Abstract

PURPOSE:To provide such sealing structure for an automobile as to reduce man-hours for assembling the automobile. CONSTITUTION:A door trim 3, which is installed in a door-inner-panel 2, is constituted from a core member 5 and a surface leather 7 made of a soft resin, which is adhered to this core member 5. The end part of this surface leather 7 is folded so as to form a parting seal 8 which makes close contact with a car-body opening edge 13. With this contrivance, the time for fitting the parting seal 8 to the door-inner-panel 2 can be saved.

Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a seal structure for an automobile door.

0002

[Prior Art] Conventionally, this type of seal structure has been developed by attaching a door trim to the inner panel of an automobile door, and arranging a weather strip and a parting seal on the edge of the door trim in close contact with the edge of the opening in the vehicle interior and exterior of the vehicle interior. It is known that the seal is double-sealed.

FIG. 2 shows the sealing structure of such a conventional automobile door (see FIG. 3), in which a weather strip 10 is attached to the end of the door inner panel 2 with a clip 1.
1, and a parting seal 20 is fixed to the door inner panel 2 outside the weather strip 10 with a clip 21, so that the weather strip 10 and the parting seal 20 are brought into close contact with the vehicle body opening edge 13. ing.

0004

In such a conventional automobile door seal structure, the weather strip 10 and the parting seal 20 double seal the vehicle body opening edge 1.
3, the sealing performance is good, but the problem is that it takes a lot of man-hours to attach the parting seal 20 to the door inner panel 2, which in turn increases the man-hours for assembling the automobile.

SUMMARY OF THE INVENTION An object of the present invention is to provide a seal structure for an automobile door that can reduce the number of steps required to assemble an automobile.

[0006]

[Means for Solving the Problems] That is, in the automobile door seal structure of the present invention, the door trim attached to the door inner panel is composed of a core material and a soft resin outer skin that is fixed to the core material, and the edges of this outer skin are The feature is that the parts are folded over to form a parting seal that fits closely to the edge of the vehicle body opening.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Examples of the present invention will be described below in detail with reference to the drawings.

FIG. 1 shows an embodiment of the present invention, and in this figure, 1 is a door. A door trim 3 is fixed to a door inner panel 2 of this door 1 with a clip 4. This door trim 3 consists of a core material 5 made of hard resin and a skin 7 made of soft resin with a sponge portion 6 integrally molded on the mating surface with the core material 5. It is formed larger by a predetermined amount. This door trim 3 has a parting seal 8 formed by folding the ends of the outer skin 7.

The door trim 3 is made by setting a core material 5 pre-formed into a predetermined shape and vacuum-formed material such as vinyl chloride into a foam mold, and then injecting urethane into the foam mold (sponge part 6
The core material 5 and the skin 7 are heated and pressurized in a mold to integrate them, and the parting seal 8 is also molded at the same time as the integral molding. . Then, the tip 9 of the skin 7 is adhered to the back surface of the core material 5.

Reference numeral 10 denotes a weather strip, and this weather strip 10 is fixed to the door trim 3 with a clip 11. Reference numeral 12 denotes a grommet that engages with the clip 4, and this grommet 12 is fitted into a mounting hole of the door inner panel 2.

The parting seal 8 and weather strip 10 attached to the door inner panel 2 in this manner are attached to the vehicle body opening edge 13 when the door 1 is closed.
The side wall 15 of the first step portion 14 and the side wall 17 of the second step portion 16 are in close contact with each other to prevent water from entering the inside of the vehicle from outside the vehicle.

As described above, in this embodiment, since the parting seal 8 is integrally molded in advance on the skin 7 attached to the door inner panel 2, there is no need to attach the parting seal 8 to the door inner panel 2 when assembling the automobile. It is possible to reduce the number of man-hours required to assemble the car.

The door trim 3 is made by molding the sponge portion 6 as described above, and setting the skin 7 with the parting seal 8 integrally molded on the end in a mold, and placing a hard resin inside the mold. The core material 5 may be integrated into the skin 7 by injecting the material. Furthermore, the door trim 3 has a core material 5 and a skin material 7.
The parting seal 8 may be manually molded after the parts are integrally molded into a predetermined shape.

[0014]

Effects of the Invention As explained above, the present invention comprises a door trim attached to a door inner panel consisting of a core material and a skin made of soft resin that is fixed to the core material. Since the parting seal is formed in close contact with the door, there is no need to clip the parting seal to the door inner panel when assembling the car.
The number of man-hours required for assembling a car can be reduced, and the production efficiency of cars can be improved.
