Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a seat skin constituting furniture or seats of aircraft, ships, automobiles, etc., and particularly for seats of motorcycles, boats, etc. that are likely to be exposed to water. The present invention relates to a method for manufacturing a suitable seat skin.

Using conventional technology, the seat skin exudes luxury and also serves as a non-slip material. Sewing is applied when the skin material, wadding material, and backing material are joined together, and the seat skin A hanging bag used to attach the cushion body to the cushion body is integrally attached.

Conventionally, with this method of sewing, there is a risk that rain or spilled water may enter the interior through the seams and moisten the shoe body made of polyurethane foam, resulting in deterioration of the properties or quality. The seat skin is attached by applying a sealant such as an adhesive along the seam on the back side or by laying a waterproof film such as PvC to cover the cushion body.

Problems to be Solved by the Invention However, when the sealant is applied along the seams, there is a risk that the sealant will harden into a lump and the area where the hanging bag is attached will become thicker, giving the seater a feeling of a foreign body. In addition, when using a waterproof film, the film is slippery and difficult to position, making it time-consuming to cover the seat skin, and the disadvantage is that it makes the seat skin slippery and makes the seating surface unstable. There is. In addition, the waterproof film may slide up to the side surfaces of the seat and curl up, creating irregularities on the outer surface of the seat cover, which may make the seat look unsightly.

Means for Solving the Problems In the method for manufacturing a seat skin according to the present invention, after the backing material is hung down and the skin material and wadding material are sewn together, this sewing part is located on the inside. Fold the hanging part of the lining material to the back side of the lining material, weld the base of the folded material to the lining material, seal the sewn part on the inside, and form a hanging bag with the remaining folded material. It is like that.

Function: In the seat skin manufactured in this way, uneven seams caused by sewing the skin material, wadding material, and backing material together are watertightly sealed with the folded margin with the backing material hanging down and the base welded. Moreover, since the hanging bag is formed with a continuous folding margin from the lining material, it is possible to construct a seat that prevents water from entering, does not give a feeling of discomfort to the seater, and has a stable seat surface.

Embodiments will now be described with reference to the accompanying drawings.

This sheet skin is made of skin material 1. Wadding material 2 and lining material 3 are sewn together with thread 4 to form a trim cover. The skin material 1 can be a woven fabric, non-woven fabric, embroidered cloth or synthetic resin film made of natural or synthetic fibers, the wadding material 2 can be a urethane slab, and the lining material 3 can be waterproof. A combination of materials that can be welded easily! It is possible to use an It resin film.

These three constituent materials are first co-stitched together. At the time of sewing, the backing material 3 is sewn together with a relatively large droop within each sewing interval. Drop part 3 onto backing material 3 with R...
A, 3a... are formed and the three parts are sewn together using sewing machine needles P, P... (see Figure 2). After sewing, cut to an appropriate size and create a hanging part 3a. , 3a・
... by inserting each arm of the rake-shaped jig H (see Figure 3) and sliding it, the hanging portion 3a,
3a... is pulled in a certain direction. This tension causes the thread sewing parts 4a, 4a... to hang down parts 3a, 3a...
・Do it in the direction that is located on the inside of the fold, and fold the fold 3a
', 3a'... is made flat on the back side of the backing material 3 (see Figure 4).
, 3a'... join the bases located near the sewing points 4a, 4a... to the backing material 3 in a watertight manner. For joining, the welding can be done by heating with a high frequency welder or a heater bar. In the case of welder welding, the lower die WI is inserted between the wadding material 2 and the backing material 3, and the folding margins 3a', 3a', The base sides of .
It has a bag shape along the radial direction, and by hanging it downward, it can be used as a hanging bag.

In the seat skin manufactured in this way, the hanging bag 3a
By inserting the listing wire 5 into the listing wire 5 and hooking the tension spring 6 or the 0-shaped clip to the listing wire 5 and connecting it to the 5-shaped spring, the frame 7, etc., it can be attached to the cushion pad 8. . In the attached state, the seams can be sealed by positioning each sewing location 4a inside the folding margin 3a' and joining the base of each folding margin 3a' in a watertight manner. Water is prevented from entering the cover body 8 of the cook 1. In addition, by joining the base of the folding margin 3a' to the lining material 3, a concave-convex pattern that can be formed by thread stitching is held in tension, and a hanging pattern is formed continuously from the point with the remaining folding margin 3a'. Since the seat skin is stretched by the bag, this shift skin is not only waterproof, but also has a large uneven pattern formed by the wadding material 2 and can be installed with good shape retention.

Effects of the Invention As described above, according to the method for manufacturing a seat skin according to the present invention, a seat skin with good waterproofness can be easily manufactured by integrating a seat suspension bag without using a separate material. The seat cover has good decorative properties, and the seat surface does not feel uncomfortable, making it possible to construct a stable seat.

Claims (1)

[Claims] After letting the lining material hang down and sewing the skin material and wadding material together, fold the hanging part of the lining material to the back side of the lining material so that this sewn part is located on the inside, and then A method for manufacturing a seat skin, which comprises welding the base to a backing material, sealing the sewn part on the inside, and forming a hanging bag with the remaining folding allowance.
