Description

The present invention relates to a skin member used to cover a base member, and an interior member whose base member is covered with the skin member.

JP 2019-89536A (Patent Document 1) describes a skin member that covers a base material portion. The skin member described in Patent Document 1 is made by bending the side edges (skin side edges) of two skin pieces into a U-shape, and then connecting the bent portions of the side edges to each other. They are formed by butting each other and sewing them together.

Conventionally, when a skin member is placed on a base material part, an adhesive is applied to the surface of the base material part to form an adhesive layer, and at the same time, as shown in FIG. The adhesive layer 95 may also be formed by applying an adhesive. Thereby, the base material part and the skin member 90 can be bonded together via the adhesive layer of the base material part and the adhesive layer 95 of the skin member 90. Further, in this case, for the left and right skin pieces 91 of the skin member 90, an adhesive is applied to the entire inner circumferential surface of the skin side edge 92 of each skin piece 91 to form an adhesive layer 95. The U-shaped bent shape of the edge 92 may be fixed.

JP2019-89536A

As shown in FIG. 7, the skin member 90 is attached (fixed) by being placed over the base material portion with the skin side edges 92 of the left and right skin pieces 91 being respectively bent into a U-shape. . In such a conventional skin member 90, for example, when the skin member 90 is formed in a curved shape so that the portion where the left and right skin pieces 91 abut are curved left and right, the skin member 90 is bent into a U-shape. The back side (the so-called seam allowance part) of the outer skin side edge 92 tends to become twisted, and wrinkles may occur partially on the back side.

However, in this skin member 90, the U-shaped bent shape of the skin side edge 92 is fixed by the adhesive layer 95, as shown in FIG. The resulting twisted shape (distorted shape), wrinkles, etc. are also fixed by the adhesive layer 95, and the twisted shape, wrinkles, etc. are exposed as convex portions (convex shapes) on the outer surface of the skin member 90 via the adhesive layer 95. There were times when I would give it out. As a result, the appearance quality of a product (for example, an interior member, etc.) to which the skin member 90 is attached may be impaired.

The present invention has been made in view of the above-mentioned conventional problems, and its purpose is to prevent or suppress deterioration in the appearance quality of products due to twisted shapes, wrinkles, etc. that occur on the side edges of the skin.

The interior member 1 of Example 1 is an interior member 1 used in the cabin of an automobile, and is used, for example, in an instrument panel, garnish, or console box of an automobile. Further, the interior member 1 of the first embodiment includes a base member 10 having a predetermined shape depending on the installation location in the vehicle, and a skin member 20 that covers the base member 10 from the outside.

In addition, in the following description regarding the interior member 1, the vertical direction means the direction along the direction in which the skin member 20 approaches and separates from the base material part 10, for example, the same direction as the vertical direction in the paper of FIG. It is. In this case, the direction in which the skin member 20 approaches the base material part 10 is defined as the downward direction, and the direction in which the skin member 20 is spaced apart from the base material part 10 is defined as the upward direction. The left-right direction means a direction perpendicular to the up-down direction in a cross-sectional view when the skin member 20 is cut in a direction intersecting a stitched portion 32 (preferably perpendicular to the stitched portion 32), which will be described later. This is the same direction as the left and right direction in the paper of No. 1. Further, the left-right direction in the first embodiment and the second embodiment described later is a direction corresponding to the first direction defined in the claims. The front-rear direction means a direction perpendicular to the up-down direction and the left-right direction, and is, for example, the same direction as the front-back direction of the paper in FIG.

The base member 10 of the interior member 1 is made of synthetic resin and supports the attached skin member 20. The base member 10 has an outer surface 11 covered with a skin member 20 and a groove 12 recessed in the outer surface 11 . The concave groove portion 12 of the base material portion 10 is a part of the left and right skin side edges 23 (described later) of the skin member 20 (specifically, a folded edge 26 and a lower half of the bent portion 25 of the skin side edge 23). This is a part for accommodating and holding the skin member 20, and is provided corresponding to the position where the left and right skin side edges 23 of the skin member 20 are arranged. Further, a base material side adhesive layer 13 is provided on the outer surface 11 of the base material part 10. In the first embodiment, the base material-side adhesive layer 13 is provided corresponding to a portion where a second adhesive layer 42, which will be described later, is formed on the skin member 20.

In the present invention, the material, size, and shape of the base portion 10, the size and shape of the groove portion 12, and the material of the base-side adhesive layer 13 are not particularly limited. Moreover, the base material part 10 may be formed without providing the groove part 12 mentioned above, for example, and may be formed without providing the base material side adhesive layer 13.

In the interior member 1 of Example 1, the skin member 20 covers the base member 10 from the outside and is arranged such that a part of the skin member 20 is accommodated in the groove 12 of the base member 10. It is attached to the section 10. The skin member 20 includes two skin pieces 21 including a skin main body part 22 and a skin side edge 23, a suture part 31 for sewing together the two skin pieces 21, and an inner peripheral surface of the skin side edge 23 of the skin piece 21. It has a first adhesive layer 41 provided and a second adhesive layer 42 that fixes the skin main body part 22 of the skin piece 21 to the base material part 10.

In the first embodiment, of the two skin pieces 21 forming the skin member 20, the skin piece 21 disposed on one side (for example, the left side) in the left-right direction with respect to the sutured portion 31 is defined as the first skin piece 21a. However, the skin piece 21 disposed on the other side (for example, the right side) in the left-right direction is defined as a second skin piece 21b.

The first skin piece 21a and the second skin piece 21b are thinly formed of fabric such as cloth or leather such as synthetic leather. Further, the first skin piece 21a and the second skin piece 21b have a size and shape that can cover the base material part 10, and are flexible. The first skin piece 21a and the second skin piece 21b are sewn together by a seam portion 31. Furthermore, when the skin member 20 attached to the base material part 10 is viewed from above (see FIG. 2), there is one seam part (butt part) 32 between the first skin piece 21a and the second skin piece 21b. It is formed continuously like a line.

The first skin piece 21a and the second skin piece 21b of Example 1 are respectively a skin main body part 22 that covers the base material part 10 by being arranged along the outer surface 11 of the base material part 10, and a skin member The outer skin side edge portion 23 is bent into a substantially U-shape when viewed in a cross section (FIG. 1) intersecting the stitched portions 32 of the outer skin 20. In Example 1, the cross section of the skin member 20 that intersects with the stitched portion 32 (preferably, the cross section that is perpendicular to the stitched portion 32) can also be referred to as a cross section along the left-right direction (first direction). Furthermore, in the following description, the expression "cross-sectional view of the skin member 20" refers to a cross section of the skin member 20 that intersects with the stitched portion 32.

The skin side edge 23 of the first embodiment is integrally formed with the skin main body 22 and extends continuously from the skin main body 22 . Further, in a cross-sectional view of the skin member 20 (FIG. 1), the skin side edge portion 23 extends from the skin main body portion 22 in one direction in the left-right direction, and is further folded back in the other direction in the left-right direction to form a substantially U-shape. It is formed.

Such a substantially U-shaped epidermis side edge 23 includes a proximal end 24 that connects to the epidermal main body 22 and a bent part that extends from the proximal end 24 in a direction opposite to the epidermal main body 22 and is bent. 25, and a folded edge portion 26 that further extends from the bent portion 25 and overlaps the back side of the base end portion 24.

In this case, in a cross-sectional view of the skin member 20 (FIG. 1), for example, when a straight line extending in the vertical direction is imaginary from the position of the tip of the folded edge 26 on the skin side edge 23, the virtual straight line is The position where the straight line intersects with the skin piece 21 is defined as a boundary 27 between the skin main body 22 and the skin side edge 23 in the skin piece 21. Here, the tip of the folded edge 26 means the end of the folded edge 26 on the side opposite to the side connected to the bent part 25 in a cross-sectional view of the skin member 20 (FIG. 1).

In the first embodiment, the back surface of the skin member 20 and the back surface of the skin piece 21 refer to the first surface and the second surface of the skin member 20 and the skin piece 21 that are disposed on opposite sides of each other. means the surface facing or opposite. Further, the approximately U-shaped skin side edge portion 23 has an inner circumferential surface disposed on the inside and an outer circumferential surface facing outward in the cross-sectional view. In this case, the outer peripheral surface of the proximal end 24 at the skin side edge 23 forms a part of the surface (outer surface) exposed to the outside of the skin piece 21, and the folded edge 26 at the skin side edge 23 forms a part of the surface (outer surface) exposed to the outside of the skin piece 21. The outer circumferential surface becomes the back surface (inner surface) of the skin piece 21 facing the base material portion 10 .

In the first skin piece 21a and the second skin piece 21b of Example 1, the proximal end 24 of the skin side edge 23 extends inward in the left-right direction from the above-mentioned boundary 27 to the skin main body 22. It extends along the line. Here, the inner side in the left-right direction means the direction approaching the outer skin piece 21 of the other side to be sewn in the left-right direction.

The bent portion 25 of the epidermis side edge portion 23 extends downward from the edge of the proximal end portion 24 on the side opposite to the boundary portion 27 while curving so as to bulge inward in the left-right direction. . The folded edge 26 of the epidermis side edge 23 extends outward in the left-right direction from the edge of the bent portion 25 on the side opposite to the side connected to the proximal end 24, parallel to or approximately parallel to the proximal end 24. extending in parallel.

The stitching portion 31 is formed by sewing the first skin piece 21a and the second skin piece 21b together, and is also formed by a sewing thread that pierces and stitches the first skin piece 21a and the second skin piece 21b. has been done. In the first embodiment, in a plan view (FIG. 2) when the skin member 20 is viewed from above, the seam part 32 of the first skin piece 21a and the second skin piece 21b sewn together by the seam part 31 (in other words, the first The abutting portion 32) between the skin piece 21a and the second skin piece 21b is formed in a curved shape so as to curve in the left-right direction. As a result, on the back side of the skin member 20, for example, as shown in FIG. more likely to form.

The first adhesive layer 41 and the second adhesive layer 42 of the skin member 20 are formed by applying an adhesive to the skin piece 21. The first adhesive layer 41 of Example 1 is applied to a part of the inner circumferential surface of the proximal end 24 at the skin side edge 23, the entire inner circumferential surface of the bent portion 25, and the inner circumferential surface of the folded edge 26. It is provided on the entire surface. By providing the first adhesive layer 41 in this manner, the approximately U-shaped bent shape of the skin side edge portion 23 can be fixed.

Further, the inner circumferential surface of the proximal end portion 24 in the skin side edge portion 23 has a non-adhesive surface 45 on which the first adhesive layer 41 is not provided. In the first embodiment, the non-adhesive surface 45 provided on the proximal end 24 extends from the boundary 27 between the proximal end 24 and the skin main body 22 to the bent part in a cross-sectional view of the skin member 20 (FIG. 1). It extends continuously in the direction approaching 25. In this case, the non-adhesive surface 45 of the proximal end portion 24 is arranged within 50% of the entire inner peripheral surface of the proximal end portion 24, or within a slightly more than 50% range of the entire inner peripheral surface of the proximal end portion 24. .

Since such a non-adhesive surface 45 is provided at the base end 24 of the skin side edge 23, the folded edges 26 of the first skin piece 21a and the second skin piece 21b have a shape as shown in FIG. Even if a twisted shape 35, wrinkles, etc. occur, convex portions (convex shapes) caused by the twisted shape 35, wrinkles, etc. are formed on the outer surface of the skin member 20, especially at the proximal end of the skin side edge 23. It can be made difficult to expose the outer surface of the portion 24.

The second adhesive layer 42 of the first embodiment is provided on the back surface (inner surface) of the skin main body part 22 in order to fix the skin member 20 to the base material part 10. In Example 1, the second adhesive layer 42 only needs to be provided on at least a portion of the back surface of the skin main body portion 22, and the formation range of the second adhesive layer 42 is not limited.

In Example 1, the back surface of the skin main body portion 22 has a non-adhesive surface 45 on which the second adhesive layer 42 is not provided. In this case, the non-adhesive surface 45 of the skin main body 22 extends continuously from the boundary 27 between the skin main body 22 and the proximal end 24 in the direction away from the bent part 25, and It is formed continuously to the non-adhesive surface 45 of the end portion 24 mentioned above.

Since the non-adhesive surface 45 of the skin member 20 is continuously formed across the base end 24 of the skin side edge 23 and the skin main body part 22 via the boundary part 27 as described above, the skin The skin side edge 23 of the member 20 can be allowed to move slightly within the groove 12 of the base member 10 along the length of the groove 12. Thereby, the skin side edge 23 of the skin member 20 can be easily inserted and accommodated in the groove 12 along the shape of the groove 12. Furthermore, since the skin side edge 23 of the skin member 20 can be made less likely to be caught on the base member 10 within the groove 12, wrinkles etc. will not occur in the skin member 20 due to the skin member 20 being caught. can be suppressed.

Next, a method for manufacturing the skin member 20 of Example 1 will be described.
First, a first skin piece 21a and a second skin piece 21b cut into a desired shape are prepared. Subsequently, sewing is performed on the prepared first skin piece 21a and second skin piece 21b. By this sewing process, the sewing thread is pierced through the first skin piece 21a and the second skin piece 21b to form a sutured part 31 with the sewing thread, and the sutured part 31 is used to pierce the first skin piece 21a and the second skin piece 21b. Sew together the piece 21b.

Next, a masking 50 is formed as shown in FIG. A part of the skin piece 21b is covered. In this case, the masking 50 is formed on one surface of the skin piece 21 that forms the back surface of the skin main body portion 22 and the inner peripheral surface of the skin side edge portion 23 . Note that in the present invention, the method of forming the masking 50 is not particularly limited.

After forming the masking 50 on the first skin piece 21a and the second skin piece 21b, an adhesive layer 40 is formed by applying an adhesive to the one surface of the first skin piece 21a and the second skin piece 21b ( (see Figure 4). Further, after the adhesive layer 40 is formed, by peeling off the masking 50 from the first skin piece 21a and the second skin piece 21b, the adhesive layer 40 formed on the masking 50 is removed, so the first skin piece A non-adhesive surface 45 is formed on one surface of the second skin piece 21a and the second skin piece 21b. In this case, among the adhesive layers 40 formed on the first skin piece 21a and the second skin piece 21b, the adhesive layer 40 formed closer to the skin side edge 23 than the position of the non-adhesive surface 45 is the first adhesive layer 40 formed on the first skin piece 21a and the second skin piece 21b. The adhesive layer 40 formed on the opposite side of the skin side edge 23 from the position of the non-adhesive surface 45 becomes the second adhesive layer 42 .

Thereafter, the first skin piece 21a and the second skin piece 21b, on which the adhesive layer 40 and the non-adhesive surface 45 are formed, are each bent at the stitched part 31 to form the bent part 25, as shown in FIG. At the same time, the folded edge portion 26 extending from the bent portion 25 is overlapped with the base end portion 24. At this time, the first skin piece 21a and the second skin piece 21b are bent so that the adhesive layer 40 formed in the sutured part 31 and its surrounding area is wrapped inside, and the adhesive layers 40 are pasted together. It will be done.

By performing the above steps, a skin member 20 as shown in FIGS. 1 to 3 is produced.
Note that in the present invention, the method for manufacturing the skin member 20 is not particularly limited. For example, in the first embodiment, after the first skin piece 21a and the second skin piece 21b are sewn together at the stitching part 31, the adhesive layer 40 (first adhesive layer 41 and The skin member 20 is produced by forming the second adhesive layer 42). However, in the present invention, after forming the adhesive layer 40 on the first skin piece 21a and the second skin piece 21b, the first skin piece 21a provided with the adhesive layer 40 and the second skin piece 21b are sewn together at the stitching part 31. The skin member 20 may be produced by this.

The skin member 20 produced by performing the above steps is then attached to the base member 10 having a separately formed groove portion 12. At this time, as shown in FIG. 1, the skin member 20 covers the outer surface 11 of the base material part 10 with the skin main body part 22, and inserts the skin side edge part 23 into the groove part 12 of the base material part 10. In this way, it is attached to the base member 10. Further, by bonding the second adhesive layer 42 provided on the skin main body part 22 of the first skin piece 21a and the second skin piece 21b to the base material side adhesive layer 13 provided on the base material part 10, the skin main body part 22 is fixed to the base member 10. As a result, the interior member 1 of Example 1 in which the base member 10 is covered with the skin member 20 is manufactured.

In the interior member 1 of Example 1 manufactured as described above, the first adhesive layer 41 and the non-adhesive surface 45 are provided on each skin side edge 23 of the first skin piece 21a and the second skin piece 21b. ing. In particular, the non-adhesive surface 45 is provided in a range that is half of the inner peripheral surface of the proximal end portion 24 or in a range that slightly exceeds half of the inner peripheral surface of the proximal end portion 24 in a cross-sectional view of the skin member 20. (In other words, the non-adhesive surface 45 is provided over half or more of the inner circumferential surface of the proximal end portion 24).

Thereby, the substantially U-shaped bent shape of the skin side edge 23 can be stably maintained by the first adhesive layer 41. Furthermore, even if the folded edges 26 of the first skin piece 21a and the second skin piece 21b have a twisted shape 35 or wrinkles as shown in FIG. The wrinkles (particularly the twisted shape 35 and the outer ends of the wrinkles in the left and right direction) are difficult to be fixed to the proximal end 24 of the epidermis side edge 23 via the first adhesive layer 41, and the twisted shape 35 This makes it easier for wrinkles to disperse at the folded edge 26 of the epidermis side edge 23.

Therefore, convex portions (convex shapes) caused by the twisted shape 35 or wrinkles can be made difficult to appear on the surface (outer surface) serving as the designed surface of the skin member 20. As a result, it is possible to prevent or suppress deterioration of the appearance quality of the interior member 1, and therefore it is possible to stably provide the interior member 1 with good appearance or excellent appearance.

FIG. 6 is a sectional view schematically showing essential parts of the skin member of Example 2.
The skin member 60 of the second embodiment shown in FIG. It is attached by inserting and covering a part of the skin member 60 with the skin member 60 . By attaching the skin member 60 of the second embodiment to the base member 10 in this manner, an interior member similar to that of the first embodiment can be formed.

The skin member 60 of the second embodiment includes two skin pieces 61 (a first skin piece 61a and a second skin piece 61b) having a skin main body part 62 and a skin side edge part 63, and a first skin piece 61a and a second skin piece 61b. A stitching part 71 for sewing together the skin piece 61b, an adhesive layer 80 (first adhesive layer 81) provided on the inner peripheral surface of the skin side edge 63 of the skin piece 61, and decorative sewing formed on the skin side edge 63. 87.

The skin member 60 of Example 2 is formed without the second adhesive layer 42 provided on the skin main body 22 in the above-described Example 1, and the entire back surface of the skin main body 62 is formed on the non-adhesive surface 85. It is formed as. In the skin member 60 of the second embodiment, a second adhesive layer similar to that of the first embodiment described above may be formed on the back surface of the skin main body portion 62 of the skin member 60.

The first skin piece 61a, the second skin piece 61b, and the stitched part 71 of the second embodiment are substantially the same as the first skin piece 21a, the second skin piece 21b, and the stitched part 31 of the first embodiment described above. are formed in the same way. That is, the first skin piece 61a and the second skin piece 61b of Example 2 each have a skin main body part 62 and a substantially U-shaped skin side edge part 63. Further, the approximately U-shaped skin side edge portion 63 has a base end portion 64, a bent portion 65, and a folded edge portion 66.

The first adhesive layer 81 of the second embodiment is applied to a part of the inner peripheral surface of the proximal end 64 at the skin side edge 63, the entire inner peripheral surface of the bent portion 65, and the inner peripheral surface of the folded edge 66. The first adhesive layer 81 fixes the approximately U-shaped bent shape of the skin side edge 63.

The inner circumferential surface of the proximal end 64 and the inner circumferential surface of the folded edge 66 of the skin side edge 63 each have a non-adhesive surface 85 on which the first adhesive layer 81 is not provided. The non-adhesive surface 85 of the proximal end portion 64 is continuous from the boundary portion 67 between the proximal end portion 64 and the skin main body portion 62 in the direction approaching the bent portion 65 in the cross-sectional view of the skin member 60 (FIG. 6). It extends over 50% of the entire inner circumferential surface of the proximal end portion 64, or within a slightly more than 50% range of the entire inner circumferential surface of the proximal end portion 64. The non-adhesive surface 85 of the folded edge 66 extends continuously from the tip of the folded edge 66 in the direction approaching the bent part 65, and also covers 50% of the entire inner peripheral surface of the folded edge 66. or a little over 50% of the entire inner circumferential surface.

In the second embodiment, the non-adhesive surface 85 of the base end portion 64 and the non-adhesive surface 85 of the folded edge portion 66 are formed to have the same area or approximately the same area. Further, the non-adhesive surface 85 of the base end portion 64 and the non-adhesive surface 85 of the folded edge portion 66 are disposed such that the entire non-adhesive surface 85 faces each other in the vertical direction. By providing the non-adhesive surfaces 85 on both the proximal end 64 and the folded edge 66 in this manner, even if a shape or wrinkles are formed due to the folded edge 66 of the epidermis side edge 63, It is possible to more effectively prevent or suppress the appearance of convex portions (convex shapes) on the outer surface serving as the design surface of the skin member 60 due to the twisted shape or wrinkles.

In the present invention, when the non-adhesive surface 85 is provided on both the proximal end 64 and the folded edge 66 of the skin side edge 63, the non-adhesive surface 85 of the proximal end 64 and the non-adhesive surface 85 of the folded edge 66 are This means that the non-adhesive surfaces 85 may be arranged so as to face each other in the vertical direction in at least some regions, instead of facing each other in the vertical direction on the entire non-adhesive surface 85.

The decorative sewing part 87 of the second embodiment is formed so as to sew together the base end 64 of the outer skin side edge 63 and the folded edge 66. In this case, the decorative sewing part 87 is arranged at the center of the base end part 64 and the folded edge part 66 in the left-right direction. In the second embodiment, the folded edge 66 of the skin side edge 63 is formed long in the left-right direction so that both the part where the first adhesive layer 81 is formed and the part which becomes the non-adhesive surface 85 can be formed. . Since the folded edge 66 is formed to be long in the left-right direction in this way, sewing can be easily performed on the base end 64 of the skin side edge 63 and the folded edge 66. , the decorative sewing portion 87 can be stably formed.

By exposing the decorative sewing portion 87 on the outer surface of the skin member 60, the interior member to which the skin member 60 is attached can be decorated. Thereby, the design or decoration of the interior member can be improved, or a sense of luxury can be given to the interior member. Note that the forming position, forming range, forming method, etc. of the decorative sewing portion 87 are not particularly limited. Further, the skin member 60 may be formed without providing the decorative sewing part 87, for example, as in the first embodiment described above.

An interior member is manufactured by attaching the skin member 60 of the second embodiment as described above to the base member 10. In the interior member manufactured in this manner, a first adhesive layer 81 and a non-adhesive surface 85 are provided on each skin side edge 63 of the first skin piece 61a and the second skin piece 61b. Therefore, the approximately U-shaped bent shape of the skin side edge portion 63 can be stably maintained. At the same time, as described above, even if a shape or wrinkles are formed due to the folded edge 66 of the skin side edge 63, a convex portion is formed on the outer surface of the skin member 60 due to the twisted shape or wrinkles. Exposure can be more effectively prevented or suppressed. Therefore, by using the skin member 60 of Example 2, it is possible to prevent or suppress deterioration of the appearance quality of the interior member and provide an interior member with good appearance or excellent appearance. becomes.

In addition, in Example 1 and Example 2 described above, a part of the skin members 20, 60 (specifically, a part of the skin side edge parts 23, 63) is attached to the base material part 10 in which the groove part 12 is provided. The skin members 20 and 60 are attached to the base member 10 in such a manner that the skin members 20 and 60 are inserted and accommodated, and the skin members 20 and 60 are placed over the base member 10 . However, in the present invention, the base material portion may be formed without providing a groove portion for accommodating a part of the skin member. That is, the skin member of the present invention can be used by being attached to a base member formed with a structure that accommodates a part of the skin member, and can also be used by being attached to a base member formed with a structure that does not accommodate a part of the skin member. It is also possible to use it by attaching it to the section.

Furthermore, in the first and second embodiments described above, both the first skin pieces 21a, 61a and the second skin pieces 21b, 61b forming the skin members 20, 60 are provided with the first adhesive layers 41, 81. It has outer skin side edges 23, 63. However, the present invention is also applicable to a case where only one of the first skin piece and the second skin piece forming the skin member has a skin side edge portion provided with the first adhesive layer.
