Description

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 along the door frame of an automobile.

[0002]

2. Description of the Related Art As the above-mentioned door weather strip, a glass seal member for sealing around the door glass and a body seal member for sealing between a door frame and a door opening edge of a vehicle body are provided, and the outer surfaces of both members are covered. As one example, a door weather strip is used that covers the door frame (Jitsukaihei 3-83117).

FIG. 4 shows a typical example thereof, in which a flange 51 extends outwardly of the door frame 5 so as to partition the door glass 7 from the door opening edge 6 of the vehicle body. A glass seal member 3A is attached inside. On the other hand, a body seal member 3B having a substantially U-shaped cross section is attached to the flange 51. Glass seal member 3
A has a hollow seal portion 30 and seals around the door glass 7. The body seal member 3B is provided with a seal lip 32 on the outer surface of the base 31 having a U-shaped cross section, and seals between the door frame 5 and the door opening edge 6 of the vehicle body. The surfaces of both seal members 3A and 3B on the outer side of the vehicle are flush and continuous.

FIG. 5 shows another representative example. The outer end of the flange 51 of the door frame 5 is bent in the vertical direction to form a locking portion 52, and a body seal member having a flat C-shaped cross section is formed on the locking portion 52. One end of the base portion 41 of 4B is hooked and locked. 4A is a glass seal member similar to the glass seal portion 3A, and 42 is a seal lip.

[0005]

By the way, in order to widen the field of view of the door glass from the passenger compartment, the width of the door weather strip composed of the glass seal member and the body seal member is made small, and the width of the door weather strip is reduced accordingly. It is desirable to reduce the width of the door frame. However, it is impossible to make the glass seal member narrower than the present condition due to restrictions such as the stroke of pushing up the door glass, the length of the inner lip 35 (FIG. 4), and the glass contact position.

Therefore, although it is required to reduce the width of the body seal member, in the conventional example shown in FIG. 4, there is a holding lip 33 for sandwiching the flange 51 on the inner surface of the base portion 31 opposed to the base portion 31, and the base portion 31 has a flange therein. The cored bar 34 for strengthening the holding force is embedded and becomes thick, and it is difficult to make the width thinner than the present condition.

In the conventional example of FIG. 5, when the door is closed, a force in the direction of arrow C acts on the seal lip 42 from the door opening edge 6, and a rotational force is applied to the base portion 41 for this reason, so that the locking portion is engaged. If the width of 52 is small, the base 41 will come off. Therefore, the width of the seal member 4B cannot be reduced.

In view of the above situation, the present invention provides a door weather strip provided with a door glass seal portion and a body seal portion, in which the width of the door weather strip is narrowed to widen the field of view from the door, and the area around the door frame is reduced. The task was to improve the appearance.

[0009]

According to the present invention, as shown in FIG. 2, a door weather strip 1 has a substantially U-shaped cross section and a flange holding portion 10 into which a flange 51 of a door frame 5 is inserted. The glass seal portion 1A and the body seal portion 1B are joined together to form an integral structure, and the flange holding portion 10 is attached to the flange 51 with the double-sided adhesive tape 8.

The flange holding portion 10 has a flange 51.
It is possible to adopt a structure in which the base portion 11 of the glass seal portion 1A and the base portion 16 of the body seal portion 1B are connected by their outer ends.

[0011]

Since the flange holding portion 10 is adhered to the flange 51 with the thin double-sided adhesive tape 8, the flange holding lip 33 (FIG. 4) is not required as in the conventional case, and the lip 3
Since it is not necessary to embed the cored bar 34 (FIG. 4) for giving the flange holding force to the flange 3, the wall of the flange holding portion 10 can be made thin. In addition to the fact that one wall of the flange holding portion 10 is formed by the base portion 11 of the glass seal portion 1A and the other wall is formed by the base portion 16 of the body seal portion 1B, the door weather strip without modifying the glass seal portion 1A. The width of 1 can be reduced.

[0012]
