The backboard 6 is three-dimensionally formed of a polyester or polyurethane foam material or the like.
Specifically, when the backboard 6 is addressed to the pad 4 from the side to be the rear surface 2f of the seatback 2, the rear side of the rear surface 2f of the seatback 2, the left side 2c, the upper surface 2d, and the right side 2e It is molded in three dimensions so that it can cover the part of The rear surface 2f of the seat back 2 is a surface opposite to the front surface 2a of the backrest surface, and is also referred to as a rear surface 2f.

Furthermore, the backboard 6 has a line fastener 7b (hereinafter simply referred to as a fastener 7b) which is an open fastener attached to the edge 6a on the front side.
The fastener 7b is coupled and separated (opened and closed) to the fastener 7a when the backboard 6 is applied to the pad 4 from the side to be the rear surface 2f. The fastener 7 a and the fastener 7 b are combined to form a fastener portion 7.
The position of the opening of the fastener, which is the starting point when joining the fastener 7a and the fastener 7b, is the position P1 or the position P4.

As shown in FIG. 2, the backboard 6 is attached with a hook receiving portion 8 b that locks the hook 8 a to the lower edge 6 b.
The hook receiving portion 8b is sewed on a weak press portion AS2 described later formed on the backboard 6 as described later. The weak press portion AS2 may be extended to include the bent portion of the edge 6b.
The hooks 8a and the hook receivers 8b may not be a pair extending in the left-right direction.
It may be a plurality of sets attached apart in the left-right direction.
Further, the pocket cover 41 is opened by non-sewing on the upper edge 41a side in the central portion of the backboard 6, and the left edge 41b, the lower edge 41c and the right edge 41d are sewn by sewing thread 36 Is attached by

When the trim cover 5 is put on the pad 4 from the front side and the backboard 6 is addressed from the rear side, the fastener 7a and the fastener 7b are closely opposed to each other.
Further, at the lower part of the rear surface 2f of the seat back 2, the hook 8a is hooked and locked to the hook receiving portion 8b.
Thus, the backboard 6 is integrated with the trim cover 5. That is, in the sheet 51, the backboard 6 is attached on the rear surface 2f side, which is the back surface of the seatback 2, as an appearance visible member.

  Next, a method of forming the backboard 6 and a method of attaching the fastener 7b and the hook receiving portion 8b and the pocket cover 41 to the backboard 6 will be described in detail with reference mainly to FIGS.

  In forming the backboard 6, a band sheet-like base material 6 c and a skin material 6 d are used. The backboard 6 hot presses the strip sheet intermediate 6T formed by the original sheet forming apparatus 10 shown in FIG. 5 using these as raw materials by the heating device 26 and the forming machine 27 shown in FIG. Furthermore, the unnecessary part of a periphery is cut | judged and formed with the cutting machine 28. FIG.

First, as shown in FIG. 5, in the original sheet forming apparatus 10, the band sheet-like base material 6c wound around the reel 11 is drawn out from the reel 11, and is drawn between the pair of rollers 12a and 12b rotating in pressure.
The lower part of the roller 12b is immersed in the adhesive 9 contained in the pool 9a.
Thus, the adhesive 9 is applied to one surface side (lower surface side in FIG. 5) of the base 6c.

On the other hand, a band sheet-like surface covering material 6d having the same width as that of the base 6c is wound around the reel 13.
The surface material 6 d is fed out from the reel 13, passes through the guide roller 15, and is drawn between the pair of rollers 14 and 14 a rotating in pressure.
Similarly, the base material 6c to which the adhesive 9 is applied is also drawn in such a manner that the surface to which the adhesive 9 is applied is the skin material 6d and the skin material 6d is overlapped between the pair of rollers 14 and 14a. .
Thereby, the base material 6c and the skin material 6d are overlapped with the adhesive 9 interposed therebetween.

And after carrying out from a pair of rollers 14 and 14a in the state where the base material 6c and the skin material 6d were piled up, it crosses over the drying rollers 16-20 sequentially, and it conveys.
As a result, the adhesive 9 is cured to form the adhesive layer 9b, and the base material 6c and the skin material 6d form the band sheet intermediate 6T integrated with the adhesive layer 9b interposed therebetween.

  Thereafter, the intermediate 6T is wound around the product reel 23 through the tension applying rollers 21 and 22.

Next, the product reel 23 around which the intermediate 6T is wound is loaded into the loading section 26a of the heating device 26, as shown in FIG.
The intermediate body 6T is unwound from the product reel 23 and is passed between a pair of rollers 25 and 25 rotating in pressure.
Furthermore, it passes between a pair of heaters 26b and 26b which are separately disposed facing each other in the vertical direction of FIG. The heater 26b is, for example, a ceramic heater.
The intermediate 6T is heated while passing between the heaters 26b and 26b, and is softened to such an extent that it can be easily deformed by an external force.

Next, the softened intermediate 6T is carried into the molding machine 27.
The molding machine 27 has a male die 27a and a female die 27b which are separated in the vertical direction of FIG.
The male mold 27a and the female mold 27b have surface shapes corresponding to the shape of the backboard 6 which is a product to be molded.
The molding machine 27 compresses and deforms the intermediate 6T which has entered between the male die 27a and the female die 27b in the vertical direction. Specifically, the intermediate body 6T is deformed into a three-dimensional shape and thickness according to the surface shape of each of the dies 27a and 27b and the minimum gap between the male die 27a and the female die 27b at the time of pressing.
In FIG. 6, a case is described in which the intermediate 6T is press-formed into a concavo-convex shape to form a formed intermediate 6T1.

  Finally, unnecessary portions of the formed intermediate 6T1 are cut by the cutter 28 to obtain the backboard 6 as a product.

In the molding machine 27, a plurality of minimum gaps between the male die 27a and the female die 27b at the time of pressing are set in accordance with the portion of the backboard 6 to be formed.
That is, the minimum gap between the male mold 27a and the female mold 27b at the time of pressing is a portion of a predetermined value (referred to as a strong mold pressing portion) and a portion wider (larger than the predetermined value) (referred to as a weak mold pressing portion) And at least two different gaps.

More specifically, the portion where intermediate 6T is pressed by the mold weak pressing portion (simply referred to as the weak pressing portion) is more base material than the portion pressed by the mold strong pressing portion (simply referred to as the strong pressing portion). The amount of compression of 6c is small, soft and thick. Conversely, the strong press portion has a larger amount of compression of the base 6c than the weak press portion, is hard (high rigidity, high hardness), and becomes a thin portion.
The weak press portion can be made soft enough to be sewn by making the gap of the mold weak press portion at the time of pressing wider than a certain degree.

  As a result, the mold strong press unit corresponds to the molding of the part (area) requiring high strength as the backboard 6, and the part (area) where the buffer effect is desired to be obtained, the part to be sewn (area), and the bendable By making the mold weak press part correspond to the part (area) to be formed, desired hardness and rigidity can be given to the backboard 6 for each area.

  Hereinafter, the strong press portion formed on the backboard 6 is referred to as a strong press portion AH, and the weak press portion is referred to as a weak press portion AS.

Thus, in the backboard 6, as shown in FIG. 7, the base material 6 c and the skin material 6 d are integrated with the cured adhesive layer 9 b interposed therebetween.
The backboard 6 is formed to have a strong press portion AH and a weak press portion AS which is thicker and softer than the strong press portion AH.

  Formation regions of the strong press portion AH and the weak press portion AS in the backboard 6 will be described with reference to FIGS. 1 to 4 and 8. In FIGS. 2 to 4, the adhesive layer 9 b is not shown in order to avoid complication of the drawing. FIG. 8 (a) is a front view of the central portion of the backboard 6, and FIG. 8 (b) is a perspective view of the portion shown in FIG. 8 (a) as viewed from the front upper left.

The backboard 6 has three independent weak press parts AS1 to AS3 as the weak press parts AS.
The weak press portion AS1 is continuously formed on the front edge 6a of the backboard 6 along the edge 6a. The weak press portion AS1 is formed at least at a portion (area) at which the fastener 7b is sewed on the edge 6a.
The weak press portion AS2 is continuously formed on the lower edge 6b of the backboard 6 along the edge 6b. The weak press portion AS2 is formed at least at a portion (area) at which the hook receiver 8b is sewed on the edge 6b.
The weak press portion AS2 may be extended so as to include a bent portion of the edge portion 6b from a portion where the hook receiver 8b is sewn.
In this case, the edge 6b can be bent at any time after molding.

The weak press portion AS3 corresponds to the weak press portion AS3a corresponding to the left edge 41b of the pocket cover 41 and the lower edge 41c as shown in FIGS. 3 and 4 and FIGS. 8A and 8B. And a weak press portion AS3c corresponding to the right edge portion 41d.
The weak press portion AS3 is formed as, for example, a mounting portion TK of the pocket cover 41 at a central portion of the backboard 6, for example.

Fig.8 (a) is a front view of the center part in the single-piece | unit of the backboard 6, FIG.8 (b) is the perspective view which looked at Fig.8 (a) from the front diagonal upper left.
The attachment portion TK which is the weak press portion AS3 having the weak press portions AS3a to AS3c is formed in, for example, a continuous U-shape as shown in FIG.
The backboard 6 is harder and more rigid than the mounting portion TK which is a weak pressing portion AS3 corresponding to the weak pressing portions AS1 and AS2 of the edge portions 6a and 6b and the pocket cover 41 and the weak pressing portion AS3 which is other portions. And a strong press part AH. The rigidity necessary for the backboard 6 is secured by having the strong press portion AH.

As shown in FIG. 2 and FIG. 4, the fastener 7 b is sewn on the weak press portion AS 1 at the edge portion 6 a by a thread 31 to form a folded portion 7 b 1.
Further, as shown in FIG. 2, the hook receiver 8 b is sewn on the weak press portion AS 2 at the edge 6 b by the sewing thread 34.
Further, as shown in FIGS. 3 and 4, the pocket cover 41 is sewn to the attachment portion TK, which is the weak press portion AS3 provided at the central portion of the backboard 6, by the sewing thread 36.

As described above in detail, the seat 51 of the first embodiment does not need to have holes for screwing in the backboard 6. In addition, the step of forming a dedicated shape for supporting the hook portion on the backboard 6 is not required independently.
Therefore, the sheet 51 can be formed while suppressing the cost increase.

Also, the backboard 6 and the trim cover 5 can be integrated by the engagement of the fasteners 7a and 7b.
The positions at which the fasteners 7a and the fasteners 7b are engaged are at positions where the left side surface 2c, the upper surface 2d and the right side surface 2e of the seat 51 are easily visible.
Thereby, the work of attaching the backboard 6 is very easy.

Further, since the pocket cover 41 is sewn to the attachment portion TK of the backboard 6, it can be attached in the same sewing process as the fasteners 7a and 7b.
As a result, the step of attaching the pocket cover 41 to the backboard 6 with screws or hooks is not necessary other than the sewing step.
Therefore, according to the pocket structure of the seat back 2 in the sheet 51, the pocket PK can be formed at low cost by sewing the pocket cover 41 to the backboard 6.

  The present invention is not limited to the embodiments described above, and various modifications can be made without departing from the scope of the present invention.

  The shape of the weak press portion AS3 formed on the backboard 6 is not limited to the above continuous U-shape. For example, as shown in FIG. 9, the weak press portions AS3a and AS3c corresponding to the left edge 41b and the right edge 41d are respectively divided into a plurality in the vertical direction, and the weak press AS3 and the strong press in the vertical direction AH may be alternately formed. FIG. 9 is a diagram corresponding to FIG. 8 (a).

FIG. 9 shows an example in which the weak press portions AS3a and AS3c are respectively divided at two places, and the divided portion is a strong press portion AH.
As a result, since the strong pressing portion AH intervenes in the portion of the backboard 6 at which the pocket cover 41 is sewn, the sewn portion of the pocket cover 41 in the backboard 6 is less likely to be deformed, and the heavier in the pocket PK. Will be able to accommodate

A range of the backboard 6 facing the accommodation space Va is referred to as a range ARa (see FIGS. 3 and 8).
The range ARa is a rectangular range surrounded by the weakly pressed portions AS3a to AS3c, as indicated by hatching in FIG. 8 (b).
As shown in FIG. 10, the backboard 6 is hard and thin with a higher degree of compression than the weak press portion AS3 and soft and thick with a lower degree of compression than the strong press portion AH, as shown in FIG. You may deform | transform into the backboard 6A made into the intermediate | middle press part AM.
FIG. 10 is a perspective sectional view of the backboard 6A in the sheet 51A, cut at the S3-S3 position in FIG.
A sheet having a backboard 6A in place of the backboard 6 is referred to as a sheet 51A (see parenthesized reference numerals in FIG. 1). As shown in FIG. 1, the appearance is the same as the sheet 51.

The intermediate press portion AM is the minimum gap between the male die 27a and the female die 27b when the backboard 6 is press molded, and the minimum gap value between the strong mold portion and the minimum gap value of the weak mold portion. It can be obtained by setting it to any value of.
That is, the intermediate press portion AM is a portion set so that the compression amount, the rigidity, the hardness, and the thickness are between the strong press portion AH and the weak press portion AS.
By forming the range ARa as the intermediate press portion AM, the content contained in the storage space Va of the pocket PK can be supported with an appropriate degree of softness without deformation of the backboard 6.

When the portion of the range ARa of the backboard 6 is formed hard as the strong press portion AH, the stored matter is easily crushed, and when the stored matter is forcibly pushed into the storage space Va, the portion of the range ARa is deformed hard Because it is difficult, there is a possibility that the stored product side may be deformed.
Therefore, when the portion of the range ARa is softly formed as the weak press portion AS, the portion including the sewn pocket cover 41 becomes a soft portion.
Therefore, in the case of a heavy object or a pointed object contained in the housing space Va, there is no possibility of causing plastic deformation such as distortion or denting on the backboard 6 side.

Since the range ARa of the sheet 51A, which is a modified example, is the intermediate press portion AM, the intermediate press portion AM is more flexible than the strong press portion AH, even if the easily crushable container is pushed into the accommodation space Va. Therefore, the force is absorbed and dispersed better, and the deformation of the contents is suppressed.
In addition, even if the content stored in the storage space Va is heavy or sharp, the intermediate press portion AM in the range ARa has higher rigidity and higher surface hardness than the weak press portion AS. Therefore, it is hard to produce deformation such as distortion or dent.
Thereby, the usability of the pocket PK formed by attaching the pocket cover 41 becomes better.

  Since the intermediate press portion AM can be formed by press forming the backboard 6A, the cost increase due to this does not substantially occur. Therefore, according to the pocket structure having the intermediate press portion AM and the sheet provided with the same, a user-friendly pocket can be obtained at low cost.

  The installation range and the shape of the intermediate press portion AM in the modification may be appropriately set in accordance with the shape of the pocket cover 41, the shape of the backboard 6, and the like.

It may be a sheet 52 described below as a modification of the sheet 51.
The seat 52 has a backboard 66 and a pocket cover 71 in place of the backboard 6 and the pocket cover 41 in the seat 51.
FIG. 11 is a perspective partial assembly view of a central portion of backboard 66 for illustrating attachment of pocket cover 71 to backboard 66, and is a view comparable to FIG. FIG. 11 also shows a general perspective view of the pocket cover 71 before attachment.

The back board 66 is basically formed entirely of the weak press portion AS, and the region requiring high rigidity is a strong press portion AH.
Pocket cover 71 is provided with folding portions 71b1 to 71d1 at left edge 71b, lower edge 71c, and right edge 71d, and a plurality of through holes 71e are formed at appropriate intervals including folding portions 71b1 to 71d1. ing.

The U-shaped attachment portion 66 a corresponding to the folding portions 71 b 1 to 71 d 1 in the backboard 66 is a strong press portion AH. The mounting portion 66a is formed with a plurality of holes 66b corresponding to the plurality of through holes 71e.
A rectangular range ARb (corresponding to the range ARa in the backboard 6) surrounded by the attachment portion 66a is an intermediate press portion AM.

In this configuration, the pocket cover 71 passes, for example, a rivet 72 formed of resin from the rear side through the through hole 71 e of the pocket cover 71 and the hole 66 b of the backboard 66 and pushes the push nut 73 against the shaft projecting forward. It is attached to the backboard 66 by fitting and fixing.
Since the mounting portion 66 a is formed as the strong pressing portion AH, the pocket cover 71 is firmly attached to the backboard 66 by the rivet 72 and the push nut 73.

An example of the range for forming the strong press portion AH on the backboard 66 of the sheet 52 is shown in FIG.
FIG. 12 shows a substantially rectangular range ARc including the portion to which the pocket cover 71 is attached on the front surface 66c which is the back side of the backboard 66, and an overhanging range ARd and a range overhanging to the left and right at the top of the range ARc. ARe is considered to be a strong press part AH. The range ARf other than the range ARc to ARe is a weak press portion AS or an intermediate press portion AM.

  The attachment of the pocket cover 71 to the backboard 66 may be performed by heat-welding a shaft projecting forward of the resin rivet 72 without using the push nut 73.

According to the sheet 52 of the modification, the backboard 66 is entirely formed by the weak press portion AS or the intermediate press portion AM, and a range including the attachment range of the pocket cover 71 and a high rigidity is required. It is made of
Thereby, the backboard 66 exerts a certain degree of buffer effect as a whole, and can accommodate various contents in the pocket PK. Therefore, the seat 52 may be used, for example, as a front seat when the seats are arranged side by side.
