Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle door seal structure, and more particularly to a so-called center pillar door vehicle seal structure in which a center pillar is eliminated.

[0002]

2. Description of the Related Art As shown in FIGS. 8 and 9, a front door F is attached to a door opening 1 of a center pillarless vehicle by a hinge as usual, and a slide type rear door R is attached to the rear of the front door F. . A roof side weather strip 16 is attached to the roof side rail 2 in the door opening 1, a front door weather strip 14 is attached to the front door F, and a rear door weather strip 15 is attached to the rear door R.

The above-mentioned conventional roof side weather strip 16 is substantially entirely extruded and has a molding connection 16a at the lower portion of the door. Each of the front door weather strip 14 and the rear door weather strip 15 is elastically contacted when the door is closed. Front side corner part 14a of the upper end
The rear side corner portion 15 and the rear side corner portion 15 are both molded and form a T-shaped mating portion T when the door is closed.

[0004]

However, in the T-shaped mating portion T, rainwater W or the like enters from the outside of the vehicle as shown by the arrow from the gap S generated when the door is closed as shown in FIG. There was a problem of leakage. Further, as shown in FIG. 11, rainwater W contacts the hollow portion 16a of the roof side weather strip 16 and the front side corner portion 14a and the rear side corner portion 15 of the upper ends of the front door weather strip 14 and the rear door weather strip 15, respectively. When it hits the surface, part of it is received by the pans 10 and 11, but there is also a problem that part of it is flooded into the room. In view of the conventional problems, it is an object of the present invention to provide a vehicle door seal structure that prevents water from entering when the door of a center pillarless vehicle is closed.

[0005]

To achieve the above object, the structure of the present invention is, as shown in FIG. 1, a roof side weather strip 3 attached to a roof side rail 2 of a door opening 1 of a center pillarless vehicle. And a sealing structure for a vehicle door in which a T-shaped mating portion T is formed by the front door weather strip 4 and the rear door weather strip 5 which are elastically contacted with the door when the door is closed,
When the door is closed, the roof side weather strip 3 is provided with a canopy lip 6 by molding so as to cover the upper ends of the molded corner portions 4a, 5a of the upper ends of the front door weather strip 4 and the rear door weather strip 5. It is provided integrally. Further, the block 7 is provided below the hollow seal portion 3a of the roof side weather strip 3. Further, drain holes 8 and 9 are formed in the corner portions 4a and 5a of the front door weather strip 4 and the rear door weather strip 5, respectively.

[0006]

Embodiments of the present invention will now be described in detail with reference to the drawings. 1 to 3, a roof side weather strip 3 formed by extruding most of the whole is mounted on a roof side rail 2 of a door opening 1 of a center pillarless vehicle. Further, a molded front side corner portion 4a is formed on the upper end of the front door weather strip 4 mounted on the front door F, and a molded front corner portion 4a is formed on the upper end of the rear door weather strip 5 mounted on the rear door R. A rear-side corner portion 5a is formed.

When the door is closed, a T-shaped mating portion T is formed on the roof side weather strip 3 by the front side corner portion 4a and the rear side corner portion 5a which are elastically contacted with each other.
An eaves-shaped lip 6 is integrally formed on the roof side weather strip 3 by molding so as to cover the upper ends of the corner portions 4a, 5a. Also, FIG.
As shown in, the hollow seal portion 3a of the weather strip 3
A block 7 is provided below the. Further, water drain holes 8 and 9 are formed in the corner portions 4a and 5a, respectively, and water receiving trays 10 and 11 are arranged below them. In the figure, black and white triangle marks indicate the boundary between the extrusion molding portion and the die molding portion.

With the above structure, when the rainwater W enters from the gap S of the joining portion T when the door is closed, the eaves-shaped lip 6 first prevents the rainwater W from being directly hit, and the rainwater W having weakened momentum is generated. As shown by the arrows, the water passes through the water drain holes 8 and 9, further flows down, and as shown in FIGS. 6 and 7, is discharged to the outside of the vehicle through the block 7 and the water trays 10 and 11.

The above-described embodiment will be described in more detail with reference to FIGS. In FIG. 5, when the front door F and the rear door R are closed, the front side corner portion 4a, the rear side corner portion 5a, and the hollow portion 3a of the roof side weather strip 3 come into contact with each other and the gap S is left between them.
1 occurs. The eaves-shaped lip 6 prevents a direct hit of water entering from outside the vehicle. The water that has entered through the gap S2 generated between the front side corner portion 4a and the eaves-shaped lip 6 travels in the extrusion molding portion of the front door weather strip 4 through the drain hole 8 provided in the front side corner portion 4a. It is discharged outside the vehicle. The water that has entered through the gap S2 generated between the rear-side corner portion 5a and the eaves-shaped lip 6 travels through the drainage hole 9 provided in the rear-side corner portion 5a through the extrusion-molded portion of the rear door weather strip 5 and is outside the vehicle. Is discharged to. In FIG. 6, in the section a in FIG. 5, water droplets that have bleeded and dropped from the contact surface between the front side corner portion 4a and the roof side weather strip 3 are discharged from the block 7 through the water receiving tray 10 to the outside of the vehicle. In FIG. 7, in the section b in FIG. 5, water droplets that have oozing and dropped from the contact surface between the rear side corner portion 5a and the roof side weather strip 3 are discharged from the block 7 through the water receiving tray 11 to the outside of the vehicle.

[0010]

According to the vehicle door seal structure of the present invention, the eaves-shaped lip is projected on the roof side weather strip at the T-shaped mating portion of the weather strip formed when the door of the center pillarless vehicle is closed. The rainwater is prevented from hitting directly from the gap between the skis, and the rainwater is guided to the drain hole and the water pan so that the rainwater is effectively discharged to the outside of the vehicle.
