Description

[Detailed Description of the Invention] [JII: Field of Application of Industry-H] The present invention relates to a seat for vehicles, furniture, etc., and in particular, a seat in which a skin member of the seat is suspended toward a bottom plate.
The present invention relates to a sheet with suspension and a suspension method.

[Prior Art] Conventionally, in a seat with a hanging device, a hole is drilled in the cushioning material, and the hole is used to attach a string material as a hanging device.
The skin member was suspended toward the bottom plate by engaging with the skin member and the locking tool. That is, as shown in FIG. 6, the bottom plate 31. Consisting of a cushion material 32 and a skin member 33, the skin member 33. consists of an epidermis 34, a wadding 35, and a wadding 36. A string material 37 as a sheet hanging tool is attached to the back side of the temple skin member 33 at a predetermined location. Skin member 3
3 is hung by the hanging string material 37 passing through the vertical hole 38 of the cushioning material 32 and being pulled toward the bottom plate 31 side. Bottom plate 31 of string material 37
As for the side locking structure, a clip or other locking tool 39 is used to lock between the bottom plate 31 and the cushion material 32 corresponding to the attachment position of the string material 37.

[Problems to be Solved by the Invention] As described above, in the conventional hanging technology, a string material for hanging and a locking tool for fixing the string material are used on the skin member. In addition, when suspending, it was necessary to suspend each location individually, so the number of parts was reduced.
There were problems with the number of steps, assembly work time, etc. The present invention provides a hanging device that can adjust the degree of hanging without using a string material as a hanging tool that was conventionally necessary for hanging, and a locking device for locking this string material. Provides sheets and also
A technical problem is to provide a method for suspending such a sheet.

[Means for Solving the Problems] In order to solve the above-mentioned technical problems, the present invention provides a seat that includes at least a skin member, a cushioning material, and a bottom plate, by providing holes at predetermined locations in the cushioning material. A film material is provided integrally with the cushion material at a desired position of the chain hole, and the film material and the skin member are joined to form a structure in which the skin member is suspended.

In addition, in order to form a sheet with this suspension, a mold of a desired shape is used to form a desired number of holes in predetermined locations of the cushioning material, a film material is placed in a desired position within the holes, and the sheet is integrally foamed. A cushioning material is formed using the cushioning material, and a skin member having at least a skin material is placed on the cushioning material. Then, the film material provided in the hole of this cushioning material and the skin member are joined, and the skin member is suspended.

[Function] The present invention provides a hole at a desired location of a cushion material, and joins a film material provided at a desired position of the chain hole and a skin member placed on the cushion material to form a skin member. Since the structure is suspended, the film material joins with the skin member and draws the skin member toward the bottom plate. For this reason, in a sheet having a hanging device, there is no need to use a string material as a hanging tool as in the past, and since this string material is not used, there is no need for a locking device for locking the string material. Furthermore, since the film material can be placed at a desired position of the hole provided in the cushion material, the position of the film material in the hole can be changed. By changing the position of the film material, the degree of suspension can be adjusted. In other words, the closer the film material is placed on the cushion material to the bottom plate, the more the degree of suspension increases.

In addition, in order to form a sheet having such suspensions, a desired number of holes and a film material are arranged at desired positions within the holes at predetermined locations of the cushioning material, and the desired number of holes can be formed by integrally foaming the film material. Since the cushioning material is formed using a shaped mold, the film material and the cushioning material are integrated,
It also has sufficient strength. Furthermore, since integral foaming is performed, the formation of the film material itself is simple. Then, a skin member having at least a skin is placed on this cushion material, and in order to join the film material provided in the hole of this cushion material and the skin material, each There is no need to hang each hole individually, which simplifies assembly.

[Example] FIG. 1 is a partial sectional view of a main part showing an example of applying the seat suspension structure according to the present invention to a motorcycle seat,
Fig. 2 is an explanatory diagram of encapsulating the skin member in the cushioning material, Fig. 3 is a partial sectional view taken along the line ■-■ of the cushioning material in Fig. 2, and Figs. It is an explanatory view when joining the thing which covered.

In the figure, a motorcycle seat S includes a bottom plate 1, a cushion material 2, and a skin member 3. The skin member 3 in this example is formed from a skin material 4, a wadding material 5, and a wadding cover 6. Then, a hole 7 is bored at a predetermined location in the cushion material 2, and a film material 8 is provided at a desired position within the hole 7. The film material 8 is formed integrally with the cushion material 2 when the cushion material 2 is foamed. The film material 8 provided on the cushion material 2 and the skin member 3 are joined together, and the skin member 3 is drawn toward the bottom plate 1 to perform hanging. The position of the film material 8 in the hole 7 is adjusted as appropriate depending on the type of sheet to be hung. That is, if you want to increase the degree of suspension, placing the film material closer to the bottom plate will result in deeper suspension, and placing it closer to the skin member will result in shallower suspension.

Next, a method for suspending such a sheet will be explained. As shown in FIG. 2, the cushioning material 2 is foam-molded. At that time, the film material 8 is placed in a desired position of a mold (not shown), and the film material 8 is placed in the desired position of the hole 7 provided in the cushioning material 2. and is formed integrally with the cushioning material 2. In this way, the film material 8 is formed at the predetermined position of the hole 7 provided in the cushion material 2, as shown in FIG. As the material of the cushion material 2, a material suitable for foaming, such as semi-rigid urethane foam, is used, for example. The film material 8 may be made of a PVC leather film or a soft material such as cloth, but in this example, any material that can be welded is used. Therefore, it is preferable for cloth etc. to be impregnated with a PVC solvent solution. The skin member 3 is encapsulated in the cushion material 2 configured in this way (see FIG. 2). The skin member 3 in this example includes a skin material 4, a wadding material 5,
It consists of a wadding cover 6, etc., but it goes without saying that it may be a single piece of skin material.

Next, a method for hanging such a sheet will be explained.

FIGS. 4 and 5 show how the skin member 3 is joined to the film material 8 provided in the hole 7 in the cushion material 2 configured as described above.
In the illustrated example, high frequency welding is performed. In other words, cushion material 2 and skin material 3 are placed on high-frequency welding mold B.
is set, and the Welg type A is operated to weld the skin member 3 to the film material 8 formed at the desired position of the hole 7 drilled in the cushion material 2.

Since the welder mold in this example has six parts that require suspension, the welder mold electrodes also have six convex shapes. In this way, by using the same number of mold electrodes as the number of holes drilled in the cushion material and joining them all at once, there is no need to hang each hole individually as in the past, making assembly easier. . Furthermore, depending on the type of sheet, the shapes of these molded electrodes can be deformed or modified into desired shapes. In other words, it may be formed using only one type electrode. Furthermore, in this example,
Although high-frequency welding was performed, the means for joining the film material and the skin member is not limited to high-frequency welding. For example, processing using internal heating such as ultrasonic waves and microwaves,
Processing using external heating using hot air, infrared heaters, etc.
It is used as long as its characteristics are suitable for the present invention. Alternatively, an adhesive or the like may be used between the film material and the skin member to press them together. When an adhesive is used in this way, it goes without saying that the material of the film material does not have to be suitable for welding.

In addition, conventionally, a pattern or a pattern of a certain shape was used on the surface of the skin to give it a good appearance and marketability. A desired shape such as a groove can be formed on the surface of the material and a skin material is bonded thereto, and by combining this with the suspension of the present invention, a patterned shape or pattern can be obtained.

[Effects of the Invention] Since the present invention is configured as described above, it has the following effects.

■ Unlike conventional methods, there is no need to use string material as a hanging device, and since this string material is not used, there is no need for a locking device to lock the string material, reducing the number of parts and making assembly easier. becomes.

■Furthermore, at the desired position of the hole provided in the cushioning material,
Since the film material can be placed, the degree of suspension can be adjusted by changing the position of the film material in the hole. In other words, the closer the film material is to the bottom plate, the more the degree of suspension increases, and the closer the film material is to the skin member, the shallower the degree of suspension.

■In addition, in order to form a sheet with such hangings, a desired number of holes are placed at predetermined locations in the cushioning material, a film material is placed at a desired position within these holes, and the desired shape is formed by integrally foaming. Since the cushioning material is formed using the mold, the film material and the cushioning material are integrated, and the material has sufficient strength.

■Also, since the cushioning material and the film material are integrated, the formation of the film material itself is easy.

Note that, as a matter of course, the present invention is not limited to the illustrated example.
