Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to a wind molding for an automobile.

[0002]

2. Description of the Related Art Among front windshields and rear windshields, particularly in the case of adhesive type windshields, a parting gap is generated between the peripheral edge of the windshield and the rising wall at the opening edge of the vehicle body. Therefore, the parting gap is closed with a wind molding to decorate the area around the attachment part of the wind glass. FIG. 8 shows such a conventional automobile wind molding, and in this figure, 20 is a wind molding. In this wind molding 20, the tip of a seal lip 22 protruding from a molding main body 21 fitted to the peripheral edge of the window glass 1 is engaged with an uneven portion 23 formed on the rising wall 8 at the opening edge of the vehicle body. (For example,
Japanese Utility Model Laid-Open No. 63-81710, Japanese Utility Model Laid-Open No. 63-8552.
(See Japanese Patent Publication No. 1).

[0003]

However, in such a prior art, due to the vibration of the vehicle body or the like, the window glass 1 and the rising wall 8 at the opening edge of the vehicle body are relatively opposed in the vertical direction in the figure. It has been pointed out that when the displacement occurs, the tip end portion of the seal lip 22 and the concave-convex portion 23 come into sliding contact with each other to generate a rubbing sound.

The present invention was devised for the purpose of solving the above problems.

[0005]

Means for Solving the Problems That is, the present invention relates to an automobile window molding provided with a molding body fitted to a peripheral edge of a window glass and a seal lip closely contacting a rising wall of an opening edge of a vehicle body, An arcuate portion is formed at the tip of the seal lip, and the arcuate portion and the seal lip base portion are connected by a flexible portion having low rigidity.

[0006]

When a relative displacement occurs between the window glass and the rising wall of the opening edge of the vehicle body due to vibration of the vehicle body or the like, the flexible portion of the seal lip flexibly deforms to absorb the vibration, and the seal lip is absorbed. The arcuate portion at the tip rolls into contact with the rising wall.

[0007]

Embodiments of the present invention will be described in detail below with reference to the drawings.

FIG. 1 is a sectional view of a mounting portion of an automobile window molding showing an embodiment of the present invention. In FIG. 1, reference numeral 1 is a window glass. The window glass 1 has a window molding 2 made of a resin material fitted around the periphery thereof, and the window molding 2 is bonded together with the window molding 2 by an adhesive 3.
(Fig. 2).

In the window molding 2, the groove portion 6 of the molding body 5 is fitted to the peripheral edge of the window glass 1, and the head portion 7 of the molding body 5 forms a parting gap between the peripheral portion of the window glass 1 and the rising wall 8. Is closed and the seal lip 9 is brought into close contact with the rising wall 8 of the vehicle body opening edge portion 4.

The seal lip 9 has an arcuate portion 10 formed at the tip thereof, and the arcuate portion 10 and the seal lip base portion 11 are connected by a flexible portion 12 having a low rigidity. The flexible portion 12
Is formed in a stepped shape so as to be thinner and have lower rigidity than the seal lip base portion 11 and the arc-shaped portion 10. Reference numeral 13 is a dam rubber made of rubber-like elastic material.

According to the structure of the above embodiment, when the relative displacement occurs between the window glass 1 and the rising wall 8 of the opening edge 4 of the vehicle body due to the vibration of the vehicle body or the like, the seal lip 9
The flexible portion 12 flexibly deforms to absorb the vibration, and the arcuate portion 10 at the tip of the seal lip 9 rolls and contacts the rising wall 8. Therefore, in the present embodiment, the tip of the seal lip 9 does not make sliding contact with the rising wall 8 and generate a rubbing noise.

3 to 6 show another embodiment of the present invention. As in these embodiments, the arc-shaped portion 10 at the tip of the seal lip 9 and the seal lip base portion 11 may be connected by the flexible portion 12 having low rigidity.

The shape of the flexible portion 12 is not limited to the shape of each of the above-described embodiments, but may be any shape having a rigidity lower than that of the seal lip base 11. Also, the arcuate portion 10
The cross-sectional shape thereof does not necessarily have to be a perfect circle, and may have a substantially arc shape that allows the rising wall 8 to come into contact with each other.

FIG. 7 shows another embodiment of the present invention. The arc-shaped portion 10 at the tip of the seal lip 9 is made of a resin material having a high friction coefficient (for example, chlorinated ethylene copolymer alloy), and The flexible portion 12 is made of a resin material softer than the seal lip base portion 11 (for example, PVC of HsA 60 ° or so).
Or foamed PVC).

Also in this embodiment, the flexible portion 12 having low rigidity is flexibly deformed to absorb the vibration, and the arcuate portion 10 makes rolling contact with the rising wall 8. The arcuate portion 10 and the flexible portion 12 may be formed of a material having a high friction material and a soft material (for example, a high polymerization degree PVC having a low permanent strain rate).

[0016]

As is apparent from the above description, the present invention is an automobile window molding provided with a molding body fitted to the peripheral edge of the windshield and a seal lip closely contacting the rising wall of the opening edge of the vehicle body. Therefore, by forming an arcuate portion at the tip of the seal lip and connecting the arcuate portion and the seal lip base portion with a low-rigidity flexible portion, the windshield and the vehicle body opening edge portion are separated due to vehicle body vibration or the like. Even if it is relatively displaced, the flexible part flexibly deforms and absorbs vibration, and the arcuate part rolls and contacts the rising wall, so the tip of the seal lip and the rising wall rub against each other. Does not occur with sound.
