Abstract

(57) [Abstract] [Purpose] To provide a weatherstrip opening trim with good appearance and good sealing property at the door corner. A U-shaped opening trim 10 for a weather strip of an automobile is provided with a hollow lip 13 having a rhombic cross section projecting from a hollow seal portion 15 side of an opening end thereof. This opening trim 10 is deformed vertically at the location where the diamond-shaped hollow lip 13 is bent at the door corner, and the width D of the lip 13 becomes smaller,
It does not ride on the root of the body flange 30, and its width D is the same as that of the straight part, improving the appearance, and the tip of the elongated rhombic hollow lip 13 press-bonds to the surface of the body flange 30. The property is improved.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a weather strip opening trim for an automobile, and more particularly to an improvement of a lip projecting from the opening end of the trim.

[0002]

[Prior Art]

 Conventionally, hook-shaped lips 11, 12 called a round neck type shown in FIG. 2 and a sickle neck type shown in FIG. 6, for example, are provided on the hollow seal portion side of the opening end of a weather strip opening trim 10 of an automobile. The former is a little difficult to bend, and the latter is a little easy to bend.

Due to the difficulty of bending the bending portion as described above, in the former round neck type, as shown in FIGS. 3 to 5, in the door corner portion, the lip 11 is wound on the base side and the body flange It is said that the lip 11 will have a large width (between the hollow seal portion and the tip of the lip) D because the sealing property will be impaired and the sinking will be difficult when bent. There is a problem. On the other hand, in the latter sickle neck type, since the lip 12 sinks when bent as shown in FIG. There is a problem to say.

[0004]

[Problems to be solved by the device]

 The problem to be solved is that in the above-mentioned conventional case, the sealability of the lip is impaired, the appearance is deteriorated, or a gap E is generated between the lip and the body flange 30, and the dipping water W enters. It is to be.

[0005]

[Means for Solving the Problems]

 Description will be made with reference to FIGS. 8 to 11. The present invention is a U-shaped opening trim 10 for a weather strip of an automobile, in which a hollow lip 13 having a rhombic cross section is projected from a hollow seal portion 15 side of an opening end thereof.

[0006]

【Example】

 An example will be described. 10 is a U-shaped opening trim of a weather strip of an automobile, 13 is a hollow lip having a rhombic cross-section projecting toward the hollow seal portion 15 side at the opening end, and 20 is a core embedded in the opening trim. Gold, 30 is a body flange into which an opening trim is fitted. Reference numeral 14 denotes a plurality of claws protruding from the inner surface of the opening trim, and when the opening trim is fitted, the body flange 30 is elastically contacted with the body flange 30 to be clamped.

The operation will be described. At the door corner, as shown in FIGS. 10 and 11, when the diamond-shaped hollow lip 13 is bent, the diamond-shaped hollow lip 13 is crushed and deformed vertically, and the width of the lip 13 becomes smaller. The width does not differ from the straight part of the hollow lip 13 and the appearance is improved, and the tip of the rhombus hollow lip 13 that is further crushed and becomes vertically long is not attached to the root of the flange 30. Since it is crimped to the surface of the flange 30, the sealing property is improved, and the ingress of water through the water is prevented.

[0008]

[Effect of the device]

 Since the present invention is configured as described above, at the door corner, the diamond-shaped hollow lip 13 is bent and deformed to be vertically long, the width of the lip 13 becomes small, and it does not ride on the root of the body flange 30 and its width. Has no difference from the straight portion of the hollow lip 13 to improve the external appearance, and the longitudinal end of the diamond-shaped hollow lip 13 is pressed against the surface of the body flange 30 to improve the sealing performance.
