Description

[Detailed Description of the Invention] The disclosed technology belongs to a patchwork-style sewing technology for loose cushion seats for automobile seats.

Therefore, this invention involves sewing together seam slits provided radially from the button in a loose cushion type in which the seat skin is pulled in by a button to the pad of the seat provided in the automobile, etc. In particular, it is possible to create a patchwork-like seat with a rich three-dimensional effect by simply sewing the radial seam slits separated by the setting button attachment part of one sheet of seat skin. The invention relates to a patchwork sheet skin structure that makes it possible.

As is well known, the seats installed in vehicles such as automobiles not only provide occupant comfort and reduce fatigue while driving, but also have aesthetic features that improve the design and appearance of the vehicle. Various improvements have been made to take into account the design.

Among these, a so-called button retractable loose cushion type seat was devised, which had a cushion area shaped like a block, had independent flexible parts as much as possible, and also had an excellent design. Furthermore, luxurious seats with patchwork on the seat skin have started to be adopted.

As shown in FIG. 1, the loose cushion type patch worksheet 1 has unit patches 3, 3, .
. . , and the retraction buttons 5° 5 . . . form a radial network of the seams 4, 4 .

Therefore, as shown in FIG. 2, a design wrinkle 6 is formed on the Hodanbutton part 5 which is narrowed and sewn to improve the design.

Up until now, when creating the patchwork-like sheet skin 2, the unit patch 3 has been used as shown in FIG.
, 3... Patch sheets 7゜7... are individually cut from the raw material one by one and set, and radial seam slits are made for the upper button portions 8, 8... respectively. 9,9・
The stitches 10, 10, etc. were sewn to each other so that there were...

However, in this type of conventional technology, each patch sheet 7.7.
Not only does this have the disadvantage of being extremely careful in cutting, arranging, and managing it, but it also has the disadvantage of requiring great skill to sew, and the quality of the finished products tends to vary.

Further, cutting out the patch sheets 7.7... from the raw material also requires a technique, which has the disadvantage of often leading to poor yields.

The purpose of this invention was to solve the problem of the patchwork-like seat surface of the loose cushion seat based on the above-mentioned conventional technology.
To provide an excellent seat skin structure in which a patchwork-like seat skin as designed is obtained by sewing seam slits provided in one sheet of seat skin.

The structure of this invention in accordance with the above object is to provide one raw skin sheet with seam slits that radiate from the button part so as to be discontinuous at the button part and are separated by each button part,
The gist of this invention is to make sewing easy and accurate by sewing the seam slits, and to obtain a patchwork-like seat skin of a loose cushion seat as set.

Next, an embodiment of this invention will be described below based on the drawings from FIG. 4 onwards.

Note that the same parts as in FIGS. 1 to 3 will be described with the same reference numerals.

In the embodiment shown in FIGS. 4 and 5, reference numeral 11 is a seat skin made of a predetermined material similar to the conventional one, the outer shape of which is set to the seat, and is continuously integrated with the seat through setting button parts 8, 8... The seam slits 9', 9', . . . are split in the setting direction from the button portions 8, 8, .

In order to form the same patchwork-like sheet skin 2 as shown in FIGS. 1 and 2, the seams 10', 10', etc. are folded back about the axis C-C and sewn together. This allows the seat skin 2 to be easily sewn.

Particularly in this case, there is no need to perform any gear stitching of the button portion 8, and the stitching can be performed smoothly and accurately.

By inserting unidirectionally arranged seam slits 9'', 9'', etc. as in the embodiment shown in FIG. 5, it becomes possible to create various patchwork textures.

In short, the button parts 8 are connected to each other, and the seat skin 1 is connected to the button part 8.
1 and the installed seam slit 9/
, g''-... are isolated from each other, and I would like to sew the separate pieces together in a single layer.

Further, on the back side of the seat skin 2, as shown in Figs. 6 and 7, a cover pad 12 with a thickness of about 10 mm is sewn together with the seam 10', as shown in a, b, and c. By changing the sewing method, the appearance of wrinkles 4, 4, etc. can be changed, and various textures can be created.

Therefore, it goes without saying that the embodiments of this invention are not limited to the above-mentioned embodiments. For example, a cross-shaped seam slit may be inserted inside the patch sheet 7' surrounded by the installation seam slit. Multiple embodiments are possible, and it is also applicable to ordinary seat upholstery.

As mentioned above, according to this invention, in the button retractable seat of the loose cushion seat of the seat, the single raw material seat skin is not cut into parts, and the seam slit is separated by the button part. The seam slits are formed in a radial pattern, and the seam slits are folded back and sewn to form a patchwork-like sheet skin. Basically, the sewn patchwork-like sheet skin is easy to sew and can be sewn without any skill. Since it can be done and done accurately, the stitching accuracy is extremely good, and therefore, the quality of the products is good, and even when mass-produced, it has the excellent effect of being able to produce the same quality and accuracy.

Therefore, in the button part, the raw material sheet skin is one piece with the base material, and since the sewing thread is knitted continuously without cutting, the strength of the button retraction part, where the tensile stress caused by vibration is strongly applied, is sufficient. It also has the advantage of being able to be kept clean and free from the risk of tearing or flaking.

In addition, since it is made from a single sheet skin, the yield of raw materials is good, which also has the advantage of reducing costs.

Furthermore, since there is no need to sew multiple patch sheets together during sewing, the sewage efficiency is extremely high, and the sewing work is quick.
There is also the advantage of being precise.
