Description

[0001]
[Industrial application fields]
The present invention relates to an opening seal that is sandwiched between inner peripheral edges of a door opening of an automobile.
[0002]
[Prior art]
As shown in FIG. 5, an opening seal 9 having a U-shaped cross section that is sandwiched by a flange F indicated by a chain line at the inner peripheral edge of a door opening portion having a small R at the upper part of the center pillar of the vehicle is a hollow that elastically contacts the door when closed. An interior lip 11 is provided to cover the seal portion 10 and the end of the interior material (not shown). When the opening seal 9 is attached to the corner portion of the door opening, the tip of the interior lip 11 is deformed and does not cause a gap at the end of the interior material. Therefore, as shown in FIG. A support plate 12 integrally formed in the vicinity is molded to increase the rigidity near the base of the interior lip 11.
[0003]
[Problems to be solved by the invention]
However, as described above, the interior lip 11 and the vicinity of the base of the interior lip 11 are molded so that there is a problem that the cost is increased.
Therefore, in view of the conventional problems, the present invention can reinforce the rigidity near the base of the interior lip without molding the interior lip, and can reliably join the tip to the end of the interior material without any gaps. An object is to provide an opening seal.
[0004]
[Means to solve the problem]
In order to achieve such an object, as shown in FIGS. 1 to 4, the first configuration of the present invention is provided on the vehicle outer side wall 3 of the seal body 2 having a U-shaped section sandwiched between the inner peripheral edges of the door opening. A hollow seal portion 4 that elastically contacts the door when closed is provided, and a base of an interior lip 5 that extends inside the vehicle on the bottom surface that is the outside of the wall that connects the vehicle outer side wall 3 and the vehicle inner side wall 6 of the seal body 2 is provided. In an opening seal 1 of an automobile formed by adhering an end 5a, the interior of the seal body 2 near the lower end corner portion which is the outer corner portion between the connecting wall and the vehicle inner side wall 6 and the interior. on at least one heat-softenable resin part 7a of the site of the lip 5, the provided 7b, is intended to fix a portion of the interior lip 5 near the lower end corner portion of the seal body 2 by heating and fusing with the mold ,
In the second configuration, a hollow seal portion 4 that elastically contacts the door when closed is provided on the outer side wall 3 of the seal body 2 having a U-shaped cross section sandwiched between the inner peripheral edges of the door opening, and the seal in exterior side wall 3 and the inner side wall 6 and a wall connecting the interior lip 5 extending inside the vehicle to become the bottom outer proximal 5a and to the extruded automobile comprising adhering the opening seal 1 of the main body 2, the seal and around the lower end corner portions become the connecting wall of the main body 2 and the corner outside between the interior side wall 6, the interior lip 5 parts and each heat softening of the resin piece 7a opposed thereto, 7b is The two resin parts 7a and 7b facing each other are pressure-bonded by heating and pressure when the opening seal 1 is attached with a mold, and the portion of the interior lip 5 is fixed near the lower end corner of the seal body 2 To do.
[0005]
【Example】
Hereinafter, a first embodiment of the present invention will be described in detail with reference to the drawings. In FIG. 1, reference numeral 1 denotes an opening seal, which is a hollow seal portion that elastically contacts a door when closed on a vehicle outer side wall 3 of a U-shaped seal body 2 sandwiched by a flange F indicated by a chain line at the inner peripheral edge of the door opening. 4, and a base end 5 a of an interior lip 5 that extends inward of the vehicle is attached to substantially the center of the bottom surface of the seal body 2.
[0007]
A resin portion 7a such as a heat-softening ABS resin is provided in the vicinity of the lower end corner portion of the vehicle interior side wall 6 of the seal body 2, and the resin portion 7b of the same material is provided near the base of the interior lip 5 facing the resin portion 7a. Is provided. The resin portions 7a and 7b may be provided integrally with the interior lip 5 at the time of extrusion molding.
When the opening seal 1 is attached by a mold or the like so that the opening seal 1 can be assembled to a corner portion having a small R of the vehicle body door opening, both resin portions 7a and 7b facing each other with heating and pressure of about 200 ° C. are mutually connected. Crimped. Accordingly, the vicinity of the base of the interior lip 5 is fixed near the lower end corner of the seal body 2. Further, as shown in FIG. 3, the resin portion 7b is provided only in the vicinity of the base of the interior lip 5, and the resin portion is not provided on the opposite side, and as shown in FIG. 7b may be provided.
[0008]
Therefore, as shown by a chain line in FIG. 2, the front end portion 5b extending to the vehicle interior side of the interior lip 5 of the opening seal 1 can be reliably brought into close contact with the end portion 8 of the interior material as shown by the chain line in FIG. The appearance can be improved by preventing the occurrence of skies between the two materials.
[0009]
【The invention's effect】
In the opening seal of the door opening of the present invention, an interior lip extending from the bottom surface of the seal body having a U-shaped cross section to the inside of the vehicle is fixed to the vicinity of the base near the lower end corner of the seal body via a heat-softening resin portion. As a result, the tip of the interior lip can be securely in close contact with the end of the interior material when attached to the corner of the vehicle body, and cost reduction can be expected compared to the case where the vicinity of the base of the conventional interior lip is molded. There are features.
