Abstract

PROBLEM TO BE SOLVED: To hold sufficient sealing performance by forming a bent part of approximately S-shape at a seal wall of a hollow seal part, near a root part to an outer lip, and forming a stepped notch and a thin-walled part near a root part to a glass run body part. SOLUTION: In a seal wall 4 of a hollow seal part 3 coming in elastic contact with ascending door glass G, a bent part 5 of approximately S-shape is formed near a root part to an outer lip 2, and a stepped notch 6 and a thin-walled part 7 are formed near a root part to a glass run body 1a. Accordingly, when the door glass G comes in elastic contact with the seal wall 4, the stepped notch 6 and the thin-walled part 7 are immediately bent even in the case of having dispersion in the interior-exterior direction of an arrow mark H. Load during the ascent of the door glass G is thereby reduced, and the door glass G ascends higher, and even if the door glass G comes in contat with the seal wall 4 with small load, the outer lip 2 is immediately bent by the bent part 5 of approximately S-shape so as to come in close contact with the door glass G.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a glass run for automobile doors.

[0002]

2. Description of the Related Art In an automobile door D shown in FIG. 3, a flash surf-ace type glass run 17 is attached to a door sash 16 by a vertical main body 18 as shown in FIG. A hollow seal portion 20 which receives G and has an outer lip 19 provided on the outer side of the vehicle and which has a substantially rectangular cross section is provided at the upper end of the main body portion 18 so as to project. When the door glass G is completely closed as shown in FIG. 5 (a), the outer lip 19 is brought into close contact with the surface of the door glass G to maintain sufficient sealing and appearance.

[0003]

However, in the structure of the hollow seal portion 20, as shown in FIG. 5 (b), the door glass G is hollow due to the variation in the indoor / outdoor direction when the door glass G rises. If the seal wall 21 of the annular seal portion 20 cannot come into contact with the correct position, the outer lip 19
And the surface of the door glass G are opened, the sealing property and appearance are insufficient, and even when the closing of the door glass G is incomplete and the amount of pressure contact with the sealing wall 21 is insufficient, the sealing property is insufficient. There is a problem that it becomes. Therefore, in view of the conventional problems, it is an object of the present invention to provide a glass run for an automobile door in which the outer lip is always in close contact with the door glass and a sufficient sealing property can be maintained when the door glass is closed.

[0004]

In order to achieve the above object, the structure of the present invention is, as shown in FIG. 1, a door which is raised outside the vehicle at the upper end of the grass run main body 1a held by the door sash F. In a glass run 1 for an automobile door, which receives a top edge of a glass G and has a hollow seal portion 3 having a substantially quadrangular cross section and having an outer lip 2 on the outside of the vehicle, a door glass G of the hollow seal portion 3 is provided. The seal wall 4 that elastically contacts with the outer lip 2 forms a substantially S-shaped bent portion 5 in the vicinity of the root portion thereof, and the stepped notch 6 and the thin portion 7 in the vicinity of the root portion of the grass run main body 1a.
Or a notch 14 and an inverted U-shaped bent portion 15 are formed.

[0005]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 shows a first embodiment of the present invention, in which 1 is a glass run for an automobile door, which is an outer side of a vehicle having a substantially quadrangular cross section outside the vehicle at the upper end of a longitudinal glass run main body 1a held by a door sash F. A hollow seal portion 3 having a lip 2 is provided in a protruding manner. And the rising door glass G
The seal wall 4 of the hollow seal portion 3 elastically contacting with the above forms a substantially S-shaped bent portion 5 in the vicinity of the base portion with the outer lip 2, and a stepped notch in the vicinity of the base portion with the grass run main body 1a. 6 and a thin portion 7 are formed. Reference numeral 8 is a lip seal portion, and 9 is a sub seal.

With the above structure, when the door glass G rises and makes elastic contact with the seal wall 4, even if the door glass G cannot contact the correct position of the seal wall 4 due to the variation in the indoor and outdoor directions of the arrow H, the stepped notches 6 and Since the thin portion 7 is bent, the load when the door glass G rises is small, that is, the load-up curve becomes gentle and the door glass G rises higher. Further, since the substantially S-shaped bent portion 5 is formed in the vicinity of the base of the outer lip 2, even if the door glass G abuts the seal wall 4 with a small load when rising,
The outer lip 2 bends immediately and comes into close contact with the door glass G to ensure the seal.

FIG. 2 shows a second embodiment. When the dimension L of the hollow seal portion 10 is longer than that of the first embodiment, stress is not concentrated when the door glass G comes into contact with the seal wall 11.
In addition, a substantially S-shaped bent portion 13 is formed near the base of the outer lip 12, a notch 14 is formed near the center of the seal wall 11, and an inverted U is formed near the base of the glass run main body 1a. The character-shaped bent portion 15 is formed. The operation and effect of this embodiment are substantially the same as those of the first embodiment.

[0008]

As described above, in the glass run for an automobile door according to the present invention, since the substantially S-shaped bent portion or notch is formed in the seal wall of the hollow seal portion, the lifted door glass comes into contact with the glass run. Then, the seal wall is easily bent, and the outer lip immediately comes into close contact with the door glass. Therefore, even when the door glass varies in the indoor / outdoor direction and cannot come into contact with the seal wall at the correct position, the outer lip is always brought into close contact with the door glass to improve the sealing property and the appearance.
