Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, vehicle seats such as those in Patent Documents 1 and 2 include a plurality of linear members (for example, cables and harnesses) having different hardnesses. If these linear members are grouped together and assembled into one module, since the hardness and material are different between the cable and the harness, there is a possibility that their performance may be affected by interference with each other.

[0005] An object of the present invention is to provide a vehicle seat capable of appropriately holding a plurality of linear members by a module. Another object of the present invention is to provide a vehicle seat that can suppress interference between linear members when multiple linear members are assembled and held in a module. [Means for solving the problem]

[0006] The aforementioned problem is solved by the vehicle seat of the present invention, which comprises a vehicle seat having a seat body, a linear first linear member provided on the seat body, a linear second linear member provided on the seat body having a different hardness from the first linear member, and a module provided on the seat body that holds the first linear member and the second linear member, wherein the module has a module body, a first holding portion provided on the first surface or the side of the first surface of the module body that holds the first linear member, and a second holding portion provided on the second surface or the side of the second surface of the module body opposite to the first surface that holds the second linear member. With the above configuration, a vehicle seat can be realized that can appropriately hold multiple linear members using modules. More specifically, in the above-mentioned vehicle seat, the module has a first holding portion provided on the first surface side of the module body for holding a first linear member, and a second holding portion provided on the second surface side opposite to the first surface side of the module body for holding a second linear member. This allows a single module to hold both the first linear member and the second linear member, which has a different hardness from the first linear member, thereby preventing these linear members from interfering with each other.

[0007] In this case, the first linear member is a cable for operating a functional component provided on the sheet body, the second linear member is a harness for operating an electrical component provided on the sheet body, and the first holding portion is preferably positioned to overlap with the second holding portion when viewed from a direction perpendicular to the first surface of the module body, or when viewed from a direction perpendicular to the second surface of the module body. The above configuration allows cables and harnesses to be held in a way that prevents them from interfering with each other. Furthermore, it allows for a compact arrangement even when cables and harnesses are positioned in different locations.

[0008] In this case, the module may have a coupler holding portion provided on the second surface or on the second surface side, which holds the harness connection portion provided at the end of the harness. The above configuration prevents the harness connector (coupler) at the end of the harness from interfering with other components.

[0009] In this case, the seat body comprises a seat frame that forms the skeleton, the seat frame has a support plate that supports the occupant from below or behind, the module has a plate engagement portion provided on the module body that engages with an engagement portion formed on the surface of the support plate, and the first holding portion is preferably arranged in the module body between a plurality of the plate engagement portions. With the above configuration, the first linear member held by the first holding portion is surrounded by the plate engagement portion, making it easier to suppress interference between the first linear member and other components.

[0010] In this case, the module has a blower holding portion provided on the second surface or the side of the second surface of the module body, which holds a blower that blows air toward the seated person, and the second holding portion is preferably provided on the outer edge portion of the blower holding portion. With the above configuration, the number of components can be reduced by giving the module the function of holding a blower in addition to the function of holding a linear member.

[0011] In this case, the sheet body is provided with a blower having a blower that blows out air and a duct connected to the blower, and the blower and the duct are arranged on the second surface or the second surface side of the module body, and the module body has a duct passage section formed therein for the duct to pass from the second surface side to the first surface side. The above configuration suppresses interference between modules and ducts, allowing for optimal duct placement.

[0012] In this case, it is preferable that the module body has a recess for housing a blower that blows air toward the seated person. The above configuration allows for a compact housing of the blower. Furthermore, it makes it easier to identify the blower's mounting position when assembling it into the module.

[0013] In this case, the receiving recess is formed on the second surface or on the second surface side of the module body, and it is preferable that the blower does not protrude from the second surface side of the module when the blower is housed in the receiving recess. The above configuration allows the blower to be compactly integrated into the module. Furthermore, because the blower does not protrude from the module, interference between the blower and other components can be suppressed.

[0014] In this case, the sheet body is provided with a blower that blows out air, and it is preferable that the blower is positioned between the module body and the support plate. With the above configuration, the blower can be properly protected by the module and support plate.

[0015] In this case, the seat body has a cushion frame that serves as the skeleton, and the cushion frame has left and right side frames arranged at intervals in the width direction of the seat, a front connecting frame connecting the front portions of the left and right side frames, a rear connecting frame connecting the rear portions of the left and right side frames, and a support plate that spans between the left and right side frames, the front connecting frame, and the rear connecting frame, and the module is assembled on the back surface of the support plate, the first holding portion is arranged between the support plate and the module body and holds the first linear member, and the second holding portion is arranged on the opposite side of the module body from the first holding portion and holds the second linear member. With the above configuration, a plurality of linear members disposed on the bottom surface of the seat cushion can be appropriately held by the module. That is, it is possible to prevent the plurality of linear members from interfering with each other.

[0018] Hereinafter, embodiments of the present invention will be described with reference to Figures 1 to 10. This embodiment relates to a "vehicle seat" that enables the appropriate holding of multiple linear members by a module. Furthermore, when it comes to vehicle seats, the side on which the occupant sits is the front side (front of the seat) relative to the seat back. Also, the side on which the occupant sits is the upper side (upper side of the seat) relative to the seat cushion.

[0019] <Vehicle seats> As shown in Figure 1, the vehicle seat S is a vehicle seat, for example, a front seat positioned at the front of the vehicle. The vehicle seat S may also be a middle seat or a rear seat. As shown in Figure 2, the vehicle seat S is equipped with a seat frame F that forms its framework.

[0020] As shown in Figures 1 to 3, the vehicle seat S comprises a seat body Sa having a seat cushion 1, a seat back 2, and a headrest 3; a rail device 4 that supports the seat body Sa so as to be movable forward and backward relative to the vehicle floor; and a reclining device 5 that rotatably connects the seat back 2 to the seat cushion 1. Furthermore, the vehicle seat S includes a detection sensor 6 that detects the occupant's biosignals, a vibration device 7 that applies vibrations to the occupant, air blowers 40 and 80 that blow air towards the occupant, and a control device 90 that controls the vibration device 7 and the air blowers 40 and 80.

[0021] The rail device 4 and the reclining device 5 are considered "functional components" and are connected to cables 30 and 70, as shown in Figures 3 and 6. The detection sensor 6, vibration device 7, blower 40, second blower 80, and control device 90 are all "electrical components" that operate electrically and are connected to harnesses 35 and 75. Furthermore, if the rail device 4 and the reclining device 5 are electrically operated, these parts also fall under the category of "electrical components." Similarly, the vibration device 7 and the blower devices 40 and 80 also fall under the category of "functional components."

[0022] As shown in Figures 3 and 6, cables 30 and 70 correspond to the "first linear members," while harnesses 35 and 75 correspond to the "second linear members," which have a different hardness from the first linear members. Cable 30 and harness 35 are held by module 20 and assembled in a manner that suppresses interference between linear members. Similarly, cable 70 and harness 75 are held by second module 60.

[0023] As shown in Figures 1 and 2, the seat cushion 1 is a seating portion that supports the occupant from below, and comprises a cushion frame 10 that forms the skeleton, a pad material 1a placed on the cushion frame 10, and a surface material 1b that covers the cushion frame 10 and the pad material 1a. A detection sensor 6 and a vibration device 7 are positioned between the pad material 1a and the surface material 1b of the seat cushion 1. Additionally, a blower 40 and a control device 90 are attached to the bottom surface of the cushion frame 10 of the seat cushion 1. Furthermore, on the back surface of the pad material 1a, slightly to the right, an insertion hole is formed for inserting the duct 42 and outlet 43 of the blower 40 shown in Figure 2. On the surface of the pad material 1a, concave ventilation holes are formed throughout, communicating with this insertion hole.

[0024] As shown in Figures 1 and 6, the seat back 2 is a backrest that supports the occupant from behind, and comprises a back frame 50 that forms the skeleton, a pad material 2a, and a surface material 2b. A second ventilation device 80 is attached to the rear surface of the back frame 50 of the seat back 2. Furthermore, on the back surface of the pad material 2a, slightly towards the center, an insertion hole is formed for inserting the duct 82 and outlet 83 of the second blower 80 shown in Figure 6. On the surface of the pad material 2a, concave ventilation holes that communicate with this insertion hole are formed throughout.

[0025] As shown in Figure 1, the headrest 3 is a head section that supports the occupant's head from behind, and comprises a head pillar that forms the frame, a pad material 3a, and a surface material 3b that covers the head pillar and the pad material 3a.

[0026] As shown in Figures 1 to 3, the rail device 4 is positioned vertically between the seat cushion 1 and the vehicle floor. The rail device 4 includes left and right lower rails 4a fixed to the vehicle floor and extending in the front-rear direction of the seat, left and right upper rails 4b slidably supported along the lower rails 4a, a locking member 4c that locks the upper rails 4b to the lower rails 4a so that they cannot slide, and a rail operating lever that releases the locked state of the locking member 4c. The rail operating lever is attached, for example, to the front right end of the seat cushion 1 and is connected to the locking member 4c and cable 30 shown in Figure 3. As shown in Figure 2, cushion frames 10 are attached to the upper surfaces of the left and right upper rails 4b via rail brackets.

[0027] As shown in Figures 1 and 2, the reclining device 5 includes a reclining body 5a that is driven when the seat back 2 is rotated, a back rotation axis 5b, a spiral spring 5c ​​that biases the seat back 2 to rotate forward around the back rotation axis 5b, and a reclining operation lever that is operated to release the lock on the seat back 2. The reclining unit 5a can switch the state of the seat back 2 between a "locked state" in which it is fixed to the seat cushion 1 and an "unlocked state" in which it can rotate relative to the seat cushion 1. The back pivot shaft 5b is pivotally supported in the seat width direction by the cushion frame 10 and the back frame 50 (side connecting frame 57). The spiral spring 5c ​​has one end locked to the cushion frame 10 and the other end locked to the back frame 50. The reclining control lever is attached, for example, to the left shoulder portion of the seat back 2 and is connected to the reclining unit 5a shown in Figure 6 by a cable 70.

[0028] As shown in Figure 1, the detection sensor 6 is a sheet-shaped sensor installed inside the seat cushion 1 that detects whether a person is seated there. For example, the detection sensor 6 is a biosensor that detects the seated person's biological signals (respiratory signals) and outputs a detection signal to the control device 90. Specifically, the detection sensor 6 is a planar pressure sensor that detects the seating pressure of the seated person. "Seating pressure" is a value that changes periodically in response to the physiological activity (breathing) of a person when they are seated, and is detected by the detection sensor 6. The detection sensor 6 may be a sensor other than a pressure sensor.

[0029] The detection sensor 6 is positioned between the pad material 1a and the surface material 1b of the seat cushion 1 and is housed in a storage recess (not shown) formed in the pad material 1a. Vibration devices 7 are attached to both the left and right sides of the detection sensor 6.

[0030] As shown in Figure 1, the vibration device 7 is a vibration motor that applies a physical force to the seated person, and is a functional component that starts vibrating upon receiving a control signal from the control device 90. The vibration device 7 can apply physical stimulation to the seated person's buttocks or thighs through vibration. The vibration device 7, like the detection sensor 6, is mounted between the pad material 1a and the surface material 1b. The left and right vibration devices 7 are positioned with the detection sensor 6 in between.

[0031] <<Cushion frame, module, linear member>> As shown in Figures 2 and 3, the cushion frame 10 consists of a rectangular frame-like body and includes side frames 11 arranged on the left and right sides and extending in the front-rear direction, a plate-shaped pan frame 12 installed on the front end of each side frame 11, a front connecting frame 13 connecting the front portions of each side frame 11, a rear connecting frame 14 connecting the rear portions (rear end portions) of each side frame 11, a plurality of wire members 15 that are hooked onto the front connecting frame 13 and the rear connecting frame 14 and extend in the front-rear direction, and a support plate 16 supported by the plurality of wire members 15.

[0032] A holder 12a for housing the control device 90 is assembled on the back surface of the central portion of the pan frame 12 in the sheet width direction. The holder 12a detachably holds the control device 90. The front connecting frame 13 and the rear connecting frame 14 are, for example, pipe-shaped frames.

[0033] As shown in Figures 2 to 4, the support plate 16 is a support member that supports the buttocks of a seated person, and is also called a pressure receiving plate. The support plate 16 is positioned in the area enclosed by the left and right side frames 11, the front connecting frame 13, and the rear connecting frame 14. The support plate 16 has a rectangular plate body portion 16a, a duct insertion hole 16b formed on the surface of the plate body portion 16a for inserting the duct 42, and a plurality of engagement holes 16c formed at intervals on the surface of the plate body portion 16a for engaging with the module 20 (plate engagement portion 22).

[0034] The duct insertion hole 16b is located opposite the duct 42 of the blower 40 and is a hole that penetrates the plate body 16a. The duct insertion hole 16b is also called a duct guide hole or a duct holding hole. The engagement hole 16c is an engaged portion that detachably engages the module 20, and is a hole that penetrates the plate body portion 16a. The engagement hole 16c engages with the plate engagement portion 22 (engagement projection) of the module 20. As a result, as shown in Figure 4, the module 20 is detachably assembled to the back surface of the support plate 16. To remove the module 20 from the support plate 16, the engagement can be released by pulling the module 20 downwards from the support plate 16.

[0035] Module 20 is a resin holder module that separately holds the cable 30 and harness 35, as shown in Figures 3 to 5. Module 20 has the function of holding the cable 30 and harness 35, and the function of holding the blower 40. Module 20 is assembled to the back surface of support plate 16.

[0036] Module 20 comprises a rectangular plate-shaped module body 21, a plurality of plate engagement parts 22, a duct passage part 23, a pair of first holding parts 24, a blower holding part 25, a pair of second holding parts 26, a pair of third holding parts 27, and coupler holding parts 28, 29.

[0037] As shown in Figures 3 and 4, the plate engagement portion 22 is an engagement projection that protrudes from the surface of the module body 21 and engages with the support plate 16 (engagement hole 16c) in a vertically detachable manner. As shown in Figure 3, the plate engagement portion 22 is positioned at the corner of the module body 21 and at the portion of the module body 21 corresponding to the blower 40.

[0038] The duct passage section 23 is an opening or hole formed at a position opposite the duct 42, and is formed at the corner (front right corner) of the module body 21. Specifically, the duct passage section 23 is a notched hole formed in the corner of the module body 21.

[0039] The first holding portion 24 is provided on the surface side (first surface side) of the module body 21 and is a portion (hooking portion) that holds the cable 30 (first linear member), and is formed in pairs. The first retaining portion 24 protrudes upward from the surface of the module body 21 and is positioned between the support plate 16 and the module body 21 in the vertical direction. Specifically, as shown in Figure 4, the first retaining portion 24 has an L-shaped cross-section and comprises a first wall portion 24a that protrudes upward from the surface of the module body 21, and a second wall portion 24b that extends outward in the front-rear direction from the protruding end of the first wall portion 24a.

[0040] The first holding part 24 holds the cable 30 together with the module body 21 so as to surround it. More specifically, the first holding portion 24 holds the cable 30 by surrounding it with the module body 21 and the plate engagement portion 22. Furthermore, as shown in Figure 4, a pair of first holding parts 24 are formed at a predetermined distance apart and facing opposite directions. This allows the pair of first holding parts 24 to hold the cable 30 in a way that wraps around (bundles) it, as shown in Figure 3.

[0041] As shown in Figures 3 and 4, the blower holding portion 25 is provided on the back side (second side) of the module body 21 and is the part (cover portion) that holds the blower 41. The blower holder 25 has a housing recess 25a for housing the blower 41, and a second housing recess 25b that extends from a part of the housing recess 25a to one side for housing the connection portion between the blower 41 and the duct 42. When the blower 41 is housed in the recesses 25a and 25b, it is positioned so that it does not protrude from the surface of the module 20. In other words, the surface of the blower 41 and the surfaces of the recesses 25a and 25b are flush (or nearly flush). As shown in Figures 2 and 3, the duct 42 protrudes horizontally from the blower holding section 25 to one side (forward), bends upward, passes through the duct passage section 23 and the support plate 16 (duct insertion hole 16b), and extends outwards to the surface side of the support plate 16.

[0042] The second holding portion 26 is provided on the back side (second surface side) of the module body 21 and is a portion (hooking portion) that holds the harness 35 (second linear member), and is formed in pairs. The second holding portion 26 protrudes laterally from the outer edge of the blower holding portion 25 and is positioned below the support plate 16. Specifically, as shown in Figure 4, the second holding portion 26 has an L-shaped cross-section and comprises a first wall portion 26a that protrudes laterally from the outer surface of the blower holding portion 25, and a second wall portion 26b that extends upward from the protruding end of the first wall portion 26a.

[0043] The second holding part 26 holds the harness 35 together with the blower holding part 25 so as to surround it. More specifically, the second holding part 26 holds the harness 35 by surrounding it with the module body 21 and the blower holding part 25. Furthermore, as shown in Figure 4, a pair of second holding parts 26 are formed at a predetermined distance apart and facing opposite directions. This allows the harness 35 to be held by the pair of second holding parts 26 in a way that wraps around (bundles) it, as shown in Figure 3.

[0044] As shown in Figures 3 and 5, the third retaining portion 27 is provided on the surface side (first surface side) of the module body 21 and is positioned at a distance from the first retaining portion 24. The third holding portion 27, like the first holding portion 24, is a portion (hooking portion) that holds the cable 30 (first linear member), and is formed in pairs. The third retaining portion 27 protrudes upward from the surface of the module body 21 and is positioned between the support plate 16 and the module body 21 in the vertical direction. Specifically, as shown in Figure 5, the third retaining portion 27 has an L-shaped cross-section and comprises a first wall portion 27a that protrudes upward from the surface of the module body 21, and a second wall portion 27b that extends outward in the front-rear direction from the protruding end of the first wall portion 27a.

[0045] The third holding part 27 holds the cable 30 together with the module body 21 so as to surround it. As shown in Figure 5, a pair of third holding portions 27 are formed spaced apart and facing opposite directions. The pair of first holding portions 24 can hold the cable 30 by wrapping it around them. As shown in Figure 3, the first holding part 24 and the third holding part 27 are positioned at the same height in the vertical direction and at the same position in the front-to-back direction. In other words, the first holding part 24 and the third holding part 27 are arranged side by side.

[0046] As shown in Figures 3 and 5, the coupler holding portion 28 is provided on the back side (second side) of the module body 21 and is the portion (hooking portion) that holds the harness 35 (second linear member). The coupler holding parts 28 and 29 protrude downward from the module body 21 and are arranged with a gap between them in the front-to-back direction. Specifically, as shown in Figure 5, the coupler holding portion 28 has a U-shaped cross-section and comprises a base wall portion 28a that is attached to the module body, left and right side wall portions 28b that protrude downward from both ends of the base wall portion 28a, and support wall portions 28c that extend inward from the protruding ends of the left and right side wall portions 28b.

[0047] The coupler holder 28 holds the harness 35 together with the module body 21 so as to surround it. The second coupler retaining portion 29 is positioned differently from the coupler retaining portion 28 and, like the coupler retaining portion 28, holds the harness 35 in a manner that surrounds it. As a result, as shown in Figure 3, the harness 35 can be held by the second holding part 26 and the coupler holding parts 28 and 29 in a way that wraps around (bundles) it.

[0048] Cable 30 is a linear first linear member, as shown in Figures 3 to 5. Cable 30 is a cable for operating functional components, for example, connecting the locking member 4c of the rail device 4 to the rail operating lever. One end of cable 30 extends toward the rail operating lever located at the right front end of the seat cushion 1, and the other end of cable 30 extends toward the locking member 4c located at the left rear end of the seat cushion 1. In this case, the crew operates the rail operation lever to pull the cable 30. As the cable 30 is pulled, the locking member 4c is activated and the locked state of the locking member 4c is released. Furthermore, the cable 30 may also be a cable for operating functional components other than the rail device 4 (such as the reclining device 5, height device, side support device, etc.).

[0049] The cable 30 is held in place from below by the module 20. Specifically, as shown in Figures 3 to 5, the cable 30 is positioned between the support plate 16 and the module 20 in the vertical direction and is held by the first holding part 24 and the third holding part 27. The cable 30 is held in place by the module 20, so that it does not interfere with the harness 35 and is positioned without hanging down.

[0050] As shown in Figures 3 to 5, the harness 35 is a second linear member with a different hardness (physical properties) from the cable 30. The harness 35 is a wire harness for operating electrical components, for example, connecting the vibration device 7 and the control device 90. One end of the harness 35 is connected to the control device 90 located on the underside of the pan frame 12, and the other end of the harness 35 is connected to the vibration device 7 located in the rear part of the seat cushion 1. Furthermore, as shown in the bottom view of the seat cushion 1 in Figure 3, one end and the other end of the harness 35 are held in the module 20 (coupler holding part 28) before being connected to the electrical components.

[0051] Couplers 35a and 35b (harness connection parts), which serve as connection terminals, are attached to one end and the other end of the harness 35, respectively. Coupler 35a is held by the coupler holding portion 28, and coupler 35b is held by the second coupler holding portion 29. The harness 35 is held in place by the module 20, so that it does not interfere with the cable 30 and is positioned without hanging down. The harness 35 may also be a harness for connecting electrical components other than the vibration device 7 and the control device 90.

[0052] As shown in Figures 2 to 4, the blower 40 is a device that blows air towards the seated person. Alternatively, instead of a fan, a device that draws in air from the seated side may also be used. The blower 40 is mounted on the back surface of the support plate 16 via a module 20 (blower holding part 25).

[0053] The blower 40 includes a blower 41, a duct 42 connected to the blower 41 for passing air, and a nozzle 43 (air outlet) connected to the duct 42 for blowing out air. The harness 35 is electrically connected to the blower 41 (the side portion of the blower 41).

[0054] The blower 41 is housed in the blower holder 25 and is held from below by the blower holder 25. Specifically, as shown in Figure 4, the blower 41 is provided surrounded by the module body 21 and the blower holding part 25. It can also be said that the blower 41 is positioned between the support plate 16 and the module body 21 (blower holding part 25) in the vertical direction. When assembling the blower 41, it is preferable to first house the blower 41 inside the blower holder 25, and then assemble the blower holder 25 containing the blower 41 to the module body 21. The blower 41 has a blower body and a blower connection part extending from the blower body. A duct 42 is connected to the blower connection part.

[0055] As shown in Figures 2 and 3, the duct 42 is an air pipe connecting the blower 41 and the outlet 43, extending forward from the blower 41 (blower connection part), bending upward, and passing through the support plate 16 and the pad material 1a to extend upward. Specifically, the duct 42 has a first duct extension 42a that is connected to the blower 41 and extends forward, and a second duct extension 42b that bends upward from the extension end of the first duct extension 42a and extends upward.

[0056] The first duct extension 42a extends in the front-rear direction along the bottom surface of the module 20. The second duct extension 42b passes through the duct passage 23 of the module 20 and extends upward through the duct insertion hole 16b of the support plate 16. The second duct extension 42b further extends through the insertion hole in the pad material 1a. The air outlet 43 is located at the tip of the second duct extension 42b and is exposed on the surface of the pad material 1a.

[0057] With the above configuration, the blower 40 can send air from the blower 41 and blow it out from the outlet 43 through the duct 42. As a result, the blower 40 can blow air towards the seated person. Furthermore, the blower 40 is properly held in place by the module 20 (blower holding section 25).

[0058] In the above configuration, as shown in Figures 3 and 4, the first retaining portion 24 is provided on the first surface (front) of the module body 21, and the second retaining portion 26 is provided on the second surface (back) of the module body 21, which is on the opposite side from the first surface. This allows a single module 20 to hold both the cable 30 and the harness 35, thereby preventing interference between these linear components.

[0059] In the above configuration, as shown in Figure 4, the first retaining portion 24 is positioned to overlap with the second retaining portion 26 when viewed from a direction perpendicular to the first surface (front surface) of the module body 21, and when viewed from a direction perpendicular to the second surface (back surface) of the module body 21. In other words, the first retaining portion 24 and the second retaining portion 26 are positioned to overlap when viewed from above and below the sheet. Furthermore, as shown in Figure 5, the third retaining portion 27 is positioned horizontally, sandwiching the coupler retaining portion 28 between them. This allows the cable 30 and harness 35 to be positioned in different locations while maintaining a compact overall design.

[0060] In the above configuration, as shown in Figure 4, the first retaining portion 24 is positioned between a plurality of plate engaging portions 22 in the module body 21. As a result, the cable 30 held by the first retaining portion 24 is surrounded by the plate engaging portion 22. Therefore, interference between the cable 30 and other components is more easily suppressed.

[0061] <<Back frame, second module, linear member>> As shown in Figures 2 and 6, the back frame 50 consists of a rectangular frame-like body and comprises back side frames 51 arranged on the left and right sides, an upper frame 52 connecting the upper ends of each back side frame 51, a lower frame 53 connecting the lower ends of each back side frame 51, and a connecting frame 54 connecting the upper portions of each back side frame 51. Furthermore, the back frame 50 includes a plurality of wire members 55 that are hooked onto the connecting frame 54 and the lower frame 53 and extend in the vertical direction, a support plate 56 supported by the plurality of wire members 55, and a side connecting frame 57 attached to the lower end of the back side frame 51. The side connecting frame 57 is a frame that connects the side frame 11 and the back side frame 51.

[0062] As shown in Figures 6 and 7, the support plate 56 is a support member that supports the back of the seated person. The support plate 56 has a rectangular plate body portion 56a and a plurality of engagement holes 56c that engage with the second module 60 (plate engagement portion 62).

[0063] The engagement hole 56c is an engaged portion that detachably engages the second module 60, and is a hole that penetrates the plate body portion 56a. The engagement hole 56c engages with the plate engagement portion 62 (engagement projection) of the second module 60. As a result, the second module 60 is detachably assembled to the back surface of the support plate 56, as shown in Figure 6.

[0064] The second module 60 is a resin holder module that separately holds the cable 70 and harness 75, as shown in Figures 6 to 8. The second module 60 has the function of holding the cable 70 and harness 75, and the function of holding the second blower 80. The second module 60 is assembled to the back surface of the support plate 56.

[0065] The second module 60 comprises a module body 61, a plurality of plate engagement portions 62, a pair of first holding portions 64, a blower holding portion 65, a pair of second holding portions 66, a pair of third holding portions 67, and a coupler holding portion 68.

[0066] As shown in Figures 6 and 7, the plate engagement portion 62 is an engagement projection that protrudes from the surface of the module body 61 and engages with the support plate 56 (engagement hole 56c) in a front-to-back direction so as to be detachable. As shown in Figure 6, the plate engagement portion 62 is positioned at the corner of the module body 61 and at the portion of the module body 61 corresponding to the second blower 80.

[0067] The first holding portion 64 is provided on the front side (first surface side) of the module body 61 and is a portion that holds the cable 30 (first linear member), and is formed in pairs. The first retaining portion 64 protrudes forward from the surface of the module body 61 and is positioned between the support plate 56 and the module body 61. Specifically, as shown in Figure 7, the first retaining portion 64 has an L-shaped cross-section and comprises a first wall portion 64a and a second wall portion 64b. The first holding part 64 holds the cable 70 together with the module body 61 so as to surround it. More specifically, the first retaining portion 64 holds the cable 70 by surrounding it with the module body 61 and the plate engaging portion 62.

[0068] As shown in Figures 6 and 7, the blower holding portion 65 is provided on the back side (second side) of the module body 61 and is a cover portion that holds the blower 81. The blower holder 65 has a housing recess 65a for housing the blower 81.

[0069] The second retaining portion 66 is provided on the back side (second side) of the module body 61 and is a hook portion for holding the harness 75, and is formed in pairs. The second retaining portion 66 protrudes laterally from the outer edge of the blower retaining portion 65 and is positioned behind the support plate 56. Specifically, as shown in Figure 7, the second retaining portion 66 has an L-shaped cross-section and comprises a first wall portion 66a and a second wall portion 66b.

[0070] The second holding part 66 holds the harness 75 together with the blower holding part 65 so as to surround it. More specifically, the second holding part 26 holds the harness 75 by surrounding it with the module body 61 and the blower holding part 65.

[0071] As shown in Figures 6 and 8, the third retaining portion 67 is provided on the surface side (first surface side) of the module body 61 and is positioned at a distance from the first retaining portion 64. The third retaining portion 67, like the first retaining portion 64, is a hook portion for holding the cable 70, and is formed in pairs. The third retaining portion 67 has an L-shaped cross-section and comprises a first wall portion 67a and a second wall portion 67b.

[0072] As shown in Figures 6 and 8, the coupler holding portion 68 is provided on the back side (second side) of the module body 61 and is a latching portion that holds the harness 75. The coupler holder portion 68 protrudes downward from the module body 61. The coupler retaining portion 68 holds the harness 75 in a manner similar to the coupler retaining portion 28, surrounding it.

[0073] As shown in Figures 6 to 8, cable 70 is a cable for operating functional components, for example, connecting the reclining body 5a and the reclining operation lever of the reclining device 5. One end of cable 70 extends toward the reclining body 5a located at the lower right end of the seat back 2, and the other end of cable 70 extends toward the reclining operation lever located at the upper left end of the seat back 2. Note that cable 70 may be a cable that operates a functional component other than the reclining device 5.

[0074] The cable 70 is positioned between the support plate 56 and the second module 60 in the front-rear direction and is held from the rear by the second module 60. The cable 70 is held in place by the second module 60, so that it does not interfere with the harness 75 and is positioned without hanging down.

[0075] As shown in Figures 6 to 8, harness 75 is a wire harness for operating electrical components, and for example, connects the second blower 80 and the control device 90. Furthermore, as shown in the rear view of the seat back 2 in Figure 6, one end and the other end of the harness 75 are held in the second module 60 (coupler holding part 68) before being connected to the electrical components.

[0076] The second blower 80 is a device that blows air towards the seated person, as shown in Figures 6 to 8. The second blower 80 is assembled to the back surface of the support plate 56 via the second module 60 (blower holding part 65). The second blower 80 includes a blower 81, a duct 82, and a discharge port 83. The blower 81 is electrically connected to harness 75.

[0077] The blower 81 is housed in the blower holder 65. When assembling the blower 81, it is preferable to first house the blower 81 inside the blower holder 65, and then assemble the blower holder 65 containing the blower 81 to the module body 61.

[0078] The duct 82 extends upward from the blower 81, bends forward, and extends forward, passing through the support plate 56 and the pad material 2a. Specifically, the duct 42 has a first duct extension 42a that is connected to the blower 41 and extends forward, and a second duct extension 42b that bends upward from the extension end of the first duct extension 42a and extends upward. The outlet 83 is located at the tip of the duct 82 and is exposed on the surface of the pad material 2a.

[0079] <<Control device>> As shown in Figures 1 and 2, the control device 90 is a device that comprehensively controls the electrical operation of the vehicle seat S, and is, for example, an engine control unit (ECU). The control device 90 is connected to the detection sensor 6, vibration device 7, blower 40, second blower 80, and other electrical components by harnesses 35 and 75. The control device 90 is mounted to the back of the central part of the seat cushion 1 (pan frame 12) via a bracket.

[0080] The control unit 90, in terms of its hardware configuration, is a general-purpose ECU consisting of a CPU (processor) for calculation control, RAM and ROM as storage devices, and a communication interface for sending and receiving information data. The control device 90 receives, for example, the biological signals of the seated person detected by the detection sensor 6 and determines the seated person's state of alertness. If it determines that the seated person is not alert, it sends a signal to the vibration device 7 to activate it. The control device 90 may also determine the fatigue level of the seated person and control the vibration device 7 to drive based on that fatigue level.

[0081] <Variation> Next, we will explain the 1st to 4th modified examples of the vehicle seat S based on Figures 9A to 9D. Note that we will omit explanations of content that overlaps with the vehicle seat S described above.

[0082] <<Example 1>> As shown in Figure 9A, the modified vehicle seat S1 comprises a seat cushion 1 (cushion frame 10), a plate-shaped module 20, a cable 30, a harness 35, and a blower 40. The cushion frame 10 has a support plate 16. The support plate 16 has a plate body portion 16a and a plurality of engagement holes 16c that engage with the module 20 (plate engagement portion 22). Module 20 includes a module body 21, a plurality of plate engagement portions 22, a pair of first holding portions 24, a blower holding portion 25, and a pair of second holding portions 26.

[0083] The module body 21 has a recess 21a for housing the blower 41 and the harness 35. A first retaining portion 24 is formed on the outer edge of the recess 21a. A blower retaining portion 25 and a second retaining portion 26 are provided inside the recess 21a.

[0084] The first retaining portion 24 is provided on the outer edge of the recess 21a of the module body 21 and is a portion that holds the cable 30, and is formed in pairs. The first retaining portion 24 is positioned between the support plate 16 and the module body 21 in the vertical direction, and between the multiple plate engagement portions 22 in the horizontal direction. The first holding portion 24 holds the cable 30 by surrounding it with the module body 21 and the plate engagement portion 22.

[0085] The blower holding portion 25 is provided on the back surface of the module body 21 (recess 21a) and is a cover portion that holds the blower 41. The blower holder 25 has a housing recess 25a for housing the blower 41.

The second retaining portion 26 protrudes laterally from the outer edge of the blower retaining portion 25 and is positioned inward from the first retaining portion 24. The second holding section 26 holds the harness 35 by surrounding it with the module body 21 and the blower holding section 25. The harness 35 is assembled to the second retaining part 26 from below the module 20.

[0092] As shown in Figure 9B, the plate engagement portion 22, the first holding portion 24, the blower holding portion 25, and the second holding portion 26 are arranged side by side at the same height. This allows the module 20 to be configured to suppress interference between the cable 30 and the harness 35, and also allows the components of the module 20 to be arranged compactly.

[0093] <<Modification 3>> As shown in Figure 9C, the modified vehicle seat S3 comprises a seat cushion 1 (cushion frame 10), a plate-shaped module 20, a cable 30, a harness 35, and a blower 40.

[0094] The module body 21 has a recess 21a for housing the blower 41 and the harness 35. A first retaining portion 24 is formed on the outer edge of the recess 21a. A blower retaining portion 25 and a second retaining portion 26 are provided inside the recess 21a.

[0095] The first retaining portion 24 is provided on the outer edge of the recess 21a of the module body 21 and is a portion that holds the cable 30, and is formed in pairs. The first retaining portion 24 is provided on the back surface of the module body 21 and is positioned horizontally between a plurality of plate engaging portions 22. The first holding part 24 holds the cable 30 together with the module body 21 so as to surround it.

[0096] The blower holding portion 25 is a cover portion provided on the surface of the module body 21 (recess 21a) and holds the blower 41. The blower holder 25 has a housing recess 25a for housing the blower 41. An opening for housing the blower 41 is formed on the upper surface of the housing recess 25a.

[0097] The second holding portion 26 is provided on the surface of the module body 21 and is a portion that holds the harness 35, and is formed in pairs. The second retaining portion 26 protrudes laterally from the outer edge of the blower retaining portion 25 and is positioned inward from the first retaining portion 24. The second holding section 26 holds the harness 35 by surrounding it with the support plate 16 and the blower holding section 25. The harness 35 is assembled to the second retaining part 26 from above the module 20.

[0098] As shown in Figure 9C, the first holding part 24, the blower holding part 25, and the second holding part 26 are arranged side by side at the same height. This allows the module 20 to be configured to suppress interference between the cable 30 and the harness 35, and also allows the components of the module 20 to be arranged compactly.

[0099] <<Modification 4>> As shown in Figure 9D, the modified vehicle seat S4 comprises a seat cushion 1 (cushion frame 10), a plate-shaped module 20, a cable 30, a harness 35, and a blower 40.

[0100] The module body 21 has a recess 21a for housing the blower 41 and the harness 35. A first retaining portion 24 is formed on the outer edge of the recess 21a. A blower retaining portion 25 and a second retaining portion 26 are provided inside the recess 21a.

[0101] The blower holding portion 25 is a cover portion provided on the surface of the module body 21 (recess 21a) and holds the blower 41. The blower holder 25 has a housing recess 25a for housing the blower 41. An opening for housing the blower 41 is formed on the upper surface of the housing recess 25a.

[0102] The second holding portion 26 is provided on the surface of the module body 21 and is a portion that holds the harness 35, and is formed in pairs. The second retaining portion 26 protrudes laterally from the outer edge of the blower retaining portion 25 and is positioned inward from the first retaining portion 24. The second holding section 26 holds the harness 35 by surrounding it with the module body 21 and the blower holding section 25. The harness 35 is assembled to the second retaining part 26 from below the blower retaining part 25.

[0103] As shown in Figure 9D, the first holding part 24, the blower holding part 25, and the second holding part 26 are arranged side by side at the same height. This allows the module 20 to be configured to suppress interference between the cable 30 and the harness 35, and also allows the components of the module 20 to be arranged compactly.

[0104] With the above-mentioned vehicle seat S, it becomes possible to appropriately hold multiple linear members using modules. Specifically, when multiple linear members are assembled and held in a module, interference between the linear members can be suppressed.

[0105] Figure 10 is a bottom view of the seat cushion 1, showing the state in which the module cover is separately assembled to the bottom surface of the module 20. In this way, by assembling the module cover 120 to the bottom surface of the module 20, the cables 30 and harnesses 35 held by the module can be covered from below. As a result, the module cover 120 can effectively receive the cables 30 and harnesses 35 that hang down from the parts held by the module 20. As shown in Figure 10, the module cover 120 includes a cover body 120a, a cover opening 120b formed in the cover body 120a, and a cover locking portion 120c provided at the corner of the cover body 120a. The cover opening 120b is positioned opposite the blower 40. The cover locking portion 120c is detachably locked to the locking portion 21b of the module 20.

[0106] <Manufacturing method for vehicle seats> Next, the manufacturing method for the vehicle seat S will be explained based on Figures 1 to 8. Regarding the manufacturing method of the vehicle seat S, explanations of manufacturing processes other than those listed below will be omitted.

[0107] First, prepare the seat body Sa, which has a seat cushion 1 and a seat back 2, the cable 30, the harness 35, and the module 20. Then, module 20 is attached to the support plate 16 of seat cushion 1. Then, the cable 30 and harness 35 are attached to the module 20 which is mounted on the support plate 16.

[0108] At this time, it is preferable to assemble the cable 30 so that it is held by the first holding portion 24 located on the front side (first surface side) of the module body 21. Furthermore, it is preferable to assemble the harness 35 so that it is held in place by the second retaining part 26 located on the back side (second side) of the module body 21.

[0109] The above manufacturing method makes it possible to produce a vehicle seat that can appropriately hold multiple linear members using modules.

[0110] <Note> In the above configuration, the vehicle seat comprises a seat body, a flexible linear member (harness) provided on the seat body, and an electrical component provided on the seat body. This electrical component has a holding portion capable of holding the linear member. It is preferable that this holding portion be provided in a different location from the connector that connects the harness to the electrical component. This eliminates the need to separately prepare a holding part for the linear members, thus reducing the number of components in the sheet.

[0111] In the above configuration, the electrical component is a blower having a blower and a duct, the holding part has a housing groove, and the linear member is preferably arranged inside the housing groove. This allows the holding portion of the electrical component to easily hold the linear member.

[0112] In the above configuration, the holding portion preferably has an outer wall portion that covers the linear member from the outside. This allows for effective protection of the linear member.

[0113] In the above configuration, the vehicle seat has a module for assembling a blower (air blower) to the seat body, and the retaining part is preferably located in a housing recess formed in the module. This allows the retaining part to be positioned inside the recessed area, thereby properly protecting the harness held by the retaining part.

[0114] In the above configuration, the receiving recess is configured to be recessed toward the seat occupant side of the seat body, and the blower is preferably positioned on the opposite side of the module from the seat occupant side. This prevents the harness from being positioned on the seated side of the module. Therefore, interference between the seated person and the harness can be suppressed.

[0115] In the above configuration, it is preferable that the receiving groove is recessed in the opposite direction to the receiving recess. This allows the harness to be sandwiched between the bottom surface of the receiving groove and the bottom surface of the receiving recess. As a result, the harness can be protected more effectively.

[0116] In the above configuration, it is desirable that the bottom surface of module 20 (the opening surface of the blower holding portion 25) and the bottom surface of blower 41 be flush (or nearly flush). This allows the module 20 and the blower 41 to be arranged compactly in the vertical direction.

[0117] <Other> In the above embodiment, as shown in Figures 3 to 5, the first linear member is a cable 30 and the second linear member is a harness 35, but it is not limited to cables or harnesses and can be broadly applied as long as it is a linear member. For example, the linear member may be a tube that allows air to pass through.

[0118] In the above embodiment, a "coating portion" that covers a linear member such as a cable 30 or a harness 35 may be further provided. In this case, it is preferable that a retaining part such as a hook-and-loop fastener be attached to the outer surface of the "coating portion". By doing so, the hook-and-loop fastener (retained portion) provided on the outer surface of module 20 can be engaged with the hook-and-loop fastener (retaining portion) provided on the outer surface of the linear member. As a result, the linear member can be easily assembled to and held in module 20.

[0119] In the above embodiment, as shown in Figures 3 and 4, the first retaining portion 24 is provided on the surface of the module body 21 and the second retaining portion 26 is provided on the back surface of the module body 21, but this is not particularly limited. For example, the first retaining portion 24 may be provided on the back surface of the module body 21, and the second retaining portion 26 may be provided on the front surface of the module body 21.

[0120] In the above embodiment, a vehicle seat (automobile seat) was described as a specific example, but it is not particularly limited and can be used as a seat for vehicles such as trains and buses, as well as for vehicles such as airplanes and ships.

[0121] The above embodiments mainly described a vehicle seat according to the present invention. However, the embodiments described above are merely examples to facilitate understanding of the present invention and do not limit it. The present invention can be modified and improved without departing from its spirit, and of course, equivalents thereof are included. [Explanation of symbols]
