Description

[0001]
[Industrial application fields]
The present invention relates to a weather strip attached to a flange of a vehicle body opening such as a door.
[0002]
[Prior art]
As shown in FIG. 4, a weather strip 8 in which a welt 7 having a substantially U-shaped cross section is sandwiched between a flange F of a vehicle body opening such as a door is provided between an interior trim M and a base end of a vehicle interior side wall portion 7 a. An interior lip 9 to be sealed is provided in a projecting manner, and a hollow seal portion 10 that is elastically contacted with the door D is provided on the vehicle outer side wall portion 7b.
[0003]
[Problems to be solved by the invention]
However, the interior lip 9 is designed to have a very soft surface by applying a decorative film 9a on the surface, for example, applying a cloth or wrapping a color sponge or color solid to improve the appearance. Accordingly, when the products are stacked as shown in FIG. 5 at the time of shipment, etc., the solid material of the inner side wall portion 7a of the welt 7 of the upper weather strip 8 as shown in FIG. There is a problem that the hard opening end 7c hits to generate a presser bar S or blackening K as shown in FIG. 6 (b).
Therefore, in view of the conventional problems, the present invention has an object to provide a weather strip that prevents a flaw such as a presser bar from being generated on the surface of a soft interior lip when products are stacked at the time of shipment. And
[0004]
[Means for Solving the Problems]
In order to achieve such an object, as shown in FIGS. 1 and 2, the configuration of the present invention is an interior in which a decorative coating 3a is formed on the base end of a vehicle interior side wall 2a of a welt 2 having a substantially U-shaped cross section. In the weather strip 1 in which the lip 3 is protruded and the hollow seal portion 5 is provided on the vehicle outer side wall portion 2b, a flexible portion 4 made of a synthetic rubber sponge is provided at the opening end of the vehicle inner wall portion 2a of the welt 2. When the product is stacked, even if the opening end of the inner side wall 2a of the upper weather strip hits the decorative coating 3a of the interior lip 3 of the lower weather strip 1, the decorative coating 3a may be damaged. it is obtained as no.
[0005]
【Example】
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In FIG. 1, reference numeral 2 denotes a welt having a generally U-shaped cross section of the weather strip 1, and an interior lip 3 is projected from the base end of the vehicle interior side wall 2a. A decorative coating 3a is provided on which a sponge or color solid is wound. A flexible portion 4 made of a sponge made of synthetic rubber (EPDM) is attached to the opening end of the vehicle interior side wall portion 2a. The welt 2 has a hollow seal portion 5 (not shown) protruding from the vehicle outer wall portion 2b, and a cored bar 6 is embedded.
[0006]
When a large number of weather strips 1 are stacked as shown in FIG. 5 at the time of shipment or the like, the inner wall of the upper welt 2 is applied to the decorative coating 3a of the interior lip 3 of the lower weather strip 1 as shown in FIG. Although the flexible part 4 of the part 2a hits with its own weight, the change in the surface pressure has a mountain shape whose peak is not high as shown in the graph G. On the other hand, as shown in FIG. 3, the peak of the surface pressure graph g in the case where the solid material on the upper inner wall 7a directly hits the decorative coating 9a of the lower interior lip 9 is very high. Therefore, in the case of FIG. 2, the surface pressure is remarkably low, and the presser bar and darkening do not occur as in the conventional case.
[0007]
【The invention's effect】
As described above, the weather strip of the present invention is provided with the flexible portion of the sponge material at the opening end of the inner wall of the welt, so that when the product is stacked at the time of shipment, etc. Even if the opening end of the inner wall of the upper weatherstrip hits the decorative film on the lip, the surface pressure does not increase, and there is no problem that the decorative film of the lower interior lip is damaged like a presser bar as in the past. .
