Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field The present invention relates to a method of manufacturing a see-through headrest having a cavity substantially in the center of the main body.

BACKGROUND ART Conventionally, in manufacturing a see-through headrest having a gap in the center part, a skin material that covers the outer circumferential surface of a cushion body formed in a substantially square shape, a skin material that covers the inner circumferential surface, and a skin material that covers the front and rear sides of the cushion body are used. A headrest cover is formed by dividing the outer circumferential surface into left and right halves and sewing them together to form a headrest cover, and after attaching the cover to the foam material, the divided edges of the outer circumferential surface are sealed with a slide fastener. It has been proposed to do so (Utility Model Application Publication No. 58-34653). However, in the headrest manufactured in this manner, not only is it time-consuming to stitch the skin materials together, but the seams are located at each edge of the outer periphery and the inner periphery and are exposed in easily visible areas, which is unfavorable in terms of appearance.

DISCLOSURE OF THE INVENTION In view of the above-mentioned drawbacks, it is an object of the present invention to provide a method for manufacturing a sea-null headrest that can easily manufacture a good-looking headrest without exposing the seams of the cover to the outside of the headrest. , the purpose.

That is, in the method for manufacturing a see-through headrest according to the present invention, two skin materials cut in advance into a substantially mouth shape are stacked with their front sides facing each other, and only the outer peripheral edges are joined from the back side in advance, Thereafter, the headrest cover is formed by sequentially passing the joint end side into the opening of the skin material and inverting the skin material at the joint location,
A cushion body made of urethane foam or the like, which has been formed into a substantially square shape, is inserted into the cover from the opening edge side, and finally the opening edges of the cover are joined from the surface side.

Embodiments will now be described in detail with reference to the drawings.

In the illustrated embodiment, a case is shown in which a see-through type headrest having a gap a substantially in the center is manufactured.

This headrest is fabric acid 1. ) is manufactured by covering a cushion body C made of urethane foam or the like which has been integrally foam-molded with a stay B etc. in advance with a headrest force t<-A formed of a fabric such as a knitted fabric (see FIG. 1).

In manufacturing the headrest cover A, the headrest cover A is formed by sewing together two cloth skin materials 1, 1 which have been cut into a desired shape in advance. Each of the cloth upholstery materials 1.1 has an opening 1a, l corresponding to the gap of the headrest A approximately in the center thereof.
It has notches tb and tb that form insertion holes for the stay B and the opening edge, and is cut and formed to have an area that can cover the cushion body C even if the opening edge and the outer peripheral edge are joined later (see Fig. 2). reference). These two skin materials 1.1 have respective front sides 1c and l.
c are stacked facing each other, and the outer edge 1d,
Only the ld is sutured from the back side over the entire circumference except for the notches 1b and lb (see Fig. 3). After that, the opening edge 1e
, The cover A is formed into a hollow bag-like shape having a gap in the middle by sequentially passing the seam end side from le and inverting the skin materials 1 and 1 at the seam as a boundary (see Fig. 4 a). reference). In that case, the suture terminal side is headrest cover A.
Each front side 1 of the skin material 1.1 located inside and superimposed
c and lc are exposed to the outside (see Figure 4).

For the headrest cover A formed in this way,
It is inserted so as to accommodate a cushion body C such as urethane foam. The cushion body C is formed by foam-molding the stay B integrally into a substantially mouth shape in advance. First, insert the stay B into the cover A through the opening 1a of the cover A and the notch 1b.
After inserting the cushion body C from the inside into the insertion hole formed by .
e.

It can be joined by folding the le and sewing it from the front side. Furthermore, after the end edges 1e and 1e are sewn or welded so that they face each other without being folded back, the wire 2 is placed along the joint, and the wire 2 is stretched and fixed to form the joining terminal 3.
It is also possible to press-fit and embed the wire 2 into the cushion body C (see FIGS. 5a and 5b). As the wire 2,
A cushion having a substantially quadrilateral shape that is larger than the inner circumference of the opening of the cushion body is used. Further, a groove 4 is formed in the portion of the cushion body C where the joint terminal 3 is embedded, and the joint terminal 3 can be positioned and arranged within the groove 4. The concave groove 4 can be formed to have a substantially dovetail groove shape that becomes wider toward the back, and the depth of the groove 4 is Jl+
By forming the bonding terminal 3 to be slightly shallower than the length of the bonding terminal 3, when the bonding terminal 3 is stretched and buried with the wire 2, the concave groove 4 can completely close the open end due to compressive deformation of the cushion body C. can. Therefore, in this case, the joining terminal 3
can be more securely inserted into the cushion body C, and the joints of the skin can also be tightly fixed.

In addition, when securing the unsewn edges 1e and le,
A molding 5 is fitted in advance into the groove 4 provided in the cushion body C, and each end edge Is, le of the skin 7 is attached to the molding 5.
It can also be fixed by inserting and fixing the tape 6.6 attached to it (see Fig. 6a and b). The tape 6 has one or more inverted edges 6a, 8b, is injection molded from thermoplastic or thermosetting plastic, and has edges 1e, 1 on the inner surface of the skin.
It can be attached to e by sewing or welding. The molding 5 is injection molded with thermoplastic or thermosetting plastic in the shape of a simple transverse groove, and has a partition plate 5a integrally molded inside the socket to partition the inside of the socket, and a tape 6. 6 upside down edge f3a,
Retaining edges 5b and 5c that engage with 6a are protrudingly molded. In addition to these retaining edges 5b and 5c, retaining edges 5d and 5e that engage with one of the inverted edges eb and eb provided on both sides of the tape 6.6 can be provided in the socket by protruding from the partition plate 5a. . The molding 5 may be integrally attached to the cushion body covered with the skin during foam molding, and the partition plate 5a may have a perfect circle or a semicircle on the tip side to hide the seam of the skin. bead edge 5
f can be integrally molded (see Fig. 6). It is preferable that the surface of the beaded edge 5f be embossed or the like to enhance its decorativeness.

In this case, the tape 6.6 is fitted into the molding 5 to fasten the inverted edges 8a, 8b to the edges 5b, 5c, 5d, 5e.
It is possible to join and secure the respective edges simply by meshing with the two ends. When inserting the tape 6, it is sufficient to insert one side at a time into each socket part separated by the central partition plate 5a, and even if one side is set and the other side is pulled, it will not come out or shift and will remain tightly fixed. can do. Therefore, the fitting work can be carried out extremely efficiently, and since the tape 6 is pressed and supported by the partition plate 5a after the tape 6 is fitted, the inverted edge 8a,
8b and retaining edge 5b.

5c, 5d, and 5e, it is possible to completely prevent the tape 6 from coming off.

Furthermore, each edge 1e of the skin is placed in a receiving molding 7 in the form of a simple transverse groove that is fitted in advance into the groove 4 provided in the cushion body C or is integrally attached to the cushion body during foam molding.
, le may be kept in shape by overlapping and folding to form a concave shape, and each edge Is, le may be fixed by fitting and attaching a presser molding 8 into the concave portion of the edge of the skin. Yes (see Figure 7). This presser molding 8 is formed in the shape of a horizontally long belt, and includes a head part 8a that bulges out from the part that fits into the recess in the end of the skin, and stoppers 8b that are integrally molded to protrude at regular intervals from the lower surface. We are prepared. The head 8a is positioned to cover the recess of the skin end, and the stopper 8b is inserted through the overlapping skin ends in the receiving molding 7, and further through the receiving molding 7, and its tip is connected to the cushion body C. is inserted inside.

In this case, the respective edges are assembled in a concave shape and fastened with the dowels 8b, and the parts where the combination is fastened are hidden by the presser molding 8 so that they are not exposed to the outside.

In headrests manufactured in this way.

At least the outer peripheral edge side of the headrest cover can be joined in advance and positioned within the cover, and the opening edge 1e
, 1e are also located within the circumferential side of the gap without being exposed to the outside of the cover, so that it can be made to have a good appearance.

Effects of the Invention As described above, according to the method for manufacturing a see-through headrest according to the present invention, a headrest with good appearance can be manufactured with simple operations.
