Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automobile door in which a door glass weather strip is attached along a belt line, and more particularly to a contact pressure adjusting structure for a door glass weather strip and a door glass in a full trim automobile door. It is about.

[0002]

2. Description of the Related Art Door glass weather strips 1 and 2 (hereinafter, simply referred to as weather strips) are attached to an automobile door along a belt line as shown in FIGS. The weather strips 1 and 2 include a door trim 5 that covers the door outer panel 3 and the door inner panel 4.
And the door glass 6 are sandwiched between the weather strips 1 and 2 to prevent water droplets, dust, and the like from entering the interior of the door.

[0003]

However, the upper end portions of the door outer panel 3 and the door inner panel 4 have open cross sections because the door glass 6 needs to be taken in and out.
It cannot be said that the rigidity is sufficient. In particular, the rigidity around the central portion in the front-rear direction tends to be insufficient. Therefore, when the door glass 6 bends outward, the door outer panel 3 side is pushed outward and the gap a between the openings increases, and a gap is created between the door glass 6 and the inner side weather strip 2 to cool the room. May invade. On the contrary, when the door glass 6 bends inward, a gap is created between the door glass 6 and the outer side weather strip 1 to cause unwiping of water drops and the like. If the interval a is set to be sufficiently small, it is possible to eliminate the sealing failure such as invasion of cold air or unwiping, but the contact pressure between the weather strips 1 and 2 and the door glass 6 becomes too high, and the door glass 6 moves up and down. Therefore, there is a problem that the operation force when the regulator 7 is operated becomes excessive.

Therefore, an object of the present invention is to provide an adjusting structure for a vehicle door glass weatherstrip, which can easily set the contact pressure between the door glass and the weatherstrip within a reference range and exhibit good sealing performance. To do.

[0005]

In order to achieve the above object, the present invention has a vertical wall portion formed at the upper end portion of a door inner panel, and a door inner portion formed at the upper end portion of a door trim that covers the indoor side surface of the door inner panel. Forming a mounting flange that covers the outside of the vertical wall portion of the panel and hangs downward, in an automobile door in which a door glass weather strip is mounted on the outer surface of this mounting flange, on the inner surface of the mounting flange of the door trim, A plurality of ribs whose tops contact the outer surface of the vertical wall portion of the door inner panel are provided at appropriate intervals in the vehicle front-rear direction, and the contact pressure between the door glass weather strip and the door glass can be adjusted by the height of the ribs. It was done.

If the height of the rib formed on the inner surface of the mounting flange of the door trim is increased, the inner side weather strip is strongly pressed against the door glass, so that the contact pressure is increased and conversely the rib height is increased. The lower the pressure, the lower the contact pressure. Therefore, by adjusting the height of the rib,
The contact pressure can be adjusted arbitrarily.

The rigidity of the upper and lower portions of the door outer panel and the door inner panel, especially near the central portion in the front-rear direction, tends to be insufficient. However, in consideration of this insufficient rigidity, the height of the rib near the central portion in the front-rear direction is increased. With this, the contact pressure between the weather strip and the door glass can be made substantially uniform in the front-rear direction.

[0008]

3 to 5 show a first embodiment of a vehicle door having a full trim structure according to the present invention. In the figure, 10 is an outer panel of a vehicle door, 11 is an inner panel, and a gap that forms an opening for raising and lowering a door glass 12 is provided at the upper ends of the outer panel 10 and the inner panel 11. Outer panel 1 facing this gap
A vertical wall portion 10a that hangs downward is bent and formed at the upper end portion of 0, and an outer weather strip 13 is attached to the vertical wall portion 10a by adhesion or the like. Further, a vertical wall portion 11a that hangs downward is also bent and formed at the upper end portion of the inner panel 11 that faces the gap.

A door trim 14 made of a soft resin covers the entire inner surface of the inner panel 11 on the indoor side.
A mounting flange 14a is integrally formed at the upper end of the inner panel 11 so as to cover the outer surface of the vertical wall 11a of the inner panel 11 and hang downward. A retainer 15 is attached to the outer surface of the mounting flange 14a by caulking, bonding, etc.
The base of the weather strip 16 on the inner side is fixed to the retainer 15.

On the inner surface of the mounting flange 14a of the door trim 14, as shown in FIG. 5, a plurality of ribs 14b whose top contacts the outer surface of the vertical wall portion 11a of the inner panel 11 are provided at appropriate intervals in the front-rear direction of the vehicle body. Has been. The clearance b between the mounting flange 14a and the vertical wall portion 11a can be adjusted by the height of the rib 14b, and therefore the weather strip 16
The contact pressure between the door glass 12 and the door glass 12 can be adjusted. In addition,
The spacing C between the adjacent ribs 14b is set to such an extent that the mounting flange 14a portion between the ribs 14b is not bent by the reaction force of the weather strip 16. The rib 14
The interval b of b does not have to be constant and may be changed arbitrarily. Generally, since the center portion of the door glass 12 tends to bend toward the outside of the vehicle, the rib 14 at the center portion in the front-rear direction is
It is desirable to set b to be slightly higher than the ribs 14b at the front and rear ends.

Next, a method of adjusting the contact pressure between the weather strips 13 and 16 and the door glass 12 will be described. First, an automobile door having the above structure was prototyped, and the door glass 12
Raise and lower to inspect whether a seal defect has occurred and whether the operating force of the regulator is appropriate. That is,
It is inspected whether cold air has penetrated into the room, whether or not water drops or the like have been left unwound, and whether the door glass 12 can be smoothly moved up and down. If a seal failure occurs, the door trim 14 is adjusted so that the rib 14b in the seal failure portion of the ribs 14b arranged in the front-rear direction becomes high.
To adjust. As a result, the weather strip 16 on the inner side is pressed against the door glass 12 and the defective seal is eliminated. Further, when the lifting operation force of the door glass 12 is excessive, the height of the rib 14b may be reduced as a whole. If the sealing defect is eliminated by the adjustment work, the final shape of the door trim 14 may be determined according to the shape of the rib 14b. In this way, the shape of the inner panel 11, the outer panel 10, the weather strips 13 and 16 is not changed at all, and the height of the ribs 14b of the door trim 14 is simply adjusted to eliminate the defective seal, thereby significantly reducing the manufacturing cost. Can be reduced to

A curved door glass may be used as the door glass 12. In this case, as the door glass 12 is moved up and down, the door glass 12 and the weather strip 13,
The contact pressure with 16 may change, resulting in poor sealing. To solve this problem, the vertical wall portions 10a and 11a of the outer panel 10 and the inner panel 11 are attached to the door glass 1.
It is necessary to accurately process the curved surface shape to correspond to the second curved surface, but this work is practically difficult. However, in the present invention, the mounting flange 14a of the door trim 14 can be freely curved in accordance with the curved surface of the door glass 12 by arbitrarily changing the height of the rib 14b of the door trim 14, and the sealing failure can be eliminated. Outer panel 1 at this time
0 and the vertical wall portions 10a, 11a of the inner panel 11 do not require high dimensional accuracy, so that the manufacturing is simplified.

In the above embodiment, the inner panel 11 is used.
Although the case where the vertical wall portion 11a hangs downward is shown, the present invention can be applied even when the vertical wall portion 11a stands upright.

[0014]

As is apparent from the above description, according to the present invention, the contact pressure between the weather strip and the door glass is adjusted by the height of the rib formed on the inner surface of the mounting flange of the door trim. Therefore, without changing the shapes of the door inner panel, the door outer panel, the weather strip, and the like, the contact pressure can be easily adjusted to an appropriate value, and good sealing performance can be exhibited.
