A slit is formed on the upper surface of the armrest that bulges inward over the door trim, and a number of hook claws corresponding to the number of slits are provided on the lower surface of the base panel of the rest body to which the upper surface material such as padding and decorative material is attached. By inserting the hook claws into the slits, bending them, and caulking them, the rest body is integrally fixed to the armrest, and the outer end of the rest body is attached to the base of the atsupato trim. A technical measure has been taken to ensure that it can fit into the stepped portion and be crimped and attached without any gaps.

<Example> Next, an example of this invention will be described below based on the drawings.

1 is a door trim of an automobile, and FIG. 1 shows a partially disassembled state from the inside.

In the embodiment shown in FIGS. 1 and 2, the upper door trim 2 of the door trim 1 provided on the door inner panel has a soft body 4 of the pad on the inside of the metal panel 3, that is, on the passenger side, and a skin 5 thereof. A recessed portion 6 for inserting the arm is formed, and a stepped portion 7 of a set depth is formed outward at the base of the recessed portion 6 as shown in A.

The lower door trim 8 made of resin has a recess 6.
An armrest 9 is provided in the front-rear direction and is molded to bulge inward at the lower part of the armrest 9. A slit 1 is formed on the planar upper surface 10 of the armrest 9, which is inclined downward at a set angle.
A set number of 1, 11, etc. are drilled.

In the illustrated embodiment, as shown in FIG.
1 is provided on the upper surface of the convex portion formed on the upper surface 10, but it may also be provided directly on the upper surface 10.

On the other hand, 12 is a rest main body, and hook claws 1 are inserted into slits 11, 11, etc. by punching from a metal base panel 13 having a set shape.
4, 14... are bent downward in advance and protruded.

Then, a pad 15 made of urethane foam or the like is placed on the top surface of the panel 13, and a sheet 16 made of urethane resin as a skin material surrounds the top surface of the pad 15 to serve as a top surface material. The periphery of the edge is integrally wrapped around the base panel 13 to form a block.

In the above configuration, the atsupado door trim 2 is placed in a predetermined position.
After assembling and integrating the lower door trim 8 and the rest body 12, the outer end of the rest body 12 is attached to the atsupad door trim 2.
The hook claws 14, 14, . . . are inserted into the slits 11, 11, . . . in the upper surface 10 of the corresponding armrest 9.

In this process, a springback force is applied inward by the elasticity of the pad 15 disposed above the base plate 13 and the elasticity of the pad 4 of the recess 6, but the slits 11, 11, etc. act as stoppers and positioning is automatically performed. Moreover, the outer end of the rest main body 12 is connected to each hook claw 14 and each slit 1 within the stepped portion 7.
It can be pushed outward by the relative sliding of step 1, and is pressed against the stepped portion 7 without any gap.

In this state, 14, 14 protruding from the slits 11, 11... from the inside of the armrest 9 using an appropriate jig.
The rest main body 12 is assembled and fixed to the upper surface 10 of the armrest 9 by bending them laterally and caulking them.

Then, as each hook pawl 14 and each slit 11 engage with each other through relative sliding, the base panel 13 receives a wedge force that presses it against the upper door trim 2 side, so that the rest main body 12 Its base is pressed against the top trim 13, and it is assembled without any gaps, thereby preventing the intrusion of dust and the like.

In this case, since the stepped portion 7 is provided on the top trim 2, it is easy to insert the rest main body 12 into the stepped portion 7.

In this case, since the bending process of the hook claws 14, 14... can act to pull in the base panel 13 of the rest main body 12, the rest main body 12
are tightened and fixed more tightly.

Then, the outer end of the rest main body 12 is press-fitted to the stepped portion 7 of the recessed portion 6.

Further, in this case, the upper door trim 2 can be assembled to the lower door trim 8 after it is tightly connected to the rest main body 12.

Next, the embodiment shown in FIG. 3 is an embodiment in which the upper door trim 2 and the lower door trim 8 are entirely formed of a resin panel 3', and in this embodiment, the substantial operation and effect are the same as in the above-mentioned embodiment. do not have.

It goes without saying that the embodiments of this invention are not limited to the above-mentioned embodiments; for example, the lower door trim may be made of a metal panel, the slits and hook claws may be oriented vertically, and the rest body may be made of a metal panel. Various aspects can be adopted for the upper surface material, such as a soft pad or a decorative board made of wood grain attached to the outside of the skin.

<Effects of the invention> As described above, according to this invention, in the door trim structure of an automobile, the upper surface material of the rest body is attached to the upper surface of the armrest, which is formed in a shape that bulges inward from the upper trim to the lower door trim. By having a hook protruding from the bottom of the metal base panel, inserting it into a slit on the top of the armrest, bending it, and fixing it by caulking, it is basically possible to eliminate the need for screwing or tapping, and to easily attach parts. Not only does it have the excellent effect of simplifying the structure with fewer parts and processing, but it also has the advantage of being able to perform the work smoothly and reliably since all that is required is caulking when assembling. Ru.

Furthermore, since the rest is assembled by caulking the hook claws, the base panel is pulled in and brought into a tight state during the bending process of the hook claws, which has the excellent effect of further solidifying the fixation of the rest body.
