Abstract

(57) [Summary] [Purpose] To provide a weather strip corner structure having a small number of parts, a simple structure, and a good appearance. [Structure] A weather strip to be mounted along the peripheral edge of a door 2, and assuming that the weather strip is bent so that it can be mounted along the peripheral edge of a corner portion, the base of the lip 3c of the linear weather strip 3 of the extruded product is elongated. Direction from the end of the portion that hits the center pillar portion 1b side to the roof portion 1a
The slit S1 is inserted up to a point slightly beyond the door corner portion of the lip 3c, and the portion of the lip 3c that hits the door corner portion extends from the tip to the base, that is, toward the slit S1 and is perpendicular to the slit S1 and does not reach the slit S1. The slits S2 are inserted, and the mold forming members M1 and M2 are embedded in the open portions formed in the slits S1 and S2 in a state of being bent at a substantially right angle along the door corner portion with the slit S2 as a boundary.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an improvement in the structure of the portion to be attached to the door corner of the weather strip, which is attached to the peripheral edge of the door, and the hollow seal portion / lip is elastically attached to the opening edge of the body.

[0002]

[Prior Art]

 Conventionally, as a weather strip made of rubber or rubber-like elastic material that is attached to the peripheral edge of the door, a base part that is attached to the peripheral edge of the door via a retainer, a hollow seal part on the inside of the car that makes elastic contact with the opening edge of the body, and a lip on the outside of the car are integrated. Although the extruded product is used for the straight part, the corner part that is geometrically complicated is usually the molded product, so the roof part and the center pillar are generally used. It was configured by connecting multiple parts with different shapes, such as the central part, the center parting seal part, and the lower part of the door.

Therefore, the conventional one has a problem that the number of mold-molded portions is increased, the cost is increased accordingly, and the appearance is not good.

[0004]

[Problems to be solved by the device]

 The problem to be solved is that the conventional one has many mold forming parts, the cost is high, and the appearance is not good.

[0005]

[Means for Solving the Problems]

 The present invention is a weather strip that is manufactured by extruding a rubber or rubber-like elastic body to be installed along the peripheral edge of the door 2, and is assumed to be bent so that it can be installed along the peripheral edge of the corner. Slit the linear weatherstrip 3 of the extruded product from the end of the portion corresponding to the center pillar portion 1b to the point slightly beyond the door corner portion of the portion corresponding to the roof portion 1a in the longitudinal direction. S1 is inserted, and a slit S2 having a length perpendicular to the slit S1 and not reaching the slit S1 is inserted from the tip of the lip 3c toward the root, that is, the slit S1 at the portion corresponding to the door corner portion, and further the slit S2. Bent at a substantially right angle along the door corner with the boundary as a boundary, and the mold is formed on the open part formed in the slits S1 and S2. Those formed by arranging the form members M1, M2.

【Example】

 An embodiment will be described with reference to the drawings. 1 is an opening edge of an automobile body, 1a is a roof side portion thereof, 1b is a center pillar portion, 3 is a weather strip attached along a peripheral edge of a rear door 2, and one of corner portions is Except for the parts, it is manufactured by extruding rubber or rubber-like elastic material. The base part 3a is attached to the peripheral edge of the door 2 by the retainer clip R. A hollow seal portion 3b elastically contacting the contact surface and a lip 3c are integrally connected. Explaining the structure of the door corner portion, assuming that the door corner portion is bent so that it can be attached along the periphery of the corner portion, the base of the lip 3c of the linear weather strip 3 of the extruded product is longitudinally aligned with the center pillar. A slit S1 is inserted from the end of the portion corresponding to the portion 1b to a point slightly beyond the portion corresponding to the door corner portion of the portion corresponding to the roof portion 1a. A slit S2 having a length perpendicular to the slit S1 and not reaching the slit S1 is provided. Further, the weather strip 3 is bent at a substantially right angle along the door corner portion with the slit S2 as a boundary, and the molding members M1 and M2 are embedded in the open portions formed in the slits S1 and S2. The base portion 3a of the weather strip 3 on the side of the center pillar is attached by a retainer R, the divided lip 3c is fixed to the door 2 with a double-sided adhesive tape or clip, and the end is attached to the lower portion of the door 2 as shown in the figure. Not connected to the center pillar part. In the figure, 4 is a front door, 5 is an inside of the vehicle, and 6 is an outside of the vehicle.

To explain the operation, the weather strip 3 having the above-mentioned configuration has a reduced number of parts because it is obtained by bending one extruded product and filling the molding members M1 and M2 in the opening. , The structure is simple and clean.

[0008]

[Effect of the device]

 Since the present invention is configured as described above, a total of 4 cross sections including the roof cross section, the center pillar cross section, the center parting seal surface, and the door lower section cross section can be made in one cross section, and the appearance is also small in the molding part. It's done and looks good.
