DESCRIPTION OF THE PREFERRED EMBODIMENTS Specific embodiments of the present invention will be described with reference to the drawings.

The present embodiment is a seat support kit including a seat cover capable of holding the seat support device 3 and a seat support device 3 maintaining a shape conforming to the seating shape of the occupant. It is applied to

The seat cover will be described.

In this embodiment, a seat support holder 4 capable of holding a seat support 3 is provided on a back cover 5 of a seat cover 2 to be covered and mounted on a seat 1.

Therefore, if the seat cover is covered with the seat 1, the seat support 3 can be held on the backrest 11 of the seat 1 by the seat cover alone. It is possible to hold the seat support 3 on the backrest portion 11 without necessity.

The seat support holding section 4 is provided with a storage section 6 capable of removably storing the seat support 3.

The storage portion 6 has a bag-shaped portion separated from the backrest cover portion 5 at the front side of the backrest cover portion 5 in the structure of the backrest cover portion 5 of the existing seat cover which is covered and mounted on the backrest portion 11 of the seat 1. It is formed and configured.

As shown in FIG. 2, the storage portion 6 has a configuration in which the side of the backrest cover 5 is opened, and a seat support member is provided in the bag-shaped storage portion 6 from the side of the backrest cover 5. When the seat support 3 is inserted, the whole of the seat support 3 is completely wrapped and concealed and stored.

Therefore, the seat support 3 can be easily inserted and stored in the bag-shaped storage section 6. Also, this storage section 6
Is a configuration that can be easily designed and realized, and can be provided at low cost with excellent mass productivity.
That is, since the idea is to provide the seat support holding portion 4 using the seat cover, such a simple configuration can be realized.

The opening for taking in and out of the storage section 6 is configured to be openable and closable by opening and closing means 7.

Accordingly, by closing the opening of the storage section 6 in which the seat support device 3 is concealed and stored, the seat support device 3 is closed.
, Which makes it difficult to see the appearance of the seat support device 3 being stored.

The opening and closing means 7 employs an opening and closing structure using a fastener. Since the opening / closing means 7 is constituted by such a simple fastener structure, it is possible to provide a simple design and realize mass production with excellent cost. Further, since this fastener is formed on the side portion of the backrest cover portion 5, it is inconspicuous in appearance and has an extremely good appearance. Although the design of the opening / closing means 7 can be changed as appropriate, it is easier to use the fastener of this embodiment or a simple means such as a Velcro (trade name) to make it easier to manufacture and open / close. Very preferred from the standpoint of appearance.

The expression "can hold the seat support 3" described in claim 1 means that the storage portion 6 is provided to store and fix the seat support 3 as in the present embodiment. For example, a configuration for mounting on a sheet, a configuration for mounting and fixing a mounting portion as a holding portion 4 for a seat support, a configuration for providing and fixing a hook portion, and the like, and further, the seat support device 3 is completely fixed The configuration to be performed is also used in a sense including a configuration that is fixed in a somewhat loose state.

The seat support 3 will be described.

In the present embodiment, a foam 8 impregnated with a curable resin 12 having open air bubbles and being cured by contact with air is covered with a breathable cover 9.

Specifically, the foam 8 is preferably a soft foamed polyurethane or the like from the viewpoint of flexibility and elasticity. The porosity (foaming rate) of the foam 8 is preferably 80 to 98% by volume. If the porosity of the foam 8 is less than 80% by volume, the foam 8 lacks flexibility and the impregnation amount of the curable resin 12 is insufficient.
When the porosity exceeds 98% by volume, not only the stiffness of the entire foam 8 becomes insufficient, but also the amount of the curable resin 12 used becomes too large. More preferable porosity is 90 to 97% by volume.
It is.

The foam 8 has an outer shape previously formed in a desired shape of the seat support device 3 (in the drawing, a square plate shape large enough to support substantially the entire front side of the backrest 11 of the seat 1).

As the curable resin 12, it is preferable to use a type which cures by contact with air. Since air contains water vapor in addition to oxygen, a curable resin 12 in which the curing reaction proceeds by oxygen or water vapor is preferable.
Specifically, an oxygen / moisture curing type such as an acrylic type, a silicone resin type, and a urethane type is preferable. As such a curable resin 12, Cemedine Super X, Cemedine Super XL (manufactured by Cemedine Co., Ltd.) and the like are commercially available. In addition, these commercial products have elasticity even after curing, and are more preferable in sitting comfort.

The weight ratio between the curable resin 12 and the foam 8 is preferably 0.5: 1 to 5: 1.
From 1: 1 to 5: 1 is more preferred. If the weight ratio is less than 0.5: 1, the curable resin 12 will be insufficient, and it will not be possible to cure while maintaining the seated shape. On the other hand, if the weight ratio exceeds 5: 1, the flexibility of the seat support device 3 is lost, and the seat support device 3 becomes too hard.

When the curable resin 12 for impregnation is in a liquid state, the foam 8 can be impregnated as it is.
From the viewpoint of workability, it is preferable to use a solution to reduce the viscosity. As the solvent to be used, a saturated aliphatic hydrocarbon-based organic solvent such as hexane, isohexane, heptane, octane, nonane, and decane is preferable from the viewpoint of easy removal and solubility of the curable resin 12. The resin concentration is not particularly limited as long as the curable resin 12 has an appropriate viscosity.

The curable resin 12 may be uniformly impregnated in the entire foam 8 or may be impregnated mainly in the deformed portion. As an impregnation method, the foam 8 is sprayed with a solution of the curable resin 12, or the foam 8 is immersed in the solution of the curable resin 12, and then rubbed sufficiently in a plastic bag to form a foam. Examples of the method include a method of uniformly penetrating the solution of the curable resin 12 and a method of injecting the curable resin 12 into the spots or stripes of the foam 8 using a manifold type nozzle device having a plurality of nozzle portions.

When injecting the curable resin 12 into the foam 8 using a manifold type nozzle, first, a plurality of nozzles of the manifold type nozzle are pressed against the foam 8 to make the foam 8 crushed. Next, the curable resin 12 is supplied at a high pressure and injected into the foam 8 from a plurality of nozzles. When the manifold type nozzle is removed, the foam 8 returns to its original shape, and the curable resin 12 solution is injected only in the vicinity of each nozzle. FIG. 4 shows a spot-like distribution of the impregnated curable resin 12 when each of the nozzles has a dot-like shape.

It is preferable that the time required for the curable resin 12 to be cured to maintain the seating shape is about 30 minutes to about 2 hours. If it is less than 30 minutes, the curing is too fast,
In addition to some progress of curing in the manufacturing process, there are problems that some users have too little room to take a sitting posture. If it is longer than two hours, some users often feel that it is too long. In particular, it is preferable that the setting is made so as to maintain the seating shape in about 30 minutes to one hour.

It is preferable that the breathable cover 9 is formed of a stretchable woven cloth so that wrinkles or the like cannot be caused by deformation of the foam 8. Examples of such a woven cloth for a cover include cotton cloth, knit, and Gore-Tex. It is convenient that the breathable cover 9 is sewn in a bag shape with one side left, and the opening is sealed with a fastener or magic tape. This air permeable cover 9 is used to cure the resin 12
When the sheet support 3 is inserted and stored in the storage section 6 by being covered with the foam 8 impregnated with
12 is prevented from adhering to the storage section 6 and the foam 8 is prevented from being caught and difficult to store, and the user is prevented from touching the curable resin 12.
It becomes very easy to handle.

When the foam 8 is deformed at the time of sheet support molding, the air-permeable cover 9 is
May be formed of a material that exudes. In such a case, the extruded curable resin 12 serves as an adhesive for adhering the sheet support device 3 and the storage section 6, As a result, the seat support device 3
Is positioned and fixed at a predetermined appropriate position. Further, if the breathable cover 9 is made of a material from which the curable resin 12 does not exude, the seat support 3 can be easily taken out of the storage section 6 even after the sheet support is formed.
There is an advantage that the seat support device 3 can be removed and anyone can drive when another person drives without being dedicated to the user. If it is desired to form a complete dedicated seat support, the air permeable cover 9 may not be provided.

In this embodiment, the seat support 3 is sealed with an airtight bag 10.

The airtight bag 10 is used for sealing the foam 8 impregnated with the curable resin 12 and shielding the foam 8 from the air. Especially when using a curable resin 12 that cures when it comes into contact with oxygen or water vapor in the air,
Without high airtightness, curing proceeds during storage. Examples of the material of the airtight bag 10 include polyolefin-based films such as polyethylene, polypropylene, and poly-4-methylpentene-1, and polyester-based films such as polyethylene terephthalate on which aluminum is vapor-deposited, aluminum foil laminated, or the like. Is preferred.

In order to minimize the air remaining in the airtight bag 10, it is preferable to perform vacuuming or purging with nitrogen gas. Even in the case of replacement with nitrogen gas, it is preferable to sufficiently reduce the pressure so that the airtight bag 10 does not burst due to a rise in the temperature inside the airtight bag 10. In addition, if the container is hermetically sealed in a state of being evacuated, the package can be reduced in size, and the transportation cost and the storage cost can be reduced.

Since it is difficult to completely remove the residual air or the organic solvent even by vacuuming or replacing with nitrogen gas, a desiccant, an adsorbent, an oxygen scavenger and the like are put in the airtight bag 10. Is preferred. In addition, a deodorant, a preservative, a fungicide, an aromatic, and the like may be contained in the curable resin 12 or may be put in the airtight bag 10.

The sealing in the airtight bag 10 will be described. First, after the impregnation of the curable resin 12 is completed, the organic solvent is removed by appropriately reducing the pressure. If the organic solvent remains, it emits a peculiar smell when the airtight bag 10 is opened. After removing the organic solvent, the foam 8 is covered with a gas permeable cover 9 and placed in an airtight bag 10 together with a desiccant, an adsorbent, an oxygen scavenger and the like. Next, the airtight bag 10 is sealed by heat sealing or the like by reducing the pressure or replacing with nitrogen gas. In addition, as described above, if the package is sealed only by the reduced pressure, the package can be reduced.

Next, the method of use will be described.

The seat 1 is covered with the seat cover 2.

The airtight bag 10 is opened, and the seat support 3 in the state shown in FIG.
Set to.

Since the seat support 3 is flexible at first, when it is seated on the seat 1, the seat support 3 is deformed according to the occupant's body shape and sitting posture. At this time, oxygen and water vapor in the air come into contact with the curable resin 12 in the foam 8 through the air permeable cover 9, so that the curable resin 12 in the foam 8 starts to cure while sitting down, and It cures in about two to two hours to maintain the seated shape. At this stage, a seat support that retains a desired seating shape can be obtained even if the seat support is separated from the seat 1, but the user may sit still until the curing is completed.

In this way, for example, before the operation,
If the seat support device 3 is stored in the storage portion 6 after opening the seat 10 and the drive goes to a drive or the like, the seat support can be easily formed during operation.

Therefore, in this embodiment, simply
"Attach a seat cover to seat 1.", "Airtight bag
10 is opened, and the seat support 3 is stored in the storage section 6. ”And“ Sit on the seat 1 ”, it is possible to easily and easily form a seat support that retains the seating shape of the individual occupant, and the operability is excellent. .

Therefore, this method of use allows the user to easily form a seat support that retains the user's personal sitting shape by his / her own work. It becomes a kit for seat support.

The seat support 3 can be held and fixed in an invisible state simply by inserting the seat support 3 from the side of the back cover 5 into the storage section 6 and closing the fastener.

The storage section 6 can also be used for storing, for example, a warmer, and is very practical.

FIGS. 9 to 11 show another example of this embodiment.

FIG. 9 shows a case where the seat support 3 and the back cover 5 are sealed with an airtight bag 10 unlike the above-described embodiment in which only the seat support 3 is sealed. In this case, after opening the airtight bag 10, a sheet support is formed by the same forming operation as described above.

FIG. 10 shows a state in which the seat support 3 is held in the seat support holder 4 of the back cover 5 in advance.
The back cover 5 holding the seat support 3
Is sealed with an airtight bag 10. Further, in this configuration, since the user does not touch the seat support 3, the seat support 3 is not covered with the breathable cover 9. The air-permeable cover 9 may be covered. However, when the seat support 3 is deformed in accordance with the seating shape at the time of forming the seat support, the curable resin 12 directly adheres to the storage section 6 in this state. Since it is cured, the sheet support 3 is adhered to the storage section 6 and is positioned and fixed at an appropriate position. In addition, in the case of this configuration, since the work of inserting the sheet support member 3 into the seat support holding portion 4 at the time of forming the seat support can be omitted, the handling becomes easier accordingly. Although the drawings show the case where the opening / closing means 7 (fastener) is provided, the opening / closing means 7 may be omitted in such a configuration.

FIG. 11 shows another example of the storage section 6.
The drawing shows a state in which the backrest cover portion 5 of the seat cover body 2 is turned upside down, and an upper opening type pocket-shaped storage portion 6 having no opening / closing means 7 is formed on the front side of the backrest cover portion 5 turned upside down. Is the case. In the figure, (a) forms a storage portion 6 on substantially the entire front side surface of the backrest cover portion 5,
(b) is a configuration in which the storage section 6 of (a) is formed into two upper and lower sections so that the seat support 3 can be stored in the upper and lower storage sections 6 respectively. According to this configuration, the backrest cover 5
The seat support device 3 can be easily stored in the storage portion 6 by turning over, and if the backrest cover portion 5 is turned over, the seat support device 3 becomes invisible, so that a good appearance can be obtained. As compared with the above-described embodiment, the cost is reduced and the production is facilitated by the absence of the opening / closing means 7.

In the present embodiment, the seat support holding portion 4 (storage portion 6) is provided on the backrest cover portion 5 of the seat cover body 2 so that the seat support device 3 can be stored and held in the backrest portion 11 of the seat 1. Although the configuration is shown as above, the seat support for the foot support may be formed by providing the seat support holding portion 4 on the seat cover covering the seat 14 of the seat 1.

As for the product form at the time of sale, a seat support kit comprising the seat cover and the seat support device 3 as in the above embodiment and another example of FIGS. The vehicle may be set as an option, and when requested, a seat cover may be attached in advance at the factory, and the seat support device 3 may be stored in the storage unit 6 and delivered to the purchaser when requested. You may do it. Further, in the case of such a delivery to a vehicle dealer, for example, a configuration may be employed in which the seat support device 3 is not allowed to be put in and out of the storage portion 6 and only the opening cut portion of the airtight bag 10 is partially exposed. Opening / closing means 7 as in the embodiment
The user takes out the sheet support device 3 from the storage portion 6 during the sheet support molding, and opens the airtight bag 10 as a configuration in which the sheet support device 3 sealed with the airtight bag 10 is simply stored in the storage portion 6 having Afterwards storage section 6 again
