[0019] The back cover 40 covers the rear of the seat back frame 16 (see FIG. 2). As shown in FIG. 4, the back cover 40 includes a pair of cover side portions 401 and a cover central portion 402. Each of the pair of cover side portions 401 covers each of the pair of frame bodies 221 and 222 in the seat back frame 16. The cover central portion 402 is provided between the pair of cover side portions 401. The cover central portion 402 is recessed forward relative to the pair of cover side portions 401 (see FIG. 6). As shown in FIG. 4, the cover central portion 402 has a curved portion 403 that is smoothly connected to each of the pair of cover side portions 401. The curved portion 403 has a cross-sectional arc shape that is convex toward the seat back frame 16. The upper portion of the cover central portion 402 has an opening 404. The opening 404 is recessed in a rectangular shape downward from the upper portion of the back cover 40 and penetrates the back cover 40 in the front-back direction of the seat. As shown in FIG. 3, coupling members 321 and 322 are accommodated in the opening 404. A part of the coupling members 321 and 322 protrudes rearward from the cover central portion 402 through the opening 404.

[0020] The cover member 42 is disposed above the back cover 40 and covers the rear of the headrest pillar 26. As shown in FIG. 4, the cover member 42 includes a cover main body 421, an arch portion 422 provided on the upper portion of the cover main body 421, a pair of protrusion portions 423, and an inclined portion 424.

[0021] The cover main body 421 extends in the left-right direction and is connected to the upper portion of the back cover 40. A part of the leg portions 281 and 282 of the headrest pillar 26 is accommodated inside the cover main body 421. Specifically, the cover member 42 covers the first portion 28A and the second portion 28B of the leg portions 281 and 282 (see FIG. 3).

[0022] The arch portion 422 is connected to both ends of the cover body 421 in the width direction. When viewed from the rear of the vehicle seat 10, the arch portion 422 is formed in a substantially arc shape that gradually moves upward from the cover body 421 toward the center in the width direction of the seat. A hole 425 is provided on the inside of the arch portion 422. The upper part 261 of the pillar and part of the legs 281 and 282 of the headrest pillar 26 are housed inside the arch portion 422. The arch portion 422 covers the rear of the upper part 261 of the pillar and part of the legs 281 and 282.

[0023] A pair of protrusions 423 are provided at the lower end of the cover member 42 (see also Figure 9). Each of the pair of protrusions 423 protrudes downward from the lower end of the cover body 421. The lower end of each protrusion 423 is the lowest end B1 of the cover member 42 (hereinafter also simply referred to as the lower end B1). The lower end B1 of the cover member 42 (protrusion 423) is positioned below the upper end of the bolt 361, which is the upper end A of the connecting members 321 and 322. The shape of each protrusion 423 is a roughly triangular or trapezoidal shape that tapers downward. The shape of the protrusion 423 may also be, for example, a roughly square shape.

[0024] The pair of protrusions 423 are spaced apart from each other in the seat width direction (left-right direction) of the vehicle seat 10. The inner surface of each protrusion 423 abuts against the upper part of each curved portion 403 of the back cover 40. The inner surface of each protrusion 423 is curved to match the curved shape of the curved portion 403. Of the pair of protrusions 423, one protrusion 423 abuts against the curved portion 403 in one direction in the seat width direction. Of the pair of protrusions 423, the other protrusion 423 abuts against the curved portion 403 in the other direction in the seat width direction. Note that the configuration is not limited to having a pair of protrusions 423 at the lower end of the cover member 42. For example, the lower end of the cover member 42 may have one protrusion 423, or it may not have any protrusions 423 at all.

[0025] As shown in Figure 3, the inclined portion 424 is provided at the lower end of the cover body 421 of the cover member 42. The inclined portion 424 is inclined downward and forward. That is, the inclined portion 424 is inclined downward and away from the display device 44.

[0026] The cover member 42 has a pair of insertion holes 426. Each of the pair of insertion holes 426 is provided at the lower end of the arch portion 422. Each insertion hole 426 penetrates the cover member 42 in the front-rear direction. The cover member 42 is attached to the front cover 46, which is positioned in front of the headrest pillar 26. As shown in Figure 9, the front cover 46 is positioned behind the headrest 123. When the cover member 42 is attached to the front cover 46, a pair of engaging portions 461 of the front cover 46 are inserted into and engaged with the pair of insertion holes 426 of the cover member 42. As a result, the headrest pillar 26 is covered by the front cover 46 and the cover member 42.

[0027] As shown in Figure 6, the display device 44 is provided on the back of the vehicle seat 10. The display device 44 is positioned behind the back cover 40. The back of the vehicle seat 10 faces the rear vehicle seat (hereinafter also referred to as the rear seat) in a vehicle not shown. As shown in Figure 3, in the front-to-back direction of the vehicle seat 10 (hereinafter also referred to as the seat front-to-back direction), a part of the display device 44 and the cover member 42 face each other.

[0028] As shown in Figure 2, the display device 44 comprises a monitor unit 441 capable of displaying video and images, and a coupling unit 442 (see Figure 3) that is coupled to the seat back frame 16. The monitor unit 441 comprises a display 481 and a monitor frame 482. The display 481 is, for example, a sensor-type panel display. The panel display is, for example, a liquid crystal panel or an organic EL panel. The display 481 is, for example, a rectangular shape that is elongated in the left-right direction. The display 481 is electrically connected to a video output device or image output device of a vehicle (not shown). The monitor frame 482 has a rectangular shape and surrounds the display 481. The monitor frame 482 holds the display 481.

[0029] As shown in Figure 3, the monitor portion 441 has a predetermined thickness T in the front-rear direction of the vehicle seat 10. In the front-rear direction of the vehicle seat 10, a gap C is formed between the front end of the monitor portion 441 and the rear end R of the cover member 42. The gap C is greater than or equal to the thickness T of the monitor portion 441 in the front-rear direction of the seat (C≧T).

[0030] The connecting portion 442 is provided in front of the monitor portion 441. The connecting portion 442 protrudes forward from the front end of the monitor portion 441. The connecting portion 442 rotatably holds the monitor portion 441. As shown in Figure 4, a pair of connecting portions 442 are provided spaced apart in the seat width direction. The pair of connecting portions 442 are placed on the upper surfaces of the mounting brackets 34 of the pair of connecting members 321 and 322, respectively, and connected. When the vehicle seat 10 is viewed from the rear, the connecting portion 442 is positioned between the pair of protrusions 423 on the cover member 42. That is, the connecting portion 442 is positioned inward in the seat width direction compared to the pair of protrusions 423. As shown in Figure 3, the cover member 42 is located above the connecting portion 442. Therefore, when the vehicle seat 10 is viewed from above, at least a portion of the connecting portion 442 is covered by the cover member 42.

[0031] As shown in Figure 4, the lower end B1 of the cover member 42 is positioned above the lower end B2 of the display device 44. The lower end B2 of the display device 44 is the lower end of the monitor unit 441.

[0032] As shown in Figure 5, each connecting portion 442 has a through hole 501 that penetrates vertically. With each connecting portion 442 in contact with the upper surface of the mounting bracket 34, the bolts 361 of the connecting members 321 and 322 are inserted into the through holes 501, and nuts 362 are screwed onto the bolts 361. The pair of connecting portions 442 are held between the mounting bracket 34 and the nuts 362 that constitute the connecting members 321 and 322 (see also Figure 8). The monitor portion 441 of the display device 44 is connected to the connecting members 321 and 322 and the seat back frame 16 by the connecting portions 442. The upper ends A of the connecting members 321 and 322 (the upper ends of the bolts 361) are positioned above the connecting portion 442. However, the upper ends A of the connecting members 321 and 322 may be positioned below the connecting portion 442, or the upper ends A of the connecting members 321 and 322 and the connecting portion 442 may be at the same height.

[0033] In the front-to-rear direction of the vehicle seat 10, the front end of each connecting portion 442 is positioned forward of the rear end R of the cover member 42. In other words, the rear end R of the cover member 42 is positioned behind each connecting portion 442.

[0034] The rear end of the connecting portion 442 has a pivot shaft portion 502. A support shaft 503 extending in the seat width direction is inserted into the pivot shaft portion 502. The pivot shaft portion 502 is supported by the support shaft 503. The pivot shaft portion 502 is supported by a support portion 483 of the monitor portion 441. The monitor portion 441 can rotate by a predetermined angle with the pivot shaft portion 502 and the support shaft 503 as pivot points. As shown in Figure 3, in the front-rear direction of the seat of the vehicle seat 10, the rear end R of the cover member 42 is positioned behind the connecting portion 442. The rear end R of the cover member 42 is the upper end of the inclined portion 424.

[0035] As shown in FIG. 2, in the seat width direction of the vehicle seat 10, the length L1 of the monitor portion 441 is shorter than the length L2 of the cover member 42 (L1 < L2). That is, the length L2 of the cover member 42 is longer than the length L1 of the monitor portion 441 (L2 > L1). The length L2 of the cover member 42 is the length of the cover main body 421. When viewed from the rear of the vehicle seat 10, the cover member 42 protrudes in the left - right direction with respect to both ends in the seat width direction of the monitor portion 441. Note that the length L2 of the cover member 42 is not limited to being longer than the length L1 of the monitor portion 441. For example, the length L2 of the cover member 42 may be shorter than the length L1 of the monitor portion 441, or the length L2 of the cover member 42 and the length L1 of the monitor portion 441 may be the same.

[0036] Next, a method of assembling the display device 44 to the vehicle seat 10 will be described.

[0037] As shown in FIG. 7, with the rear of the seat back frame 16 and the headrest pillar 26 open, the display device 44 is attached to the coupling members 321 and 322.

[0038] Specifically, the coupling portion 442 of the display device 44 is disposed in front of the monitor portion 441, and the bolts 361 of the coupling members 321 and 322 are inserted into the through - holes 501 of the pair of coupling portions 442. In this case, the bolts 361 are inserted into the through - holes 501 from below the through - holes 501. Thereby, as shown in FIG. 8, the lower surface of the coupling portion 442 is brought into contact with the mounting surface 341 of the mounting bracket 34. Thereby, the pair of coupling portions 442 are held by the upper surfaces of the pair of mounting brackets 34, and the monitor portion 441 is held substantially horizontally by the coupling members 321 and 322 (see FIG. 5). Next, a nut 362 is screwed onto the bolt 361 from the upper end of the bolt 361, and by tightening the nut 362, the coupling portion 442 is sandwiched between the nut 362 and the mounting bracket 34. Thereby, as shown in FIG. 9, the display device 44 is fixed to the rear of the seat back frame 16 via the pair of coupling members 321 and 322.

[0039] Next, the cover member 42 is attached so as to cover the rear of the headrest pillar 26. Specifically, as shown in Figure 9, with the arch portion 422 of the cover member 42 facing upward, the cover body 421 is inserted between the monitor portion 441 of the display device 44 and the headrest pillar 26. Then, as shown in Figure 4, the connecting portion 442 is positioned between the pair of protrusions 423, and the inner surfaces of the pair of protrusions 423 are brought into contact with the curved portion 403 of the back cover 40. This positions the cover member 42 in the seat width direction relative to the back cover 40 and the seat back frame 16. At this time, the lower end B1 of the cover body 421 and the upper ends A of the connecting members 321 and 322 are spaced apart in the vertical direction, and the lower end B1 of each protrusion 423 is positioned below the upper end (upper end A) of the bolt 361 of the connecting members 321 and 322. The lower end B1 of the cover member 42 may be positioned above the upper end A of the connecting members 321 and 322. The lower end B1 of the cover member 42 and the upper ends A of the connecting members 321 and 322 may be at the same height.

[0040] Next, with the cover member 42 covering the rear of the headrest pillar 26, the cover member 42 is engaged with the engaging portion 461 (see Figure 9) of the front cover 46. This attaches the cover member 42 to the rear of the headrest pillar 26. As a result, the assembly of the display device 44 to the back of the vehicle seat 10 is completed, as shown in Figure 6.

[0041] As shown in Figure 3, the display device 44 described above has the inclined portion 424 of the cover member 42 and the front end of the monitor portion 441 spaced apart in the front-rear direction of the seat. As shown in Figure 4, the lower end B1 of the cover member 42 is positioned above the lower end B2 of the monitor portion 441 in the display device 44. When viewed from the rear of the vehicle seat 10, the monitor portion 441 of the display device 44 covers the lower end B1 of the cover member 42, the connecting portion 442, the connecting members 321, 322 and the opening 404. As a result, the lower end B1 of the cover member 42, the connecting portion 442 and the connecting members 321, 322 are visually hidden from the occupant seated in the rear seat by the monitor portion 441.

[0042] This embodiment provides the following effects.

[0043] As shown in Figure 3, the vehicle seat 10 comprises a seat back frame 16, a display device 44 having a coupling portion 442 connected to the seat back frame 16 and a monitor portion 441 capable of displaying images, and a cover member 42 positioned to cover the coupling portion 442. The lower end B1 of the cover member 42 is positioned above the lower end B2 of the display device 44.

[0044] With this configuration, since the cover member 42 is positioned above the lower end B2 of the display device 44, it is possible to effectively suppress the enlargement of the cover member 42.

[0045] A gap C is formed between the display device 44 and the cover member 42 in the front-rear direction of the vehicle seat 10. The gap C is greater than or equal to the thickness T of the monitor section 441 in the front-rear direction of the seat.

[0046] With this configuration, since there is a predetermined gap C between the display device 44 and the cover member 42, the cover member 42 can be easily assembled after the display device 44 is attached to the seat back frame 16. Note that the gap C is not limited to being greater than or equal to the thickness T of the monitor unit 441. For example, the gap C may be less than or equal to the thickness T of the monitor unit 441.

[0047] As shown in Figure 2, in the width direction of the seat of the vehicle seat 10, the length L2 of the cover member 42 is longer than the length L1 of the monitor unit 441.

[0048] This configuration improves the visibility of the cover member 42 when attaching it, and effectively improves the ease of assembly of the cover member 42.

[0049] As shown in Figure 4, the joint 442 and the seat back frame 16 are joined to each other by connecting members 321 and 322. The upper ends A of the connecting members 321 and 322 are positioned above the joint 442. The lower end B1 of the cover member 42 is positioned below the upper ends A of the connecting members 321 and 322.

[0050] With this configuration, when the cover member 42 is attached to the seat back frame 16 to cover the joint 442, the cover member 42 can effectively cover and visually conceal the joint members 321, 322 and the joint 442. This improves the appearance of the back of the vehicle seat 10.

[0051] The lower end of the cover member 42 has a pair of protrusions 423 that are spaced apart from each other in the sheet width direction and protrude downward. The connecting portion 442 is positioned between the pair of protrusions 423.

[0052] This configuration makes it easier to position the cover member 42 when attaching it to the seat back frame 16.

[0053] As shown in Figure 3, in the front-to-rear direction of the vehicle seat 10, the rear end R of the cover member 42 is positioned behind the connecting portion 442.

[0054] With this configuration, since the rear end R of the cover member 42 is positioned behind the joint 442, the cover member 42 can effectively cover and visually conceal the joint 442. This improves the appearance of the back of the vehicle seat 10.

[0055] As shown in Figure 3, the lower end of the cover member 42 has an inclined portion 424 that slopes downward away from the monitor portion 441. However, the configuration is not limited to having an inclined portion 424 at the lower end of the cover member 42. For example, the lower end of the cover member 42 may be formed to extend downward without being inclined.

[0056] With this configuration, when the cover member 42 is assembled to the seat back frame 16 with the display device 44 attached to the seat back frame 16, interference between the lower end of the cover member 42 and the monitor portion 441 of the display device 44 can be effectively suppressed by the inclined portion 424.

[0057] In addition to the disclosures mentioned above, the following further notes are made:

[0058] (Note 1) The vehicle seat (10) comprises a seat back frame (16), a display device (44) having a coupling portion (442) connected to the seat back frame and a monitor portion (441) capable of displaying an image, and a cover member (42) arranged to cover the coupling portion, wherein the lower end (B1) of the cover member is positioned above the lower end (B2) of the display device.

[0059] With this configuration, since the cover member is positioned above the lower edge of the display device, it is possible to effectively suppress the need for the cover member to become larger.

[0060] (Note 2) In the vehicle seat described in Appendix 1, a gap (C) in the front-rear direction of the seat is formed between the display device and the cover member, and the gap may be greater than or equal to the thickness (T) of the monitor portion in the front-rear direction of the seat. With this configuration, since there is a gap of a predetermined amount or more between the display device and the cover member, the cover member can be easily assembled after the display device has been attached to the seat back frame.

[0061] (Note 3) In the vehicle seat described in Appendix 1 or 2, the length of the cover member (L2) may be longer than the length of the monitor section (L1) in the seat width direction. This configuration improves the visibility of the cover member when attaching it and effectively improves the ease of assembly of the cover member.

[0062] (Note 4) In the vehicle seat described in any one of the appendices 1 to 3, the connecting portion and the seat back frame are connected to each other by connecting members (321, 322), the upper end (A) of the connecting member is positioned above the connecting portion, and the lower end of the cover member is positioned below the upper end of the connecting member. With this configuration, when the cover member is attached to the seat back frame to cover the connecting portion, the cover member can effectively cover and visually conceal the connecting member and the connecting portion. This improves the appearance of the back of the vehicle seat.

[0063] (Note 5) In the vehicle seat described in any one of the appendices 1 to 4, the lower end of the cover member has a pair of protrusions (423) that are spaced apart from each other in the seat width direction and protrude downward, and the connecting portion may be positioned between the pair of protrusions. With this configuration, the positioning of the cover member is made easier when attaching the cover member to the seat back frame.

[0064] (Note 6) In the vehicle seat described in any one of the appendices 1 to 5, the rear end (R) of the cover member may be positioned behind the joint in the front-rear direction of the seat. With this configuration, since the rear end of the cover member is positioned behind the joint, the joint can be effectively covered and visually concealed by the cover member. This improves the appearance of the back of the vehicle seat.

[0065] (Note 7) In the vehicle seat described in any one of the appendices 1 to 6, the lower end of the cover member may have an inclined portion (424) that slopes downward away from the monitor portion. With this configuration, when assembling the cover member to the seat back frame with the display device attached to the seat back frame, interference between the lower end of the cover member and the monitor portion of the display device can be effectively suppressed by the inclined portion.

[0066] Furthermore, this disclosure may take various forms, not limited to the disclosure described above, without departing from the gist of this disclosure. [Explanation of Symbols]
