Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to improvements in a rear window weather strip used as a rear window seal for automobiles, particularly hatchback type automobiles.

Recently, especially in hatchback type automobiles, the shape of the lower part of the rear window (back door window), that is, the shape of the rear window weather strip 1, has been changed to a second shape in order to reduce the air resistance value during driving.
As shown in the figure, the shape is changing to what is called a spoiler. To be more specific, FIG. 2 is an example of a cross section taken along the line -- in FIG. In addition to a panel fitting groove 3 formed in the lip body 2 and a glass fitting groove 4 into which the rear window glass (back door window glass) 11 is fitted, there is also a spoiler which extends toward the outside of the outer panel 10a. The protrusion 5 is integrally formed. And this spoiler protrusion 5
An inner lip 6 that presses against the outer panel 10a is integrally formed on the lower surface of the base of the spoiler protrusion 5 and the inner lip 6 when the weather strip 1 is installed in the correct position as shown in the figure. A substantially V-shaped space S exists between them.

However, in an automobile having a weather strip with a spoiler as described above, when closing the back door 10, the spoiler protrusion 5 may be pushed as shown by arrow F in FIG. In this case, the entire upper half of the weather strip 1 including the spoiler protrusion 5 is lifted up as shown by the imaginary line in FIG. 2, and the lip 7 of the glass fitting groove 4 holding the rear window glass 11 is Since a so-called opening phenomenon occurs, there is a problem in that the sealant 8 filled in the glass fitting groove 4 protrudes outside.

The present invention has been made in view of the above points, and its purpose is to prevent the deformation that causes the above-mentioned mouth opening phenomenon by increasing the rigidity of the spoiler protrusion.

For this purpose, the first feature of the present invention is to increase the rigidity of the spoiler projection by forming the base of the spoiler projection as thick as possible. If only the weather strip is increased, the deformation of the weather strip in its free state will be restricted and installation workability may be hindered.In order to satisfy both of these requirements at the same time, it is necessary to make the weather strip thick as described above. At the same time, a notch is formed between the spoiler protrusion and the inner lip.

Hereinafter, embodiments of the present invention will be described in detail based on the drawings.

FIG. 3 shows one embodiment of the present invention, and the same parts as those in FIG. main body, 1
0a and 10b are outer and inner panels constituting the back door panel 10, 11 is a rear window glass, and the weather strip main body 21 includes the outer panel 10.
the spoiler protrusion 2 so as to extend to the outside of a
5 are integrally formed. This spoiler protrusion 2
5 is made as thick as possible by building up so that the upper surface side has a smooth arcuate curved surface compared to the conventional shape, and the free end 25a of the spoiler portion 25 and the panel contact portion 29 and the arcuate curved surface 3
0, the spoiler protrusion 25 is formed into a substantially scalene triangular shape as a whole including an inner lip 26 which will be described later. By forming a notch 31 substantially parallel to the glass fitting groove 4 in the panel abutting portion 29, an inner lip 26 is formed separately and independently on the lower surface of the spoiler protrusion 25 near its base. As a result, the inner lip 26 is configured to be elastically deformable from its base 26a.
When the weather strip 20 is in a free state, the cut 31 is opened so that the spoiler protrusion 25 and the inner lip 26 are separated from each other as shown in FIG.

In the above configuration, when the rear window weather strip 20 is in the normal installed state as shown in FIG. 3, the notch 31 is closed and the spoiler protrusion 25 and the inner lip 26 are in close contact with each other. At the same time, by making the thickness of the back side of the spoiler protrusion 25 as large as possible than before, the spoiler protrusion 25 has sufficient rigidity. Even if an external force acts, the glass fitting part 4
There is no deformation such as opening the mouth.

Furthermore, by increasing the rigidity of the spoiler protrusion 25 as described above, there is a risk that the reaction force of the inner lip 26 when installing the weather strip will increase and the installation workability will be reduced. By forming the notch 31, the inner lip 26 can be easily deformed in the free state, so the above-mentioned concerns are eliminated and the same installation workability as in the past can be maintained. In addition, in the above-mentioned normal installation state, the notches 31 are in complete contact with each other, and the spoiler protrusion 25 and the inner lip 26 appear to be integrated, so there is no risk of spoiling the appearance. do not have.

FIG. 5 shows another embodiment of this invention,
The structure is the same as that of the first embodiment except that a protrusion 32 is provided on the spoiler protrusion 25 side or the inner lip 26 side in the notch 31. In the case of this embodiment, a reaction force is generated due to the provision of the protrusion 32, and the pressing force of the lip 27 against the rear window glass 11 increases, so in addition to the above-mentioned effects, the sealing performance of the rear window glass 11 is improved. There are advantages to doing so.

As is clear from the above description, according to the present invention, the rigidity of the spoiler protrusion is increased by forming the wall thickness of the spoiler protrusion as large as possible, so even if an external force is applied to the spoiler protrusion, Even if this happens, there is no risk of deformation that would reduce the inherent sealing performance of the weather strip. In addition, as mentioned above, by increasing the thickness of the spoiler protrusion and at the same time making a cut in a part of the spoiler protrusion to form the inner lip independently, the inner lip can bend freely in the free state. Therefore, the workability during installation is not hindered, and the above-mentioned notch is closed in the normal installation state, so there are effects such as improving the external appearance.
