Description

[Detailed description of the invention] Technical field The present invention relates to a joint structure between the edges of a skin covering a cushion body, which is applied to join the edges of a skin covering a cushion body, for example, in manufacturing a head restraint. It is.

BACKGROUND ART Conventionally, for example, when manufacturing a see-through type head restraint having a gap in the approximate center (see Fig. 1 a and b), four pieces of skin material each having a dogleg shape cut out on the left and right sides are used. A skin 2 having a gap 1 in the center and an open outer periphery is sewn by sewing the edges of the square shape to each other, and an open type slide fastener 3 is attached between the outer peripheries. After the cushion body 4 is enclosed and housed inside, 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 conceal the slide fastener 3. ing. However, in this head restraint, the slide fasteners 3 or the metal moldings 5 are simply sewn together between the outer peripheral edges of the skin, which is expensive and time-consuming to assemble. There is also a risk that it may easily come off because it is simply fixed with a hot rivet.

DISCLOSURE OF THE INVENTION It is an object of the present invention to provide an edge-to-edge joint structure of a skin that is easy to assemble and allows the edges to be joined in a secure and stylish manner.

That is, in the edge-to-edge joint structure according to the present invention, a tape with an inverted edge is attached along the edge of the skin, and the tape is attached to a molding with a generally groove-shaped cross section located on the inner surface of the skin. The end of the skin is fitted into the mold, and the tape is pressed and supported by a partition plate that divides the inside of the socket into left and right sides along the longitudinal direction of the mold, and the inverted edge of the tape is engaged and locked with the retaining edge that protrudes into the socket. It is constructed so that the edges can be firmly joined.
