[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hollow seaming welt which is mounted on a center pillar body and elastically contacts a front end face of a rear door.

[0002]

2. Description of the Related Art A description will be given with reference to FIGS. 1
6 is a front side, 17 is a rear side, 18 is a vehicle inside, and 19 is a vehicle outside. Attached to the center pillar part body 10,
A hollow sponge rubber seal that elastically contacts the sash 21 of the rear door 20 at a U-shaped trim portion 40 that is fitted to a flange 11 protruding from the center pillar portion body 10 as a hollow seaming welt 80 that elastically contacts the front end surface of the rear door 20. A combination of the parts 90 is used.

However, since the hollow seal portion 90 uses a single sponge material, when the rear door 20 is closed, the hollow seal portion 90 is pulled and deformed by the sash 21 and attached to the vehicle interior of the sash 21. There is a problem that interference with the door weather strip 60 may occur, causing problems such as deterioration of the door closing force and breakage of the hollow seal portion 90. T is the traveling direction of the rear door 20. When the hollow seal portion 90 is deformed as shown in FIG. 3, the sash 21 can be seen from the inside of the vehicle as shown by an arrow B, and the sash 21 can be seen.
When the color is different from the color of the black rubber seaming welt 80 and the color of the black rubber glass channel 70, the sash 21 is painted black in order to cause an uncomfortable feeling and impair the appearance.

[0004]

When the rear door 20 is closed, the conventional seaming welt 80 is closed.
0 is deformed by being pushed by the sash 21, and may interfere with the door weather strip 60 attached to the inside of the vehicle of the sash 21, causing troubles such as deterioration of the door closing force and breakage of the hollow seal portion 90. If the sash 21 is not painted black, the color of the sash 21 can be seen from the interior of the vehicle, causing a sense of incongruity between the black seaming welt 30 and the black grass run channel 70 and impairing the appearance. It is necessary to paint.

[0005]

A description will be given with reference to FIGS. 1 and 4 to 6. The present invention is a seaming welt 30 in which a hollow seal portion 50 elastically contacting a sash 21 of a rear door 20 is connected to a U-shaped trim portion 40 fitted to a flange 11 protruding from a center pillar portion body 10. A glass run channel (70) fitted to the door sash 21 when the door is closed, wherein the thickness T of the rear portion 51 on the vehicle interior side of the hollow seal portion 50 is larger than the thickness t of the other portion 52 of the hollow seal portion. And the rear portion (51) of the hollow seal (50) inside the vehicle cover the sash 21.

[0006]

EXAMPLE An example will be described. 16 is the front side, 17
Is the rear side, 18 is the inside of the vehicle, 19 is the outside of the vehicle, 10 is the center pillar body, 11 is the center pillar body 1
0, a flange protruding outside the vehicle, 20 is a rear door, 21
Is a sash attached to the rear door 20; 30 is a seaming welt;
It comprises a character-shaped trim portion 40 and a hollow seal portion 50 elastically in contact with the sash 21. T is the traveling direction of the rear door 20. Reference numeral 41 denotes a core bar embedded in the trim portion 40, reference numeral 60 denotes a door weather strip elastically contacting the center pillar portion body 10 and the hollow seal portion 50 which are fitted to the inside of the sash 21, and reference numeral 70 denotes a sash 21 vehicle. It is a glass run channel fitted on the outside. Further, in the present invention, in particular, the rear portion 5 of the hollow seal portion 50 on the vehicle interior side is used.
1 is made thicker than the thickness t of the other portion 52 of the hollow seal portion to increase the rigidity, so that the rear door 20
Is closed, the amount of deformation is small even when the hollow seal portion 50 is pulled by the sash 21, so that the hollow seal portion 50 does not interfere with the door weather strip 60 attached to the inside of the sash 21, and the sash 21 is removed from the inside of the vehicle. It is hidden from view.

The operation will be described below.
The stiffness of one is greater than the stiffness of the other part 52,
When the rear door is closed, it is pushed or pulled by the sash 21 that enters when the rear door is closed.
Even if is deformed, it does not flow to the inside of the vehicle, and therefore does not interfere with the door weather strip 60, and does not cause problems such as deterioration of the door closing force and breakage of the hollow seal portion 90. Also, even if the sash 21 is not painted black, the other parts 52 do not turn up and the sash 21 is not exposed, and the appearance is always neat and the sash 21 is painted black. do not have to.

[0008]

[Effect of the Invention] Since the present invention is configured as described above,
When the rear door 20 is closed, the door weather strip 60
And the other parts 52 of the hollow seal part 50 are turned up and the sash 21 is exposed. No, the appearance is always clean,
It is not necessary to paint the sash 21 in black, and this has the effect of improving the door closing force, improving the appearance, and reducing the painting cost.
