BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of a headrest skin according to the present invention will be described in detail. (1) Embodiment 1 FIGS. 1 to 8 show an embodiment of a headrest skin according to the present invention.
1 is a plan view of one skin piece and another skin piece. FIG. 2 is a cross-sectional view of the one skin piece of FIG.
2 is a front view of FIG. 2, FIG. 4 is a cross-sectional view showing a state in which one skin piece and another skin piece according to FIG. 3 are stitched, and FIG. 5 is an L-shaped sewing formed on one skin piece. An enlarged perspective view of the eye and its surroundings,
6 is a completed perspective view of the headrest skin in an inverted state, FIG. 7 is a cross-sectional view in which an insert is inserted into the headrest skin, and FIG. 8 is a cross-sectional view showing a state in which a foaming material is injected from a slit. Applies to headrests attached to the upper edge of the passenger car seat back.

In the headrest skin, after setting the insert 6 in the pillow-shaped skin, the foaming material 5 is injected into the skin C, and the foam P is integrally formed with the bag-shaped skin in which the insert 6 is embedded. It is an integrally molded 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 a fabric skin or the like,
The corresponding perimeter is sewn together to cover the headrest pillow. One of the skin pieces 1 is cut into an almost elliptical shape by cutting, and a margin is formed near one end edge of the fold 11 (FIG. 1).
Then, the fold line 13 of the overlapping portions 12 and 12
Is provided with a slit 14 in the center. The slit 14 is an elongated hole for injecting the foaming raw material 5 into the inside C of the skin, runs almost parallel to the trailing edge, and has a cut having a size of about 30 to 100 mm. Note that the slit 14 is also used when the two skin pieces 1 and 2 are sewn in a pillow shape, and then the skin pieces 1 and 2 in the inverted state are turned upside down. Code 16
Indicates a pair of through holes for stay insertion. In the present embodiment, the through-holes 16 are provided in one of the skin pieces 1, while the other skin pieces 2 are provided with the through-holes 16.
May be provided with a through hole 16.

A three-dimensional headrest skin covering the pillow portion is obtained as follows. One skin piece 1 is bent such 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, 12 which become the folds 11 around the slit 14, an L-shape is provided from a position of a fold line 13 at a predetermined distance to the slit 14 to a sewing position T with another skin piece peripheral edge 21 described later. A stitch 3 is formed in the shape (FIG. 3). Seam 3
Is sewn in the lockstitch specification with the design surface E inside. The fold 11 is formed by the seam 3, and when the headrest skin is completed, the fold 11 is pushed into the inside of the skin C and the slit 14 is arranged at a position below the design surface E (FIG. 7).
One of the skin pieces 1 on which the folds 11 have been formed covers the front part 1a, the bottom part 1b, and the top part 1c of the pillow portion, and the outer skin part 2 and the outer peripheral edge distance thereof are substantially equal.
As shown in FIG. 1, the other skin piece 2 has a substantially elliptical shape similar to the shape of a racing track, and has a role of covering the back portion 2a and the side portions 2b, 2b of the pillow portion.

One skin piece 1 in the state shown in FIG. 3 becomes a pillow-shaped three-dimensional shape by suturing with another skin piece 2. As shown in FIG. 4, for example, when the design surface E is set inside and the rear edge portions 15 and 25 are overlapped with each other and both peripheral edges are sewn, a pillow shape is obtained. When the opposing portions of the peripheral edges of the two epidermis pieces are overlapped and connected by a sewing thread m, and when the sewing has reached a stage where the sewing has completed one cycle, the overlapping stitch w is performed so that no fraying occurs (FIG. 6). The suturing line 4 is formed on the bottom edge of the trailing edge portion and the bottom edge portion on the bottom surface of the pillow portion, and improves the appearance of the pillow portion even with a headrest skin formed from two skin pieces. Here, it is preferable that the suture S between the one skin piece 1 and the other skin piece 2 is performed by overlock sewing. If the headrest is made of a skin sewn with the overlock sewing specification, leakage of the foam raw material 5 during foam molding can be prevented without sticking urethane tape or applying an adhesive to the needle hole. According to the overlock sewing, materials such as urethane tape are not required, and work such as attaching urethane tape is eliminated, which greatly contributes to labor saving.

By the way, as for the suture S between the root portion of the fold 11 of one skin piece 1 and the other skin piece 2, the peripheries forming the fold 11 are overlapped and folded.
It is preferable to suture S 7 together with other skin piece peripheral edges 21 (FIG. 5). To make sewing easier, for example, a cut is made at the base of the pleats 11 and sutured with the other epidermis piece 2,
There is a high possibility that the foaming raw material 5 leaks out of the cut during foam molding. On the other hand, although the sewing is performed in an impossible state, if the twisted folded portion 17 is sewn to the other skin piece 2, the leakage of the foaming material 5 from the root portion of the fold 11 during foam molding is suppressed. .

In this manner, a three-dimensional headrest skin covering the pillow is completed (FIG. 6). However, FIG.
Is a skin turned over, and when actually manufacturing the headrest, the seam allowance 41 is hidden and the design surface E is turned over using the slit 14 so that the design surface E is exposed. Next, as shown in FIG. 7, after the insert base 61 is arranged in the inner skin C and the stay 61 is inserted through the through hole 16, the jig 7 and the funnel 71 are set in the concave portion u formed by the folded pleats 11. I do. Thereafter, the foaming material 5 is injected into the inside of the skin C, and the skin is integrally formed (FIG. 8). In this way, a headrest as a final product in which the skin is integrated in the foaming mold is completed.

As a material of two skin pieces (one skin piece 1 and another skin piece 2) used in the present embodiment, a fabric skin or the like is generally used. Specifically, a solid skin is used for the fabric skin. A backing of a polyurethane film, 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.

While the headrest skin thus constructed is sewn and finished with the two skin pieces 1 and 2, the foaming material 5 is injected, and the pillow-shaped foam P formed by integral skin molding is adhered neatly. And, since the skin for headrest is made with two skin pieces 1 and 2 less than before,
The work load of the cutting is reduced, and in addition, the number of the sewn portions is inevitably reduced, which simplifies the sewing operation. In addition, the number of seam lines 4 is reduced, and the appearance of the headrest as a product is improved.

[0016] Further, when the outer edges of the two skin pieces are overlapped with each other and sewn into a three-dimensional pillow shape, the seam is hard to open because of the overlock stitching specification. There is no problem that 5 leaks out. If the peripheral edges of the two skin pieces are sewn by overlock sewing, the seam of the seam is doubled as a whole, so even if tension is applied by the foaming pressure, the tension applied to the seam of the seam is dispersed, and the seam is stitched. Is difficult to open. As a result, the foaming raw material 5 hardly leaks through the needle hole.
The folds 11 are also overlapped with each other at their peripheral edges and further folded, and sewn to the other peripheral edge 21 of the skin by overlock stitching. Therefore, it is possible to suppress the leakage of the foaming raw material 5 therefrom during foam molding. Furthermore, slit 1
When the L-shaped seam 3 is formed at the overlapping portion 12 of the fold 11 on both sides of the slit 14, the jig 7 for injecting the foaming raw material 5 as shown in FIG. Can be locked and set in the concave portion u, so that the foaming raw material 5 can be smoothly injected into the inside C of the skin.

(2) Embodiment 2 In this embodiment, as shown in FIG. 9 and FIG.
Is formed in a slightly notched state at a peripheral portion forming the fold 11, and oblique cut portions 181 are provided at both ends of the notch. Then, the peripheral edges of the folds 11 are overlapped and further folded, and the overlapped portion 12 is sewn with another peripheral edge 21 of the skin by overlock sewing. Further, one skin piece 1 has an L-shaped seam 3
While keeping a fixed distance to the seam, a dotted line f
(Perforations) are formed. These cutout portions 18 and holes f are formed simultaneously when one skin piece 1 is cut. Other configurations are the same as the first embodiment. In the headrest skin thus configured, in addition to the functions and effects of the first embodiment, the peripheral edges of the folds 11 are overlapped while preventing leakage of the foaming raw material 5 at the root portion of the folds 11 during foam molding. It can be easily folded and sewn to another skin piece peripheral edge 21. Further, the dotted line hole f serves as a mark, and the work of the L-shaped seam 3 becomes easy. 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 a peripheral portion forming a fold 11 of one skin piece 1. The outer portion of the L-shaped seam 3 of one skin piece 1 is essentially unnecessary, and in the present embodiment, such a portion is arranged along the L-shaped seam so that one skin piece 1 It is cut at the same time when cutting. The headrest skin thus configured is also easy to sew an L-shaped seam using the notch 19 as a guide, so that the sewing is facilitated. 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 skin piece 1, the other skin piece 2, fold 1
1, the shape and size of the slit 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 comprises only two skin pieces, which contributes to shortening of cutting and sewing work time, and furthermore, the number of seam lines is reduced. Together with this, it has an excellent effect on improving the appearance of the headrest.
