Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to automobile interior parts such as automobile door trims.

[0002]

[Prior art]

 For example, as shown in FIGS. 4 and 5, an automobile door trim 1 has a core material 2 formed into a required shape, and a surface material 3 having cushioning and decorative properties is integrally attached to the surface side by vacuum forming or the like. In many cases, the door trim 1 can be attached to the vehicle body panel 4 by attaching a bulging embossed portion to the back surface of the core material 2 at a predetermined position as shown in FIG. The door trim 1 is configured as the clip mounting seat 5, the clip 6 is mounted in the mounting hole 5a of the clip mounting seat 5, and the clip 6 is press-fitted into the mounting hole 4a of the vehicle body panel 4, thereby the door trim 1 is mounted on the vehicle body panel. I am trying to attach to 4.

Further, the clip mounting seat 5 formed on the core material 2 has a shape embossed on the back surface side, and becomes a concave portion on the product surface when the skin material 3 is vacuum-bonded to the core material 2. Since it appears, a blind lid 7 made of an iron plate or the like is usually installed so as to close the embossed space of the clip mounting seat 5.

[0004]

[Problems to be solved by the device]

 As described above, in the door trim 1 having the structure in which the clip mounting seat 5 is integrally formed with the core material 2 to which the skin material 3 is attached by vacuum forming, the depth of the clip mounting seat 5 (shown by a in FIG. 5) Is about 10 mm, and in order to set the clip mounting seat 5 to a deeper dimension, the area of the clip mounting seat 5 must be set large due to the formability of the core material 2. In such a case, the skin material At the time of vacuum bonding of No. 3, the blind lid 7 cannot withstand the vacuum pressure, the blind lid 7 is curved, and a dent is formed on the product surface.

Therefore, when the clip mounting seat 5 is provided integrally with the core member 2, the depth of the clip mounting seat 5 is restricted, and therefore the clear clearance between the door trim 1 and the vehicle body panel 4 is also restricted. However, there was a problem that the degree of freedom in shaping the product was greatly restricted.

Further, in order to increase the molding freedom regardless of the clearance between the door trim 1 and the vehicle body panel 4, it is necessary to set a separate clip mounting seat, which increases the number of parts and the number of mounting steps. As a result, there was a problem that the cost was significantly increased.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide an automobile interior part having a structure in which a surface material is covered and adhered to the surface of a core material by vacuum forming. In order to provide interior parts for automobiles, the size of the embossed part of the clip mounting seat formed on the core material can be set arbitrarily, and the degree of freedom in molding can be dramatically improved with a simple and inexpensive structure. is there.

[0008]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention comprises a core material formed into a required shape, a skin material being crimped by vacuum forming, and a back surface on which a clip is mounted at a predetermined position of the core material. In an automobile interior part in which an embossed clip mounting seat that bulges to the side is molded, a blind lid is housed inside the clip mounting seat, and this blind lid is installed inside the clip mounting seat. It is composed of a synthetic resin injection molded body that integrally forms a base that closes the embossed space, a bottom that extends downward from the back of this base, and the tip contacts the inner surface of the clip mounting seat to prevent deformation of the base. It is characterized by being

[0009] In addition, a contact rib for pressing the head flange portion of the clip is integrally formed on the back surface of the base of the blind lid.

[0010]

[Operation] As is clear from the above configuration, when the blind lid is installed in the clip mounting seat, the base of the blind lid closes the embossed space, and the deformation prevention protrusions provided on the back surface of the base are attached to the inner surface of the embossed portion. Since they abut, when the vacuum-bonding the skin material to the core material, even if a vacuum pressure is applied to the base, the deformation preventing projections function as stoppers, so the base does not deform.

Further, by setting a contact rib for pressing the head flange portion of the clip on the back surface of the base plate, when the interior parts are mounted on the vehicle body panel, the pressing force applied to the surface of the interior parts can be directly transmitted to the clip. The parts can be mounted efficiently.

[0012]

【Example】

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

1 to 3 show an embodiment in which the present invention is applied to an automobile door trim. FIG. 1 is a front view of the automobile door trim, and FIG. 2 is a state in which the automobile door trim is attached to a vehicle body panel. FIG. 3 is an explanatory view showing the shape of the clip mounting seat.

In FIGS. 1 and 2, a vehicle door trim 10 is configured by covering a surface of a core member 20 formed into a required shape with a skin material 30 by vacuum forming.

More specifically, as the core material 20, a fiber mat impregnated with a thermosetting resin is molded into a desired curved surface shape by hot press molding. It has mounting rigidity.

On the other hand, the skin material 30 has cushioning properties and decorative properties, and uses a composite sheet in which a foam layer such as polyethylene foam is lined on the back surface of the PVC sheet. Since it is worn, it must be non-breathable.

To attach the vehicle door trim 10 to the vehicle body panel 40, as shown in FIG. 2, an embossed clip attachment seat 21 facing the vehicle body panel 40 side is formed at a predetermined position of the core member 20. The door trim 10 is mounted on the vehicle body panel 40 by press-fitting the clip 60, which is previously mounted in the mounting hole 23 provided in the clip seat portion 22 of the clip mounting seat 21, into the mounting hole 41 of the vehicle body panel 40. I am trying to attach it to.

By the way, the feature of the present embodiment resides in the configuration of the blind lid 50 installed in the embossed clip mounting seat 21.

That is, the blind lid 50 is made of a synthetic resin injection-molded body, and has a base 51 that closes the embossed space of the clip mounting seat 21 and a clip of the clip mounting seat 21 that extends downward from the back surface of the base 51. It is composed of a deformation preventing projection 52 that comes into contact with the inner surface of the seating portion 22, and a contact rib 53 that projects from the back surface of the base 51 in the approximate center and abuts against the head flange 51 of the clip 50.

A sealing paper tape 54 is adhered to the surface of the base 51 of the blind lid 50 to prevent the skin material 30 from floating and prevent air leakage from the periphery of the base 51.

As described above, according to this embodiment, the blind lid 50 having the deformation preventing projection 52 and the contact rib 53 formed on the back surface of the base 51 is installed in the clip mounting seat 21. When vacuum-adhering the skin material 30 to the surface of the material 20, if the vacuum molding is performed with the blind lid 50 housed in the clip mounting seat 21, the tip of the deformation preventing projection 52 is the clip of the clip mounting seat 21. Since it is in contact with the inner surface of the seating portion 22, the deformation preventing projection 52 functions as a stopper, and does not deform even when a suitable vacuum pressure is applied to the base 51, so that the desired shape can always be maintained and the door trim. 10 It does not appear as a dent on the surface.

Therefore, conventionally, the embossing depth of the clip mounting seat 21 is limited to within 10 mm, but according to the present embodiment, even if the embossing depth of the clip mounting seat 21 is arbitrarily set, Due to the deformation prevention function of the blind lid 50, when the skin material 30 is vacuum-bonded, no recess appears on the product surface, so the freedom of molding of the door trim 10 is increased without being restricted by the clearance between the door trim 10 and the vehicle body panel 40. Can be improved.

Further, since the contact ribs 53 projectingly formed on the back surface of the base 51 are in contact with the head flange portion 61 of the clip 50, for example, when the door trim 10 is attached to the vehicle body panel 40, the surface of the door trim 10 should be pressed. For example, since the pressing force is transmitted to the direct clip 50 via the contact rib 53, the door trim 10 can be efficiently attached to the vehicle body panel 40.

FIG. 3 shows the appearance of the blind lid 50 used in this embodiment. In this embodiment, the deformation preventing projection 52 is formed by a plate-shaped rib, but an annular rib or a circular boss may be used. The shape is not particularly limited as long as it has a stopper function.

The contact rib 53 may be omitted if desired, and the contact rib 53 is not an essential component.

Further, although the base 51 has a flat shape in the drawing, if the product surface corresponding to the clip mounting seat 70 is set to have a curved shape, it is curved so as to match the curved shape. It can be set in a shape.

Although the embodiment in which the present invention is applied to the automobile door trim 10 has been described above, the present invention can be applied to general interior parts such as a rear corner trim.

[0028]

[Effect of device]

 As described above, the present invention has the special operational effects described below.

(1) According to the present invention, since the deformation preventing protrusion is formed on the base of the blind lid, even if the embossing depth of the embossed portion formed on the core is set deep, the product surface is not exposed. It has the effect that the appearance design of interior parts can be improved without the appearance of recesses.

(2) According to the present invention, by providing the deformation preventing protrusion on the back surface of the base of the blind lid, the embossing depth of the embossing portion formed on the core material can be arbitrarily set, so that the interior component This has the effect of dramatically improving the molding flexibility of the product without being restricted by the clearance between the vehicle body panel and.

(3) According to the present invention, by setting the contact rib on the back surface of the base of the blind lid so as to abut the head flange portion of the clip, when the interior parts are mounted on the vehicle body panel, the pressing force of the interior parts is reduced. Since it can be directly transmitted to the clip via the contact ribs, the interior parts can be efficiently attached.
