Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a weather strip that is attached along the edge of an opening in an automobile body and that forms a seal by contacting a mating member such as a door or trunk lid that opens and closes the opening. It is something.

[Prior art]

A weather strip W is attached to an opening edge of an automobile body, for example, an opening edge of a trunk room 5 shown in FIG. 7, and comes into contact with the inner surface of the outer circumference of a trunk lid 6 to perform a sealing action.

As shown in FIG. 4, the weather strip W includes a garnish part 1 having an inverted U-shaped cross section and a retaining lip 11 on the inner facing surface, and a hollow seal part formed at the top of the garnish part 1 and in contact with the trunk lid 6. 2, and a seal lip 3 protruding from the side surface of the garnish part 1.

The garnish part 1 is generally made of solid rubber, and a reinforcing insert 4 is embedded therein. The seal lip 3 is formed on the side surface facing the outside of the vehicle when the weather strip is attached, extends diagonally downward, and has a tip made of sponge rubber.

As shown in FIG. 5, this weather strip is attached to the vehicle body by inserting into the garnish portion 1 a flange 70 that rises from the edge of the trunk lid opening. The seal lip 3 is then pressed against the vehicle body surface.

[Problems that this invention attempts to solve]

By the way, at the four corners of the trunk lid opening edge, the weather strip is bent at a nearly right angle with the outer diameter of the side surface on which the seal lip 3 is formed, so that the entire seal lip that faces diagonally downward is pulled toward the garnish part 1 and its tip is bent downward. It starts to turn towards. Therefore, at the corner portion, the tip of the seal lip 3 is pressed against the vehicle body surface 7 from a direction substantially perpendicular to the vehicle body surface 7, so that the tip may be rolled toward the interior of the vehicle as shown in FIG.

If such entrainment occurs, the sealing performance will deteriorate. In addition, if the weather strip is rolled in, the weather strip becomes slanted and looks bad, and the upper end of the weather strip is higher at the corner area than at the part attached to the linear opening edge shown in Figure 5, which reduces the closing force of the trunk lid. There is a problem in that the amount increases.

Therefore, the present invention aims to improve the seal lip 3 of the weather strip and solve the above-mentioned conventional problems.

[Means for solving problems]

As shown in FIG. 1, the present invention is characterized in that the seal lip 3 of the weather strip is formed into an inverted V shape that rises obliquely upward from its base, is inverted, and extends downward.

[Function and effect]

When the weather strip is bent to be attached to the corner of the car body opening, the seal lip 3 is attracted to the garnish part 1 as shown in FIG. 3, but the angle of the tip part that contacts the car body surface 7 with respect to the car body surface 7 hardly changes. Therefore, the entrainment that occurs in the conventional case does not occur.

Therefore, the sealing performance is maintained in the same manner as in the straight portion of the vehicle body opening. Furthermore, there is no problem of an increase in the opening force of the trunk lid due to the inclination of the weather strip or changes in height.

〔Example〕

1 to 3 show embodiments of the present invention, and the differences from conventional weather strips will be mainly explained.

A seal lip 3 is formed at the lower end of one side of the garnish part 1. The seal lip 3 rises obliquely upward from the lower end, and extends downward in a substantially inverted V shape. The tip that inverts and extends downward is made of sponge rubber.

The other structure is substantially the same as the conventional weather strip described above, with a reinforcing insert 4 embedded in the garnish portion 1, and retaining lips 11 formed in opposing directions inside. A hollow seal part 2 is formed at the top of the garnish part 1. The seal part 2 is made of sponge rubber, and of the four holding lips 11, the seal lip 3
The retaining lip at the lower end of the side is made of sponge rubber from the bottom to the tip. This weather strip is formed by extrusion molding.

FIG. 2 shows the state in which the flange 70 rising up from the edge of the trunk opening, particularly the straight portion thereof, is attached, and the tip of the seal lip 3 is pressed against the surface 7 of the vehicle body.

FIG. 3 shows how the flange 70 is attached to the corner portion. At the corner portion, the weather strip is bent with the side surface on which the seal lip 3 is formed as the outer diameter surface, so that the top of the seal lip 3 is drawn toward the garnish portion 1.

However, the angle of the tip of the sponge rubber hardly changes, and it is pressed against the vehicle body surface in almost the same state as the part shown in FIG.

Therefore, the sealing performance of the seal lip 3 does not deteriorate at the corner portions. Further, the weather strip does not slope at the corner portion and its upper end does not become higher than at the straight portion, and the problem of increased closing force of the trunk lid does not occur.
