( Reference form 1)
As shown in FIG. 1, an air-conditioned seat 1 of Reference Embodiment 1 is a vehicle seat on which a passenger can sit. This air-conditioned seat 1, like a general vehicle seat, includes a seat frame, a cushion material with the seat frame inside, and a skin material covering the cushion material, all of which are not shown.

The air-conditioned seat 1 includes a seat cushion 2 constituting a seat surface, a seat back 3 constituting a backrest, a headrest 4 provided at the top of the seat back 3, and a seat cushion 2 provided on both sides of the seat cushion 2 in the vehicle width direction X. It is equipped with an armrest 5 that serves as an armrest.

On the front side of the seat cushion 2, an ottoman 2a is provided on which the seated person B can rest his or her feet. The armrest 5 also includes a main body portion 5a with which the elbow of the seated person B substantially contacts, and a support portion 5b that supports the main body portion 5a.

Such an air-conditioned seat 1 is also called a "captain seat." Typically, they are used for second and third row seats in a vehicle, but they can also be used for other seats in the vehicle interior if necessary. Preferably, the air-conditioned seat 1 has a reclining function that allows the inclination angles of the ottoman 2a and the seat back 3 to be changed.

In the air-conditioned seat 1, a movable part 10 is attached to the inner side of each armrest 5 so as to protrude from a portion facing the waist region B1 and thigh region B2 of the seated person B. This movable part 10 has an air-conditioned air blowing part 11 and a driving part 15 built therein.

As shown in FIG. 2, the conditioned air blowing section 11 on the right side in the vehicle width direction We are prepared. The conditioned air blowing section 11 is arranged at a portion of the armrest 5 that faces the waist B1 and thigh B2 of the seated person B.

Note that the left-hand conditioned air blowing section 11 has substantially the same structure as the right-hand conditioned air blowing section 11 except that it has a bilaterally symmetrical structure. Therefore, in the following, only the structure of the conditioned air blowing section 11 on the right side will be described, and a description of the structure of the conditioned air blowing section 11 on the left side will be omitted.

The pad member 12 is made of a breathable and flexible material. Typically, the pad member 12 can be constructed by opening plant fibers such as cotton, animal fibers, chemical fibers, etc. and forming them into a predetermined thickness. Further, a molded body having a structure in which ultrafine fibrous resins are three-dimensionally intertwined, a porous molded body, or the like may be used as the breathable and flexible pad member 12.

The conditioned air nozzle 13 is connected to the conditioned air supply source 14, and its discharge port 13a is arranged inside the pad member 12. Therefore, the conditioned air supplied from the conditioned air supply source 14 is discharged into the pad member 12 through the outlet 13a of the conditioned air nozzle 13. In this case, the number of air-conditioned wind nozzles 13 may be one or more.

The conditioned air supply source 14 is configured such that its temperature, air volume, supply timing, etc. are controlled by the control unit 30. This conditioned air supply source 14 may be dedicated to the air conditioned seat 1, or may also be used to supply conditioned air to the entire vehicle interior.

The drive unit 15 has a function of driving the conditioned air blowing unit 11 from a standby position P1 to an operating position (see operating position P2 in FIG. 3) that is closer to the seated person B than the standby position P1. At this time, the standby position P1 is a position farther from the seated person B than the actuation position P2, and the actuation position P2 is a position closer to the seated person B than the standby position P1.

The air-conditioned seat 1 of this embodiment is configured so that conditioned air is blown out toward the seated person B from the conditioned air blowing section 11 which is set at the operating position P2 by the drive section 15.

The drive unit 15 includes a gas bag 16 connected to a gas supply source 19 via a gas nozzle 18, and two holding plates 17 that hold both sides of the gas bag 16 in the vehicle width direction X.

The gas bag 16 is configured to be inflatable and deflated. The gas bag 16 is typically formed into a bag shape using a resin film, a coated base fabric made of a resin base fabric coated with silicone resin, a rubber sheet, or the like.

The gas bag 16 expands from its initial state when gas is supplied from the gas supply source 19 to the internal space 16a through the gas nozzle 18, and contracts to its initial state when the gas supply from the gas supply source 19 is stopped. The gas flow rate and gas supply timing from the gas supply source 19 at this time are configured to be controlled by the control section 30.

Although the type of gas supplied from the gas supply source 19 to the gas bag 16 does not matter, it is preferable to use air because outside air can be used.

The two holding plates 17 are flat plate members each extending on a plane defined by the vehicle height direction Y and the vehicle length direction Z, with the vehicle width direction X as the plate thickness direction, and are arranged parallel to each other. Although the material of each holding plate 17 does not matter, it is preferably made of a lightweight resin material in order to facilitate the operation of the drive unit 15.

The two holding plates 17 are integrated by being joined to the gas bag 16, and have a function of holding the cross-sectional shape of the movable portion 10 (the cross-sectional shape shown in FIGS. 2 and 3) in a substantially rectangular shape. The distance between the two holding plates 17 in the vehicle width direction X increases as the gas bag 16 expands, and decreases as the gas bag 16 contracts.

The storage bag 20 has elasticity and is configured to accommodate the pad member 12 of the air-conditioned air outlet 11, the gas bag 16 of the drive unit 15, and the holding plate 17. The storage bag 20 includes a front covering section 20a, a rear covering section 20b, and a partition wall section 20c.

The front covering portion 20a is configured to cover the opposing surface 12a of the pad member 12 that faces the seated person B. The rear covering section 20b is joined to the front covering section 20a and is configured to cover the drive section 15.

The partition wall portion 20c partitions the pad member 12 and the gas bag 16, and is joined to the pad member 12 and the right holding plate 17, respectively. Note that, if necessary, the right holding plate 17 may be omitted and the partition wall portion 20c may be directly joined to the gas bag 16.

In this storage bag 20, the front covering part 20a is made of a material with higher air permeability than the partition wall part 20c. Thereby, the conditioned air discharged into the pad member 12 through the outlet 13a of the conditioned air nozzle 13 can be prevented from passing through the partition wall portion 20c from the pad member 12. Therefore, it is possible to obtain the directivity of the flow of the conditioned air so that it passes through the front side covering portion 20a and is directed toward the seated person B.

Next, the operation of the conditioned air blower 11 when it moves from the standby position P1 to the operating position P2 will be described with reference to FIGS. 2 to 4. Such operation of the conditioned air blowing unit 11 is achieved by the control unit 30 controlling the conditioned air supply source 14 and the gas supply source 19.

As shown in FIG. 2, when the gas supply from the gas supply source 19 is stopped and gas is no longer supplied to the internal space 16a of the gas bag 16 through the gas nozzle 18, the gas bag 16 contracts. Then, as the gas bag 16 contracts, the conditioned air blowing section 11 is set to the standby position P1.

The contraction of the gas bag 16 at this time may be caused by a structure in which gas naturally escapes from the gas bag 16 (hereinafter referred to as the "first contraction structure"), or by utilizing the contraction force of the gas bag material itself. (hereinafter referred to as "second contracted structure"), or may be caused by both the first contracted structure and the second contracted structure.

As shown in FIG. 3, when gas supply from the gas supply source 19 is started and gas is supplied to the internal space 16a of the gas bag 16 through the gas nozzle 18, the gas bag 16 expands. As the bag thickness D increases when the gas bag 16 is inflated, the pad member 12 is pressed through the right holding plate 17.

As a result, the conditioned air blower 11 is driven from the standby position P1 indicated by the two-dot chain line to the operating position P2 indicated by the solid line. At this time, the dimension of the movable part 10 in the vehicle width direction Increases to L2.

The timing at which the gas supply source 19 starts supplying gas is not particularly limited, but typically, the timing at which the seated person B inputs a command signal to the control unit 30 using an operation switch or operation panel, or the timing at which the air-conditioned seat It is possible to use the timing when the control unit 30 detects that the seated person B is sitting on the seat 1.

As shown in FIGS. 3 and 4, when the gas bag 16 is inflated, the drive section 15 drives the air-conditioned air blowing section 11 from the standby position P1 to the operating position P2, thereby moving the pad member 12. Bring it closer to seated person B. At this time, the drive section 15 controls the movable section 10 so that it comes into close contact with the waist B1 and thigh B of the seated person B and presses the pad member 12 of the conditioned air blowing section 11 against the waist B1 and thigh B2 . be done.

When the conditioned air A is supplied from the conditioned air supply source 14, the conditioned air A is discharged into the pad member 12 through the outlet 13a of the conditioned air nozzle 13. The conditioned air A is blown out from the movable part 10 from the facing surface 12a of the pad member 12 through the front covering part 20a of the storage bag 20 toward the waist region B1 and thigh region B2 of the seated person B.

Although the timing at which the conditioned air supply source 14 starts supplying the conditioned air A is not particularly limited, it is typically the timing at which the seated person B inputs a command signal to the control unit 30 using an operation switch, an operation panel, etc. Alternatively, the timing at which the control section 30 determines that the conditioned air blowing section 11 has reached the operating position P2 can be used.

On the other hand, when the gas bag 16 is deflated, the drive section 15 drives the conditioned air blowing section 11 from the operating position P2 to the standby position P1 to move the pad member 12 away from the seated person B. At this time, the drive unit 15 is controlled to release the pad member 12 of the conditioned air blower 11 from being pressed against the waist B1 and thigh B2 of the seated person B.

Furthermore, by stopping the supply of the conditioned air A from the conditioned air supply source 14, the conditioned air A blown out from the movable part 10 toward the waist B1 and thigh B2 of the seated person B is stopped.

In the movable part 10, it is preferable to set the bag thickness D of the gas bag 16 when it is deflated so that the first dimension L1 at the standby position P1 of the air-conditioned air blowing part 11 is kept as small as possible. Thereby, the movable part 10 is less likely to get in the way of the seated person B when the air-conditioned air blowing part 11 is in the standby position P1.

Regarding the control in which the drive unit 15 drives the air-conditioned air blower 11 to the operating position P2, the operating position P2 may be a fixed position predetermined based on initial information such as the standard body shape of the seated person B. Alternatively, the position may be selected by the seated person B using an operation switch or operation panel, or the position may be set by automatically detecting the actual body shape and seating position of the seated person B individually. It may be an individually set position.

When the operating position P2 is the above-mentioned fixed position, the control for driving the air-conditioned air blower 11 becomes simple. When the operating position P2 is the above-mentioned selected position, the seated person B can arbitrarily change the position of the conditioned air blower 11. When the operating position P2 is the above-mentioned individually set position, the air-conditioned air outlet 11 can be automatically adjusted to an appropriate position.

Next, the effects of the above-mentioned Reference Embodiment 1 will be explained.

In the air-conditioned seat 1 described above, the conditioned air blowing section 11 is driven by the driving section 15 between the standby position P1 and the operating position P2. Then, with the conditioned air blowing section 11 set at the operating position P2, the conditioned air A is blown out from the conditioned air blowing section 11 toward the seated person B.

According to this air-conditioned seat 1, by setting the conditioned air blowing part 11 to the operating position P2, the distance from the conditioned air blowing part 11 to the seated person B is kept small, and warm air whose temperature is controlled can be generated. Cold air can be blown out as conditioned air A toward the seated person B. Thereby, the comfort of the seated person B can be improved by the conditioned air A. At this time, by bringing the conditioned air blower 11 closer to the seated person B, the influence of differences in the physique of the seated person B, changes in posture, etc. can be reduced.

On the other hand, by moving the conditioned air blower 11 away from the seated person B at the standby position P1, the conditioned air blower 11 is less likely to interfere with the seating person B when the conditioned air A is not required. Thereby, it is possible to prevent the movement of the seated person B from being suppressed by the air-conditioned air blowing section 11 and the comfort from being reduced.

As a result, it becomes possible to provide an air-conditioned seat 1 with excellent comfort.

According to the above-mentioned air-conditioning sheet 1, the flow of the conditioned air A discharged from the outlet 13a of the conditioned air nozzle 13 into the inside of the pad member 12 is ensured by the breathability of the pad member 12, and the seated person B can When the seated person B interferes with the wind blowing part 11, the pad member 12 can flexibly receive the seated person B.

According to the air-conditioning sheet 1 described above, the air-conditioned air blowing section 11 is driven between the standby position P1 and the operating position P2 by a simple structure that takes advantage of the fact that the bag thickness D changes due to expansion and contraction of the gas bag 16. By doing so, the pad member 12 can be brought closer to the seated person B or moved away from the seated person B.

According to the above air-conditioned seat 1, the gap between the seated person B and the air-conditioned air blower 11 is eliminated or minimized when the air-conditioned air blower 11 is in the operating position P2. Heat transfer performance with the wind A can be improved.

According to the air-conditioned seat 1, the flexible pad member 12 is pressed against the seated person B to support the seated person B when the air-conditioned air blowing section 11 is in the operating position P2, thereby improving the sense of security when the seated person B is seated. The conditioned air A can be supplied while the person B is comfortably and appropriately restrained. This allows the seated person B to have a high-quality sleep on the air-conditioned seat 1.

According to the above-mentioned air conditioning sheet 1, by storing the pad member 12 and the gas bag 16 in the elastic storage bag 20, the storage bag 20 hardly obstructs the movement of the pad member 12 and the gas bag 16, and the pad The appearance is better than when the member 12 and the gas bag 16 are housed separately.

According to the air-conditioned seat 1, the temperature-controlled warm air or cold air is used as the conditioned air A while keeping the distance from the air-conditioned air outlet 11 to the waist B1 and thigh B2 of the seated person B small. Air can be blown toward the waist B1 and thigh B2 of the seated person B. Furthermore, since the conditioned air blowing section 11 moves between the standby position P1 and the operating position P2 at a position close to the waist B1 and thigh B2 of the seated person B, the moving distance of the conditioned air blowing section 11 can be kept small. I can do it. Thereby, the movable part 10 can be downsized.

As a modification particularly related to the above-mentioned reference form 1, in the above-mentioned air-conditioned seat 1, the movable part 10 is a first movable part corresponding to the waist region B1 of the seated person B, and a first movable region corresponding to the thigh region B2 of the seated person B. It is also possible to adopt a structure in which the first movable part and the second movable part are separately driven.

Further, in the air-conditioned seat 1 described above, the movable part 10 is arranged in a recessed part of the inner wall surface of each armrest 5, so that the movable part 10 is approximately flush with the inner wall surface of each armrest 5. can also be adopted.

In addition, in the air-conditioned seat 1 described above, the movable part 10 may be attached to a part of the air-conditioned seat 1 other than the armrest 5 (for example, the seat back 3, etc.), or the movable part 10 may be attached to an element in the vehicle interior other than the air-conditioned seat 1. It is also possible to adopt a structure in which it is attached to a trim (for example, a trim, etc.).

Embodiment 1 related to Reference Embodiment 1 will be described below with reference to the drawings. In Embodiment 1 , the same elements as those in Reference Embodiment 1 are given the same reference numerals, and descriptions of the same elements will be omitted.

(Embodiment 1 )
As shown in FIG. 5, the air conditioning sheet 101 of the first embodiment includes, in addition to the movable part 10 of the first embodiment, one movable part 110 similar to the movable part 10 and two movable parts 210. This is different from the air conditioning sheet 1 of Reference Embodiment 1 in this point.

The air conditioning sheet 101 is built in the movable part 110 in addition to the first conditioned air blowing part 11A built in the movable part 10, when the conditioned air blowing part 11 of the reference form 1 is the first air conditioned wind blowing part 11A. A second conditioned air blowing section 11B and a third conditioned air blowing section 11C built into each movable section 210 are provided.

The second air-conditioned air blowing part 11B is arranged in a part of the seat back 3 that faces the neck part B3 of the seated person B (see FIG. 6). The third conditioned air blower 11C is disposed in a portion of the headrest 4 that faces the head B4 of the seated person B (see FIG. 6).

Both the conditioned air outlets 11B and 11C have a different overall shape compared to the first air conditioned air outlet 11A, but the internal structure and operation are substantially the same, and the inside of the conditioned air outlets 11B and 11C is Reference is made to FIGS. 2 and 3 for structure and operation. That is, the air-conditioned air blowing units 11B and 11C are driven by drive units 115 and 215 similar to the drive unit 15, respectively, between a standby position and an operating position closer to the seated person than the standby position. .

As shown in FIG. 6, the conditioned air blowing units 11A, 11B, and 11C are all set at their respective operating positions. At this time, the movable portion 10 comes into close contact with the waist B1 and thigh B2 of the seated person B and presses the pad member against the waist B1 and thigh B2. Moreover, the movable part 110 closely contacts the neck B3 of the seated person B and presses the pad member against the neck B3. Moreover, the movable part 210 closely contacts the head B4 of the seated person B and presses the pad member against the head B4. Then, conditioned air A is blown out from each of the conditioned air blowing parts 11A, 11B, and 11C.

At this time, the air-conditioned air blowing parts 11A, 11B, and 11C of the air-conditioned seat 101 cover almost the whole body of the seated person B, so the air-conditioned seat 101 can also be referred to as a "whole-body enveloping seat."

Note that the three conditioned air blowing units 11A, 11B, and 11C may have a common supply source of the conditioned air A, or may be provided individually. When the supply sources of the conditioned air A are individually provided, the temperature of the conditioned air A blown out by each of the three conditioned air blowing units 11A, 11B, and 11C is adjusted individually to a temperature suitable for each part of the seated person B. Preferably controlled. Thereby, when the seated person B sleeps on the air-conditioned seat 101, it becomes possible to further improve the quality of sleep.

The other configurations are the same as those of reference form 1.

According to the first embodiment described above, in addition to the waist region B1 and thigh region B2 of the seated person B, the air conditioning air blowing units 11B and 11C are brought close to the neck region B3 and head B4 of the seated person B, and the air conditioning is performed. Conditioned air A can be blown out from the wind blowing parts 11B and 11C. Thereby, compared to Reference Embodiment 1, the comfort of the seated person B can be further improved.

In addition, the same effects as those of Reference Embodiment 1 are achieved.

As a modification particularly related to the first embodiment described above, it is also possible to adopt a structure in which one of the two conditioned air blowing portions 11B and 11C is omitted in the air conditioning sheet 101.

The present invention is not limited to the above-described embodiments, and various applications and modifications can be made without departing from the purpose of the present invention.

In the above-described embodiment, the case where the air-conditioned air blowing unit 11 (11A, 11B, 11C) is driven from the standby position to the use position by using the expansion and contraction of the gas bag 16 has been exemplified. Alternatively, an electric motor or other actuator (for example, an air cylinder or a hydraulic cylinder) may be used as the drive unit.

In the above embodiment, the air-conditioned seats 1, 101 are illustrated as vehicle seats, but the structure of these air-conditioned seats 1, 101 can be applied not only to vehicle seats but also to vehicles such as airplanes, ships, trains, buses, etc. It can also be applied to seats and seats for buildings such as movie theaters and theaters.
