DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a run channel for sealing between a door sash of an automobile and a raised door glass.

[0002]

2. Description of the Related Art A description will be given with reference to FIGS. Conventionally, as a run channel 30 for sealing between the door sash 10 and the raised door glass 20, one having the following configuration has been used.

Reference numeral 31 denotes a base portion of the run channel 30, which is attached via a sash or retainer 15 to an outer surface of the main frame 11 having a substantially L-shaped cross section with an open lower portion. Reference numeral 32 denotes a hollow seal portion of the run channel 30 which is connected to the upper side of the upper portion of the base portion 31 and protrudes to the outside of the vehicle to receive the upper end surface of the raised door glass 20. The outer surface of the seal portion 32 extends downward, and a downward outer lip 33 is formed to prevent the door glass 20 from coming off the outer end of the hollow seal portion 32 and to seal the door glass 20. Reference numeral 34 denotes a seal lip which is elastically contacted with the inner surface of the raised door glass 20 and is connected to a lower end of the base 31 and protrudes outward and upward from the vehicle.

[0004] Reference numeral 40 denotes a sub-seal having a substantially U-shaped cross section attached to the upper portion of the main frame 11, and a parting-off seal 41 protrudes upward from the upper surface thereof.

[0005] Reference numeral 12 denotes a subframe having a substantially mouth-shaped cross section formed on the inner surface of the main frame 11, and a main seal 50 is attached to the upper surface thereof via a sash or retainer 16.

The conventional glass run channel is shown in FIG.
When the door glass 20 is raised to the highest position as shown in FIG. When pushed in,
As shown by the arrow Q, there is a problem that the front end portion of the door glass 20 projects to the outside T of the outer lip 33.

[0007]

The problem to be solved is that the above-mentioned conventional glass run channel raises the door glass 20 to the highest position and, when the hollow seal portion 32 is pushed up, the door glass from the inside S of the vehicle. When a force P in the direction T outside the vehicle is applied to the vehicle 20 or a foreign object K is forcibly inserted into the gap between the door glass 20 and the outer lip 33
That is, the front end portion of the door glass 20 comes out to the outer side T of the outer lip 33.

[0008]

A description will be given with reference to FIGS. 1 and 4. In the first invention, an outer lip 33 that contacts the outer surface of the door glass is formed by extending the outer surface of the seal portion 32 that receives the upper end surface of the raised door glass 20 downward to contact the outer surface of the door glass. before and after Wai in the direction
A door having a stiffness 60 in the glass suction direction.
It is buried below the glass tip .

According to a second aspect of the present invention, a door sash 10 is mounted on an upper surface of a base portion 31 which is attached via a sash or a retainer 15 to an outer surface of a main frame 11 having a substantially L-shaped cross section with an open lower portion. A hollow seal portion 3 that is coupled to and protrudes outward from the vehicle and receives the upper end surface of the raised door glass 20.
2 and the outer surface of the hollow seal portion 32 is extended downward to form an outer lip 33, and a wire-like rigid member is formed in the longitudinal direction of the extended outer lip 33.
60 with a glass door in the glass suction direction
It is buried below the end .

[0010]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment will be described. A door sash 10 has a substantially L-shaped cross-section with an open outer and lower part, and a substantially mouth-shaped cross-section attached to the inner surface of the main frame 11. Of sub-frames 12. Reference numeral 20 denotes a door glass, and reference numeral 30 denotes a glass run channel for sealing between the door sash 10 and the raised door glass 20, and is configured as follows.

Reference numeral 31 denotes a base portion attached to the outer surface of the main frame 11 via a sash or retainer 15;
Numeral 2 is a hollow seal portion which is connected to the upper portion of the base portion 31 and protrudes to the outside of the vehicle and receives the upper end surface of the raised door glass 20. Is prevented from coming off the outer end of the seal portion 32,
A downwardly facing outer lip 33 for sealing is formed.

Reference numeral 34 denotes a seal lip elastically contacting the inner surface of the raised door glass 20, and is connected to the lower end of the base 31 and protrudes outward and upward from the vehicle.

The outer lip 33 has a wire-like rigidity over the entire length in the horizontal front-rear direction, that is, in the longitudinal direction.
From the end of the door glass in the glass suction direction
Is also buried below .

Reference numeral 40 denotes a sub-seal having a substantially U-shaped cross section attached to an upper portion of the main frame 11, and a parting-off seal 41 protrudes upward from the upper surface thereof. The sub-seal 40 mounting state will be described in more detail. The upper part of the inner side surface of the main frame 11, the upper surface that is outwardly suspended on the inner side surface, and the downwardly extending surface that is downwardly mounted on the outer end of the upper surface. The outer surface of the hook is covered, and both end portions are hung on the upper portion of the inner surface of the vehicle and the lower end of the hook.

A main seal 50 is attached to the upper surface of the sub-frame 12 via a sash or retainer 16. Further, as shown in FIG. 5, the run channel may be of a type in which a core metal is buried. That is, it may be attached to the door panel flange.

The operation will be described. The outer lip 33 has a wire-like rigidity embedded in the longitudinal direction.
The object 60 raises the door glass 20 to the highest position and applies a force P in the vehicle exterior T direction from the vehicle interior S to the door glass 20 in a state where the seal portion 32 is pushed up, or the door glass 20 and the lip 33 With wire-like rigidity even when trying to forcibly push a foreign object into the gap
Since the deformation of the lip 33 is prevented by 60 , the upper end of the door glass 20 does not come out of the lip 33. The buried position of the wire-shaped rigid member 60 is preferably placed closer to the lip 33 than the glass suction direction XX.

[0017]

Since the present invention is configured as described above, when the door glass 20 is raised to the highest position, the force P in the vehicle exterior T direction from the vehicle interior S to the door glass 20 is applied to the door glass 20.
Or added it is, even when you try to shoehorn the foreign matter is forced into a gap between the door glass 20 and the outer lip 33, the sum
Since the outer lip 33 is prevented from being deformed by the ear-shaped rigid member 60 , the upper end of the door glass 20 does not protrude outside the outer lip 33.
