FIG. 9 is a cross-sectional view showing a configuration of a door trim for an automobile to which the present invention is applied, and FIG. 9 is a perspective view showing a configuration of still another embodiment of a resin core material used in the present invention.

Referring to FIG. 1, an automobile door trim 10 according to the present invention generally comprises a resin core 11 molded and pressed into a required shape and a skin 12 adhered to the surface of the resin core 11. The core 11 is made of a composite resin material in which talc is mixed with a polypropylene resin, and the skin 12 is a laminated sheet in which a polyethylene foam is laminated on the back of a PVC sheet in this embodiment. ing.

Further, the door trim 10 is formed with a waist flange portion 13 having a predetermined width for mounting the door inner seal 20, and in order to cooperate with the waist line of the instrument pad (not shown) for molding. On the front upper end side 10a of the door trim 10, the height of the waistline is set to be variable.

Therefore, since the height of the upper edge of the waist flange portion 13 for attaching the inner seal 20 is substantially constant, the height of the waist line and the height of the waist flange portion 13 on the front upper end side 10a of the door trim 10 are adjusted. Since the height position is different from the upper edge, a step portion 14 is formed.

The feature of the present invention lies in the configuration of the waist flange portion 13 formed on the resin core material 11.

That is, as shown in FIGS. 2 and 3, the notch 1 is formed in the waist flange portion 13 at the front upper end 10a where the height of the waist line of the door trim 10 is changed.

The door inner seal 20 may be supported and fixed by the following.

As described above, even if the resin core material 11 formed into a required shape by mold press molding is used, since the step is not formed on the mounting surface of the door inner seal 20 by the rib 16, the conventional spacer pad is not used. It can be abolished, and significant cost reduction can be expected due to the reduction in the number of parts and the number of installation steps.

Further, when the door inner seal 20 is attached to the waist flange portion 13 and the edges 16a, 16b of the rib 16, as shown in FIG.
Since the surface is covered with the skin material 12, the ribs 16 are not conspicuous to the outside, and if the skin material 12 is coated with an appropriate tensile force, there is no unevenness on the product surface of the door trim 10.

As a method for forming the ribs 16 on the resin core 11, as shown in FIG. 5, when the resin core 11 is molded between the core mold 30 and the cavity mold 31, By forming a groove (not shown), the rib 16 is formed.
May be integrally formed with the resin core material 11, and as shown in FIG. 6, a straight-up core 32 is set between a core mold 30 and a cavity mold 31, and the resin core is formed by the straight-up core 32. The rib 16 may be formed integrally with the material 11.

FIGS. 7 and 8 show another embodiment of the vehicle door trim 10 according to the present invention. In this embodiment, the waist flange of the resin core 11 is provided at the front upper end 10a of the door trim 10. FIG. The step 13 is provided with a step 17 in terms of a mold structure. The step 17 is provided with a plurality of ribs 18, and the upper edge 18 a of the rib 18 is formed at the upper end of the general waist flange 13. It is set at almost the same height position as the edge.

Therefore, the mounting portion for supporting the door inner seal 20 is set at substantially the same height position as the general waist flange portion 13 by the rib 18, so that the conventional spacer pad is eliminated, and As in the embodiment, the number of parts and the number of mounting steps can be reduced.

Further, in this embodiment, the notch 14
The rib 1 is formed on the waist flange 13 without forming
8, the door inner seal 20 does not meander, and the door inner seal 20 does not meander.
There is an effect that can be securely fixed.

FIG. 9 shows a third embodiment of the present invention. In this embodiment, a front upper end 10 of a door trim 10 is provided.
In a, the upper part 17 of the mold structure is set in the waist flange 13 of the resin core material 11 as in the second embodiment, but in this embodiment, instead of the rib 18,
This is a configuration in which a waist flange portion 19 is formed.

That is, the waist flange portions 13 and 19 are located on both sides of the step portion 17 and the upper end edges of both the waist flange portions 13 and 19 are at substantially the same height position. The door inner seal may be supported by the parts 13 and 19.
