BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a weather strip for an automobile, and more particularly to a weather strip mounted along a front pillar of a sashless door car.

[0002]

2. Description of the Related Art As shown in FIG. 4, in a sashless door car, a weather strip 6 for sealing the outer periphery of a door glass 4 is attached along a roof side including a front pillar 1 and a center pillar 2. Kaisho 64-
No. 32214). FIG. 5 shows a cross section of a portion of the weather strip 6 along the front pillar 1. The weather strip 6 forms a hollow body with a mounting base 61, outer and inner side walls 62 and 63, and a sealing wall 64. When the door glass 4 is closed, the front edge of the door glass 4 is pressed against the seal wall 64 and is wrapped by the seal wall 64.

On the other hand, a door 3 is provided with a door mirror 5. Conventionally, the door mirror 5 is generally mounted on a triangular mirror bracket provided at the front end of the belt line 30 of the door 3. However, due to demands such as the strength of mounting the door mirror 5 and improving the visibility of the door glass 4, FIG. Thus, it is considered that the door mirror 5 is directly attached to the side surface of the main body of the door 3. With such a door mirror mounting structure, the front edge of the door glass 4 is sealed from the upper portion to the belt line 30 by the weather strip 6 mounted on the front pillar 1.

However, in this case, the following problem occurs. That is, the outer surface of the front pillar 1 and the outer surface of the door glass 4 are set as small as possible in the step 1 (FIGS. 5 and 6) in accordance with the demand for the leveling of the side surfaces of the vehicle, but are shown in FIG. As described above, the outer plate 31 of the main body of the door 3 bulges outward beyond the door glass entrance 32, and the outer surface of the front pillar 1 is made to be continuous with the outer surface of the outer plate 31. The edge deviates relatively toward the inside of the vehicle with respect to the front pillar 1 as it approaches the belt line 30. Therefore, the front edge of the door glass 4 is the front pillar 1
Also, the weather strip 6 attached along the vehicle is relatively displaced toward the inside of the vehicle as it approaches the belt line 30, and assumes a position indicated by a broken line in FIG. Therefore, the sealing wall 6
4 was not sufficiently wrapped, especially from the outside of the vehicle, and there was a possibility that the sealability and appearance would be reduced.

[0005]

SUMMARY OF THE INVENTION In view of the above circumstances, the present invention is directed to an automobile having a sashless door in which the front edge of the door glass is deviated toward the inside of the vehicle as the front edge of the door glass approaches the door belt line with respect to the front pillar. It is an object of the present invention to secure good sealing performance and appearance from the upper portion to the belt line position in a weather strip attached to a front pillar.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIG. 1, a weather strip 6 for sealing around a door glass is formed by extruded weather strips 6A and 6B, and a molded part 6C for connecting these parts to form a corner part. It comprises a molded part 6D connected to the lower end of the weather strip 6A and a molded part 6E connected to the lower end of the weather strip 6B. The weather strip 6A is attached to the roof side of the vehicle body including the front pillar 1 (FIG. 4). Molded part 6D is belt line 3
It is connected to the weather strip 6A at an intermediate position of the front pillar 1 above 0.

The upper part of the molded part 6D is a weather strip 6
A has a cross-sectional shape substantially the same as the cross-sectional shape of FIG. A (FIG. 5), and as shown in FIG. 2A, the mounting base 61 and the outer and inner side walls 62 extending away from both sides thereof. , and 63 to form a substantially fan-shaped hollow body with a seal wall 64 connecting the front end of this like side walls 62 and 63.
The seal wall 64 has a bulged shape on the vehicle interior in the width direction and a flat portion on the vehicle exterior, and a step 64a at a boundary slightly outside the vehicle rather than hollow. The sealing wall 64 and the side wall 62 on the outer side of the vehicle have a substantially uniform thickness, and have such a thickness that the sealing wall 64 can bend when pressed against the front edge of the door glass.

As shown in FIG. 3 (A), the molding base 6D has a mounting base 61 and a side wall 63 on the inside of the vehicle which have a cross section substantially the same as that of the upper part at a portion immediately above the belt line 30, as shown in FIG. In the portion 64, the stepped portion 64a is located closer to the side wall 63 on the inner side of the vehicle than in the upper portion. The side wall 62 on the outside of the vehicle is gradually reduced in thickness from the root side to the intermediate portion 62a. A portion extending from the intermediate portion 62a to the connection portion with the seal wall 64 at the tip is a thick portion 621 having a gradually increasing thickness, and when the seal wall 64 is pushed in at the front edge of the door glass, the intermediate portion is formed. The part 62a is bent
As a result, the thick portion 621 falls down toward the door glass without bending.

The position of the stepped portion 64a of the seal wall 64 is shifted toward the inside of the vehicle from the upper portion of the molded portion 6D to the lower side as it approaches the belt line 30. Bending of the outer side wall 62
The curved portion 62a is weathered downward from the upper portion of the molded portion 6D.
To the seal wall 64 in the longitudinal direction of the trip and downward.
A straight line gradually moving away from the tip of the side wall 62 to be connected
Is growing.

The weather strip 6 constructed as described above
When the door glass 4 is lifted up and closed, the front edge thereof is pressed against the extruded weather strip 6A and the sealing wall 64 of the molded portion 6D. In this case, the front edge of the door glass 4 is formed by the weather strip 6A and the molding 6
As it goes downward with respect to D, it shifts relatively toward the inside of the car,
In the molded part 6D close to the belt line, the lower part is considerably deviated to the vehicle inner side from the upper part. However, in the molded part 6D, the step 64a of the seal wall 64 is sequentially deflected toward the vehicle interior, so that the front edge of the door glass 4 is pressed against the step 64a of the seal wall 64 over the entire length.

FIG. 2B shows a state in which the front edge of the door glass 4 is pressed on the upper part of the molded portion 6 D. When the front edge of the door glass 4 is pushed into the step 64 a of the seal wall 64, Along with this, the front end side of the side wall 62 on the outside of the vehicle is slightly bent, and wraps around the outside of the vehicle at the front edge of the door glass 4, and good sealing properties are obtained.

[0013] FIG. 3 (B) shows a pressing state in the lower part of the molded part 6D, door glass 4 1 than the top ₁
Although it is displaced by -1 (1 ₁ > 1), the step 64a of the seal wall 64 is also displaced in accordance with this, so that the front edge of the door glass 4 pushes the step 64a. Along with this, the side wall 62 on the outside of the vehicle is bent at the bent portion 62a to form the thick portion 6
21 falls, but the width of the thick portion 621 gradually decreases downward.
Because it is wide, the front edge of the door glass 4 is gradually lowered.
Even if it is displaced toward the inside of the vehicle, the tip of the thick portion 621 is pressed against the outer surface of the front edge of the door glass 4, and the front edge is wrapped, so that good sealing properties are obtained.

[0014]

According to the present invention, when the door glass is closed, the front edge of the door glass comes into contact with the weather strip attached to the front pillar at an appropriate position over the entire length from the upper portion to the belt line. The wrapping around the front edge of the door glass is also good, improving the appearance and sealing along the front pillars.
