DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevated door glass combined with a cut line seal for sealing between an opening edge of an automobile body and a door sash, and a glass run for sealing between the door sashes.

[0002]

2. Description of the Related Art A description will be given with reference to FIGS.
Conventionally, in combination with a cut line seal that seals between the body opening edge 10 and the door sash 20, the raised door glass 30 and a lower flange 26 that protrudes downward from the door sash 20 as a glass run that seals between the door sash 20 are provided. A hollow portion 42 having a U-shaped trim 41 to be fitted therein and connected to the upper end of the U-shaped trim 41 on the outer side P of the vehicle
The upper end of the glass run 40 having an abutment is brought into contact with the lower surface of the cut line seal 50 fitted to the upper flange 25 projecting outward from the door sash 20, and the vehicle exterior exposed surface Y of the hollow portion 42 is exposed to the cut line seal 50. The one substantially flush with the surface Z is used.

However, the conventional glass run 40
When the vehicle is running at high speed, the door glass 30 is sucked to the outside P of the vehicle, or there is a variation in the construction, and as shown in FIG. 3 , the glass run 40 is pulled to the outside P and falls off. In addition, there is a problem that the sealing performance is deteriorated, water is generated, and the appearance is deteriorated, and the wind noise is increased.

[0004]

The problem to be solved is that, in the above-mentioned conventional glass run, the glass run is pulled to the outside of the vehicle, falls off, deteriorates the sealing performance, generates underwater, etc., and deteriorates the appearance. To increase the wind noise.

[0005]

A description will be given with reference to FIGS. 1 and 4 to 6. An automotive glass run according to the present invention includes a lower flange 2 protruding downward from a door sash 20.
The upper end of the glass run 40 having the U-shaped trim 41 embedded with the metal core S to be fitted to the inner metal 6 and having the hollow portion 42 connected to the upper end of the U-shaped trim 41 on the vehicle outer side P is attached to the door sash 20. It is fitted to the upper flange 25 projecting outward and is brought into contact with the lower surface of the cut line seal 50 in which the core metal T is buried. Ri glass run 40 der formed by one, on the upper surface of the hollow portion 42, locks hanging on the cut line seal 50, is provided with a hooking portion 45 for preventing the movement of the vehicle exterior side P.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment will be described in detail. 10 is a body opening edge, 20 is a door sash, 30 is a door glass fitted to the door sash 20 so as to be able to move up and down, 40 is a glass run, and receives the raised door glass 30 Then, the space between the lower surface of the door sash 20 and the door glass 30 is sealed. The glass run 40 is a U-shaped trim 4 having a core S embedded therein , which is fitted to a lower flange 26 protruding downward from the door sash 20.
1 and a hollow portion 42 and a seal lip 43 having a substantially rectangular cross section which are respectively connected to the upper end and the lower end of the U-shaped trim 41 on the outer side P of the vehicle. The upper end of the hollow portion 42 is
The lower surface of the cut line seal 50 having a U-shaped cross section fitted on the upper flange 25 is brought into contact with the lower surface of the vehicle, and the exposed surface Y on the outside of the vehicle is
Exposed surface Z of the outside of the cut line seal 50 in which T is embedded
And almost the same. Further, the cut line seal 5
A hook 45 is provided on the upper surface of the hollow portion 42 at the end of the inner side Q on the upper surface of the hollow portion 42 to prevent movement to the outer side P.

As shown in FIGS. 4 and 5, the hooking portion 45 is provided with a protrusion 55 on the lower surface of the cut line seal 50 for preventing the hollow portion 42 from moving to the outside P of the vehicle. Instead, as shown in FIG. 6, two embodiments are presented in which the hook 45 is hung on the end of the cut line seal 50 on the inner side Q of the vehicle, but this embodiment is in line with the gist of the present invention. If there is, it is not limited to this.
S and T are core metals.

The operation will be described below.
In the state where the cut line seal 50 is attached, the engaging portion 45 is connected to the projection 55 of the cut line seal 50 or the inside Q of the vehicle.
And the movement of the door glass 30 to the outside P is prevented, so that the door glass 30 may be sucked out during the high-speed running of the car, or there may be a variation in the building,
It is not said that the glass run 40 is pulled out of the vehicle and falls off. Therefore, the sealing performance is improved, and the appearance of the glass run 40 is improved without passing water or the like, and the wind noise is reduced.

[0009]

[Effect of the Invention] Since the present invention is configured as described above, the glass run is not pulled out and falls off at the time of high-speed running of the vehicle, and the sealing performance is improved, the appearance is improved, and the windbreak is improved. This has the effect of reducing sound.
