That is, in this prior art, there is room for further improvement from the viewpoint of appearance.

[0005] In consideration of the above facts, an object of the present invention is to obtain a headrest and a vehicle seat that can identify the specifications of the headrest body with a simple operation without damaging the aesthetics.

Means for Solving the Problems

[0006] The headrest according to the invention described in claim 1 is provided above the seat back of a vehicle seat, and includes a headrest pad formed of a foaming material and supporting the head of an occupant seated on the seat cushion, a headrest stay serving as a skeletal member of the headrest pad and integrally formed with the headrest pad, with a pair of legs exposed from the headrest pad and arranged along the seat width direction being attached to the upper end of the seat back, a headrest skin formed by sewing a plurality of skin pieces and covering the headrest pad, and a product information tag provided integrally with the headrest pad and recording product information of the headrest body and being readable from the outside. Moreover, the product information tag is an RFID tag, and the RFID tag is integrally molded with the headrest pad together with the headrest skin, and is sewn so as to be arranged along the flow direction of the material forming the headrest pad with respect to the skin piece forming at least a part of the injection port for injecting the material forming the headrest pad. 。

[0007] The headrest according to the invention described in claim 1 includes a headrest pad, a headrest stay, a headrest skin, and a product information tag.

[0008] The headrest pad is provided above the seat back of a vehicle seat and is formed of a foaming material to support the head of an occupant seated on the seat cushion. The headrest stay serves as a skeletal member of the headrest pad and is integrally formed with the headrest pad. Also, a pair of legs arranged along the seat width direction are exposed from the headrest pad, and the pair of legs are attached to the upper end of the seat back. The headrest skin is formed by sewing a plurality of skin pieces, and the headrest pad is covered by the headrest skin.

[0009] Here, in the present invention, a product information tag recording product information of the headrest body and being readable from the outside is provided integrally (such as integrally formed or adhered) with the headrest pad. The product information of the headrest body refers to, for example, information corresponding to the specifications of the headrest body (applicable vehicle models, etc.), and the numbers of used parts (part numbers), manufacturing lots, etc. are recorded.

[0010] Since the product information tag can be read from the outside, the product information written on the product information tag can be read even when the product information tag is housed inside the headrest body.

[0011] Thus, in the present invention, by using a product information tag that can be read from the outside to read the product information of the headrest body, the product information tag can be provided on the back side of the headrest skin or inside the headrest pad. Thereby, in the present invention, it is not necessary to remove the headrest skin to read the product information of the headrest body.

[0012] As described above, in the present invention, the product information of the headrest body can be identified by a simple operation. Therefore, the work efficiency associated with the identification of the product information of the headrest body is improved. In addition, since the product information of the headrest body does not depend on the shape of the headrest body itself, it is possible to suppress identification errors by the operator.

[0013] Therefore, in the present invention, the man-hours associated with the identification of the product information of the headrest body can be reduced, and as a result, it is possible to suppress an increase in the cost of the headrest body.

[0014] Also, in the present invention, the The said product information tag is an RFID tag.

[0015] RFID is an abbreviation of "Radio Frequency Identification", the RFID tag is also called an RF tag, and the electronic information recorded on the RFID tag can be read and written by an RFID reader, which is a device capable of reading and writing, within the range where the radio wave of the RFID reader reaches.

[0016] Therefore, by attaching an RFID tag, within the range where the radio waves of the RFID reader can reach, even when the RFID tag is housed inside the headrest body, the product information written on the RFID tag can be read. Also, it is possible to write product information on the RFID tag, and it is also possible to add or update the product information.

[0017] Furthermore, in the present invention, the The RFID tag is integrally foam-molded with the headrest pad together with the headrest skin.

[0018] As described above, within the range where the radio waves of the RFID reader can reach, even when the RFID tag is housed inside the headrest body, the product information written on the RFID tag can be read.

[0019] In the present invention, By integrally foam-molding the RFID tag with the headrest pad together with the headrest skin, the process of covering the headrest pad with the headrest skin can be reduced, and the man-hours of work can be reduced. Also, in the present invention, the RFID tag is sewn so as to be arranged along the flow direction of the material forming the headrest pad with respect to the skin piece forming at least a part of the injection port for injecting the material forming the headrest pad. Thereby, in the present invention, the orientation of the RFID tag can be set more reliably along the flow direction of the material forming the headrest pad during the molding of the headrest pad, and the twisting or folding of the RFID tag can be suppressed more effectively.

[0020] Claim 2 The headrest according to the invention described in claim to 1 In the headrest according to the invention described in claim

[0021] Claim 2 In the headrest according to the invention described in claim Since the RFID tag is provided at the bottom mat part of the headrest skin, which is a part where people and objects do not directly hit, it is possible to prevent people and objects from colliding with the RFID tag and reduce the risk of damage to the RFID tag.

Modes for Carrying Out the Invention

[0034] ​​Hereinafter, the headrest according to an embodiment of the present invention will be described with reference to the drawings. Note that the arrows FR, UP, and RH appropriately shown in each drawing indicate the front, upper, and right directions of the headrest, respectively. Hereinafter, when simply describing the directions of front, rear, left, right, up, and down, unless otherwise specified, they indicate the directions with respect to the headrest. Also, in each drawing, some reference numerals may be omitted for ease of viewing the drawing.

[0035] (Configuration of Headrest) First, the configuration of the headrest according to an embodiment of the present invention will be described.

[0036] As shown in FIG. 1, the headrest 10 according to the present embodiment includes a headrest stay 12 which is a skeletal member, a headrest pad 14 which is a padding material, and a headrest skin 16.

[0037] The headrest stay 12 is, for example, a metal pipe material bent in a substantially reverse U shape, and includes a pair of left and right legs 12L and 12R extending in the up and down direction of the headrest, and a connecting portion 12U (see FIG. 2) connecting the upper end portions of the pair of left and right legs 12L and 12R in the left and right direction of the headrest.

[0038] The headrest pad 14 is formed of a foaming material such as urethane foam, for example. The upper side of the headrest stay 12 is embedded in the headrest pad 14. The lower sides of the left and right legs 12L and 12R extend downward from the headrest pad 14 to the headrest 10 and are connected to the upper end portion 18A of the seat back 18 of the vehicle seat 11. The headrest pad 14 is supported by the headrest stay 12.

[0039] As shown in FIG. 2, the headrest skin 16 is integrally foam-molded (formed) with the headrest pad 14 and includes, for example, a surface layer 20, an intermediate layer 22, and a back layer (not shown).

[0040] The surface layer 20 is provided on the design surface 16A side of the headrest skin 16, and a cloth-based or leather-based material is used. A padding material is used for the intermediate layer 22. For the back layer, films such as urethane-based and olefin-based films are used. By providing the back layer, when foaming urethane as the padding material, it is possible to prevent the urethane from impregnating the surface layer side. Thereby, hardening of the headrest skin 16 due to the impregnation of urethane can be prevented.

[0041] Also, the headrest skin 16 is formed by sewing a plurality of skin pieces (front skin piece 16B, back skin piece 16C, etc., which will be described later), and the headrest pad 14 is covered by the headrest skin 16.

[0042] Specifically describing the headrest skin 16, for example, a front skin piece 16B is provided on the front 14A side of the headrest pad 14, and a back skin piece 16C is provided on the back 14B side of the headrest pad 14. The upper end portion 16B1 of the front skin piece 16B and the upper end portion 16C1 of the back skin piece 16C are sewn by a sewing portion 24, and the front skin piece 16B and the back skin piece 16C are connected via the sewing portion 24.

[0043] The lower end portion 16B2 of the front skin piece 16B is connected to the front end portion 16D1 of the front bottom skin piece (bottom mat portion) 16D via a sewing portion 26. On the other hand, the lower end portion 16C2 of the back skin piece 16C is connected to the rear end portion 16E1 of the rear bottom skin piece (bottom mat portion) 16E via a sewing portion 28.

[0044] And the rear end portion 16D2 of the front bottom skin piece 16D and the front end portion 16E2 of the rear bottom skin piece 16E are connected via a sewing portion (not shown). However, between the rear end portion 16D2 of the front bottom skin piece 16D and the front end portion 16E2 of the rear bottom skin piece 16E of the headrest skin 16, an injection port 32 for injecting the material forming the headrest pad 14 is formed between the leg portions 12L and 12R (see FIG. 1) of the headrest stay 12. For this reason, the sewing portion is provided outside the injection port 32 in the sheet width direction.

[0045] In addition, in FIGS. 2 and 3, a gap indicating the injection port 32 is provided between the front bottom skin piece 16D and the rear bottom skin piece 16E. This is for clearly showing the terminal of the sewing part 30, but actually this gap is in a state where it is hardly formed.

[0046] On the other hand, as shown in FIG. 3, in this embodiment, an RFID tag (product information tag) 34 is sewn to the rear bottom skin piece 16E that constitutes a part of the injection port 32 via the sewing part 30. Note that the RFID tag 34 may be sewn to the front bottom skin piece 16D side that constitutes a part of the injection port 32, and further may be sewn to a skin piece other than the rear bottom skin piece 16E and the front bottom skin piece 16D regardless of the injection port 32.

[0047] Here, the RFID tag 34 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)", and reads and rewrites information in the IC tag non - contact. It is an information medium that reads and writes data in the built - in memory non - contact using electromagnetic waves and radio waves.

[0048] In this embodiment, for example, as shown in FIG. 4, the manufacturing number (SAB number) of the side airbag, the part number and manufacturing lot of the seating sensor, the inspection result according to the specification of the headrest 10, the identification number of the vehicle seat corresponding to the vehicle type to which the headrest 10 corresponds, etc. are each recorded as electronic information, and the destination and the identification of the manufacturing company are made possible. Note that the information regarding the specification of the headrest 10 is not limited to this.

[0049] (Function and Effect of the Headrest) Next, the function and effect of the headrest according to the embodiment of the present invention will be described.

[0050] As shown in FIGS. 1 and 2, in this embodiment, an RFID tag 34 in which product information of the headrest 10 is recorded is integrally foam-molded with the headrest pad 14 together with the headrest skin 16.

[0051] Thus, by using the RFID tag 34 to identify the product information of the headrest 10, even when the RFID tag 34 is housed inside the headrest within the reach of the radio wave of an RFID reader (not shown), the product information written in the RFID tag 34 can be read.

[0052] Therefore, in this embodiment, by using the RFID tag 34 to read the product information of the headrest 10, the RFID tag 34 can be provided on the back side of the headrest skin 16 or inside the headrest pad 14.

[0053] As a result, in this embodiment, it is not necessary to remove the headrest skin 16 to read the product information of the headrest 10. Thus, in this embodiment, the product information of the headrest 10 can be identified by a simple operation. For this reason, the working efficiency associated with the identification of the product information of the headrest 10 is improved.

[0054] Further, in this embodiment, since the product information of the headrest 10 does not depend on the shape of the headrest 10 itself or the like, it is possible to suppress misidentification by the operator.

[0055] Therefore, in this embodiment, the man-hours associated with the identification of the product information of the headrest 10 can be reduced, and as a result, it is possible to suppress an increase in the cost of the headrest 10.

[0056] Also, by using the RFID tag 34 to read the product information of the headrest 10, although not shown, the RFID tag 34 can be provided on the back skin piece 16C side of the headrest skin 16 or inside the headrest pad 14.

[0057] Therefore, in the present embodiment, it is possible to identify the product information of the headrest 10 with a simple operation without impairing the aesthetics.

[0058] In addition, in the present embodiment, by using the RFID tag 34 as the product information tag for reading the product information, it is also possible to add and update the recorded product information, so the versatility is high.

[0059] Furthermore, in the present embodiment, the RFID tag 34 is integrally foam-molded with the headrest pad 14 together with the headrest skin 16. Therefore, the process of covering the headrest pad 14 with the headrest skin 16 can be reduced, and the man-hour can be reduced.

[0060] In addition, in the present embodiment, the RFID tag 34 is provided on the bottom mat portion 16F formed by the front bottom skin piece 16D and the rear bottom skin piece 16E of the headrest skin 16. This bottom mat portion 16F is a part where people and objects do not directly hit.

[0061] Therefore, by providing the RFID tag 34 on the bottom mat portion 16F, it is possible to prevent people and objects from colliding with the RFID tag 34 and reduce the risk of damage to the RFID tag 34.

[0062] Here, an injection port 32 for injecting the material for forming the headrest pad 14 is provided in the bottom mat portion 16F of the headrest skin 16. That is, when the headrest pad 14 is molded, the material for molding the headrest pad 14 is injected through the injection port 32.

[0063] Therefore, the material for molding the headrest pad 14 flows along the vertical direction of the seat from the bottom surface 14C side of the headrest pad 14 toward the upper portion 14D side of the headrest pad 14.

[0064] In this embodiment, the RFID tag 34 is integrally formed with the headrest pad 14. Although not shown, in the mold for forming the headrest pad 14, the gate portion for injecting the foaming material is generally provided on the bottom surface 14C side of the headrest pad 14. Therefore, the material injected into the mold through the gate portion will flow along the vertical direction of the seat from the bottom surface 14C side of the headrest pad 14 toward the upper portion 14D side of the headrest pad 14.

[0065] In this embodiment, since the RFID tag 34 is provided along the vertical direction of the seat, the RFID tag 34 is provided along the flow direction of the material flowing in the mold for forming the headrest pad 14.

[0066] Therefore, when the headrest pad 14 is being formed, the RFID tag 34 can be prevented from being twisted or broken, and damage to the RFID tag 34 can be suppressed.

[0067] Also, in this embodiment, the RFID tag 34 is sewn to the rear bottom surface skin piece 16E that constitutes a part of the injection port 32. As described above, when the headrest pad 14 is being formed, the material for forming the headrest pad 14 is injected through the injection port 32.

[0068] Therefore, by sewing the RFID tag 34 to the rear bottom surface skin piece 16E that constitutes a part of the injection port 32, the orientation of the RFID tag can be set along the flow direction of the material for forming the headrest pad substantially simultaneously with the injection of the material when the headrest pad is being formed, and twisting or folding of the RFID tag can be more effectively suppressed.

[0069] In this embodiment, an example in which the headrest skin 16 to which the RFID tag 34 is sewn is integrally foam-molded with the headrest pad 14 has been described. However, the headrest skin 16 does not necessarily need to be integrally foam-molded with the headrest pad 14.

[0070] In addition, in this embodiment, the RFID tag 34 is sewn to the headrest skin 16. However, since it is sufficient that the RFID tag 34 is provided integrally with the headrest pad 14, it is not necessarily sewn to the headrest skin 16. Therefore, the RFID tag 34 may be adhered to the headrest pad 14. Also, since the product information tag only needs to be readable from the outside of the headrest 10, it does not necessarily have to be the RFID tag 34.

[0071] In addition, the present invention can be implemented with various modifications without departing from the gist thereof. Of course, the scope of the rights of the present invention is not limited to the above-described embodiment.
