<Vibration body 60>
The vibrating body 60 is a device that applies vibration to a seated occupant. In this embodiment, two vibrating bodies 60 are arranged on the back pad 40. Two vibrating bodies 60 are also arranged on the cushion side (hereinafter, referred to as cushion-side vibrating bodies 61). The back-side vibrating body 60 and the cushion-side vibrating body 61 have the same mechanism.
An eccentric motor is used for the vibrating body 60. Instead of an eccentric motor, a linear vibration actuator or a piezoelectric element may be used for the vibrating body 60. A harness 65 extends from the vibrating body 60 and is connected to an ECU mounted on the vehicle. The ECU can control the strength and timing of vibration of the vibrating body 60.

<Cushion pad 50>
6, the cushion pad 50 is formed with a second horizontal hanging groove 51 extending in the seat width direction and a second vertical hanging groove 52 extending in the front-rear direction.

The second vertical hanging grooves 52 are disposed between the main body 2a of the seat cushion 2 and the bank portions 2b provided on the left and right sides thereof. The second horizontal hanging grooves are provided so as to connect the two second vertical hanging grooves 52 together.

A storage recess 54 for storing the vibration body 61 on the cushion side is formed on the seating surface 50a of the cushion pad 50. The vibration body 61 can be attached by inserting the vibration body 61 into the storage recess 54. As shown in Fig. 8 and Fig. 10A, a harness hole 57 is formed on the bottom surface of the storage recess 54, and by passing a harness 65 extending from the vibration body 61 through the harness hole 57, the harness 65 can be drawn into the bottom surface 50b of the cushion pad 50.
After the vibrating body 61 is inserted into the storage recess 54, a slab 55 is placed on the vibrating body 61 to close the storage recess 44. The slab 55 is fixed with a fixing tape 56. As shown in Fig. 8 and Fig. 10A, a harness hole 57 is formed in the bottom surface of the storage recess 54, and the harness 65 extending from the vibrating body 61 can be passed through the harness hole 57 to lead the harness 65 to the bottom surface 50b of the cushion pad 50.

In the cushion pad 50 shown in FIG. 10A, the harness hole 57 is formed in the bottom surface of the storage recess 54, but the position of the harness hole 57 is not limited to this. As shown in FIG. 10B, as in the storage recess 54' formed in the cushion pad 50', the harness hole 57' may be formed in the side wall and passed through the second lateral hanging groove 51, and the harness hole 57' may be formed leading from the bottom of the second lateral hanging groove 51 to the bottom surface 50b. Also, the harness hole 57' may utilize the hanging hole formed in the second lateral hanging groove 51.

<Positions of Vibrating Bodies 60 and 61>
Hereinafter, the arrangement of the vibrating body 60 of the back pad 40 and the vibrating body 61 of the cushion pad 50 will be described with reference to the drawings.

Conventionally, to notify occupants, a vibrator has been placed on the seat back or seat cushion of a vehicle seat, but sufficient consideration has not been given to placing the vibrator in an appropriate position.

In the vehicle seat S of this embodiment, two vibration bodies 60 that generate vibrations are provided on the back pad 40. As shown in Fig. 3, the two vibration bodies 60 are disposed in positions where at least a portion of each of them does not overlap with the pressure-receiving member 15 when viewed from the front of the vehicle seat S.
Specifically, the two vibrating bodies 60 are disposed at positions on the sides of the plate-like member 152 of the pressure-receiving member 15 and overlapping with the opening 15 c located above the first side portion 153 in a front view.
By arranging the vibration body 60 in this manner, for example, when an occupant sits down or when the vehicle crashes head-on, the occupant sinks into the cushion pad 50, but the vibration body 60 does not hinder the occupant from sinking. That is, when the occupant sinks, the occupant pushes the vibration body 60 rearward, but the pressure-receiving member 15 does not hinder the movement of the vibration body 60, so the occupant's sinking is not hindered. By arranging the vibration body 60 while taking into consideration the position of the pressure-receiving member 15 in this manner, it is possible to provide a vehicle seat S in which the vibration body 60 is arranged in an appropriate position.

As described above, the pressure-receiving member 15 is movable within a movable range R (predetermined range) shown in FIG. 3, but the vibration body 60 is disposed so as to be located outside the movable range R. Therefore, even if the pressure-receiving member 15 moves, the vibration body 60 does not interfere with the pressure-receiving member 15. By arranging them in this manner, it is possible to suppress an increase in discomfort caused by the movement of the pressure-receiving member 15.

As shown in FIG. 5, the vibrating body 60 is disposed at a position overlapping with the pad through-hole 43 formed in the cushion pad 50 in the seat width direction. In other words, the vibrating body 60 is disposed at a position at approximately the same height as the pad through-hole 43 in the seat up-down direction. By disposing it in this manner, the pad through-hole 43 can absorb the deformation of the back pad 40 caused by the vibrating body 60.

5, the vibration body 60 is disposed so as to be located lower than the first horizontal hanging groove 41 extending in the seat width direction. The vibration body 60 is disposed further inward in the seat width direction than the first vertical hanging groove 42 extending in the seat up-down direction. In other words, the vibration body 60 is disposed so as to be sandwiched between the two first vertical hanging grooves 42.
By arranging the vibrating body 60 in this manner, for example, it is possible to suppress the influence of the first horizontal hanging groove 41 and the first vertical hanging groove 42 while suppressing the discomfort felt by the seated occupant.

Furthermore, when the vehicle seat S is provided with a blower 35 and configured to blow air from the seat back 1, a duct 36 may be disposed on the upper part of the seat back 1 as shown in Fig. 5. In such a case, it is preferable that the vibrating body 60 is disposed at a position avoiding the duct 36 provided in the cushion pad 50. By disposing the vibrating body 60 at a position avoiding the duct 36 extending from the blower 35, the effect on the air blown out from the blower 35 can be suppressed.
The vibrating body 60 may be disposed at a position that avoids not only the duct 36 but also the opening of the blower 35 and the blower mounting portion 37 (see FIG. 16A) to which the blower 35 is attached.

<Sensor device 70>
Next, the relationship between the vibrating body 61 and the sensor device 70 will be described. Fig. 11A is a top view showing the seat cushion 2 on which the sensor device 70 is disposed. Note that the seat cushion 2 is shown in a state in which the cover 6 has been removed. As shown in Fig. 11A, the sensor device 70 is disposed in the cushion pad 50 of the seat cushion 2.
The sensor device 70 is a seat belt reminder switch, and is composed of a plurality of sensor units 71 that detect the state of a seat occupant, a connection unit 72 that connects the plurality of sensor units 71 and a harness 65, and a harness 73 that extends from the connection unit 72. The harness 73 is connected to an ECU or the like through a harness hole 74 formed in the cushion pad 50. The sensor unit 71 is a pressure sensor, but may also be a capacitance sensor, and is a biological information detection device that detects biological information of a seat occupant. The sensor device 70 corresponds to a functional component of the present invention.

As shown in FIG. 11A, the vibrating body 61 and the storage recess 54 that stores the vibrating body 61 (hereinafter referred to as the vibrating body 61, etc.) are arranged in a position that avoids the sensor device 70. In other words, the vibrating body 61, etc. are arranged in a position that does not overlap with the sensor device 70 when viewed from above the vehicle seat S. Specifically, the vibrating body 61, etc. are arranged at a predetermined distance from the sensor device 70 in the seat width direction. By arranging the vibrating body 61, etc. in a position that avoids the sensor device 70, it is possible to suppress a decrease in sensor performance.

Moreover, it is preferable that the vibrating body 61 and the like are disposed at a position that avoids the sensor unit 71. By avoiding the sensor unit 71, degradation of the sensor performance can be suppressed.
Moreover, it is preferable that the vibrating body 61 and the like are disposed at a position that avoids the connection portion 72 that connects the sensor portions 71. By disposing the vibrating body 61 and the like at a position that avoids the connection portion 72, it is possible to suppress a decrease in electrical conductivity.
In addition, it is preferable to dispose the vibrating body 61 and the like at a position that avoids the entire sensor including the sensor portion and the connection portion, which can suppress deterioration of the sensor performance and electrical conductivity.

Moreover, the vibrating body 61 and the like may be disposed at a position avoiding the harness hole 74. By disposing the vibrating body 61 at a position avoiding the harness hole 74, the ease of routing the harness 73 is improved.
As described above, the bottom of the storage recess 54 is formed with a harness hole 57 through which the harness 65 of the vibrating body 61 passes, but the harness hole 57 may also serve as a harness hole 74 through which the harness 73 of the sensor passes.
The harness 65 of the vibrating body 61 and the harness 73 of the sensor device 70 that are passed through the bottom side may be bundled together on the bottom side. By bundling them together, the harnesses can be arranged compactly.

The vibrating body 61 and the storage recess 54 may be arranged so as to overlap the sensor device 70, as in the seat cushion 2' shown in FIG. 11B. By arranging them in an overlapping manner, it is possible to arrange multiple components in a compact manner.

In addition, when the cushion pad 50' is composed of a pad main body and an upper pad portion that is combined with the pad main body, it is advisable to place the vibrating body 61 and the sensor device 70 on the upper pad portion before assembling it to the pad main body. Assembling in this manner makes the assembly easier.

In the above description, the vibrating body 61 disposed on the seat cushion 2 is used as an example, but the vibrating body 60 and the storage recess 44 disposed on the seat back 1 should also be disposed in a position that avoids the sensor device 70 disposed on the seat back 1. In other words, when viewed from the front of the vehicle seat S (when viewed from the seating surface), the vibrating body 60, etc. should be disposed in a position that does not overlap with the sensor device 70.

<Heater Device 80>
Next, a description will be given of the relationship between the vibrating body 61 and the heater device 80. Fig. 12 is a top view showing the seat cushion 2A in which the heater device 80 is disposed. Note that the seat cushion 2 is shown in a state in which the cover 6 has been removed.
A heater device 80 is disposed on the cushion pad 50A of the seat cushion 2A.
The heater device 80 is composed of a base fabric 82 and a heater wire portion 81 serving as a heat source disposed on the base fabric 82. The heater device 80 corresponds to a functional component of the present invention.

The vibrating body 61 is preferably disposed at a position overlapping with the heater device 80 in a top view. By disposing them overlapping with each other, it is possible to suppress a decrease in performance of the vibrating body 61 due to low temperatures.
The vibrating body 61 may be disposed at a position overlapping only with the base fabric 82, as in the case of a vibrating body 61Aa shown in Fig. 12. The vibrating body 61 may also be disposed at a position overlapping both with the base fabric 82 and the heater wire portion 81, as in the case of a vibrating body 61Ab shown in Fig. 12. By disposing the vibrating body 61 in this manner, it is possible to suppress the performance degradation of the vibrating body 61 due to low temperatures.

In addition, when the cushion pad 50A is composed of a pad main body and an upper pad portion that is combined with the pad main body, it is advisable to place the vibrating body 61 and the heater device 80 on the upper pad portion before assembling it to the pad main body. Assembling in this manner makes the assembly easier.

13, the vibrating body 61 is fixed by being stored in the storage recess 54, but if it is placed in a position overlapping with the heater device 80, it is advisable to cover it with a lid that has a high insulating effect. By providing a lid 83 that has a high insulating effect, it is possible to suppress a decrease in the temperature rise performance of the heater device 80. In addition, since the base fabric 82 is adhered to the cushion pad 50A, no fixing tape is required.
The harness of the vibrating body 61 and the harness of the heater device (not shown) may be bundled together on the bottom side of the cushion pad. By bundling the harnesses, the harnesses can be arranged compactly.

Furthermore, the vibrating body 61 may be disposed so as to avoid the heater device 80. The vibrating body 61 may be disposed so as to completely avoid the heater device 80, like the vibrating body 61Ac of the seat cushion 2A' shown in Fig. 14. In other words, the vibrating body 61 may be disposed at a position that does not overlap with the heater device 80 in a top view.
The vibrating body 61 may be disposed so as not to overlap a portion of the vibrating body 61Ad with the heater device 80 as shown in FIG.
By arranging the vibrating body 61 so as to avoid the heater device 80, deterioration in the performance of the heater device 80 can be suppressed.

Also, like a vibrating body 60Aa of a seat back 1A shown in FIG. 15, a part of the vibrating body 60 may be disposed at a position overlapping with a base fabric 82 of a heater device 80 disposed in the seat back 1A in a front view.
15, the vibration body 60 may be disposed at a position overlapping the base fabric 82 and the heater wire portion 81. This makes it possible to suppress the performance degradation of the vibration body 60 due to low temperatures.

16, the vibrating body 60 may be disposed so as to avoid the heater device 80. That is, the vibrating body 60 may be disposed at a position not overlapping with the heater device 80 in a front view.
Furthermore, when the heater device 80 is configured in a divided manner, as in the seat back 1A' shown in Figure 16, the vibrating body 60 may be arranged in the gap of the heater device 80, as in the vibrating body 60Ad shown in Figure 16, to avoid the heater device 80.
By arranging the vibrating body 61 so as to avoid the heater device 80, deterioration in the performance of the heater device 80 can be suppressed.

<Air Cell 90>
Next, the relationship between the vibrating body 61 and the air cells 90 provided on the cushion pad 50B will be described. Fig. 17 is a top view showing a seat cushion 2B in which the air cells 90 are arranged. Note that the figure shows a state in which the cover 6 has been removed.

The air cell 90 is a bag that can be inflated by injecting air, and the air cell 90 can inflate to change the shape of the seat or the posture of the seated person. The air cell 90 corresponds to a functional component of the present invention.

The vibrating body 61 is preferably positioned in a position where a portion does not overlap the air cell 90 when viewed from above, i.e., when viewed from the seating surface of the seat cushion 2B, as in the case of vibrating body 61Ba in FIG. 17. Also, as in the case of vibrating body 61Bb in FIG. 17, the vibrating body 61 is preferably positioned in a position where the front portion does not overlap the air cell 90. In other words, the vibrating body 61 is preferably positioned in a position that avoids the air cell 90. By positioning the vibrating body 61 in a position that avoids the air cell, it is possible to suppress deterioration in the performance of the air cell.

18, the vibrating body 61 may be disposed so as to overlap with the air cell 90. By disposing the vibrating body 61 in this manner, it is possible to dispose the vibrating body 61 in a compact manner.
19A, the vibrating body 61 may be disposed above the air cell 90. By disposing the vibrating body 61 above the air cell 90, vibrations are more easily transmitted to the seated occupant.
19B, the vibrating body 61 may be embedded in the storage recess 54 of the cushion pad 2B' and disposed below the air cell 90 of the vibrating body 61Ba. This allows the vibrating body 61 to be disposed in a compact manner.
The distance between the air cells 90 may be changed in accordance with the interval between the vibrating bodies 61 .

Furthermore, when the cushion pad 50B is composed of a pad main body and an upper pad portion that is combined with the pad main body, it is preferable to first place the vibrating body 61 and the air cell 90 on the upper pad portion, and then assemble the upper pad portion to the pad main body. By assembling the upper pad portion in this manner, the assembly can be facilitated.
In addition, the harness 65 of the vibrating body 61 and the harness (not shown) of the air cell 90 may be bundled together on the bottom side of the cushion pad. By bundling the harnesses, the harnesses can be arranged compactly.

20, a part of the vibrating body 60 may be disposed at a position not overlapping with the air cell 90 disposed in the seat back 1B when viewed from the seating surface, i.e., when viewed from the front, as in the vibrating body 60Ba of the seat back 1B. This makes it possible to suppress a decrease in the performance of the air cell 90.
20, the vibrating body 60 may be disposed at a position overlapping with the air cell 90 when viewed from the seating surface, i.e., when viewed from the front, like a vibrating body 60Bb. This allows the vibrating body 60 to be disposed in a compact manner.
In addition, by arranging the air cell 91 of the bank portion mounted on the seat back 1B so as to overlap with the seat width direction, the passenger can easily feel the vibration.

Also, as in the seat back 1B' shown in FIG. 21, a horizontally elongated air cell 92 may be disposed on the back pad 40B. The vibration body 60 is disposed in a position overlapping the air cell 92, as in the vibration bodies 60Bc and 60Bd in FIG. 21. By making the air cell 92 horizontally elongated, it becomes easier to arrange the vibration body 60 so that they overlap.

<Relationship with hanging groove>
The relationship between the vibrating body and the hanging groove will be described with reference to Fig. 22. Fig. 22 is a top view of a cushion pad 50C of a seat cushion 2C, and Fig. 23 is a cross-sectional view taken along line FF in Fig. 22.
22, the vibrating body 61 is preferably disposed at a position overlapping the hanging groove formed in the cushion pad 50C, particularly the second horizontal hanging groove 51, in top view. By disposing it in this manner, it is possible to arrange the vibrating body 61 in a compact manner. The vibrating body 61 may also be disposed at a position overlapping the second vertical hanging groove 52 in top view.
The vibrating body 61 may be disposed at a position that avoids the hanging groove. This makes it possible to suppress a decrease in performance of the vibrating body 61. The vibrating body 61 is preferably disposed at a position that avoids the clip member 67 for fixing the hanging skin 6. This makes it possible to suppress a decrease in performance of the vibrating body.
The vibrator may be disposed near a region sandwiched between a plurality of skin fixing parts (parts where clip members, C-rings, etc. are provided) that fix the skin, which can prevent the skin from becoming loose.
Although the skin may be suspended using a suspending wire, there is a risk that vibrations may not be transmitted. Therefore, it is preferable to use the vibrating body 61 when the skin 6 is fixed with a clip member 67 rather than a suspending wire.

The storage recess 54 for storing the vibrating body 61 is preferably disposed at a position overlapping the hanging groove. The storage recess 54 is preferably disposed at a position overlapping the bottom or side of the hanging groove. This allows the vibrating body 61 to be disposed compactly.
Although the storage recess 54 overlaps with the hanging groove, the vibrating body 61 may be disposed at a position that avoids the hanging groove, thereby preventing the performance of the vibrating body from deteriorating.

<Relationship with variable bank portion 121>
Some vehicle seats have a variable bank portion 121 that can move the bank portion of the cushion pad. The relationship between the vibrating body 61 and the variable bank portion 121 will be described with reference to FIG.
24 is a top view of a seat cushion 2D having a variable bank portion 121 whose position can be changed to the left or right. The seat cushion 2D is configured so that the bank portion can be opened or closed in the left or right direction by a movable mechanism 122. The variable bank portion 121 corresponds to a functional component of the present invention.

24, the vibrating body 61 may be disposed at a position overlapping with the movable mechanism 122 provided inside the variable bank portion 121 when viewed from the seating surface, i.e., when viewed from above, like the vibrating body 61Da shown in FIG. 24. This allows the vibrating body 61 to be disposed in a compact manner.
24, the vibrating body 61 is preferably disposed at a position that avoids the movable mechanism 122. In other words, the vibrating body 61 is preferably disposed at a position that does not overlap with the movable mechanism 122 when viewed from above. By disposing the vibrating body 61 in this manner, the influence on the movable mechanism 122 can be suppressed.

<Relationship with front-rear adjustment mechanism 123>
Some vehicle seats have a front-rear adjustment function that allows the front end of the cushion pad to be extended forward. Fig. 25 is a cross-sectional view that shows a schematic configuration of a seat cushion 2E having a front-rear adjustment mechanism 123 at the front. The front-rear adjustment mechanism 123 can move the front end of the seat cushion 2E as shown by the double-headed arrow A in Fig. 25. The cushion pad 50E is supported by a fixing portion 124. The front-rear adjustment mechanism 123 corresponds to a functional component of the present invention.

As shown in FIG. 25, the vibrating body 61 is disposed behind the movable part of the front-rear adjustment mechanism 123 and the storage recess 125 (the position where the front end of the cushion pad 50E is not extended). The rear of the cushion pad 50 is not moved by the front-rear adjustment mechanism 123, so the vibrating body 61 can be easily installed.

<Relationship with airbags>
Some vehicle seats have an airbag provided on the side. Airbags include side airbags provided on the side of the seatback, and cushion airbags arranged in front of the upper surface of a cushion airbag. Fig. 26 is a front view showing a seatback 1C provided with a side airbag module 100 of the side airbag, and Fig. 27 is a top view showing a seat cushion 2F provided with a cushion airbag module 101. Note that the skin 6 is shown in a removed state. Note that the airbag corresponds to a functional component of the present invention.

A side airbag module 100 for a side airbag is provided on the left side of the seat back 1C, and a tear line (tear portion) is formed on the side of the module. The vibrating body 60 provided on the seat back 1C is disposed in a position that avoids the side airbag module 100, as in the vibrating body 60Ca shown in FIG. 25. It is also disposed in a position that avoids the tear line 102 in the vertical direction. In other words, it is disposed in a position that does not overlap in the seat width direction, i.e., above or below the tear line 102. By arranging the vibrating body 60 in this way, the deployment of the side airbag module 100 is not hindered.

As shown in FIG. 27, a cushion airbag module 101 of a cushion airbag is disposed on the front of the upper surface of the seat cushion 2F. The vibrator 61 provided on the seat cushion 2F is disposed at a position that avoids the bag expansion area 104 of the cushion airbag module 101, as shown in FIG. 27 as the vibrator 61Fa. By disposing it in this manner, the deployment of the cushion airbag module 101 is not hindered.

<Relationship with lighting>
Some vehicle seats are provided with lighting on the side of the seat cushion. Fig. 28 is a top view of a seat cushion 2G provided with a lighting 110. The seat cushion 2G is shown in a state where the cover 6 is removed. The lighting 110 corresponds to a functional component of the present invention.
The vibrating body 61 provided on the seat cushion 2G is disposed near the lighting 110 in the seat width direction, as in the vibrating body 61Ga shown in Fig. 27. That is, the lighting 110 is disposed in front of, to the side of, or above the vibrating body 61Ga. In the drawing, the vibrating body 61Ga is disposed at a position overlapping with the lighting 110 in the seat width direction.
By turning on the light 110 in the vicinity of the vibrating body 61Ga when the vibrating body 61Ga is in operation, it becomes easy to tell that the vibrating body 61Ga is in operation.

<Relationship with pads of different hardness>
Some vehicle seats have back pads and cushion pads made of a plurality of pad materials with different hardnesses.
29 is a top view showing a seat cushion 2H made of padding materials with different hardnesses, with the seat cushion 2H shown in a state where the cover 6 has been removed.
The cushion pad 50H of the seat cushion 2H is formed of a low hardness pad material 111 at its rear side and a high hardness pad material 112 at its front side.

The vibrating body 61 provided in the seat cushion 2H may be provided in the area of the low hardness pad material 111, as in the vibrating body 61Ha shown in Fig. 29. The low hardness pad material 111 has a low density and does not easily transmit vibrations, so that the vibrations can be prevented from being transmitted to other areas.
29, the vibrating body 61 may be provided in the area of the high hardness pad material 112. This makes it possible to transmit vibrations over a wide range.

<Method of arranging the vibrating body 61>
The vibration body 61 described above is disposed in the storage recess 54 of the cushion pad 50 and is positioned parallel to the seating surface 50a, but the arrangement is not limited to this.
Another example of the method of arranging the vibrating bodies will be described with reference to FIGS. 30A to 31B.

<Positional Relationship Between Vibrating Body 61 and Heater Device 80>
FIG. 30A is a schematic diagram of a seat cushion 2I showing the positional relationship between a heater device 80 and a vibrating body 61.
The seat cushion 2I is provided on both sides with side support portions 120, which are bank portions that bulge toward the seated person. A heater wire portion 81 of a heater device 80 is disposed on a seating surface 50a of a cushion pad 50I of the seat cushion 2I.
The vibrating body 61 is disposed, in the seed width direction, outside the side of the heater wire portion 81. That is, the vibrating body 61 is disposed at a position not overlapping with the heater wire portion 81 in a top view.
The vibrating body 61 may be rotated in the direction of arrow A in Fig. 30A and tilted, like the first vibrating body 611 on the right side, or rotated in the direction of arrow B in Fig. 30A and tilted, like the second vibrating body 612 on the left side.
By arranging them in this manner, the vibrating body 61 can be kept away from the heater region (heater wire portion 81), and the influence therebetween can be suppressed.

FIG. 30B is a schematic diagram of a seat cushion 2J showing another example of the positional relationship between the heater device 80 and the vibrating body 61.
30A, the seat cushion 2J is provided on both sides with side support portions 120, which are bank portions bulging toward the seated person. In addition, a heater wire portion 81 of a heater device 80 is disposed on a seating surface 50a of a cushion pad 50J of the seat cushion 2I.
The vibrating body 61 of the seat cushion 2J is disposed, in the seat width direction, inside the side of the heater wire portion 81. That is, the vibrating body 61 is disposed so as to partially overlap with the heater wire portion 81 in a top view.
Even in such a case, the vibrating body 61 may be rotated in the direction of the arrow A in Fig. 30B and tilted, like the first vibrating body 611J on the right side, or rotated in the direction of the arrow B in Fig. 30B and tilted, like the second vibrating body 612J on the left side.
By disposing the vibrating body 61 at an angle, the vibrating body 61 can be separated from the heater region (heater wire portion 81), thereby suppressing the influence of each other.

<Positional Relationship Between Vibrating Body 61 and Sensor Unit>
FIG. 31A is a schematic diagram of a seat cushion 2K showing the positional relationship between a heater device 80, a sensor device 70, and a vibrating body 61.
30A, the seat cushion 2K has side support portions 120, which are banks that bulge toward the seated person, on both sides thereof. A heater wire portion 81 of a heater device 80 and a sensor portion 71 of a sensor device 70 are disposed on both sides of the heater wire portion 81 on the seating surface 50a of a cushion pad 50K of the seat cushion 2K. The sensor device 70 is a biological detection means, and is, for example, a pressure sensor that detects the seating state, etc.
The vibrating body 61 of the seat cushion 2K is disposed, in the seat width direction, outside the side of the sensor portion 71. That is, the vibrating body 61 is disposed at a position where a part of the vibrating body 61 does not overlap with the heater wire portion 81 and the sensor portion 71 in a top view.

Even in such a case, the vibrating body 61 may be rotated in the direction of the arrow A in Fig. 31A and tilted like the first vibrating body 611K on the right side, or rotated in the direction of the arrow B in Fig. 31B and tilted like the second vibrating body 612K on the left side.
By disposing the vibrating body 61 at an angle, the vibrating body 61 can be separated from the sensor area (sensor portion 71), thereby suppressing the influence of each other.

FIG. 31B is a schematic diagram of a seat cushion 2K showing another example of the positional relationship between the heater device 80, the sensor device 70, and the vibrating body 61.
31A, the seat cushion 2L is provided on both sides with side support portions 120, which are bank portions bulging toward the seated person. In addition, the heater wire portion 81 of the heater device 80 and the sensor portions 71 of the sensor device 70 are disposed on both sides of the heater wire portion 81 on the seating surface 50a of the cushion pad 50L of the seat cushion 2L.
The vibrating body 61 of the seat cushion 2L is disposed inward in the seat width direction from the side of the sensor portion 71. That is, the vibrating body 61 is disposed at a position where a part of the vibrating body 61 overlaps with the sensor portion 71 in a top view.

Even in such a case, the vibrating body 61 may be rotated in the direction of the arrow A in Fig. 31B and tilted like the first vibrating body 611L on the right side, or rotated in the direction of the arrow B in Fig. 31B and tilted like the second vibrating body 612L on the left side.
Even if the vibrating body 61 and the sensor section 71 overlap when viewed from above, the vibrating body 61 can be positioned at an angle to move the vibrating body 61 away from the sensor area (sensor section 71), thereby suppressing the influence of each other.

In Figures 30A to 31B, the vibrating body 61 arranged on the seat cushion 2 is described as an example, but the vibrating body 60 arranged on the seat back 1 may be arranged at an angle to be placed away from the heater device 80 and the sensor device 70. This makes it possible to suppress the influence of each other.

The vehicle seat S according to this embodiment has been described above with reference to the drawings. Note that this embodiment is applied to a vehicle seat S mounted on a vehicle, but the seat on which the vibrating bodies 60 and 61 are provided is not limited to the vehicle seat S. It may be an ordinary chair or sofa, and is applicable as long as it has a seating surface. In addition, the arrangement of the vibrating body 60 of the seat back 1 described above may be applied to the vibrating body 61 of the seat cushion 2, and the arrangement of the vibrating body 61 of the seat cushion 2 may be applied to the vibrating body 60 of the seat back 1.
