Description

[Detailed Description of the Invention] << Industrial Application Field >> This invention is an automobile interior part in which a block-shaped cushioning material having a spacer function and a low-grade sound prevention function is installed on the back side of an interior panel made of a resin molding. Regarding

<< Prior Art >> As is well known, various interior parts such as an automobile door trim are mounted on the inner surface side of an automobile body panel.

FIG. 5 shows an automobile door trim 1 as a typical interior part. The automobile door trim 1 is formed into a required shape by injection molding a synthetic resin. When an external force is applied from the inside to the inner panel side, a cushioning material 2 such as chip urethane is adhesively fixed as shown in FIG. 6 so as not to be easily bent by the elasticity of the resin and to prevent a so-called sticky feeling. In addition, as shown in FIG. 7, in order to prevent generation of chattering noise, rattling noise, and other low-quality sounds between the door trim 1 and the vehicle body panel 3 due to vibrations during traveling, the terminal portion of the door trim 1 is prevented. A cushioning material 4 such as urethane is bonded and fixed to the back surface side of the.

Further, as a countermeasure against this low-grade sound, a tape-shaped cushioning material such as a non-woven tape or urethane tape having appropriate elasticity may be used in place of the cushioning material such as urethane.

<Problems to be solved by the invention> However, in the door trim 1 having the above-described conventional structure, when the cushioning materials 2 and 4 having the spacer function and the low-grade noise prevention function are bonded and fixed, for example, the cushioning material serves as a spacer. In order to fix 2, the cushion material tends to be peeled off by an external force because the gap between the door trim 1 and the vehicle body panel 3 is large, so that not only does it not satisfy the sufficient spacer function but also the strength is maintained. In order to do so, the size of the cushioning material 2 must be set large, and it has been pointed out that there is a problem that the cost rises due to the high material cost.

In addition, in the cushioning material 4 as a measure for low-grade sound, since the sticking position is unclear, it is pointed out that the sticking work is troublesome and the workability is deteriorated, and the cushioning material 4 protrudes from the product terminal. In such a case, careful attachment work is required because the appearance is remarkably impaired, and this is also one of the factors leading to a decrease in workability.

The present invention has been made in view of such circumstances, and an object of the present invention is to provide a block-shaped cushioning material having a spacer function and a low-level sound prevention function on the back side of an interior panel made of a resin molded body. For interior parts of the type to be set, the cushioning material can be installed easily and quickly, the mounting strength can be sufficiently guaranteed, and the function is satisfied even with a downsized cushioning material. Is to provide interior parts for automobiles.

<Means for Solving the Problems> In order to achieve the above object, the present invention provides an interior panel made of a resin molded body that is molded into a required shape and is installed inside the vehicle body panel with a predetermined clearance. In an automobile interior part composed of a block-shaped cushioning material attached to a predetermined position on the back surface of the interior panel in order to absorb a pressing load applied to the front side of the interior panel and reduce a frictional noise between the interior panel and the vehicle body panel. A cushioning material holding rib for holding the side surface of the cushioning material by sandwiching is provided at a predetermined location on the back surface side of the interior panel at the cushioning material installation location on the back surface side of the interior panel.

<Operation> As is apparent from the above configuration, according to the present invention, since the cushioning material holding rib for holding the side surface of the block-shaped cushioning material is set on the back side of the interior panel, the cushioning material installation location is set. Since it is clear and a simple operation of fitting the cushioning material into this rib is sufficient, the work of attaching the cushioning material can be performed easily and quickly.

Further, since the mounting strength of the cushioning material is ensured by the cushioning material holding rib, a firm mounting strength can be expected without setting a large size of the cushioning material.

<Example> Hereinafter, an example of an automobile interior part according to the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a partially cutaway perspective view of a vehicle door trim to which the present invention is applied, FIGS. 2 and 3 are cross-sectional views of a main part of the vehicle door trim, and FIG. 4 is a diagram showing another embodiment of the present invention. FIG.

1, an automobile door trim 10 according to the present invention is shown.
Is an interior panel 20 made of an injection-molded body of synthetic resin and having a required curved surface shape, a cushioning material 30 having a spacer function installed on the back side of the interior panel 20, and a cushioning material having a low-grade sound prevention function. It consists of 31 and.

In the present example, chip urethane is used as the cushioning materials 30 and 31, but felt or the like may be applied, and the material thereof is not particularly specified.

Further, the present invention is characterized by the mounting structure of the cushioning members 30 and 31. That is, the cushioning material holding ribs 21 and 22 for holding the cushioning materials 30 and 31 are formed so as to project from the back surface side of the interior panel 20.

Therefore, as shown in an enlarged manner in FIG. 1, the cushioning material 30 having a spacer function with the vehicle body panel 40 is structured such that the cushioning material 30 is held by the pair of plate-shaped ribs 21 having a predetermined interval. (See FIG. 2) The cushioning material 30 slightly protrudes from the tip of the rib 21, and when the body panel 40 and the tip of this cushioning material 30 come into contact with each other, the sticky feeling of the door trim 10 is eliminated and an effective spacer is provided. It is configured to have a function.

In addition, as a countermeasure against low-grade noise such as chattering noise and rattling noise while traveling, as for the cushioning material 31, as shown in FIG. The cushioning material 31 is attached by the ribs 22, and the body panel 40
By making contact with the cushioning material 31, the generation of the low-grade sound described above is prevented in advance.

Since the present invention is configured as described above, the ribs 21 and 22 are
In addition, since the cushioning material 30, 31 may be fitted and fixed by adhesion, the pasting position of the cushioning material is unclear as in the conventional case, so that it is possible to effectively solve the conventional trouble such as troublesome work. .

Further, in the cushioning material 30 having the spacer function, since the strength is guaranteed by the ribs 21, the cushioning material 30 held by the ribs 21 even if its size is set small.
Has sufficient strength without wobbling.

Further, as shown in FIG. 4, an intermediate wall 23 is provided at an intermediate position of the rib 21.
