Abstract

(57) [Summary] [Purpose] To provide a weather strip with good sealing properties, low cost, and good appearance. A weather strip (30) comprising a base portion (31) fitted into a retainer (20) for sealing between an opening edge of a vehicle body and a door glass (10) and a hollow portion (32) elastically contacting with the door glass (10). In the portion 32, a reinforcing rib 40 is provided on the inner surface of the base portion 31 so as to project.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a weather strip that seals between a vehicle body opening edge and a door glass.

[0002]

[Prior art]

 Description will be made with reference to FIGS. 1 to 5. In the figure, one of the median lines drawn from the apex angle of the isosceles triangle is used as a symbol, and the symbol indicates the mold forming part Q on the filled side and the extrusion forming part P on the non-filled side. Is represented. Conventionally, in order to supplement the sealing property of the roof weather strip 30 that seals between the vehicle body opening edge and the door glass 10, a pad 50 is inserted into the hollow portion 31 as shown in FIG. As shown in FIG. 4, a rib 60 (the length of the rib 60 may be long as shown by a phantom line in FIG. 3) may be provided on the back side of the sealing surface, or a bridge 65 may be provided on the back side of the sealing surface as shown in FIG. Alternatively, as shown in FIG. 5, the seal back surface portion 35 is reinforced by thickening it. In addition, 31 is a base and 20 is a retainer. However, because of the above-described configuration, the one shown in FIG. 2 has a cost increase for inserting the pad 50, the outer appearance is deteriorated due to the surface being rough or broken during molding, and the one shown in FIGS. 3 and 4 has a door. There is a problem that the reaction force of the weather strip 30 is applied to the glass 10 quickly, the door glass 10 is pushed out of the vehicle, and the thing of FIG.

Further, in order to secure the sealing force, it is necessary to make the thickness of the sealing surface thicker than that of the extruded portion, and if it is attempted to seal it with the door glass 10, the sealing surface will be broken or wrinkled. There is also a problem called.

[0004]

[Problems to be solved by the device]

 The problems to be solved are that the above conventional roof weatherstrip increases the cost of pad insertion, deteriorates the appearance due to surface roughening or tearing during molding, pushes the door glass 10 out of the vehicle, and breaks the sealing surface. For example, wrinkles are generated.

[0005]

[Means for Solving the Problems]

 This will be described with reference to FIGS. 1 and 6 to 9. The first invention is that, in the molding portion of the weather strip 30 for an automobile, it comprises a base portion 31 fitted to the retainer 20 and a hollow portion 32 elastically contacting the door glass 10, and in the hollow portion 32, the base portion 31 is formed. Reinforcing ribs 40, 42 are provided on the inner surface so as to project.

In addition to the structure of the first invention, the second invention further comprises second reinforcing ribs 41, 43 projecting from the seal back surface 35 supported by the retainer 20 in the hollow portion 32. It is a thing.

[0007]

【Example】

 An embodiment will be described. Reference numeral 10 is a door glass, 30 is a weather strip that seals between the vehicle body opening edge and the door glass 10, and a base portion 31 fitted to the retainer 20 and the door glass 10 are provided. According to the first invention, the sealing surface of the hollow portion 32 is thin as shown in FIGS. 6 and 7, and the reinforcing ribs 40 are formed on the inner surface of the base portion 31 in the hollow portion 32. 42 is projected. In the second device, in addition to the reinforcing ribs 40 and 42 of the structure of the first device as shown in FIGS. 8 and 9, in the hollow portion 32, a second member is provided on the seal back surface portion 35 supported by the retainer 20. Reinforcing ribs 41 and 43 are provided so as to project. The reinforcing ribs 40 and 41 in FIGS. 6 and 8 may be rounded as shown in FIGS. 7 and 9 and deformed into the reinforcing ribs 42 and 43 in consideration of workability.

The operation will be described. Since the sealing surface is thin and the reinforcing ribs 40, 41, 42, 43 are provided, the sealing performance is improved, the cost is reduced, and the surface is roughened or broken when the sponge is formed. Etc. are prevented and the appearance is improved. Further, as in the conventional weather strip, the reaction force of the weather strip 30 is applied to the door glass 10 early, so that the door glass 10 is pushed out of the vehicle or is elastically contacted with the door glass 10 to be broken or wrinkled. Nor.

[0009]

[Effect of device]

 Since the present invention is configured as described above, the sealing property is improved, the cost is reduced, and the appearance is improved.
