DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door weather strip mounted around an automobile door.

[0002]

2. Description of the Related Art FIG.
As shown in FIG. 3, an extruded weather strip (hereinafter, referred to as a first weather strip) mounted from the outer periphery of the door panel 1 to the rear vertical frame of the door sash 2.
3A and an extruded weather strip (hereinafter referred to as a second weather strip) 3B mounted on the door sash 2
And a weatherstrip 3 which is connected in a loop.

By the way, these weather strips 3A, 3
B cannot be directly connected because the cross-sectional shape is different. Therefore, at the upper corner portion and the front end of the belt line 10 of the door, the second weather strip is formed from the terminal cross-sectional shape of the first weather strip 3A. They are connected via molding connection parts 3C and 3D whose sectional shape gradually changes to the terminal sectional shape of 3B.

[0004] These connections are performed by inserting the terminals of both weather strips 3A and 3B into both ends of a mold cavity for molding the molding connection portion 3C (or 3D) and injecting molding material into the cavity. It is done by.

[0005]

However, since this molding connection requires a lot of man-hours, there is a need for a low-cost door weather strip with higher productivity. The present invention has been made to meet this demand.

[0006]

SUMMARY OF THE INVENTION The present invention relates to a door panel 1 as shown in FIG. 1, in particular, FIGS. 1 (A) and 1 (C).
The front upper terminal 30a of the first weather strip 3A along the outer periphery of the first weather strip 3A and the front lower terminal 30b of the second weather strip 3B along the door sash 2 are not formed and connected by molding. The belt line 10 of the door panel 1
In front of the second weather strip 3B
Connect the subordinate terminal 30b to the lower front part of the first weather strip 3A.
It is arranged outside the terminal 30a in the thickness direction of the door panel 1 on the vehicle outside.
In addition, the two terminals 30a and 30b are characterized in that the opposing side surfaces are overlapped.

[0007]

By eliminating the molding at one of the connecting portions of the door weather strip, the productivity of the door weather strip is improved and the cost is reduced.

[0008]

1 and 2 show an embodiment of the present invention. The door weather strip 3 includes a first weather strip 3 </ b> A that is serially mounted along the outer periphery of the door panel 1 of the front door and the rear vertical frame of the door sash 2, and a first weather strip 3 </ b> A that is mounted along another part of the door sash 2. 2 weather strips 3B.

The first weather strip 3A is an extruded body of sponge rubber, and has a base 31, a hollow seal portion 32 and a seal lip 33. The second weather strip 3B is also an extruded body of sponge rubber, and has a base 31 and a hollow seal portion 32 having substantially the same cross-sectional shape as the first weather strip 3A, and a seal lip 34 extending longer than the seal lip 33. It has. The rear ends of both weather strips 3A and 3B are connected to each other in a corner shape through a molded connection portion 3C.

[0010] The first weather strip 3A is fixed to the outer periphery of the door panel 1 at a portion along the outer periphery of the door panel 1 by a clip (not shown) at a predetermined interval. A portion of the first weather strip 3A along the vertical frame of the door sash 2 and the second weather strip 3B are locked by a retainer 21 provided on the door sash 2.

The front lower end 30b of the second weather strip 3B extends below the door belt line 10, and is fixed to the upper front end face of the door panel 1 by a clip (not shown). On the other hand, front upper terminal 30a of the first weather strip 3A is a front under the bent terminal 30b and abutment positions, further the thickness of the door panel 1 of the lower terminal 30b of the second weather strip 3b The two terminals 30a and 30b that extend in the vehicle interior to the position of the door belt line 10 and overlap are
Opposing sides are stacked so that they are in close contact with each other
You. The upper terminal 30a of the first weather strip 3A is
It is fixed to the upper part of the front end face of the door panel 1 by a clip (not shown).

When the door is closed, the hollow seal portion 32 of the first weather strip 3A is pressed against the door opening edge of the vehicle body including the lower half of the front pillar 4. On the other hand, the second weather strip 3B has a hollow seal portion 32 whose front pillar 4
The upper end of the seal lip 34 presses against the door opening edge of the vehicle body from the upper half portion to the roof side, and the tip of the elongated sealing lip 34 closes the gap opening between the door opening edge and the door sash 2. At the edge of the door panel 1 in front of the belt line 10, the terminals 30a, 30 of the first and second weather strips 3A, 3B are located.
Both of the seal portions 32 b are pressed against the front pillar 4.

[0013]

According to the present invention, the front upper terminal of the weather strip on the door panel side and the lower front terminal of the weather strip on the door sash side constituting the door weather strip are provided.
Since the connecting structure is fixed to the door panel so as to be overlapped in the thickness direction of the door panel, the forming connection is not required, the productivity of the door weather strip is improved, and the cost is reduced. Since the overlapping portion is located at a position which is hidden when the door is closed, the appearance of the vehicle compartment is not impaired.
