Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to a weather strip having a structure in which a cover lip is provided on one side of a U-shaped gripping portion with a downward opening, and a covered member is inserted and assembled from directly above the cover lip.

As this type of weather strip, a back door weather strip is used for the purpose of sealing between the vehicle body sheet metal 1 and the back door 2, as shown in FIG. 2, in a liftback style passenger car as shown in FIG. There is a strip (hereinafter referred to as weather strip) 3.

This weather strip 3 is applied to the vehicle body sheet metal before assembling the quarter trim (covered part) 5, etc. that make up the interior of the language room, in order to prevent damage to the paint film on the back door 2 and its surroundings and to ensure work safety. It is assembled to the mounting flange 6 of.

At this time, the quarter trim 5 needs to be assembled under the cover lip 8 that projects diagonally downward from one side of the U-shaped grip 7, and is assembled in a floating position as shown in FIG.
If left as is, there will be a problem with sealing performance, so a post-work of pushing in the weather strip 3 will be required.

Note that when the weather strip is completely assembled from the beginning, the cover lip 8 is wedged between the quarter trim 5 and the U-shaped grip 7, as shown in FIG. 4, and the upper end of the quarter trim 5 is exposed and the cover lip cannot perform the function of

In view of the above, the object of this invention is to provide a weather strip that does not require the weather strip to be lifted up when assembling the cover member from directly above the cover lip, and in which the cover lip does not get caught. .

The gist of this invention is to provide a weather strip with a cover lip on one side of a U-shaped grip with a downward opening, and a covered member inserted from above the cover lip to be assembled. A lever lip that bends with the base as a fulcrum upon insertion of the covered member is provided diagonally downwardly, and a cover lip is provided above the base of the lever lip at a required angle to protrude, and the protrusion of the cover lip is This weatherstrip has a length smaller than the length from the lower side of the cover lip protrusion of the lever lip.

An embodiment of this invention will be described below with reference to figures.

As shown in FIG. 5, a lever lip 13 is protruded diagonally downward from one side of the U-shaped grip part 12 of the lower opening of the weather strip 11, and a cover lip 15 is attached at a required angle (example) above the base of the lever lip 130. 90°).

At this time, the lever lip 13 may have a thick tip so that the bending fulcrum is located at the base, that is, at the protruding position of the cover lip 15.

Further, the protrusion length 11 of the cover lip 15 is smaller than the protrusion length 12 of the lever lip 13 from the lower side of the cover lip protrusion.

At this time, the larger the difference a is, the better the workability of assembling the quarter trim 5 will be.

Further, it is desirable that the cover lip 15 be made of sponge rubber so that the quarter trim 5 may sometimes get caught when assembled.

In the illustrated example, 16 is an insert, 17 is a hollow seal portion, 18 is a seal lip, and 19.20 is a grip lip.

Further, this weather strip 11 is molded from a comb material or the like by a well-known extrusion method.

Next, how to use the above embodiment will be explained.

After the Unisa strip 11 is completely assembled without floating on the mounting flange 6, the quarter trim 5 is inserted from above the cover lip 15 as shown in FIG. As shown in FIG. 6, the lever lip 13 is pressed against the side wall of the U-shaped grip 12, and the cover lip 15 is sandwiched between the lever lip 13 and the quarter trim 5 and extended downward.

Immediately before the next assembly is completed, as shown in FIG. 7, the cover lip 15 rises slightly above the upper end of the quarter trim 5 due to its repulsive force.

At this time, the protruding length 11 of the cover lip 15 is smaller than the protruding length 12 of the lever lip 13 from the lower side of the cover lip protruding source.

Therefore, when the final assembly is completed, the cover lip 15 is removed from the upper end of the quarter trim 5, as shown in FIG. 8, and covers the upper end of the quarter trim 5 so as not to be exposed.

At this time, since the lever lip 13 is bent downward using the base as a fulcrum, the cover lip 15 rotates downward in conjunction with the lever lip 13 to provide a sufficient covering effect.

Since the weather strip of this invention has the above-mentioned configuration, when the covered member is inserted from above the cover lip and assembled, there is no need to float the weather strip in advance and assemble it to the mounting flange, and the cover lip is There is no risk of jamming, and work efficiency is greatly improved when assembling the covered part (quarter trim).
