[Technical Field]

[0001] The present invention relates to a vehicle seat, and more particularly to a vehicle seat including a headrest and a speaker provided inside the headrest. [Background technology]

[0002] BACKGROUND ART Conventionally, vehicle seats having a speaker (sound device) mounted inside the headrest are known. For example, Patent Document 1 discloses a headrest that includes left and right speakers and a speaker assembly for assembling the left and right speakers. The speaker assembly includes left and right speaker holders (enclosures) that hold the left and right speakers in a state where they are exposed toward the front of the seat, and a connecting portion (connecting plate) that connects the left and right speaker holders. The left and right speaker holders are attached to the connecting portion with assembly bolts. The speaker assembly is also attached to the headrest (headrest pillar) via a mounting plate. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Special Publication No. 2017-525456 Summary of the Invention [Problem to be solved by the invention]

[0004] However, in a headrest equipped with a speaker such as that disclosed in Patent Document 1, the structure of the headrest is relatively complicated, and therefore there has been a demand for easier assembly of the speaker and speaker assembly to the headrest (headrest pillar).There has also been a demand for a simpler configuration of the speaker assembly.

[0005] The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to provide a vehicle seat in which a speaker can be attached to a headrest more easily than in the past. Another object of the present invention is to provide a vehicle seat in which the structure of a speaker assembly for assembling a speaker can be made simpler than in the past. [Means for solving the problem]

[0006] The above problem is solved by the vehicle seat of the present invention, which provides a vehicle seat including a headrest and left and right speakers provided inside the headrest, and a speaker assembly provided inside the headrest for assembling the speakers, the speaker assembly having left and right speaker holding portions provided on the left and right sides of the headrest and holding the left and right speakers, respectively, and a connecting portion connecting the left and right speaker holding portions and formed integrally with the left and right speaker holding portions. The above configuration makes it possible to realize a vehicle seat in which the speaker can be attached to the headrest more easily than before. Specifically, the speaker assembly includes left and right speaker holders and a connecting portion that connects the left and right speaker holders and is formed integrally with the speaker holders. Therefore, unlike conventional systems, assembly bolts and plates are not required, and the speaker assembly structure can be simplified compared to conventional systems. The number of parts in the speaker assembly can also be reduced. In other words, the speaker can be assembled to the headrest more easily than conventional systems.

[0007] In this case, the speaker holding portion has a storage recess for storing the speaker, and the speaker is preferably stored in the storage recess from the front-to-rear direction of the seat and held in an exposed state on the front side of the seat. With the above-described configuration, the speaker can be housed in the speaker holding portion (housing recess) in a state where the speaker is exposed to the front side of the seat with a simple configuration. Furthermore, as described above, by accommodating the speaker in the accommodating recess, the speaker can be suitably protected from external impacts, for example.

[0008] In this case, the speaker is preferably housed so as to penetrate the housing bottom surface of the housing recess and is held in a state where it is exposed to the front side and the rear side of the seat from the speaker holding portion. With the above-described configuration, the speaker can be appropriately held and housed in the speaker holding portion (housing recess), and the speaker assembly state can be visually confirmed from the front and rear of the seat.

[0009] In this case, the vehicle seat may further include a harness connected to the speaker, and the speaker holding portion may have the storage recess provided in a forward position of the speaker holding portion and for storing the speaker, the rear storage recess provided in a rear position of the speaker holding portion and for storing the harness, and a lid portion that covers the rear storage recess from the rear of the seat, and the speaker may pass through the storage bottom surface of the storage recess and the storage bottom surface of the rear storage recess in the fore-and-aft direction of the seat, and be held in a state where it is exposed from the speaker holding portion to the front and rear sides of the seat. With the above-described configuration, the speaker can be accommodated in the speaker holding portion from the front of the seat, and the harness can be accommodated from the rear of the seat. Furthermore, with the above-described configuration, the rear accommodating recess for accommodating the harness is covered with the lid, which prevents foreign matter from unintentionally entering the rear accommodating recess, thereby providing optimal protection for the speaker and the harness.

[0010] In this case, the headrest further includes a pillar that supports the main body of the headrest, and a rear cover that is attached to the pillar and positioned to cover the pillar and the speaker assembly from behind the seat, and the rear cover has a pillar hook portion for hooking onto the pillar and left and right mounting portions for attaching the speaker assembly, and the pillar hook portion is preferably positioned between the left and right mounting portions in the seat width direction. In addition, the pillar hook portion is preferably positioned so as to overlap the left and right mounting portions in the vertical direction, and the speaker is preferably positioned between the upper end of the mounting portion and the lower end of the connecting portion in the vertical direction. With the above-described configuration, the rear cover, the speaker assembly, and the speaker can be firmly attached to the pillar (headrest pillar) that serves as the core material of the headrest.

[0011] In this case, the headrest is provided with a pillar that supports the main body of the headrest, and the speaker assembly is preferably arranged so that the left and right speaker holding portions cover the pillar from both sides in the seat width direction, and the connecting portion covers the pillar from the rear side of the seat. With the above-described configuration, the speaker assembly can be attached more firmly to the pillar of the headrest. As described above, the speaker assembly is disposed so as to surround the pillar on both sides in the seat width direction and from the rear side of the seat, which prevents the speaker assembly and the speaker from shaking (moving) in the left-right and front-rear directions relative to the headrest (headrest pillar) while the vehicle is moving, for example.

[0012] In this case, the headrest further includes a pillar that supports the main body of the headrest, and a front cover that is attached to the pillar and positioned to cover the pillar and the speaker assembly from the front of the seat, and the front end of the speaker holding portion protrudes toward the front cover and is positioned in contact with or able to contact the rear surface of the front cover. Furthermore, the speaker holding portion has a protruding wall portion that protrudes from the outer edge portion of the main body of the speaker holding portion toward the front of the seat, and the protruding wall portion has an upper wall portion that protrudes from the upper end of the main body of the speaker holding portion and a bottom wall portion that protrudes from the lower end of the main body of the speaker holding portion, and the front ends of each are preferably abutting or positioned so as to be abuttable against the rear surface of the front cover. The above-described configuration increases the assembly strength between the front cover and the speaker assembly, and also allows the speaker assembly to suitably support the front cover when an external load is applied from the front side of the seat.

[0013] In this case, the vehicle seat may further include left and right microphones provided inside the headrest, and the speaker holding portion may hold the speaker in an exposed state on the front side of the seat, and may also hold the microphone in an exposed state on the front side of the seat at a position different from the speaker. The above configuration makes it easier to assemble the speaker and microphone into the headrest (speaker assembly) than in the past. Also, the speaker and microphone can be mounted inside the headrest without increasing the number of parts in the speaker assembly. [Effects of the Invention]

[0014] According to the present invention, it is possible to realize a vehicle seat that allows a speaker to be assembled to a headrest more easily than in the past, and also to simplify the structure of the speaker assembly compared to the past. Furthermore, according to the present invention, the speaker can be housed in the speaker holding portion (housing recess) with a simple structure, with the speaker exposed to the front side of the seat. The speaker can be protected from external impacts, for example. Furthermore, the speaker installation status can be visually confirmed from the front and rear of the seat. According to the present invention, the speaker can be accommodated in the speaker holder from the front of the seat, and the harness can be accommodated from the rear of the seat. Furthermore, the above-described configuration makes it possible to provide suitable protection for the speaker and the harness. Furthermore, according to the present invention, the rear cover, the speaker assembly, and the speaker can be firmly attached to the pillar that serves as the core material of the headrest. Furthermore, according to the present invention, it is possible to prevent the speaker assembly and the speaker from shaking left and right and front and rear relative to the headrest (pillar) while the vehicle is traveling, for example. Furthermore, according to the present invention, the assembly strength between the front cover and the speaker assembly can be increased. Furthermore, according to the present invention, the speaker and microphone can be assembled to the headrest (speaker assembly) more easily than before. [Brief explanation of the drawings]

[0016] Hereinafter, an embodiment of the present invention will be described with reference to FIGS. 1 to 14C. This embodiment relates to a vehicle seat having a headrest and left and right speakers provided inside the headrest, wherein the headrest has a speaker assembly for assembling the speakers, and the speaker assembly has left and right speaker holding portions that hold the left and right speakers exposed on the front side of the seat, and a connecting portion that connects the left and right speaker holding portions and is formed integrally with the left and right speaker holding portions. The side of the vehicle seat where the occupant sits relative to the seat back (headrest) is the front side of the seat.

[0017] As shown in FIG. 1, the vehicle seat S of this embodiment is a vehicle seat, and includes a seat body having a seat cushion 1, a seat back 2, and a headrest 3, and as shown in FIG. 3, a blower device 4 attached to the inside of the seat back 2 and blowing air toward the seated occupant, a speaker 5 attached to the inside of each headrest 3 and outputting sound toward the seated occupant, and a microphone 6 that receives sound from the seated occupant or from the outside and converts it into an electrical signal. The vehicle seat S also includes a control device 7 that is attached to the seat body, connected to the blower device 4, the speaker 5, and the microphone 6, and controls the blower device 4, the speaker 5, and the microphone 6. In addition, the vehicle seat S may further include a rail device that supports the seat body so that it can move back and forth relative to the vehicle floor, a height link device that connects the seat body to the vehicle floor so that it can be raised and lowered, and a reclining device that connects the seat back 2 to the seat cushion 1 so that it can be rotated.

[0018] As shown in FIG. 1, the seat cushion 1 is a seating portion that supports the seated person from below, and is mainly composed of a cushion frame 10 that serves as the skeleton, a cushion material 1a that is placed on the cushion frame 10, and a cover material 1b that covers the cushion frame 10 and the cushion material 1a. As shown in Figures 1 and 3, the seat back 2 is a backrest portion that supports the seated occupant from behind, and is mainly composed of a back frame 20 that forms the skeleton, a cushion material 2a, and a cover material 2b.

[0019] As shown in Figures 1 to 3, the headrest 3 is a head support that supports the occupant's head from behind, and is mainly composed of a headrest frame 30 that serves as a skeleton, cushion materials 3a and 3b that are placed on the headrest frame 30, and skin materials 3c and 3d that cover the headrest frame 30 and the cushion materials 3a and 3b. As shown in FIG. 2, the cushion material 3a is an elastic body made of an elastic material such as urethane. The second cushion material 3b is a three-dimensional mesh-like elastic body formed of three-dimensionally intertwined fibers. The second cushion material 3b functions as a cushioning material and also as a means of transmitting sound output from the speaker 5. The second cushion material 3b is not limited to a three-dimensional mesh elastic body as long as it is formed to have higher acoustic transparency than the cushion material 3a.

[0020] As shown in FIG. 2, the skin material 3c is a covering material made of a stretchable leather material or the like. The second skin material 3d is a covering material formed of three-dimensionally intertwined fibers. The second skin material 3d has both the function of a covering material and the function of allowing sound output from the speaker 5 to pass through. The second skin material 3d is not particularly limited as long as it is formed to have higher acoustic transparency than the skin material 3c.

[0021] In the above configuration, as shown in Fig. 2, the cushion portions of the cushion material that correspond to the left and right speakers 5 and microphone 6 in the front-rear direction of the seat are the second cushion material 3b, and the other cushion portions are the cushion material 3a. Furthermore, of the skin material, the skin portions corresponding to the left and right speakers 5 and microphone 6 in the front-rear direction of the seat are second skin material 3d, and the other skin portions are skin material 3c. This allows the sound generated from the speaker 5 to be transmitted to the outside more efficiently. Also, when the head of the seated occupant comes into contact with the headrest 3, it is possible to prevent the seated occupant from feeling uncomfortable. The cushion portion and the skin portion corresponding only to the speaker 5 may be the second cushion material 3b and the second skin material 3d, respectively. Alternatively, the entire cushion material and the entire cover material of the headrest 3 may be the second cushion material 3b and the second cover material 3d, respectively.

[0022] <Blower unit, speaker, microphone, control unit> 3 and 4, the blower device 4 is attached to the front of the upper part of the back frame 20. Specifically, it is attached to the front of the connecting frame 23 and the rear frame 24 of the back frame 20 via mounting brackets 27. The blower device 4 has a blower body 4a that supplies air, a duct 4b through which the air passes, and an outlet 4c that blows air toward the back of a seated person.

[0023] The blower body 4 a is disposed at the center of the upper part of the back frame 20 . The duct 4b extends from the blower main body 4a to the outside (right side) in the seat width direction, bends so as to surround the pillar 31, and extends toward the front of the seat. The outlet 4c is formed at the extending end of the duct 4b. The blower device 4 (blower main body 4a) is connected to the control device 7 via a blower harness 4d. The blower harness 4d extends from the blower main body 4a to the outside (left side) in the seat width direction, bends to surround the pillar 31, and extends downward.

[0024] 3 and 5, the speakers 5 are speaker units provided inside the headrest frame 30 and arranged on the left and right sides of the headrest frame 30. Specifically, the speakers 5 are attached to the left and right sides of the front surface of the rear cover 50 of the headrest frame 30 via speaker assembly bodies 70. The microphones 6 are microphone units, and are arranged on the left and right sides of the headrest frame 30 in the same manner as the speakers 5, and are attached to the left and right via speaker assemblies 70.

[0025] As shown in FIGS. 3, 8 to 10, the speaker 5 and the microphone 6 are connected to the control device 7 via a speaker harness 100A and a microphone harness 100B, respectively. The harnesses 100A and 100B extend inward in the seat width direction from the speaker 5 and the microphone 6, respectively, and are combined into a single harness 100, which passes through the inside of a pillar 31 (the left pillar 31) and extends downward. Details will be described later.

[0026] As shown in FIG. 1, the control device 7 is a device that controls electrical components, and is attached to the bottom surface of the cushion frame 10 via a holder (not shown). The control device 7 is electrically connected to the blower device 4 via a blower harness 4d and a harness 100. It is also electrically connected to the speaker 5 and the microphone 6 via the harness 100 (harnesses 100A and 100B). The control device 7 may be connected to these electrical components via wireless communication. The control device 7 is also connected to a battery (not shown) and controls the supply of electricity to the blower device 4, the speaker 5, and the microphone 6.

[0027] The control device 7 is externally connected to an external terminal, for example, a tablet terminal, a smartphone, a computer such as a PC, or an electric device, and receives a predetermined control signal (control information).Then, based on the control signal, the control device 7 controls the driving of the blower device 4, the speaker 5, and the microphone 6. The control device 7 may be attached to another location inside the vehicle seat S, or may be attached to the outside of the vehicle seat S.

[0028] <Seat frame> The cushion frame 10, not shown in the figures, is made up of a roughly rectangular frame-like body, cushion side frames arranged on the left and right sides and extending in the fore-and-aft direction of the seat, a pan frame installed in the front part of each cushion side frame, a connecting frame connecting the rear part of each cushion side frame, and a number of elastic springs hooked onto the pan frame and connecting frame and extending in a snake-like shape in the fore-and-aft direction of the seat. In this embodiment, the control device 7 is attached to the bottom surface of the cushion frame 10 (pan frame).

[0029] As shown in Figures 3 and 4, the back frame 20 is made of a substantially rectangular frame-like body and includes side frames 21 arranged on the left and right sides and extending in the vertical direction, an inverted U-shaped upper frame 22 connecting the upper end portions of each side frame 21, a lower frame (not shown) connecting the lower end portions of each side frame 21, a plate-shaped connecting frame 23 spanning the lower left and right portions of the upper frame 22 and extending in the seat width direction, and a plate-shaped rear frame 24 attached to the rear surface of the upper frame 22. The back frame 20 also includes left and right support wires 25 (occupant support wires) that are hooked to the connecting frame 23 and the lower frame and extend in the vertical direction, and an approximately rectangular support plate 26 (occupant support plate) that is positioned in the center of the back frame 20, is held by the left and right support wires 25, and supports the seated occupant from behind. The left and right side frames 21, the upper frame 22 and the lower frame correspond to the "frame-shaped main body frame."

[0030] A mounting bracket 27 for mounting the blower device 4 is further attached to the front surfaces of the connecting frame 23 and the rear frame 24 . More specifically, the central portion of the connecting frame 23 in the seat width direction has a recessed shape recessed toward the rear of the seat. The rear frame 24 is disposed so as to cover almost the entire upper frame 22 and the connecting frame 23 from the rear. The mounting bracket 27 is attached from the front of the seat in a partially fitted state to the front surface of the connecting frame 23, and is fixed to the connecting frame 23 and the rear frame 24 with a plurality of fastening bolts 28.

[0031] The mounting bracket 27 is disposed between the left and right pillars 31 and the rear frame 24 in the seat front-rear direction. The plurality of fastening bolts 28 are arranged so as to surround the blower device 4 (blower main body 4a) when viewed from the front of the seat. By doing so, the mounting rigidity of the blower device 4 can be increased.

[0032] A harness holding portion 24a for holding the harness 100 is formed at the lower end of the rear frame 24. In addition, a third harness mounting hole 24b (third harness mounting portion) for mounting a third mounting clip 103 (third mounted portion) provided on the harness 100 is formed at the front surface of the harness holding portion 24a. The harness holding portions 24a hang down from the lower end of the rear frame 24 and are formed at intervals in the seat width direction. The above configuration makes it possible to suitably hold the harness 100 extending from the speaker 5 and the microphone 6. It is also possible to prevent the harness 100 from interfering with other components.

[0033] Left and right pillar guides 29 for attaching left and right pillars 31 that serve as core materials for the headrest 3 are attached to the upper end of the upper frame 22 . The pillar guide 29 is a guide member that is fixed to the back frame 20 and holds the pillar 31 so that it can move up and down. The left and right pillar guides 29 are disposed at positions overlapping the mounting brackets 27 in the seat front-rear direction, and at positions different from the mounting brackets 27 in the seat width direction. Therefore, the design allows for compact placement of components while preventing them from interfering with each other.

[0034] As shown in Figures 3 and 5 to 7, the headrest frame 30 is mainly composed of an inverted U-shaped pillar 31 that serves as the core material of the headrest 3, a front cover 40 and a rear cover 50 that are respectively attached to the pillar 31 and positioned to sandwich the pillar 31 from the front-to-rear direction of the seat, and a lower cover 60 that is positioned to cover the pillar 31 from below. The front cover 40, rear cover 50 and lower cover 60 are arranged to cover the pillar 31, speaker 5, microphone 6 and speaker assembly 70 from the outside, and are assembled to each other. The front cover 40, the rear cover 50 and the lower cover 60 correspond to the "main body of the headrest."

[0035] As shown in Figures 5, 6 and 8, the pillar 31 is a cylindrical support member that supports the main body of the headrest 3, and is arranged at a predetermined interval in the seat width direction.It has left and right pillar extension portions 31a that extend downward from the main body of the headrest 3 toward the seat back 2, and a pillar connection portion 31b that connects the upper ends of the left and right pillar extension portions 31a and extends in the seat width direction. As shown in FIGS. 9A and 9B, a harness insertion hole 32 for passing the harness 100 is formed on the outer peripheral surface of the pillar 31 (left pillar extension 31a).

[0036] The harness insertion hole 32 is formed on the inner surface of the pillar extension portion 31a in the seat width direction, and has a reverse tapered cross section. This makes it easier to insert the harness through the pillar, and also prevents the harness from being unintentionally deformed. The cross-sectional shape of the harness insertion hole 32 may be tapered or linear.

[0037] As shown in FIGS. 3 and 10, a cylindrical cap member 33 that is more flexible than the metal pillar 31 is attached to the lower end of the pillar 31 (left pillar extension 31a). The cap member 33 is also called a pillar end cap and is, for example, a rubber cap that is detachably attached to the lower end of the pillar 31 from below. The cap member 33 has a support protrusion 33 a formed on its inner circumferential surface, which can be latched into a support groove 31 c provided on the outer circumferential surface of the pillar 31 . The cap member 33 is attached so as to cover the end face, inner face and outer face of the lower end of the pillar 31 in a state in which the cap member 33 is hooked into the support groove 31c by the support protrusion 33a. Therefore, when the harness 100 is exposed from the lower end of the pillar 31 , the harness 100 can be protected by the cap member 33 .

[0038] <Front cover> As shown in FIGS. 3 and 5 to 7, the front cover 40 is a cover made of resin, and is assembled integrally with the rear cover 50 and the lower cover 60. As shown in FIGS. More specifically, the front cover 40 is first assembled to the rear cover 50 in the seat front-rear direction, and then assembled to the lower cover 60 in the up-down direction.

[0039] The front cover 40 is a plate body that includes a front wall portion 40a, an upper wall portion 40b, left and right side wall portions 40c, and a bottom wall portion 40d. The front cover 40 also has a cover central portion 41 located in the center of the seat width direction, and left and right cover side portions 42 located on the left and right outer sides of the cover central portion 41 and protruding further forward of the seat than the cover central portion 41.

[0040] The front cover 40 has locking pieces 43 and locking holes 43a formed at the upper end and both left and right ends of its outer edge, which protrude rearward from the seat and can be locked to the rear cover 50 (locking claws 55). A first pillar latch recess 44 that protrudes rearward from the seat and can be attached to the rear cover 50 (first pillar latch clip 56) is formed at the upper end of the rear surface of the front cover 40. Also, left and right second pillar latch recesses 45 that can be attached to the rear cover 50 (left and right second pillar latch clips 57) are formed at the rear end of the bottom surface of the front cover 40. The front cover 40 has left and right assembly bosses 46 (assembly portions) formed in a lower portion of the front surface thereof so as to be recessed behind the seat and which can be assembled to the rear cover 50 (assembly holes 58).

[0041] With the above configuration, the front cover 40 is temporarily fixed to the rear cover 50 by the locking piece 43 (locking hole 43a) being detachably engaged with the locking claw 55 and the pillar latching recesses 44, 45 being detachably latched with the pillar latching clips 56, 57. The front cover 40 is then fully fixed to the rear cover 50 by bolting the assembly bosses 46 into the assembly holes 58 .

[0042] The bottom surface of the front cover 40 is provided with an engagement hole 47 that penetrates in the vertical direction and can be attached to the lower cover 60 (engagement hook 62). The front cover 40 has a lower end portion formed with a fixing hole 48 (fixing portion) that is formed to protrude downward and is fixed to the lower cover 60 (fixing boss 63).

[0043] With the above-described configuration, the front cover 40 is temporarily fixed to the lower cover 60 by the engagement holes 47 being detachably engaged with the engagement hooks 62 . The front cover 40 is fixed integrally to the lower cover 60 by fastening with bolts in a state in which the fixing bosses 63 are abutted against the fixing holes 48 . More specifically, the fixing bosses 63 are brought into contact with the fixing holes 48 of the front cover 40 and the fixing holes 59 of the rear cover 50, with the holes overlapping like a tally. Then, the front cover 40, rear cover 50, and lower cover 60 are fixed in place by fastening them with bolts.

[0044] As shown in FIGS. 3 and 7, the left and right cover side portions 42 have lattice-shaped openings 49 formed at positions corresponding to the left and right speakers 5 in the seat front-rear direction. The opening 49 is also called a speaker grill, and has a plurality of through holes for passing the sound output from the speaker 5. Although the opening 49 is formed in a lattice shape, it is not particularly limited, and may be formed in a mesh shape, and is not particularly limited as long as it is a shape that allows sound to pass through. As shown in FIG. 7, on the rear surface of the opening 49, a reinforcing rib 49a is formed along a lattice-shaped frame. The reinforcing rib 49a extends in the seat width direction and the up-down direction. The reinforcing rib 49a extending in the seat width direction is connected to the wall portion 41a (compartment wall portion) between the cover center portion 41 and the cover side portion 42.

[0045] <Rear cover> As shown in FIGS. 5, 6 and 8, the rear cover 50 is a resin cover, and is assembled integrally with the front cover 40 and the lower cover 60. As shown in FIG. The rear cover 50 is assembled to the front cover 40 in the seat front-rear direction, and then assembled to the lower cover 60 in the up-down direction. The rear cover 50 is a plate body that includes a rear wall portion 50a, an upper wall portion 50b, left and right side wall portions 50c, and a bottom wall portion 50d.

[0046] Left and right mounting bosses 51 (mounting portions) are formed at the upper end of the front surface of the rear cover 50, protruding forward of the seat and attachable to the speaker assembly 70 (left and right cover mounting holes 91). Also, left and right second mounting bosses 52 (second mounting portions) are formed at the lower end of the front surface of the rear cover 50, attachable to the speaker assembly 70 (left and right second cover mounting holes 85). Furthermore, a third mounting boss 53 (third mounting portion) is formed at the center of the front surface of the rear cover 50, attachable to the speaker assembly 70 (third cover mounting hole 92). The left and right second mounting bosses 52 are disposed outward from the left and right mounting bosses 51 in the seat width direction. The third mounting boss 53 is disposed inward from the left and right mounting bosses 51.

[0047] With the above configuration, the speaker assembly 70 is attached to the front surface of the rear cover 50. More specifically, the speaker assembly 70 (third cover mounting hole 92) is temporarily fixed to the rear cover 50 (third mounting boss 53). Then, the cover mounting holes 91, 85 are permanently fixed to the mounting bosses 51, 52 using mounting bolts.

[0048] A second harness attachment hole 54 for attaching the harness 100 (second attachment clip 102) is formed at the lower end of the front surface of the rear cover 50. This allows the rear cover 50 to hold the harness 100 in an appropriate manner.

[0049] The rear cover 50 has locking claws 55 (locking portions) formed on the upper end and both left and right ends of its outer edge, which protrude forward of the seat and can be locked onto the front cover 40 (locking pieces 43). First pillar latch clips 56 (first pillar latch portions) that protrude forward of the seat and can be assembled to the front cover 40 (first pillar latch recesses 44) are formed at the upper end of the front surface of the rear cover 50. Furthermore, left and right second pillar latch clips 57 (second pillar latch portions) that can be assembled to the front cover 40 (second pillar latch recesses 45) are formed at the front end of the bottom surface of the rear cover 50. The rear cover 50 has left and right assembly holes 58 (assembly receiving portions) formed in a lower portion of the front surface thereof so as to be recessed behind the seat and which can be assembled to the front cover 40 (left and right assembly bosses 46).

[0050] The pillar latch clip 56 is disposed at a position where it overlaps with the left and right mounting bosses 51 in the vertical direction. As shown in FIG. 8, the pillar latch clips 56, 57 are arranged at positions sandwiching the second mounting boss 52 and the third mounting boss 53 on the left and right sides in the vertical direction. The pillar latch clip 56 is disposed between the left and right mounting bosses 51, 52 in the seat width direction. The second pillar latch clip 57 is disposed between the left and right mounting bosses 52 in the seat width direction. The first pillar latching clip 56 is formed to sandwich the pillar 31 in the vertical direction, and the second pillar latching clip 57 is formed to sandwich the pillar 31 in the seat width direction.

[0051] With the above-described configuration, the pillar 31 and the front cover 40 are attached to the front surface of the rear cover 50. More specifically, first, the pillar 31 is latched to the rear cover 50 (pillar latching clips 56, 57). Then, the front cover 40 (latching pieces 43, pillar latching recesses 44, 45) is latched to the rear cover 50 (latching claws 55, pillar latching clips 56, 57). Then, the front cover 40 (assembly bosses 46) is bolted to the rear cover 50 (assembly holes 58). The pillar 31 is sandwiched between the front cover 40 (pillar latch recesses 44, 45) and the rear cover 50 (pillar latch clips 56, 57) in the seat front-rear direction.

[0052] In the above configuration, as shown in FIG. 8, when the pillar 31 is hooked to the pillar hook clips 56, 57, a gap filling member 34 is attached to fill the gap formed between the pillar 31 and the pillar hook clips 56, 57. The gap filling member 34 is a flexible (elastic) member. By interposing the gap filling member 34, rattle of the pillar 31 or the rear cover 50 can be suppressed. Furthermore, generation of abnormal noise between the pillar 31 and the rear cover 50 can be suppressed. The gap filling member 34 may be a nonwoven fabric, or may be a dowel, a rib, or a rib formed on the outer periphery of the pillar 31 or on the outer surface of the rear cover 50.

[0053] The rear cover 50 has a lower end portion formed with a fixing hole 59 (fixing portion) that protrudes downward and is fixed to the lower cover 60 (fixing boss 63). With the above-described configuration, the rear cover 50 is fixed to the lower cover 60 by fastening it with bolts while the fixing bosses 63 are in contact with the fixing holes 59 .

[0054] <Lower cover> As shown in Figures 3, 5, and 6, the lower cover 60 is a resin cover that is integrally assembled with the front cover 40 and the rear cover 50 and is positioned so as to cover the front cover 40 and the rear cover 50 from below. The lower cover 60 is a plate body having a curved shape that curves downward. Specifically, the outer edge portion of the lower cover 60 is formed so as to protrude upward.

[0055] Left and right pillar insertion holes 61 (pillar insertion portions) for passing the pillars 31 (left and right pillar extension portions 31a) are formed in the left and right side portions of the upper surface of the lower cover 60. By doing so, the lower cover 60 can be assembled to the pillar 31 hooked to the rear cover 50.

[0056] An engagement hook 62 is formed in the center of the upper surface of the lower cover 60, protruding upward and capable of detachably engaging with the front cover 40 (engagement hole 47). The upper surface of the lower cover 60 is formed with a plurality of fixing bosses 63 (fixed portions) that protrude upward and can be fixed to the front cover 40 (fixing holes 48) and the rear cover 50 (fixing holes 59). The fixing bosses 63 are arranged at intervals in the seat width direction so as to sandwich the engaging hook 62 therebetween. With the above-described configuration, the lower cover 60 is temporarily fixed to the front cover 40, and then fixed to the front cover 40 and the rear cover 50 with bolts.

[0057] <Speaker assembly> As shown in Figures 5, 6, 8, and 9A, the speaker assembly 70 is a resin box (housing) that is provided on the left and right sides of the headrest 3 and has left and right speaker holding portions 80 that hold the left and right speakers 5 (microphones 6) exposed to the front side of the seat, and a connecting portion 90 that connects the left and right speaker holding portions 80 and is formed integrally with the left and right speaker holding portions 80. The term "integrally formed" includes a state in which the speaker holding portion 80 and the connecting portion 90 are integrally molded, as well as a state in which they are integrated by welding, etc. Furthermore, it also includes a state in which they are assembled to each other without the need for a separate mounting member (mounting plate, mounting bolt, etc.).

[0058] The speaker assembly 70 is arranged so that the left and right speaker holding portions 80 cover the pillar 31 from both sides in the seat width direction, and the connecting portion 90 covers the pillar 31 from the rear side of the seat. This makes it possible to prevent the speaker assembly 70 and the speaker 5 from shaking (moving) in the left-right and front-rear directions relative to the headrest 3 (pillar 31) while the vehicle is traveling, for example.

[0059] As shown in Figures 5, 6, and 8, the speaker holding portion 80 has the function of accommodating the speaker 5 and the microphone 6, and the function of accommodating the harnesses 100 connected to the speaker 5 and the microphone 6, respectively. The speaker holding portion 80 has a central wall portion 80a, protruding wall portions (upper wall portion 80b, bottom wall portion 80c, side wall portion 80d) that protrude from the outer edge portion of the central wall portion 80a toward the front of the seat, and extending wall portions (rear upper wall portion 80e, rear bottom wall portion 80f, left and right rear side wall portions 80g) that extend from the outer edge portion of the central wall portion 80a toward the rear of the seat. The speaker holder 80 further has second extending walls (a lower front wall 80h, a flange wall 80i, and a reinforcing wall 80j) extending downward from the rear bottom wall 80f.

[0060] In the above configuration, as shown in Figures 5 and 11, the upper wall portion 80b protrudes forward from the upper end of the main body (central wall portion 80a) of the speaker holder 80. The bottom wall portion 80c protrudes forward from the lower end of the central wall portion 80a. The side wall portion 80d protrudes forward from the side end (right end) of the central wall portion 80a. The front ends of each of the side wall portions 80d abut against the rear surface of the front cover 40. This allows the front cover 40 to be suitably supported by the speaker assembly 70 when an external load is applied from the front side of the seat. These wall portions 80b, 80c, and 80d do not necessarily have to abut against the front cover 40, but may be arranged so as to be able to abut against the front cover 40.

[0061] As shown in Figures 5, 6, and 8, the speaker holding portion 80 has a storage recess 81 located at a forward position thereof for storing the speaker 5 and the microphone 6, a rear storage recess 82 located at a rear position of the speaker holding portion 80 for storing the harness 100, and a lid portion 83 that covers the rear storage recess 82 from behind the seat. The speaker 5 and the microphone 6 are housed in the housing recess 81 from the front side of the seat and are held in a state where they are exposed on the front side of the seat. More specifically, the speaker 5 is housed so as to penetrate the housing bottom surface of the housing recess 81, and is held in a state in which it is exposed to the front and rear sides of the seat from the speaker holding portion 80. The microphone 6 is housed in a recess 81a provided in the housing bottom surface of the housing recess 81, and is held in a state in which it is exposed to the front side of the seat from the speaker holding portion 80. More specifically, the speaker 5 penetrates through the bottom surface of the storage recess 81 and the bottom surface of the rear storage recess 82 in the seat front-rear direction. In other words, the speaker 5 is housed in the storage recess 81 and the rear storage recess 82.

[0062] In the above configuration, as shown in Figures 8 and 11, the speaker holding portion 80 holds the speaker 5 in a state where it is exposed on the front side of the seat, and also holds the microphone 6 in a state where it is exposed on the front side of the seat at a position below the speaker 5. The speaker 5 and the microphone 6 are disposed between the upper end of the mounting boss 51 and the lower end of the connecting portion 90 in the vertical direction. This allows the rear cover 50 , the speaker assembly 70 , the speaker 5 and the microphone 6 to be firmly attached to the pillar 31 that serves as the core material of the headrest 3 .

[0063] The harness 100A connected to the speaker 5 and the harness 100B connected to the microphone 6 are housed in the rear housing recess 82. The rear housing recess 82 is covered by a lid 83 from the rear of the seat. 6, bolt holes 82a and 83a are formed in the lower end of the rear accommodating recess 82 and the lower end of the lid 83. The lid 83 is attached to the rear accommodating recess 82 by attaching a fixing bolt with the bolt holes 82a and 83a communicating with each other. As shown in FIGS. 6 and 9A, the extending end portions of the harnesses 100A and 100B extend from gaps formed on the inner side surfaces of the rear accommodating recess 82, protruding inward in the seat width direction.

[0064] In the above configuration, as shown in FIG. 8, a chamfered portion 84 is formed at the corner of the accommodation recess 81 (the corner at the inner lower end). This can increase the rigidity of the accommodating recess 81. Also, interference between the accommodating recess 81 and other components can be suppressed.

[0065] In the above configuration, as shown in Figures 5 and 8, the lower end of the speaker holding portion 80 is formed with left and right second cover mounting holes 85 that can be attached to the rear cover 50 (left and right second mounting bosses 52). The second cover attachment hole 85 is disposed directly below the speaker 5 and the microphone 6. The second cover attachment hole 85 is also disposed outside the pillar 31 in the seat width direction.

[0066] As shown in Figures 5, 6, 8, and 9A, the connecting portion 90 is a connecting bracket that is long in the seat width direction, and is the part that assembles the speaker assembly 70 to the pillar 31, and also the part that holds the harness 100 extending from the speaker 5 (microphone 6). The connecting portion 90 has a rear wall portion 90a that extends longitudinally in the seat width direction and connects the left and right speaker holding portions 80, an upper wall portion 90b that extends from the upper end of the rear wall portion 90a toward the front of the seat, and a front wall portion 90c that extends upward from the front end of the upper wall portion 90b.

[0067] The upper end of the connecting portion 90 (front wall portion 90c) is formed with left and right cover mounting holes 91 that can be attached to the rear cover 50 (left and right mounting bosses 51). Furthermore, a third cover mounting hole 92 that can be attached to the rear cover 50 (third mounting boss 53) is formed in the center of the connecting portion (rear wall portion 90a).

[0068] On the rear surface of the connecting portion 90 (front wall portion 90c), harness guide portions 93 and 94 are formed so as to protrude rearward of the seat and to guide the harness 100. The harness guide portion 93 and the second harness guide portion 94 are arranged side by side in the seat width direction, and are arranged at a position facing the rear accommodating recess 82. The harness guide portions 93 and 94 are U-shaped, and support the harness 100 from above, below and in front after the harness 100 is attached from the rear of the seat.

[0069] As shown in Figures 8 and 9A, a plurality of harness mounting holes 95 are formed on the front surface of the central portion of the connecting portion 90 (rear wall portion 90a) for mounting mounting clips 101 provided on the harness 100 to support the harness 100. As shown in FIG. 9A, a reinforcing rib 96 extending longitudinally along the extension direction of the connecting portion 90 is formed on the rear surface of the connecting portion 90 (rear wall portion 90a) at a position above the harness attachment hole 95. As shown in Figures 5, 8, and 12, abutment ribs 97 are formed on the front surfaces of the left and right side portions of the connecting portion 90 (rear wall portion 90a), protruding forward of the seat toward the pillar 31 and abutting against the rear surface of the pillar 31.

[0070] As shown in FIGS. 8 and 9A, a plurality of harness attachment holes 95 are arranged in a row in the seat width direction. The reinforcing ribs 96 extend outward on the left and right sides of the harness attachment holes 95 in the seat width direction, and protrude toward the opposite side (rear side of the seat) from the harness 100 side (front side of the seat). Therefore, when forming the reinforcing rib 96 around the harness attachment hole 95, the reinforcing rib can be arranged while suppressing interference between the harness 100 and the reinforcing rib 96.

[0071] As shown in FIG. 8, the contact ribs 97 are formed on the left and right sides at a predetermined interval in the seat width direction. The left and right contact ribs 97 are arranged so as to sandwich the harness attachment hole 95 therebetween. In detail, the abutment rib 97 has a first abutment rib 97a and a second abutment rib 97b arranged at a distance in the vertical direction, and a connecting rib 97c connecting the first abutment rib 97a and the second abutment rib 97b. As shown in FIG. 12, the first contact rib 97a, the second contact rib 97b, and the connecting rib 97c each come into contact with the rear surface of the pillar 31. The contact rib 97 does not necessarily have to contact the pillar 31, but may be disposed so as to be able to contact the pillar 31.

[0072] <Harness> 6 and 8 to 10, the harnesses 100A and 100B extend inward in the seat width direction from the speaker 5 and the microphone 6, respectively, and are combined into a single harness 100, which passes through the inside of a pillar 31 (the left pillar 31) and extends downward toward the seat back 2. The harness 100 then extends further from the seat back 2 toward the seat cushion 1 and is connected to a control device 7 provided in the seat cushion 1.

[0073] Each of the harnesses 100A and 100B has a mounting clip 101 that can be attached to the speaker assembly 70 (harness mounting hole 95). More specifically, the harnesses 100A and 100B have a coupler at a position facing the harness mounting hole 95, and the coupler has a mounting clip 101 attached to it. The harness 100 also has a second attachment clip 102 that can be attached to the rear cover 50 (second harness attachment hole 54). The harness 100 is provided inside the seat back 2 and has a third attachment clip 103 that can be attached to the rear frame 24 (third harness attachment hole 24b). The harness 100 is provided inside the seat back 2 and has a harness guide 104 that covers the harness 100 (harness main body).

[0074] The routing of the harness 100 will be described in detail below with reference to FIGS. 3, 6, and 8 to 10. FIG. The harness 100A (100B) is connected to the speaker 5 (microphone 6) and is housed in the rear housing recess . The harness 100A extending from the speaker 5 extends from the rear accommodation recess 82 inward in the seat width direction and is supported by the harness guide portions 93 and 94. The harness 100A extends downward from the harness guide portions 93, 94 and is supported by the harness attachment hole 95. Specifically, an attachment clip 101 is attached to the harness attachment hole 95. The harness 100A and the harness 100B extend downward and are combined into a single harness 100.

[0075] The single harness 100 is supported by the second harness mounting hole 54. Specifically, the second mounting clip 102 is attached to the rear cover 50 (the second harness mounting hole 54). The harness 100 then extends from the second harness mounting hole 54 toward the pillar 31 (left pillar extension 31a) on one side in the seat width direction (left side). The harness 100 is passed through a harness insertion hole 32 provided in the pillar 31 and into the interior of the pillar 31, and extends downward toward the seat back.

[0076] The harness 100 exposed from the lower end of the pillar 31 extends to the right side in the seat width direction, then folds back and extends to the left side in the seat width direction along the lower end of the rear frame 24. At this time, the harness 100 is held by a plurality of harness holding portions 24a at the lower end of the rear frame 24. The harness 100 is also supported by a third harness mounting hole 24b at the lower end of the rear frame 24. Specifically, a third mounting clip 103 is attached to the third harness mounting hole 24b.

[0077] Inside the seat back 2, the harness 100 and the blower harness 4d are bundled together and extend downward toward the seat cushion 1. The single harness 100 is connected to a control device 7 provided inside the seat cushion 1.

[0078] In the above configuration, as shown in Fig. 9A, harnesses 100A and 100B extend respectively from the speaker 5 and the microphone 6. It is possible to take measures to prevent these harnesses 100A and 100B from being assembled incorrectly. For example, the thickness of the harness 100A connected to the speaker 5 and the thickness of the harness 100B connected to the microphone 6 may be different. That is, the thickness of the harness 100A may be made thicker or thinner than the thickness of the harness 100B. For example, the coupler (connector) of the harness 100A and the coupler (connector) of the harness 100B may have different shapes, sizes, colors, or marks. As different marks, the harness 100A may have a mark "S (Speaker)" and the harness 100B may have a mark "M (Microphone)."

[0079] In the above configuration, as shown in FIGS. 9A and 9B, the left and right harnesses 100 are gathered into one and passed through the interior of the left pillar 31. On the other hand, as a modified example, the harness 100 connected to the left speaker 5 may extend from the left speaker toward the pillar 31 and be passed through the inside of the pillar 31 via the harness insertion hole 32 provided in the left pillar extension portion 31a. The harness 100 connected to the right speaker 5 may be passed through the inside of the pillar 31 via the harness insertion hole 32 provided in the right pillar extension portion 31a.

[0080] <Method for manufacturing vehicle seats> Next, manufacturing methods 1 and 2 of the vehicle seat S will be described with reference to FIGS. 13A to 13C and 14A to 14C. In addition, in the method for manufacturing the vehicle seat S, explanation of manufacturing steps other than those described below will be omitted. 13A to 13C, in "Manufacturing Method 1," first, the speaker 5 and microphone 6 are assembled to the speaker assembly 70. Specifically, the speaker 5 is assembled to the speaker holding portion 80 (accommodation recess 81) and fixed with an adhesive or assembly bolts. The microphone 6 is also assembled to the recess 81a.

[0081] The speaker assembly 70 is then attached to the rear cover 50. Specifically, the cover attachment holes 91, 85, 92 are attached to the left and right attachment bosses 51, 52, 53. More specifically, the cover attachment holes 91, 85 are bolted to the attachment bosses 51, 52. The third cover attachment hole 92 is hooked onto the third attachment boss 53 for temporary fixation. Then, the pillar 31 is hooked to the rear cover 50. Specifically, the pillar 31 is hooked to the pillar hook clips 56 and 57. Then, the harness 100 is passed through the interior of the pillar 31. Then, the front cover 40 is assembled to the rear cover 50, and with the front cover 40 and the rear cover 50 assembled, the lower cover 60 is assembled from below.

[0082] In "Manufacturing Method 2," first, the speaker 5 and the microphone 6 are assembled to the speaker assembly 70, as shown in FIGS. 14A to 14C. Then, the speaker assembly 70 is "temporarily fixed" to the rear cover 50. Specifically, the third cover mounting holes 92 are hooked onto the third mounting bosses 53 to temporarily fix the speaker assembly 70. Then, the pillar 31 is hooked onto the rear cover 50. At this time, the speaker assembly 70 is pressed against the rear cover 50 by the pillar 31. Then, the speaker assembly 70 is "finally fixed" to the rear cover 50. Specifically, the cover mounting holes 91, 85 are fixed to the mounting bosses 51, 52 with bolts.

[0083] Then, the harness 100 is passed through the interior of the pillar 31. Then, the front cover 40 is assembled to the rear cover 50, and with the front cover 40 and the rear cover 50 assembled, the lower cover 60 is assembled from below.

[0084] According to the above configuration, a vehicle seat S in which the speaker 5 can be easily attached to the headrest 3 can be realized. Furthermore, it is possible to realize a vehicle seat S in which the structure of the speaker assembly 70 for assembling the speaker 5 can be made simpler than in the past. Also, a method for manufacturing a vehicle seat S can be realized.

[0085] <Other embodiments> In the above embodiment, as shown in FIG. 5, the headrest frame 30 includes the front cover 40, the rear cover 50, and the lower cover 60, but this is not particularly limited. For example, the lower cover 60 may be omitted, or the front cover 40 or the rear cover 50 may be omitted.

[0086] In the above embodiment, as shown in FIGS. 5 and 6, the engagement holes 47 of the front cover 40 and the engagement hooks 62 of the lower cover 60 are engaged with each other, but the engagement structure is not particularly limited. For example, the engagement holes 47 may be replaced with engagement recesses. In addition, for example, the engagement structure may be changed to one other than the engagement holes and engagement hooks. In other words, the engaged portion of the front cover 40 and the engaging portion of the lower cover 60 may be engaged with each other by other engagement structures. In addition, in the above embodiments, the structures of the locking portion and locked portion, the mounting portion and mounted portion, the assembly portion and assembled portion, the fixing portion and fixed portion, etc. may also be changed as appropriate.

[0087] In the above embodiment, as shown in FIGS. 5 and 6, the left and right speaker holding portions 80 and the connecting portion 90 are integrally formed in the speaker assembly 70, but this is not particularly limited. The left and right speaker holding portions 80 and the connecting portion 90 may be formed separately, that is, the speaker holding portions 80 and the connecting portion 90 may be connected via an attachment member.

[0088] In the above embodiment, as shown in FIGS. 5 and 6, the speaker holding portion 80 has the accommodating recess 81 and the rear accommodating recess 82, but it may have only one of the accommodating recesses. For example, the speaker holding portion 80 may have only the rear housing recess 82 (housing recess) and may house the speaker 5, the microphone 6, and the harness 100. In this case, the speaker 5 and the microphone 6 may be disposed so as to penetrate the housing bottom surface of the rear housing recess 82 and be exposed on the front side of the seat.

[0089] In the above embodiment, a vehicle seat used in an automobile was described as a specific example, but the present invention is not limited to this and can also be used as a vehicle seat for trains, buses, etc., as well as airplanes, ships, etc.

[0090] In this embodiment, the vehicle seat according to the present invention has been mainly described. However, the above embodiment is merely an example for facilitating understanding of the present invention, and does not limit the present invention. The present invention can be modified and improved without departing from the spirit thereof, and the present invention naturally includes equivalents thereof. [Explanation of symbols]
