BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to interior parts, and more particularly to measures for preventing deformation of interior parts due to contraction of leather-made skin material.

[0002]

2. Description of the Related Art As for interior parts, for example, interior parts such as panels and lids for automobiles, as disclosed in Japanese Utility Model Publication No. 2-4840, a cushion material is integrally formed on the surface of the core material with the core material. There is a structure in which a skin material is formed, and the skin material covers the cushion material, wraps around the edge of the core material, and is adhered to the back surface of the edge.

In the above-mentioned interior product, an upright wall (see FIG. 3) having the same thickness as that of the other portion is protruded from the edge of the core material in order to maintain the shape of the edge of the upholstery, and the skin material is an upright wall And wound around the back surface of the edge of the core material and adhered to the back surface of the edge.

[0004]

By the way, in the above-mentioned interior goods, when leather is used as the skin material, the leather skin material shrinks when the temperature rises and returns to the original length when the temperature decreases. And a large shrinkage rate due to a temperature change.
For this reason, when the cabin temperature rises and the skin material shrinks,
A large force acts on the edge of the interior component from the skin material.

[0005] On the other hand, the interior product disclosed in the above publication has a structure in which all the force from the skin material acts on the edge of the core material, so that the core material is plastically deformed and warps. . For this reason, for example, in interior parts for automobiles,
There is a possibility that the in-vehicle component may be deformed due to a change in the vehicle interior temperature.

[0006] The present invention has been made in view of such a point, and prevents the core material from warping even when the skin material temporarily contracts, so that the interior product does not remain deformed. It is an object.

[0007]

Means for Solving the Problems In order to achieve the above object, a solution taken by the present invention is to provide a core material for retaining the shape of an interior product, a cushion material provided on the surface side of the core material, It is intended for an interior article having a leather skin material joined to the edge of the core material in a state in which the cushion material is covered and the edge is wound on the back side of the edge of the core material. The core material is provided so as to protrude from an edge of the core material along an edge of the skin material. When the skin material contracts, the core material is pulled by the skin material, and the end of the cushion material is pulled. A configuration is provided that includes a flexible protruding piece that bends to compress the edge.

[0008]

According to the present invention, the core material for retaining the shape of the interior product retains the edge shape of the interior product, while the leather skin material covers the cushioning material and the edge portion of the core material retains the interior material. Since it is joined to the edge of the core material while being wound on the back side of the edge, when the skin material shrinks, the force associated with the shrinkage acts on the edge of the interior article.

The core material is provided so as to protrude from the edge of the core material along the edge of the skin material, and is pulled by the skin material when the skin material contracts, so that the edge of the cushion material is provided. Is provided so as to compress the cushion material, and the protrusion is pushed into the cushion material to compress the cushion material. Therefore, the force acting on the edge of the interior product from the temporarily contracted skin material is absorbed by the cushion material via the protruding piece, and thus acts on the core material out of the force acting on the edge of the interior product. The force is reduced and no warping due to plastic deformation of the core material occurs.

The projecting piece 29A of this embodiment has a shape holding function of holding the outer peripheral edge shape by the shape holding portion 31 and the thin portion 33, and compresses the cushion material 25 by contraction of the skin material 27. It is configured to have a compression function.

Next, the operation of the lid portion 5 with respect to a temperature change in the vehicle interior will be described. As shown in FIG. 4, the shape holding portion 31 of the protruding piece 29A in the core material 23 holds the shape of the lower part of the outer peripheral edge portion 7a. Since the skin material 27 made of leather covers the cushion material 25 and is joined to the back surface of the core peripheral portion 23a in a state where the edge portion 27a is wrapped around the back surface side of the core peripheral portion 23a, the vehicle interior temperature increases. Then, when the skin material 27 contracts, a force accompanying the contraction acts on the outer peripheral edge portion 7a.

On the other hand, the core member 23 is provided so as to protrude from the core peripheral portion 23a along the edge portion 27a of the skin material 27, and when the skin material 27 contracts, the shape holding portion 31 is provided.

As shown in FIG. 3, when the temperature in the passenger compartment decreases and the skin material 27 returns to its original length, the force from the skin material 27 does not act on the projecting piece 29A, and the shape of the projecting piece 29A is reduced. The holding portion 31 is restored to the original shape by the cushion material 25. Therefore, the projecting piece 29 having a shape maintaining function
By A, when the skin material 27 is not contracted, the outer peripheral edge portion 7a can be restored to the original shape and the shape can be maintained.

FIGS. 5 and 6 show a second embodiment of the present invention. This embodiment is different from the first embodiment in that the protruding piece 29A has both the shape holding function and the compression function, but the protruding piece 29B having only the compression function is provided and the shape holding projection having the shape holding function is provided. The portion 35 is provided separately from the protruding piece 29B.

Specifically, the core material 23 includes the core peripheral portion 2.
The shape holding portion 35 is provided on the front surface side of 3a,
B are provided. The shape holding projection 35 is
A flat portion 37 extending laterally from the core peripheral portion 23a, and a hanging portion 39 hanging down from the tip of the flat portion 37 and contacting the skin material 27 so as to form an angular shape on the surface side of the core peripheral portion 23a.
It is composed of

The cushion member 25 is provided above the flat portion 37 of the shape holding projection 35 and is between the upper cushion portion 41 in contact with the flat portion 37 and the shape holding projection 35 and the projecting piece 29B. And an edge-side cushion portion 43 formed. On the other hand, the flat portion 37 is provided with a conduction hole 45 for forming the edge-side cushion portion 43 through which the resin for the cushion material can be conducted. The edge-side cushion portion 43 is configured such that, when an integrally molded product of the cushion material 25 and the core material 23 is manufactured, the resin for the cushion material is protruded from the upper cushion portion 41 forming space in the molding die and the shape holding projection 35. Are formed by flowing through a plurality of conduction holes 45 between the holes.

Then, the skin material 27 made of leather covers the upper cushion portion 41, comes into contact with the hanging portion 39 of the shape holding projection 35 and the edge side cushion portion 43, and projects from the back side of the projection piece 29B. It is adhered to the back surface of the protruding piece 29B and the back surface of the core material 23 while being wound on the back surface of the core material 23 above.

The projecting piece 29B is provided so as to be divided into a plurality of parts by notches (not shown) and project downward from the core peripheral part 23a along the edge part 27a of the skin material 27 and the first embodiment. As described above, since the thin portion 33 is not formed and the entire portion is formed to be thin, when the skin material 27 contracts, it is pulled by the skin material 27 and compresses the edge portion 25 a of the cushion material 25. Has the flexibility to bend.

Next, the operation of the lid portion 5 with respect to the temperature change in the vehicle interior will be described. As shown in FIG. 6, the shape holding portion 31 holds the shape of the surface of the outer peripheral portion 7 a without deforming even if the skin material 27 made of leather contracts due to a rise in the temperature in the vehicle interior.

On the other hand, the projecting piece 29B is provided with the contracted skin material 2
7 to compress the edge-side cushion portion 43. Therefore, the force acting on the outer peripheral edge portion 7a from the temporarily contracted skin material 27 is absorbed by the edge-side cushion portion 43 of the cushion material 25 via the protruding piece 29B, and thus the force acting on the outer peripheral edge portion 7a. Among them, the force acting on the core member 23 decreases, and the core member 23 does not warp due to plastic deformation.

When the temperature of the passenger compartment decreases and the skin material 27 returns to its original length and the force from the skin material 27 does not act on the protruding piece 29B, the protruding piece 29B is compressed by the edge-side cushion. The original shape is restored by the elastic force received from the part 43.

According to the present embodiment, it is possible to prevent the core member 23 from warping due to plastic deformation and to prevent the outer peripheral edge shape from remaining deformed.

Further, even when the skin material 27 contracts, the shape of the surface of the outer peripheral portion 7a seen from the passenger compartment when the lid 5 is closed can be held by the shape holding portion 31 without being deformed. Since the portion deformed by the protruding piece 29B is on the back surface side of the outer peripheral edge portion 7a, the deformed portion can be hidden from the vehicle compartment side, and the appearance of the lid portion 5 when the lid is closed can be improved.

The interior parts of the present invention may be, for example, panels for automobiles other than the lid part 5 of the console box 1 for automobiles described above, and may be used for applications other than automobiles. .

[0037]

As described above, according to the present invention, the core material is provided so as to protrude from the edge of the core material along the edge of the skin material. Since it has the flexibility of being pulled by the skin material and flexing so as to compress the edge of the cushion material, the force acting on the edge of the interior component from the temporarily contracted skin material causes the protruding piece to move. The force acting on the core material is reduced because it is absorbed by the cushion material via the cushion material. Therefore, even if the skin material is made of leather having a large shrinkage, warpage due to plastic deformation of the core material can be prevented, and it is possible to prevent the interior product from remaining deformed.
