Similar to the backrest portion 25a, the seating portion 21a includes a seat pad 22a and a skin member 23a that covers the seat pad 22a. The seat pads 22a and 26a are made of an elastically deformable material, for example, an open-cell foamed polyurethane. The seat pads 22a and 26a have a sufficiently large thickness dimension with respect to the skin members 23a and 27a. The seat pads 22a and 26a are cushion members that absorb the load of a seated occupant by elastic deformation and support the occupant. The seat pads 22a and 26a have air passages 220a and 260a through which air driven by a blower device passes.

  The skin members 23a and 27a are members that cover the seat pads 22a and 26a and are in direct contact with the seated person. The skin member 23a covers the seat pad 22a of the seating portion 21a and has a seating surface 230a in the seating portion 21a. The seating surface 230a is a surface that can contact the buttocks and thighs of the occupant seated in the driver's seat 20a. The seating surface 230a corresponds to the driver seating surface in the claims. The skin member 27a covers the seat pad 26a of the backrest portion 25a, and forms a backrest surface 270a in the backrest portion 25a. The backrest surface 270a is a surface on which the back of an occupant seated in the driver's seat 20a can come into contact. The backrest surface 270a corresponds to the driver seat backrest surface in the claims. The skin members 23a and 27a have air permeability. The skin members 23a and 27a are provided by a member in which a plurality of holes are formed so as to be air permeable or a material having air permeability. For example, leather or fabric can be used for the skin members 23a and 27a. The blown air that has passed through the air passages 220a and 260a passes through the air-permeable skin members 23a and 27a and blows out from the seating surface 230a and the backrest surface 270a into the vehicle interior.

  The backrest 25a has a blower 35a inside. The backrest 25a has an air passage 260a through which air driven by the blower 35a can pass. The air passage 260a is formed inside the seat pad 26a. The air passage 260a is formed so that the blown air can pass through the vent hole of the skin member 23a. For example, it can be provided by a centrifugal fan. The back portion 28a of the backrest portion 25a is formed of the same member as the skin member 27a, and has a ventilation hole through which air blown rearward passes.

  The seating part 21a has a blower 31a. The seating portion 21a sucks air from behind the driver seat 20a and blows it forward, independently of the backrest portion 25a. The blower 31a is attached to the lower surface of the seating portion 21a, for example, between the seating portion 21a and the floor of the passenger compartment. The blower 31a has the same structure as the blower 35a, and includes a casing having a suction port 32a and a blower outlet 33a and a fan accommodated in the casing. The fan is a centrifugal blower fan similar to the fan of the blower 35a, for example. The blower 31b is provided, for example, with the suction port 32a facing upward. The suction port 32a is connected to the air passage 220a so that the air flowing through the air passage 220a can flow in. Thereby, the air blower 31a can suck the air sucked from the seating surface 230a and circulated through the air passage 220a. The fan is accommodated in the casing so that the rotation axis thereof is directed in the vertical direction. The blower outlet 33a is configured to open downward, for example, and at least a part of the blown air flows backward.

The blower 31a and the blower 35a correspond to the first blower in the claims.

  The partition part 40a is provided between the seat part 21a and the floor part of the passenger compartment in front of the air outlet 33a. The partition part 40a prevents the air blown from the outlet 33a from moving forward. The partition part 40a has, for example, a width direction dimension comparable to the width direction dimension of the seating part 21a, and is formed by a plate member extending from the seating part 21a to the vicinity of the floor part of the passenger compartment. The partition portion 40a corresponds to the driver seat side partition portion in the claims.

  Next, the configuration of the passenger seat 20b will be described with reference to FIG. The passenger seat 20b sucks air from behind and blows out air from the seating surface 230b and the backrest surface 270b. The seating surface 230b corresponds to a passenger seat seating surface in claims, and the backrest surface 270b corresponds to a passenger seat backrest surface in claims. The passenger seat 20b has the same configuration as that of the driver seat 20a except that the configurations of the blowers 31b and 35b are different. That is, the passenger seat 20b includes a seating portion 21b and a backrest portion 25b. The backrest 25b includes a seat pad 26b and a skin member 27b that covers the seat pad 26b. The seating portion 21b includes a seat pad 22b and a skin member 23b that covers the seat pad 22b. The seat pads 22a and 26a have air passages 220b and 260b through which air driven by the blowers 31b and 35b passes. The seating portion 21b corresponds to the passenger seat seating portion in the claims, and the backrest portion 25b corresponds to the passenger seat backrest portion in the claims.

  The air blower 31b is attached to the lower surface of the seating part 21b between the seating part 21b and the floor part of the passenger compartment, for example, like the air blower 31a. The blower 31b includes a casing having an inlet 32b and an outlet 33b and a fan accommodated in the casing. The fan is, for example, a centrifugal blower fan similar to the blower 31a. The blower 31b is provided, for example, with the suction port 32b facing downward. The fan is accommodated in the casing so that the rotation axis thereof is directed in the vertical direction. In the blower 31b, the blower outlet 33b is connected to the air passage 220b so that the blown air blown from the blower outlet 33b can flow through the air passage 220b. Thereby, the blast air blown from the blower outlet 33b of the blower 31b passes through the skin member 23b after flowing through the air passage 220b and blows off from the seating surface 230b. The suction port 32b corresponds to the passenger seat seating suction portion in the claims.

  The partition portion 40b is provided between the seating portion 21b and the floor of the passenger compartment in front of the suction port 32b. The partition portion 40b restricts the air in front of the passenger seat 20b from being sucked into the suction port 32b. The partition part 40b has, for example, a width direction dimension comparable to the width direction dimension of the seat part 21b, and is formed by a plate member extending from the seat part 21b to the vicinity of the floor of the passenger compartment. The partition portion 40b corresponds to the passenger seat side partition portion in the claims.

  The backrest part 25b has a blower 35b inside. The air blower 35b includes a casing having a suction port 36b and a blower outlet 37b and a fan accommodated in the casing. The fan is, for example, a centrifugal blower fan similar to the blower 31b. The blower device 35b is disposed, for example, behind the backrest portion 25b, and is attached to the skeleton member of the passenger seat 20b with the suction port 36b facing away from the backrest surface 270b. The suction port 36b sucks air from behind the passenger seat 20b through the back portion 28b.

  The back portion 28b is formed of the same member as the skin member 27b, and a ventilation hole through which air sucked from the rear passes is formed. The back part 28b is provided so that the back side of the backrest part 25b may be covered. Therefore, the air behind the passenger seat 20b is sucked from the back portion 28b into the backrest portion 25b. The air outlet 37b is connected to the air passage 260b so that the blown air can flow through the air passage 260b. As a result, the blown air blown from the outlet 37b of the blower 35b flows through the air passage 260b and then passes through the skin member 27b and blows out from the backrest surface 270b. The blower 31b and the blower 35b correspond to the second blower in the claims.

  The control device 50 controls the operation of each blower in the seat blower 1. The control device 50 includes a microcomputer including a storage medium readable by a computer as a main hardware element. The storage medium is a non-transitional physical storage medium that stores a predetermined program readable by a computer in a non-temporary manner. The storage medium can be provided by a semiconductor memory or a magnetic disk. The means and / or function provided by the control device 50 can be provided by software recorded in a storage medium and a computer that executes the software, software only, hardware only, or a combination thereof. For example, if the controller 50 is provided by an electronic circuit that is hardware, it can be provided by a digital circuit including a number of logic circuits, or an analog circuit.

  The control device 50 is provided by, for example, an air conditioner ECU (Electronic Control Unit) that controls the vehicle air conditioner 100. The control device 50 controls the opening degree of the air mix door, the blower blowing amount, the compressor discharge amount, and the like. The control device 50 is connected to a plurality of sensors and can receive a detection signal from each sensor. Examples of the plurality of sensors include an inside air temperature sensor, an outside air temperature sensor, a solar radiation sensor, and a seating sensor. The control device 50 performs various calculations and processes using these detection signals and the stored air conditioning control program, and outputs control signals for controlling various air conditioning functional components that contribute to vehicle interior air conditioning. The air conditioning functional parts include a compressor, a blower, an inside / outside air switching door, an air mix door, a blow-out mode door, and the like.

  Next, the air flow formed in the passenger compartment by the seat blower 1 will be described. The seat blower 1 starts its operation when an occupant turns on an operation switch of the seat blower 1 provided on, for example, an instrument panel.

  When the operation switch is turned on, the control device 50 controls the blower devices 31a, 35a of the driver seat 20a and the blower devices 31b, 35b of the passenger seat 20b, and starts the blowing. The driver's seat 20a sucks air into the interior from the seating surface and the backrest surface by the blowers 31a and 35a. The sucked air passes through the air passages 220a and 260a, respectively. The air inside the backrest portion 25a is blown out from the rear portion 28a to the rear, and the air inside the seating portion 21a is blown out from the outlet 33a to the rear. As described above, the driver's seat 20a forms an air flow that sucks air from the front of the driver's seat 20a and blows it backward, as indicated by the dashed arrows in FIG.

  The passenger seat 20b sucks air from the back portion 28b in the backrest portion 25b and from the suction port 32b in the seating portion 21b by the blowers 31b and 35b. The sucked air passes through the air passages 220b and 260b, and is then blown out from the seating surface 230b and the backrest surface 270b. As described above, the passenger seat 20b forms an air flow that sucks air from the rear of the passenger seat 20b and blows it forward, as indicated by broken arrows in FIG.

  The conditioned air blown from the air vent of the vehicle air conditioner 100 by the driver seat 20a is sucked from the front of the driver seat 20a and blown backward. Thus, the conditioned air can easily reach the rear area of the driver seat 20a, that is, the rear area where the rear seat is provided in the passenger compartment. Further, the conditioned air that reaches the rear region by the passenger seat 20b is sucked from the rear of the passenger seat 20b and blown forward.

  As described above, as indicated by the dashed arrow in FIG. 1, the conditioned air flows from the front of the driver seat 20a to the rear of the driver seat 20a, and after flowing through the rear region in the vehicle width direction, from the rear of the passenger seat 20b. A series of conditioned airflows flowing forward are formed. Thereby, since the conditioned air is distributed throughout the vehicle interior, the entire vehicle interior can be efficiently air-conditioned. Further, since the conditioned air easily flows in the vicinity of the inside air introduction port provided in front of the passenger seat 20b, the air near the inside air introduction port can be easily air-conditioned. Therefore, when the vehicle air conditioner 100 is operating in the inside air circulation mode, it becomes easier to suck air conditioned from the inside air introduction port, and the power for air conditioning the air sucked by the vehicle air conditioner 100 is reduced. It becomes possible to do.

  Next, the effect which the sheet | seat air blower 1 of 1st Embodiment brings is demonstrated. The seat blower 1 includes blower devices 31a and 35a that drive air in the passenger compartment. The seat blower 1 includes a driver seat 20a that sucks air from the front by the blowers 31a and 35a and blows it backward. The seat blower 1 includes blower devices 31b and 35b that drive air in the passenger compartment, and includes a passenger seat 20b that sucks air from the rear by the blowers 31b and 35b and blows it forward.

  According to this, the seat blower blows air from the front to the rear in the driver seat, and blows air from the rear to the front in the passenger seat. Therefore, the conditioned air from the vehicle air conditioner can be blown from the front to the rear by the driver seat, and further from the rear to the front by the passenger seat. Thereby, the conditioned air can be spread over the entire vehicle interior. Furthermore, the conditioned air can be blown in front of the passenger compartment, and the conditioned air can be supplied near the inside air inlet. For this reason, the motive power of the vehicle air conditioner required for air-conditioning the air sucked from the inside air inlet can be suppressed. As described above, it is possible to provide a seat blower that can air-condition the entire vehicle interior and reduce the power of the vehicle air conditioner. In particular, when the inside air introduction port is provided in front of the passenger seat 20b as in the seat blower 1 of the first embodiment, the conditioned air is directly blown to the vicinity of the inside air introduction port by the passenger seat 20b. be able to. For this reason, the air conditioner 100 for vehicles can perform the air conditioning by internal air circulation more efficiently.

  The driver's seat 20a includes a seating portion 21a on which an occupant is seated and a backrest portion 25a that supports the back of the seated occupant. The seating portion 21a includes a seating surface 230a that sucks air from the front, and a blower outlet 33a that blows out the air sucked from the seating surface 230a to the rear. The backrest portion 25a includes a backrest surface 270a that sucks air from the front, and a back portion 28a that blows out the air sucked from the backrest surface 270a rearward. The passenger seat 20b includes a seating portion 21b on which a passenger sits and a backrest portion 25b that supports the back of the seated passenger. The seating portion 21b has a suction port 32b through which air behind is sucked and a seating surface 230b that blows out air sucked from the suction port 32b. The backrest portion 25b has a back portion 28b into which air behind is sucked, and a backrest surface 270b that blows out air sucked from the back portion 28b forward.

  According to this, in the driver's seat 20a, air can be sucked from the front and the rear from the seat portion 21a and the backrest portion 25a. Further, in the passenger seat 20b, air can be sucked from the rear and blown forward from each of the seating portion 21b and the backrest portion 25b. Thus, the amount of conditioned air blown by the sheets 20a and 20b can be increased. Therefore, the conditioned air can be more widely distributed throughout the vehicle interior.

(Second Embodiment)
In the second embodiment, a modification of the sheet blower in the first embodiment will be described. In FIG. 4, the constituent elements having the same reference numerals as those in the drawing of the first embodiment are the same constituent elements and exhibit the same operational effects.

  The seating part 21a of the driver's seat 20a in the second embodiment has a blower 2031a. The blower 2031a is provided on the lower surface of the seating portion 21a, for example, like the blower 31a. As for the air blower 2031a, the blower outlet 2033a is connected with the air passage 220a. The suction port 2032a of the blower 2031a is opened downward, for example, and is configured to suck air from at least the front of the driver seat 20a. Thereby, the seating portion 21a can suck air from the front of the driver seat 20a and blow it out from the seating surface 230a below the seating surface 230a. The suction port 2032a corresponds to the driver seat seating suction portion in the claims. The seat blower 1 may be configured to operate in conjunction with the vehicle air conditioner 100 by being controlled to operate when the vehicle air conditioner 100 is in the FOOT mode.

  Next, the air flow formed by the driver seat 20a will be described. The seating portion 21a sucks air in front of the driver's seat 20a from the suction port and blows it out from the seating surface 230a. The backrest part 25a sucks in air blown out from the seating surface 230a and air in front of the backrest part 25a, and blows out backward from the back part 28a. The driver's seat 20a can inhale more concentrated air at the feet of the occupant by the seating portion 21a. Thereby, when the vehicle air conditioner 100 is operating in the FOOT mode, the conditioned air can be effectively blown from the front to the rear.

  The partition portion 2040a is provided behind the suction port 2032a and between the seating portion 21a and the passenger compartment floor. Partition part 2040a regulates that the air behind driver's seat 20a is sucked into suction port 2032a. The partition portion 2040a has, for example, a width direction size that is substantially the same as the width direction size of the seat portion 21a, and is formed by a plate member that extends from the seat portion 21a to the vicinity of the floor of the passenger compartment. The partition portion 2040a corresponds to the driver seat side partition portion in the claims.

(Third embodiment)
3rd Embodiment demonstrates the modification of the sheet | seat air blower in 1st Embodiment. In FIG. 5, components given the same reference numerals as those in the drawing of the first embodiment are the same components and have the same operational effects.

  The seating portion 21b of the passenger seat 20b in the third embodiment has a blower 3031b. The blower 3031b is provided on the lower surface of the seating portion 21b, for example, like the blower 31a. The blower 3031b has a suction port 3032b connected to the air passage 220b. The blower outlet 3033b of the blower 3031b is configured to open, for example, downward, and at least a part of the blown air flows forward. Thereby, the seating part 21b can blow out the air sucked from the seating surface 230b to the front of the passenger seat 20b below the seating surface 230b. Or the blower outlet 3033b may open toward back so that the blown-out air may flow forward reliably. The air outlet 3033b corresponds to a passenger seat seating outlet in the claims.

  Next, the air flow formed by the passenger seat 20b will be described. The seating portion 21b sucks at least a part of the air blown from the backrest surface 270b of the backrest portion 25b into the inside from the seating surface 230b. The air sucked into the seat portion 21b flows through the air passage 220b, and then is sucked into the blower 3031b from the suction port 3032b and blown out from the blowout port 3033b. The air blown out from the air outlet 3033b flows to the front of the seating portion 21b. With the above air flow, the passenger seat 20b can concentrate air on the feet of the passenger and blow the conditioned air. Accordingly, the conditioned air can be blown more concentrated near the inside air inlet of the vehicle air conditioner 100 that opens near the feet of the passenger. As a result, the power of the vehicle air conditioner 100 can be further suppressed.

  The partition part 3040b is provided between the seating part 21b and the floor of the passenger compartment, behind the outlet 3033b. The partition part 3040b restricts the air blown from the outlet 3033b from being blown behind the passenger seat 20b. The partition part 3040b has, for example, a width-direction dimension comparable to the width-direction dimension of the seating part 21b, and is formed by a plate member that extends from the seating part 21b to the vicinity of the floor of the passenger compartment. The partition portion 3040b corresponds to the passenger seat side partition portion in the claims.

(Fourth embodiment)
4th Embodiment demonstrates the modification of the sheet | seat air blower in 1st Embodiment. The seat blower 1 of the fourth embodiment starts blowing in cooperation with the operation of the vehicle air conditioner 100. The blowing control of the sheet blowing device 1 executed by the control device 50 will be described with reference to the flowchart of FIG. The control device 50 executes the process of the flowchart of FIG. 6 when the vehicle air conditioner 100 is in operation, for example.

  First, in step S10, the control device 50 determines whether or not the vehicle air conditioner 10 has started a cooling operation or a heating operation. Here, whether or not the cooling operation is started can be determined based on whether or not the air in the vehicle air conditioner 100 is cooled and blown into the vehicle interior. Whether or not the heating operation is started can be determined based on whether or not the air in the vehicle air conditioner 100 is heated and blown into the passenger compartment. The control device 50 determines that the cooling operation or the heating operation is started, for example, when the compressor of the vehicle air conditioner 100 starts operating and the refrigerant starts to circulate in the refrigeration cycle. The control device 50 may determine that the vehicle air conditioner 100 has started the heating operation when the blown air passes through the heater core of the vehicle air conditioner 100.
