Abstract

PURPOSE:To increase adhesiveness of an weather strip to the edges of door glasses on which the weather strip is pressed and also increasing attractiveness, in a weather strip mounted along a center pillar of an automobile. CONSTITUTION:A solid rubber layer 5 is formed on the internal surface of a corner portion 47 which connects a side wall 42 of an weather strip comprising sponge rubber to a seal wall 44 on which the edges of door glasses 3A and 3B are pressed. Thus a clearance a produced between the end surface of the door glasses 3A and 3B and the seal wall 44 of the weather strips 4A and 4B can be reduced, and the sealing property and attractiveness can be increased.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a weatherstrip for an automobile, and more particularly to a weatherstrip attached along a center pillar of a hardtop type automobile.

[0002]

2. Description of the Related Art Generally, in a hard top type automobile having a center pillar 1 as shown in FIG. 4, a weather strip is attached along the center pillar 1, and when the door is closed, a rear end of a front door glass 3A is attached to each weather strip. The edge and the front edge of the rear door glass 3B are pressed.

FIG. 5 shows a conventional structure of a weather strip, in which a partition wall 21 having a tip forming a pillar molding projects toward the vehicle exterior direction at the center of a retainer 2 provided on the outer surface of a center pillar 1. Weather strips 4A and 4B are attached to the front side and the rear side of the retainer 2 with the partition wall 21 interposed therebetween. The weather strips 4A, 4B are hollow bodies made of sponge rubber, and the edges of the door glasses 3A, 3B are pressed against these sealing walls 44.

[0004]

By the way, the door glass 3A, 3B is attached to the seal wall 44 of the weather strip 4A, 4B.
When the edge of the door is pressed, a V-shaped gap a in which the opening spreads between the edge of the door glass 3A, 3B and the seal wall 44 is formed.
Occurs. For this reason, water leakage may occur at the time of car washing with high-pressure car wash water, and the door glass 3
The end faces of A and 3B appear in the appearance, and the appearance is not good.

Therefore, the present invention has been made in order to improve the sealability and the appearance of the weather strip along the center pillar by narrowing the gap a as much as possible.

[0006]

The present invention is shown in FIGS. 1 and 2.
As illustrated in FIG. 2, the hollow weather strips 4A and 4B made of sponge rubber are connected to the side wall 42 along the partition wall 21 of the retainer 2 and the seal wall 44 against which the edges of the door glasses 3A and 3B are pressed. The solid rubber layer 5 is formed on the inner surface side of the corner portion 47. The solid rubber layer 5 is formed so as to extend in a range that does not reach the pressing portion by the edges of the door glasses 3A and 3B. In addition to the solid rubber layer 5 of the corner portion 47, the portion that engages with the tip end portion of the partition wall 21 forming a pillar molding may be formed of solid rubber.

[0007]

When pressed by the edges of the door glasses 3A and 3B, the corner portion 47 of the seal wall 44 is supported by the solid rubber layer 5 from the inside and is not deformed.
Is bent and pushed in at a position closer to the pressing side than the solid rubber layer 5, the gap a between the end edges of the door glasses 3A and 3B and the seal wall 44 becomes extremely narrow.

[0008]

1 and 2 show a first embodiment of the present invention. As shown in FIG. 1, the outer surface of the center pillar 1 has a mountain-shaped cross-section with the center protruding, and a retainer 2 is attached so as to cover the outer surface. A partition wall 21 projects from the center of the retainer 2, and the tip of the partition wall 21 forms a pillar molding.

Weather strips 4A and 4B are fitted on the front side and the rear side of the retainer 2, respectively.
The weather strips 4A and 4B have substantially the same structure,
Base portion 41 and side walls 42, 43 extending from both ends of the base portion 41
And a seal wall 44 connecting the side walls 42 and 43, and a bridge 45 connecting the central portion of the seal wall 44 and the base 41, forming a hollow body as a whole. And base 4
1 is fitted to the retainer 2, and the side wall 42 is in close contact with the end side surface of the partition wall 21 forming the pillar molding. Side wall 4
2 and the seal wall 44 are connected by a rounded corner portion 47. Side wall 42 that tightly engages the end of the partition wall 21
The base end side is formed of solid rubber, and the inner surface side of the subsequent corner portion 47 is formed of solid rubber layer 5. The tip of the solid rubber layer 5 is gradually thinned, and the tip position is closer to the side wall 42 than the pressing point of the door glasses 3A and 3B (FIG. 2). The other parts of the weather strips 4A and 4B are made of sponge rubber, and the weather strips 4A and 4B are made of solid rubber material.
It is manufactured by integrally extruding a sponge rubber material.

The weather strip 4 constructed as described above
In A and B, when the edges of the door glasses 3A and 3B are pressed against the seal wall 44 when the door is closed as shown in FIG. 2, the corner portion 47 is supported by the solid rubber layer 5 from the inner surface and is not deformed. The wall 44 is a solid rubber layer 5
Is bent and pushed in at the front end side, that is, at a position close to the pressing point. Therefore, the end surfaces of the door glasses 3A and 3B and the surface of the seal wall 44 facing the door glasses 3A and 3B are close to each other and parallel to each other, and the opening of the gap a is small and the contact area between them is wide. . Therefore, sufficient sealing performance is ensured when washing the car with high-pressure car wash water. Further, the end surfaces of the door glasses 3A and 3B are hard to see from the outside, and the outer surfaces of the door glasses 3A and 3B and the outer surface of the corner portion 47 are flush with each other with a slight clearance opening, so that the appearance is significantly improved.

FIG. 3 shows a second embodiment of the present invention. In this embodiment, a weather strip 4 made of sponge rubber is used.
A and 4B are connected by solid rubber at these corners 47 to form an integral structure. That is, the central portion 51 of the solid rubber having a hat-shaped cross section has the outer surface serving as a pillar molding, and the both end portions have both weather strips 4.
Solid rubber layer 5 along the inner surface of the corner portion 47 of A and 4B
Is formed. Other structures are substantially the same as those of the first embodiment, and corresponding parts are designated by the same reference numerals. This embodiment is also the first
The same effects and advantages as the embodiment of

[0012]

As described above, when the weather strip of the present invention is pressed by the door glass, it deforms so as to wrap the pressing end, and has a good sealing property and the door The appearance around the glass can be improved.
