[0026] A vehicle seat 10 according to an embodiment of the present invention will be described below with reference to the drawings. Note that the arrows FR, UP, RH, IN, and OUT shown in each drawing indicate the front (direction of travel), top, right, inside, and outside of the vehicle width direction, respectively. Hereinafter, when the terms "front-rear," "left-right," and "up-and-down" are used in the description, they will refer to the front-rear direction of the vehicle, the left-right direction of the vehicle (vehicle width direction), and the up-and-down direction of the vehicle, unless otherwise specified.

[0027] <Vehicle seat configuration> First, the configuration of a vehicle seat 10 according to this embodiment will be described.

[0028] As shown in FIG. 1, a vehicle seat 10 according to this embodiment includes a seat cushion 12 on which an occupant sits, and a seat back 14 whose lower end is connected to the rear end of the seat cushion 12 and supports the upper body of the occupant, and a headrest (not shown) is attached to the upper end of the seat back 14.

[0029] (Seat cushion configuration) First, the configuration of the seat cushion according to the embodiment of the present invention will be described.

[0030] As shown in FIG. 1, the seat cushion 12 according to this embodiment includes a cushion frame (not shown) which is a skeletal member, a cushion pad 18 which is a padding material, and a cushion skin 20 which covers the cushion pad 18.

[0031] The cushion pad 18 is formed of a foam material such as urethane foam, and the cushion skin 20 is foam-molded (molded) integrally with the cushion pad 18. The cushion skin 20 is formed by sewing a plurality of skin pieces (skin pieces 22A, 22B, etc., which will be described later), and the cushion pad 18 is covered with the cushion skin 20.

[0032] 3, the cushion cover 20 includes a surface layer 20A, an intermediate layer 20B, and a back layer (not shown). The surface layer 20A is provided on the design surface 21 side of the cushion cover 20, and is made of cloth or leather. The intermediate layer 20B is made of wadding material.

[0033] The backing layer is made of a urethane or olefin film, and by providing the backing layer, when foaming the urethane used as the padding material, the urethane does not penetrate into the surface layer 20A, thereby preventing the cushion surface 20 from hardening due to the urethane impregnation.

[0034] It should be noted that the cushion cover 20 does not necessarily have to be foam-molded integrally with the cushion pad 18, and if it is not foam-molded integrally with the cushion pad 18, the backing layer is not necessary. Also, the cushion cover 20 does not necessarily require the middle layer 20B depending on the location. In other words, the configuration differs depending on the cover piece described below.

[0035] As shown in FIG. 1, the seat cushion 12 includes a main portion 22 that supports the occupant's lower back and thighs from below, and side portions 24, 26 that are provided on both sides of the main portion 22 in the seat width direction and that enable support of the occupant's lower back and thighs from the sides.

[0036] Here, for example, in the main portion 22, the cushion cover 20 is partitioned into cover pieces 22A, 22B, 22C, 22D, 22E, etc. in order from the front side along the seat front-rear direction. As shown in Fig. 3, the cushion cover 20 is sewn to each other via stitching portions 28A, 28B, 28C, 28D, 28E, etc. so that the plurality of cover pieces 22A, 22B, 22C, 22D, 22E, etc. are continuous along the seat front-rear direction so as to correspond to each portion.

[0037] The cover piece 22E is provided from the rear end 12A of the seat cushion 12 to the back surface 12B of the seat cushion 12, and a cover piece 22F is sewn to the lower end of the cover piece 22E. As shown in Fig. 2, the cover piece 22F is folded back toward the front side of the seat.

[0038] As shown in Figures 3 and 4, in this embodiment, an RFID tag (product information tag) 30 is sewn to the sewing portion 28E where the upholstery pieces 22E and 22F are sewn together, and as shown in Figure 2, the RFID tag 30 is provided at the lower end portion 12B1 of the back surface portion 12B of the seat cushion 12.

[0039] RFID tag 30 is a general term for a system that transmits and receives electromagnetic waves and radio waves between an "IC tag" and an "RFID reader (reading device)" to read and rewrite information in the IC tag without contact, and is an information medium that uses electromagnetic waves and radio waves to read and write data in the built-in memory without contact.

[0040] 5, in this embodiment, the manufacturing number of the side airbag (SAB number), the part number and manufacturing lot of the seating sensor, the inspection results according to the specifications of the seat cushion 12, the identification number of the vehicle seat for the vehicle model that the seat cushion 12 is compatible with, etc. are each recorded as electronic information, making it possible to identify the destination and the manufacturer. However, the information regarding the specifications of the seat cushion 12 is not limited to this.

[0041] (Seat back configuration) Next, the configuration of the seat back according to the embodiment of the present invention will be described.

[0042] As shown in FIG. 6, the seat back 14 according to this embodiment includes a seat back frame (not shown) which is a skeletal member, a seat back pad 32 which is a padding material, and a seat back skin 34 which covers the seat back pad 32.

[0043] The seatback pad 32 is made of a foam material such as urethane foam, similar to the cushion pad 18 (see FIG. 1), and the seatback skin 34 is foam-molded integrally with the seatback pad 32. The seatback skin 34 is formed by sewing together a plurality of skin pieces (36A, 36B, 36C, etc., which will be described later), and the seatback pad 32 is covered with the seatback skin 34.

[0044] Similarly to the cushion cover 20, the seatback cover 34 is configured to include a surface layer 34A, an intermediate layer 34B, and a back layer (not shown), as shown in Fig. 8. The surface layer 34A is provided on the design surface 35 side of the seatback cover 34, and is made of cloth or leather. Wadding material is used for the intermediate layer 34B.

[0045] The backing layer is made of a urethane or olefin film, and by providing the backing layer, the urethane does not penetrate into the surface layer when foaming the urethane used as the padding material, which prevents the seat back skin 34 from hardening due to urethane impregnation.

[0046] The seatback skin 34 does not necessarily have to be foam-molded integrally with the seatback pad 32, and if it is not foam-molded integrally with the seatback pad 32, the backing layer is not necessary. Also, the seatback skin 34 does not necessarily require the intermediate layer 34B depending on the location. In other words, the configuration differs depending on the skin piece described below.

[0047] 6, the seat back 14 is configured to include a main portion 36 that supports the upper body of the occupant from the rear side, and side portions 38, 40 that are provided on both sides in the seat width direction around the main portion 36 and enable support of the upper body of the occupant from the sides. Note that a side airbag (SAB), not shown, is housed inside the side portion 40, which is located on the outer side in the vehicle width direction.

[0048] Here, for example, in the main portion 36, the seat back cover 34 is divided into cover pieces 36A, 36B, 36C, etc. in order from the upper side along the vertical direction of the seat. As shown in Fig. 8, the seat back cover 34 is sewn together via stitching portions 42A, 42B, etc. so that the plurality of cover pieces 36A, 36B, 36C, etc. are continuous along the vertical direction of the seat so as to correspond to each portion.

[0049] Meanwhile, a back portion 44 connected to the main portion 36 of the seat back cover 34 is provided on the back surface 14A side of the seat back 14. In the back portion 44, the seat back cover 34 is divided into cover pieces 44A, 44B, 44C, etc. in order from the upper side along the vertical direction of the seat. The cover pieces 44A, 44B, 44C, etc. are sewn to each other via stitching portions 46A, 46B, etc. so as to be continuous along the vertical direction of the seat.

[0050] In this embodiment, a blinding member 48 as part of the seat back skin 34 hangs down from the lower side of the back surface 14A of the seat back 14. A reinforcing plate 50 is provided on the inner surface of the blinding member 48 so as to maintain the shape of the blinding member 48. The blinding member 48 conceals the lower part of the back surface 14A side of the seat back 14, and prevents the lower part of the back surface side of the vehicle seat 10 from being seen by an occupant seated on the rear side of the vehicle seat 10.

[0051] 10 , in this embodiment, for example, an RFID tag (product information tag) 52 similar to the RFID tag 30 is adhered to the inside of the plate 50. That is, in this embodiment, by providing the RFID tag 52 on the inside of the plate 50 provided on the inner side of the blind member 48 as part of the seat back skin 34, the RFID tag 52 is not exposed to the outside of the seat back skin 34.

[0052] In this embodiment, for example, similar to the RFID tag 30, the manufacturing number of the side airbag (SAB number), the part number and manufacturing lot of the seating sensor, the inspection results according to the specifications of the seat back 14, the identification number of the vehicle seat for the vehicle model that the seat back 14 is compatible with, etc. are each recorded as electronic information, making it possible to identify the destination and manufacturer.

[0053] The RFID tag 52 does not necessarily have to have the same information as the RFID tag 30, and may have part of the same information, or may have different information recorded thereon.

[0054] <Functions and Effects of Vehicle Seats> Next, the operation and effects of the vehicle seat according to the embodiment of the present invention will be described.

[0055] In this embodiment, as shown in Figures 1 and 2, an RFID tag 30 recording product information of the seat cushion 12 is provided on the inside of the cushion cover 20. Also, as shown in Figures 7 and 8, an RFID tag 52 recording product information of the seat back 14 is provided on the inside (plate 50) of the blind member 48 of the seat back 14.

[0056] The RFID tags 30, 52 can be read from the outside, so even when the RFID tags 30, 52 are housed inside the seat cushion 12 and the seat back 14, the product information written on the RFID tags 30, 52 can be read.

[0057] In other words, in this embodiment, by using RFID tags 30, 52 that can read product information about the seat cushion 12 and the seat back 14 from the outside, the RFID tags 30, 52 can be installed inside the cushion cover 20 and the concealing member 48, respectively, without being exposed to the outside.

[0058] For example, although not shown, the RFID tag 30 can be attached to the inside of the cushion cover 20 or to the cushion pad 18 side covered with the cushion cover 20, thereby enabling the RFID tag 30 to be provided with a simple configuration on the back side of the cushion cover 20 or inside the cushion pad 18. The RFID tag 52 is similar to the RFID tag 30.

[0059] As described above, in this embodiment, the product information of the seat cushion 12 can be read by the RFID tag 30, and the product information of the seat back 14 can be read by the RFID tag 52. Therefore, in this embodiment, the product information of the seat cushion 12 and the seat back 14 does not depend on the shapes of the seat cushion 12 and the seat back 14 themselves, and it is possible to prevent identification errors by workers.

[0060] Therefore, in this embodiment, the number of steps required to identify the product information of the seat cushion 12 and the seat back 14 can be reduced, and as a result, an increase in the cost of the vehicle seat 10 can be suppressed.

[0061] More specifically, in this embodiment, RFID tags 30 and 52 are used to identify the product information of the seat cushion 12 and the seat back 14, respectively, and the product information written on the RFID tags 30 and 52 can be read within the range of the radio waves of an RFID reader (not shown) even if the RFID tags 30 and 52 are not exposed to the outside.

[0062] Therefore, for example, in this embodiment, the RFID tag 30 can be provided on the back side of the cushion cover 20 or inside the cushion pad 18. Therefore, although not shown, the design can be improved compared to when the RFID tag 30 is exposed to the outside of the seat cushion 12. Furthermore, in this embodiment, by providing the RFID tag 30 on the back side of the cushion cover 20 or inside the cushion pad 18, it is not necessary to remove the cushion cover 20 to read the product information of the seat cushion 12, and the product information of the seat cushion 12 can be identified with a simple operation. Therefore, the work efficiency associated with identifying the product information of the seat cushion 12 is improved.

[0063] Furthermore, by using RFID tags 30, 52 to read the product information of the seat cushion 12 and the seat back 14, respectively, the RFID tag 30 may be attached to the inner surface of the cushion skin 20, or may be provided inside the cushion pad 18, although this is not shown in the drawings. In other words, in this embodiment, the specifications of the seat cushion 12 and the seat back 14 can be identified with a simple configuration and with a simple operation.

[0064] Furthermore, in this embodiment, by using the RFID tags 30 and 52 as product information tags for reading product information, it is possible to add to and update the recorded product information, which makes the system highly versatile.

[0065] Furthermore, in this embodiment, the RFID tag 30 is foam-molded integrally with the cushion pad 18 together with the cushion skin 20. This eliminates the need for a process of covering the cushion pad 18 with the cushion skin 20, thereby reducing the number of work steps.

[0066] In addition, in this embodiment, as shown in Figure 2, the RFID tag 30 is provided at the lower end 12B1 of the back portion 12B of the seat cushion 12, and as shown in Figure 7, the RFID tag 52 is provided on the front side of the privacy member 48 of the seat back 14.

[0067] In other words, the RFID tags 30, 52 are provided in locations where they will not be directly hit by people or objects. This prevents people or objects from colliding with the RFID tags 30, 52 in this embodiment, thereby reducing the risk of damage to the RFID tags 30, 52.

[0068] 3 and 4, in this embodiment, the RFID tag 30 is sewn together with the sewn portion 28E where the adjacent skin pieces 22E and 22F are sewn together. In other words, the RFID tag 30 can be sewn by sewing the minimum amount of the sewn portion 28E. Therefore, compared to when a separate sewing operation is performed to sew the RFID tag 30, this embodiment makes it possible to suppress an increase in the number of work steps.

[0069] In this embodiment, the RFID tag 30 is sewn to the sewn portion 28E, but this is not limited to the sewn portion 28E. Furthermore, the RFID tag 30 does not necessarily have to be sewn to the sewn portion. Furthermore, in this embodiment, an example has been described in which the cushion cover 20 to which the RFID tag 30 is sewn is foam-molded integrally with the cushion pad 18, but the cushion cover 20 does not necessarily have to be foam-molded integrally with the cushion pad 18.

[0070] In addition, in this embodiment, the RFID tag 30 is sewn to the cushion cover 20, but since it is sufficient that the RFID tag 30 is provided integrally with the cushion pad 18, it is not necessarily required that the RFID tag 30 be sewn to the cushion cover 20. Therefore, the RFID tag 30 may be adhered to the cushion pad 18.

[0071] Furthermore, in this embodiment, RFID tags 30 and 52 are used to identify the product information of the seat cushion 12 and the seat back 14, respectively. However, as long as the product information can be identified from the outside of the seat cushion 12 and the seat back 14, the product information tag does not necessarily have to be the RFID tag 30 or 52.

[0072] In addition, the present invention can be implemented with various modifications within the scope of the gist thereof. Furthermore, it goes without saying that the scope of the rights of the present invention is not limited to the above-described embodiment. [Explanation of symbols]
