DETAILED DESCRIPTION OF THE INVENTION

[0001]

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 structure of a front end portion of a weather strip mounted along a roof side of a vehicle body .

[0002]

BACKGROUND OF THE INVENTION frameless door model, as shown in FIG. 1, the roof side 3 extending from the front pillar 1 in quarter pillar 2, the weather strip 5 is attached to a series of back and forth when the door is closed the door glass 40 It is designed to seal around. The weather strip 5 is a tubular hollow body of sponge rubber, and has front and rear ends connected to molded end portions 5A and 5B having closed ends.

On the other hand, a generally triangular door mirror bracket 6 is attached to the front end of the door panel of the front door 4, so that the front edge of the door mirror bracket 6 is pressed against the front end 5A.

FIG. 3 shows a front molded terminal portion 5A on which the door mirror bracket 6 is pressed. The terminal portion 5A has substantially the same cross-sectional shape as a general portion along the roof side, and has a hollow shape. A garnish 7 having an inner seal lip 52 branching into a T-shaped cross section at the inner end of the main body portion 51, and a tip of a first lip 52a extending inward is attached to the roof side along the inside of the weather strip.
Are engaged. When the door is closed, the inner surface of the door mirror bracket 6 is pressed against the second lip 52b extending outward.

[0005]

By the way, the second lip 52b of the inner seal lip 52 is pressed on the inner peripheral surface of the door glass 40 in the general portion of the weather strip, but is not pressed in the terminal portion 5A. The inner seal lip 52 is garnished to the inner seal lip 52 because it is pushed by the thick door mirror bracket 6 that protrudes inward from the inner surface of the garnish.
In some cases, the tip of the first lip 52a may move in the direction of arrow B and come off the garnish 7. And this place is easily seen by the occupants, so the appearance is impaired.

As a countermeasure, it is conceivable to increase the rigidity of the base of the first lip 52a by increasing the thickness so as to fill the hollow portion 521 inside the first lip 52a to prevent the first lip 52a from falling down. . However, at the root part which is partially thicker than other parts, the surface is roughened by the foaming gas during the molding, and the appearance is not good.

The present invention has been made in view of the above circumstances, and has an object to provide a weather strip having a good appearance without falling down of an inner seal lip in contact with a garnish.

[0008]

SUMMARY OF THE INVENTION The present invention is a sponge rubber weatherstrip that is mounted along the roof side of an automobile body , as shown in FIGS.
Terminal parts 5A and 5B on the front and rear sides are molded
Formed on the side surface of the main body 51 to have a T-shaped cross section.
Having an inner seal lip 52 that extends,
The tip of the first lip 52a extending inside the lulip 52
Is attached to the roof side along the inside of the weather strip
The second lip that engages with the girder garnish 7 and extends outward.
When the door 52b is closed, the front end of the molding terminal
In 5A, it is pressed by the inner surface of the door mirror bracket 6.
Of the front side mold in the weather strip 5
In the molded terminal portion 5A, the root portion of the first lip 52a
On either the inner surface or the side of the body 51 facing it,
Rib-shaped projections 5 projecting toward and abutting against the other side
Form 3

[0009]

When the door is closed and the second lip 52b is pushed by the door mirror bracket 6, the first lip 52a is pressed.
Is about to fall, but is supported by the projection 53 to prevent falling.

[0010]

1 and 2, a sponge rubber end-molded end portion 5A is connected to a front end of a weather strip 5 of a sponge rubber extruded body attached along a roof side 3 of a vehicle body. I have. Molding terminal 5A
Has the same basic structure as the general part of the extrusion molding.
A hollow body 51 (A), the car body 51
An inner seal lip 52 extending in a T-shaped cross section from one end of the inner side surface is provided. The retainer 10 is fixed to the roof side including the front pillar 1 by the base 510.
It is locked to.

On the other hand, a door mirror bracket 6 is attached to the front end of the door panel of the front door 4 so that the front edge of the door glass 40 moves up and down in the bracket 6 when the door glass 40 moves up and down. A garnish 7 is attached to the roof side 3 along the inside of the weather strip 5. And this garnish 7
The front end of the first lip 52a extending to the inside of the inner seal lip 52 is engaged.

The first lip 5 of the inner seal lip 52
The root portion 521 of 2a is lightened. And
In the front molding terminal 5A, the side of the body 51
Projecting toward the first lip 52a over the entire length of the molded terminal portion 5A on a surface facing the inner surface of the first lip 52a.
A rib-shaped projection 53 is formed, and the height of the projection 53 is set to a height almost in contact with the inner surface of the base of the first lip 52a opposed thereto. The protrusion 53 is formed on the inner surface of the root of the first lip 52a as shown in FIG.
You may make it contact the side surface of the main body 51 facing this.

The weather strip 5 constructed as described above
When the front door 4 is closed, the peripheral edge of the door glass 40 and the front edge of the door mirror bracket 6 are pressed against the main body 51 of the weather strip 5. At the same time, the inner surface of the peripheral edge of the door glass 2 and the inner surface of the front edge of the door mirror bracket 6 are pressed against the tip of the second lip 52 b of the inner seal lip 52.

At this time, in the molding terminal portion 5A, the door
Door mirror bracket protruding from the inner surface of lath 40
6, the second lip 52b receives a stronger pressing force than the extruded general portion of the weather strip, so that the first lip 52a is subjected to a force for pushing it down.
The force is received by the projection 53 whose tip is in contact with the side surface of the main body 51 , and the first lip 52a does not fall down and therefore does not come off the garnish 7.

[0015]

As described above, according to the present invention, at the front portion of the front door opening, the inner seal lip of the weather strip which engages with the garnish around the opening can fall down even if it is pushed in by the door mirror bracket when the door is closed. Does not occur and therefore does not disengage from the garnish.
