Description

  The present invention relates to a sheet having an air conditioning function, and more particularly to a structure of a sheet that can increase the degree of freedom of the air conditioning function.

  As shown in FIG. 4, the conventionally known vehicle air-conditioning seat has the entire seating surface of the seat cushion 1 in the pad material 2 of the seat cushion 1 and in the pad material 4 of the seat back 3. A cooling air passage 6 in which a plurality of air outlets 5 are distributed and a cooling air passage 8 in which a plurality of air outlets 7 are distributed over the entire backrest surface of the seat back 3 are formed. The cold air fed to the cold air passages 6 and 8 through 10 and 11 is sent out to the seated person through the breathable sheet skins 12 and 13 from the blowout ports 5 and 7, respectively.

  However, in this case, it is necessary to specially prepare the pad materials 2 and 4 having a completely different structure from the pad material of the sheet that does not have the air conditioning function. In particular, the manufacturing cost of the vehicle seat has been increased as a whole.

  In addition, as a sheet | seat which has an air-conditioning function, the technique shown by the following patent document 1 and the patent document 2 is also known conventionally.

Japanese Patent Laid-Open No. 10-215975 Japanese Patent Laid-Open No. 11-59163

  In the case of Patent Document 1, the air distribution in the seat cushion and the seat back is almost determined by the air supply path in the seat cushion and the shape of the air supply path in the seat back. Is relatively small, and at the same time, it is necessary to install a specific large air supply path in the pad material. Therefore, there is a problem that the manufacturing cost increases, and in the case of Patent Document 2, there is a problem equivalent to the above prior art. It cannot be avoided.

  The present invention is intended to provide a seat that can easily increase the degree of freedom of the air conditioning function.

  For this reason, the air-conditioning seat according to the present invention is provided on the seat cushion base or the seat back cushion base where the seat cushion or the seat back has great elasticity, and on the seated person side of the seat cushion base or the seat back cushion base. An air-conditioning cushion arranged and a skin covering the air-conditioning cushion with air permeability, wherein the air-conditioning cushion is wrapped with a non-breathable fabric material, and the fabric material In addition, an inlet port for conditioned air and a plurality of outlets opened on the seated side are formed.

  That is, the air-conditioning cushion arranged on the seat occupant side (the seating surface side or the back surface side) of the seat cushion base material or the seat back cushion base material having high elasticity is a flexible fabric with a coarse mesh and its surface direction. In addition, air permeability is great in both the direction intersecting with the surface, so-called air-permeable cushion material is wrapped in a substantially non-breathable fabric material, so the air permeability from the inlet formed in the fabric material When air-conditioned air is supplied to a cushioning material, the air-conditioned air flows in the air-permeable cushioning material as appropriate in the direction of the surface, etc., and flows out from a plurality of outlets opened on the seated person side in the fabric material. As a result of being blown out to the seated person through the skin with air permeability, the air conditioning function for the seated person can be achieved, while the distribution, number, shape and size of the outlets in the fabric material By adjusting the like, it is possible to easily control the air conditioning function, it is possible to increase easily the freedom of the air conditioning function.

Examples of the present invention will be described below.
In FIG. 1, a vehicle air-conditioning seat 20 has a breathable property with a seat cushion base material (pad material) 22 having a large seat cushion 21 and an air-conditioning cushion 23 disposed on the seating surface side of the seat cushion base material 22. In addition, it has a skin 24 that covers the air conditioning cushion 23, and the seat back 25 is disposed on the backrest surface side of the seat back cushion base material (pad material) 26 having high elasticity and the seat back cushion base material 26. The air conditioning cushion 27 and the skin 28 that covers the air conditioning cushion 27 with air permeability are provided.

  As shown in FIG. 2, the air-conditioning cushions 23 and 27 are made of a breathable cushion material, for example, a double raschel fabric 31 obtained by center-cutting a double raschel structure with a substantially non-breathable fabric material 30. As shown in the case of the air-conditioning cushion 23 in FIG. 3, the skins 24 and 28 where the seated person comes into contact with the seating surface side and the backrest surface side of the fabric material 30, respectively. A plurality of air outlets 32 are opened in contact with each other, and the air outlets 32 are formed in an appropriate number, shape and size in an appropriate distribution state, and on the opposite side of the fabric material 30 from the seated person side. A single inlet 33 is formed near the center, and each inlet 33 is provided in the seat cushion base material 22 and the seat back cushion base material 26, respectively. And it is connected to the cold air source 35 by the air passage 34 which is.

  Accordingly, the cold air fed from the cold air source 35 through the air passage 34 to the double raschel fabrics 31 through the inlets 33 of the air conditioning cushions 23 and 27 is appropriately transmitted through the double raschel fabrics 31 in any direction such as the surface direction. It flows in a direction, flows out from the outlet 32 of the dough material 30, and is blown out to the seated person side through the part where the seated person of the skins 24 and 28 having air permeability contact each other. Thus, the air conditioning function for the seated person's back and under the knee can be achieved. At this time, the air outlet 32 is blown out from the skins 24 and 28 by appropriately selecting the distribution, number, shape, size, and the like of the outlet 32. The location, air volume, etc. can be adjusted, and the distribution, number, shape, size, etc. of the outlets 32 can be set very freely and easily. Becomes able to, there is a feature that is possible to increase easily the freedom of the air conditioning function.

  In addition, since the air conditioning cushions 23 and 27 are covered with the skins 24 and 28, respectively, the appearance of the seat 20 is the same as that of the conventional seat and is not worn out by the seated person, so that the durability is surely improved. In addition, the cool air that has flowed out from the air outlet 32 of the air conditioning cushions 23 and 27 is blown out to the seated person through the skins 24 and 28, respectively, so that it is not blown directly to the seated person. It can be made to have a gentle air conditioning.

  Furthermore, in the air-conditioning seat 20, it is necessary to form a cold air outlet and a cold air passage in the seat cushion base material 22 of the seat cushion 21 and in the seat back cushion base material 26 of the seat back 25 as in the past. Since there are no air conditioning cushions 23 and 27, the seat without air conditioning function can be obtained by simply removing the air conditioning cushions 23 and 27. That is, the relatively large seat cushion base material 22 and the seat back cushion base material 26 can be used as the air conditioning seat. 20 and a seat that does not require an air-conditioning function can be easily shared. Therefore, there is a practical advantage that the manufacturing cost of a vehicle seat having a different seat shape and seat layout can be reduced as a whole.

  When the air conditioning cushions 23 and 27 are removed from the air conditioning seat 20, a slight gap is likely to be generated between the seat cushion base material 22 and the skin 24 or between the seat back cushion base material 26 and the skin 28. However, since it can be easily absorbed by the thickness of the skins 24 and 28, or when the absorption is not complete, a plate-like cushion material having a thickness substantially equal to the air conditioning cushions 23 and 27, respectively, is used. If it is replaced with 27, the above-mentioned sharing can be easily achieved.

  Moreover, in the said Example, although the inlet 33 is formed in the center part vicinity on the opposite side to the seated person side of the fabric material 30, since the air permeability in the surface direction of the double Russell fabric 31 is large, a blower outlet The position of the inlet 33 is appropriately changed in consideration of the distribution, number, shape, size, etc. of 32, or, if necessary, the fabric material 30 at the periphery of the air conditioning cushions 23, 27 and the inlet 33. Even if an alternative inlet is provided, the same effects as the above-described embodiments can be exhibited, and the cold air in each of the above-described embodiments can be replaced with warm air or room temperature air. Needless to say, as a cushioning material, in addition to the double raschel fabric, a fabric that has been subjected to double raschel knitting, a non-woven fabric, or a breathable material such as a fiber sheet can be used. .
