Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a weather strip which is mounted around a door opening of a vehicle body and seals the outer periphery of a door glass of a sashless door, and more particularly to a mounting structure thereof.

[0002]

2. Description of the Related Art As shown in FIG. 3, a hollow weather strip 4 for sealing the outer periphery of a door glass 3 is attached to an upper edge of a door opening of a vehicle body along a roof side 1 and a center pillar 2. . Conventionally, the weather strip 4 has been mounted by providing a retainer on the upper edge and the center pillar 2 and fitting it to the retainer.

Recently, it has been proposed to eliminate the retainer and adhere the weather strip 4 to the door opening edge 10 with the double-sided adhesive tape 7 as shown in FIG. 4 in order to reduce the cost and simplify the mounting. It is (actual Kaihei 1-112110
issue).

[0004]

By the way, a problem in the attachment with the double-sided adhesive tape is the positioning of the weather strip. That is, when the retainer is used, the weather strip is accurately positioned and fixed by the retainer without requiring special attention by the operator. However, when a long weatherstrip is adhered with a double-sided adhesive tape, even if the operator is careful, the weatherstrip may be partially displaced, and the weatherstrip may be attached in a meandering shape.

Therefore, a clip is also used, the clip is attached to the base of the weather strip at a predetermined interval, and the clip is pressed into a clip hole provided on the vehicle body side to position the weather strip. Means for adhering the base with double-sided adhesive tape can also be considered.

However, another problem in the case of using a clip together is that the clip head projects from the hollow inner surface of the base portion, so that the seal wall may come into contact with the clip head when pushed by the door glass. . Especially in weather strips along the roof side, if the door glass is displaced upward due to variations in the installation of the door glass, the seal wall is pushed up excessively by the door glass, and as a result, the seal wall is pressed against the clip head. To be If this is repeated, the seal wall may be damaged and the sealing performance may be deteriorated.

Therefore, the present invention is capable of further improving the sealing performance in a weatherstrip mounting structure using a double-sided adhesive tape together with a clip, without damaging the seal wall due to contact with the clip head. An object of the present invention is to provide a weather strip attachment structure that can be used.

[0008]

As shown in FIG. 1, the present invention forms a bridge 5 connecting a base portion 41 and a seal wall 42 in a hollow of a weather strip 4, and the bridge 5 is formed in the base portion 41. The section is Y-shaped with the side branching. And
At the position between the branch ends of the bridge 5 connected to the base 41, the base 4
1, a clip 6 is attached, the clip 6 is pushed into a clip hole 101 provided on the vehicle body 10 side to position the weather strip 4, and the base 41 is attached to the double-sided adhesive tape 7A, 7B.
The structure is such that it is adhered to the vehicle body 10. Adhesion is performed with two double-sided adhesive tapes on both sides of the clip 6, and the double-sided adhesive tape 7A on the vehicle body side is replaced with the double-sided adhesive tape 7B on the inside of the vehicle.
It is preferable to be softer and thicker than the above.

[0009]

Since the weather strip 4 is provided with the bridge 5, the waist of the seal wall 42 is strengthened and the seal wall 42 is not deformed irregularly when it is pushed in by the door glass 3, and the sealing performance is improved. Stabilize. Further, since the clip head 61 is covered with the bridge 5, even if the seal wall 42 is excessively pushed, the seal wall 42 is pushed through the bridge 5, so that no damage occurs.

The double-sided adhesive tapes 7A and 7B adhere to the weather strip 4 as well as the weather strip 4 and the vehicle body 10.
It plays a role of sealing between and. Since the sealing performance is mainly determined by the double-sided adhesive tape 7A on the outside of the vehicle, it is made softer and thicker than the double-sided adhesive tape 7B on the inside of the vehicle to improve conformability to irregularities on the mounting surface of the vehicle body 10 and is good. A good sealing property is secured.

Embodiment In the embodiment shown in FIG. 1, a roof side 1
A weather strip 4 is attached to the door opening edge 10 of the vehicle body along (FIG. 3).

The weather strip 4 has a base portion 41 composed of a base portion 411 and outer and inner side walls 412 and 413.
And the seal wall 42 connecting the tips of the side walls 412 and 413.
Is a hollow extruded body having a base portion 411 and an outer side wall 412 made of solid rubber and the other made of sponge rubber.

A bridge 5 connecting the seal wall 42 and the base 41 is formed in the hollow of the weather strip 4. The bridge 5 has a Y-shaped cross-section that branches off from the base 41 side, and one end thereof is connected to the seal wall 42 at a position inside the vehicle rather than a position pressed by the door glass 3. One of the branched other ends is a base 411 that is close to the root of the outer side wall 412.
The other is connected to the root of the inner side wall 413.

At the base portion 411 of the weather strip 4,
Clip holes 414 are provided at a predetermined interval between both connecting ends of the branched bridge 5. On the other hand, at the door opening edge 10 along the roof side 1 to which the weather strip 4 is attached, clip holes 101 are also provided at predetermined intervals.

To attach the weather strip 4, double-sided adhesive tapes 7A and 7B are attached to both sides of the clip hole 414 in the base portion 411 in the longitudinal direction in advance, and the clip 6 is inserted into each clip hole 414. Then, each clip 6 is press-fitted into the clip hole 101 of the door opening edge 10 to position the weather strip 4, and the double-sided adhesive tape 7
The weather strip 4 is attached by attaching the base portion 411 to the door opening edge 10 through A and 7B.

The double-sided adhesive tapes 7A and 7B are softer and thicker than the double-sided adhesive tape 7A on the outside of the vehicle. As a result, the double-sided adhesive tape 7A on the outer side of the vehicle is strongly pressed against the door opening edge 10 and deforms well following the irregularities of the seam or the like of the opening edge 10 so as to be in close contact therewith, thereby ensuring good sealing performance. The double-sided adhesive tape 7B on the inside of the vehicle secures the fixability of the weather strip 4 by making it relatively hard.

In the figure, 12 is a drip channel formed on the edge of the roof side 1, 13 is a molding attached to the drip channel 12, 43 is a door opening edge 10.
It is an opening trim attached to the flange 11 protruding from the inner back part of the.

According to the weatherstrip mounting structure of the present invention, however, the weatherstrip 4 is accurately positioned by clipping the double-sided adhesive tape 7 in place.
It is attached to the door opening edge 10 by A and 7B. In the present invention, the Y-shaped bridge 5 is provided in the hollow of the weather strip 4 so that the seal wall 42 is supported inside the pressing point of the door glass 3, so that the sealing performance around the door glass 3 is stable. In particular, according to the present invention, the clip head 61
Is surrounded by the branch portion of the bridge 5, so that even if the sealing wall 42 is pushed up excessively by the door glass 3 due to variations in the construction of the door glass 3, the sealing wall 42 is clipped via the bridge 5 The damage caused by being pressed against the portion 61 and directly rubbed against the clip head portion 61 does not occur.

FIG. 2 shows another embodiment of the present invention. In this embodiment, the weather strip 4 and the opening trim 43 are integrally formed by extrusion molding. A cored bar 44 is embedded in the opening trim 43. Both branch ends of the bridge 5 are connected to the base 411. The other structure is substantially the same as the previous embodiment.

In the present embodiment, when the weather strip 4 is mounted, the opening trim 43 is fitted into the flange 11 of the door opening edge 10 to temporarily position the weather strip 4. However, the fitting depth may partially vary, or the fitting depth may be partially tilted. Even in such a case, since the clip 6 is finally positioned, the attachment position of the weather strip 4 is not affected by the fitting state of the opening trim 43.

Although all the above embodiments relate to weather strips mounted along the roof side of the door opening edge, the present invention can also be applied to mounting weather strips along the center pillar.

[0022]

In the weatherstrip mounting structure of the present invention, the double-sided adhesive tape and the clip are used together, and the weatherstrip is positioned by the clip. Therefore, the weatherstrip can be adhered to an accurate position. it can. In the present invention, in particular, since a bridge for stabilizing the door glass sealing property is provided in the hollow of the weather strip and the clip head projecting into the hollow is covered with this bridge, the sealing wall is pushed by the door glass. When the seal wall is pressed, the seal wall is not directly pressed or rubbed against the clip head, and the durability of the seal wall is improved.
