Abstract

PURPOSE: To prevent the occurrence of water leakage and air noise, by closely attaching a door glass and a secondary seal projection part. CONSTITUTION: A hollow seal part 45 is integrally joined with the undersurface of a basic bottom part 41 and the surface on the car outside of a pillar part 42, and consists of an upper part 46 having a primary seal surface S for receiving the upper end surface of a closed door glass 30 and a lower part where a secondary seal projection part L which makes the springy contact with the surface on the car inside of the door glass 30, at the lower end on the car outside. The upper part 46 and the lower part 47 are partitioned by a bridge B, and the bridge B is inclined aslantly upward toward the car inside from the car outside, and the sectional shape in the joint of the primary seal surface S and a two-piece seal projection part L is formed to a wave shape. Further, the angle α between the primary seal surface S and the bridge B and the angle βbetween the secondart seal surface L and the bridge B are set to the following relation: α<90<β. Accordingly, the door glass and the secondary seal projection part can be closely attached, and the occurrence of water leakage and air noise can be prevented.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a cabside weather strip which is attached to an opening edge of a body of a hard top vehicle and seals with a door glass.

[0002]

2. Description of the Related Art Conventionally, as shown in FIGS. 1 and 2, it is mounted via a retainer 20 attached to a body opening edge 10 with a screw 90 or the like so as to seal between a door glass 30 and the body opening edge 10. As the cab side weather strip 40 of the configured hard top vehicle, one having the following configuration is used.

That is, 41 is a base portion which is fitted to the retainer 20, 42 is a hollow column portion which projects substantially downward inside the base portion 41, and 45 is a lower surface of the base portion 41 and a column portion 42. An upper portion 46 having a primary sealing surface S which is a hollow seal portion integrally connected to an outer surface and receives an upper end surface of the closed door glass 30, and a door glass 3 at a lower end on the outside of the vehicle.
It is composed of a lower portion 47 which forms a secondary seal convex portion L which makes elastic contact with the vehicle inner surface of 0, and the upper portion 46 and the lower portion 47 are separated by a substantially horizontal bridge B. The pillar 4
A lip 48 is provided at the lower end of the inner side of the vehicle 2 for elastically contacting an interior trim 50 that covers the flange 11 projecting downward on the inner side of the body opening edge 10.

However, in the conventional cab side weather strip 40, when the door glass 30 is closed and the upper end surface thereof is elastically attached to the primary sealing surface S of the upper portion 46 of the hollow sealing portion 45, the lower portion 47 is There is a problem that the secondary seal protrusion L is pulled inside the vehicle, and a gap G is generated between the inner surface of the door glass 30 and the secondary seal protrusion L, causing water leakage and wind noise.

[0005]

A problem to be solved is that the conventional cabside weather strip 40 described above is used.
When the door glass 30 is closed, a gap G is generated between the inner surface of the door glass 30 and the secondary seal convex portion L, and water leakage /
It is to make wind noise.

[0006]

Means for Solving the Problems An explanation will be given with reference to FIGS. Retainer 20 attached to body opening edge 10
A hollow pillar portion 42 is provided so as to project substantially downward in the vehicle interior of the base portion 41 that is fitted to the hollow base portion 41, and a hollow seal portion 45 is integrally coupled to the lower surface of the base portion 41 and the vehicle exterior surface of the column portion 42. And the hollow seal portion 45 is elastically contacted by the bridge B with the upper portion 46 having the primary seal surface S that receives the upper end surface of the closed door glass 30 and the vehicle outer lower end with the vehicle inner surface of the door glass 30. A cab side weather strip for a hard top vehicle, which is separated from a lower portion 47 on which a secondary seal convex portion L is formed, wherein the bridge B is inclined obliquely upward from the vehicle exterior side to the vehicle interior side, and The angle α between S and the bridge B, the angle β between the secondary sealing surface L and the bridge B are α <90 ° <β, and the cross-sectional shape of the primary sealing surface S and the secondary sealing convex portion L is corrugated. It is formed by.

[0007]

EXAMPLES Examples will be described. 10 is a body opening edge of a hard top vehicle, 20 is a retainer attached to the body opening edge 10 with screws 90 or the like, 30 is a door glass for opening and closing in the vertical direction, and 40 is a door thereof. A cab side weather strip that seals between the glass 30 and the body opening edge 10, and is configured as follows.

That is, 41 is a base portion which is fitted to the retainer 20, 42 is a hollow column portion which projects substantially downward inward of the base portion 41, and 45 is the bottom surface of the base portion 41 and the column portion 42. An upper portion 46 having a primary sealing surface S which is a hollow seal portion integrally connected to an outer surface and receives an upper end surface of the closed door glass 30, and a door glass 3 at a lower end on the outside of the vehicle.
0 is formed by a lower portion 47 forming a secondary seal convex portion L that makes elastic contact with the inside surface of the vehicle, and the upper portion 46 and the lower portion 47 are separated by a bridge B, and the bridge B is from the outside of the vehicle. The cross section of the primary seal surface S and the secondary seal convex portion L is formed in a corrugated shape while being inclined obliquely upward toward the inside. The angle α between the primary seal surface S and the bridge B and the angle β between the secondary seal surface L and the bridge B are α <90 ° <β.

A lip 48 is provided at the lower end of the pillar portion 42 on the inner side of the vehicle so as to make elastic contact with an interior trim 50 that covers the flange 11 projecting downward on the inner side of the body opening edge 10.

The operation will be described. Door glass 30
When the door glass 30 is closed and the upper end of the door glass 30 is pressed against the primary seal surface S as indicated by the arrow X, the bridge B pivots upward with the end on the inside of the vehicle as an axis, as indicated by the arrow Z, and the secondary seal protrudes. The part L rotates upward about its root, and its tip receives a force to the outside of the vehicle as indicated by an arrow Y, and the amount of wrap increases, so that the part L is pressed against the inner surface of the door glass 30, and a gap is formed between them. It does not occur and therefore does not cause water leaks or wind noise.

[0011]

Since the present invention is configured as described above,
The door glass 30 is closed, and the upper end of the door glass 30 is 1
When it is pressed against the next sealing surface S and deformed, the door glass 3
0 and the secondary seal convex portion L are in close contact with each other, no gap is formed between them, and water leakage and wind noise are not caused.
