(1. Applicable target)
A foamed molded article is formed by filling the inside of a bag-like skin body with a foamed member. A pocket is formed on the outside of the skin by sewing the pocket skin member onto the skin. The pocket skin member is directly or indirectly integrated with the foam member by utilizing the fact that the foam member is fixed to the skin body as the foam member is molded.

Here, the foamed molded product is applied to, for example, armrests, headrests, footrests, and the like. Examples of the armrest include a side armrest that is rotatably provided on the side of the seat, a center armrest that is rotatably provided in the center of the seat, and an armrest that is fixed to the side or center of the seat. Further, the armrest includes an upper armrest in an armrest console box. Here, in the armrest, the pocket skin member can be provided on the side surface, the front surface, or the bottom surface. In the headrest, the pocket skin member is provided on the side or back surface. In the footrest, the pocket skin member is provided on the side surface or the like.

(2. First example)
(2-1. Basic configuration of armrest 10)
The basic configuration of a first example of an armrest 10 as an example of a foam molded product will be described with reference to FIG. For example, the armrest 10 is attached to a side surface of a seat back (not shown) of a vehicle so as to be rotatable around a predetermined rotation axis. As shown in FIG. 1, the armrest 10 is formed, for example, in an elongated shape. In FIG. 1, the front left side of the figure is the front side, and the back right side of the figure is the rear side. That is, the armrest 10 shown in FIG. 1 is provided rotatably around the rear part.

The armrest 10 includes a bag-shaped skin body 20 and a foam member 40 injected into the skin body 20. The armrest 10 includes a core material (not shown) inside the skin body 20. The core material is integrally fixed to the foam member 40 inside the skin body 20.

As shown in FIG. 1, the surface of the skin body 20 includes a first side surface 31, a second side surface 32, and a peripheral surface 33. The first side surface 31 is generally formed in a planar shape, but may be formed in a gently curved three-dimensional shape. The second side surface 32 is a surface opposite to the first side surface 31 and is generally formed in a planar shape, but may be formed in a gently curved three-dimensional shape. Here, the plane shape is not limited to a physically perfect plane, but is used in the sense of allowing a slight curved surface.

The circumferential surface 33 is a surface connecting the entire circumference of the edge of the first side surface 31 and the entire circumference of the edge of the second side surface 32, and is formed in a three-dimensional shape approximating an elliptical cylinder shape. That is, the peripheral surface 33 constitutes the upper surface and the lower surface of the armrest 10. Note that the peripheral surface 33 may be replaced with a shape similar to an elliptical cylinder shape, and may be formed in a polygonal cylinder shape such as a square cylinder shape.

The skin body 20 is formed into a bag shape by sewing the edges of one or more body skin pieces 21-26. In the first example, the skin body 20 is formed by a plurality of body skin pieces 21-26. That is, the skin body 20 includes body skin pieces 21, 22, 23 corresponding to the first side 31, body skin pieces 24 corresponding to the second side 32, and body skin pieces 25, 26 corresponding to the peripheral surface 33. It is formed. Although the main body skin pieces 25 and 26 corresponding to the peripheral surface 33 are formed as separate pieces, they may be formed as one piece.

Note that the number of body skin pieces for forming the skin body 20 can be set arbitrarily. Further, the skin body 20 may be formed of one body skin piece. In this case, one main body skin piece develops, for example, a bag-like three-dimensional shape and has an inward bending allowance.

Here, the boundary between the first side surface 31 and the circumferential surface 33 constitutes a corner 34 whose radius of curvature is equal to or less than a predetermined value, which is a sufficiently smaller value than the surrounding area. Further, the boundary between the second side surface 32 and the circumferential surface 33 similarly constitutes a corner portion 34 . That is, each of the first side surface 31, the second side surface 32, and the peripheral surface 33 constitutes a surface partitioned by the corner portion 34. In particular, the first side surface 31 and the second side surface 32 constitute a surface surrounded by the corner 34.

Hereinafter, the surface defined by the corner portion 34 whose radius of curvature is less than or equal to a predetermined value will be referred to as a constituent surface. In the first example, the skin body 20 has a plurality of constituent surfaces 31, 32, and 33. These constituent surfaces 31, 32, and 33 constitute a planar shape or a three-dimensional shape. In other words, the corner 34 is a boundary between the adjacent constituent surfaces 31, 32, and 33, and is a portion where the radius of curvature changes greatly relative to the range of change in the radius of curvature of the constituent surfaces 31, 32, and 33. be. The corner portion 34 only needs to have a radius of curvature Rc of a predetermined value or less, and may be formed by a portion where one body skin piece is bent, or a portion where a plurality of body skin pieces 22 and 25 are sewn. may be formed. Note that the predetermined value of the radius of curvature Rc is set to, for example, 30 mm or 20 mm. In the first example, the predetermined value of the radius of curvature Rc is approximately 10 mm.

Further, the skin body 20 has an opening (not shown). The opening is used for inserting a core material (not shown) into the skin 20, turning the skin 20 inside out after sewing, and injecting raw materials for the foamed member 40. Note that the core material is formed of, for example, hard resin, soft resin (including elastomer), rubber, metal, or the like. The core material is used to connect the seat back and the armrest 10, etc. The opening is provided at any position on the skin body 20. For example, the opening can be provided at the center of any of the constituent surfaces 31, 32, 33, or at the corner 34.

The foam member 40 is a foam made of urethane or the like. The raw material for the foamed member 40 is injected into the skin 20 and is foamed inside the skin 20, so that the foamed member 40 is filled inside the skin 20. Here, by foaming the raw material inside the skin body 20, the foamed member 40 covers the outside of the core material and is fixed to the body skin pieces 21-26.

The armrest 10 also includes a pocket Pk outside the skin body 20. In the first example, the constituent surface 31 of the plurality of constituent surfaces 31, 32, and 33 of the skin body 20 is the surface that forms the pocket Pk. The constituent surface 31 on which the pocket Pk is formed is referred to as the target epidermis constituent surface 31. The target epidermis forming surface 31 is adjacent to the circumferential surface 33 of the armrest 10 via the corner 34 .

The armrest 10 includes a pocket skin member 50 that forms a pocket Pk on the outside of the skin body 20. In the first example, the pocket skin member 50 is composed of only one pocket skin piece 51 formed of a material sheet. A part of the edge of the pocket skin member 50, specifically, the edge of the pocket skin member 50 located on a side other than the top surface, is sewn to the skin body 20. Then, on the outside of the skin body 20, a pocket Pk that opens upward in FIG. 1 is formed.

Here, in FIG. 1, the longitudinal direction of the armrest 10 is defined as a first direction L1. The opening of the pocket Pk is positioned upward in a posture of the armrest 10 in which the longitudinal direction of the armrest 10 coincides with the front-rear direction. Therefore, the direction from the opening of the pocket Pk toward the bottom (vertical direction in FIG. 1) corresponds to the second direction L2, which is a direction orthogonal to the first direction L1. Further, the first direction L1 corresponds to a direction (approximately the left-right direction in FIG. 1) that intersects the direction from the opening of the pocket Pk toward the bottom.

(2-2. Skin piece used for skin body 20 and pocket skin member 50)
The skin pieces used for the skin body 20 and the pocket skin member 50 will be described with reference to FIGS. 2 and 3. As shown in FIG. 2, the skin body 20 is composed of a plurality of body skin pieces 21-26, and the pocket skin member 50 is composed of one pocket skin piece 51. Here, the main body skin pieces 21-26 and the pocket skin pieces 51 are made of the same material sheet 90.

The material sheet 90 has a laminated structure including a skin sheet 91, a slab sheet 92, and a film 93, as shown in FIG. The skin sheet 91 is made of, for example, fabric or synthetic leather, and forms the outer surface. The slab sheet 92 is made of, for example, slab urethane foam and has flexibility. The slab sheet 92 is laminated on the back surface of the skin sheet 91. The film 93 is made of resin and is laminated on the back surface of the slab sheet 92.

Here, when the material of the foamed member 40 is absorbed into the slab sheet 92, the hardness of the absorbed portion of the slab sheet 92 increases and the flexibility decreases. Therefore, the film 93 is used for the purpose of preventing the slab sheet 92 from absorbing the raw material of the foamed member 40. Therefore, the raw material of the foamed member 40 is not absorbed into the slab sheet 92 in the region where the film 93 is arranged. However, since the material sheet 90 has a laminated structure of a skin sheet 91, a slab sheet 92, and a film 93, the film 93 is not disposed at the end of the slab sheet 92, so the slab sheet 92 is exposed. That is, absorption of the raw material of the foamed member 40 is allowed at the end of the slab sheet 92.

(2-3. Detailed configuration of epidermal body 20)
The detailed structure of the skin body 20 will be explained with reference to FIGS. 1 and 2. In the plural body skin pieces 21-26 constituting the skin body 20 shown in FIG. 2, the parts to be sewn are shown by broken lines. In the body skin pieces 21-26, the portion inside the broken line forms a design surface, and the portion outside the broken line forms a bending allowance. The plurality of body skin pieces 21-26 are integrally connected by sewing with the skin sheet 91 facing back and the bending allowances of the respective edges 21a-26a overlapping each other to form a bag-shaped skin body. 20 is formed. The skin body 20 is turned over so that the skin sheet 91 is the front surface.

When the raw material for the foamed member 40 is injected into the skin 20 and the foamed member 40 is foamed into a predetermined shape, the skin 20 is formed into the shape shown in FIG. The first, second, and third body skin pieces 21-23 form a generally planar target skin-constituting surface 31 (first side surface 31). In other words, the first side surface 31 formed by the three body skin pieces 21-23 constitutes the target skin forming surface 31 on which the pocket Pk is formed. On the target skin forming surface 31, the first body skin piece 21, the second body skin piece 22, and the third body skin piece 23 are arranged side by side in the first direction L1.

Further, the sewn portion 35A (shown in FIG. 1) of the first body skin piece 21 and the second body skin piece 22 is formed in a straight line parallel to the second direction L2. Further, the sewn portions 35B of the second body skin piece 22 and the third body skin piece 23 are also formed in a straight line parallel to the second direction L2. However, the sewing parts 35A and 35B are not limited to straight lines parallel to the second direction L2, but can be arbitrary lines such as curved lines and bent lines.

The body skin piece 24 is located on the opposite side from the target skin forming surface 31 and forms a substantially planar forming surface 32 (second side surface 32). Furthermore, the main body skin pieces 25 and 26 form an elliptical cylindrical constituent surface 33 (peripheral surface 33). The main body skin piece 25 forms the lower surface side of the constituent surface 33 (peripheral surface 33), and the main body skin piece 26 forms the upper surface side of the constituent surface 33 (peripheral surface 33). Each of the constituent surfaces 31, 32, and 33 is partitioned by two annular corners 34.

(2-4. Detailed configuration of pocket structure)
The detailed configuration of the pocket structure, which is the portion forming the pocket Pk, will be described with reference to FIGS. 2 and 4 to 6. The pocket structure includes a target skin forming surface 31 in the skin body 20 and a pocket skin member 50. The target epidermis constituent surface 31 is as described above.

In the first example, the pocket skin member 50 is formed of one pocket skin piece 51. Here, the pocket skin piece 51 has a first edge 51a located on one side in the first direction L1, a second edge 51b located on the other side in the first direction L1, and a bottom end located on the bottom in the second direction L2. It has an edge 51c and an upper edge 51d located at the upper part in the second direction L2.

Here, in the first example, the pocket skin member 50 is the same as the pocket skin piece 51, but as shown in the example below, there are cases where the pocket skin member 50 has a piece other than the pocket skin piece 51. Therefore, the edge of the pocket skin member 50 is defined as follows. That is, the pocket skin member 50 has a first end edge 61 located on one side in the first direction L1, a second end edge 62 located on the other side in the first direction L1, and a bottom edge located on the bottom in the second direction L2. 63, and an upper edge 64 located at the upper part in the second direction L2.

However, in the first example, the pocket skin member 50 is formed of one pocket skin piece 51. Therefore, in the first example, the first edge 51a, the second edge 51b, the bottom edge 51c, and the upper edge 51d of the pocket skin piece 51 are the first edge 61 of the entire pocket skin member 50, Coinciding with the second edge 62, the bottom edge 63 and the top edge 64. Hereinafter, in order to distinguish, the first edge 51a, the second edge 51b, the bottom edge 51c, and the upper edge 51d of the pocket skin piece 51 are referred to as the first edge 51a, the second edge 51b, and the second edge 51b, respectively. They are referred to as a bottom edge 51c and a top edge 51d.

Further, the pocket skin piece 51 has a double structure in which the material sheet 90 is folded back at the upper end edge 51d, and the folded surfaces of the film 93 face each other. This prevents the film 93 from being exposed on both the outer and inner surfaces of the pocket Pk formed by the pocket skin piece 51 on the target skin forming surface 31. That is, the skin sheet 91 of the pocket skin piece 51 forms the outer surface and the inner surface of the pocket Pk.

Further, in the pocket skin piece 51 shown in FIG. 2, the part inside the broken line indicating the part to be sewn forms a designed surface, and the part outside the broken line forms a bending allowance. At least a portion of the pocket skin piece 51 is sewn onto the target skin forming surface 31. In the first example, as shown in FIG. 4, in the pocket skin piece 51, a first end edge 51a and a second end edge 51b are sewn to the target skin forming surface 31.

Specifically, as shown in FIGS. 4 and 5, the entire length of the first end edge 51a of the pocket skin piece 51 is the same as the sewing part 35A between the first body skin piece 21 and the second body skin piece 22. It is folded into the inside of the skin body 20. Then, the entire length of the first end edge 51a is sewn onto the skin body 20 by sewing the end edges 21a and 22a of the first body skin piece 21 and the second body skin piece 22 together. Note that instead of sewing the entire length of the first edge 51 a to the skin 20 , only a part of the first edge 51 a may be sewn to the skin 20 .

Further, as shown in FIG. 5, the first end edge 51a projects inward from the inner surface of the skin body 20 at the sewn portion 35A of the first body skin piece 21 and the second body skin piece 22. Then, the foam member 40 is injected into the inside of the skin body 20. Therefore, the first end edge 51a is fixed to the foam member 40 while protruding inward from the inner surface of the skin body 20.

Thereby, the piece first edge 51a (equal to the first edge 61) that constitutes a part of the edge of the pocket skin piece 51 prevents the formation position of the pocket Pk from shifting and maintains the shape of the pocket Pk. The first reinforcing member 61a functions as the first reinforcing member 61a. Further, since the pocket skin piece 51 has a folded double structure, the first edge 51a of the piece serving as the first reinforcing member 61a is spread out in a V-shape as shown in FIG. and stick to it. Therefore, reinforcing force increases.

Further, the pocket skin piece 51 is formed of the material sheet 90, as described above. A slab sheet 92 is exposed at the end of the material sheet 90. Since the end of the first edge 51a serving as the first reinforcing member 61a protrudes inward of the skin body 20, it exists in a state where it easily contacts the foamed member 40. Therefore, when the raw material for the foamed member 40 is injected into the skin 20, it is absorbed into the slab sheet 92 at the end of the first edge 51a. Thereby, the first edge 51a of the first reinforcing member 61a is integrated with the foamed member 40.

Further, as shown in FIG. 4, the entire length of the second end edge 51b of the pocket skin piece 51 is inside the skin body 20 at the sewn portion 35B of the second body skin piece 22 and the third body skin piece 23. folded into. The entire length of the second end edge 51b is sewn onto the skin body 20 by sewing the edges 22a and 23a of the second body skin piece 22 and the third body skin piece 23 together. Note that the entire length of the second end edge 51b may not be sewn onto the skin body 20, but only a portion of the second end edge 51b may be sewn onto the skin body 20.

At this time, like the first edge 51a, the second end edge 51b is fixed to the foamed member 40 in a state in which it protrudes inward from the inner surface of the skin body 20 at the sewn portion 35B. In this way, the piece second edge 51b (equal to the second edge 62) that constitutes a part of the edge of the pocket skin piece 51 functions as the second reinforcing member 62a. Further, the second end edge 51b serving as the second reinforcing member 62a is fixed to the foam member 40 in a V-shaped expanded state. Further, the second end edge 51b serving as the second reinforcing member 62a is integrated with the foam member 40 by absorbing the foam member 40 into the slab sheet 92. Therefore, the second end edge 51b serving as the second reinforcing member 62a is more firmly fixed to the foamed member 40.

Further, at least a portion of the pocket skin piece 51 is sewn to the corner 34 of the target skin forming surface 31 and the other forming surface 33. In the first example, as shown in FIGS. 2 and 4, one bottom edge 51c is sewn to the corner 34 that is the boundary between the target skin forming surface 31 and the forming surface 33.

Specifically, as shown in FIGS. 4 and 6, the entire length of one bottom edge 51c of the pocket skin piece 51 located at the bottom of the pocket Pk is the same as the sewing part 35C between the main body skin piece 22 and the main body skin piece 25. It is folded into the inside of the skin body 20. Then, the entire length of the single bottom edge 51c is sewn to the skin body 20 by sewing the edges 22a and 25a of the body skin piece 22 and the body skin piece 25 together. Note that instead of sewing the entire length of the single bottom edge 51c to the skin body 20, only a part of the single bottom edge 51c may be sewn to the skin body 20.

Further, as shown in FIG. 6, the single bottom edge 51c projects inward from the inner surface of the skin body 20 at the sewn portion 35C between the second body skin piece 22 and the body skin piece 25. Then, the foam member 40 is injected into the inside of the skin body 20. Therefore, the single bottom edge 51c is fixed to the foamed member 40 while protruding from the inner surface of the skin 20. As a result, the single bottom edge 51c (equal to the bottom edge 63) constituting a part of the edge of the pocket skin piece 51 serves as a bottom edge that prevents the formation position of the pocket Pk from shifting and maintains the shape of the pocket Pk. It functions as a reinforcing member 63a.

Furthermore, since the pocket skin piece 51 has a double structure folded back at the top edge 51d, the bottom edge 51c serving as the bottom reinforcing member 63a is in a V-shaped expanded state as shown in FIG. Then, it is fixed to the foam member 40. Therefore, reinforcing force increases. Furthermore, the single bottom edge 51c as the bottom reinforcing member 63a is integrated with the foamed member 40 as the foamed member 40 is absorbed into the slab sheet 92. Therefore, the single bottom edge 51c serving as the bottom reinforcing member 63a is more firmly fixed to the foamed member 40.

As described above, the first reinforcing member 61a, the second reinforcing member 62a, and the bottom reinforcing member 63a all constitute a part of the pocket skin member 50, and constitute the reinforcing member 60a (see FIG. 2). Therefore, the pocket skin member 50 is integrally fixed to the skin body 20 by the reinforcing member 60a.

(2-5. Manufacturing method)
A method for manufacturing the armrest 10 will be explained. First, the edges 21a-26a of each body skin piece 21-26 are sewn with the skin sheet 91 of the body skin piece 21-26 facing inside (body sewing process).

At this time, the pocket skin piece 51 constituting the pocket skin member 50 is sewn together with the body skin pieces 21, 22, 23, and 25, with the pocket skin piece 51 overlapped with the surface of the body skin piece 22 on the skin sheet 91 side ( pocket sewing process). Specifically, the first edge 51a of the pocket skin piece 51 is overlapped with the edge 21a of the first body skin piece 21 and the edge 22a of the second body skin piece 22, and these are sewn simultaneously. . Further, the second edge 51b of the pocket skin piece 51 is overlapped with the edge 22a of the second body skin piece 22 and the edge 23a of the third body skin piece 23, and these are sewn simultaneously. One bottom edge 51c of the pocket skin piece 51 is overlapped with the edge 22a of the second body skin piece 22 and the edge 25a of the body skin piece 25, and these are sewn simultaneously.

Subsequently, each main body skin piece 21-26 is turned over so that the skin sheet 91 in each main body skin piece 21-26 faces outward (front-back reversal step). At this time, each body skin piece 21-26 can be turned over by using an opening (not shown) formed in any one of the body skin pieces 21-26. Subsequently, a core material (not shown) is inserted through an opening (not shown) in the skin body 20 (core material insertion step).

Subsequently, the raw material for the foamed member 40 is injected into the interior of the skin body 20 from an opening (not shown) in the skin body 20 (foamed raw material injection step). By foaming the raw material inside the skin 20, the foaming pressure brings the skin 20 into close contact with the inner surface of the foam mold. Then, the foam member 40 is fixed to the inner surface of the skin body 20. Further, the foam member 40 is fixed to the first reinforcing member 61a, the second reinforcing member 62a, and the bottom reinforcing member 63a that constitute the reinforcing member 60a.

(2-6. Effect)
The armrest 10 of the first example has a reinforcing member 60a (including a first reinforcing member 61a, a second reinforcing member 62a, and a bottom reinforcing member 63a) that sticks to the foam member 40 while protruding inward from the inner surface of the skin body 20. Equipped with According to such a configuration, the pocket skin member 50 forming the pocket Pk is directly integrated with the foam member 40 by fixing the reinforcing member 60a to the foam member 40. In this way, the reinforcing member 60a forming a part of the pocket skin member 50 makes it difficult for the formation position of the pocket Pk to shift. Therefore, it is possible to improve the accuracy of the formation position of the pocket Pk, and to maintain the shape of the pocket Pk during use.

(3. Second example)
In the armrest 10 of the first example, in the pocket skin piece 51 constituting the pocket skin member 50, the first piece edge 51a and the piece second edge 51b are the body skin pieces 21, 22 that constitute the target skin forming surface 31. , 23 at the sewing parts 35A and 35B of the parts 35A and 35B.

In addition to this, the following may be used. In the pocket skin piece 51 constituting the pocket skin member 50, the first end edge 51a of the pocket skin piece 51 is sewn together with the first edge 51a folded inside at the sewing part 35A, thereby forming the first reinforcing member 61a. On the other hand, the second end edge 51b may be sewn on the surface of the target skin-constituting surface 31 without being folded inward at the sewing portion 35B. In this case, the second edge 51b does not constitute the second reinforcing member 62a. Moreover, the first edge 51a and the second edge 51b may be opposite to each other. That is, the first end edge 51a of the piece may not constitute the first reinforcing member 61a, but the second end edge 51b of the piece may constitute the second reinforcing member 62a.

In the pocket skin piece 51, one bottom edge 51c is sewn to the corner 34 that is the boundary between the target skin forming surface 31 and the forming surface 33, as in the first example. Therefore, the single bottom edge 51c constitutes the bottom edge 63 of the pocket skin member 50, and functions as a bottom reinforcing member 63a. However, in the pocket skin piece 51, the first edge 51a and the second edge 51b are not sewn to the target skin forming surface 31.

The first elastic piece 52 is connected to the first end edge 51a of the pocket skin piece 51 by sewing. Furthermore, in the first elastic piece 52, the side opposite to the side connected to the pocket skin piece 51 constitutes a first edge 61 of the entire pocket skin member 50, and is sewn to the skin body 20.

Specifically, the second elastic piece 53 is folded into the sewing part 35B of the two adjacent main body skin pieces 22 and 23 on the target skin forming surface 31, and the skin body is sewn by sewing the end edges 22a and 23a together. 20 is sewn. Therefore, the second elastic piece 53 functions as the second reinforcing member 62a. In other words, the second elastic piece 53 is fixed to the foamed member 40 while protruding inward from the inner surface of the skin body 20 .

As described above, the first elastic piece 52 functions as the first reinforcing member 61a, the second elastic piece 53 functions as the second reinforcing member 62a, and the one bottom edge 51c of the pocket skin piece 51 functions as the bottom reinforcing member 63a. do. Therefore, the position and shape of pocket Pk are maintained. Furthermore, elastic deformation of the first elastic piece 52 and the second elastic piece 53 makes it possible to increase the capacity of the pocket Pk.

(5. Fourth example)
A fourth example of the armrest 10 will be described with reference to FIG. 9. The armrest 10 of the fourth example has a configuration in which the pocket skin member 50 also includes an elastic piece at the bottom, unlike the third example.

It has not been. The first elastic piece 52 and the second elastic piece 53 are similar to the armrest 10 of the third example.

The bottom elastic piece 54 is made of a material having a lower elastic modulus than the pocket skin piece 51. The bottom elastic piece 54 is made of, for example, rubber or elastomer and is formed into a band or string shape. The bottom elastic piece 54 may be one elastic piece or two or more elastic pieces. When there are two or more elastic pieces 54, the bottom elastic pieces 54 are arranged side by side in the first direction L1.

The bottom elastic piece 54 is connected to one bottom edge 51c of the pocket skin piece 51 by sewing in the second direction L2. Furthermore, the side of the bottom elastic piece 54 opposite to the side connected to the pocket skin piece 51 constitutes the bottom edge 63 of the entire pocket skin member 50 and is sewn to the skin body 20 . Specifically, the bottom elastic piece 54 is folded into the sewn portion 35C of the second body skin piece 22 and the body skin piece 25 adjacent to each other at the corner 34, and the skin body is sewn by sewing the end edges 22a and 25a together. 20 is sewn.

A seventh example of the armrest 10 will be described with reference to FIG. 12. As shown in FIG. 12, the target skin forming surface 31 of the skin body 20 has three body skin pieces 21-23 arranged in the first direction L1 as in the first example, and as in the sixth example. Similarly, the fourth main body skin piece 27 is arranged in the second direction L2 with respect to the second main body skin piece 22. Furthermore, the pocket skin member 50 is composed of only one pocket skin piece 51.

The first edge 51a of the pocket skin piece 51 is folded into the sewn portion 35A of the body skin pieces 21 and 22, and is sewn to the skin body 20 by sewing the edges of the body skin pieces 21 and 22 together. Further, the second edge 51b of the pocket skin piece 51 is folded into the sewn portion 35B of the body skin pieces 22 and 23, and is sewn to the skin body 20 by sewing the edges of the body skin pieces 22 and 23 together. .

Further, a second elastic piece 53 functioning as the second reinforcing member 62a may be provided. Furthermore, like the armrest 10 of the third example, a bottom elastic piece 54 functioning as a bottom reinforcing member 63a may be provided.

(9. Eighth example)
An eighth example of armrest 110 will be described with reference to FIGS. 13 and 14. The armrest 110 includes a skin body 120, a pocket skin member 150, and a reinforcing member 170. The skin body 120 includes a body skin piece 121 in which the three body skin pieces 21, 22, and 23 in the skin body 20 of the first example are combined into one body skin piece 121. That is, the skin body 120 is constituted by the body skin piece 121 shown in FIG. 13 and the body skin pieces 24-26 shown in FIG. 2. The surface formed by one body skin piece 121 constitutes the target skin forming surface 31 on which the pocket Pk is formed. However, the target skin forming surface 31 may be formed by a plurality of body skin pieces 21-23, as in the first example.

The pocket skin member 150 includes a pocket skin piece 51. As described in the first example, the pocket skin piece 51 has a first edge 51a, a second edge 51b, a bottom edge 51c, and a top edge 51d. In the pocket skin piece 51, the first edge 51a, the second edge 51b, and the bottom edge 51c are sewn on the outer surface of the center region 36 of the main body skin piece 121. Here, the central region 36 means a region that is not the sewn portion between the edges of the plurality of body skin pieces.

Further, in the eighth example, the pocket skin member 150 is formed of only one pocket skin piece 51. Therefore, in the eighth example, the first edge 51a, the second edge 51b, the bottom edge 51c, and the upper edge 51d of the pocket skin member 51 are the first edges of the entire pocket skin member 50, respectively. Coincident with edge 61 , second edge 62 , bottom edge 63 and top edge 64 .

However, like the armrest 10 of the second and third examples, the pocket skin member 150 includes, in addition to the pocket skin piece 51, at least one of the first elastic piece 52, the second elastic piece 53, and the bottom elastic piece 54. may be provided. In this case, the first edge 61, second edge 62, and bottom edge 63 of the entire pocket skin member 150 are constituted by the first elastic piece 52, the second elastic piece 53, the bottom elastic piece 54, and the like. In other words, the first edge 61, second edge 62, and bottom edge 63 of the entire pocket skin member 50 are sewn to the central region 36 of the surface of one body skin piece 121 on the outer surface. .

The reinforcing member 170 is formed of a separate member from the skin body 120 and the pocket skin member 150. The reinforcing member 170 is, for example, a band-shaped member. The reinforcing member 170 may be formed from the same material as the main body skin piece 121, or may be formed from a different material. When forming from the same kind of material, preparation of the material becomes easy.

Furthermore, the reinforcing member 170 is preferably made of a material that can absorb the raw material of the foamed member 40. For example, when the reinforcing member 170 is formed of the material sheet 90, the foamed member 40 can be absorbed into the slab sheet 92 at the end. Of course, even if the reinforcing member 170 is made of different materials, it is possible for the reinforcing member 170 to absorb the raw material of the foamed member 40. On the contrary, the reinforcing member 170 may be made of a material suitable for preventing leakage of the foam member to the outside, or may be made of a material cheaper than the main body skin piece 121.

The reinforcing member 170 is arranged on the back surface of the main body skin piece 121, as shown in FIG. Here, the reinforcing member 170 includes a first reinforcing member 171, a second reinforcing member 172, and a bottom reinforcing member 173. The first reinforcing member 171, the second reinforcing member 172, and the bottom reinforcing member 173 may be an integral member or may be separate members.

The first reinforcing member 171 is laminated on the main body skin piece 121 and the first end edge 61 of the pocket skin member 150. That is, the first reinforcing member 171 is arranged along the first edge 61. As shown in FIG. 14, the first reinforcing member 171 is sewn to the main body skin piece 121 and the first end edge 61 by sewing the main body skin piece 121 and the first end edge 61 together.

As shown in FIG. 14, in the first reinforcing member 171, the portions other than the portions sewn to the main body skin piece 121 and the first end edge 61 protrude inwardly from the inner surface of the skin body 120, and the foamed member 40 and stick to it. Therefore, the first reinforcing member 171 prevents the pocket skin member 150 from being displaced at the first end edge 61. In particular, when the first reinforcing member 171 is sewn at the center in the width direction, the first reinforcing member 171 is fixed to the foamed member 40 in a V-shaped expanded state. This increases reinforcing force.

The second reinforcing member 172 is laminated with the main body skin piece 121 and the second end edge 62 of the pocket skin member 150. That is, the second reinforcing member 172 is arranged along the second edge 62. Like the first reinforcing member 171, the second reinforcing member 172 is sewn to the main body skin piece 121 and the second end edge 62 by sewing the main body skin piece 121 and the second end edge 62 together.

Further, the bottom reinforcing member 173 is laminated with the main body skin piece 121 and the bottom edge 63 of the pocket skin member 150. That is, the bottom reinforcing member 173 is arranged along the bottom edge 63. Like the first reinforcing member 171, the bottom reinforcing member 173 is sewn to the main body skin piece 121 and the bottom edge 63 by sewing the main body skin piece 121 and the bottom edge 63 together.

Therefore, the first reinforcing member 171, the second reinforcing member 172, and the bottom reinforcing member 173 are fixed to the foamed member 40 on the back surface of the main body skin piece 121 in a state in which they protrude inward from the inner surface of the skin body 120. Thereby, the position and shape of the pocket Pk are suitably maintained. Further, the pocket Pk can be placed at any position in the central region 36 of the surface of the main body skin piece 21. In this way, even if the pocket Pk is placed at an arbitrary position, the position and shape of the pocket Pk are maintained by the reinforcing member 170.

(10. Others)
In the above, the main body skin pieces 21-27 and the pocket skin members 50, 150 are formed of a material sheet 90 including a skin sheet 91, a slab sheet 92, and a film 93. On the other hand, the body skin pieces 21-27 and the pocket skin members 50, 150 may be made of various materials.

For example, the material sheet of the pocket skin members 50, 150 may have a two-layer structure of a skin sheet 91 and a slab sheet 92. Even with the structure without the film 93 as described above, depending on the combination of the type of material of the slab sheet 92 and the type of raw material of the foamed member 40, absorption of the foamed member 40 into the slab sheet 92 may be suppressed. can.
