(First embodiment)
Hereinafter, a first embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a cross-sectional view schematically showing the internal structure of the vehicle seat 10 in the present embodiment. In the figure, arrows in the up / down and front / rear directions indicate the up / down direction in the vehicle mounted state.

  The vehicle seat 10 is used as a front seat, that is, a driver seat or a passenger seat, and supports a seat surface portion 10a that supports a butt portion of an occupant (a seated person), and a back portion and a waist portion of the occupant. A backrest portion 10b, a headrest 10c that supports the head of the occupant, and a seat base 10d that is fixed to the vehicle floor 1 and supports the seat surface portion 10a.

  The net 11 forming the skin member of the backrest portion 10b is stretched with a predetermined tension, and the seat 11 is supported by the tension of the net 11 to receive the occupant. The net 11 is a net-like member made of a knitted fabric, and its end is wound around a frame-like frame 12 via a pad 13.

  The frame 12 is a member made of a metal pipe member. The pad 13 is a member made of an elastic resin material such as polyurethane foam.

  On the back surface (back surface) side of the net 11, a back board 14 that covers the back surface of the backrest portion 10b is disposed. The backboard 14 is a member that has a predetermined rigidity and functions as a protection board that protects the occupant from an external force such as kicking of the rear seat occupant or an internal collision.

  The backboard 14 is disposed so as to extend in the vertical direction at a predetermined distance from the net 11 and is fixed to the frame 12 by appropriate fixing means (not shown). A blower 15 that generates an air flow is integrally disposed at the lower end of the backboard 14.

  2A is a schematic front view of the backboard 14, and FIG. 2B is a cross-sectional view taken along the line AA in FIG. 2A. The backboard 14 includes a substantially flat main body 16 and a duct member 17 disposed on the front side of the main body 16.

  The duct member 17 has a substantially U-shaped cross-sectional shape with the main body 16 side opened. Therefore, a space 14 a surrounded by the duct member 17 and the backboard body 16 is formed in the backboard 14.

  The inlet side end portion (the lower end portion in FIG. 2A) of the space 14 a in the backboard 14 is connected to the blower 15. As a result, the space 14a constitutes a duct passage through which the blown air flows. In other words, the backboard 14 also serves as a duct passage forming member.

  The duct member 17 is formed with a plurality of air outlets 17a communicating with the duct passage 14a and opening toward the net 11 side. The air that has flowed through the duct passage 14a and is blown out from the blowout port 17a is blown out through the breathable net 11 toward a portion (for example, the middle part of the scapula or the armpit) where the occupant is particularly likely to sweat. The shape and arrangement of the duct passage 14a and the opening area, the number and arrangement of the air outlet 17a can be appropriately set in consideration of passenger comfort.

  The backboard main body 16 and the duct member 17 can be resin-molded, for example. The backboard body 16 and the duct member 17 can be fixed by heat welding, ultrasonic welding, or the like. Incidentally, in consideration of safety at the time of a vehicle collision, the duct member 17 has a trapezoidal shape, an arc shape, or the like so that the duct member 17 is easily crushed when the duct member 17 comes into contact with an occupant. The material 17 is preferably an elastomer or a foam material.

  FIG. 3A is a schematic bottom view of the backboard 14 and the blower 15, and FIG. 3B is a cross-sectional view taken along line BB in FIG. A locking structure 17b that locks the blower 15 so as to fix the blower 15 is provided at the end of the duct member 17 on the blower 15 side.

  Thereby, the structure for fixing the air blower 15 is simplified and the cost is reduced. In addition, FIG. 3 is only what shows typically an example of the latching structure of the air blower 15 and the duct member 17, and it can use various latching structures, without being limited to this.

  It is possible to attach the wind direction guide 18 shown to Fig.4 (a), the opening-and-closing mechanism 19 shown to FIG.4 (b), etc. to the blower outlet 17a. The wind direction guide 18 adjusts the flow direction of the blast air in the blower outlet 17a by the louver 18a. The opening / closing mechanism 19 is configured to switch between the flow and blocking of the blown air at the air outlet 17a by opening and closing the air outlet 17a with the louver 19a.

  The wind direction guide 18 and the louvers 18a, 19a of the opening / closing mechanism 19 can be moved according to the passenger's preference and physique. In the example of FIG. 4, the wind direction guide 18 and the opening / closing mechanism 19 are moved by a manual operation force, but the wind direction guide 18 and the opening / closing mechanism 19 may be moved by a driving force such as an electric actuator.

  Further, the position in the blowing direction that suits each passenger may be stored in a control device (ECU) (not shown), and the ECU may move the wind direction guide 18 and the opening / closing mechanism 19 based on the stored data.

  As shown in FIG. 1, the basic structure of the seat surface portion 10 a of the vehicle seat 10 is the same as that of the backrest portion 10 b, and the occupant is received by the tension of the net 20 that forms the skin member. Is wound around a frame-like frame 21 via a pad 22.

  As a difference between the seat surface portion 10a and the backrest portion 10b, the seat surface portion 10a has no component corresponding to the backboard 14 in the backrest portion 10b. For this reason, in the seat surface part 10a, it becomes the structure which has arrange | positioned the several air blower 23 for every site | part which a passenger | crew easily sweats. These blowers 23 are fixed to the frame 21 by brackets (not shown).

  Next, the effect by the said structure is demonstrated. Since the duct passage 14a is formed in the backboard 14, the blown air from one blower 15 can be distributed to the plurality of outlets 17a. For this reason, compared with the case where the air blower 15 is provided for every some blower outlet 17a, cost can be reduced significantly.

  Further, since the blower 15 and the duct member 17 are integrated with the backboard 14, the number of fastening parts for the blower 15 and the duct member 17 can be reduced. Further, since the back boat 14 and the blower 15 can be integrated in advance, there is a merit that it is easy to assemble. For this reason, not only can the cost be reduced, but also the appearance inside the sheet that can be seen through the net 11 can be improved.

  Further, if the shape of the duct passage 14a is changed, the position and the number of the air outlets 17a can be set arbitrarily, so that passenger comfort can be easily improved without causing an increase in cost.

  Further, by providing the wind direction guide 18 and the opening / closing mechanism 19 at the air outlet 17a, the wind direction and the air volume can be arbitrarily adjusted according to the passenger's preference.

  Further, the duct member 17 is easily crushed when the duct member 17 comes into contact with an occupant by making the cross-sectional shape of the duct member 17 trapezoidal or arcuate, or the duct member 17 is made of an elastomer or foam material. Therefore, safety in the event of a vehicle collision can also be secured.

(Second Embodiment)
In the first embodiment, the cross-sectional shape of the duct member 17 is substantially U-shaped, but in the second embodiment, the front surface of the duct member 17 is made flat as shown in FIG. ing. FIG. 5A shows a state in which the backboard 14 is viewed from the front side.

  Specifically, the duct member 17 is formed in a flat plate shape as a whole, and the duct member 17 and the backboard body portion 16 are formed on the back surface of the duct member 17 by forming a rib portion 17c protruding toward the backboard body portion 16 side. A duct passage 14a is formed between the two.

  In the said 1st Embodiment, since the cross-sectional shape of the duct member 17 is made into substantially U shape, uneven | corrugated shape will be formed in the front surface of the backboard 14, but in this embodiment, the backboard 14 of The front surface can be planar. For this reason, the appearance inside the sheet seen through the net 11 can be further improved.

(Third embodiment)
In the first embodiment, the blown air is blown toward only the front seat occupant. However, in the third embodiment, the air is blown toward the front seat occupant and the rear seat occupant as shown in FIG. The air conditioning area is expanded by blowing air.

  Specifically, an air outlet 16a that communicates with the duct passage 14a is formed in the backboard body 16. That is, by forming the anti-skin member-side air outlet 16a that opens toward the side opposite to the net (skin member) 11, the blown air can be blown toward the rear seat passenger. In addition, you may provide the wind direction guide 18 and the opening-and-closing mechanism 19 which are shown in FIG. 4 in the blower outlet 16a.

(Other embodiments)
In addition, in each said embodiment, although the net | network 11 is used as a sheet | seat skin member, it is not limited to this, Various skin members which have air permeability can be used instead of the net | network 11. FIG.

  Moreover, in each said embodiment, although this invention is applied to the ventilation type sheet | seat air conditioner which ventilates a wind toward the back of a passenger | crew from the back side of the net | network 11, the air | atmosphere of a passenger | crew's back is sucked into the back side of the net | network 11. The present invention may be applied to a suction type seat air conditioner. Specifically, if the fan of the blower 15 is reversely rotated with respect to each of the above embodiments, a suction type seat air conditioner can be obtained.

  Moreover, in each said embodiment, although this invention is applied to the sheet | seat air conditioner which only ventilates with the air blower 15, in order to cool or heat air blowing between the air blower 15 and the blower outlets 17a and 16a. A heat exchanger or a filter for removing dust and pollen in the blown air may be provided.

  Moreover, in each said embodiment, although this invention is applied to the backrest part 10b of the vehicle seat 10, this invention is applicable also to the seat surface part 10a and the headrest 10c of the vehicle seat 10. FIG.

  In each of the above embodiments, the example in which the present invention is applied to a vehicle seat has been described. However, the present invention is not limited to this and can be applied to various seats.
