Description

The present invention relates to an interior material for a vehicle having a skin.

Conventionally, an interior material for a vehicle may be composed of a base material and a skin, or a combination of a base material, a cushioning material and a skin material, and as the skin, for example, a skin having a grain similar to genuine leather is used. In many cases. Then, by preparing a plurality of such skins, connecting them by sewing and arranging them on the front side of the vehicle interior material, the texture of the design surface is improved.

In Patent Document 1, the end edges of two skin materials are sewn together with a thread in a state of being overlapped with each other, one of the skins is folded back from the sewn portion as a starting point, and the portion where the skins overlap is sewn with a thread, so-called. A method called single stitch is disclosed. On the epidermis sewn with a single stitch, an institch appears at the seam of the two epidermis, and an outstitch appears in parallel with this institch.

If the skin is actually sewn using a thread as in Patent Document 1, it takes time and effort to sew and the cost increases. Therefore, as disclosed in Patent Document 2, for example, the design is made of a resin material. A pseudo stitch pattern is formed on the surface. In Patent Document 2, a first member formed by arranging a large number of thread portions to be pseudo stitches side by side on the front side and a second member formed so as to cover the front side of the first member with only the thread portions exposed are combined. This allows the stitch pattern to be formed without the use of threads. The first member and the second member are molded in two colors.

By the way, in Patent Document 2, a large number of thread portions are formed so as to be lined up on the first member, and in general, the spacing between adjacent thread portions needs to be set narrowly so as to correspond to an actual stitch, and the thread threads are set to be narrow. Since the portion itself has a thin shape, it is difficult to accurately mold such a thread portion at the time of two-color molding, and it is considered that a beautiful stitch pattern cannot be formed.

Further, in the case of Patent Document 2, since the epidermis itself is composed of the second member, it only looks like two epidermises are connected to each other, and it actually becomes one monochromatic epidermis. It ends up. Therefore, it is not possible to realize a design in which different colored skins are joined together, and in order to realize this, a method of joining two different colored skins using a thread as in Patent Document 1 is used. I had to use it.

The present invention has been made in view of this point, and an object of the present invention is to make it possible to realize a design in which epidermises of different colors are joined together without using a thread.

It has a second skin component made of wood, and the first skin component and the second skin component are joined in a groove formed on the surface of the skin, and two pieces are formed in the groove. A pseudo-institch pattern resembling an institch formed when the cloth is sewn on the ground and folded back in a direction away from each other is formed, and the end portion of the first skin component portion is bent toward the back side of the skin. A plurality of protrusions formed so as to extend along the back surface of the end portion of the second skin constituent portion, and projecting toward the front side to form the pseudo-institch pattern at the end portion of the first skin constituent portion. Is provided at a distance from each other in the longitudinal direction of the groove portion .

According to this configuration, the first skin component and the second skin component made of resin materials of different colors are joined to each other, so that the design is as if the skins of different colors are joined together. Since the first epidermis constituent part and the second epidermis constituent portion are joined in the groove portion on the surface of the epidermis, the joint portion becomes inconspicuous, and the groove portion has a pseudo-institch pattern which is a pattern like an institch. Is formed, so that a texture as if two skins are sewn together can be obtained.

Further, since the pseudo-institch pattern is formed by the plurality of protrusions provided on the first skin constituent portion, the pseudo-institch pattern can be easily formed.

The second invention is characterized in that the end portion of the first epidermis constituent portion is arranged and joined so as to overlap the back surface of the end portion of the second epidermis constituent portion.

According to this configuration, a wide joint area between the first skin component and the second skin component is secured .

A third aspect of the invention is characterized in that the end portion of the second epidermis component is abutted against the first epidermis component at the bottom of the groove.

According to this configuration, the joint portion between the first epidermis constituent portion and the second epidermis constituent portion becomes more inconspicuous.

According to a fourth aspect of the present invention, the vehicle interior material is an armrest provided by a door trim attached to the vehicle interior side of a vehicle door, the first skin component is provided on the upper side of the armrest, and the lower side of the armrest. The second skin component is provided in the above.

According to this configuration, the color of the armrest changes between the upper side and the lower side, and a pseudo-institch pattern is formed between them, so that a texture as if the armrest is covered with a plurality of skins can be obtained, and a good design can be obtained.

In the fifth aspect of the invention, a concave portion extending in parallel with the groove portion is formed in a portion of the first epidermis constituent portion separated from the groove portion in the width direction, and an outstitch pattern is formed on the concave portion by a thread. It is characterized by being formed.

According to this configuration, an outstitch pattern extending in parallel with the pseudo institch pattern is formed in the first skin constituent portion, so that the texture as if the skins are sewn together is further enhanced.

According to the first invention, a first skin component made of a resin material and a second skin component made of a resin material having a color different from that of the first skin component are joined in a groove portion, and the groove portion is simulated. Since the institch pattern is formed, it is possible to realize a design in which different colored epidermises are joined together without using threads.

Further, the end portion of the first epidermis constituent portion is bent so as to extend along the back surface of the end portion of the second epidermis constituent portion, and a pseudo-institch pattern is formed on the end portion of the first epidermis constituent portion. Since a plurality of protrusions are provided for the purpose, a pseudo-institch pattern can be easily formed.

According to the second invention, since the end portion of the first epidermis constituent portion is arranged and joined so as to overlap the back surface of the end portion of the second epidermis constituent portion, the first epidermis constituent portion and the second epidermis configuration portion are joined. Sufficient joint strength with the part can be secured .

As shown in FIG. 4, the groove portion 30a of the epidermis 30 is formed at the boundary portion between the upper epidermis constituent portion 31 and the lower epidermis constituent portion 32, and has a cross-sectional shape such that the width becomes narrower as it approaches the bottom portion. It has, and its cross-sectional shape becomes sharp toward the bottom side. The groove portion 30a can also be referred to as a ground stitch groove portion. At the bottom of the groove 30a, a protrusion 31b having a pseudo-institch pattern is formed. The institch is a stitch (stitch) that can be made when two pieces of cloth (skin) are sewn together (when the ground stitch is sewn). In the present embodiment, since the feeling that the two skins are sewn together is obtained without using the two skins, there is actually no institch. By forming a plurality of protruding portions 31b having a stitch pattern similar to this institch at predetermined intervals in the longitudinal direction of the groove portions 30a, the groove portions 30a are folded back in a direction away from each other after the two skins are sewn together. It looks like a groove with an institch made of.

As shown in FIG. 5, the protruding portion 31b protrudes toward the front side from the stepped portion 31a of the upper skin constituent portion 31 and has a plate shape extending in a direction intersecting the longitudinal direction of the groove portion 30a. The spacing between the protrusions 31b can be set arbitrarily, but it is preferable to set the spacing so that a general institch can be reproduced. The protruding height of the protruding portion 31b is set so that only the tip portion of the protruding portion 31b in the protruding direction protrudes to the front side from the joint portion between the upper end portion of the lower skin constituent portion 32 and the upper skin constituent portion 31. .. The tip of the protruding portion 31b in the protruding direction slightly protrudes from the joint portion between the upper end portion of the lower skin constituent portion 32 and the upper skin constituent portion 31, so that it looks as if an institch is present.

As shown in FIG. 4, an upper concave portion (stitch groove portion) 31c extending in parallel with the groove portion 30a is formed in a portion of the upper skin constituent portion 31 separated from the groove portion 30a upward (in the width direction of the groove portion 30a). Has been done. An outstitch pattern is formed on the upper concave portion 31c by the thread 31d. The thread 31d is a member forming a stitch along the upper concave portion 31c, and an outstitch pattern is obtained by sewing the upper skin constituent portion 31.

A lower concave portion (stitch groove portion) 32c extending in parallel with the groove portion 30a is formed at a portion of the lower skin constituent portion 32 that is separated from the groove portion 30a downward (in the width direction of the groove portion 30a). An outstitch pattern is formed on the lower concave portion 32c by the thread 32d. The thread 32d is a member forming a stitch along the lower concave portion 32c, and an outstitch pattern is obtained by sewing the lower skin constituent portion 32. The outstitch pattern of the upper skin constituent portion 31 and the lower skin constituent portion 32 may be provided as needed, may be omitted, or may be a double outstitch pattern. Further, it may be a stitch pattern having a different color.

For example, as in the modification 1 of the embodiment shown in FIGS. 6 and 7, the anchor portion 32e may be provided on the lower skin constituent portion 32. The anchor portion 32e protrudes from the back surface of the upper end portion of the lower skin constituent portion 32, penetrates the lower end portion of the upper skin constituent portion 31 to the back surface, and is integrated with the upper skin constituent portion 31. As a result, the upper end portion of the lower skin constituent portion 32 is less likely to be rolled up from the upper skin constituent portion 31.

(Production method)
Next, a method of manufacturing the armrest 1 configured as described above will be described. The base material 10 and the cushion material 20 are preliminarily molded by a molding device (not shown). Further, the manufacturing method may be, for example, a method in which a single skin 30 is molded by a skin molding mold, an outstitch is sewn on the skin 30, and then the cushion material 20 and the base material 10 are coated with the skin 30. In this method, the cushion material 20 and the base material 10 are molded by a molding die different from the skin molding die.

For example, the molding apparatus A as shown in FIG. 8 is prepared. The molding apparatus A is a drive device for driving the first molding die 200, the second molding die 210 and the third molding die 202, and the first molding die 200 and the third molding die 202 for molding the upper skin constituent portion 31. (Not shown) and. The first molding die 200 has a molding surface 200a for molding the upper skin constituent portion 31.

As shown in FIG. 8, the first molding die 200 and the third molding die 202 are driven by a driving device in a direction approaching the first molding die 200 to close the mold, and the cavity C1 is formed inside. The cavity C1 is for molding the upper skin constituent portion 31. The cavity C1 is filled with a molten resin material, which is a material for the upper skin constituent portion 31, by being supplied from an injection machine (not shown). When this resin material is solidified, the upper skin constituent portion 31 is obtained as shown in FIG.

(Action and effect of the embodiment)
As described above, according to this embodiment, the upper skin constituent portion 31 and the lower skin constituent portion 32 made of resin materials of different colors are joined and integrated, so that the skins of different colors are connected. It will be a combined design. Since the upper skin constituent portion 31 and the lower skin constituent portion 32 are joined in the groove portion 30a on the surface of the skin 30, the joint portion becomes inconspicuous, and the groove portion 30a has a pattern like an institch. Since the pseudo-institch pattern is formed by the protruding portion 31b, it is possible to obtain a texture as if two skins are sewn together without using a thread.

The above embodiments are merely exemplary in all respects and should not be construed in a limited way. Further, all modifications and modifications belonging to the equivalent scope of the claims are within the scope of the present invention.

Further, in the above embodiment, the case where the present invention is applied to the armrest 1 has been described, but the present invention is not limited to this, and the present invention may be applied to the skin of the main body of the door trim 100, the skin of the instrument panel, and the skin of various lids. can.
