Description

[Detailed Description of the Invention] Technical Field The present invention relates to a method for joining the ends of the skin covering a cushion body so that the joined ends of the skin covering the cushion body are not exposed to the outside when manufacturing a headrest restraint, for example. It's about structure.

BACKGROUND TECHNOLOGY Conventionally, for example, when manufacturing a see-through type head restraint having a gap at approximately the center of the front surface (see Fig. 1 a and b), four pieces of skin material with dogleg-shaped notches on the left and right sides were each made. The doglegged edges are sewn together to form a skin 2 having a gap 1 in the center and an open outer periphery, and an open type slide fastener 3 is attached between the outer peripheries.
After the cushion body 4 is wrapped and housed in the skin 2, the open end of the outer periphery is closed with the slide fastener 3, and a metal molding 5 is attached as a garnish along the slide fastener 3 to hide the slide fastener 3. It is being done. However, in this headless restraint, the slide fasteners 3 or the metal moldings 5 are attached to simply join the outer peripheral edges of the skin, which is expensive and time-consuming to assemble. There is a risk that it will easily come off if it is only fixed with a hot spring bet.

DISCLOSURE OF THE INVENTION It is an object of the present invention to provide a joint structure between the ends of the skin that is easy to assemble, securely and stylishly hides each end of the skin.

That is, in the joint structure between the ends of the skin according to the present invention, each end of the skin is made to maintain its shape so that it exhibits a concave shape, and a presser molding is fitted into the recess, and at regular intervals protrudes from the lower surface. Each terminal is concealed by the presser molding by fixing the presser molding in the recess with a fixed pin.

Embodiment The following will be described with reference to FIGS. 2 to 4.

In the illustrated embodiment, a see-through type head restraint having a gap at approximately the center of the front face is manufactured.

In manufacturing this headless restraint, the cushion body (not shown) is foam-molded in a substantially square shape from the front, and the core bar (not shown) and the pillar 11 are formed during the foam-molding process. The cover material 12, 13, which can be attached integrally and can be wrapped in a cloth or vinyl chloride sheet, is preferably cut into a substantially rectangular shape and prepared in two pieces. The skin material 1
2 and 13 are made by facing each other and sewing or welding the inner periphery, and then passing one side through the central opening and turning it around at the joint, so that the inner edge is made with the front side facing outside. It can be formed as a single skin with the peripheral edge joints located on the inside and the outer peripheral edge left unjoined. The cushion body can be housed inside the skin by passing one side 12 or 13 of the skin through the central opening of the cushion body.

To join and close the outer periphery, each end of the outer skin is overlapped and folded into a receiving molding 14 located on the back side and having a generally groove-shaped cross section, thereby retaining its shape so as to form a concave shape. The receiving molding 14 is made of injection molded thermoplastic or thermosetting plastic, and can be joined to one end of the skin in advance by sewing or welding.
In addition, instead of this, reinforcing tapes 15 and 16 may be joined to the back side of the outer periphery by sewing or welding, so that the combination of the reinforcing tapes 15 and 16 can maintain a concave shape. can. These reinforcing tapes 15, 16 can be made of thermoplastic or thermosetting plastic by injection molding.
Among them, one side has two upper and lower sides 15a with a gap between them,
The reinforcing tape 16 on the other side can be inserted and held in the crocodile round shape by integrally molding 15b, so that they can be combined into a concave shape. Into the recesses of these skin ends, presser moldings 17, which are injection molded in the same manner as the receiving moldings 14 and reinforcing tapes 15 and 16, are fitted and attached. This presser molding 17 is formed in the shape of a horizontally long belt, and has a head 17a that bulges out from a portion that fits into a recess in the end of the skin, and retaining pins 17b that are integrally molded and protrude at regular intervals from the lower surface. We are prepared. The head 17a is positioned so as to cover the recess of the skin end, and the fixing pin 17b is inserted through the overlapping skin ends in the receiving molding 14 and is inserted into the receiving molding 14 or the reinforcing tape 15 combined in a concave shape. 16, they can be fastened to each other.

In the joint structure between the skin terminals configured in this way, the terminals are assembled in a concave shape and fixed with the fixing pin 17a, and the joint fixing point is hidden by the presser molding 17 so that it is not exposed to the outside. I have nothing to do.

In addition, the receiving molding 14 or the reinforcing tape 15,
16 can be positioned and fixed by providing a groove on the circumferential side of the cushion body and fitting the groove. Further, in the above-mentioned embodiment, the explanation was based on the case where the outer peripheral edge of the see-through headrest was joined.
This can also be applied to joining the inner peripheral edges.

Effects of the Invention As described above, according to the joint structure between the ends of the skin according to the present invention, the presser molding is fitted between each end of the skin which is kept in a concave shape, and the ends are fastened together with the fixing pin. To easily and surely join the ends of the skin without exposing the joints to the outside.
