Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention forms water droplets, which penetrate into the passenger compartment along the upper end of a door weather strip provided on a side edge of a door, between the upper end of the door weather strip and the inner surface of a door glass. The present invention relates to the improvement of the seal structure of a sashless door that discharges water into the door through a drainage passage.

[0002]

2. Description of the Prior Art In a sashless door type vehicle, FIG.
As shown in FIG. 3, the door 1 itself is sealed by a door weather strip 2 provided on the periphery of the door 1, while the door glass 3 is sealed by a vehicle body side weather strip 4 provided on the vehicle body side. At the waist portion of the door 1, the vehicle body side weather strip 4 is pressed against the upper end portion of the door weather strip 2 and the door glass 3, but there is a step due to the thickness at the upper end of the door weather strip 2. Because of the existence of the vehicle body side weather strip 4, a slight gap is formed along the upper end of the door weather strip 2 that communicates with the inside and outside of the vehicle in a state where the vehicle body side weather strip 4 is in pressure contact, and there is a problem that water droplets penetrate through the gap and enter. Therefore, conventionally, as shown in FIG.
At the upper end of the door weather strip 2 provided at the side edge portion, an elongated bulging portion 5 is formed vertically along the inside of the vehicle, and a water draining passage 6 is formed between the door glass 3 and the inner surface of the door glass 3. A seal structure having the above structure has been proposed (Shokaisho 61).
-62618). The drainage passage 6 has an upper end opening to the upper end 2a of the door weather strip 2 and a lower end communicating with the internal space of the door 1. Therefore, the water droplets that have entered along the upper end 2a of the door weather strip 2 are discharged to the internal space of the door 1 through the water drainage passage 6 and further discharged from here to the outside of the vehicle compartment.

[0003]

However, when the water drainage passage 6 is formed on the interior side of the door weather strip 2 as described above, the inside and outside of the vehicle compartment communicate with each other through the water drainage passage 6 and the vehicle travels. Occasionally air flows, which may cause an unpleasant wind noise.

[0004]

SUMMARY OF THE INVENTION Therefore, according to the present invention, a door weather strip is provided at a door side edge of a sashless door, and a door glass is provided at an upper end portion of the door weather strip that comes into contact with the door glass. A bulge is formed so as to form a water drainage passage with the inner surface, and the upper end of the water drainage passage is opened to the upper end of the door weather strip located at the door waist portion, and its lower portion is opened to the door. In the sashless door sealing structure which is communicated with the internal space of the above, a flexible thin-walled air leakage prevention lip is provided inside the water drainage passage so as to cross the water drainage passage. Is characterized by.

[0005]

The water droplets that have entered along the upper edge of the door weather strip are discharged into the inner space of the door through the water drainage passage on the vehicle interior side. Here, the water drainage passage is substantially closed by a wind leakage prevention lip that traverses it, but since the air leakage prevention lip is thin and has flexibility,
Water droplets can flow down between the door glass surface. Then, normally, the water drainage passage is substantially closed by the air leakage prevention lip, so that the air flow is reduced and the air leakage noise is suppressed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail below with reference to the drawings. Since the overall structure of the door weather strip 2 and the like is the same as that of the conventional one, the same parts as those of the conventional one will be denoted by the same reference numerals.

FIG. 2 shows a sealing structure in the waist portion at the rear end of the door 1. A door weather strip 2 formed in a predetermined shape is arranged along the side edge of the door 1. . The upper portion of the door weather strip 2 is fixed to the door panel by clips 7 from two directions, and the upper end portion thereof extends from the outer surface 3a to the inner surface 3b of the door glass 3 as shown in FIG. They are in contact with each other to form a U shape. The vehicle body side weather strip 4 is pressed against this portion as shown in FIG.

A slender bulging portion 5 is formed in the upper and lower portions of the door weather strip 2 along the vertical direction. The bulging portion 5 forms an inner surface 3b of the door glass 3 with the bulging portion 5. A drainage passage 6 is defined between them. The upper end 6a of the drainage passage 6 is open to the upper end 2a of the door weather strip 2 located at the door waist, and the lower part is communicated with the internal space of the door 1 through a door panel opening or the like (not shown). ing. In addition, a drain hole for discharging water droplets that have entered the internal space to the outside of the vehicle is provided at a lower edge (not shown) of the door 1.

Inside the water draining passage 6, a ridge portion 8 is provided along the vertical direction so as to divide the upper end opening 6a into two. The ridge portion 8 is molded integrally with the door weather strip 2, and its tip abuts against the inner surface 3b of the door glass 3 so that the water removing passage 6 is crushed and deformed by the pressure contact of the vehicle body side weather strip 4. It is designed to prevent

Then, at a height position corresponding to the lower end of the protruding portion 8, the inside of the drainage passage 6 is shown in FIGS.
As shown in FIG. 3, a wind leakage prevention lip 9 is provided so as to project.
The air leak prevention lip 9 is a thin wall member formed so as to cross the water drainage passage 6, is integrally molded with the door weather strip 2, and has sufficient flexibility in the vertical direction. . In addition, the leading edge is the inner surface 3 of the door glass 3.
It comes into close contact with b and substantially closes the drainage passage 6. The air leakage prevention lip 9 and the lower end of the protruding portion 8 are separated.

According to the structure of the above-described embodiment, an attempt is made to penetrate the vehicle interior through the gap 10 (see FIG. 1) formed between the vehicle weather strip 4 and the upper end 2a of the door weather strip 2. The water drop is the above drainage passage 6
Is trapped in the upper end opening 6a of the door and discharged into the inner space of the door 1 through the water draining passage 6. Eventually, it is discharged to the outside of the vehicle compartment through the interior space of the door 1. Therefore, water drops will not flow out into the vehicle interior. Here, the drainage passage 6 is in a state in which the middle portion thereof is substantially closed by the air leakage prevention lip 9, but since the air leakage prevention lip 9 is thin and flexible, Due to the flexural deformation, water droplets can flow down between the inner surface 3b of the door glass 3 and the surface.

The water drainage passage 6 communicates with the inside and outside of the vehicle. However, in a normal state, the water drainage passage 6 is substantially closed by the wind leakage preventing lip 9. The air flow is reduced, and the wind leakage noise generated during traveling is suppressed.

[0013]

As is clear from the above description, according to the sashless door sealing structure of the present invention, water droplets that have entered along the upper edge of the door weather strip at the door waist portion are drained through the drainage passage. The water can be discharged into the interior space of the door, and at the same time, the sound of wind leakage generated during traveling can be effectively suppressed by the water drainage passage.
