Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial application field> The present invention mainly relates to improvement of a weather strip mounting structure in a center pillar of an automobile.

<Prior Art> This will be described with reference to FIGS. 4 to 6. FIG.

Conventionally, the mounting structure of the weatherstrip 8 for sealing between the door glass 6 and the center pillar 7 in an automobile is such that the base 8a of the weatherstrip 8 that makes the edge of the door glass 6 elastically contact the retainer 9 of the center pillar 7. In the hollow portion of the weatherstrip, there is provided a projection 8b which projects from the outer surface of the center pillar 7 and makes elastic contact therewith (see, for example, Japanese Utility Model Laid-Open No. 1-82920). However, the center pillar 7 of this weather strip 8
When the door glass 6 is closed and is elastically contacted with the weather strip 8, the weather strip 8 is bent as shown in FIG. There is a problem that the opening 10 occurs and the appearance is impaired.

In order to prevent the opening 10 of the weatherstrip, it is conceivable to restrain the protruding portion 8b to the center pillar 7. However, if the protruding portion 8b is restrained, the sealing property of the weatherstrip deteriorates. I will.

<Problem to be solved by the invention> From the above, as a weatherstrip mounting structure for the center pillar of an automobile, the structure is simple, and the seal is formed without opening the part that elastically contacts the center pillar. What is excellent is required.

It is an object of the present invention to provide a weather strip mounting structure for a center pillar of an automobile which has solved the above-mentioned problems.

<Means for Solving the Problems> A description will be given with reference to the drawings. To achieve the above objectives,
The weatherstrip mounting structure for the center pillar of the vehicle according to the present invention includes a base 3 supported by the center pillar 1 and a hollow portion 4 connected to the base 3 at an outer end Q of the base 3. A weatherstrip 2 is formed so as to face and protrude so as to cover the base portion 3, and a covering member 5 for covering the outer surface of the distal end of the hollow portion 4 with an extended portion thereof. 3 is attached to the center pillar 1 by overlapping attachment means 1c, and a thick portion 4d is formed in a portion of the hollow inner side wall 4c near the tip Q, and a step corner portion 4b is formed near the vehicle inner base end P of the thick portion 4d. When the door glass 6 is opened, the outer surface of the distal end of the hollow portion is formed as an arc-shaped outer surface 4f centered on the stepped corner portion 4b, and the inner surface 5b of the extending portion of the covering member 5 is circularly connected to the distal end of the hollow portion. Formed along the arcuate outer surface 4f and extended The surface 5b and the arcuate outer surface 4f are arranged close to each other, and when the door glass is closed, the hollow portion tip 4e is configured to swing and displace in the direction of the door glass with the stepped corner 4b as a fulcrum, and is also covered when the door glass is closed. The member 5 is configured to cover the tip 4e of the hollow portion.

<Operation> The weatherstrip mounting structure in the automobile center pillar configured as described above, when the door glass 6 is closed and elastically contacts the outer wall 4a of the hollow portion 4, as shown in FIG. The outer wall 4a is deformed and dented, and the inner wall 4c is bent at a thin portion near the step corner 4b, and the tip 4e of the hollow part swings toward the door glass 6 with the step corner 4b as a fulcrum. The strip 2 does not protrude from the covering member 5, and the clearance between the outer wall 4a of the hollow portion and the covering member 5 is made as small as possible, so that a flash surface can be achieved without deteriorating the appearance.

<Embodiment> An embodiment will be described with reference to FIGS. 1 to 4. Reference numeral 1 denotes a center pillar, 2 denotes a weatherstrip, and a base 3 of solid rubber in which a metal core 3a is embedded and a base 3 of the solid rubber. It consists of a hollow portion 4 connected to the vehicle inner base end P. The hollow portion 4 includes an outer wall 4a made of sponge rubber and an inner wall 4c made of solid rubber, and protrudes toward the outer end Q of the base portion 3 so as to cover the base portion 3. 5 is section T
The letter-shaped covering member 5a is a leg piece, and the leg piece 5a and the base 3 are superimposed on the outer surface of the center pillar 1, and the mounting means is provided.
Install with 1c.

4d is a thick portion formed near the tip of the inner wall 4c, 4b
Is a step corner formed near the vehicle inner base end P of the thick portion 4d, and is resiliently contacted to the base 3 so as to be able to come and go. The shape of the outer surface of the hollow portion 4 is formed on an arc-shaped outer surface 4f centered on the step corner 4b, and the inner surface 5b of the extending portion of the covering member 5 has a shape substantially along the arc-shaped outer surface when the door glass is opened. And the extended portion inner surface 5b and the arcuate outer surface 4f are arranged close to each other.

Next, the operation will be described. When the door glass 6 is opened, the arc-shaped outer surface 4f of the hollow portion 4 is formed into a smooth curved surface, the inner wall 4c is also substantially straight, and the thick portion 4d is formed on the outer end of the base portion 3 on the vehicle outside. The front end Q of the outer side wall 4a is deeply fitted in the inner surface 5b of the extending portion of the covering member 5, and the outer appearance of the weather strip 2 is well-aligned. When the door glass 6 is closed and brought into elastic contact with the outer wall 4a of the hollow portion 4,
As shown in FIG. 2, the outer wall 4a of the hollow portion 3 is pressed and dented,
In addition, the thin portion near the step corner 4b of the inner wall 4c is bent, whereby the front end 4e of the hollow portion swings toward the door glass 6 with the step corner 4b as a fulcrum. It does not protrude, hardly changes the appearance of the weatherstrip 2, and does not deteriorate the appearance.

<Effects of the Invention> The present invention divides the weatherstrip 2 into the base portion 3 and the hollow portion 4 as described above and independently configures them so that the cover member 5 can be attached to the center pillar 1. By avoiding the hollow portion 4 to the side in a state where the hollow portion 4 is overlapped with the base portion 3, the mounting can be easily performed by the mounting means 1c.

In addition, the swing of the front end 4e of the hollow portion of the weatherstrip 2 when the door glass 6 is closed is not hindered, and the clearance between the outer wall 4a of the hollow portion and the covering member 5 can be secured while ensuring a reliable seal. As small as possible, it is possible to effectively improve the appearance and make a flash surface.
