Description

The present invention relates to an automotive weather strip that is attached to the periphery of a vehicle body opening of a vehicle body and seals between the periphery of the vehicle body opening and the substantially upper half of the opening opening / closing member. More particularly, the present invention relates to an automobile weather strip having a trim portion attached to a flange portion formed on a periphery of a vehicle body opening portion or an opening portion opening / closing member, and a seal portion that contacts and seals the opening portion opening / closing member or the vehicle body opening portion periphery It is.
The present invention will be described by taking, as an example, an opening trim weather strip that is attached to substantially the upper half of the flange at the periphery of the vehicle body opening, contacts the door when the automobile door is closed, and seals between the door and the vehicle body.

As shown in FIG. 6, the opening trim weather strip 110 attached to the vehicle body opening peripheral edge 6 of the automobile body is formed by extrusion molding, and a single member is connected by a mold forming portion 111 to form an annular shape. And attached to the periphery 6 of the vehicle body opening.
As shown in FIG. 7, the cross-sectional shape includes a trim portion 120, a cover lip 130, and a hollow seal portion 140.

  The trim portion 120 has a substantially U-shaped cross section, and holds the flange portion 7 formed on the periphery 6 of the vehicle body opening, and attaches the opening trim weather strip 110 over the entire periphery of the vehicle body opening. In the trim portion 120, a metal insert member 126 is embedded in order to reinforce the force for holding the flange portion 7 therein, and a vehicle outer side holding lip 124 for holding the flange portion 7 on the inner surface of the substantially U-shaped cross section. A vehicle inner side holding lip 125 is formed and held by the flange portion 7 of the vehicle body 1 by the holding lips 124 and 125.

In recent years, there has been a strong demand for weight reduction of automobiles, and it has become necessary to eliminate the metal insert member 126.
Further, when the opening trim weather strip 110 is attached to the corner of the opening / closing member or the periphery of the vehicle body opening, the hollow seal portion 140 is buckled or bent when it is bent along the corner. In order to prevent returning to the linear direction, the corner portion is also formed by molding. However, in this case, two steps of extrusion molding and mold forming are required, which takes time and increases the cost.

Therefore, as shown in FIG. 8, a weather strip 210 is proposed in which an insert member is not embedded in the trim portion 220 (see, for example, Patent Document 1).
The weather strip 210 of FIG. 8 engages the trim portion 220 with the flange portion 7 only by engaging the holding protrusion 226 formed on the inner surface of the trim portion 220 with the folded portion of the sheet metal of the flange portion 7. The power to do was not enough.

As shown in FIG. 9, a weather strip 310 is proposed in which an insert member is not embedded in the trim portion 320 as in FIG. 8 (see, for example, Patent Document 2).
The weather strip 310 of FIG. 9 is attached to the flange portion 7 by adhering a double-sided adhesive tape 321 attached to one inner surface of the trim portion 320 to the side surface of the flange portion 7. Further, a locking projection 322 is formed on the other inner surface of the trim portion 320 and is engaged with the projection 7 c of the flange portion 7. In this case, since the double-sided adhesive tape 321 is attached, labor and cost increase.

Furthermore, as shown in FIG. 10, a weather strip 410 in which an insert member is not embedded in the trim portion 420 is proposed as in FIG. 8 (see, for example, Patent Document 3).
The weather strip 410 shown in FIG. 10 is bent into a U-shaped cross section to form the tip portion of the flange portion 7, and one side wall 422 of the trim portion 420 is inserted into the U-shaped cross section, and the flange portion 7 is bent. The tip is inserted between the side wall 422 and the side wall 423. In this case, it takes time to fit the trim portion 420 into the flange portion 7 when the weather strip 410 is mounted, and the shape of the flange portion 7 becomes complicated.

  Further, as shown in FIG. 11, in order to attach a weather strip that does not embed an insert member, it is proposed that a cut and raised portion 7d is provided in the flange portion 7 and the trim portion is locked to the cut and raised portion 7d. (For example, refer to Patent Document 4). In this case, however, the trim portion of the weather strip has only a groove for inserting the flange portion 7 at the center, and the holding force of the trim portion is not sufficient.
