BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a seal structure for a back door of a motor vehicle, and more particularly to a seal structure for an upper edge portion of a module glass back door.

[0002]

2. Description of the Related Art Water flow from a gap between a door edge and an edge of an opening of a vehicle body can be prevented by preventing wind noise when the automobile is running.
Sealing of doors having a function of preventing dust and sound from penetrating into the vehicle has been performed with a weather strip or the like. The conventional seal structure will be described with reference to FIG. A sealing lip 8 is extended from a weather strip 9 attached to the door side together with a molding 7 for attaching the glass 5 to the door frame 3 and brought into contact with a molding 10 provided on the vehicle body side. The gap G between the opening and the door is sealed. Alternatively, as shown in FIG. 5, a coating layer 31 covering the door frame 3
The structure in which the seal lip 35 and the seal lip 35 are integrally formed and the seal lip 35 is brought into contact with the molding 36 on the vehicle body side to execute the seal is disclosed in Japanese Utility Model Laid-Open No. 2-2103.
No. 2 discloses this.

[0003]

However, the former seal described in the above-mentioned prior art has a seal lip 8 in the gap between the vehicle body and the door frame, so that the appearance is poor and the weather is poor. The production of the strip 9 varied, and there was a problem in durability. Also, in the latter seal structure, it was difficult to integrally form the cover layer 31, the glass run 33, and the seal lip 35. In addition, vehicle doors (such as trunk rooms)
The seal structure is disclosed in Japanese Utility Model Laid-Open No. 63-179226,
No. 58-122239. these
The seal structure is configured so that the vehicle body and the weather strip are in contact with each other.
Rain water hits the edge of the vehicle directly, causing rust
There was an inconvenience to do. Thus, the present invention is simple to manufacture and reliably achieves the sealing effect of the gap, and the edge of the vehicle body is rained.
An object of the present invention is to provide a seal structure of an upper edge portion of a back door which protects from water and has a decorative effect.

[0004]

SUMMARY OF THE INVENTION The seal structure of the upper edge of the back door of the automobile according to the present invention has a weather strip attached to the edge of the roof panel and a frame at the opening of the back door.
The molding comprises a holding portion for holding the edge of the module glass supported and disposed by the system, a groove, and a plate-like contact portion extending in the weather strip direction.
The frame for supporting the module glass has an adhesive surface parallel to the back door module glass, and a locking portion formed along the edge of the back door module glass and perpendicular to the adhesive surface, The rudging has a structure in which the holding portion holds the edge of the module glass, the locking portion of the frame is locked in the groove portion, and the contact portion is arranged on the edge of the door with the weather strip direction. Have.

[0005]

When the back door of an automobile is closed, the contact portion of the molding mounted on the module glass on the back door side deforms the hollow portion on the vehicle body side and makes a line contact with the side surface of the corresponding weather strip. Between the car body and the back door
And the contact part of the molding is engaged with the groove.
Reinforced by the locking part of the frame to be stopped
Prevents deformation of contact parts .

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings.
1 is a perspective view of an automobile equipped with a back door according to the present invention, FIG. 2 is a cross-sectional view taken along a line AA in FIG. 1, and FIG. 3 is a cross-sectional view of an upper edge portion of the back door.

A back door is mounted on the rear opening of the vehicle body 20. The two back doors 21 and 22 shown in this embodiment are doors that open and close in a double door manner by connecting the left edge of the back door 21 to the vehicle body by a hinge and connecting the right edge of the back door 22 to the vehicle body by a hinge. . The back doors 21 and 22 are provided with a door frame 40 at the opening of the door.
Supports the module glass 25. A molding 30 is mounted on the periphery of the module glass 25. The molding 30 is a long body made of synthetic resin and has a holding portion 31 for holding an edge of the glass 25 on one side, and a contact portion 3 having a curved end at the other end with a groove 32 interposed therebetween.
Form 3 The molding 30 is located at one end.
The edge of the module glass 25 is held between the holding portions 31 and the other end is held.
The contact portion 33 is arranged so as to contact the roof panel 50.
I do. Module with molding 30 attached to the edge
The glass 25 is fixed to the door frame 40 via an adhesive 35.

[0008] Doafure - arm 40 has a closed cross section portion 41 located inside the vehicle body, modules - an adhesive surface 42 parallel to Rugarasu 25, in the opposite direction of the bonding surface 42 mode - Rudei
And extends vertically along the edge of the glass 25
It has a locking portion 43 to be provided, and is formed by roll molding. When the bonding surface 42 is bonded to the surface of the glass 25 via the adhesive 35, the end of the locking portion 43 of the door frame 40 is bent toward the edge of the glass 25, and the tip is molded. 30 is engaged with the groove 32. A panel cover 27 is attached to an end portion of the roof panel 50 of the vehicle body 20. The panel cover 27 is disposed continuously to the roof panel 50, and the inside is connected to an end of the headlining 28. A weather strip 60 is attached to the bent portion of the edge of the panel cover 27 by a fixing tool 61. Weather strip 60 is formed of an elastic body made of synthetic resin,
It is a long body having a hollow portion 62 having a shape shown by a solid line in a free state, and is deformed into a shape shown by a broken line by contact with a counterpart.

In the upper edge of the back door configured as described above,
WearingIsThe seal structure is that the doors 21 and 22 are closed.

In consideration of the followability when the lip 60 deforms, a smooth shape
It is required that there be.

[0010] As described above, the back door shown in Example - Le structure, module - motor is mounted on the tip of Rugarasu 25 - and Rudeingu 30, the vehicle body 20 Le - off path
And a weather strip 60 attached to the edge of the panel 50
This is a configuration in which a reliable seal is achieved by abutment, and a seal structure in which the number of parts is reduced. In addition, the contact portion 33 of the molding 30 is pressed against the surface of the weather strip 60 in a line contact state so that the external appearance is good and the contact portion 33 has good external appearance.
And maintain a reliable contact state without deformation. Further
The upper edges of the doors 21 and 22 are covered with the molding 30.
It is covered, so that rainwater can directly hit the door end.
Rust on the door body can be prevented.

[0011]

The seal structure of the upper edge portion of the back door of the present invention achieves a reliable sealing effect with a simple structure of only the molding on the door side and the weather strip on the vehicle body side. Further, the weatherstrip can appropriately cope with the pressure contact of the molding contact portion in the hollow portion, and the plate-like contact portion of the molding is formed by the locking portion of the frame which is locked in the groove portion. The movement is prevented, and the line is securely in line contact with the side surface of the weather strip, and the gap between the door and the roof panel is reduced.
Close . As described above, the seal portion of the present invention is different from the conventional seal in that the seal lip is seen between the molding and the weather strip and the appearance is poor. Since the contact portion is sealed in line contact with the weather strip, the decorative effect is improved in appearance , and the upper edge of the door is covered with molding.
Doors do not come into direct contact with rainwater,
Can be prevented.
