DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a weatherstrip for an automobile, for example, attached to a sash provided above a belt line of the automobile.

[0002]

2. Description of the Related Art As shown in FIGS. 3 and 4, for example, in a sash door vehicle, a subseal weather strip 2 (which seals a body panel B along a sash 1 provided above a belt line of the vehicle along the sash 1). In FIG. 3, the front side sub-seal weather strip is shown on the left side, and the rear side sub-seal weather strip is shown on the right side). The center pillar has the rear edge of the front door sash and the front side of the rear door sash. A pillar weatherstrip 3 for sealing the rim is attached. FIG. 9 shows a cross section taken along line CC of FIG. The sub seal weather strip 2 is attached to the vehicle outside of the main seal weather strip 5.

[0003] The sub-seal weather strip 2 is formed by connecting a molded part 2B to an end of an extruded part 2A. As shown in FIGS. 5 to 8, the molded portion 2 </ b> B is generally located outside the end of the sash 1 and is in contact with the end to prevent the sub-seal weather strip 2 from shifting and positioning. A part 4 is formed. 7 is a sectional view taken along line AA of FIG. 6, and FIG. 8 is a sectional view taken along line BB of FIG.

[0004]

When the subseal weather strip 2 is mounted on the sash 1, it is usual to insert the extruded portion 2A while sliding the extruded portion 2A into the groove M of the sash 1. As shown in FIG. 8, the molded part 2B having
Unlike the general extruded part 2A in which a gap is set, as shown in FIG. 7, the shape of the stopper part 4 is set large so that the stopper part 4 comes into contact with the end part of the sash 1. It was extremely difficult for the molded part 2B to slide and insert the sub-seal weather strip 2 connected to the terminal part into the sash 1. If an attempt is made to forcibly insert the molded part 2B, the molded part 2B may be broken.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a weather strip for an automobile which can be easily attached to a sash while slidingly inserting a weather strip having a molded terminal portion.

[0006]

To achieve the above object, a weatherstrip for a vehicle according to the present invention is attached to a groove (M) of a sash (1) having a substantially C-shaped cross section. At the end of the weatherstrip (2),
An automobile weather formed with a molded part (2B) having a stopper part (4) located outside the terminal part of the sash (1) and in contact with the terminal part to prevent displacement and position of the weather strip (2). A notch (10A, 10B) is formed on the rear side of the strip opposite to the end portion side from the position of the contact surface (4A) of the stopper portion (4), and the notch portion (10A) is formed. , 10B) with the fulcrum as the fulcrum, the side of the stopper (4), which is on the front side thereof, is freely bendable in the direction of the opening of the groove (M) of the sash (1), and the cutout is exposed to the front in the bent state. (10A, 10
B) is fitted into the sash (1) and is slid so that it can be attached to the groove (M).

According to a second aspect of the present invention, there is provided a weather strip for an automobile according to the first aspect, wherein the notch portions (10A, 10B) are provided in the molded portion (2B).

The symbols in parentheses described in the means for solving the above-mentioned problems correspond to the symbols described in the drawings and the embodiments of the invention described later.

According to the present invention, a notch is formed on the rear side of the position of the contact surface of the stopper for preventing slippage and positioning provided on the molding end of the weather strip,
The notch portion is used as a fulcrum, and the stopper portion, which is on the front side of the notch portion, can be bent toward the opening of the sash groove. Then, a notch portion exposed to the front side in a folded state is fitted into a sash, and is slid to be attached to the groove portion. In this way, the notch that fits into the sash is exposed,
The molded portion having the stopper portion abutting on the sash terminal portion can be easily inserted without any particular obstacle, and thereafter the mounting is completed only by sliding the weather strip in the groove of the sash.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment in which the automotive weather strip of the present invention is applied to a sub-seal weather strip will be described with reference to the drawings. The same parts as those in the conventional example are denoted by the same reference numerals. FIG. 1 is an enlarged perspective view showing a terminal portion of the sub seal weather strip according to the embodiment of the present invention.

The sub-sealing weather strip 2 according to the embodiment of the present invention comprises a mounting base 21 and a sealing lip 22 formed integrally with the mounting base 21 to elastically contact a body (not shown) to seal the inside and outside of the vehicle. It is attached to the groove M of the sash 1 having a substantially C-shaped cross section as shown in FIG. 2 provided above the belt line, and is formed by integrally connecting the extruded part 2A and the molded part 2B. . The sash 1 is formed in the molded part 2B in the same manner as in the conventional example (FIG. 4).
A stopper 4 is formed on the outer side of the end of the seal strip and in contact with the end to prevent displacement and position of the sub-seal weather strip 2.

The mounting base 11 formed on the molded part 2B has a cross-sectional shape of the mounting base 2 of the extruded part 2A continuously extending from the connection part T with the molded part 2B to the molded part 2B.
Abutment surface 4 where stopper portion 4 abuts on sash 1
Notch portions 10A and 10B are formed on the connection portion T side (rear side opposite to the terminal portion side which is the front side) from the position of A. Two notches 10A and 10B are formed symmetrically with respect to the portion of the molded portion 2B that is concave and is continuous from the seal lip portion 22 of the extruded portion 2A.

With the notches 10A and 10B serving as fulcrums, the sash 1
2 can be bent in the direction of the opening of the groove M, and as shown in FIG.
The sash 1 is slidably inserted into the sash 1 with 10B facing forward. That is,
Hook-shaped portions 1A, 1B of sash 1 forming a substantially C-shaped cross section
The notch portions 10A and 10B exposed when the stopper portion 4 side is bent upward are fitted into the groove portion M, and the mounting base portions 11 and 21 are inserted into the groove portion M by sliding.
Can be easily inserted. Thereafter, the sub-seal weather strip 2 is slid in the X direction until the stopper 4 comes to the end of the sash 1, and the stopper 4 is returned to the original substantially horizontal position (the state of FIG. 1) at the end. Installation is completed.

In this embodiment, the notch 10
A and 10B are provided on the mounting base 11 of the molded part 2B.
You may make it provide in the attachment base 21 of the extrusion molding part 2A. Also, an example in which the present invention is applied to a sub-seal weather strip has been described. However, the present invention is not limited to this. .

[0015]

As described above, according to the automotive weather strip of the present invention, the stopper portion is bent with the formed notch as a fulcrum, fitted into the sash from the exposed notch, and slid. The sash can be easily inserted into the sash, and during this time, the stopper can be smoothly mounted without obstructing the insertion. Therefore, the weather strip can be attached to the molded portion of the terminal portion without causing breakage.
