The seat cushion 11 of this embodiment further includes a seat heater 20 provided between the cushion pad 14 and the skin 15 .

FIG. 3 is a front view showing the seat back with the skin removed. As shown in FIG. 3, the seat back 12 includes a seat back frame (not shown in FIG. 2; see reference numeral 16B in FIG. 8, which will be described later), a cushion pad 14 provided on the seat back frame, and a seat. The outer skin 15 (see FIG. 1) that covers the back frame and the cushion pad 14 is mainly configured.
The seat back 12 of this embodiment further includes a seat heater 20 provided between the cushion pad 14 and the skin 15 .

In the following description, the cushion pad 14 and skin 15 of the seat cushion 11, the seat heater 20 provided on the seat cushion 11, the cushion pad 14 and skin 15 of the seat back 12, and the seat heater provided on the seat back 12 are described. 20 will be described without distinguishing between them.

The seat heater 20 is a planar heating element that heats the seat cushion 11 and the seat back 12. As shown in FIGS. It is mainly composed of a metal heater wire 22 (also referred to as a heating wire) that is adhesively fixed.
1 and the like show the case where the seat heater 20 is provided in the central portion of the seat cushion 11 and the seat back 12, that is, in the seating portions 11A and 12A. may

In this embodiment, the heater wires 22 are adhesively fixed onto the base material 21, and as shown in FIGS. They meander forward and downward, respectively, and are connected at the forward and downward portions. In this case, the heater wire 22 meanders, and its extending direction is the longitudinal direction in the seat cushion 11 and the vertical direction in the seat back 12 .
Note that the arrangement of the heater wires 22 may be changed as appropriate without being limited to the above configuration. Moreover, although the heater wire 22 is fixed on the base material 21 with an adhesive, the heater wire 22 may be fixed so as to be folded inside the base material 21 . Furthermore, the seat heater 20 is not limited to the above configuration as long as it includes the heater wire 22 .

On the other hand, in the present embodiment, as described above, a partial area of the sheet 10 is configured to shine. In this embodiment, a partial area of the outer skin 15 of the seat 10 is particularly illuminated. Hereinafter, this area will be referred to as a shining area α.
As a method for lighting the shining area α of the sheet 10, it is possible to use the methods described in the aforementioned Patent Documents 1 to 6, and the like. It is also possible to use methods other than these.

Specifically, as shown in FIG. 4A, the luminous region α is formed by a phosphorescent body that stores light energy and emits light, a light guide such as an optical fiber, or the like, or by weaving a thin optical fiber. , the luminous area α itself can be made to illuminate in the form of dots, lines, planes, or the like (luminescence). Further, as shown in FIG. 4B, the light emitted from the light source α1 provided on the back side of the glowing region α is transmitted or reflected to form the glowing region α in a dot, linear, or planar shape. It is also possible to make it shine (permeate light) (translucency). β in FIG. 4B will be described later.

In the following description, the method for making the illuminated region α shine is not limited to a specific method unless otherwise specified. For example, it is possible to make the glowing region α shine so that the color, luminous intensity, presence or absence of blinking, etc. do not change with time, or it can be made to shine so that they change with time. be.
In addition, when it is said that light is transmitted, it does not necessarily mean that the shining region α is transparent. In order to prevent the light source α1 from being seen through the glowing region α, the glowing region α is usually configured to scatter or diffuse the light emitted from the light source α1 so as to transmit the light. It is also possible to make the glowing region α transparent so that the light source α1 can be seen.

In the present embodiment, as described above, the luminous or translucent region α of the region of the vehicle seat 10 is provided in the outer skin 15 of the seat 10, and the heater wire of the seat heater 20 is provided. 22 is arranged inside the seat 10 from the upholstery 15 (that is, between the cushion pad 14 of the seat cushion 11 or the seat back 12 and the upholstery 15).
Therefore, since the heater wire 22 of the seat heater 20 is not positioned closer to the occupant than the shining area α provided on the skin 15 of the seat 10, the light in the shining area α is not blocked by the heater wire 22.例文帳に追加

Therefore, according to the arrangement structure of the luminous area α of the seat 10 and the heater wire 22 according to the present embodiment, the passenger or the like can visually recognize the light of the luminous area α of the seat 10 without being blocked by the heater wire 22 . Thus, it is possible to arrange the luminous area α of the sheet 10 and the heater wire 22 in an appropriate positional relationship.
In the configuration shown in FIG. 4B, the light source α1 may be arranged inside the seat 10 (farther from the outer skin 15) than the seat heater 20 and the heater wire 22. However, even in this case, the heater wire 22 is arranged on the inner side of the seat 10 because the glowing region α itself is provided on the outer skin 15 of the seat 10 .

In the following, the arrangement structure of the above-described light-emitting region α of the sheet 10 and the heater wire 22 will be described separately for a first embodiment and a second embodiment, with several specific configuration examples being given for each.
Note that each configuration example below is not limited to the case where it is applied to the members of the seat 10 used in the description (for example, the seat cushion 11, etc.), but the configuration can be applied to other members of the seat 10 (for example, the seat back 12 and the headrest 13). , etc.) where applicable.

Further, even if each of the following configuration examples describes a case in which the shining region α is configured in a point shape, a linear shape, or a planar shape, in the configuration example, the shining region α is configured in another shape including a three-dimensional shape. If possible, it is not limited to the configuration described.
Furthermore, in each of the configuration examples below, even when the shining region α is described as having light-emitting properties (or light-transmitting properties), it can be applied by replacing it with a light-transmitting (or light-emitting) light-emitting region α. is not limited to the case where the shining region α has the described properties (luminescence or translucency). In addition, it goes without saying that appropriate modifications are possible.

[First embodiment]
First, a first embodiment of the present invention will be described. In the present embodiment, the illuminated region α does not overlap the heater wire 22 in the load direction from the passenger seated on the seat 10 (that is, the downward direction for the seat cushion 11, the rearward direction for the seat back 12, and the same below). A description will be given of the case where the position is provided.
In this way, if the shining region α and the heater wire 22 are provided at positions that do not overlap in the load direction, the effect of the heat of the heater wire 22 may cause unevenness in the lighting of the shining region α. It is possible to prevent the heat from the heater wire 22 from becoming difficult to conduct at the portion. This effect is common to each configuration example below.

[Configuration example 1-1]
For example, when the seat 10 has a plurality of portions where the heater wires 22 are arranged (that is, portions where the seat heater 20 is provided), it is possible to provide a glowing region α at a position between each portion. It is possible.
With this configuration, it is possible to realize a configuration (that is, the configuration of the present embodiment) in which the shining region α is provided at a position not overlapping the heater wire 22 in the load direction.

Then, for example, as shown in FIG. 5, when the seat heater 20 and the heater wire 22 are arranged on the seat portion 11A and the bank portion 11B of the seat cushion 11, for example, the shining region α is formed between the seat portion 11A and the bank portion 11B. It is possible to configure so as to be provided at the position of the hanging portion 11C between.
With this configuration, it is possible to provide the shining region α at a position that does not overlap the heater wires 22 in the load direction, and it is possible to improve the design of the seat 10 .

In this case, by utilizing the recess of the suspension portion 11C, for example, as shown in FIG. Let α1. Then, it is possible to arrange a shining region α above it and transmit the light emitted from the light source α1 through the shining region α. 6A, 6B, etc., illustration of the heater wire 22, the cushion pad 14, etc. is omitted.
With this configuration, it is possible to arrange the light source α1 of the shining region α in the concave portion of the hanging portion 11C of the sheet 10, and it is necessary to form a new concave portion in the sheet 10 in order to arrange the light source α1. disappears.

[Configuration example 1-2]
On the other hand, if the shining region α is provided at the position of the hanging portion 11C as described above, there is a possibility that the hanging portion 11C will be adversely affected, such as an increased burden on the hanging portion 11C.
Therefore, for example, as shown in FIG. 6(B), it is possible to configure the shining region α to be provided at a position other than the hanging portion 11C of the sheet 10 .
With this configuration, since the shining region α is not provided at the position of the hanging portion 11C, it is possible to prevent the hanging portion 11C from being adversely affected.

[Configuration example 1-3]
Further, contrary to configuration example 1-1, it is also possible to configure such that a new concave portion is formed in the sheet 10 for arranging the light source α1. That is, as shown in FIG. 4B, for example, it is possible to form a recess β in the cushion pad 14 of the seat 10 and accommodate the light source α1 in the recess β.
With this configuration, the position where the light source α1 is arranged is not limited to the hanging portion 11C of the seat 10 as in the configuration example 1-1, but any position such as the seat cushion 11 or the cushion pad 14 of the seat back 12. It is possible to form a recess β in the , and dispose the light source α1. Therefore, it becomes possible to provide a shining region α at an arbitrary position on the skin 15 such as the seat cushion 11 or the seat back 12, and to form the shining region α in an arbitrary shape such as a dot shape, a linear shape, a planar shape, or the like. becomes possible.

[Configuration example 1-4]
Also, it is possible to provide the shining region α in the movable portion of the sheet 10 .
Here, the movable portion of the seat 10 includes the entire seat cushion 11, the entire seat back 12, bank portions 11B and 12B thereof, a headrest 13, a neck rest 17 (see FIG. 15 and the like to be described later), an armrest 18 (to be described later). 27), a footrest (not shown), an ottoman (not shown), and the like.
By providing the illuminated area α in the movable portion of the seat 10, the design of the seat 10 can be improved.

Further, when moving the movable portion such as when the seat back 12 (see FIG. 4A) is tilted backward, for example, before starting the movement, the glowing region α is lit (preferably blinking), and then It is configured to notify the occupants around the seat 10 that the movable part starts to move to call their attention, and to notify the occupants around the occupants that the movable part is moving by lighting the region α that shines even during the movement. It is possible.
With this configuration, it is possible to call attention to the movement of the movable portion of the seat 10 from the surrounding occupants, and the surrounding occupants do not notice the movement of the movable portion of the seat 10 and collide with the movable portion. It is possible to accurately prevent the occurrence of accidents such as injuries due to accidents.

In the above case, for example, a shining area α is also provided on the back side of the seat back 12, and the shining area α on the back side of the seat back 12 is illuminated or blinked as the seat back 12 moves. It is also possible to configure such that the color of the light is changed.
With this configuration, it is possible to make the occupant seated on the seat 10 behind the seat 10 accurately recognize that the seat 10 moves.

[Configuration example 1-5]
Further, in contrast to configuration example 1-4, it is possible to configure such that the shining region α is not provided in the movable portion of the sheet 10 . That is, it is also possible to configure so that the illuminated area α is provided at a position other than the movable portion of the sheet 10 .
If the shining region α is provided in the movable portion of the sheet 10, the shining region α may come into contact with another member and rub against another member, or the wiring may be damaged due to the movement of the movable portion provided with the shining region α. However, with the configuration described above, such problems do not occur.

[Configuration example 1-6]
In the case where a plurality of portions of the seat 10 are provided with a light area α such as the seat cushion 11 and the seat back 12 of the seat 10, for example, as shown in FIG. 10 seat cushions 11 and seat backs 12) can be configured to have their own independent light sources α1.
In this case, for example, when the light source α1 in the glowing region α is configured to have a light emitting part α2, a light guide body α3, a control part α4 for controlling the light emitting part α2, and the like, the light emitting part α2 and the guide body are provided on the seat cushion 11, for example. A light source α1 including a light body α3, a control part α4, etc. is provided, and the seatback 12 is configured to be provided with a light emitting part α2, a light guide body α3, a control part α4, etc. as another light source α1.

With this configuration, it is possible to illuminate the illuminated regions α respectively provided in a plurality of portions of the seat 10 (for example, the seat cushion 11 and the seat back 12) by the independent light sources α1. It is possible to improve the degree of freedom of the arrangement position of the light guide α3 and the routing of the light guide α3.

[Configuration example 1-7]
Further, in contrast to the configuration example 1-7, when the light-emitting area α is provided in each of a plurality of portions of the sheet 10, the light source α1 of the light-emitting region α of each portion can be shared.
That is, for example, as shown in FIG. 7B, each portion of the seat 10 (for example, the seat cushion 11 and the seat back 12 of the seat 10) has a glowing region α, which has one light emitting part α2 and one control part α4. It is also possible to configure so that it is illuminated by one light source α1.

With this configuration, it is possible to control how the lighted areas α of the respective parts of the sheet 10 are lit by the control part α4 of the single light source α1, and the lighted areas α of the respective parts of the sheet 10 are interlocked. It is possible to appropriately and easily construct a lighting control configuration with one control unit α4.
In addition, when the seat cushion 11 is included in a plurality of portions of the seat 10 provided with the illuminated area α as described above, the seat cushion 11 may be significantly rocked in the front-rear direction. Since the movement of the light source α1 is small, providing the light emitting part α2, the control part α4, etc. of the light source α1 on the seat cushion 11 side reduces the possibility that the movement of the seat 10 will cause the light source α1 to malfunction. Therefore, when the seat cushion 11 is included in a plurality of portions of the seat 10 in the configuration as in Configuration Example 1-7, it is preferable to provide the light source α1 on the seat cushion 11 side.

[Configuration example 1-8]
By the way, in this embodiment, the seat 10 incorporates a seat frame 16 as shown in FIG. The seat frame 16 has a cushion frame 16A forming the seat cushion 11 and a seatback frame 16B forming the seatback 12. As shown in FIG.
The seat 10 is formed by arranging the above-described cushion pads 14 on the cushion frame 16A and the seat back frame 16B, respectively, and covering them with the skin 15. As shown in FIG.

The seat frame 16 (cushion frame 16A, seat back frame 16B) is provided with a pair of left and right side frames 16C.
The cushion frame 16A includes a plate-like pan frame 16D connecting the front ends of the pair of side frames 16C together, and a connecting pipe 16E connecting the rear ends of the pair of side frames 16C. A seat spring 16F is installed as a pressure receiving member between the pan frame 16D and the connecting pipe 16E.

In this case, if the light source .alpha.1 of the luminous area .alpha. In this case, the light source α1 may be sandwiched between the cushion pad 14 and the pressure receiving member, receive strong pressure, and may be damaged.
Therefore, the light source α1 of the illuminated region α is preferably provided at a position other than the position between the cushion pad 14 and the pressure receiving member (seat spring 16F).

For example, the light source α1 is placed between the side frame 16C of the cushion frame 16A (see FIG. 8) and the pressure-receiving member (that is, in the example of FIG. 8, on the left and right sides of the seat spring 16F and inside the side frame 16C). It can be configured to provide
Thus, by providing the light source α1 of the illuminated region α at a position other than the position between the cushion pad 14 and the pressure receiving member, such as between the side frame 16C and the pressure receiving member, the occupant can When the seat cushion 11 is seated on the seat cushion 11, the light source α1 is sandwiched between the cushion pad 14 and the pressure-receiving member and is damaged.

[Configuration example 1-9]
On the other hand, as a place for arranging the light source α1 of the glowing region α, for example, as shown in FIG. be. At that time, the light source α1 is arranged so as to emit light in the direction toward the passenger A seated on the seat 10 .
With this configuration, it is possible to stabilize the arrangement of the light source α1 by attaching the light source α1 to the side frame 16C. At the same time, wiring and the like (not shown) for supplying power to the light source α1 can be arranged so as to pass through the inside of the side frame 16C or along the side frame 16C. There is no need to newly provide holes, recesses, or the like in the cushion pad 14 for this purpose.

FIG. 9 shows a case where the light source α1 of the illuminated region α is attached above the side frame 16C of the cushion frame 16A or in front of the side frame 16C of the seatback frame 16B. (Refer to the light source α1A on the left side in the figure), it is also possible to configure so as to be attached inside the side frame 16C of the seat frame 16 (cushion frame 16A, seat back frame 16B).
With this configuration, even if an impact or the like is applied from the outside of the seat 10, the side frames 16C can protect the light source α1 from the impact or the like. In this case, if the cushion pad 14 or the like is assembled, it becomes difficult to confirm whether or not the light source α1A is attached. It is also possible to provide a confirmation opening 16H.

[Configuration example 1-10]
Further, in contrast to the configuration example 1-9, the light source α1 of the shining region α is set to the seat frame 16 (cushion frame 16A, seat back frame 16B) as shown in FIG. It is also possible to configure it so as to be attached to the outside of the side frame 16C.

There may be cases.
Therefore, it is possible to configure so that the illuminated region α is provided in a portion of the outer skin 15 other than the portion corresponding to the ventilation path 30 for air conditioning. With this configuration, it is possible to prevent the above problems from occurring.

[Configuration example 1-12]
Further, contrary to configuration example 1-9, it is also possible to configure so that the shining region α is provided in the portion of the skin 15 corresponding to the ventilation path 30 for air conditioning.
In this case, for example, as shown in FIG. 12, by arranging the light source α1 of the glowing region α in the concave portion 20D provided in the ventilation path 30, the air in the ventilation path 30 is It is configured so that it does not affect the flow of water (or, if it does, the effect is minimized as much as possible).

With this configuration, for example, as shown in FIG. 12, it is possible to transmit the light from the light source α1 to the outside from the air blowing port 30C using the air blowing port 30C of the air passage 30, corresponding to the air blowing port 30C. It becomes possible to provide a shining region α in the portion of the epidermis 15 where the light is applied.
In addition, it is also possible to form a structure as shown in FIG. 12 in a portion other than the blower port 30C and provide a shining region α in that portion. Then, in that case, it is possible to provide the portion transmitting the light from the light source α1, that is, the shining area α in a dot shape such as the air blowing port 30C, or in a linear shape along the ventilation path 30. It is possible.

[Configuration example 1-13]
By the way, the seat 10 has a biosensor 32 on the seat 10 as a detection means for detecting the state (health state, awake state, etc.) of the seated occupant A (especially the driver), for example, as shown in FIG. may be provided. The biosensor 32 is of a non-contact type, and detects biometric information such as the blood flow state of the occupant A by emitting electromagnetic waves to the occupant A, for example.
Then, the information obtained by the biosensor 32 is analyzed by an external analysis device or the like, and the state of the seated occupant A is grasped. The electromagnetic wave in this case means a wide range of electromagnetic waves including radio waves and microwaves of about 100 MHz, infrared light, visible light, ultraviolet light, X-rays, etc., and does not adversely affect the human body. electromagnetic waves are used.

As shown in FIG.

In the case where the sheet 10 is provided with a detection means such as the biosensor 32 in this way, for example, if a glowing region α is provided in the portion of the skin 15 within the irradiation range R of the electromagnetic waves emitted from the biosensor 32, When interference occurs between the glowing region α and the biosensor 32, such as when the glowing region α interferes with the transmission of electromagnetic waves, and the electromagnetic waves are affected, which may affect the detection results of the biosensor 32. There is
Therefore, if the seat 10 is provided with detection means such as the biosensor 32 for detecting the state of the seated occupant A, as shown in FIG. It is possible to configure such that it is provided at a position that does not interfere with the transmission of electromagnetic waves emitted from the sensor 32 . With this configuration, it is possible to prevent the above problems from occurring.

[Configuration example 1-14]
On the other hand, for example, even if a shining region α is provided in the portion of the epidermis 15 within the irradiation range R of the electromagnetic wave emitted from the biosensor 32, the electromagnetic wave emitted from the biosensor 32 is not affected. Even if it is provided at a position overlapping the detection means such as 32 (that is, at a position overlapping in the direction of the load from the passenger A seated on the seat 10), the detection operation of the detection means may not be affected in some cases.
In such a case, as shown in FIG. 14, it is possible to provide a shining region α at a position overlapping the detection means in the direction of the load from the occupant A seated on the seat 10 . It should be noted that it is also possible to provide the glowing region α at the above-described position as well as at a position away from the detection means.

With this configuration, it is possible to provide the glowing area α at any position regardless of the position where the detecting means is arranged, and at least the glowing area α can be freely provided without limitation with respect to the detecting means. becomes.
Also, although illustration is omitted, in this case, it is possible to arrange the light source α1 of the glowing region α in the vicinity of the detection means such as the biosensor 32. It is possible to dispose the detection means and the light source α1 at the same position, so that they can be arranged compactly.

[Configuration example 1-15]
In some cases, the seat 10 is provided with a neck rest. When the seat heater 20 having the heater wire 22 is arranged on the neck rest, the seat heater 20 and the heater wire 22 are usually attached to the neck rest as shown in FIG. It is arranged in the central part of the plate 17 .
Therefore, in the present embodiment, in which the area α that shines in the direction of the load from the occupant A seated on the seat 10 is provided at a position that does not overlap the heater wire 22, as shown in FIG. It is provided at a position other than Although FIG. 15 shows a case in which the luminous regions α are provided at both left and right ends of the neck rest 17, the present invention is not limited to this. may be provided.

With this configuration, the heater wire 22 of the seat heater 20 is not located closer to the occupant A than the illuminated area α of the neck rest 17, so that the heater wire 22 does not block the light in the illuminated area α. Therefore, the occupant A or the like can visually recognize the light of the illuminated area α of the neck rest 17 without being blocked by the heater wire 22 .

[Second embodiment]
Next, a second embodiment of the invention will be described. In this embodiment, the illuminated region α overlaps the heater wire 22 in the direction of the load from the passenger A seated on the seat 10 (that is, the downward direction for the seat cushion 11, the rearward direction for the seat back 12, and the same below). A description will be given of the case where the position is provided.
In this way, if the lighting area α and the heater wire 22 are provided at overlapping positions in the load direction, in the seat 10, the lighting area α and the heater wire 22 (seat heater 20) are collectively provided in a compact manner. There is an effect that it becomes possible to This effect is common to each configuration example below.

As the material of the luminous area α, a material that does not cause unevenness in the luminescence caused by the heat of the heater wire 22 may be used. It is also possible to configure the sheet 10 so that the color of the light changes depending on the temperature, and to positively utilize such properties in the design of the sheet 10 .
In addition, when the light area α does not affect the ease of heat transfer of the heater wire 22 (or even if it does affect it, it does not matter in practice), and the light area α is not affected by the heat of the heater wire 22 either. , it is possible to provide the shining region α at an arbitrary position on the sheet 10 without worrying about the arrangement of the heater wires 22 on the sheet 10 .

[Configuration example 2-1]
When the heater wire 22 is arranged to straddle a plurality of parts of the seat 10, the shining region α is provided at a position overlapping the heater wire 22 in the load direction from the occupant A seated on the seat 10. - 特許庁It is possible.
Specifically, for example, as shown in FIG. 16, when the heater wire 22 is arranged so as to include the seating portion 11A and the bank portion 11B of the seat cushion 11 of the seat 10, the illuminated area α is the seating portion 11A. and the bank portion 11B.

With this configuration, it is possible to realize a configuration in which the shining region α is provided at a position overlapping the heater wires 22 in the load direction, and it is possible to improve the design of the seat 10 .
Further, if the lighting area α is provided in the hanging portion 11C between the seating portion 11A and the bank portion 11B, it is possible to arrange the light source α1 of the lighting area α in the concave portion of the hanging portion 11C of the seat 10. Therefore, it is not necessary to form a new concave portion in the sheet 10 for arranging the light source α1.

Also in this case, as described in the configuration example 1-2 described above, if the shining region α is provided at the position of the hanging portion 11C, the load on the hanging portion 11C increases. If there is a possibility of adverse effects, for example, as shown in FIG. 6B, it is also possible to provide the shining region α at a position other than the hanging portion 11C of the sheet 10 .

[Configuration example 2-2]
In the example of the heater wire 22 shown in FIGS. 2 and 3, the heater wire 22 meanders. 3), it is in the vertical direction.
Then, for the heater wire 22 extending in this way, for example, as shown in FIG. 17, a shining region α is provided so as to intersect the extending direction of the heater wire 22 in the load direction. is possible.

With this configuration, even if the luminous region α does not affect the ease of heat conduction of the heater wire 22, and even if it is formed of a material that affects the easiness of heat transfer, the luminous region Since it is possible to reduce the area where α intersects the heater wire 22, it is possible to minimize the influence of the glowing region α on the ease of heat conduction of the heater wire 22.

[Configuration example 2-3]
Further, contrary to configuration example 2-2, for example, as shown in FIG. 18, it is also possible to configure so that the shining region α is provided parallel to the extending direction of the heater wire 22 in the load direction.
With this configuration, the occupant A (not shown) seated on the seat 10 feels as if heat is emitted from the luminous area α, and the effect of soothing the occupant A during the harsh winter, for example, can be obtained. becomes possible.

[Configuration example 2-4]
On the other hand, similarly to the configuration example 1-4 and the configuration example 1-5, it is possible to provide the light area α in the movable portion of the sheet 10, or to provide it in a position other than the movable portion of the sheet 10. It is also possible to configure
Then, it is possible to obtain the same effects as in the configuration example 1-4 and the configuration example 1-5.

[Configuration example 2-5]
In addition, depending on the state of the seat heater 20 including the heater wire 22 arranged at a position overlapping the glowing region α in the load direction, the glowing region α itself emits light or is irradiated from the light source α1. It is possible to configure such that the color and luminosity of the light are changed when the light is transmitted through the luminous area α.
It is also possible to configure the glowing region α so that the color and luminous intensity of the light emitted or transmitted changes according to the temperature of the seat heater 20 .

In this case, for example, the control unit α4 (see, for example, FIGS. 7A and 7B) of the light source α1 in the glowing region α controls the energization state of the heater wire 22, etc., and the control unit (not shown) of the seat heater 20 , obtain information from a temperature sensor (not shown) that measures the temperature of the heater wire 22, the skin 15 of the seat 10, etc., and control the color and luminous intensity of the light emitted from the light emitting part α2 of the light source α1. .

Specifically, for example, when the heater wire 22 is not energized or the temperature of the seat heater 20 is low, the light source α1 is extinguished so that the luminous area α is not illuminated, or the luminous intensity is reduced, or the light intensity is reduced. It is possible to change the color of to a cold color such as light blue or blue.
Further, for example, when the heater wire 22 is energized or the temperature of the seat heater 20 is high, the luminous intensity of the light emitted from the light source α1 is increased to make the luminous area α high, or the color of the light is increased. can be set to a warm color such as yellow or orange.
Further, for example, for a predetermined time after the start of energization of the heater wire 22, the glowing area α is flashed to inform the occupant A that energization has started, or the glowing area α during rapid heating. can be configured to emit light in orange, red, or the like, or transmit light.

With this configuration, the color and luminosity (including extinguished, blinking, etc.) of the light in the illuminated region α change depending on the state and temperature of the seat heater 20, so that the design of the seat 10 can be improved. . Also, the state and temperature of the seat heater 20 can be easily and accurately recognized by the occupant A by visually recognizing the color and luminous intensity of the light in the illuminated area α. .

[Configuration example 2-6]
Incidentally, although FIGS. 16 to 18 illustrate the case where the shining region α is provided in a linear shape, it goes without saying that the shining region α can also be provided in a dot shape or a planar shape.
When the shining area α is provided in a planar shape, it can be provided so as to overlap the portion where the seat heater 20 having the heater wire 22 is arranged in the direction of the load from the occupant A seated on the seat 10.

In this case, the illuminated region α may be provided so as to be included in the range in which the seat heater 20 is arranged as shown in FIG. 19 in the load direction, and the seat heater 20 is arranged as shown in FIG. 21, or may be provided so as to include the range where the seat heater 20 is arranged as shown in FIG.
Further, in the case where the shining area α is provided so as to be included in the range in which the seat heater 20 is arranged in the load direction, as shown in FIG. It is also possible to configure

With this configuration, it is possible to make the occupant A seated on the seat 10 feel that the light and heat are transmitted from the illuminated area α.
Note that when the illuminated area α is planar, it is not necessary to have a rectangular shape as shown in FIGS. 19 to 21, and other shapes may be used.

[Configuration example 2-7]
Further, in the case where the seat cushion 11 of the seat 10 and the cushion pad 14 such as the seat back 12 are provided with an air-conditioning air passage 30 for passing air (warm air or cold air), the configuration example 1-12 described above is used. As in the case of (1), it is possible to provide the illuminated region α at a position overlapping the air-conditioning air passage 30 (see FIG. 11) in the direction of the load from the occupant A seated on the seat 10 .
Then, as shown in FIG. 12, the shining region α is provided at a position overlapping with the air outlet 30C of the air conditioning ventilation passage 30 toward the occupant, or the light source α1 of the shining region α is provided in the air conditioning ventilation passage 30. It is possible to configure so as to be provided in

When the light source α1 is provided in the ventilation passage 30 for air conditioning, as described above, the provision of the light source α1 should not affect the air flow in the ventilation passage 30 (or should the air flow in the ventilation passage 30 be affected). is configured so that its influence is as small as possible).
With the above configuration, for example, as shown in FIG. 12, the illuminated region α is provided along the ventilation path 30, or the air outlet 30C of the ventilation path 30 is used to project the light source outward from the air outlet 30C. It becomes possible to transmit the light from α1, and the design of the sheet 10 can be improved.

[Configuration example 2-8]
Further, in the configuration example 1-15 described above (see FIG. 15), when the illuminated area α is provided in the neck rest 17 of the seat 10, it does not overlap with the seat heater 20 or the heater wire 22 arranged in the central portion of the neck rest 17. Thus, the case where the shining region α is provided at a position other than the central portion of the neck rest 17 has been described.

However, in the present embodiment in which the shining region α is provided at a position overlapping with the heater wire 22, as shown in FIG. can be provided at a position overlapping with the heater wire 22 or the like.
With this configuration, the occupant A, who leans his neck against the neck rest 17, feels as if his neck is warmed by the heat emitted from the glowing area α, and effects such as healing the occupant A can be obtained. becomes possible.

[Other configurations, etc. related to the glowing area]
In the following, other configurations and the like related to the illuminated area α in the sheet 10 will be described by citing several configuration examples.
It should be noted that each of the following configuration examples may be configured in combination with the above-described first embodiment and second embodiment.

[Configuration example 3-1]
When the seat 10 is provided with the illuminated area α, the illuminated area α of the seat 10 may be visible from the outside of the vehicle through a window such as a door.
Therefore, for example, as shown in FIG. 23, it is possible to configure the illuminated area α of the seat 10 to light up (including flashing, etc.; the same shall apply hereinafter) when the occupant A approaches the vehicle 100 from outside the vehicle. be.

In this case, as shown in FIG. 23, if the illuminated area α is provided on the seat 10 on the side of the door 101 of the vehicle 100, the occupant A approaching the vehicle 100 from outside the vehicle 100 can see the illuminated area of the seat 10. It becomes possible to visually recognize α more reliably.
With this configuration, when the occupant A approaching the vehicle 100 from outside the vehicle sees that the illuminated area α of the seat 10 is illuminated, the approach of the occupant A is detected by the vehicle 100 (e.g., the ECU of the vehicle 100. The same applies hereinafter). ) can be easily confirmed.

In this case, for example, a passenger A carrying an electronic key (wireless key, keyless entry key, smart entry key, etc.) approaches from outside the vehicle, or the passenger A operates a button on the electronic key outside the vehicle. Alternatively, the vehicle 100 detects that the key has been inserted into the keyhole (not shown) of the door 101 to unlock it, or that the doorknob 102 has been operated. A), (B)) can be obtained and configured to illuminate the glowing region α.

[Configuration example 3-2]
In order to notify the occupant A when the state of the occupant A seated on the seat 10 (sleepiness, poor physical condition, etc.), the traveling direction of the vehicle (right or left turn direction), the approach of another vehicle, etc. In some cases, a vibrating body is provided, and the occupant A is notified by vibrating the vibrating body and vibrating a portion of the seat 10 .

In such a case, for example, as shown in FIG. 24, a vibrating body 34 provided on the seat cushion 11 or the seat back 12 of the seat 10 and an area α illuminated at a position where the load from the occupant A seated on the seat 10 overlaps. can be configured to provide
With this configuration, it is possible to notify the occupant A not only by the vibration of the vibrating body 34 but also by the light emission of the luminous area α, so that the occupant A can be notified more accurately.

Further, with the configuration as described above, for example, when the occupant A who is seated on the seat 10 is in poor physical condition and faints and does not wake up even if the vibrating body 34 is vibrated, the vibrating body 34 will not wake up. The area α that not only vibrates but also glows emits light. Therefore, other occupants near the occupant A notice that the illuminated area α of the seat 10 on which the occupant A is seated emits light, and the fact that the occupant A faints or the like is accurately detected. can be discovered.

[Modification 1 of Configuration Example 3-2]
In this case, if the vibrating body 34 and the luminous area α are provided in the seating portions 11A and 12A of the seat cushion 11 and the seat back 12, the luminescence of the luminous area α is hidden by the body of the occupant A and other occupants do not see it. Other occupants may not notice that the glowing region α is emitting light because it cannot be visually recognized.
Therefore, in the above case, as shown in FIG. 24, it is desirable to provide the shining regions α in the bank portions 11B and 12B of the seat cushion 11 and the seat back 12 . With this configuration, the light emission of the luminous area α is not hidden by the body of the occupant A, so that other occupants can accurately visually recognize that the luminous area α is emitting light.

[Modification 2 of Configuration Example 3-2]
Further, in the above case, if the vibrating body 34 and the luminous area α are provided on the bank portion 11B of the seat cushion 11, the seat cushion 11 is at a low position. There may be a case where one does not notice that the region α that shines at 1 is emitting light.
Therefore, in the above case, as shown in FIG. 24, it is desirable to provide the shining region α in the bank portion 12B of the seat back 12. As shown in FIG. With this configuration, the glowing area α emits light at a position close to the eye level of the other occupants, so that the other occupants can reliably recognize that the glowing area α is emitting light. .

[Modification 3 of Configuration Example 3-2]
In addition, in the above configuration, it is possible to configure the luminous region α to emit light with uniform luminous intensity as a whole. It is also possible to emit light so that the light emission position α ^* in the light region α moves from the position of the vibrating body 34 to another position in time.

In this case, for example, when the vibrating body 34 or the luminous area α is provided on the seat cushion 11, the light emitting position α ^* of the luminous area α moves in the front-rear direction or the left-right direction (or other direction) of the seat cushion 11. For example, when the vibrating body 34 and the light-emitting region α are provided in the seat back 12, the light-emitting position α ^* of the light-emitting region α is set in the vertical direction or the horizontal direction (or other directions).
With this configuration, it is possible to visually recognize light as if it were flowing within the glowing region α, so that visibility and design can be improved.

[Modification 4 of Configuration Example 3-2]
It should be noted that the vibrating body 34 and the glowing region α may be provided at a position overlapping the heater wire 22 in the load direction from the occupant A seated on the seat 10 . Also, if the vibrating body 34 or the glowing area α is provided at a position overlapping the heater wire 22, the heat of the heater wire 22 is difficult to be transmitted in that part. It may be configured to be provided at a position other than the position where it is located.

Further, as in the above configuration example 3-2 (see FIG. 24), if the shining area α is provided at a position overlapping the vibrating body 34 in the direction of the load from the occupant A seated on the seat 10, the vibrating body 34 If the vibration is less likely to be transmitted to the occupant A, it is also possible to provide the glowing region α at a position other than the position where the vibrating body 34 is provided in the load direction.
Furthermore, it is also possible to arrange the vibrating body 34 so as to overlap the position where the heater wire 22 is arranged, and to provide the shining region α at a position that does not overlap with them.
Further, it is also possible to arrange the shining area α, the vibrating body 34 and the heater wire 22 so that none of them overlap in the direction of the load from the occupant A seated on the seat 10 .

[Configuration example 3-3]
On the other hand, currently, technology for detecting roads and pedestrians in front of the vehicle based on images taken by the vehicle (vehicle ECU, etc.; the same shall apply hereinafter) taken in front of the vehicle for the purpose of automatic driving and driving support for the driver. is being developed. In some cases, the signal color (red, yellow, and green) of the traffic light in front of the vehicle can also be detected.
In addition, development of a vehicle communication system that exchanges various information by communicating between vehicles and between vehicles and base stations installed along the road is currently underway. There is also a possibility that it will become possible to obtain information on the signal color of traffic lights from other vehicles, base stations, and the like.

Therefore, if the vehicle is configured to detect the signal color of the traffic signal in front or obtain information on the signal color of the traffic signal in front from another vehicle or a base station, the detection result Alternatively, the obtained information can be obtained by the controller α4 of the lighting area α, and based on this, the lighting area α of the sheet 10 can be configured to emit light in the same color as the signal color of the traffic light.
That is, for example, as shown in FIG. 26, the front portion of the seat 10 of the driver's seat (for example, the front end portion of the seating portion 11A of the seat cushion 11, the bank portion 11B, the front outer end portion of the bank portion 11B, etc.) is provided with a shining region α. The glowing area α is made to emit light in the same color as the signal color of the traffic light.

With this configuration, if the driver looks down for some reason and sees the color of the light in the illuminated area α, the current color of the traffic light in front of the vehicle or the color of the traffic light changes from red to blue. It becomes possible to recognize whether or not it has changed to
This makes it possible for drivers who are looking down to recognize the signal color without looking up, and also solves the problem of noticing that the signal color has changed because the driver was looking down. It is possible to accurately prevent such occurrence.

Incidentally, if a luminous area α is provided on the side or back side of the seat 10 of the driver's seat or on the other seat 10, the occupant A other than the driver can recognize the signal color of the traffic light and its change. This makes it possible to improve the recognition of the signal color of the traffic light, its change, etc. throughout the vehicle.

[Configuration example 3-4]
Further, it would be convenient if the light emission form (light color, luminosity, shape, etc.) of the glowing region .alpha.
Therefore, for example, the seat 10, the armrest 18 (see FIG. 27), or the like is provided with a selection means 36 such as a switch or a touch panel that can be operated by the occupant A to select the light emission form of the glowing area α. It is configurable. Then, the controller α4 for the glowing region α causes the glowing region α to emit light in the selected light emission form.

With this configuration, the occupant A operates the selection means 36 to select and change the light emission form of the area α according to his or her preference (for example, change the light color to a warm color). becomes possible.
Further, in the configuration as described above, if the selection means 36 is provided on the armrest 18, particularly on the upper surface of the armrest 18, as shown in FIG.

In addition to changing the luminous form of the luminous area α according to the preference of the occupant A as described above, for example, when the physical condition of the occupant A suddenly changes, the luminous area can be used to notify the other occupants of the change. It can also be used to change the emission form of α.
Furthermore, the state of the passenger A (physical condition, arousal state, etc.) is detected by a detecting means such as the biosensor 32 (see FIG. 13), etc., and the control unit α4 of the glowing area α detects the state of the passenger A. It is also possible to configure such that the luminous form of the luminous area α is automatically changed accordingly.

[Configuration example 3-5]
In addition, the control unit α4 of the glowing area α obtains vehicle information (for example, the remaining amount of fuel, etc.) and information on the driving state (driving duration, travel distance, etc.) from the vehicle ECU, etc., and lights the area α accordingly. It is also possible to configure such that the luminous form of is automatically changed.
With this configuration, the occupant A can recognize the vehicle information and the driving state by looking at the light emission form of the light area α.

[Configuration example 3-6]
Incidentally, when the occupant A, seated on the seat 10, operates the inner handle (not shown) of the door 101 of the vehicle 100 (see, for example, FIG. 23) to open the door 101 in order to get off the vehicle, the door 101 is opened. In the case where the inside of the door 101 (the side on which the inner handle is provided) is illuminated (including blinking, etc.; the same shall apply hereinafter) in order to notify the driver of the following vehicle that the door 101 has been opened. There is
Therefore, for the same purpose, when an occupant A seated on the seat 10 operates the inner handle of the door 101 to open the door 101, an illuminated area of the seat 10 provided on the door 101 side is illuminated. It is possible to configure α (see FIG. 23) to light up.

With this configuration, the opened door 101 is illuminated by lighting the illuminated area α of the seat 10, and the driver of the following vehicle can be visually notified that the door 101 of the vehicle 100 is open. becomes.
At this time, if the inner side of the door 101 is also lit in conjunction with the lighting of the illuminated area α of the seat 10, the driver of the following vehicle can more clearly see that the door 101 of the vehicle 100 is open. It becomes possible to
Further, with the above configuration, even if the inside of the door 101 is not configured to be illuminated, the open door 101 is illuminated by the light of the illuminated area α of the seat 10, so that the above beneficial effects are obtained. effect can be obtained.

[Configuration example 3-7]
Further, in the configuration example 1-4 described above, the case where the shining region α is provided in the movable portion of the seat 10 has been described, but the seat 10 as a whole may be configured to rotate.
That is, the seat 10 of the driver's seat can rotate outward (that is, face outward) when getting on and off, and the front passenger seat, rear seat, etc. of a welfare vehicle can rotate outward when getting on and off. There is a vehicle 100 configured to: In some cases, the seat 10 such as the driver's seat is configured to be able to rotate inward.

In such a case, as in the case where the seat back 12 is tilted backward, the rotating seat is arranged so as to alert surrounding occupants when the seat 10 rotates outward or inward. It is possible to configure so that the 10 shining areas α are lit (including blinking, etc.; the same shall apply hereinafter).
At that time, in order to accurately inform the occupants on the left and right of the rotating seat 10 and the occupants behind the rotating seat 10 that the seat 10 is rotating, the left and right of the rotating seat 10 (at least the portions facing the seats adjacent to the left and right) and It is preferable to provide a luminous area α on the back surface or the like, and to configure it so that it is lit. By configuring in this manner, it is possible to accurately prevent accidents such as injuries caused by collisions with the rotating seat 10 caused by the rotation of the seat 10 and the surrounding occupants being unaware of the rotation. can be prevented.

On the other hand, the seat cushion 11, seat back 12, etc. of the seat 10 have a uniform hardness of the cushion pad 14, for example, throughout the seat cushion 11 from the viewpoint of comfort, holdability, ease of driving, vibration absorption, and the like. Instead, it may be partially configured differently.
In such a case, as shown in FIG. When a force is applied to this area 14h such as when a person sits on the seat, the cushion pad 14 is not deformed so much, so that a strong force is applied to the glowing area α. Therefore, problems such as damage to the luminous region α may occur.

On the other hand, as shown in FIG. 28(B), if the shining region α of the seat 10 is provided in a portion corresponding to the low hardness region 14s (that is, the soft region) of the cushion pad 14, the occupant A will not be seated. When a force is applied to the lever region 14h, the cushion pad 14 deforms and absorbs the force, so that the force applied to the glowing region α is weakened. Therefore, the shining region α is less likely to be damaged.

Therefore, when the cushion pad 14 such as the seat cushion 11 or the seat back 12 has a high hardness region 14h and a low hardness region 14s, the shining region α corresponds to the low hardness region 14s of the cushion pad 14. It is desirable to provide it in a part.
With this configuration, it is possible to prevent the shining region α from being damaged due to the hardness of the cushion pad 14 .

[Configuration example 3-9]
Further, as shown in FIGS. 28A and 28B, when there is a boundary between the high hardness region 14h and the low hardness region 14s of the cushion pad 14, when a force is applied to that portion, the hardness increases. The cushion pad 14 does not dent so much in the region 14h where the hardness is high, but the cushion pad 14 dents in the region 14s where the hardness is low.
Therefore, if the glowing region α is provided so as to straddle the boundary, there is a possibility that the glowing region α will be damaged by the steps that occur in the cushion pad 14 . Therefore, if there is a boundary between the high-hardness region 14h and the low-hardness region 14s of the cushion pad 14, the shining region α is provided so as not to cross the boundary (provided so as to avoid the boundary). is preferred. At that time, it is preferable to provide it in the region 14s of the cushion pad 14 having a low hardness, as described in the configuration example 3-8.

Note that when the hardness of the cushion pad 14 changes gently (that is, when there is no boundary as described above), a part of the glowing region α provided in the portion corresponding to the low region 14s of the cushion pad 14 becomes the cushion. It may be provided to extend to areas of the pad 14 with higher hardness.

[Application example of configuration example 3-9]
Further, as described above, when there is a boundary between the high hardness region 14h and the low hardness region 14s of the cushion pad 14 (see FIGS. 28A and 28B), the If the shining region α is provided, there is a possibility that the shining region α will be damaged.
That is, if the heater wire 22 or the like is provided so as to straddle the above boundary, the heater wire 22 or the like may be cut or otherwise damaged due to a step generated in the cushion pad 14 when a force is applied. .

Therefore, if there is a boundary between the high hardness region 14h and the low hardness region 14s of the cushion pad 14, the heater wire 22 and the seat heater 20 are preferably provided so as not to cross the boundary. .

[Configuration example 3-10]
Further, at present, technology is being developed for recognizing the voice uttered by the driver with a voice recognition device and controlling the vehicle according to the voice instructions.
Therefore, when the voice recognition device recognizes the voice, it is possible to configure so that the illuminated area α of the sheet 10 is lit (including blinking, etc.; the same shall apply hereinafter) in a predetermined manner.
In this case, for example, if the lighting area α of the seat 10 is lit when the voice recognition device recognizes an instruction uttered by the driver, the lighting of the lighting area α indicates that the instruction has been recognized. It is possible to inform people.

It should be noted that, for example, when the speech recognition device fails to recognize the instruction content of the driver, it is possible to configure the area α to light up in a manner different from that in the case where the support content is recognized. . With this configuration, the driver can understand that the voice recognition device has failed to recognize the content of the instruction and issue the instruction again.
Moreover, the voice recognition device, the sound collecting microphone, and the like may be provided on the seat 10 or may be provided on a place other than the seat 10 .

Then, for example, when the sound collecting microphone of the voice recognition device is provided in the seat 10 (the seat back 12, the headrest 13, etc.), the detection of the biosensor 32, etc. described in the above configuration example 1-13 (see FIG. 13) As in the case of the means, it is desirable to configure so that the shining region α is provided at a position avoiding the sound collecting microphone (that is, at a position where the sound reception by the sound collecting microphone is not disturbed, etc.).
If the luminous area α is provided at a position overlapping the sound collecting microphone, the sound collecting microphone may have difficulty receiving the sound. It is possible to receive sound reliably with the sound collecting microphone.

It goes without saying that the present invention is not limited to the above-described embodiments and configuration examples, and can be modified as appropriate without departing from the gist of the present invention.
