[0003]

However, since the conventional headrest skins have a large number of skin pieces, the number of stitched portions is increased and the sewing work is complicated. The number of skin pieces was large, so the number of cutting (punching) steps was increased. In addition, the seam line was inevitably long, and the appearance of the product was not very good.

The present invention solves the above problems, and an object of the present invention is to shorten the cutting and sewing operations, and further to provide a headrest skin that has a reduced number of seams and looks good as a product. .

[0005]

In order to achieve the above object,
The gist of the present invention according to claim 1 is one skin piece provided with a slit for injecting a foaming raw material, and another skin piece in which a pillow-shaped three-dimensional shape is formed by sewing with the skin piece. And a pair of through holes through which the stay is inserted are formed in any one of the one or other skin pieces. According to a second aspect of the present invention, in the headrest skin according to the first aspect, one of the skin pieces and the other skin piece are sewn together by overlock stitching.

According to a third aspect of the present invention, in the headrest skin according to the first or second aspect, a fold is formed on one skin piece so that the slit is arranged at a position depressed from the design surface. It is characterized in that the fold-formed peripheral edges of one skin piece are overlapped with each other and the folded portion is sewn together with the other skin piece peripheral edges. The headrest skin according to claim 4 is the headrest skin according to any one of claims 1 to 3, wherein one of the skin pieces has the slit positioned at the fold line of the fold, and the folds of both sides of the slit overlap each other. With respect to the above, an L-shaped stitch is formed from the fold line position at a predetermined distance from the slit to a stitching position with another peripheral edge of the epidermis. A headrest skin according to a fifth aspect of the present invention is the headrest according to the fourth aspect, wherein one of the skin pieces is formed with a dotted line-like hole or is cut and cut along the seam. It is characterized by being.

According to the first aspect of the present invention, since the skin covering the pillow portion of the headrest is completed with the two-piece skin piece, the cutting work is reduced and the sewing work is also reduced, so that the sewing work is performed. It will be easier than before. And the seam line is reduced, and the appearance of the finished headrest is improved. When the one skin piece and the other skin piece are sewn together by overlock stitching as in the invention described in claim 2, the sewing thread of the seam is doubled over the whole, and the seam is difficult to open.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the headrest skin according to the present invention will be described in detail below. (1) Embodiment 1 FIGS. 1 to 8 show an embodiment of the headrest skin of the present invention.
FIG. 1 is a plan view of one skin piece and another skin piece, and FIG. 2 is a sectional view of the one skin piece of FIG. 1 bent to form a fold, and FIG.
2 is a front view of FIG. 2, FIG. 4 is a sectional view showing a state in which one skin piece and another skin piece according to FIG. 3 are sewn together, and FIG. 5 is an L-shaped sewing formed on one skin piece. Enlarged perspective view of the eyes and their surroundings,
FIG. 6 is a completed perspective view of the headrest skin in an upside-down state, FIG. 7 is a sectional view in which an insert is attached to the headrest skin, and FIG. 8 is a sectional view showing a state in which a foaming raw material is injected from a slit. Applies to headrests attached to the top of the seat back of passenger cars.

In the headrest skin, the insert 6 is set in the pillow-shaped skin, the foaming raw material 5 is injected into the skin C, and the foam P is integrally molded with the bag-shaped skin in which the insert 6 is embedded. It is an integral molding type skin, and is composed of one skin piece 1 and another skin piece 2 cut into a predetermined shape.
The two skin pieces 1 and 2 are made of fabric skin or the like,
The corresponding edges are sewn together to form a shape that covers the pillow portion of the headrest. The first skin piece 1 is cut into a substantially elliptical shape, and margins for the overlapping portions 12 and 12 of the folds 11 are formed near one edge (FIG. 1).
Then, the fold line 13 of the overlapping portions 12 and 12
A slit 14 is provided at the center of the. The slit 14 is an elongated hole for injecting the foaming raw material 5 into the epidermis C, runs substantially parallel to the trailing edge, and is a cut having a size of about 30 to 100 mm. The slit 14 is also used when the two skin pieces 1, 2 are sewn in a pillow shape and then the skin pieces 1, 2 in the inside-out state are turned upside down. Code 16
Shows a pair of through holes for inserting the stay. In the present embodiment, the through hole 16 is provided in one skin piece 1, but the other skin piece 2 is provided.
You may provide the through hole 16 in.

The three-dimensional headrest skin for covering the pillow portion is obtained as follows. The one skin piece 1 is bent so that the slit 14 is located at the fold line 13 of the fold 11 (FIG. 2). Then, with respect to the overlapping portions 12 and 12 that become the folds 11 around the slit 14, from the position of the fold line 13 at a predetermined distance from the slit 14 to the stitching position T with another peripheral skin piece peripheral edge 21 to be described later, an L-shape. The seam 3 is formed in a shape (FIG. 3). Seam 3
Is sewn according to the lockstitch specification with the design surface E inside. The folds 11 are formed by the seams 3 and when the headrest skin is completed, the folds 11 are pushed into the inside C of the skin and the slits 14 are arranged at a position lower than the design surface E (FIG. 7).
The one skin piece 1 that has finished forming the folds 11 covers the front surface portion 1a, the bottom surface portion 1b, and the top surface portion 1c of the pillow portion, and the outer peripheral edge distances thereof are substantially the same as those of the other skin pieces 2.
As shown in FIG. 1, the other skin piece 2 has an almost elliptical shape similar to the racetrack shape for competition and serves to cover the back surface portion 2a and the side surface portions 2b, 2b of the pillow portion.

The one skin piece 1 in the state of FIG. 3 becomes a pillow-shaped three-dimensional shape by being sewn together with the other skin piece 2. As shown in FIG. 4, with the design surface E inside, for example, when the trailing edge portions 15 and 25 are overlapped with each other and both peripheral edges are sewn, a pillow shape is formed. When the facing portions of the peripheral edges of the two skin pieces are overlapped and joined by a sewing thread m, and when the stitch has reached the stage where it has reached the starting point, lap stitch w is carried out so as not to cause fraying (FIG. 6). The suture line 4 is formed on the bottom edge of the rear edge portion, which corresponds to the bottom surface of the pillow portion, and on the bottom sides of both side edge portions, and improves the appearance of the pillow portion even with a headrest skin that is formed from two skin pieces. Here, it is preferable that the suture S between the one outer skin piece 1 and the other outer skin piece 2 is performed by overlock sewing. This is because if the headrest is made of a skin sewn with the overlock stitching specification, it is possible to prevent the foaming raw material 5 from leaking during foam molding without sticking urethane tape to the needle hole or applying an adhesive. Overlock sewing eliminates the need for materials such as urethane tape and eliminates the work of attaching urethane tape, which greatly contributes to labor saving.

By the way, regarding the suture S between the root portion of the folds 11 of the one skin piece 1 and the other skin piece 2, the folds 1 forming the folds are overlapped and folded.
It is preferable to sew 7 together with another peripheral edge 21 of the epidermis (FIG. 5). In order to make sewing easier, for example, when a cut is made in the base portion of the fold 11 and the other skin piece 2 is sewn,
It is highly possible that the foaming raw material 5 leaks from the cut portion during foam molding. On the other hand, although it is sewn in an unreasonable state, when the portion 17 folded in a twisted manner is sewn to the other skin piece 2, leakage of the foam raw material 5 from the root portion of the fold 11 is suppressed during foam molding. .

Thus, a three-dimensional headrest skin covering the pillow portion is completed (FIG. 6). However, FIG.
Is an inside-out skin, and when actually manufacturing the headrest, the seam allowance 41 is hidden, and the slit 14 is turned upside down so that the design surface E is exposed. Next, as shown in FIG. 7, after the insert base 61 is placed in the skin C and the stay 61 is inserted into the through hole 16, the jig 7 and the funnel 71 are set in the recess u formed by the folds 11 that are overlapped. To do. Then, the foaming raw material 5 is injected into the inside C of the skin to perform integral molding of the skin (FIG. 8). In this way, the headrest as the final product with the integrated skin is completed in the foam mold.

As a material for the two skin pieces (one skin piece 1 and the other skin piece 2) used in this embodiment, a fabric skin or the like is generally used. Specifically, the fabric skin is made of a solid material. A polyurethane film lining, a urethane foam sheet on a fabric skin, and a polyurethane film integrally laminated are used. Alternatively, a cut pile fabric made of synthetic fibers such as acrylic or polyamide as pile yarn and ground with cotton, rayon or the like may be used. A resin coating is applied to the cut pile fabric for the purpose of preventing the pile fabric from coming off the pile.

In the headrest skin thus constructed, the foaming raw material 5 is injected while the sewing finish with the two skin pieces 1 and 2 is performed, and the pillow-shaped foam P formed by integral molding of the skin is finely applied. And since the skin for headrest is made with two skin pieces 1 and 2 less than before,
The work load for cutting is reduced, and along with this, the number of stitched portions is inevitably reduced, which facilitates the sewing work. In addition, the seam line 4 is reduced, and the appearance of the headrest as a product is improved.

Further, when the peripheral edges of the two skin pieces are overlapped with each other and sewn into a pillow-shaped three-dimensional shape, the seam is hard to open because the overlock stitching specification is used, and the foam raw material starts from here during foam molding. The problem that 5 leaks out does not occur. If the peripheral edges of the two skin pieces are sewn together by overlock stitching, the sewing thread of the seam will be doubled over the whole, so even if tension is applied by the foaming pressure, the tension applied to the seam of the seam is dispersed, Is hard to open. As a result, it becomes difficult for the foaming raw material 5 to leak through the needle hole.
As for the folds 11 as well, since the peripheral edges thereof are overlapped and further folded and sewn to the other peripheral edge 21 of the outer skin piece by overlock stitching, the leakage of the foaming raw material 5 from here can be suppressed during foam molding. Furthermore, slit 1
4 is positioned on the fold line 13 of the fold 11 and the L-shaped seam 3 is formed in the overlapping portion 12 of the folds 11 on both sides of the slit 14, the jig 7 for injecting the foam raw material 5 as shown in FIG. Can be locked and set in the recess u, so that the foaming raw material 5 can be smoothly injected into the skin C.

(2) Embodiment 2 In this embodiment, as shown in FIGS. 9 and 10, one skin piece 1 is used.
The peripheral edge portion forming the fold 11 is slightly cut out, and diagonal cut portions 181 are provided at both ends of the cutout. Then, the peripheral edges of the folds 11 are overlapped with each other and further folded, and the overlapped portion 12 is sewn to the other peripheral edge 21 of the epidermis by overlock stitching. In addition, one skin piece 1 has an L-shaped seam 3
Along the seam while keeping a certain distance to
(Perforation) is formed. The cutout portion 18 and the hole f are formed at the same time when the one skin piece 1 is cut. Other configurations are the same as those in the first embodiment. In addition to the function and effect of the first embodiment, the headrest skin thus configured prevents the foaming raw material 5 from leaking at the root portion of the folds 11 during foam molding, and overlaps the peripheral edges of the folds 11 with each other. It can be easily folded and sewn to the other peripheral edge 21 of the epidermis. Further, the dotted line-shaped hole f serves as a mark to facilitate the work of the L-shaped seam 3. The two-dot chain line in FIG. 9 indicates the position of the stitch line.

(3) Embodiment 3 In this embodiment, as shown in FIG. 11, a notch 19 is provided in the peripheral edge portion forming the fold 11 of one skin piece 1. Regarding one skin piece 1, the outer portion of the L-shaped seam 3 is originally an unnecessary portion, and in the present embodiment, such a portion is arranged along the L-shape seam to make the one skin piece 1 It was cut at the same time when cutting. Also in the headrest skin constructed in this manner, it is easy to sew L-shaped seams using the notches 19 as a guide, so that sewing is easy. Other configurations, operations, and effects are the same as those of the second embodiment.

In the present invention, the present invention is not limited to the above-described embodiment, but can be variously changed within the scope of the present invention depending on the purpose and application. One piece of epidermis 1, another piece of epidermis 2, folds 1
The shapes and sizes of the slits 14 and the like can be appropriately selected according to the application. The through hole 16 for inserting the stay is the other skin piece 2
May be provided.

[0020]

As described above, the headrest skin of the present invention is composed of only two skin pieces, which contributes to shortening of the work time for cutting and sewing, and the reduction of stitch lines. It also has an excellent effect on improving the appearance of the headrest.
