The present invention relates to, for example, a ventilation device mounted on a seat of a vehicle such as an automobile, and in particular, by devising a configuration of a ventilation path, it is possible to obtain a desired value even if a driver or the like repeats sitting and leaving. The present invention relates to an inexpensive one that can stably secure a ventilation volume, does not impair sitting comfort, and is inexpensive.

Background art

[0002] For example, when a person sits in a seat of an automobile or the like for a long period of time particularly under conditions of high ambient temperature and humidity, the surface of the seat and a human body contact portion may be "humid" or "sticky". Occurs. Since this "humidity" and "stickiness" cause a loss of comfort of the occupant, various countermeasures against such a problem have been conventionally studied.

[0003] For example, in Patent Document 1, a ventilation device that blows air with the internal force of a vehicle seat also directed toward the surface is provided, thereby eliminating "humidity" and "stickiness". Has been proposed.

FIG. 23 is an exploded perspective view showing an example of a vehicle seat disclosed in Patent Document 1. In the vehicle seat shown in FIG. 23, an elastically deformable rubber material is provided in the recess 110 of the seat pad 107 in which a recess 110 is formed on the surface on the occupant contact side, with a seat skin 109 having air permeability. A blower tube 111 as a blower path forming means is provided, and air blown from an air conditioner unit 112 as a blower moves in the blower tube 111 and is formed on the occupant contact side of the blower tube 111. Air is blown to the occupant through a seat skin 109 from a through hole 114 serving as an air passing portion.

[0005] Another example of this type of ventilation device is disclosed in Patent Document 2, for example. FIG. 24 is a perspective view showing the configuration of the ventilation device disclosed in Patent Document 2 described above. In FIG. 24, reference numeral 115 denotes a branch joint connected to a blower (not shown) (for example, an air pump). The branch joint 115 is arranged in parallel at a predetermined interval. An air passage group 118 including a plurality of flexible tubes 116 is connected. Then, a single air outlet 117 is formed in the flexible tube 116 constituting the ventilation path group 118 so as to be shifted from each other.

Disclosure of the invention

Problems to be solved by the invention

[0010] However, the conventional configuration has the following problems.

First, in the conventional example shown in Patent Document 1, it is necessary to form in advance a concave portion 110 having a complicated shape in the sheet pad 107 in order to obtain an air blowing amount and an air blowing amount equal to a required area. Further, it is necessary to prepare a blower tube 111 having a complicated shape that fits in the concave portion 110 without any gap, so that there is a problem that the cost is greatly increased.

[0011] Further, the through-hole 114 provided in the blower tube 111 does not necessarily face the seat skin 109 side, the amount of air blown out from the seat skin 109 decreases, but by repeating seating and seating, There is a possibility that the direction of the ventilation hole 114 may be shifted in a direction in which the sheet surface force is different from the direction in which the ventilation tube 111 arranged in the concave portion 110 of the sheet pad 107 is twisted. In such a case, the amount of air blown out from the seat skin 109 is greatly reduced, and eventually the seated person's feeling of suitability for water is impaired.

[0012] In order to solve this problem, for example, it is conceivable to adhesively fix the concave portion 110 formed in the sheet pad 107 and the blower tube 111. Since it is necessary to perform positioning so that it is on the side, the work becomes very complicated and the workability is greatly reduced. Also, in this case, the adhesive used for bonding and fixing the recess 110 formed in the sheet pad 107 and the blower tube 111 penetrates into the sheet pad 107, so that a part of the sheet pad 107 becomes flexible. As a result, the texture becomes hard and the texture becomes hard, which causes a problem that a seated person's sense of suitability is deteriorated.

On the other hand, in the conventional example shown in Patent Document 2, it is not necessary to previously form a complicated concave portion in the sheet pad, and it is necessary to prepare a tube that matches the shape of the concave portion of the sheet pad. Therefore, it is considered that the cost is more advantageous than the first conventional example. By simply arranging a plurality of flexible tubes 116 in parallel with each other while suppressing the sharing of the seating load, it is unavoidable that each of the flexible tubes 116 collapses depending on the magnitude of the load. In particular, when the diameter of the flexible tube 116 is increased in order to increase the ventilation volume, or when the seat pad 107 is softened to improve the comfort, the flexible tube 116 is used. There is a problem that the crushing becomes remarkable. This is because a predetermined gap is formed between the plurality of flexible tubes 116, so that when a load is also applied to the upper side force of the flexible tube 116, the flexible tube 116 is It was caused by spreading to the area.

[0014] Further, in this conventional example, when seating and unseating are repeated, each flexible tube 116 moves, and the flexible tubes 116 overlap with each other, or the flexible tube 116 is twisted. However, there is a possibility that the outlet 117 faces in a direction different from the seat skin side. In this case, it is not possible to secure a sufficient amount of blown air, and the arrangement of the flexible tubes 116 becomes uneven, so that a sense of discomfort when seated becomes remarkable, and the comfort of the seated person is impaired. The problem that it ends up occurs.

[0015] The present invention has been made based on such a point, and an object of the present invention is to stably secure a desired airflow amount even if a seated person repeatedly sits and leaves. When you can Another object of the present invention is to provide an inexpensive ventilation device that does not impair sitting comfort.

Therefore, it is possible to stably secure a required amount of ventilation according to the intended use, and it does not impair sitting comfort. In addition, since it is not necessary to provide a concave portion in the sheet pad in advance and it is not necessary to fix the sheet pad using an adhesive or the like, the manufacturing process can be greatly reduced, and the cost is reduced. A wind device can be provided.

BEST MODE FOR CARRYING OUT THE INVENTION

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

This embodiment shows an example in which the present invention is applied to a vehicle seat such as an automobile.

The ventilation device 1 according to the present embodiment has a configuration as shown in FIG. First, there is an air supply source 2 that also serves as a fan.This air supply source 2 is made of a thermoplastic thermoplastic elastomer, and 70 tubes 4 with an inner diameter of 3πιπιφ and an outer diameter of 4mmφ are integrated in parallel to form a sheet. The formed ventilation path 3 is connected. Here, the ventilation passage 3 is inserted into the outlet of the air supply source 2 in a state where one end of the tube 4 that is parallel-integrated is divided and overlapped so that it can be inserted into the outlet of the air supply source 2. It is fixed. On the upper surface side (seat skin side) of the plurality of tubes 4 constituting the ventilation path 3, three straight slit-shaped outlets 5 having a width of 10 mm are formed at 60 mm intervals, and are connected to the air supply source 2. The other end is closed.

[0019] With the ventilation device 1 having such a configuration, even if a load is applied to the tube 4 from above and the tube 4 is flattened, the horizontal tubes 4 are laid out, so that the tube 4 is flattened. There is no escape area for the part that has been removed, and deformation beyond a certain level is restricted, so that even if the load assumed in actual use is applied, it is possible to secure a desired ventilation volume that will not be completely collapsed

[0020] Here, in the case where the tubes 4 are not arranged in parallel, the ventilation volume at the time of sitting decreases to a maximum of 0.6% as compared with the case where the tubes 4 are not seated. It has been confirmed by experiments that when the tubes 4 are parallel-integrated as in the embodiment, the reduction is limited to a maximum of 47%.

[0021] In addition to the method shown in Fig. 1 as a method of connecting the air supply source 2 and the air passage 3, for example, as shown in Fig. 2, the air supply source 2 and the air passage 3 are connected by a nozzle. Connection via 6 is conceivable. This direction has the advantage that the amount of air flow through both tubes 4 at the ends is substantially equal.

The air supply source 2 and the nozzle 6 are not limited to being directly connected. In order to increase the efficiency, it is also possible to connect the blowing source 2 and the nozzle 6 via a duct having an arbitrary cross-sectional shape.

[0022] In the case where the air supply source 2 and the ventilation passage 3 are connected via the nozzle 6, if the cross-sectional shape of the tube 4 is circular, as shown in FIG. It is preferable to connect the tubes 4 in two rows. Thereby, the gap between the nozzle 6 and the tube 4 at the connection portion can be reduced, so that the blowing loss can be reduced. Comparing the air flow rate when one row of tubes 4 is used and two rows of tubes 4, it was 206.7 L / min for one row, but 232.8 LZmin for two rows. It is confirmed that the two rows have a larger airflow and a smaller airflow loss.

When connecting the tubes 4 in two rows, as shown in FIG. 4, at the end of the tube 4 on the nozzle side, the joint between the upper row and the lower row is cut off, so-called “ It is also conceivable to make it “mortar-shaped” (the part cut off in FIG. 4 is indicated by reference numeral 4a.) ₀ This allows the wind to move toward the center of the integrated tube 4, and the nozzle 6 and the tube Since it is difficult to get out of the gap with 4, the blowing loss can be reduced.

[0024] The material of the tube 4 is not particularly limited. In addition to the above-mentioned olefin thermoplastic elastomer, for example, olefin resin, silicone rubber, vinyl chloride resin, polyvinylidene fluoride (PVDF), Various materials such as ethylene-tetrafluoroethylene copolymer (ETFE) and various elastomers can be used.

[0025] The diameter and thickness of the tube 4 are not particularly limited, either, and may be appropriately set in accordance with the characteristics such as flexibility, crush resistance, and air flow. Also, the length and number of tubes may be appropriately set according to the desired blowing position and usage form.

[0026] The cross-sectional shape of the tube 4 is not particularly limited. For example, if the tube 4 has a square shape with multiple holes as shown in Fig. 5, the bonding strength between the tubes 4 is similar to that of the square tube 4 which has a nearly linear bonding surface in the case of a tube 4 having a circular cross section. In this case, since the bonding surface is wide, there is an advantage that a higher bonding strength can be obtained. Furthermore, in the case of the square tube 4, the same ventilation volume can be obtained even if the cross section is lower than in the case of a circular cross section. There is an advantage that comfort is not impaired. Another advantage is that the number of pieces required for a given area can be reduced, thereby reducing costs. The

On the other hand, if the cross-sectional shape of the tube 4 is circular, there is an advantage that the tube 4 is less likely to be crushed even when a load more than expected in actual use is applied, as compared with the case where the cross-sectional shape is square. Further, when the ventilation device is incorporated in the curved surface portion, there is an advantage that the tube 4 is easier to be bent when the cross-sectional shape of the tube 4 is circular than in the case where the cross-sectional shape is quadrangular. In short, the cross-sectional shape may be appropriately selected according to the use state.

[0028] The position of the outlet 5 may be different for each tube 4 or may be formed in a straight line. However, in Fig. 1, a straight slit-shaped outlet 5 is formed from the viewpoint of mass productivity. are doing. The size of the outlet 5 is not particularly limited.For example, when a tube 4 having an inner diameter of 3πιπιφ and an outer diameter of 4mmφ is used to form a straight slit-shaped outlet 5, the width of the outlet 5 is 15 mm. It is preferable that the air flow be of such a degree that a sufficient amount of ventilation can be obtained and that it is difficult to collapse when a load is applied. In addition, the position of the outlet 5 may be formed at a plurality of locations which may be arbitrarily formed according to the intended use.However, when formed at a plurality of locations, if the distance between them is 50 mm or more, the load may be reduced. Even if hung, it is hard to collapse.

Further, in FIG. 1, a force closing the end on the side not connected to the air supply source 2 is connected to the air supply source 2, and some or all of the end on the side is not closed. It is also conceivable that the air outlet is opened at a location where it functions as an outlet. When the end is an opening, as shown in FIG. 6, the upper part of the end may be cut out so that the wind blows upward. The point is that the outlet 5 may be formed at an arbitrary position of the tube 4 so as to obtain a required amount of ventilation according to the intended use.

In the present embodiment, a required number of tubes 4 are prepared in advance by a known extrusion molding method, and a plurality of tubes 4 are arranged in parallel. The tube 4 is placed in a frame slightly narrower than the total width of the tube 4, a metal plate is placed on the frame so as to cover the entire tube 4, and the tube 4 is heated by applying a predetermined load to soften the tube 4. The two were bonded together. The heating condition was a profile of about 1 hour from room temperature to 200 ° C, and the required adhesive strength was obtained.

[0031] In the present invention, the method for forming a plurality of tubes in parallel and integrally is not limited to the method of bonding and bonding the tubes by applying pressure and heat as described above. For example, as another method, it is conceivable to arrange a plurality of preformed tubes in parallel and then bond the adjacent tubes to each other using an adhesive or the like. In this method, for example, when the material of the tube is silicone rubber, a thermosetting silicone adhesive is suitable.

[0032] As another method, a method in which a plurality of preformed tubes are arranged in parallel and then a laser beam is applied to a contact surface of an adjacent tube to fuse and integrate the tubes together is also considered. Can be In this case, it is possible to use a tube material such as polyvinylidene fluoride (PVDF) or ethylene-tetrafluoroethylene copolymer (ETFE) whose melting point is 200 ° C or more. .

[0033] Another method is to knit a plurality of tubes into a blind shape using a thermoplastic resin knitting yarn or a yarn in which various fibers are coated with a thermoplastic resin, and then heating. A method is also conceivable in which the thermoplastic resin of the knitting yarn and the tube are bonded together to form a sheet in which the spacing between adjacent tubes is maintained.

As another method, a belt-shaped tube having a predetermined width is formed into a sheet by a conventionally known co-extrusion molding method, or a resin film is formed from a conventionally known hot press. It is also conceivable to form the sheet into a sheet with multiple holes in parallel by the less forming method or the welder method.

[0035] A method of directly manufacturing a sheet-like molded product having a plurality of parallel holes by a known injection molding method is also conceivable.

[0036] A method is also conceivable in which tubes are arranged in parallel on a sheet of resin, elastomer, or the like, and the sheet and the tube are integrated. As a specific example, using the same material as the tube (in the case of the present embodiment, an olefin thermoplastic elastomer), a method of integrating the tube and the sheet by heat fusion, and bonding to the surface Using a sheet with layers

And a method of integrating the tube and the sheet with the adhesive layer.

It should be noted that, in the above description, not only the force described as a sheet but also a cloth-like one or a film-like one may be used.

FIG. 7 shows an example of a state in which the ventilation device according to the present embodiment is installed in a vehicle seat such as an automobile. In FIG. 7, first, a sheet pad without a concave portion is formed. A tube 4 is arranged in parallel between the seat skin 9 and the seat skin 9, a ventilation passage 3 formed in a sheet shape is installed, and the tube 4 is connected to an air supply source 2 installed under the seat. Here, the air supply source 2 may be, for example, a built-in Peltier element capable of generating hot air or cold air, or an air conditioner such as an air conditioner, in addition to a normal fan. good. In such a case, by passing cool air through the tube 4, the effect of removing stuffiness and stickiness due to sweat or the like of the seated person is further enhanced, and comfort can be further improved.

[0038] In addition, when the ventilating device is inserted into the ventilator, for example, as shown in Fig. 8, if the outlet 5 is formed in a curved surface portion such as a portion located on the back of the knee, it is formed in a flat portion. Since a larger air volume can be obtained than at the outlet, comfort can be further improved.

Further, as shown in FIG. 9, for example, a conventionally known seat heater 8 may be provided between the ventilation device according to the present embodiment and the seat skin 9. As the seat heater 8, any conventionally known one can be used. For example, the one shown in Patent Document 3 is particularly preferable because it has good air permeability. By combining with a seat heater in this way, it is possible to have both a function of removing stuffiness and stickiness due to ventilation and a heating function.

Patent Document 3: JP 2003-174952 A

[0041] Further, the comfort of the occupant can be further improved by appropriately controlling the timing and amount of ventilation, the temperature and humidity of hot and cold air in combination with a temperature sensor, a humidity sensor, and the like. A little monster.

Note that the overall configuration of the ventilation device of the present invention is not limited to the above embodiment. For example, as shown in FIG. 10, if the tubes 4 integrated in parallel are connected to the nozzle 6 in a state where the direction of the outlet 5 is reversed and two tubes are stacked, air can be blown in two directions.

Further, as shown in FIG. 11, two tubes 4 arranged in parallel and integrated are connected to the nozzle 6 and the outlet tube 5 of the through-hole is formed in the upper tube 4. Since the wind can pass through the upper tube 4 and flow out to the upper side of the ventilation path, the air volume from the outlet 5 can be increased.

[0043] Further, as shown in Fig. 12, if some of the adjacent tubes 4 are not integrally formed, Ventilation can be performed at a plurality of locations.

Further, as shown in FIG. 13, if a plurality of tubes 4 integrated in parallel with the nozzle 6 are connected, air can be sent to a plurality of locations.

As shown in FIG. 14, a ventilation device may be incorporated on the back side of the seat.

In addition, as shown in FIGS. 15 and 16, when a groove 11 for fixing the seat cover 9 is formed in the seat pad 7 of the seat, the groove 11 should be avoided. It is conceivable that ventilation passages 3 and 3 will be installed.

As shown in FIGS. 17 and 18, in order to install the ventilation paths 3 so as to avoid the groove 11, a through hole 13 is formed in the sheet pad 7, and a ventilation hole is formed therein. Passing through Road 3 is not allowed.

[0048] Further, in Fig. 10, a force showing the ventilation path 3 connected to the nozzle 6 by overlapping two tubes 4 in parallel with each other is shown. A configuration is also conceivable in which it can be installed so that air can be sent to both the seat and the back. That is, one provided in a state of two sheets is installed on the seat surface, and the other is installed on the back surface.

[0049] As a method for integrally arranging a plurality of tubes 4 and a sheet, as shown in Fig. 20, the plurality of tubes 4 may be integrally squeezed by sandwiching the plurality of tubes 4 between two sheets 21 and 23. Conceivable. At this time, notches are formed on the sheets 21 and 23 or the sheets 21 and 23 having good air permeability are formed so as not to block the outlet provided in the tube 4. Can be used.

[0050] As a method for integrally bonding a plurality of tubes 4 and a sheet, as shown in Fig. 21, another plurality of tubes 4 are opened at a predetermined interval in front of the opened plurality of tubes 4. It is conceivable that a plurality of tubes 4 are provided, and a plurality of other tubes 4 are further provided with a predetermined interval in front of the tubes 4, and the tubes 4 are integrally formed by a sheet 25. In this case, the site at the above-mentioned predetermined interval becomes the outlet 5. Therefore, a separate step of forming the outlet is not required.

Further, as shown in FIG. 22, if the duct 27 is a branch type, a plurality of (two in the case shown in FIG. 22) nozzles 6 It is conceivable to connect the air passages 3 and 3 with the air passages 3 and 3. Industrial applicability

[0052] As described above in detail, according to the present invention, even if a seated person repeatedly sits on and leaves, a desired amount of ventilation can be stably ensured, and sitting comfort is not impaired. In addition, an inexpensive ventilation device can be provided. In addition to the use of automobiles, for example, it may be used for vehicle seats such as motorcycles and railway cars, child seats, seats for ships and aircraft, seats for ferris wheel at amusement parks, and for various sports fields. Seats for spectators, seats for viewing in theaters and movie theaters, benches installed in stations, theme parks, outdoor parks, etc., sofas and chairs used in homes and offices, barber chairs, various medical institutions, etc. Application to medical chairs and the like that are being used is also conceivable. Further, it can be widely applied not only to seats but also to fields requiring a flexible feel, such as beds, futons, pillows, strollers, toilet seat covers, and clothing.
