Description

  TECHNICAL FIELD The present invention relates to an interior part for an automobile in which a surface material is covered on a surface of a core material.

  Interior parts such as a cover of an automobile console box have a structure in which a surface material is covered on a surface of a core material. The core material is made of resin, and has an outer wall extending around the back surface of the core material around the top plate. The skin material generally has a urethane foam layer on the back surface of the skin. The skin material is sewn in a bag shape and covered from the top plate side of the skin material, and the periphery of the skin material is folded back on the back surface of the outer wall of the core material and fixed.

  As shown in Patent Document 1, a metal tucker is often used as a means for fixing the peripheral portion of the skin material to the outer wall of the core material. However, skill is required to use a tucker to uniformly fix the skin material at the corners of the core material without wrinkling. In addition, since the tucker is driven from the inside to the outside of the outer wall of the core material, if it is broken, the tip of the tucker may protrude toward the skin material side.

  In addition, adhesives are used to fix the periphery of the skin material to the outer wall of the core material.However, it takes time for the adhesive to dry, and when the inside of the car becomes hot, Could loosen, and there were concerns about durability.

  Therefore, the present inventors sewed a resin band having a fixed width around the periphery of the skin material, and elastically folded the resin band inside the outer wall of the core material, so that the skin was not used with a tucker or an adhesive. A technique for fixing a material has been developed and has been proposed as Patent Document 2. However, this technique has no problem when the height of the outer wall of the core material is constant, but has a problem that it cannot be applied to a portion where the height of the outer wall of the core material changes. The reason for this is that, at a portion where the height of the outer wall of the core material changes, the shape of the peripheral portion of the skin material is not straight, so that a resin band having a constant width cannot be sewn.

  Accordingly, an object of the present invention is to solve the above-mentioned conventional problems and to provide an interior component in which a skin material is fixed without using a tucker or an adhesive regardless of the shape of an outer wall of a core material.

  The interior component of the present invention made in order to solve the above problems, a concave core material having an outer wall around the periphery, a skin material covering the surface of the core material, and an inner lid fixed to the back surface of the core material A resin core material in which a wavy piece is integrally formed on one side of a shaft core portion is sewn to a peripheral portion of a skin material, and the peripheral portion of the skin material is cored together with the core material. The material is folded on the back side of the outer wall of the material, and the shaft core of the core material is restrained at the end of the inner lid.

  In a preferred embodiment, a plurality of retaining ribs are formed inside the outer wall of the core material. Further, the end of the inner lid has a folded portion for restraining the shaft core of the core material.

  The interior part of the present invention has a structure in which the periphery of the skin material is folded together with the core material on the back surface side of the outer wall of the core material, and the shaft core of the core material is restrained at the end of the inner lid. The skin material can be fixed to the core material without using any. The core material used for the interior part of the present invention is a resin product in which a wavy piece is integrally formed on one side of a shaft core, and unlike a resin band having a constant width shown in Patent Document 2, an arbitrary direction is used. Can be bent. For this reason, it is possible to sew while freely bending even a portion where the shape of the peripheral portion of the skin material is not linear, and the skin material can be fixed regardless of the shape of the outer wall of the core material. Further, in the interior component of the present invention, the end of the inner lid restrains the shaft core of the core material, so that the end of the skin material is firmly fixed to the core material, and is superior to the interior component of Patent Document 2. It has the advantage of having high pull-out strength.

It is an appearance perspective view showing an interior part of an embodiment. It is the perspective view which looked at the core material from the bottom side. It is a perspective view showing the state where the core material was sewn on the peripheral part of the skin material. It is sectional drawing of a principal part. It is a perspective view of a core material.

Hereinafter, preferred embodiments of the present invention will be described.
FIG. 1 is an external perspective view showing the interior component of the embodiment, and FIG. 2 is a bottom perspective view showing the core material. Although the interior component of the embodiment is a console lid of an automobile, the present invention is not limited to this. This interior part is obtained by covering a surface of a core material 10 shown in FIG. 2 with a skin material 11 as shown in FIG. In this embodiment, the skin material 11 is a skin material with a cushion layer.

  The core material 10 is a concave body made of hard resin, and has an outer wall 13 extending toward the back side around the top plate 12 as shown in FIG. In this embodiment, the outer wall 13 can be used for an object having a constant height, but a portion near the right corner in FIG. 2 includes a portion where the height of the outer wall 13 is continuously changed. The invention can also be used for parts where the height of the outer wall 13 is not constant. A plurality of retaining ribs 14 are formed inside the outer wall 13. The retaining rib 14 is provided with a projection 15 which is several mm away from the outer wall 13 as shown in FIGS. The position and the number of the retaining ribs 14 can be appropriately set according to the size and shape of the core material 10, but in this embodiment, the retaining ribs 14 are arranged at intervals of 30 to 50 mm.

  Reference numerals 16 and 17 shown in FIG. 2 denote projections for attaching the inner lid 20 to the back surface of the core material 10, and the projections 17 are formed with pilot holes 18 for screwing tapping screws. On the back surface of the core material 10, a fitting clip 33 for fitting by a fitting structure is formed. Note that 19 shown in FIG. 2 is a pad layer made of urethane foam formed on the upper surface (the lower surface in FIG. 2) of the top plate 12 of the core material 10, but 19 is not necessarily required.

  The skin material 11 is sewn in a bag shape in the same manner as in the related art so as to cover the core material 10. As shown in FIG. 3, in the present invention, a core material 30 is sewn to the periphery of the skin material 11. As shown in FIG. 5, the core material 30 is made of a resin in which a corrugated piece 32 is integrally formed on one side of a shaft core portion 31. In the present embodiment, the shaft core portion 31 is hollow, and has a structure in which a wave-shaped wavy piece 32 is formed from the center thereof. The shaft core 31 is not hollow and may be solid.

  The core material 30 is sewn to the periphery of the skin material 11 so that the shaft core portion 31 is located at the periphery of the skin material 11. The shape of the wavy piece 32 is not limited to a curved shape as in the illustrated embodiment. The shape may be a linear waveform.

  The shape of the peripheral portion of the skin material 11 changes according to the height of the outer wall 13 of the core material 10, and in the portion where the height of the outer wall 13 is not constant, the peripheral portion of the skin material 11 has a bent portion or a curved portion. Parts may occur. The resin band having a constant width shown in Patent Document 2 cannot correspond to such a portion, but the core material 30 having the wavy pieces 32 used in the present invention can be bent in an arbitrary direction. Therefore, even if there is a bent portion or a curved portion on the periphery of the skin material 11, the sewing can be performed without any trouble.

  After covering the outer surface of the core material 10 with the skin material 11 having the core material 30 sewn on the peripheral edge in this way, the peripheral edge of the skin material 11 together with the core material 30 is formed as shown in FIG. Fold it on the back side of the outer wall 13. As a result, in the portion where the retaining rib 14 is present, the peripheral edge of the skin material 11 enters between the projection 15 of the retaining rib 14 and the outer wall 13 of the core material 10. Further, in the portion between the retaining ribs 1214, the peripheral edge of the skin material 11 is held on the back surface side of the outer wall 13 by the rigidity of the core material 30.

  However, if the peripheral edge of the skin material 11 is simply inserted between the protrusion 15 of the retaining rib 14 and the outer wall 13 of the core member 10 when the peripheral edge of the skin material 11 is strongly pulled, the peripheral material may fall off. Therefore, in the present invention, as shown in FIG. 4, a folded portion 21 is formed at the end of the inner lid 20 that covers the back surface of the core material 10, and the folded portion 21 is formed between the protrusion 15 of the rib 14 and the core material 10. It was inserted between the outer wall 13 and the shaft core 31 of the core 30 was constrained by the tip 22 of the folded portion 21. Since the shaft core portion 31 is larger in diameter than other portions of the core member 30, the shaft core portion 31 does not fall off when pressed by the tip end 22 of the folded portion 21. The inner lid 20 is firmly fixed to the back surface of the core material 10 by a tapping screw or a clip fitting structure.

  The interior member of the present invention thus configured can securely fix the peripheral portion of the skin material 11 without using a tucker or an adhesive, regardless of the shape of the outer wall 13 of the core material 10. The console lid is subjected to a pull-out strength test of the peripheral portion of the skin material 11, but the interior member of the present invention does not use a tacker or an adhesive, and the peripheral portion of the skin material 11 is not subjected to a predetermined pulling load. The part does not fall off the outer wall 13 of the core material 10.

  In addition, the interior member of the present invention can be simply inserted by inserting the peripheral edge of the skin material 11 between the protrusion 15 of the retaining rib 14 and the outer wall 13 of the core material 10 and attaching the inner lid 20. It is possible to manufacture even if it is not, and it is excellent in aesthetic appearance without wrinkles and slacks even in corner portions.

  In the above-described embodiment, there was a portion where the height of the outer wall 13 of the core material 10 was continuously changed. However, the outer wall 13 may have a uniform height over the entire circumference of the core material 10 as a matter of course.

  Further, in the present embodiment, of the outer wall 13 of the core material 10, the outer wall 13 is too low on the lower left side of FIG. It is fixed to. Thus, it is not always necessary to apply the fixing structure of the present invention over the entire circumference of the outer wall 13 of the core material 10.
