[0003] [Patent Document 1] Japanese Patent Application Publication No. 2019-111869 [Patent Document 2] Japanese Patent Application Laid-Open No. 2016-155541 [Patent Document 3] Japanese Patent Application Laid-Open No. 2016-117297 Summary of the Invention [Problem to be solved by the invention]

[0004] Incidentally, the configurations described in the above Patent Documents 1 to 3 are useful from the viewpoint of being able to suppress the occurrence of wrinkles at the edge portions of the pocket opening, but do not take into consideration the suppression of wrinkles at the edge portions of the pocket opening in a configuration in which the pocket opening is divided into multiple parts.

[0005] In consideration of the above, the present invention aims to provide a seat trim and a vehicle seat that can suppress the occurrence of wrinkles at the edge portion of the pocket opening when the pocket opening is configured to be divided into multiple parts. [Means for solving the problem]

[0006] The seat trim of the first embodiment comprises: a trim main body that forms the surface portion of the seat back that supports the back of a seated occupant; a pocket forming member that forms a pocket between the trim main body and the trim main body on the back side of the trim main body, the edge portion of the opening side of the pocket being a bag-like portion formed in a bag shape along the seat width direction, and the middle portion of the bag-like portion in the seat width direction is joined to the trim main body, so that the bag-like portion is divided in the seat width direction and the opening of the pocket is divided in the seat width direction; first reinforcing portions that are provided inside the bag-like portion and on one side and the other side of the divided portion of the bag-like portion in the seat width direction, respectively, and that reinforce the bag-like portion; and a second reinforcing portion that is provided inside the bag-like portion without interruption from one side of the seat width direction to the other side of the seat width direction with respect to the divided portion of the bag-like portion, and that reinforces the bag-like portion.

[0007] In the seat trim of the first aspect, a pocket is formed between the trim main body and the pocket forming member. The edge portion of the pocket opening side of the pocket forming member forms a bag-like portion formed along the seat width direction. The middle portion of the bag-like portion in the seat width direction is joined to the trim main body. This divides the bag-like portion in the seat width direction, and the opening of the pocket is divided in the seat width direction. First reinforcing portions are provided inside the bag-like portion of the pocket forming member and on one side and the other side of the divided portion of the bag-like portion in the seat width direction. This allows the one side of the divided portion in the seat width direction of the bag-like portion to be reinforced by one first reinforcing portion, and the other side of the divided portion in the seat width direction of the bag-like portion to be reinforced by the other first reinforcing portion. A second reinforcing portion is provided inside the bag-like portion. This second reinforcing portion is provided continuously from one side of the divided portion in the seat width direction to the other side of the divided portion in the seat width direction. This allows the bag-like portion to be reinforced by the second reinforcing portion. In this way, by providing the second reinforcing parts in addition to the first reinforcing parts, the edge of the opening of the pocket can be reinforced even when the opening of the pocket is divided into multiple parts, thereby preventing wrinkles from occurring at the edge of the opening of the pocket even when the opening of the pocket is divided into multiple parts.

[0008] The seat trim of the second aspect is the seat trim of the first aspect, wherein an intermediate portion of the bag-shaped portion in the seat width direction is joined to the trim main body by sewing.

[0009] In the seat trim of the second aspect, the middle part of the bag-shaped part in the seat width direction can be easily joined to the trim main body by sewing.

[0010] The seat trim of the third aspect is the seat trim of the first or second aspect, wherein the second reinforcing portion is provided along the edge of the opening end side of the pocket opening inside the bag-shaped portion.

[0011] In the seat trim of the third aspect, the occurrence of wrinkles at the edge of the pocket opening on the open end side can be suppressed compared to a configuration in which the second reinforcing portion is not provided at the above-mentioned position inside the bag-shaped portion.

[0012] The seat trim of a fourth aspect is the seat trim of any one of the first to third aspects, in which the first reinforcing portion and the second reinforcing portion are separate from each other.

[0013] In the seat trim of the fourth aspect, it is easier to assemble each of the first reinforcing portions and second reinforcing portions into the inside of the bag-shaped portion compared to a configuration in which each of the first reinforcing portions and second reinforcing portions is integrated.

[0014] The seat trim of the fifth aspect is the seat trim of the second aspect, wherein the second reinforcing portion is formed in a rod shape, and the second reinforcing portion is routed through the gap between the inner surface of the bag-shaped portion and the sewn portion.

[0015] In the seat trim of the fifth aspect, the rod-shaped second reinforcing part is inserted into the bag-shaped part and passes through the gap between the inner surface of the bag-shaped part and the sewn part, thereby assembling the second reinforcing part inside the bag-shaped part.

[0016] A vehicle seat of a sixth aspect comprises a seat back having a seat back main body that supports the back of a seated occupant, and a seat trim of any one of the first to fifth aspects attached to the seat back main body.

[0017] In a vehicle seat of a sixth aspect, the seat trim of any one of the first to fifth aspects is attached to a seat back main body. In this seat trim, a pocket is formed between the trim main body and a pocket forming member. An edge portion of the pocket on the opening side of the pocket in the pocket forming member is a bag-shaped portion formed along the seat width direction. A middle portion of the bag-shaped portion in the seat width direction is joined to the trim main body. This divides the bag-shaped portion in the seat width direction, and the opening of the pocket is divided in the seat width direction. First reinforcing portions are provided inside the bag-shaped portion of the pocket forming member and on one side and the other side of the divided portion of the bag-shaped portion in the seat width direction. This allows one side of the divided portion in the seat width direction of the bag-shaped portion to be reinforced by one first reinforcing portion, and the other side of the divided portion in the seat width direction of the bag-shaped portion to be reinforced by the other first reinforcing portion. A second reinforcing portion is provided inside the bag-shaped portion. The second reinforcing portion is provided continuously from one side of the divided portion of the bag-shaped portion in the seat width direction to the other side of the divided portion of the bag-shaped portion. As a result, the bag-shaped portion is reinforced by the second reinforcing portion. By providing the second reinforcing portion in addition to each first reinforcing portion in this way, even if the opening of the pocket is divided into multiple parts, the edge portion of the opening of the pocket can be reinforced. As a result, even if the opening of the pocket is divided into multiple parts, the occurrence of wrinkles at the edge portion of the opening of the pocket can be suppressed. [Effects of the Invention]

[0018] The seat trim and vehicle seat according to the present invention have the excellent effect of being able to suppress the occurrence of wrinkles at the edge of the opening of a pocket in a configuration in which the opening of the pocket is divided into a plurality of parts.

DETAILED DESCRIPTION OF THE INVENTION

[0020] 1 to 4, a vehicle seat 10 according to an embodiment of the present invention will be described. In the drawings, the arrow FR indicates the front side of the seat, the arrow UP indicates the upper side of the seat, the arrow LH indicates the left side in the seat width direction, and the arrow RH indicates the right side in the seat width direction. In the following description, unless otherwise specified, when referring to front-rear, up-down, and left-right directions, these refer to front-rear in the seat front-rear direction, up-down in the seat up-down direction, and left-right in the seat width direction.

[0021] 1, a vehicle seat 10 of this embodiment includes a seat cushion 12 that supports the buttocks of a seated occupant from below, and a seat back 14 that supports the back of the seated occupant from the rear. The seat back 14 includes a back frame 16 that forms the framework of the seat back 14, and a back pad 18 attached to the back frame 16. The back frame 16 and the back pad 18 form a seat back main body 20 that receives the load from the seated occupant. The seat back 14 also includes a back trim 22 that is attached to the seat back main body 20.

[0022] 1 and 2, the back trim 22 is formed using, for example, cloth, leather, synthetic leather, or the like. The back trim 22 includes a front covering portion 24 that covers the front surface of the seat back main body 20, a back covering portion 26 that covers the back surface of the seat back main body 20, an upper covering portion 28 that covers the upper surface of the seat back main body 20, and a pair of left and right side covering portions 30 that cover the left and right side surfaces of the seat back main body 20, respectively. The front covering portion 24, the back covering portion 26, the upper covering portion 28, and the pair of left and right side covering portions 30 form a bag-shaped trim main body 32. When the back trim 22 is attached to the seat back main body 20, the trim main body 32 forms the surface portion of the seat back 14. The back trim 22 also includes a front extension portion 34 extending downward from the front covering portion 24, a rear extension portion 36 extending downward from the back covering portion 26, and a locking member 38 attached to the end of the rear extension portion 36 opposite the back covering portion 26. Note that the locking member 38 is not shown in FIG. 1. The front extension portion 34 is arranged along the underside of the seat back main body 20. The rear extension portion 36 is arranged along the underside from the rear surface of the seat cushion 12. Furthermore, the locking member 38 is arranged to be locked to a locking portion provided on the lower part of the seat cushion 12.

[0023] The back surface covering portion 26 includes a central covering portion 26A that covers most of the middle portion in the left-right direction of the back surface of the seat back main body 20, and a pair of left and right side covering portions 26B that respectively cover both side portions in the left-right direction of the back surface of the seat back main body 20. The central covering portion 26A and the pair of left and right side covering portions 26B are joined by sewing or the like.

[0024] The back trim 22 also includes a pocket forming member 42 that forms a pocket 40 on the back side of the back trim 22. The pocket forming member 42 is formed in a rectangular shape when viewed from the rear side. The lower end of the pocket forming member 42 is joined to the lower end of the central covering portion 26A by sewing or the like. The left and right ends of the pocket forming member 42 are also joined to the left and right ends of the central covering portion 26A by sewing or the like. As a result, a pocket 40 having an opening 44 on the upper side is formed between the central covering portion 26A and the pocket forming member 42.

[0025] 2 and 3, the upper portion of the pocket forming member 42 is folded back toward the inside of the pocket 40 and sewn along the left-right direction. In Fig. 2, this sewn portion is indicated by a dashed line H1. As a result, the edge portion of the pocket forming member 42 on the opening 44 side of the pocket 40 becomes a bag-like portion 46 that is formed in a bag shape along the seat width direction.

[0026] 2 and 4, a vertically intermediate portion of a portion 46A of the bag-shaped portion 46 in the seat width direction is joined to the central covering portion 26A by stitching. In FIG. 4, this stitched portion is indicated by a dashed line H2. As a result, the bag-shaped portion 46 is divided in the seat width direction at the stitched portion H2. Furthermore, the opening 44 of the pocket 40 is divided in the seat width direction at the stitched portion H2.

[0027] 3 and 4, first reinforcing portions 48 are provided inside the bag-shaped portion 46 on the left and right sides of the sewn portion H2, which is a dividing portion of the bag-shaped portion 46, to reinforce the bag-shaped portion 46 and maintain the shape of the bag-shaped portion 46. These two first reinforcing portions 48 are formed, for example, using a resin material and are formed in the shape of a plate extending in the up-down and left-right directions with the front-to-rear direction as the thickness direction. Furthermore, when viewed from the rear side, the shape of the first reinforcing portion 48 is rectangular with the left-to-right direction as the longitudinal direction.

[0028] A second reinforcing portion 50 is provided inside the bag-shaped portion 46 to reinforce the bag-shaped portion 46 and maintain the shape of the bag-shaped portion 46. The second reinforcing portion 50 is formed, for example, of a wire or a wire strip formed into a rod (line) shape using a metal material. The second reinforcing portion 50 is provided inside the bag-shaped portion 46, seamlessly extending from one side in the seat width direction to the other side in the seat width direction with respect to the sewn portion H2, which is a dividing portion of the bag-shaped portion 46. The second reinforcing portion 50 is routed through a gap between the inner surface of the bag-shaped portion 46 and the sewn portion H2. The second reinforcing portion 50 is provided inside the bag-shaped portion 46 along the edge (upper edge) of the opening 44 of the pocket 40 on the open end side and along the upper ends of the two first reinforcing portions 48.

[0029] (Actions and Effects of This Embodiment) Next, the operation and effects of this embodiment will be described.

[0030] 2 to 4, in the back trim 22 of the vehicle seat 10 of the present embodiment described above, a pocket 40 having an opening 44 on the upper side is formed between the central covering portion 26A and the pocket forming member 42. This allows a vehicle occupant to store baggage or the like in the pocket 40.

[0031] Additionally, the edge portion of the pocket forming member 42 on the opening side of the pocket 40 forms a bag-like portion 46 that is formed in a bag shape along the seat width direction. Here, first reinforcing portions 48 are provided inside the bag-like portion 46 of the pocket forming member 42 and on the left and right sides of the sewn portion H2 of the bag-like portion 46. As a result, the portion of the bag-like portion 46 on the left side of the sewn portion H2 is reinforced by one of the first reinforcing portions 48. Additionally, the portion of the bag-like portion 46 on the right side of the sewn portion H2 is reinforced by the other first reinforcing portion 48.

[0032] Furthermore, a second reinforcing portion 50 is provided inside the bag-shaped portion 46. This second reinforcing portion 50 is provided continuously from one side of the bag-shaped portion 46 in the seat width direction to the other side of the sewn portion H2 of the bag-shaped portion 46 in the seat width direction. This reinforces the bag-shaped portion 46 with the second reinforcing portion 50. As a result, it is possible to suppress the occurrence of wrinkles in a portion 46A (the portion divided by the sewn portion H2) of the middle portion of the bag-shaped portion 46 in the seat width direction. By providing the second reinforcing portion 50 in addition to each first reinforcing portion 48 in this way, it is possible to reinforce the edge portion of the opening 44 of the pocket 40 even when the opening 44 of the pocket 40 is configured to be divided into multiple portions. This makes it possible to suppress the occurrence of wrinkles in the edge portion of the opening 44 of the pocket 40 even when the opening 44 of the pocket 40 is configured to be divided into multiple portions.

[0033] Furthermore, in this embodiment, the portion 46A of the middle part of the bag-shaped portion 46 in the seat width direction can be easily joined to the central covering portion 26A by sewing.

[0034] Furthermore, in this embodiment, the second reinforcing portion 50 is provided along the edge (upper edge) on the open end side of the opening 44 of the pocket 40 inside the bag-shaped portion 46. In this configuration, compared to a configuration in which the second reinforcing portion 50 is provided below the above-mentioned position, it is possible to suppress the occurrence of wrinkles at the edge on the open end side of the opening 44 of the pocket 40 and to suppress sagging at the edge on the open end side of the opening 44 of the pocket 40.

[0035] In addition, in this embodiment, the first reinforcing portions 48 and the second reinforcing portions 50 are separate bodies. This configuration makes it easier to assemble the first reinforcing portions 48 and the second reinforcing portions 50 into the bag-shaped portion 46 compared to a configuration in which the first reinforcing portions 48 and the second reinforcing portions 50 are integrated.

[0036] In addition, in this embodiment, the second reinforcing part 50, which is formed in a rod shape, can be assembled inside the bag-shaped part 46 by inserting it into the bag-shaped part 46 and passing it through the gap between the inner surface of the bag-shaped part 46 and the sewing part H2.

[0037] In the present embodiment, an example in which the second reinforcing portion 50 is formed in a rod shape has been described, but the present invention is not limited to this. For example, the second reinforcing portion 50 may also be formed in a long plate shape.

[0038] In addition, in the present embodiment, an example has been described in which the first reinforcing portions 48 and the second reinforcing portions 50 are separate bodies, but the present invention is not limited to this. Whether the first reinforcing portions 48 and the second reinforcing portions 50 are separate bodies or integrated can be determined appropriately taking into account the manufacturing process of the back trim 22, etc.

[0039] Furthermore, in the present embodiment, an example has been described in which the second reinforcing portion 50 is provided along the edge (upper edge) on the open end side of the opening 44 of the pocket 40 inside the bag-shaped portion 46, but the present invention is not limited to this. Whether or not to provide the second reinforcing portion 50 at the above-mentioned position inside the bag-shaped portion 46 can be determined appropriately taking into consideration the position in the pocket 40 where wrinkles are likely to occur, etc.

[0040] In addition, in the present embodiment, an example has been described in which the portion 46A of the middle portion of the bag-shaped portion 46 in the seat width direction is joined to the central covering portion 26A by sewing, but the present invention is not limited to this. For example, the portion 46A of the middle portion of the bag-shaped portion 46 in the seat width direction can also be joined to the central covering portion 26A using a crimping member or the like.

[0041] The above describes one embodiment of the present invention, but the present invention is not limited to the above, and it goes without saying that it can be implemented in various other modified forms within the scope of the gist of the present invention. [Explanation of symbols]
