Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door opening weather strip provided at a door opening, a roof side weather strip provided at a roof side, and a door weather strip provided at the bottom and front and rear sides of a door. The present invention relates to a door weatherstrip structure of an automobile such as a press door car having an opening seal composed of a thestrip as a main seal.

[0002]

2. Description of the Related Art In a door weather strip structure of this type, as shown in FIGS. 1 and 4, a front side of a front door 1 mounted on a door panel 1b of a fender 2 in a state where its outer surfaces are aligned and closed. The door weather strip portion 6a contacts the rear end surface 8d of the front pillar 8, and the corner portion of the door panel 1b contacts the door opening weather strip 3 mounted on the flange of the front pillar 8.

[0003]

In such a sealed state, the front end face 1a of the door panel 1b and the rear end face 8 of the front pillar 8 are disposed between the weather strip portions 3 and 6a.
A space 7 surrounded by d is formed. Therefore, the air flowing along the fender 2 and the front pillar 8 when the vehicle is traveling at high speed passes through the space portion 7 and the front pillar 8
There is a problem that wind noise is generated by flowing into between the roof side weather strip and the door opening weather strip 3 provided on the roof side rail that is connected to the above.

In view of the above points, the present invention has an object of providing a weather strip structure for an automobile which prevents wind noise caused by airflow in the space between the rear end face of the front pillar and the front end face of the door panel. .

[0005]

In order to achieve this object, the present invention provides a door opening weather strip provided at a door opening and a roof side weather provided at a roof side according to claim 1. The roof side weather strip is composed of a strip and door weather strips provided on the bottom and front and rear sides of the door, and the roof side weather strip bends diagonally from the windshield along the fender to the horizontal direction. In a vehicle door weatherstrip structure that extends to the vicinity, at the end of the front door weatherstrip portion that extends upward from the bottom door weatherstrip portion of the front door, to the roof side weight that extends to the vicinity of the curved portion. Extends upward from the end so that it contacts the strip part, and bulges the cross section Characterized in that the formation of the Jo of the seal portion.

The seal portion closes the space formed between the door panel and the front panel when the front door is closed, and suppresses the inflow of air intruding from below into the space.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An automobile door weather strip structure according to an embodiment of the present invention will be described with reference to FIGS. 1 to 4. As shown in FIG. 1, this door weatherslip structure includes a door opening weatherstrip 3 provided on the entire circumference of a door opening and a drip channel provided on a horizontal roof side rail along the roof. It comprises a roof side weather strip 5 provided over the front pillar 8, and both door weather strips 6 provided at the bottom of the front and rear door panels and both front and rear sides. The roof side weather strip 5 is a pillar bent portion 8c that bends from a diagonal portion 8a along the windshield 9 of the front pillar 8 to a horizontal portion 8b along the fender 2.
Extends to the vicinity.

On the other hand, a front door weather strip portion 6a extending upward in an inverted L-shape from the bottom door weather strip portion 6b of the door panel 1b of the front door 1 is formed.
A seal portion 10 extending upward along the oblique portion 8a of the front pillar 8 is formed at the end of the above so as to contact the roof side weather strip 5 extending near the pillar curved portion 8c. This seal part is molded in a hollow shape so as not to make the closing load excessive when the door is closed.
Further, the door weather strip portion 6a is formed so as to bulge out corresponding to the cross-sectional shape of the space portion 7 so that it does not interfere when the door is closed. The length of the seal part 1
The gap formed around 0 is set so as to exhibit a sufficient air resistance against the airflow that is about to flow into the roof side rail along the front pillar 8. By the way, if the end of the front portion 6a of the door weather strip is bulged without extending so as to close the space portion 7 at a lower position, the mold forming portion corresponds to an air inflow space that becomes large. Is increased, and the closing load of the door is also increased, which is not preferable.

As a result, the seal portion 10 comes into contact with the roof side weather strip 5 when the front door 1 is closed, so that the space between the roof side weather strip 5 and the front end face 1a of the door panel 1b is completely closed. Due to the bulging shape, most of the space 7 between the door panel 1b and the front pillar 8 is closed, and the space 7 is closed.
The air that has entered into the roof side rails is suppressed from flowing into the roof side rails, and the generation of wind noise is suppressed.

[0010]

According to the first aspect of the present invention, the space formed between the front panel and the door panel connected to the roof side rail has an additional shape and a corresponding shape due to the seal portion formed on the upper part of the door weather strip. The closing load of the door is not increased, and the door is closed when the door is closed to prevent wind noise. According to the invention of claim 2, it is possible to further suppress the closing load when the door is closed and effectively suppress the air inflow.
