Embodiments of the invention will be described below with reference to the accompanying drawings. In this specification, the front, rear, left, right, and top and bottom refer to the front, back, left, right, and top and bottom as seen from a person sitting on the seat (seated person).
First, the first embodiment will be explained.
As shown in FIG. 1, a seat air-conditioning system 1 of the present embodiment is mounted on a vehicle, specifically, an automobile, and includes a seat body S0 on which a seated person sits, an air conditioner 10, and an air blowing portion 21. , and a blower device 31 .

The seat main body S0 is configured as a vehicle seat, specifically, a vehicle seat mounted in an automobile. The seat body S0 is installed on the floor FL in the vehicle compartment, and has a seat cushion S1, a seat back S2, and a headrest (not shown). The seat cushion S1 is configured by covering a seat cushion frame, which constitutes the frame of the seat cushion S1, with a seat cushion pad P1 and a seat cushion skin U1. The seat back S2 is constructed by covering a seat back frame, which constitutes the frame of the seat back S2, with a seat back pad P2 and a seat back skin U2.

The seat cushion pad P1 has an air passage A1 formed inside and a plurality of air holes H1 communicating with the air passage A1 from the upper surface. As a result, when air (see the dashed arrow) is supplied from the air conditioner 10 into the ventilation path A1, the seat cushion S1 allows the air in the ventilation path A1 to pass through the ventilation hole H1 to the surface facing the seated person. Specifically, it is configured to be able to blow out from the upper surface. Further, the seat back pad P2 has an air passage A2 formed inside and a plurality of air holes H2 communicating with the air passage A2 from the front surface. As a result, when air is supplied from the air conditioner 10 into the ventilation path A2, the seat back S2 allows the air in the ventilation path A2 to flow through the ventilation hole H2 to the surface on the side of the occupant, specifically, the front side. It is configured to be able to blow out from the surface. The skins U1 and U2 have air permeability by forming a plurality of fine through-holes at positions corresponding to the ventilation holes H1 and H2, or are made of a material having air permeability.

The seat body S0 is installed on the floor FL of the vehicle so as to be slidable in the front-rear direction. Specifically, the seat body S0 is installed on the floor FL via a pair of slide rail mechanisms SL (only one of which is shown) spaced apart from each other in the left and right direction. The slide rail mechanism SL has a lower rail SL1 extending longitudinally and fixed to the floor FL, and an upper rail SL2 fixed to the frame of the seat cushion S1. engaged. Accordingly, the seat body S0 is installed so as to be slidable forward and backward with respect to the floor FL.

In this embodiment, the floor FL has a wall 40 provided between a pair of left and right slide rail mechanisms SL. The wall 40 partitions the space SP1 between the floor FL and the seat body S0 installed thereon, and the space SP2 around the space SP1, more specifically, the spaces SP2 on the front, back, left and right sides of the space SP1. is provided in Specifically, the wall 40 is provided so as to rise from the floor FL on the front, rear, right and left sides of the air blowing portion 21, is formed continuously so as to surround the air blowing portion 21, and has a substantially rectangular shape in plan view. .

The air conditioner 10 is a device for adjusting the temperature of the environment in which the seat body S0 is arranged, specifically, the temperature inside the passenger compartment. The air conditioner 10 is provided separately from the seat body S0. Specifically, the air conditioner 10 is provided in the vehicle. The air conditioner 10 is configured to be able to supply cool air and warm air. That is, the air conditioner 10 is configured as a heating, ventilating, air conditioning (HVAC) system. Cool air or warm air from the air conditioner 10 is configured to blow out from an air outlet 11 provided in a vehicle dashboard DB or the like. Also, the air conditioner 10 is connected to an air blowing section 21 by an air conditioning duct 12 provided in the vehicle, so that cool air or warm air from the air conditioner 10 is also blown from the air blowing section 21. It is

The air blowing portion 21 is a cylindrical member, and is provided so as to protrude from the floor FL of the vehicle on which the seat body S0 is installed. Specifically, the air blowing part 21 protrudes upward from the floor FL and is formed in a substantially L shape in a side view that is bent forward. The air blowing part 21 is arranged in a space SP1 between the floor FL and the seat body S0, more specifically in a space SP1 surrounded by the wall 40. As shown in FIG. Thus, the air blowing portion 21 is configured to blow air from the air conditioner 10 toward the space SP1 between the floor FL and the seat body S0.

The air blower 31 is a sirocco fan, and unlike the air conditioner 10, it is provided in the seat body S0. Specifically, the blower device 31 is provided on the seat cushion S1 of the seat body S0 by being attached to the frame of the seat cushion S1 via the bracket BR. The air blower 31 is arranged with the air suction port 31A facing downward. Specifically, the air blower 31 is arranged such that the air suction port 31A faces the space SP1 surrounded by the wall 40 . The air blower 31 has a duct 50 connected to the air outlet 31B, and the duct 50 is connected to the ventilation paths A1 and A2. As a result, the air blower 31 sucks the air in the space SP1 between the floor FL and the seat body S0 by rotating the blades (not shown) and blows the air toward the ventilation paths A1 and A2.

In this embodiment, the blower device 31 has an air suction part 32 . The air suction part 32 is a tubular member for sucking air, and is attached to the air suction port 31A of the blower device 31 . The air suction portion 32 has a funnel-shaped enlarged diameter portion 32A that widens toward the floor FL, in other words, downward.

According to the present embodiment described above, the air from the air conditioner 10 blown into the space SP1 between the floor FL of the vehicle and the seat body S0 installed thereon is blown from the space SP1 by the blower 31. The air can be sucked in and blown out from the surface of the seat body S0 on the side of the seated person through the ventilation paths A1 and A2. Thereby, the air from the air conditioner 10 can be used efficiently.

More specifically, when cold air is supplied from the air conditioner 10, the cold air accumulates on the floor FL. Cool air from the air conditioner 10 can be efficiently used because it can be blown out from the seated person side surface of S0.

Further, when warm air is supplied from the air conditioner 10, the warm air tends to move upward, but the warm air is efficiently sucked in by the air blower 31 arranged on the floor FL, and the occupant of the seat main body S0 is lifted. Since the air can be blown out from the side surface, the warm air from the air conditioner 10 can be efficiently used.

Further, in the present embodiment, the blower device 31 is provided with the air suction portion 32 having the funnel-shaped enlarged diameter portion 32A, so that the air suction portion of the blower device 31 can be enlarged. As a result, the air blown into the space SP1 between the floor FL and the seat body S0 can be efficiently sucked, so that the air from the air conditioner 10 can be used more efficiently.

Further, in this embodiment, the floor FL is provided with the wall 40 provided so as to separate the space SP1 between the seat body S0 and the space SP2 around the space SP1. It is possible to suppress the air blown into the space SP1 between the seat body S0 from flowing out into the space SP2 around the space SP1. Thereby, the air from the air conditioner 10 can be used more efficiently.

Further, according to the present embodiment, even if the seat body S0 is rotatable between a state in which it faces the front of the vehicle and a state in which it faces the rear of the vehicle, as in the conventional technology described above, the air from the air conditioner 10 can be blown out from the surface of the seat body S0 on the seated person side, and the air from the air conditioner 10 can be efficiently used regardless of the direction in which the seat body S0 faces.

In the first embodiment, the floor FL of the vehicle has a wall 40 that separates the space SP1 between the floor FL and the seat body S0 and the space SP2 around the space SP1. However, it is not limited to this. For example, instead of the floor FL, the seat body S0 may have such walls, or both the seat body S0 and the floor FL may have such walls.

Further, in the first embodiment, the wall 40 is continuously formed so as to surround the air blowing portion 21 and has a substantially rectangular shape in a plan view, but the present invention is not limited to this. For example, the walls may be intermittently formed instead of continuous. For example, a plurality of walls may be arranged side by side or front and rear, and there may be gaps between adjacent walls. Further, the wall may be mesh-like, for example, in order to reduce the weight of the vehicle and the seat body. Further, the walls may be provided, for example, only on the front and rear of the air blowing portion, or may be provided only on the left and right of the air blowing portion.

Also, the seat body and the floor may be configured without walls. For example, if there is a dent in the floor of the vehicle that faces the seat body, the air blowing part is provided in the dent, and the air blower is arranged so that the air inlet faces the dent. Since it is difficult for the air blown into the space between the seat body and the seat body to flow out into the surrounding space, a wall that suppresses the outflow of air can be omitted.

Further, in the first embodiment, the funnel-shaped air suction part 32 is attached to the blower device 31, but the present invention is not limited to this. For example, a funnel-shaped air suction part may be provided integrally with the housing of the blower. Further, the air blower may be configured without the funnel-shaped air suction portion.

Next, a second embodiment will be described. In the following description, the same reference numerals are given to the same configurations as in the previously described embodiment, and the description thereof will be omitted as appropriate, and the differences from the previously described embodiment will be described in detail.
As shown in FIG. 2, the seat air-conditioning system 1 of this embodiment includes a seat body S0, an air conditioner 10, an air blower 22, a blower 31, and a first duct 61. As shown in FIG.

In this embodiment, the air blowing part 22 is a cylindrical member, and is provided so as to protrude from the floor FL. Specifically, the air blowing part 22 protrudes upward from the floor FL and is formed in a substantially L shape in a side view that is bent toward the rear. The air blowing part 22 is arranged in the space SP1 between the floor FL and the seat body S0. The air blowing part 22 is connected to the air conditioner 10 by an air conditioning duct 12 and is configured to blow air from the air conditioner 10 .

The first duct 61 is provided to connect the seat body S<b>0 and the air blowing portion 22 . Specifically, the first duct 61 has a first end portion 61A, a second end portion 61B, and an intermediate portion 61C. is connected to the air suction port 31A of the blower 31 . Thus, the first duct 61 is configured to send the air blown from the air blowing portion 22 to the blower device 31, and the blower device 31 is blown from the air blowing portion 22 by rotating the blades (not shown). The air is sucked through the first duct 61 and blown toward the ventilation paths A1 and A2. The first duct 61 has flexibility, for example, by forming a bellows portion or by forming it from a rubber material or the like. The intermediate portion 61C is a portion between the first end portion 61A and the second end portion 61B, extends rearward from the first end portion 61A, then curves into a U shape, The upper portion extends forward and is connected to the second end portion 61B.

As shown in FIG. 3 , the first duct 61 is held by a deformation guide device 70 . The deformation guide device 70 is a device that guides the deformation of the first duct 61 accompanying the forward and backward sliding movement of the seat body S0. The deformation guide device 70 has a structure similar to devices called, for example, a cable protection guide device, a cableveyor (registered trademark), a cableveyor (registered trademark), a cable carrier, or the like.

Specifically, the deformation guide device 70 has a structure in which a plurality of link members 71 are arranged in series and adjacent link members 71 are connected to each other so as to be rotatable about a pin 71A. Each link member 71 has a pair of link portions 72 arranged to face each other and a pair of arm portions 73 provided to connect the pair of link portions 72 . A housing space for housing the first duct 61 is formed between the pair of link portions 72 . The first duct 61 arranged in the accommodation space is supported by an arm portion 73 located on the lower side. As shown in FIG. 4A, the deformable guide device 70 has one end portion 70A fixed to the floor FL near the air blowing portion 22 with the first duct 61 disposed in the housing space. The other end 70B is fixed to the frame of the seat cushion S1 near the blower 31. As shown in FIG.

When the seat body S0 slides forward from the position shown in FIG. 4A to the position shown in FIG. bends and deforms following the forward movement of the end portion 70B. Similarly, when the seat body S0 slides backward from the position shown in FIG. 4A to the position shown in FIG. The guide device 70 bends and deforms following the rearward movement of the end portion 70B. At this time, the bending radius of the substantially U-shaped bent portion of the deformation guide device 70 is kept substantially constant. As a result, the flexible first duct 61 held by the deformation guide device 70 is protected by the deformation guide device 70 while its deformation is guided. The curved portion of 61C (see FIG. 2) is bent and deformed at a predetermined curvature with almost no change in curvature.

According to the present embodiment described above, the air from the air conditioner 10 is sucked by the air blower 31 through the first duct 61 connecting the seat body S0 and the air blowing portion 22, and is passed through the air passages A1 and A2 to the seat body. The air can be blown out from the seated person side of S0. Thereby, the air from the air conditioner 10 can be used efficiently. In addition, by providing the air blower 31 between the duct 50 and the first duct 61, for example, compared to the case where the first duct 61 is directly connected to the duct 50 without providing the air blower 31, the seat body It is possible to ensure the amount of air blown out from the surface of S0 on the side of the seated person.

Further, in this embodiment, the first duct 61 is connected to the air suction port 31A of the blower 31 , so that the air flowing through the first duct 61 can be directly sent to the blower 31 . Thereby, the air from the air conditioner 10 can be used more efficiently.

Further, since the first duct 61 is held by the deformation guide device 70, it is possible to prevent the first duct 61 from freely moving when the seat body S0 slides. As a result, for example, when the seat body S0 slides, the first duct 61 can be prevented from hitting the floor FL or the seat body S0. In addition, since the first duct 61 is held by the deformation guide device 70, when the seat body S0 slides, the first duct 61 is crushed and the cross-sectional area of the first duct 61 is reduced. change can be suppressed. As a result, it is possible to suppress a change in the amount of air flowing through the first duct 61 before and after the seat body S0 slides.

Note that the deformable guide device 70 described in the second embodiment is an example of the deformable guide device according to the invention, and the specific configuration thereof is not limited. Further, in the second embodiment, the first duct 61 is held by the deformable guide device 70, but is not limited to this. For example, even if the seat body slides, the first duct maintains its cross-sectional shape. In addition, if the structure does not cause the curvature of the curved portion to become extremely steep, the configuration may be such that the deformation guide device is not provided. Further, if the seat body does not slide, the deformation guide device can be omitted.

Next, a third embodiment will be described.

Thereby, the first duct 62 is configured to send the air blown from the air blowing portion 22 to the first blower 34 and the second blower 35 via the second duct 80 . The first duct 62 has flexibility, like the first duct 61 of the second embodiment.

Although illustration is omitted, the first duct 62 is held by a deformation guide device having the same configuration as the deformation guide device 70 (see FIG. 3) of the second embodiment, and the deformation guide device moves the seat body. The deformation associated with the forward and backward sliding movement of S0 is guided.

According to the present embodiment described above, the air from the air conditioner 10 is sucked by the air blower 33 through the first duct 62 and the second duct 80, and the air is passed through the air passages A1 and A2 to the seat body S0 on the seated person side. You can blow it out of the face. Thereby, the air from the air conditioner 10 can be used efficiently.

Further, in the present embodiment, the first duct 62 is connected to the second duct 80 that connects the air inlet 34A of the first blower 34 and the air inlet 35A of the second blower 35. Air flowing through the duct 62 can be sent to both the first blower 34 and the second blower 35 through the second duct 80 . As a result, for example, the air flowing through the first duct is first supplied to the first blower 34, and then supplied from the first blower 34 toward the air passage A1 and the second blower 35. Compared to the case, in the configuration in which the blower 33 includes the first blower 34 and the second blower 35, the air blown from the first blower 34 and the air blown from the second blower 35 are balanced. can keep.
