BEST MODE FOR CARRYING OUT THE INVENTION A preferred embodiment of the present invention (how to carry out the invention) will be briefly described with reference to the drawings and showing its function and effect.

For example, the seat support A of the present invention is provided between the user's body and the position where the hips, hips, back, neck, etc. of the seat 3 come into contact, that is, the portion of the seat 3 that is required to hold. When the seat support A is set and the user presses and deforms the seat support A while seated, the sheet-shaped covering body 2 impregnated with the cured resin is cured into the press-deformed shape, and the seat support A of the user's individual seating shape is set. It will be held in shape.

Therefore, it is possible to easily form the seat support A in the seating shape of the individual user, and the portion of the seat support A which is in contact with the seat 3 side is also seat 3.
Since it is solidified in a shape suitable for the above, it can be installed in a state in which it is unlikely to be displaced with respect to the sheet 3, and the sheet support A retains the shape by hardening of the covering body 2. Since the contents are the cushion body 1 having flexibility, not only the hardness but also the appropriate flexibility can be obtained, and good holding property and sitting comfort can be obtained.

Further, since the seat support A of the present invention can be constructed by simply covering the cushion body 1 with the coating body 2 impregnated with the cured resin, this construction is a construction that can be designed and realized easily, and mass production is possible. It is possible to provide low cost products with excellent properties.

Further, for example, the sheet-like covering body 2
If a cloth material, for example, a cotton cloth, is impregnated with a curable resin, the cloth material is very easily impregnated with the curable resin.
This sheet-shaped cover 2 can be more easily configured.

Further, for example, if the curable resin is one that is cured in a short time by exposing it to moisture or is cured in a short time by adding a catalyst liquid, the covering 2 is cured in a normal state. Since it does not occur, it is extremely easy to handle, and since it cures in a short time once it begins to cure, it is not necessary to take a sitting posture for a long time when molding the seat support A, and it is easier to mold it to the seating shape of the individual user. It will be possible.

Further, for example, if the cushion body 1 is made of a block-shaped flexible material, since the block-shaped cushion body 1 has an appropriate thickness, it is sufficient to hold the body by molding. The seat support A having a holding property can be molded, and the cushion body 1 having this thickness can provide an extremely good sitting comfort.

Further, for example, in the case where the cover body 4 is covered with a flexible cover body 4, the user can impregnate the cured resin by touching the cover body 4 during handling. Since it is possible to prevent the covering body 2 from touching, it is possible to handle the sheet support A of the present invention with bare hands, and it becomes easier to handle.

Further, for example, if the seat 3 is constructed so that it can be held by a holding portion 5 provided at a position where the body part such as the hips, hips, back, and neck of the seat 3 comes into contact, the holdability of the seat 3 is required. The seat support A of the present invention can be easily applied to the part
In addition to being able to hold the sheet support A, the sheet support A can be formed more easily while being held by the holding portion 5, so that it is easier to handle.

Further, for example, it is hermetically housed in a moisture-proof bag 6,
The cover 2 is configured to be cured in a short time by opening the moisture-proof bag 6 and exposing it to moisture, or the cover 2 is opened by opening the moisture-proof bag 6 and adding a catalyst solution.
However, if the coating 2 is cured in a short time, the coating 2 can be surely prevented from being cured unless it is taken out from the moisture-proof bag 6, so that handling such as transportation and distribution can be easily performed.

[0021]

Embodiments of the present invention will be described with reference to the drawings.

As shown in FIGS. 1 and 2, the seat 3 of this embodiment is applied to the automobile seat 3.

In this embodiment, the cushion support 1 having flexibility is covered with a sheet-shaped cover 2 impregnated with a cured resin to form a seat support A.

More specifically, the cushion body 1 has
It is made of block-shaped flexible material. More specifically, as shown in FIG. 2, as the flexible material, a horizontally long block-shaped foam material having flexibility and breathability such as sponge is adopted.

Further, the size of the cushion body 1 is set to be slightly larger than the body width of the part to be applied, and the cushion part 1 is configured to hold the part to be applied so as to wrap the part so that a very good support effect can be obtained.

The cover 2 is formed by impregnating a cloth material with a cured resin. More specifically, cotton cloth is used as the cloth material.

Further, in this embodiment, the covering body 2 is constructed so as to cover substantially the entire cushion body 1.

To further explain, in this embodiment, two coating bodies 2 are used, and the coating bodies 2 are superposed on and brought into contact with the upper and lower surfaces of the cushion body 1 in FIG. 3, respectively. By fixing all the peripheral edge portions of the covering body 2 to each other, the entire cushioning body 1 is covered with the two covering bodies 2.

It should be noted that when the fastening portions between the two covering bodies 2 are located on the peripheral side surface portion of the cushion body 1 in FIG. 3, the upper and lower surface portions of the seat support A are pressed to perform molding. The peripheral edge portions of the two cover bodies 2 largely squeeze out to the outside of the peripheral side surface of the cushion body 1 as the cushion body 1 is compressed and deformed. Then, since the protruding fastening portion does not have the cushion body 1 inside, it becomes stiff, and there is a risk that the comfort of sitting will be impaired.

Therefore, in this embodiment, in order to solve this point, as shown in FIG. 4, the two fastening members are arranged so that the fastening portions are located on the upper and lower surface portions of the cushion body 1 instead of the peripheral side surface portions. The two peripheral portions are fixed to each other. That is,
When the cushion body 1 is thus fixed, the cushion body 1 does not largely squeeze outward in the circumferential side surface when the cushion body 1 is deformed by pressing, so that good cushioning properties can be obtained even in the place where the fastening portion exists. 4A shows the case where the fastening portions are located on both upper and lower surfaces of the cushion body 1, and FIG. 4B shows the fastening portion on either one of the upper and lower surfaces of the cushion body 1. Only the position is shown.

The fastening means for the two coverings 2 is preferably a simple fastening means such as sewing, tape fastening, clip fastening or stapler fastening.

The curable resin to be impregnated in the cover 2 is a moisture curable resin such as moisture curable urethane which has the property of being cured in a short time by being exposed to moisture such as adding water or containing water. is doing.

In addition to these, as the optimum one for the covering body 2 of the present embodiment which satisfies these conditions, for example,
Casting products manufactured by 3M Healthcare Co., Ltd. are commercially available. This casting product has the property of hardening strongly and firmly in a short time (3 to 5 minutes) when immersed in water.

The curable resin may be, for example, one having a property of being cured (catalyst curable resin) in a short time by adding (spraying) a catalyst liquid to the main agent, or having other properties. Although it may be any one, it is convenient for transportation and distribution if it is cured by some kind of trigger as in this embodiment because it does not usually cure, and the sheet support A is molded in a timely manner. Desirable because it can.

Also, the seat support A of this embodiment
Are sealed and stored in a moisture-proof bag 6 as shown in FIG. Therefore, since the covering body 2 is not exposed to moisture in this stored state, it can be reliably prevented from being cured, and the moisture-proof bag 6 can be opened and exposed to moisture such as adding water or containing water. The coating 2 is configured to cure in a short time.

Further, the seat support A of this embodiment is constructed so as to be held by the holding portion 5 provided on the seat 3.

More specifically, in the present embodiment, as shown in FIGS. 1, 2 and 6, the holding portion 5 is provided on the seat cover 7 that covers the seat 3.

More specifically, the backrest portion 3A of the seat 3
It is provided on the backrest cover 7A to be covered and attached to the backrest cover 7A.
A side opening type storage bag capable of storing the seat support A of this embodiment is formed, and this storage bag is used as the holding portion 5. That is, the present embodiment shows a usage state in which the seat support functioning to support the user's waist is used.

Further, a fastener 8 is provided on a side surface of the backrest cover 7A, and the seat support A can be taken in and out by opening and closing the side opening of the holding portion 5 by opening and closing the fastener 8. Therefore, when the fastener 8 is closed, the seat support A is completely invisible,
In this holding (equipped) state, the appearance of the sheet 3 is kept extremely excellent. Reference numeral 3B in the drawing is a headrest.

Heretofore, an embodiment (first embodiment) of the seat support A in which the cushion body 1 is covered with the covering body 2 has been shown so far, but FIG.
An example (second example) of a sheet support A formed by covering (surrounding) the cover body 2 with a more flexible cover body 4 is shown.

More specifically, the cover body 4 is made of a thin foam material having flexibility and air permeability, and the sheet-like cover body 4 covers substantially the entire cover body 2. . Further, the cover body 4 is set to have a thin thickness so that the seat support A itself does not become too large and the cushioning effect when seated is good.

Therefore, according to the second embodiment, it is possible to reliably prevent the sheet 3 from being soiled by the cured resin, and the user touches the cover body 4 when handling the sheet. It is possible to reliably prevent the coating body 2 impregnated with the cured resin from being touched, and thus the sheet support A can be handled with bare hands to perform the molding operation, which makes the handling easier.

Further, since the structure of the first embodiment is covered with the foam (cover body 4) having further flexibility, better cushioning properties than those of the first embodiment can be obtained, and this cover is also provided. Since the body 4 also has breathability and does not lose its shape, a better sitting comfort can be obtained.

Further, in this embodiment, one cover 2 is wrapped around the cushion 1 to cover it, and the fastening portions at both ends of the cover 2 are provided on either the upper or lower surface of the cushion 1. The case where it is located on the side is shown.

Since the other construction is the same as that of the first embodiment, detailed illustration and description thereof will be omitted.

Next, a specific method of using the first and second embodiments will be described.

The sheet support A is taken out from the moisture-proof bag 6.

After dipping the sheet support A in water or adding water to the covering body 2, the water content is wiped off. Although the sheet support A of the second embodiment can be handled with bare hands, the sheet support A of the first embodiment is in a state where the coating 2 impregnated with the cured resin is exposed. Put on and do.

At this time, the cured resin impregnated in the coating 2 has a property of being cured by being exposed to moisture such as addition of water or inclusion of water, and thus begins to be cured.

The fastener 8 of the seat cover 7 (backrest cover 7A) covering and attached to the backrest portion 3A of the seat 3 is opened, and the horizontally long seat support A of this embodiment is inserted into the holding portion 5 in a standing state. Hold and close fastener 8.

Then, when the user presses and deforms the seat support A while sitting down, a short time (3 to 5 minutes)
Then, the cover body 2 is solidified in this pressed and deformed form, and the cushion body 1 is also kept in a deformed state by the solidified layer (cover body 2).

Therefore, in the present embodiment, since it is configured as described above, it is possible to easily form the seat support A having the seating shape of the user in a short time and to contact the seat support A on the seat 3 side. Since the portion that is also solidified in a shape suitable for the sheet 3, it can be installed in a state in which it is difficult to be displaced with respect to the sheet 3, and this sheet support A retains its shape as the cover 2 is cured. Since it is a cushion body 1 having flexibility and breathability, it is not only hard, but also has appropriate flexibility, and since it is breathable, it does not distort during long-term use. Therefore, good holdability and sitting comfort can be obtained.

Further, the seat support A of this embodiment can be constructed by simply covering the block-shaped foam material (cushion body 1) with the cotton cloth (covering body 2) impregnated with the cured resin. It is a configuration that can be easily designed and implemented,
It is possible to provide inexpensive products with excellent mass productivity.

Since the sheet-shaped cover 2 is formed by impregnating a cotton cloth with a cured resin, the cotton cloth can be easily impregnated with the cured resin, and the sheet-shaped cover 2 can be easily constructed. It will be possible.

Further, conventionally, an attempt was made to obtain a sheet support A by impregnating a foamed body having communicating cells with a cured resin, but with this structure, a new curing is inevitable in order to inject the cured resin into the foamed body. Resin injection equipment is needed.

In this respect, according to this embodiment (the present invention), since the cotton cloth is impregnated with the curable resin, the covering 2 which is hardened by utilizing the existing equipment to the existing material can be easily constructed. Above, with this cover body 2, a cushion body 1 such as a sponge
Since the seat support A exhibiting the above-described operation effect can be formed only by coating the sheet support, it is possible to provide the seat support A having a simple structure which is inexpensive and is excellent in mass productivity.

Further, since it is hermetically stored in the moisture-proof bag 6, the cover 2 is surely provided unless it is taken out from the moisture-proof bag 6.
It can be prevented from hardening, and handling such as transportation and distribution becomes extremely easy.

[0058]

Since the present invention is configured as described above, it can be easily formed into a seat support of a user's seating shape, and the portion of the seat support in contact with the seat side also fits the seat. Because it solidifies in shape,
The seat support can be provided in a state in which it is unlikely to be misaligned with the seat. Moreover, the seat support is a cushion that has a flexible structure and retains its shape, but the content is a soft cushion. In addition, appropriate flexibility can be obtained, and good holding property and sitting comfort can be obtained. Moreover, the present invention can be configured by simply covering the cushion body with the coating body impregnated with the cured resin. Therefore, this structure is a structure that can be easily designed and realized, and is an epoch-making seat support that exhibits excellent effects such as excellent mass productivity and the ability to provide inexpensive products.

Further, in the present invention, since the cloth material (for example, cotton cloth) is very easily impregnated with the cured resin, the above-mentioned sheet-shaped covering can be constructed more easily, which is extremely practical. It becomes a seat support.

According to the second aspect of the invention, since the cushion body is covered almost entirely with the cover body, the cover body covering substantially the entire body is hardened, so that the seat support more conforming to the body shape of the user when seated. It becomes a sheet support that is extremely practical and can be molded.

Further, in the invention according to claim 3 , since the covering does not harden in a normal state, it is extremely easy to handle, and once it begins to harden, it hardens in a short time. It is a seat support that is extremely practical, as it does not require a sitting posture and can be easily molded into the seating shape of the individual user.

Further, in the invention according to claim 4 , since the block-shaped cushion body has an appropriate thickness, it is possible to mold the seat support having a sufficient holding property for holding the body, and further, this thickness. The cushioned body provides a very good cushioning property (comfort) and is a very practical seat support.

In addition, in the invention described in claim 5 , the user can prevent the user from touching the cover body impregnated with the cured resin by touching the cover body during handling, so that the user can touch the cover body with bare hands. It is a seat support that can handle the seat support and is easy to handle and has excellent practicality.
