PURPOSE:To improve productivity and attaching performance of a weather strip to be attached on the outer periphery of the sunshine roof panel of an automobile. CONSTITUTION:In a weather strip 3 provided with a base part 31 and a seal part 32, and to be attached on the outer periphery of a sunshine roof panel 2, a cut 37 whose depth is increased toward the corner center part from both sides is provided on the base part 31 facing to corner parts on the four counters of the sunshine roof panel 2, and the center of the cut 37 is positioned and attached to the corner center part of the sunshine roof panel 2.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a weather strip for automobiles, and more particularly to a weather strip mounted on the outer periphery of a sunroof panel.

[0002]

2. Description of the Related Art As shown in FIG. 1 (A), an opening 10 formed in a roof 1 of an automobile is provided with a sunroof panel 2 made of glass or transparent resin capable of opening and closing the opening, and the outer periphery of the sunroof panel 2. The strip 3 is attached.

As shown in FIG. 2, the weather strip 3 generally has a base portion 31 that holds the outer periphery of the sunroof panel 2 with a groove 33 and a hollow seal portion 32 that is pressed against the opening edge of the roof opening 10. It has a structure. Further, a frame member 4 is attached to the inner surface of the outer periphery of the sunroof panel 2,
While being bonded with the sunroof panel 2 and the adhesive 5,
The outer edge flange is inserted into the groove 34 of the weather strip base 31.

The weather strip 3 is extruded, has its both ends connected to form a ring, and is fitted in series on the outer periphery of the sunroof panel 2.

[0005]

However, when the weather strip 3 is extruded as it is, the thick base portion 32 made of solid rubber is difficult to bend along the four corners of the sunroof panel 2. Therefore, as shown in FIG. 3, a notch 35 is provided at a corner-corresponding portion of the base 31, the corner is bent, and the notch 35 is replenished by molding. 36 is a mold replenishing section.

However, it is troublesome to set the bent weather strip 3 in the mold and mold it, and the weather strip 3 is displaced when the set and the mold is closed.
It is easy to get caught at the protruding part of the product, resulting in a product defect.

Therefore, the present invention has been made to provide a weather strip that can be mounted on the outer periphery of a sunroof panel with good workability without molding.

[0008]

According to the present invention, as shown in FIG. 1, in a weather strip for a sunroof panel having a base portion 31 and a seal portion 32, a base portion 31 of a portion corresponding to a corner portion of the sunroof panel 2 is provided. In addition, a notch 37 that gradually becomes deeper from both sides toward the center of the corner is formed.

[0009]

The weather strip 3 can be easily bent by providing the notch 37. Further, since the bend is centered on the center of the corner, when the weather strip 3 is fitted on the outer periphery of the sunroof panel 2, the alignment can be easily and accurately performed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In the embodiment shown in FIG. 1, a weather strip 3 mounted on the outer periphery of a sunroof panel 2 made of glass plate.
Is a rubber extruded product, and has a groove 33 fitted on the outer periphery of the sunroof panel 2 and a groove 34 for inserting the end edge of the frame member 4 (FIG. 2).
The base portion 31 is made of solid rubber and has a hollow sponge rubber seal portion 32.

The weather strip 3 is cut into a predetermined length and joined at both ends to form a ring. The length is such that when it is fitted onto the outer periphery of the sunroof panel 2, some tension is generated in the length direction.

Prior to the above joining, the sunroof panel 2
Notches 37 are provided in the thick portions of the base portion 31 forming the grooves 33 at positions corresponding to the four corners of the. Cutout 37
Is a shape that gradually becomes deeper from both sides of the bending center (corner center) for bending the weather strip 3 toward the center.

The weather strip 3 is attached to the sunroof panel 2
The ring-shaped weather strip 3 is attached to the outer circumference of the
The groove 33 to the sunroof panel 2
Fit on the outer periphery of. In this case, since the weather strip 3 bends at the deepest center of the notch 37, the sunroof panel 2
It can be easily and accurately aligned with the corner portion of. At the corner portion, the bottom of the groove 33 is in close contact with the corner peripheral edge of the sunroof panel 2 due to the tension acting on the weather strip 3.

[0014]

According to the present invention, the weather strip can be easily attached to the outer periphery of the sunroof panel without misalignment only by providing a notch in a portion of the weatherstrip corresponding to the corner portion of the sunroof panel. Can be installed. Molding at the corner is unnecessary, which is advantageous in productivity and cost.
