By the way, in recent vehicles, there is a tendency to improve the airtightness in the vehicle interior. However, as the airtightness in the vehicle interior is improved, the vehicle interior is closed when the door is closed. It is known that the airtight phenomenon that the atmospheric pressure becomes high occurs and the opening / closing feeling of the door is impaired.

As a means for coping with this, a ventilator is installed in the vehicle to discharge the air in the passenger compartment to the outside of the passenger compartment when the door is closed. Due to the further improvement of the airtightness of the room, the airtight phenomenon may not always be sufficiently prevented by the means for installing the ventilator.

For this reason, it is conceivable to increase the weight of the door to adopt a means for improving the closing characteristic of the door. However, such means increases the weight of the vehicle and increases the cost of the vehicle. Become.

Therefore, an object of the present invention is to improve the sealing structure between a door panel and a window glass of a vehicle door,
It is to add a function to eliminate the etatite phenomenon in the passenger compartment.

DISCLOSURE OF THE INVENTION The present invention is a windshield in which weather strips are respectively attached to upper end portions of an outer panel and an inner panel which form a door panel of a vehicle door, and vertically penetrate between the both panels. The lip portion of the first weatherstrip attached to the outer panel is elastically abutted on the outer surface of the second panel and the lip portion of the second weatherstrip attached to the inner panel on the inner surface of the windshield. In a sealing structure in which the door panel and the window glass are sealed by elastically contacting each other, the lip portion of the first weather strip is formed in a protruding shape that inclines upward to the window glass side. Resiliently contact the outer surface of the glass,
In addition, the lip portion of the second weather strip is formed in a protruding shape that inclines downward toward the window glass, and is elastically abutted against the inner surface of the window glass.

[0009]

In a vehicle door in which the above-described sealing structure is adopted as the sealing structure between the door panel and the windshield, the lip portions of both the first and second weather strips are usually inside and outside the windshield. It is elastically abutted on the side and seals between the door panel and the windshield.

When the door in the open state is closed, the air pressure in the vehicle compartment increases as the door rotates toward the vehicle compartment, and the inner pressure increases as the air pressure in the vehicle compartment increases. The lip portion of the second weatherstrip mounted on the panel side bends inward due to the pressure difference between the inside and outside of the passenger compartment and separates from the inside surface of the windshield, and the gap between the lip portion of the weatherstrip and the windshield Create a gap in.

As a result, the air in the passenger compartment is discharged to the outside of the passenger compartment through the gap, and the airtight condition in the passenger compartment is eliminated. Therefore, when the door is closed, the occurrence of the airtight phenomenon in the vehicle interior is suppressed, and the opening / closing feeling of the door is prevented from being deteriorated.

On the other hand, with respect to the first weather strip assembled on the outer panel side of the door panel, when the air pressure in the vehicle compartment acts through the gap between the window glass and the lip portion of the second weather strip, the lip portion Bends upward and away from the outer surface of the windshield, creating a gap between the lip of the weatherstrip and the windshield. As a result, the air in the passenger compartment is discharged to the outside of the passenger compartment through this gap, and the airtight state in the passenger compartment is eliminated.

As described above, if the sealing structure is adopted as the sealing structure for the vehicle door, the weight of the door is increased and the cost is increased only by considering the shape of at least the lip portion of the second weatherstrip of both weatherstrips. It is possible to suppress the occurrence of the airtight phenomenon in the vehicle interior when the door is closed, without increasing the value of.

BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be described below with reference to the drawings. FIG. 1 shows an example of a seal structure according to the present invention. The sealing structure is a sealing structure of the upper end portion of the door panel 10a in the vehicle side door 10 shown in FIG. 2, and corresponds to the sealing structure shown in the vertical section in FIG.

In the seal structure, weather strips 13 and 14 are respectively attached to the upper end portions of the outer panel 11 and the inner panel 12 constituting the door panel 10a of the side door 10, as in the conventional side door. The strip body 13 of the first weather strip 13 assembled to the outer panel 11 side is attached to the outer surface of the window glass 15 that vertically penetrates between the panels 11 and 12.
The lip portion 13b protruding from a is resiliently contacted, and the lip portion 14b protruding from the strip body 14a of the second weather strip 14 assembled to the inner panel 12 side is provided on the inner surface of the window glass 15. It is elastically abutted.

The lip portion 1 of the first weather strip 13
3b is formed in a protruding shape that is inclined upward toward the window glass 15 side, and the upper end portion thereof is elastically abutted on the outer side surface of the window glass 15. Further, the lip portion 14b of the second weather strip 14 is provided with the window glass 15
It is formed in a protruding shape that inclines downward to the side, and the lower end portion thereof is elastically abutted against the inner side surface of the window glass 15. As a result, the weather strips 13 and 14 seal the space between the door panel 10a and the window glass 15.

The seal structure having the above construction is used for the door panel 10.
In the normal state, the side door 10 employed for the sealing structure between the a and the windshield 15 is such that the lip portions 13b, 14b of the first and second weather strips 13, 14 are resilient to the inner and outer side surfaces of the windshield 15. And a seal is provided between the door panel 10a and the window glass 15.

When the door 10 in the open state is closed, the air pressure in the vehicle compartment increases as the door 10 rotates toward the vehicle compartment, and the air pressure in the vehicle compartment increases. , The lip portion 14b of the second weather strip 14 assembled on the inner panel 12 side bends downward as shown by a chain double-dashed line due to the pressure difference between the inside and outside of the passenger compartment, and the inner surface of the window glass 15 And a gap is formed between the lip portion 14b of the weather strip 14 and the window glass 15.

As a result, the air in the passenger compartment is discharged to the outside of the passenger compartment through this gap, and the airtight condition in the passenger compartment is eliminated. Therefore, when the door 10 is closed, the occurrence of the airtight phenomenon in the vehicle interior is suppressed, and the opening / closing feeling of the door 10 is prevented from being deteriorated.

On the other hand, the outer panel 1 of the door panel 10a
In the first weather strip 13 assembled on the first side, when the air pressure in the vehicle compartment acts through the gap between the window glass 15 and the lip portion 14b of the second weather strip 14, the lip portion 13b is As shown by the dotted line, it bends upward and away from the outer surface of the window glass 15, creating a gap between the lip portion 13b and the window glass 15. As a result, the air in the passenger compartment is discharged to the outside of the passenger compartment through this gap, and the airtight state in the passenger compartment is eliminated.

As described above, if the seal structure is adopted, the weight of the door 10 is increased and the cost is increased only by considering the shape of at least the lip portion 14b of the second weather strip 14 of both weather strips 13, 14. It is possible to suppress the occurrence of the airtight phenomenon in the vehicle interior when the door 10 is closed without increasing the number.
