BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a glass run mounted on a door frame of an automobile.

[0002]

2. Description of the Related Art A glass run is mounted along the inside of a door frame 2 of an automobile door 1 as shown in FIG. 3, and when the door glass 3 is raised and closed, the door glass 3 is closed. The space between the outer periphery and the door frame 2 is sealed.

[0003] As shown in FIG. 4, to the body of the roof side
The glass run 4 attached to the door frame 2 is provided with a trim portion 41 having a U-shaped cross section and attached to the flange 21 of the door frame 2 and a hollow seal portion 42 against which an upper edge of the door glass 3 is pressed. 3-5331
No. 4).

[0004] In the seal portion 42 is a hollow body closed lower end opening of the base portion 43 of the solid rubber of the U-shaped cross section that opens downward in the sponge rubber seal wall 46, than the trim portion 41
Exterior side is located in the upper end corner portion of the interior side of the base portion 43, a series to be connected by the connecting portion 48 and the exterior of the upper end of the trim portion 41 made of solid rubber, sidewall of the exterior base 43 44 Is locked to the lower edge 22 of the door frame 2 on the outside of the vehicle.

When the door glass 3 is lifted up and closed, the upper edge of the door glass 3 is
6 and the side wall 44 of the base 43 on the vehicle exterior side
The lower end of the side wall 45 on the inside of the vehicle moves so as to sandwich the door glass 3 from both sides.

[0006]

When the door glass 3 rises, the upper end of the door glass 3 is gradually inclined toward the inside of the vehicle. Then, the upper edge of the door glass 3 comes into contact with the seal wall 46, and then pushes up the seal wall 46 so as to fall down to the inside of the vehicle to reach the rising end.

Accordingly, when the door glass 3 is relatively displaced toward the inside of the vehicle due to a variation in the construction of the door frame 2 and the door glass 3, when the seal wall 46 is pushed up by the door glass 3 as shown in FIG. The lower part of the side wall 45 on the inside of the vehicle may fall down inside the vehicle. When this collapse occurs, the sealing property becomes unstable, and the gap between the lower end of the side wall 44 on the outside of the vehicle and the door glass 3 is greatly opened, and the appearance around the door is deteriorated.

The present invention provides a glass run in which a stable sealing force can be obtained and a gap does not occur between the door glass and the side wall on the outside of the vehicle even if the position of the door glass varies. The task was to do.

[0009]

Means for Solving the Problems A trim section 51 and its vehicle
Seal the outer opening at the lower end of the base with a U-shaped cross section.
Glass run with hollow seal closed by
As illustrated in FIG. 1, the seal portion 52 and the trim portion 5
1 and the lower end of the inner side wall 55 of the seal portion 52
Connecting part of the solid rubber that connects the
It is characterized by being connected at 58 .

[0010]

When the door glass 3 is closed, the sealing portion 52 is closed.
Even if the side wall 55 on the vehicle interior side of the base 53 is pushed in the vehicle inward direction, the side wall 55 is supported by the connecting portion 58 and does not fall down.
When the sealing wall 56 is pushed up by the door glass 3, only the side wall 54 on the outside of the base 53 follows and is drawn into the inside of the vehicle, so that a large gap is formed between the lower end of the side wall 54 and the door glass 3. Does not occur.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In the embodiment shown in FIG.
Has a trim portion 51 and a seal portion 52. The trim portion 51 has a U-shaped cross section and has an insert 6 embedded therein. From the lower end of the trim portion 51, an inner seal lip 57 extends obliquely upward in the direction toward the outside of the vehicle.

An opening end of the seal portion 52 has a U-shaped cross section whose opening direction is opposite to that of the trim portion 51 and is closed by a seal wall 56 to form a hollow body having a substantially square cross section. A lip 540 that extends below the seal wall 56 is formed at the lower end of the outer side wall 54 of the base 53.

The seal portion 52 is entirely formed of the door frame 2.
Outside the trim part 51 attached to the flange 21
And the sealing wall 56 faces the upper edge of the door glass 3
ing. The seal portion 52 is connected by a connecting portion 58 that connects the lower end of the inner side wall 55 of the base portion 53 and the upper end of the trim portion 51 located on the inner side of the vehicle to the inside and outside of the vehicle . The glass run 5A is an extruded body, the seal wall 56 and the inner seal lip 57 are made of sponge rubber, and the other parts are made of solid rubber.

In the glass run 5A, the trim portion 51 is attached to the flange 21 of the door frame 2 so as to wrap the same.
The upper part of the outer side surface of the seal part 52 is attached to the door frame 2.
Is fitted to the door frame 2 by being fitted inside the lower edge 22 on the outside of the vehicle.

In the glass run 5A configured as described above, when the glass run 5A and the door glass 3 are in a normal positional relationship, when the door glass is closed, the seal wall 56 is positioned substantially at the center in the width direction thereof. The upper edge of the door glass 3 is sealed at a position near the inner side wall 55 of the seal portion 52 when the door glass 3 is moved toward the inside of the vehicle relative to the glass run 5A. Wall 56
While applying a pressing force to the side wall 55 toward the inside of the vehicle.

However, since the lower end of the side wall 55 is supported by the solid rubber connecting portion 58, the entire lower portion of the seal portion 52 is not inclined toward the vehicle interior. Also, only the side wall 54 on the outside of the vehicle tilts toward the inside of the vehicle due to the pulling force generated by pushing up the seal wall 56, and the tip of the lip 540 approaches the outside of the door glass 3. Is an almost continuous surface with no mouth-opening that would impair the appearance.

FIG. 2 shows another embodiment of the present invention.
On the glass run 5B, a projection 59 is formed at the upper outer end of the base 53 of the seal portion 52 to extend the outer surface of the vehicle side wall 54 upward.
At the lower edge 22 on the outside of the vehicle. Other structures are the same as those of the glass run 5A of the previous embodiment, and the corresponding parts are denoted by the same reference numerals.

The glass run 5B of this embodiment has the following advantages in addition to the same operation and effect as the glass run 5A. That is, when the lower end edge 22 on the outer side of the vehicle is shifted toward the inner side of the vehicle due to a variation in the molding of the door frame 2, the locking position by the lower end edge 22 is set above the base 53. The base 53 can be easily and easily fitted into the lower edge 22.

[0019]

As described above, in the glass run according to the present invention, even if the door glass is positioned inside the vehicle, the entire lower portion of the sealing portion is inclined by pushing up the door glass to lower the sealing performance. In addition, there is no gap between the lower end of the side wall on the vehicle outside of the seal portion and the outer surface of the door glass.
