Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a weather strip for use in automobiles.

[Prior Art] FIG. 1 shows an automobile sunroof 1 having an opening that is opened and closed by a slide panel 2.
There is a weather strip 3 on the outer periphery of the slide panel 2.
is installed.

FIG. 5 shows a cross section of the weather strip 3 at the rear edge of the slide panel 2. As shown in FIG. The edge of the slide panel 2 has a vertical surface 21 and a receiving surface 22 formed in a step shape. A weather strip 3 is attached to this receiving surface 22.

The weather strip 3 is made of rubber or synthetic resin, and includes a base 31 and an upright part 32 rising from one end thereof. It is fixed.

At the upper end of the upright portion 32, a first seal lip 33 that contacts the upper surface of the edge of the slide panel 2 and a roof 1 are provided.
A second sealing lip 34 is formed which contacts the lower surface of the end of the tube. Further, a third sealing lip 35 is formed at the end of the base 31 and comes into contact with the lower surface of the roof 1.

FIG. 4 shows the weather strip 3 before assembly, and the upright portion 32 is the vertical surface 21 (see FIG. 5).
It stands up in the direction of inclination toward the side, and when assembled, the upright portion 32 and the first seal lip 33 are pressed against the slide panel 2 to improve sealing performance.

The second sealing lip 34 generally has a substantially V-shaped cross section with a root portion 341 that gradually slopes downward and then bends upward again. As a result, the base portion 341 is easily bent downward, preventing an increase in the closing force of the slide panel 2, and when the slide panel 2 is closed, the reaction force of the roof 1 is applied to the slide panel 2 via the second seal lip 34. is pushed down to prevent a difference in level from occurring between the roof 1 and the slide panel 2.

On the other hand, a flange 41 is formed at one end of the holder plate 4 and stands upright at a right angle. this is,
The holder plate 4 is a thin metal plate of about 1 mm and has low rigidity. When the bolt 5 is tightened, the holder plate 4 tends to bend in a wave-like manner. To prevent this, the holder plate 4 is provided with rigidity by a flange 41.

[Problems to be Solved by the Present Invention] By the way, when the weather strip 3 is assembled as shown in FIG. 5 in the state shown in FIG. It is pushed and tries to stand upright with respect to the base 31, but at that time, the root part 341 of the second seal lip 34 is hooked on the flange 41 of the holder plate 4, and the tip of the lip 34 is shaped into a predetermined shape. Otherwise, there is a risk that the sealing force will be reduced.

In order to prevent this, a means is taken to adhere the weather strip 3 to the entire surface of the holder plate 4, including the flange 41, as shown in FIG. However, this method has the following problems.

That is, as shown in FIG.
is attached to the slide panel 2 at a position with some margin between the upright portion 32 and the vertical surface 21 of the slide panel, taking into account variations in the shape of the edge of the slide panel 2 and the cross-sectional shape of the weather strip 3. A gap 6 is created between the two, and the first seal lip 33 is in a floating state, resulting in a decrease in sealing performance.

This idea was made in view of the above circumstances.
To provide a weather strip that does not cause the second seal lip 34 to get caught as described above when the weather strip 3 is assembled, and maintains good sealing performance by using the pressing force of the upright portion 32, thereby solving the conventional problems. The purpose is to solve the following points.

[Means for Solving the Problems] The weather strip of the present invention has a base portion 3 on the bottom surface of the second seal lip 34, as shown in FIG.
A rib 36 is formed that projects downward from the lower end of the weather strip 41, and the rib 36 is engaged with the flange 41 of the holder plate 4 on the surface opposite to the upright portion 32 of the weather strip 3, and in this engaged state, the above-mentioned A feature is that a distance is maintained between the flange 41 and the upright portion 32.

[Operation and Effect] By providing the rib 36 as described above, when assembling the weather strip, the upright portion 32 is attached to the flange 4 of the second seal lip 34 as shown in FIG.
1, and the upright portion 32 is pressed against the vertical surface 21 of the slide panel 2 by the pressing force, and the first seal lip 33 is also brought into close contact with the slide panel 2, resulting in a good sealing force. .

[Embodiment] Hereinafter, an embodiment of the present invention will be described with reference to FIGS. 1 to 3, focusing on the differences from the conventional structure described above.

As shown in FIG. 2, a standing portion 32 stands up in an inclined direction from one end of the base 31 of the weather strip 3.
The upper end has a first sealing lip 33 facing outward and a second sealing lip 34 facing inward.
stands out. A third sealing lip 35 extends from the other end of the base 31.

The second seal lip 34 has a base portion 341 having a substantially V-shaped cross section, a tip end extending obliquely upward, and a tip end directed downward again.

A holder plate 4 is adhered to the upper surface of the base 31, and a flange 41 stands up from one end of the holder plate 4 on the side of the upright portion 32 in a right angle direction.

On the lower surface of the second seal lip 34, a rib 36 projects downward from the lower end of the V-shaped root portion 341. Then, raise the upright portion 36 in a slightly upright direction, and place the rib 36 against the upright portion 32 against the flange 41.
The rib 36 is positioned on the opposite side from the flange 41 and the rib 36 is engaged with the flange 41 by the reaction force of the upright portion 32. In this state, a gap is maintained between the flange 41 and the upright portion 32.

As shown in FIG.
It is assembled by fastening it to the receiving surface 22 of the slide panel 2 at. At this time, the upper part of the upright part 32 is pushed by the vertical surface 21 of the slide panel 2, so that it is further pushed in the upright direction, and the upper part of the upright part 32 is pressed against the vertical surface 21 due to the reaction force, and at the same time the first seal lip is pressed. 33 is pressed against the upper surface of the rear end of the slide panel 2. Note that at this time, the rib 36 separates from the flange 41.

Therefore, in the weather strip of the present invention, the flange 41 of the holder plate 4 is positioned closer to the upright portion 32 than the lower end of the root portion 341 of the second seal lip 34 by the rib 36, and the flange 41 of the holder plate 4
Since the distance between the base portion 32 and the standing portion 32 is maintained so that the standing portion 32 can further stand up, the base portion 34 is
1 does not interfere with the flange 41,
Also, during assembly, the upper end of the upright portion 32 and the first seal lip 33 are attached to the upright portion 32 on the slide panel 2.
The reaction force creates pressure contact and provides excellent sealing force.
