Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automobile trim, and more particularly to an automobile trim whose trim main body is formed by vacuum forming.

[0002]

2. Description of the Related Art Automobile trims, such as door trims, include:
Clip seats are provided at appropriate intervals along the front and rear edges and the lower edge of the rear surface of the trim body. The clip seat is for engaging a clip for connecting and fixing the trim to a vehicle frame. Conventionally, the clip seat is injection-molded separately from the trim main body and separately for each corresponding clip, and then adhesively fixed to the trim main body. This is because if the clip seat is formed integrally with the trim main body by vacuum forming, the clip seat portion will be seen to be depressed from the interior of the automobile, which impairs aesthetic appearance.

[0003]

In the above-mentioned conventional construction, since the clip seat is formed as a single unit for each clip, a large number of clip seats are attached to one automobile trim while positioning one by one. Need
There was a problem that it took time.

[0004]

In order to solve the above-mentioned problems, the present invention comprises a trim main body and a plurality of clip seats provided on the back surface of the trim main body, and is engaged with these clip seats. In a vehicle trim in which the trim main body is connected to a vehicle frame via a clip, a backing plate is joined to a back surface of the trim main body, and the plurality of clip seats are integrally formed on the backing plate. It is characterized by the following.

When the vehicle trim is a door trim, the backing plates are joined to the front and rear end edges and the lower end edge of the rear surface of the trim body of the door trim along the longitudinal direction of these edges, respectively. The plate may be integrally formed with the plurality of clip seats at intervals in the longitudinal direction.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below in detail with reference to FIGS. FIG. 1 shows a door trim 10 of an automobile. This door trim 10
A substantially rectangular flat plate-shaped trim main body 11, an upper reinforcement 20 joined to the upper rear edge of the trim main body 11, and each edge of the rear surface of the trim main body 11 excluding the upper edge, that is, a front edge ( In the figure, a left edge, a rear edge (right in the same figure), and a reinforcement 30 (backing plate) joined to the lower edge, respectively. These trim body 11 and upper reinforcement 2
Each of the reference numeral 0 and the reinforcement 30 is a vacuum molded product made of a polypropylene sheet having a thickness of about 3 mm.

Although not shown, a weatherstrip mounting seat is provided at an upper end of the upper reinforcement 20, and a weatherstrip for a door window is attached to the weatherstrip mounting seat.

The reinforcement 30 is formed in a long plate shape, and its length in the longitudinal direction extends substantially the entire length of the front edge, the rear edge or the lower edge of the trim main body 11, respectively. The reinforcement 30 includes a clip 40 described later.
Is integrally formed with the clip seat 31 for engaging with the clip seat. Clip seat 31 is 3 per one reinforcement 30
The clip seats 31 are arranged at appropriate intervals from each other in the longitudinal direction of the reinforcement 30.

The clip seat 31 is formed by raising a part of the reinforce 30 toward the surface thereof (lower in FIG. 2 and upper in FIG. 3) during vacuum forming of the reinforce 30. As shown in FIG.
The shape 1 is a covered cylindrical shape having a cover surface 32.

A hole 33 is formed in the cover surface 32. The hole 33 is formed in a daruma shape by connecting a large hole portion 33a and a small hole portion 33b having different diameters with a communication portion 33c. The diameter of the large hole portion 33a is larger than the diameter of the head portion 40a of the clip 40 described later,
The diameter of b is smaller than that. The communication part 3
The width of 3c is slightly smaller than the thickness of the neck 40b of the clip 40 described later.

By the way, the upper reinforcement 20
Is not provided with such a clip seat. A door window is housed inside the door trim 10 and the door frame, and the door window is attached to the door trim 1.
This is because it is necessary to ascend and descend through the upper edge of zero.

A rim 19 is provided at both front and rear edges and a lower edge of the trim main body 11, while one end of the reinforcement 30 in the longitudinal direction is applied to the rim 19 over its entire length in the longitudinal direction. A side wall 39 is provided.

The reinforcement 30 is bonded and fixed to the trim main body 11 with an olefin-based hot melt adhesive.
That is, the heated hot-melt type adhesive is applied to the front edge, the rear edge, and the lower edge of the back surface of the trim main body 11, or is applied to the back surface of the reinforcement 30 and then the side wall 39.
Is pressed against the inner surface of the rim 19 while the reinforcement 30
Is positioned at each edge of the trim body 11, and the hot melt adhesive is cooled and hardened.

In this manner, the three reinforcements 30
Are joined to the trim body 11 while positioning them, so that all the clip seats 31 to be arranged on the door trim 10 are attached. Therefore, it is not necessary to mount a large number of clip seats while positioning them one by one. Thus, the clip seat mounting operation can be greatly simplified.

In addition, as compared with the case where the clip seat is composed of a single body, the reinforcement 30 has a larger bonding area with the trim main body 11 and therefore has a larger bonding force. Further, since the side wall 39 and the rim 19 can be used as a reference for the arrangement position of the reinforcement 30, the reinforcement 30 can be easily positioned. Moreover, by bonding the side wall 39 and the rim 19 together, the bonding area is enlarged and the trim body 1
It is possible to further enhance the joining force between the reinforcement 1 and the reinforcement 30 and to enhance the rigidity of the rim 19 by reinforcing it.

Furthermore, the reinforcement 30 works together with the upper reinforcement 20 to reinforce the four ends of the trim main body 11, so that the trim main body 11 is warped or twisted. Such deformation can be prevented as much as possible.

When attaching the door trim 10 to the door frame, the clip 40 is engaged with the clip seat 31.
In mounting the clip 40, first, the head 40a of the clip 40 is inserted into the large hole 33a so that the neck 40b of the clip 40 is located exactly in the large hole 33a, and then the neck 40b is connected to the communication portion 33c.
Into the small hole portion 3 while pushing the communication portion 33c open.
Move to 3b. As a result, the clip 40 is engaged with the clip seat 31 so as not to fall off. And
By engaging the clip 40 with a clip engaging portion provided on the door frame, the door trim 10 is attached to the door frame.

In this embodiment, the door trim has been described. However, the present invention can be applied to various other vehicle trims such as a pillar trim and a quarter trim.

[0019]

As described above, according to the first aspect of the present invention, all the clip seats to be disposed on the trim are mounted by simply fixing the backing plate to the trim main body. Therefore, it is not necessary to mount the clip seats while positioning them one by one, and the mounting operation is greatly simplified.

According to the second aspect of the present invention, by reinforcing the edge of the trim main body of the door trim, it is possible to prevent the trim main body from being deformed such as warping or twisting.
