[0005] Patent Document 1: Japanese Patent Application Publication No. 2018-114183

[0006] In the above-mentioned prior art, the space separated by the partition is too wide, so it is difficult to form a comfortable personal space. In addition, the partition cannot follow the reclining action of the seat back and the sliding action of the seat, so the convenience is poor. Therefore, the present invention provides a partition device that can appropriately separate the surroundings. Summary of the invention

[0007] In order to solve the above-mentioned problems, the partition device of the present invention adopts the following means.

[0008] That is, the partition device of the present invention is a partition device that is provided on a seat and has a partition piece on one side that separates the seat from an adjacent seat. The partition piece is configured to have a rear panel and a side panel and does not cover the seated person from the front, top, bottom, and other side, the rear panel is mounted on at least one of the seat back and the headrest of the seat and covers the seated person's head from the rear, and the side panel extends forward from the rear panel through one side and covers the seated person's head from one side. The rear panel has a first concave curved surface, which is the inner circumference of a three-dimensional curved surface in which the upper portion and the two side portions are bent forward and become concave at the front. The side panel has a second concave curved surface, which is the inner circumference of a three-dimensional curved surface in which the upper portion and the front and rear portions are bent toward the other side in a manner that is smoothly continuous with the first concave curved surface and becomes concave at the other side.

[0009] According to the above structure, by using a partition composed of a rear panel and side panels having concave curved surfaces with three-dimensional curves that are smoothly continuous with each other, a partition that can ensure a comfortable personal space can be formed around the head of the seated person, enclosing the head from the back and one side in a wider and arc-shaped shape.

[0010] Furthermore, the partition device of the present invention may be configured as follows: The partition device further includes a blower having a blower that blows out wind from the rear to the front along the second concave curved surface.

[0011] According to the above structure, the air blown out by the blowing unit can form an air curtain blown forward along the second concave curved surface of the side panel. In addition, the air curtain can be bent along the curve of the second concave curved surface to approach the front side of the head of the seated person, thereby forming a more effective air curtain.

[0012] Furthermore, the partition device of the present invention may be configured as follows. The partition device further includes an air duct fixed in a shape extending from the blow-out portion toward the second concave curved surface along the first concave curved surface in the seat width direction, and conveying the wind blown out from the blower. The air duct itself or between the air duct and the first concave curved surface forms a closed cross-sectional shape.

[0013] According to the above structure, the partition member can be rationally reinforced through the air duct.

[0014] Furthermore, the partition device of the present invention may be configured as follows: The partition device further includes a louver plate attached to the second concave curved surface so as to bend the direction of the wind blown out from the blower toward the other side.

[0015] According to the above configuration, the wind direction can be adjusted such that the wind blown out from the blower unit blows toward the seated person's face from the side or toward the front of the face.

[0016] Furthermore, the partition device of the present invention may be configured as follows: The partition device further includes a rearward air duct that conveys the wind blown out from the blower so as to be blown out rearward from an opening provided in the rear panel.

[0017] According to the above configuration, the air can be blown out rationally also toward the rear of the partition material by the air outlet portion provided in the partition device.

[0018] Furthermore, the partition device of the present invention can also be constructed as follows. The partition member further comprises an extension panel, which is fixed to the rear panel and extends from at least one of the upper edge of the rear panel and the side edge of the other side in a manner flush with the rear panel. The extension panel is softer than the rear panel.

[0019] According to the above configuration, the soft expansion panel fixed around the rear panel can expand the shape of the partition member in a manner that allows interference with surrounding structures such as the vehicle ceiling and the vehicle side wall.

[0020] Furthermore, the partition device of the present invention may be configured as follows. The partition device further includes a speaker unit, and the speaker unit is mounted on the first concave curved surface. The rear panel includes a speaker recess, and the speaker recess is formed by recessing a portion of the first concave curved surface toward the rear in order to form a housing behind the speaker unit.

[0021] According to the above configuration, the housing of the speaker unit mounted on the partition member can be rationally formed by utilizing the structure of the partition member.

[0022] Furthermore, the partition device of the present invention may be configured as follows: The partition device further includes a speaker unit facing rearward, and the speaker unit facing rearward is mounted on the rear surface of the rear panel.

[0023] According to the above configuration, even if the seat and the space behind the seat are partitioned by the partition, the sound directed toward the rear can be outputted through the speaker unit directed toward the rear mounted on the rear panel.

[0024] It should be noted that, as the sound outputted by the speaker unit facing rearward, in addition to the sound outputted from the audio device installed in the vehicle, there can also be exemplified the sound emitted by the seat occupant outputted by a microphone provided at a predetermined position such as the side panel of the seat, etc. By using the speaker unit facing rearward to output the sound through the microphone, communication between the seat occupant separated by the partition and the outside can be smoothly performed.

[0025] Furthermore, the partition device of the present invention can also be configured as follows. A flat surface serving as a mounting seat surface for accessories is formed on the rear surface of the rear panel. Examples of the accessories include various electrical components such as displays, tablet terminals, lighting fixtures, auxiliary handles that can be used by seat occupants of the rear seats, seat back tables that are deployed to the rear of the seat backs, cup holders, and the like.

[0026] According to the above configuration, the flat surface serving as the attachment seat surface can be rationally formed by utilizing the structure of the rear panel that partitions the seat from the space behind the seat.

[0027] Furthermore, the partition device of the present invention can also be configured as follows: The partition member has a three-dimensional curved outer peripheral surface along the inner peripheral surfaces of the rear panel and the side panel, and has a reinforcing rib on the outer peripheral surface, and the reinforcing rib extends in a rib-like manner along the outer peripheral surface in the seat width direction.

[0028] According to the above structure, the wind flowing from the front to the rear on one side of the partition is guided to flow behind the rear panel of the partition due to the wall effect along the outer peripheral surface of the partition. At that time, the wind flowing to the rear is rectified in a manner that is difficult to diffuse in the height direction by the rib-shaped reinforcing ribs formed on the outer peripheral surface of the partition. Therefore, the wind flowing to the rear can be appropriately guided to the back of the rear panel of the partition. BRIEF DESCRIPTION OF THE DRAWINGS

[0071] 《First Implementation Mode》

[0072] (About the schematic structure of the partition device 4)

[0073] First, use Figures 1 to 11 The structure of the partition device 4 of the first embodiment of the present invention is described. It should be noted that in the following description, when the directions such as front, back, top, bottom, left, and right are shown, they refer to the directions shown in the respective figures. Also, when it is indicated as "seat width direction", it refers to the left and right direction of the seat 1 described later. Also, in the following description, when a specific reference figure is not shown or when there is no reference number in the reference figure, appropriate reference is made to Figures 1 to 11 Any of the graphs in .

[0074] like Figure 1 As shown, the partition device 4 of this embodiment is applied to the right front seat 1 of a two-row seat vehicle. The partition device 4 is structured to include a panel-shaped partition member 10 that partitions the seat 1 from a left seat (not shown).

[0075] The partition member 10 is attached to the rear surface of a seat back 2 constituting a backrest of the seat 1. The seat 1 includes a seat back 2 constituting a backrest of a seated person, a seat cushion (not shown) constituting a seat portion, and a headrest 3 constituting a headrest portion.

[0076] The lower ends of the left and right sides of the seat back 2 are connected to the rear ends of the left and right sides of the seat cushion via recliners (not shown). Thus, the seat back 2 is configured to be recline-adjustable so that the backrest angle of the seat back 2 can be changed forward and backward. The headrest 3 is mounted on the upper part of the seat back 2.

[0077] Furthermore, a seat cushion (not shown) is connected to the floor of the vehicle via a seat lifter (not shown). Thus, the seat 1 is configured to be able to adjust the height relative to the floor.

[0078] The partition member 10 is mounted on the upper rear surface of the seat back 2. The partition member 10 is configured to include a rear panel 11, a side panel 12, and an extension panel 13. The rear panel 11 is configured to stand up from the upper rear surface of the seat back 2 and cover the head of the seated person and its surroundings from the rear in a wide planar shape. More specifically, the rear panel 11 is configured to cover the headrest 3 and its surroundings from the rear in a wide planar shape.

[0079] The side panel 12 is configured to extend forward from the rear panel 11 through the left side (one side) and cover the head of the seated person and its surroundings from the left side in a wide planar shape. More specifically, the side panel 12 is configured to extend forward from the rear panel 11 through the left side (one side) of the headrest 3 and the seat back 2 and cover the head of the seated person and its surroundings from the left side in a wide planar shape. The rear panel 11 and the side panel 12 are configured as a panel material composed of a synthetic resin such as acrylic resin, polycarbonate resin, etc.

[0080] Specifically, if Figures 1 to 11 As shown, the rear panel 11 is formed into a curved panel shape having a first concave curved surface 11A, the upper portion and the left and right side portions of the first concave curved surface 11A are curved forward, and the first concave curved surface 11A is an inner peripheral surface of a three-dimensional curved surface that becomes concave in the front. In addition, the side panel 12 is formed into a curved panel shape having a second concave curved surface 12A, the upper portion and the front and rear portions of the second concave curved surface 12A are curved to the right in a manner that is smoothly continuous with the first concave curved surface 11A, and the second concave curved surface 12A is an inner peripheral surface of a three-dimensional curved surface that becomes concave to the right.

[0081] With the above structure, the partition member 10 is formed into a curved panel shape, and the curved panel shape forms a three-dimensional concave curved surface in which the rear panel 11 and the side panel 12 are smoothly continuous with each other. Figure 3 As shown, the rear panel 11 is formed into a panel shape in which the width thereof tapers upward in a mountain shape.

[0082] And, if Figure 4 as well as Figure 5 As shown, the partition member 10 is formed into a panel shape with the front edge of the side panel 12 bulging forward in an arc shape. Through the above structure, the partition member 10 is configured to form a space around the head of the seated person that can ensure a comfortable personal space by enclosing the head from the back and left in a wide and arc shape.

[0083] The partition member 10 partitions the seat 1 from not only the left seat but also the rear seat (not shown). The partition member 10 is configured not to cover the seated person from the front, top, bottom and right.

[0084] like Figure 1 to Figure 3 As shown, the expansion panel 13 is arranged to be integrally arranged over the entire upper edge area and the entire right edge area of ​​the rear panel 11. The expansion panel 13 is composed of a panel material composed of a synthetic resin such as silicone resin, elastomer resin, etc., which is softer than the rear panel 11 and the side panel 12.

[0085] The expansion panel 13 is fixed to the upper edge and right side edge of the rear panel 11 by screws not shown. By this fixing, the expansion panel 13 extends from the upper edge and right side edge of the rear panel 11 in a manner flush with the rear panel 11, expanding the panel shape of the rear panel 11 into a shape that is enlarged upward and to the right.

[0086] The expansion panel 13 is detachably mounted to the rear panel 11 by screws (not shown). Thus, the expansion panel 13 can be freely replaced with a panel of a size suitable for the purpose of use such as the width of the vehicle interior space or stopped.

[0087] The reason why the extension panel 13 is softer than the rear panel 11 and the side panel 12 is as follows. Fig.10 As shown, when the partition member 10 interferes with the vehicle ceiling C due to the lifting of the seat 1, the soft extension panel 13 contacts the vehicle ceiling C and bends, thereby avoiding strong interference with the vehicle ceiling C. Here, the vehicle ceiling C is equivalent to the "vehicle ceiling" of the present invention.

[0088] And, if Fig.11 As shown, when the partition member 10 interferes with the vehicle side wall W (side wall such as the B-pillar) due to the reclining of the seat back 2, the soft extension panel 13 contacts the vehicle side wall W and bends, thereby avoiding strong interference with the vehicle side wall W. Therefore, it is possible to construct the partition member 10 so that it can be in the shape of a panel expanded by the extension panel 13 and appropriately allow interference with the vehicle ceiling C and the vehicle side wall W. Here, the vehicle side wall W is equivalent to the "vehicle side wall" of the present invention.

[0089] like Figure 1-2 As shown, the partition device 4 further includes a blower 20, which includes a blower 21 that blows out wind from the rear to the front along the second concave curved surface 12A of the partition member 10. The blower 20 includes an air duct 22 that is fixed along the first concave curved surface 11A of the partition member 10 and transmits the wind blown out from the blower 21 toward the second concave curved surface 12A.

[0090] Furthermore, the blow-out portion 20 has a rearward-facing air duct 23 fixed to the first concave curved surface 11A of the partition member 10, and transmits the wind blown out from the blower 21 in a manner of blowing out to the rear from the opening 11E provided in the rear panel 11. Furthermore, the blow-out portion 20 has a louver 24, and the louver 24 is attached to the second concave curved surface 12A of the partition member 10, so that the direction of the wind blown out from the blower 21 onto the second concave curved surface 12A is bent to the right.

[0091] The partition device 4 has a pair of left and right speaker units 30, which are mounted on the first concave curved surface 11A of the partition member 10 and can output sound toward the seated person. The partition device 4 also has a pair of left and right speaker units 40 facing backward, which are mounted on the rear surface of the rear panel 11 and can output sound toward the seated person of the rear seat (not shown).

[0092] The partition device 4 includes a display 50 which is mounted on the rear surface of the rear panel 11 and can output an image to a seated person in a rear seat (not shown). The display 50 corresponds to the "accessory" of the present invention.

[0093] (Regarding the Structure of Each Part of the Partitioning Device 4)

[0094] The specific structure of each part of the partition device 4 is described in detail below. Figure 2-Figure 3 as well as Fig. 9 As shown, the blower 20 is fixed to the lower end portion at the center in the seat width direction on the first concave curved surface 11A of the rear panel 11 .

[0095] The blowing part 20 is configured such that the air in the vehicle interior is sucked in from the gap between the rear panel 11 and the seat back 2 with the air inlet of the blower 21 facing downward. Furthermore, the blowing part 20 is configured to blow out the sucked air from the blow outlet opening on the left side of the blower 21. A filter such as a HEPA filter (not shown) is built into the air inlet of the blower 21. The filter adsorbs bacteria and viruses contained in the air sucked in from the air inlet, and blows out the filtered and purified air from the blow outlet.

[0096] Although not shown in the figure, an air conditioning unit is provided in the blow-out unit 20, and the air conditioning unit can adjust the temperature and humidity of the air sucked from the air inlet or add a fragrance component such as aromatic oil to the sucked air. The air conditioning unit can adjust the temperature and humidity set by the seated person operating an electric switch (not shown) and the state of the sucked air in accordance with the setting of the fragrance component to be added to the air.

[0097] The air duct 22 is provided in a shape that one end of the air duct 22 is connected to the outlet of the blower 21 and the air duct 22 extends leftward along the first concave curved surface 11A of the rear panel 11. Specifically, the air duct 22 is formed in a pipe shape having a vertically long U-shaped cross section that is open at the rear.

[0098] The air duct 22 is configured such that the upper and lower tube wall portions are embedded in a concave air duct concave portion 11B formed in the rear panel 11 and is fixed integrally with the rear panel 11 by fastening with screws not shown. By the above fixing, the air duct 22 is configured to form a closed cross-sectional shape that allows wind to flow between the first concave curved surface 11A. Thus, the partition member 10 is reasonably reinforced. The air duct 22 is a shape in which the height dimension of the tube shape gradually becomes longer upward as it extends to the left from the end connected to the blower 21.

[0099] The air duct 22 is in a state where the direction from one end connected to the blower 21 is changed to extend from the left to the front along the first concave curved surface 11A, and the opening of the other end is oriented in the direction along the second concave curved surface 12A. Thus, the air duct 22 can blow the wind blown from the blower 21 from the rear to the front along the second concave curved surface 12A over a wide range in the height direction.

[0100] The rearward air duct 23 is formed in a shape in which one end of the rearward air duct 23 is connected to the blower outlet of the blower 21 and the rearward air duct 23 extends upward along the first concave curved surface 11A of the rear panel 11. Furthermore, the rearward air duct 23 is provided in a state in which the other end of the front end extending upward leads to the rear from the opening 11E formed in the upper center of the rear panel 11 and the rearward air duct 23 opens to the rear from the rear panel 11.

[0101] The rearward air duct 23 is fixed integrally with the rear panel 11 by fastening with screws (not shown). By fixing the rearward air duct 23, the partition member 10 is reinforced appropriately.

[0102] The rearward air duct 23 is formed into a tube shape having a U-shaped cross section that is long and open at the rear. The rearward air duct 23 is configured to be a closed tube shape with a rectangular cross section that allows air to flow between the first concave curved surface 11A and the first concave curved surface 11A by being arranged to touch the first concave curved surface 11A of the rear panel 11 from the front.

[0103] Furthermore, the rearward air duct 23 is a tube-shaped lateral width gradually lengthening to the left and right as it extends upward from one end connected to the blower 21. Thus, the rearward air duct 23 can blow the wind blown from the blower 21 to the rear from the upper portion of the rear panel 11 over a wide range in the seat width direction.

[0104] like Figure 1 , Figure 4 as well as Figure 7 , Fig. 9As shown, the louver 24 is installed in the middle part of the front-back direction on the second concave curved surface 12A of the partition member 10. The louver 24 is composed of a flat plate-shaped member that is long in the height direction. The base end of the louver 24 is hingedly connected to the second concave curved surface 12A in a rotatable manner through a rotating shaft 24A that extends straight in the height direction.

[0105] Thus, the louver 24 is configured to be able to adjust the angle of the surface facing the second concave curved surface 12A to any angle by manual operation of the seated person (user), such as to raise the angle of the surface facing the second concave curved surface 12A to the right or to lay flat to the left along the second concave curved surface 12A. By raising the louver 24 to the right, part of the wind blown from the blower 21 from the rear along the second concave curved surface 12A can be blown onto the louver 24 and bent to the right.

[0106] Thus, the wind direction can be adjusted so that part of the blown wind is blown from the side to the seated person's face or blown to the front of the face. It should be noted that the louver 24 is flat and is thus configured to have a gap between it and the second concave curved surface 12A that forms a three-dimensional concave curved surface. Therefore, regardless of the angle at which the louver 24 is adjusted, part of the wind blown from the blower 21 flows forward on the second concave curved surface 12A through the gap.

[0107] The wind blown forward from the blower 21 along the second concave curved surface 12A spreads over a wide range in the height direction of the second concave curved surface 12A. Figure 6 As shown in the figure, the air curtain can be formed in front of the side panel 12 to blow forward over a wide range in the height direction, and is close to the front side of the head of the seated person in a curved shape that curves to the right of the front portion of the second concave curved surface 12A.

[0108] like Figure 2-Figure 3 , Figure 7-8 As shown, a pair of left and right speaker units 30 are installed in a symmetrical orientation at two positions of the rear panel 11 that are offset from the headrest 3 to the left and right sides. Figure 8 As shown, each speaker unit 30 is provided in a shape covering each speaker recess 11C recessed rearward formed at each corresponding position of the rear panel 11 from the front, and is fixed integrally to the rear panel 11 by fastening with screws (not shown).

[0109] By the above assembly, each speaker recess 11C located at the rear of each speaker unit 30 functions as a housing that surrounds the rear surface of each speaker unit 30 and suppresses sound leakage to the rear. Each speaker unit 30 outputs sound output from an audio device installed in the vehicle.

[0110] like Figure 2-Figure 3 As shown, a pair of left and right speaker units 40 facing rearward are integrally mounted to two left and right positions of the rear panel 11 by fastening with screws (not shown). Specifically, each speaker unit 40 facing rearward is mounted at a position slightly offset inward in the seat width direction from the rear surface of each speaker recess 11C provided with each speaker unit 30 described above.

[0111] Each rearward-facing speaker unit 40 outputs sound output from an audio device installed in the vehicle. In addition, each rearward-facing speaker unit 40 outputs sound produced by a seat occupant of the seat 1 output through a microphone (not shown) provided on the side panel 12 .

[0112] By enabling such sound output, even if the seat 1 and the rear seat (not shown) are separated by the partition 10, the sound produced by the seat occupant of the forward seat 1 can be smoothly transmitted to the seat occupant of the rear seat (not shown).

[0113] The display 50 displays images output from a video device installed in the vehicle. The display 50 is provided from the rear on a flat surface 11D as a mounting seat surface formed in the center of the rear surface of the rear panel 11 and is integrally mounted by fastening with screws (not shown).

[0114] By enabling such image output, even if the forward field of view of the occupant of the rear seat (not shown) is easily blocked by the partition member 10, the image in front of the vehicle captured by the front camera (not shown) mounted on the vehicle can be projected to the occupant of the rear seat (not shown).

[0115] Furthermore, the outer peripheral surfaces of the rear panel 11 and the side panel 12 of the partition member 10 are formed as three-dimensional curved surfaces along the inner peripheral surfaces of the three-dimensional curved surfaces of the rear panel 11 and the side panel 12. Furthermore, reinforcing ribs 14 extending in the seat width direction along the outer peripheral surface are formed at two upper and lower locations on the upper left side of the outer peripheral surface.

[0116] The ribs 14 extend substantially parallel to each other from the side panels 12 to the rear panel 11. Specifically, the ribs 14 have substantially the same length, and the lower rib 14 is disposed to the right of the upper rib 14.

[0117] With the above structure, part of the wind flowing from the front to the rear on the left side (one side) of the partition member 10 is guided to flow behind the rear panel 11 of the partition member 10 due to the wall effect along the outer peripheral surface of the partition member 10. At that time, the wind flowing to the rear is rectified by the rib-shaped reinforcing ribs 14 formed on the outer peripheral surface of the partition member 10 so as to be difficult to spread in the height direction.

[0118] In particular, the wind flowing between the two reinforcing ribs 14 flows backward along the outer peripheral surface of the partition member 10 by being guided from both sides in the height direction by the two reinforcing ribs 14, and does not diffuse greatly in the height direction. Therefore, the wind flowing backward can be appropriately guided behind the rear panel 11 of the partition member 10.

[0119] (Summarize)

[0120] In summary, the partition device 4 of the present embodiment has the following structure. It should be noted that the reference numerals in parentheses below are reference numerals corresponding to the respective structures shown in the above-mentioned embodiment.

[0121] That is, the partition device (4) is provided on the seat (1) and has a partition member (10) on one side (left) to partition the seat from the adjacent seat. The partition member (10) is configured to have a rear panel (11) and a side panel (12) and not cover the seated person from the front, top, bottom and the other side (right), the rear panel (11) being mounted on at least one of the seat back (2) and the headrest (3) of the seat (1) and covering the seated person's head from the rear, and the side panel (12) extending forward from the rear panel (11) through one side (left) and covering the seated person's head from one side (left).

[0122] The rear panel (11) has a first concave curved surface (11A), which is the inner circumference of a three-dimensional curved surface whose upper part and both sides are curved forward and become concave at the front. The side panel (12) has a second concave curved surface (12A), which is the inner circumference of a three-dimensional curved surface whose upper part and front and rear parts are curved toward the other side (right) in a manner that is smoothly continuous with the first concave curved surface (11A) and become concave at the other side (right).

[0123] According to the above structure, by using a partition member (10) composed of a rear panel (11) and a side panel (12) having concave curved surfaces with three-dimensional curved surfaces that are smoothly continuous with each other, a partition that can ensure a comfortable personal space can be formed around the head of the seated person, enclosing the head from the back and one side (left) in a wide and arc-shaped shape.

[0124] Furthermore, the partition device (4) further comprises a blowing unit (20) having a blower (21) for blowing wind from the rear to the front along the second concave curved surface (12A).

[0125] Furthermore, the partition device (4) further comprises an air duct (22) which is fixed in a shape extending from the blowing portion (20) toward the second concave curved surface (12A) along the first concave curved surface (11A) in the seat width direction, and transmits the wind blown out from the blower (21). The air duct (22) itself or between the air duct (22) and the first concave curved surface (11A) forms a closed cross-sectional shape. According to the above structure, the partition member (10) can be reasonably reinforced by the air duct (22).

[0126] In addition, the partition device (4) further comprises a louver (24) which is mounted on the second concave curved surface (12A) so as to bend the direction of the wind blown out from the blower (21) toward the other side (right). According to the above structure, the wind direction can be adjusted so that the wind blown out from the blowing portion (20) blows toward the face of the seated person from the side or toward the front of the face.

[0127] Furthermore, the partition device (4) further comprises a rearward-facing air duct (23) which transmits the wind blown out from the blower (21) in a manner of blowing out to the rear from an opening (11E) provided in the rear panel (11). According to the above structure, the wind can be reasonably blown out to the rear of the partition member (10) by utilizing the blowing portion (20) provided in the partition device (4).

[0128] Furthermore, the partition member (10) further comprises an extension panel (13) which is fixed to the rear panel (11) and extends from at least one of the upper edge of the rear panel (11) and the side edge of the other side (right side) in a manner flush with the rear panel (11). The extension panel (13) is softer than the rear panel (11). According to the above structure, by means of the soft extension panel (13) fixed around the rear panel (11), the shape of the partition member (10) can be extended in a manner that allows interference with surrounding structures such as the vehicle roof (C) and the vehicle side wall (W).

[0129] The partition device (4) further comprises a speaker unit (30) mounted on the first concave curved surface (11A). The rear panel (11) comprises a speaker recess (11C) which is formed by recessing a portion of the first concave curved surface (11A) rearwards in order to form a housing behind the speaker unit (30). According to the above structure, the housing of the speaker unit (30) mounted on the partition member (10) can be reasonably formed by utilizing the structure of the partition member (10).

[0130] Furthermore, the partition device (4) further comprises a speaker unit (40) facing backwards, and the speaker unit (40) facing backwards is mounted on the rear surface of the rear panel (11). According to the above structure, even if the seat (1) and the space behind it are separated by the partition member (10), the speaker unit (40) facing backwards mounted on the rear panel (11) can output sound facing backwards.

[0131] Furthermore, a flat surface (11D) serving as a mounting seat for the accessory (50) is formed on the rear surface of the rear panel (11). According to the above structure, the flat surface (11D) serving as a mounting seat for the accessory (50) can be reasonably formed by utilizing the structure of the rear panel (11) that separates the seat (1) from the space behind it.

[0132] Furthermore, the partition member (10) has a three-dimensional curved outer peripheral surface, the outer peripheral surface of the three-dimensional curved surface is along the inner peripheral surface of the rear panel (11) and the side panel (12), and has a reinforcing rib (14) on the outer peripheral surface, and the reinforcing rib (14) extends in a rib-like manner along the outer peripheral surface in the seat width direction.

[0133] According to the above structure, the wind flowing from the front to the rear on one side of the partition member (10) is guided to flow behind the rear panel (11) of the partition member (10) due to the wall effect along the outer peripheral surface of the partition member (10). At that time, the wind flowing to the rear is rectified in a manner that is difficult to diffuse in the height direction by the rib-shaped reinforcing ribs (14) formed on the outer peripheral surface of the partition member (10). Therefore, the wind flowing to the rear can be appropriately guided to the back of the rear panel (11) of the partition member (10).
