Description

[Technical Field]

[0001] The present invention relates to a vehicle seat having a storage portion into which other members can be inserted and held. [Background technology]

[0002] Patent Document 1 discloses technology related to this type of vehicle seat. The seating assembly (vehicle seat) disclosed in Patent Document 1 includes a seat cushion that serves as a seating portion and a seat back that stands up from the rear of the seat cushion. A band-shaped strap is provided on the rear surface of the seat back so as to extend in the seat width direction. Both ends of this strap in the seat width direction are fixed to a trim (cover portion) that forms the outer surface of the seat back. The strap also has areas (attachment areas) sewn to the trim with seams that are formed at equal intervals in the seat width direction. The strap and trim can be expanded into a loop between adjacent seams, allowing other members to be inserted and held in the loop-shaped portion. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] U.S. Patent No. 1,148,5292 Summary of the Invention [Problem to be solved by the invention]

[0004] In the above-described technology, both ends of the strap in the seat width direction are fixed to the trim. As shown in Figures 2 and 4A of Patent Document 1, this fixing method involves placing the strap against the trim (cover portion) and fixing both ends of the strap to the trim with a stitching line. However, in the above-described configuration, a stitching line for attaching the strap is required in addition to the stitching portion (existing configuration) already provided in the trim, which increases the cost of the seat. The present invention was devised in light of the above-described points, and the problem to be solved by the present invention is to attach the strap to the cover portion while suppressing an increase in the cost of the seat. [Means for solving the problem]

[0005] As a means for solving the above problems, a vehicle seat according to a first aspect of the present invention includes a cover portion that forms the exterior of the seat and a belt-shaped strap attached to the cover portion, and a storage portion that can hold and insert other components between the cover portion and the strap. In this type of seat configuration, it is desirable to be able to attach the strap to the cover portion while suppressing increases in seat costs. Therefore, in the cover portion of the present invention, first and second seams, which are the points where adjacent cover pieces are sewn together, are formed so as to extend in the same direction. The strap is then sewn across the first and second seams that extend in the same direction, with one end of the strap sewn to the first seam and the other end of the strap opposite the first end sewn to the second seam. In this invention, the strap is attached by sewing to both seams that are existing components of the cover portion, which contributes to suppressing increases in seat costs.

[0006] The vehicle seat of the second invention is the vehicle seat of the first invention, which is provided with an opening adjustment part that adjusts the size of the opening of the storage compartment by partially bringing the cover part and the strap into close contact with each other. In this invention, the opening adjustment part functions to adjust the size of the opening of the storage compartment regardless of the distance between the two seams.

[0007] A vehicle seat according to a third aspect of the present invention is the vehicle seat according to the second aspect of the present invention, wherein the opening adjustment portion extends from at least one of the first seam and the second seam toward the storage portion. In this invention, the other member to be inserted into the storage portion can be guided toward the storage portion by moving it along the opening adjustment portion. [Effects of the Invention]

[0008] According to the first aspect of the present invention, the strap can be attached to the cover portion while suppressing an increase in the cost of the seat. According to the second aspect of the present invention, the strap can be attached to the cover portion with better performance. And according to the third aspect of the present invention, the strap can be attached to the cover portion with even better performance. [Brief explanation of the drawings]

[0010] Hereinafter, embodiments of the present invention will be described with reference to Figures 1 to 17. In each figure, arrows indicating the front-rear direction, the up-down direction (height direction), and the left-right direction (seat width direction) of the vehicle seat are appropriately illustrated. Note that in each figure, for convenience, other members inserted into the storage section are illustrated by two-dot dashed lines, but this is not intended to limit the configuration (type, shape, size, etc.) of these other members.

[0011] [Vehicle seat overview] First, an overview of a vehicle seat 2 shown in Figures 1 and 2 will be described. In this vehicle seat 2, the lower part of a seat back 6 is connected to the rear part of a seat cushion 4, which serves as the seating portion, via a recliner (not shown). The seat back 6 is a member against which the occupant rests, and is formed in a vertically long rectangular shape. The seat back 6 is covered by a seat cover 10, which defines its exterior, covering a seat frame 6F that forms the framework of the seat and a seat pad 6P that elastically supports the occupant.

[0012] Here, a seating portion 6A on which an occupant can sit is formed in the center of the front of the seat back 6 shown in Figure 2, extending in the vertical direction of the seat. Furthermore, on both sides (right and left) of the seat back 6A in the seat width direction, a bank portion 6B is provided that protrudes toward the seating side, and the side surfaces of this bank portion 6B form left and right gusset portions 6C (for convenience, in Figure 2, the left bank portion and gusset portion are given the corresponding reference numerals, and the right bank portion and gusset surface are given the corresponding reference numerals in parentheses). The rear surface 6D of the seat back 6 shown in Figure 1 has an upper side exposed to the outside, and a substantially rectangular lower pocket 25 integrally formed on the lower side. The lower end and left and right ends of this lower pocket 25 are sewn closed to the seat cover 10, so that the upper end can be opened and closed.

[0013] 1, first straps 51 to fourth straps 54 are attached to a seat cover portion (rear cover region 20, described later) on the rear surface 6D of the seat back 6. Referring to FIGS. 1 and 3, the rear surface 6D of the seat back 6 is formed with a plurality of storage compartments 60 that can be expanded into loops by the rear cover region 20 and the straps. In the above-described configuration, the storage compartments 60 are configured to hold various other components (including supplies and accessories), thereby enabling the vehicle seat 2 to be retrofitted with other components. In this type of configuration, it is desirable to be able to attach the straps while suppressing an increase in the cost of the seat. Therefore, in this embodiment, the straps are attached to the rear cover region 20 using a configuration described later while suppressing an increase in the cost of the seat. The configuration of the vehicle seat 2 will be described in detail below, in the order of the basic configuration of the seat cover 10, the configurations of the first straps 51 to fourth straps 54, and the method of attachment.

[0014] [Basic configuration of seat cover] The seat cover 10 shown in Figures 1 and 2 is a bag-shaped surface material that forms the exterior of a seat and can be made of fabric (woven fabric, knitted fabric, nonwoven fabric) or leather (natural leather, artificial leather). The seat cover 10 has cover portions that form the front (sitting surface), rear, left and right surfaces, top and bottom surfaces. Referring to Figure 4, adjacent cover portions can be sewn together with institches S1 that have a predetermined strength (for convenience, all institches are given the same reference numeral in each figure). Furthermore, when the cover portion is formed from multiple cover pieces, adjacent cover pieces can also be sewn together with the institches S1.

[0015] 4, the seat cover 10 has a seating surface cover portion 11 that forms the front surface (seating surface) and a rear surface cover portion 20 (described later) that are arranged facing each other with an appropriate gap between them (in FIG. 4 and other figures, each cover piece that forms the rear surface cover portion is enclosed in parentheses with a reference symbol indicating the rear surface cover portion). A lower surface cover portion 12 that forms the lower surface is sewn to the lower end of the seating surface cover portion 11. An upper surface cover portion 13 that forms the upper surface is sewn across and connected to the upper ends of the seating surface cover portion 11 and the rear surface cover portion 20. Also, referring to FIG. 5, the seat cover 10 has gusset cover portions 14 that form left and right gusset portions 6C (for convenience, only the left gusset cover portion is shown in FIG. 5). The left and right seat cover portions 14 are respectively connected between the seat cover portion 11 and the rear cover portion 20 and connected to these cover portions by stitching or fasteners.

[0016] [Rear cover part of the seat cover] 4 and 5, the rear cover region 20 is formed by sewing together a first cover piece 21 to a fourth cover piece 24, etc. (For convenience, FIG. 5 shows the cover pieces inside the lower pockets in a perspective view). The first cover piece 21 to the fourth cover piece 24 are arranged in this order (numerical order) from the top to the bottom of the seat. The lower pocket 25 is also sewn together and integrated with the rear cover region 20, so that the lower pocket 25 also forms part of the rear cover region 20 and defines the exterior of the seat. The first cover piece 21 to the fourth cover piece 24 are each formed to extend in the seat width direction, and their left and right edges are connected to the above-mentioned hem cover region 14. The fourth cover piece 24 has a lower end cover region 26, which includes a band 27, connected to its lower end, and is configured to be hung on the seat frame via the lower end cover region 26 (see FIG. 5).

[0017] 4 and 5, a first cover piece 21 and a second cover piece 22 are arranged above the rear cover portion 20 to form the seat outer surface (appearance). The first cover piece 21 is arranged at the top, and its upper end is sewn and connected to the top cover portion 13. The first cover piece 21 is smaller in vertical dimension than the second cover piece 22 below it, and is formed in a strip shape extending in the seat width direction. Referring to FIGS. 1 and 6, an upper first seam 31, which serves as a sewn connection point between the first cover piece 21 and the top cover portion 13, is formed so as to extend in the seat width direction. Furthermore, an upper second seam 32, which serves as a sewn connection point between the first cover piece 21 and the second cover piece 22, is formed so as to extend in the seat width direction, i.e., in the same direction as the upper first seam 31. The upper first sewn portion 31 and the upper second sewn portion 32 are portions that are provided in advance on the rear cover portion 20 side, and are existing components of the rear cover portion 20. The distance between the upper first sewn portion 31 and the upper second sewn portion 32 can be determined by the vertical dimensions of the first cover piece 21. Note that, while "extending in the same direction" as described above means that it is desirable for both sewn portions to extend in the same direction in a substantially straight line (parallel) as shown in the drawings, it is acceptable for one of the sewn portions to be inclined or bent relative to the other as long as a strap, which will be described later, can be attached thereto.

[0018] 4 and 5, the third cover piece 23 and the fourth cover piece 24 are arranged at the bottom of the rear cover portion 20 so as to overlap with the lower pocket 25. When the lower pocket 25 is opened, the third cover piece 23 and the fourth cover piece 24 are exposed to the outside and form the exterior of the seat. The third cover piece 23 is smaller in vertical dimensions than the second cover piece 22 above it and the fourth cover piece 24 below it, and is formed in a strip shape extending in the seat width direction. A lower first seam 41, which serves as a sewn connection point between the second cover piece 22 and the third cover piece 23, is formed so as to extend in the seat width direction. A lower second seam 42, which serves as a sewn connection point between the third cover piece 23 and the fourth cover piece 24, is formed so as to extend in the seat width direction, i.e., in the same direction as the lower first seam 41. The lower first sewn portion 41 and the lower second sewn portion 42 are portions that are provided in advance on the rear cover portion 20 side, and are existing components of the rear cover portion 20. The distance between the lower first sewn portion 41 and the lower second sewn portion 42 can be determined by the vertical dimensions of the third cover piece 23.

[0019] [strap] Next, a first strap 51, a second strap 52, a third strap 53, and a fourth strap 54 are attached to the rear cover region 20 shown in FIGS. 1 and 5 so as to be exposed to the outside. Each of the first strap 51 to the fourth strap 54 is formed in a strip shape extending vertically. The first strap 51 and the second strap 52 are disposed at the upper part of the rear cover region 20, i.e., at a position overlapping with the first cover piece 21 described above. The first strap 51 is disposed to the left of the first cover piece 21, and the second strap 52 is disposed to the right of the first cover piece 21. The third strap 53 and the fourth strap 54 are disposed at the lower part of the rear cover region 20, i.e., at a position overlapping with the third cover piece 23 described above. The third strap 53 is disposed to the left of the third cover piece 23, and the fourth strap 54 is disposed to the right of the third cover piece 23. Furthermore, in this embodiment, the left-right distance between the first strap 51 and the second strap 52 is approximately the same as the left-right distance between the third strap 53 and the fourth strap 54.

[0020] [Containment section] 1 and 5, the first strap 51 to the fourth strap 54 and the first cover piece 21 or the third cover piece 23 are configured so that at least a portion thereof can be expanded into a loop shape. For example, referring to FIGS. 3 and 6, the upper and lower ends and the upper side of the first strap 51 are connected to the rear cover portion 20 by sewing or the like (described in detail later), but the lower side is not sewn to the first cover piece 21. Therefore, the lower part of the first strap 51 moves rearward away from the first cover piece 21 when an external force is applied. As a result, a loop-shaped storage section 60 is formed between the lower part of the first strap 51 and the first cover piece 21, into which another member can be inserted and stored. This storage section 60 is formed to extend laterally, and has openings 61 at its left and right ends, respectively, so that another member can be inserted and stored therein (in FIG. 3, etc., the reference numeral corresponding to the opening on the left side is given, and the reference numeral corresponding to the opening on the right side is given in parentheses).

[0021] 1 and 5, the first strap 51 to the fourth strap 54 form storage compartments 60 at approximately the four corners of the upper side of the rear cover portion 20 (in each drawing, the storage compartment formed by the first strap 51 is denoted by a reference symbol, and the storage compartments formed by the other straps are denoted by corresponding reference symbols in parentheses). In the above-described configuration, a mounting device 100 such as a carabiner (an example of an other member) can be inserted into and held in each storage compartment 60. Various items such as a substantially rectangular table 101 can be attached to the seat back 6 via each mounting device 100. It is also possible to store various other members in at least one of the storage compartments 60.

[0022] [Strap material] The materials of the first strap 51 to the fourth strap 54 shown in FIG. 5 are not particularly limited, but can be selected taking into consideration their placement positions, etc. For example, the first strap 51 and the second strap 52 can be formed of the same material as the rear cover portion 20 or a different material, and can be formed of a strong woven webbing material. The third strap 53 and the fourth strap 54, together with the lower part of the rear cover portion 20, cover the lower pocket 25 in the closed state. In such a case, the third strap 53 and the fourth strap 54 can be formed of the same material as the third strap 53 and the fourth strap 54, and can typically be formed of a fabric such as a woven fabric or a knitted fabric. This minimizes the feeling of a foreign body sensation even if the occupant comes into contact with the third strap 53 or the fourth strap 54 when using the lower pocket 25.

[0023] [Attaching the strap] Then, the first strap 51 to the fourth strap 54 are attached to the rear cover portion 20 shown in FIGS. 1 and 5 . In this type of attachment work, it is desirable to minimize unnecessary stitching to minimize seat cost increases. Therefore, the rear cover portion 20 is formed with first and second stitched portions (such as the upper first stitched portion 31 and the upper second stitched portion 32) at which adjacent cover pieces are sewn together, extending in the same direction. The straps (such as the first strap 51) are sewn across the first and second stitched portions, which extend in the same direction, with one end of the strap sewn to the first stitched portion and the other end of the strap sewn to the second stitched portion. According to the above-described configuration, the straps are attached by sewing together both of the existing stitched portions of the rear cover portion 20, which contributes to reducing seat cost increases. Hereinafter, the attachment method will be described in detail using the first strap 51 and the third strap 53 as an example.

[0024] 3 and 5, the upper part of the rear cover part 20 has an upper first sewn portion 31 and an upper second sewn portion 32, which are existing components, provided to extend in the seat width direction (the same direction). A first strap 51 is disposed so as to be overlapped on the first cover piece 21 and to be stretched between the upper first sewn portion 31 and the upper second sewn portion 32. As shown in FIG. 6, the upper end (one end) of the first strap 51 is sewn together with the upper first sewn portion 31, i.e., the first cover piece 21 and the upper cover part 13 are sewn together via an institch portion S1. The lower end (the other end) of the first strap 51 is sewn together with the upper second sewn portion 32, i.e., the first cover piece 21 and the second cover piece 22 are sewn together via an institch portion S1. The second strap 52 is also sewn together with the rear cover part 20, similar to the first strap 51. In the above-described configuration, the first strap 51 and the second strap 52 are attached by sewing them together between the two existing seams of the rear cover portion 20. This allows the first strap 51 and the second strap 52 to be attached simultaneously with sewing the rear cover portion 20, eliminating the need for a seam for attaching the straps. Therefore, with the above-described configuration, the first strap 51 and the second strap 52 can be attached to the rear cover portion 20 while suppressing an increase in the cost of the seat.

[0025] Next, referring to Figures 5 and 7, the lower part of the rear cover portion 20 also has the existing first lower seam 41 and second lower seam 42 extending in the seat width direction. The third strap 53 is placed between the first lower seam 41 and the second lower seam 42 while overlapping the third cover piece 23. The upper end of the third strap 53 is sewn to the first lower seam 41, i.e., the second cover piece 22 and the third cover piece 23 are sewn together via an institch S1. The lower end of the third strap 53 is sewn to the second lower seam 42, i.e., the third cover piece 23 and the fourth cover piece 24 are sewn together via an institch S1. In the case of the third strap 53 made of fabric, folding back the upper and lower ends and sewing them together reduces the risk of fraying at the ends. The fourth strap 54 is also sewn to the rear cover portion 20, like the third strap 53. Even with the above-described configuration, the third strap 53 and the fourth strap 54 can be attached to the rear cover portion 20 while suppressing an increase in the cost of the seat. Furthermore, with the above-described configuration, the third strap 53 and the fourth strap 54 are hidden by the lower pocket 25 in the closed state, making it possible to prevent the straps from being unintentionally exposed to the outside.

[0026] [Aperture adjustment part] 1 and 3, the first strap 51 to the fourth strap 54 can be provided with an opening adjustment portion 70 that adjusts the opening size of the storage section 60. For example, taking the first strap 51 shown in FIG. 3 as an example, the first strap 51 has a stitched portion 71 that extends vertically as the opening adjustment portion 70. The stitched portion 71 as the opening adjustment portion 70 sews and connects the upper portion of the first strap 51 and the first cover piece 21 to tightly fit them together. In this way, the opening adjustment portion 70 functions to partially tightly fit the first strap 51 and the first cover piece 21, thereby making it possible to adjust the opening size of the storage section 60 to be narrower or narrower.

[0027] Furthermore, the opening adjustment portion 70 shown in Fig. 3 is formed to extend in the vertical direction, extending from the upper first sewn portion 31 toward the storage portion 60. As a result, a guide region 80 that guides the other member toward the storage portion 60 is formed in the first strap 51 by the opening adjustment portion 70, adjacent to the storage portion 60. According to the above-mentioned configuration, as shown in Fig. 8, the other member to be held (the wearing device 100 in Fig. 8) can be inserted shallowly into the guide region 80, for example, and moved from top to bottom along the opening adjustment portion 70. Therefore, the other member to be held can be smoothly guided toward the storage portion 60, facilitating the insertion of the other member even if the opening of the storage portion 60 is narrow.

[0028] As described above, in this embodiment, the first strap 51 to the fourth strap 54 are attached by co-sewing to both seamed portions that are existing components of the rear cover region 20, which contributes to suppressing increases in seat costs. Furthermore, in this embodiment, the opening adjustment portion 70 functions to adjust the opening size of the storage portion 60 regardless of the distance between the two seamed portions. In this embodiment, other members to be inserted into the storage portion 60 can be guided toward the storage portion 60 by moving them along the opening adjustment portion 70.

[0029] [Variations] Here, the straps may have various configurations in addition to those described above. Therefore, the following describes modified straps, taking the first strap as an example. First, the first strap 51A of Modification 1 shown in FIG. 9 is provided with a left stitched portion 71A, a right stitched portion 71B, and a lower stitched portion 71C as a first opening adjustment portion 70A. The left stitched portion 71A and the right stitched portion 71B extend from the upper first sewn portion 31 toward the storage compartment 60 with an appropriate lateral spacing. The lower stitched portion 71C, which extends laterally, is connected to the lower ends of the left and right stitched portions. According to the above configuration, the first opening adjustment portion 70A formed by multiple stitched portions functions to more reliably bring the first strap 51A and the first cover piece 21 into close contact with each other, thereby more reliably adjusting the opening size of the storage compartment 60. In the above-described configuration, for example, the left stitch portion 71A can be gradually inclined inward (to the right in FIG. 9) as it approaches the bottom (see the imaginary inclined line 710 indicated by the two-dot dashed line in FIG. 9 and its inclination angle θ). By forming at least one of the left stitch portion 71A and the right stitch portion 71B in an inclined shape, other components can be guided more smoothly toward the storage section 60.

[0030] The height of the storage compartment can be changed as needed. For example, in a first strap 51B of Modification 2 shown in FIG. 10 , a left lower stitched portion 72A and a right lower stitched portion 72B serving as a second opening adjustment portion 70B are formed from the upper second sewn portion 32 toward the storage compartment 60, thereby increasing the height of the storage compartment 60. In a first strap 51C of Modification 3 shown in FIG. 11 , an upper stitched portion 73A is formed from the upper first sewn portion 31 toward the storage compartment 60. A lower stitched portion 73B is formed from the upper second sewn portion 32 toward the storage compartment 60. In Modification 3, a third opening adjustment portion 70C is formed from the upper stitched portion 73A and the lower stitched portion 73B, thereby increasing the height of the storage compartment 60 to a level higher than that of Example 1 and lower than that of Modification 2.

[0031] The extension direction of the storage compartment can be changed as needed. For example, in the first strap 51D of Modification 4 shown in FIG. 12, the fourth opening adjustment section 70D includes a row of multiple upper stitches (upper row 74A) aligned in the seat width direction and a row of multiple lower stitches (lower row 74B) aligned in the seat width direction (for convenience, in FIG. 12, each upper stitch is labeled with a symbol indicating its row, and each lower stitch is labeled with a symbol indicating its row). In the upper row 74A, the length of the upper stitches gradually decreases from left to right, while in the lower row 74B, the length of the lower stitches gradually increases from left to right. In this way, in Modification 4, by adjusting the length of each stitch as the fourth opening adjustment section 70D, the storage compartment 60 can be formed to extend diagonally (the extension direction of the storage compartment is indicated by the arrow X1 in FIG. 12). The storage compartment can also be formed to slope downward to the right, in addition to the downward slope shown in FIG. 12. Furthermore, when storing other components such as a round carabiner, the storage section can be formed in a curved shape.

[0032] In the fifth modified example shown in FIG. 13, the seat cover 10 is provided with a first left-side sewn portion 31X and a second right-side sewn portion 32X that extend vertically, and a first strap 51E is disposed between the left and right sewn portions in the seat width direction. The first strap 51E of the fifth modified example has a vertically aligned row of left stitched portions (left-side row 75A) and a vertically aligned row of right stitched portions (right-side row 75B) (for convenience, in FIG. 13, each left stitched portion is labeled with a symbol indicating its row, and each right stitched portion is labeled with a symbol indicating its row). In the left-side row 75A, each left stitched portion extends from the first left-side sewn portion 31X toward the storage compartment 60, and in the right-side row 75B, each right stitched portion extends from the second right-side sewn portion 32X toward the storage compartment 60. According to the above-mentioned configuration, the stitch portions that form the fifth opening adjustment portion 70E function to form a storage portion 60 with the desired opening dimensions that extends vertically (in Figure 13, the direction in which the storage portion extends is indicated by arrow X2).

[0033] The opening adjustment portion can be formed with various structures other than stitching. For example, a first strap 51F of Modification 6 shown in FIG. 14 has a hook-and-loop fastener structure 76 as a sixth opening adjustment portion 70F. A first strap 51G of Modification 7 shown in FIG. 15 has a pair of left and right point fastener structures 77, 78 as a seventh opening adjustment portion 70G. According to Modifications 6 and 7, the opening size of the storage portion 60 can be adjusted to a larger size by opening each fastener structure as needed. A first strap 51H of Modification 8 shown in FIG. 16 has a band 90 as an eighth opening adjustment portion 70H attached to the first cover piece 21 and extending across the first strap 51H. In Modification 8, storage portions 60 can be provided on both the upper and lower sides of the band 90 (for convenience, the upper storage portion is designated by a reference numeral, and the lower storage portion is designated by a reference numeral in parentheses in FIG. 16). Furthermore, the first strap 51G and the band 90 may be made of the same material or different materials. For example, if the first strap 51G is made of a webbing material, the first strap 51G can be made less noticeable by making the band 90 of the same material as the rear cover portion. When providing storage compartments at the top and bottom, stitching extending to the left and right can also be provided instead of bands.

[0034] The above-described storage compartment can be provided at an appropriate position in the rear cover portion. For example, the rear cover portion of Modification 9 shown in FIG. 17 includes a third strap 53 attached to the rear cover portion 20 and another third strap 53X attached to the lower pocket 25. That is, the inner surface of the lower pocket 25 is formed of multiple cover pieces P1, P2, P3, etc., so that a pair of upper and lower seams (another lower first seam 41X and another lower second seam 42X) are formed to extend in the seat width direction. Therefore, both ends of the other third strap 53X can be attached by co-sewing between the other lower first seam 41X and the other lower second seam 42X. According to the above-described configuration, the rear cover portion 20 and the lower pocket 25 can each be provided with a storage compartment 60. Alternatively, the storage compartment 60 can be provided only on the inner or outer surface of the lower pocket 25. Alternatively, the strap can be attached so as to span between the third cover piece 23 and the inner surface of the lower pocket 25 (left and right end sides). For example, a first strap can be sewn across the front and rear sewn portions (lower first sewn portion 41, another lower first sewn portion 41X) shown in Figure 17, in which case one of the front and rear sewn portions can be considered the first sewn portion and the other the second sewn portion. Similarly, a second strap can be sewn across a pair of sewn portions (lower second sewn portion 42, another lower second sewn portion 42X). By attaching the first strap and the second strap between the third cover piece 23 and the lower pocket 25 in this manner, a storage section can be formed between the two straps.

[0035] The vehicle seat of this embodiment is not limited to the above-described embodiment and may be embodied in various other embodiments. While the present embodiment illustrates the strap configuration, this is not intended to limit the strap configuration, and the number and position of the straps can be appropriately determined. For example, an upper pocket with an open bottom may be provided at the top of the rear cover portion. In this case, the first strap and the second strap can be positioned so that they are covered by the upper pocket, or they can be provided on the upper pocket itself. Furthermore, a cover piece or fabric material that conceals the upper side of the straps like a canopy may be integrally provided on the rear cover portion. The above-described pockets, cover pieces, and fabric materials can form a covering portion that conceals the straps. Furthermore, multiple or single straps can be attached to appropriate positions on the rear cover portion, seat cover portion, gusset cover portion, top cover portion, etc. The configurations of the above-described embodiment and each modified example can be used in appropriate combination. An opening adjustment portion can be provided on the strap as needed.

[0036] The configuration of the vehicle seat can also be modified as needed, and the configuration of the seat cover, each cover piece, and seams can also be modified as needed. For example, at least a portion of the first seam and the second seam need only extend in the same direction in the surface direction of the corresponding cover portion (at least one of the seat width direction and the seat vertical direction). A strap can be attached by co-sewing to a portion of the first seam and the second seam that extend in the same direction. The type of other component is not particularly limited, and can be, for example, any component that can be stored in the storage compartment, such as accessories themselves, attachment devices for attaching accessories (such as carabiner or closed hanger), or seat accessories. The configuration of this embodiment can be applied to all vehicle seats, including those for cars, airplanes, trains, and ships. [Explanation of symbols]
