A spacer member 14 which allows air to circulate is arranged inside the bag body to specify the inside as an air flow path. While the lower part member 12-2 of the bag body 12 is formed of a non-air-permeable material, the upper member 12-2 is formed of an air-permeable material. While limiting an air-permeable area in the upper member by applying on the upper member the pattern printing 30 in which a non-air-permeable coating material is coated, the pattern printing is performed as dot printing. The ventilation amount in the upper member can be adjusted by section in response to nonuniformity in dot density.

Description

  The present invention relates to a ventilation insert that is disposed under the skin of a vehicle seat or the like and forms a ventilation layer in the seat.

  Known as an automobile sheet is an air-conditioning sheet that discharges hot air or cold air supplied from the outside of the sheet from the inside of the sheet to the surface of the sheet, or a ventilation sheet that distributes heat, moisture, etc. of the surface of the sheet inside the sheet Yes. And as this kind of sheet, a configuration is known in which a ventilation insert is arranged on the seat pad under the surface of the sheet, and the inside of this ventilation insert is secured as an air flow path, that is, a ventilation layer (for example, , Japanese translation of PCT publication No. 2004-520889).

  This type of ventilation insert secures the inside of the bag as an air flow path (venting layer) by providing a spacer member through which air can flow in the bag made of a non-breathable material (cloth). Yes. Usually, a plurality of vent holes are provided in the upper member of the bag body, and a vent opening connected to a blower or a duct defined in a part of the bag body is communicated with the vent hole via the spacer member. Accordingly, it is possible to supply hot air and cold air to the sheet surface, or to distribute heat, moisture and the like on the sheet surface.

JP-T-2004-520889

  As disclosed in JP-T-2004-520889, in a known configuration, by providing a plurality of ventilation holes in the upper member of the bag body, the inside of the bag body, that is, the bag body and the seat surface (sitting surface) Air circulation (ventilation) between them is obtained. In this way, by providing a plurality of holes in the upper member of the bag body, the air permeable region can be clearly limited, and by changing the size and interval of the plurality of holes, the air flow amount according to the site on the sheet surface Can be selectively obtained as appropriate.

  However, because of the property of drilling a plurality of ventilation holes in the fabric, a predetermined interval is required between the ventilation holes, so the ventilation performance depends on the difference in the presence or absence of ventilation between the parts with and without the ventilation holes. That is, there is a risk of causing temperature unevenness on the sheet surface.

  In addition, if the ventilation amount is adjusted by the size of the ventilation hole provided in the bag upper member, fine adjustment of the ventilation amount is not easy, and fine adjustment of the ventilation amount may not be performed.

  An object of the present invention is to provide a ventilation insert that can obtain uniform ventilation performance and can easily finely adjust the ventilation amount.

  For the above purpose, according to the ventilation insert of the present invention according to claim 1, the lower member of the bag body is made of a non-breathable material, whereas the upper member of the bag body is made of a breathable material, By performing pattern printing by applying non-breathable paint on the upper member, the air permeable area on the upper member is limited, and this pattern printing is dot printing. Can be adjusted for each part.

  According to the vent insert of the present invention according to claim 2, the lower member of the bag body is made of a non-breathable material, whereas the breathable material is joined on a plane on at least a part of the bag. By arranging a breathable material having a required ventilation rate at a corresponding location in the upper member as the upper member of the body, the ventilation rate in the upper member can be adjusted for each part.

  Furthermore, according to the ventilation insert of the present invention according to claim 3, the bag lower member is made of a non-breathable material, whereas at least a part of the bag body is layered with a breathable material step by step. By using the upper member of the body and changing the overlapping amount of the breathable material according to the required amount of ventilation, the amount of ventilation in the upper member can be adjusted for each part.

  In the present invention according to claim 1, since ventilation through the breathable material is obtained, uniform ventilation performance can be easily ensured in the upper member of the bag body. In addition, it is possible to limit the breathable area by pattern printing by applying non-breathable paint, and the printing is dot printing, and the air flow rate can be adjusted by the density of the dot density, so fine fine adjustment of the air flow rate is easy It becomes possible.

  Further, in the present invention according to claim 2, since the ventilation performance of the upper member is ensured by joining the materials having different breathability on the plane, the uniform ventilation performance can be easily achieved in the upper member of the bag body. Further, by arranging the material of the upper member according to the required air flow rate, fine fine adjustment of the air flow rate according to the part can be easily performed.

  Furthermore, in the present invention according to claim 3, since the ventilation amount in the upper member can be adjusted by layering the breathable materials in stages, uniform ventilation performance is easily ensured in the upper member of the bag body. In addition, it is possible to easily finely adjust the ventilation amount according to the site.

The schematic perspective view of the partial fracture | rupture of the ventilation insert of this invention is shown. (A) and (B) show a schematic partial exploded perspective view and a schematic partial cross-sectional view, respectively, of the ventilation insert. 1 is a schematic longitudinal sectional view of a vehicle seat with a ventilation insert incorporated therein. The schematic perspective view of the insert for ventilation | gas_flowing which concerns on an example of a pattern printing shape is shown. The schematic sectional drawing of the insert for ventilation | gas_flowing which shows the modification of this invention is shown. The schematic sectional drawing of the insert for ventilation | gas_flowing which shows another modification of this invention is shown.

  While the lower member of the bag body is made of a non-breathable material, the upper member of the bag body is made of a breathable material, and the area that can be vented is limited by pattern printing by applying non-breathable paint. Printing is used, and the air flow rate in the upper member can be adjusted for each part by the density of the dot density.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a schematic perspective view of the ventilation insert of the present invention, and FIGS. 2A and 2B are a schematic exploded perspective view and a schematic longitudinal sectional view of the ventilation insert, respectively. As shown in these figures, the ventilation insert 10 according to the present invention is provided with a spacer member 14 that allows air to flow in the bag body 12, thereby ensuring that the bag body has a ventilation layer that allows air to flow. Yes.

  FIG. 3 is a schematic longitudinal sectional view of a vehicle seat in which a ventilation insert is incorporated. As shown in FIG. 3, this type of ventilation insert 10 includes a seat cushion 18 of a vehicle seat 16 and a seat back 20. It can be arranged in any case, and is usually disposed on the back surface (subcutaneous surface) of the epidermis 24 covering the seat surface on the upper surface (or front surface) of the seat pad 22 which is a cushion body. The skin 24 of the seat cushion and seat back is made of a breathable material that can ensure ventilation between the front and back surfaces of the skin.

  As shown in FIGS. 1, 2 </ b> A and 2 </ b> B, the bag body 12 of the ventilation insert 10 closes and connects the peripheral edges of the upper member 12-1 and the lower member 12-2 by stitching, bonding, or the like. Thus, a bag-like shape is formed, and a part of the bag is defined as a vent opening 26 that communicates with a temperature-controlled air supply device, blower, or duct. In FIG. 1, the blower 28 is illustrated as an example, and the blower is embodied as being attached to the ventilation opening 26.

  Then, by arranging a breathable spacer member 14 between the upper member 12-1 and the lower member 12-2 forming the bag body 12, air can flow between the upper member and the lower member, that is, into the bag body. A ventilation layer is secured. In addition, as this spacer member 14, the three-dimensional fiber structure etc. which combined the fiber raw material etc. which can ensure the air flow path without being crushed even under a seated person's load can be utilized.

By the way, in this kind of ventilation insert 10, since it is requested | required that the upper member 12-1 should have air permeability, in this invention, the lower member of a bag body is formed from a non-air-permeable material. On the other hand, at least a part of the upper member of the bag body is formed from a breathable material.
However, if the entire surface of the upper member 12-1 is simply made of a breathable material, it is not possible to limit the area of the upper member that can be vented and to adjust the amount of ventilation for each part. FIG. 4 shows a schematic perspective view of a ventilation insert according to an example of a pattern printing shape. As shown in FIG. 4, in this embodiment, the pattern printing 30 is performed by applying a non-breathable paint to the upper member 12-1. As a result of this, the air permeable region in the upper member is limited, and this pattern printing is dot printing, and the air flow amount in the upper member can be adjusted for each part by the density of the dot density.

  For example, when pattern printing having a shape imitating a pressure distribution diagram at the time of sitting on the seating surface of the seat cushion 18 is illustrated, the outer peripheral edge 30-1 of the upper member 12-1 is non-breathable by, for example, solid-coating By defining it as a ventilation area and making the inner area 30-2 a dot printing area, it is set as a breathable area where ventilation is possible. In the dot printing area (inner area) 30-2, the air flow rate can be changed by changing the dot density. In other words, by making the dot density rough, the application area of the non-breathable paint decreases, so a large amount of air flow can be secured, and by increasing the dot density, the application area of the non-breathable paint increases. Therefore, the amount of ventilation can be suppressed.

  Thus, according to the configuration in this embodiment, the non-breathing region is formed by applying the non-breathable coating material to the upper member 12-1 made of the breathable material. That is, since the portion where the non-breathable coating is not applied is limited as a breathable region, it is possible to easily limit the breathable region in the upper member 12-1 made of a breathable material. And since the breathable area | region formed in this way is a breathable raw material itself, it cannot be overemphasized that a uniform ventilation | gas_flowing amount is obtained.

  Further, in this embodiment, the pattern printing applied to the upper member 12-1 is dot printing, and the air flow rate in the upper member can be adjusted for each part by the density of the dot density. This makes it possible to easily adjust the fine air flow, that is, fine adjustment of the air flow, which cannot be obtained by installation.

  In this embodiment, a shape imitating a pressure distribution diagram at the time of sitting is embodied as the pattern printing shape, but it is needless to say that the pattern printing shape is not limited to this.

5 and 6 are schematic sectional views of a ventilation insert showing a modification of the present invention, respectively.
In the above embodiment, the amount of air flow in the upper member 12-1 is adjusted by applying a non-breathable paint. However, the present invention is not limited to this. For example, the lower member 12-2 of the bag body 110 is made of a non-breathable material as in another embodiment shown in FIG. By connecting the materials 112-1a and 112-1b on a plane to form an upper member 112-1 of the bag body, and arranging a breathable material having a required ventilation amount at a corresponding location in the upper member, The ventilation amount in the upper member may be adjustable for each part.

  In addition, as in another embodiment shown in FIG. 6, the lower member 12-2 of the bag body 210 is made of a non-breathable material, whereas at least part of the breathable materials 212-1a, 212- 1b and 212-1c are overlapped step by step to form the upper member 212-1 of the bag body, and the amount of ventilation in the upper member is changed by changing the amount of breathable material according to the required amount of ventilation. It may be adjustable for each part.

  In any of these embodiments, the breathable materials constituting the upper member are connected by, for example, sewing.

  In the embodiment shown in FIG. 5, since the ventilation performance of the upper member 112-1 is secured by connecting the materials 112-1a and 112-1b having different ventilation characteristics on a plane, a uniform ventilation performance is obtained. The upper member of the bag body can be easily secured, and by arranging the material of the upper member in accordance with the required amount of ventilation, fine fine adjustment of the amount of ventilation according to the site can be easily performed.

Further, in the embodiment shown in FIG. 6, the ventilation amount in the upper member 212-1 can be adjusted by overlapping the breathable materials 212-1a, 212-1b, and 212-1c in stages, Homogeneous ventilation performance can be easily ensured in the upper member of the bag body 212, and fine fine adjustment of the ventilation amount according to the part can be easily performed.
In addition, the air flow rate of the air permeable materials 212-1a, 212-1b, and 212-1c in this embodiment may be the same or different.

  The above-described embodiments are for explaining the present invention, and are not intended to limit the present invention. All modifications, alterations and the like within the technical scope of the present invention are included in the present invention. Needless to say.

  Although the present invention is excellent in application to air conditioning sheets and ventilation sheets for automobiles and the like, it is not limited to this, for example, other vehicle seats such as trains, airplanes, ships, etc., and household seats and various facilities You may apply to a sheet.
