip is improved. improves. Further, since the seam region between the weatherstrip for the door and the lip portion is continuous, the seam is not visually recognized, and the appearance is improved. Further, since the weatherstrip for the door and the lip portion are integrated, there is no need to separately attach the door weatherstrip to the door frame as in the prior art. .

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail based on embodiments shown in the drawings. FIG. 1 shows an embodiment of a weatherstrip structure for a door according to the present invention. In FIG. 1, a weather strip structure 10 for a door is shown.
As in the prior art, the center pillar portion 6 of the vehicle shown in FIG. 3 is composed of a door weather strip 11 extending along a left edge and a lip portion 12 extending along a right end.

As shown in FIG. 2, the door weather strip 11 is formed in a hollow shape so as to be able to elastically abut against a body frame (not shown). And a protruding portion 11a that can be engaged with an engaging portion provided on the door frame.

The lip portion 12 is adhered or mechanically attached to the inside of the door frame, and at a corner portion indicated by reference numeral C in FIG.
As shown in the figure, the tip 12a is connected to the weather strip 11 for a door. Here, the connection portion 12b between the lip portion 12 and the weather strip 11 for the door is conventionally formed by the tip of the lip portion 12a having the weather strip 1 for the door.
Although they are configured so as to overlap with one, in the configuration according to the embodiment of the present invention, they are integrally formed.

The weatherstrip structure 10 for a door according to the present invention is configured as described above. Since the weatherstrip 11 for the door and the lip portion 12 are integrally formed at the connection portion 12b, the connection portion 12b, that is, the connection portion 12b is formed. In the seam region, the seam does not actually exist but is formed continuously. Therefore, the sealing performance in the joint region can be continuously maintained, and the sealing performance of the door weatherstrip structure 10 is improved.

[0013] In addition, since the joint is not visible in the joint area between the weatherstrip 11 for doors and the lip portion 12, the appearance is improved.

Further, since the door weather strip 11 and the lip portion 12 are integrally formed at the time of assembly, there is no need to separately assemble them to the body frame of the automobile, so that assembly is easy and short. And the assembling workability can be improved.

In the above embodiment, the door weatherstrip structure in the center pillar portion of an automobile door has been described. However, the present invention is not limited to this, and the present invention also relates to a door weatherstrip structure such as a rear door of an automobile. It is clear that can be applied.

[0016]

As described above, according to the present invention, since the weatherstrip for the door and the lip are integrally formed, the sealing property is continuously maintained in the joint region. In addition, the sealing performance by the weather strip for the door is improved. In addition, since the seam region between the weatherstrip for the door and the lip portion is continuous, the seam cannot be visually recognized, and the appearance is improved. Furthermore, since the weatherstrip for the door and the lip portion are integrated, it is not necessary to separately attach the door weatherstrip to the door frame as in the prior art, and the assembly can be performed easily and in a short time. Will be improved. Thus, according to the present invention, even when the widths of the upper end and the lower end of the center pillar portion are different, the sealability is not impaired, the appearance is improved, and the assembly is easily performed. An excellent weatherstrip structure for a door is provided.
