Description

[Detailed Description of the Invention] Industrial Application Field This invention relates to a core material for a pocket provided on the side of an automobile seat or the like.

BACKGROUND ART FIG. 6 is a cross-sectional view of the vicinity of an open end 23 of a pocket 22 provided on the side of a conventional seat 21.
In No. 3, the core material 24 is covered and sewn by the covering portion 25a of the pocket member 25. That is, core material 2
4 is a strip-shaped core plate (thickness 1 mm) 26 with an elastic metal wire 2
7 is also fixed with an adhesive tape 28, and a urethane foam strip covering material (8 mm thick) 29 is further wrapped around this. According to this core material 24, not only is there a problem in terms of shape retention and restorability against external forces, but also the metal wire 27 lifts the covering material 29 and the covering part 25a, so that the end part 23 does not lose its shape. Otherwise, it became thick and ungainly and lacked design. In addition, when putting articles in and out of the pocket section 22, there is a drawback that the metal wire 27 is exposed through the covering material 29 and the enveloping section 25a, foreign objects, and discomfort may be felt.

Problems to be solved by the invention The invention aims to solve the disadvantages of core materials for pockets, such as shape retention and restorability, as well as poor design and discomfort caused by the core material at the opening end.

Measures to solve the problem Fix the elastic metal wire on the core plate with adhesive tape,
The same core plate as above is placed on top of the core plate, and the close peripheral edges of both core plates are hemmed and fixed with the tape to form an integral piece.

Function The core material is capable of withstanding external pressure that is repeatedly applied to it and reliably exhibits shape retention and restoration functions, and the opening end of the pocket using this core material will not lose its shape. There are no foreign objects or discomfort at all.

Embodiment An embodiment of this invention will be described in detail with reference to the illustrative diagrams of FIGS. 1 to 5.

Figure 1 is a partially cutaway plan view, Figure 2 is a sectional view taken along line A and A in Figure 1, Figure 3 is a side view, Figure 4 is a perspective view of the seat, Figure 5 is Figure 4C, It is a sectional view taken along line C.

In the figure, 1 is a core material for a pocket such as a seat, 2 is a core plate, 3 is a metal wire, 4 is an adhesive tape, 6 is a pocket portion, and 7 is an opening end portion.

The core material 1 of this invention consists of an elastic metal wire (diameter 3 mm) on a strip-shaped core plate (0.5 mm thick) made of semi-rigid synthetic resin.
3 was fixed with an adhesive tape 4, and a core plate 2 of the same shape as above was placed on top of it, and the close peripheral edges 2a of both core plates 2, 2 were hemmed and fixed with the tape 4 to form an integral piece. It is something. The metal wire 3
For example, a hard steel wire (SWB) is optimal, and both ends thereof may be straight, or may be bent into a bent shape 3a as shown in the figure. The adhesive tape 4 is preferably one that can withstand external force and does not peel off, and for example, the trade name Slion Tape is suitable.

In FIG. 5, the core material 1 of this invention is sewn over the opening end 7 of a pocket 6 provided on the side of the seat 5, etc., using the covering portion 8a of the pocket member 8. The end portion 7 can be repeatedly expanded (shown by a dashed line) and restored (shown by a solid line) when an article is put in or taken out of the pocket portion 6 or by external force from other free directions. It can withstand repeated use without deforming or sagging. This is because the core material 1 has remarkable shape retention and restoring functions. During the expansion, the elastic repulsive force of the metal wire 3 is transmitted to the hand, etc. via the core plate 2, but the hand, etc. does not feel any obvious, foreign material, or discomfort at all. Since this device is relatively thin, the opening end portion 7 can be finished beautifully and with an attractive design.

Effects of the invention As described above, this invention fixes a metal wire onto a core plate using adhesive tape, overlays the same core plate as above, and attaches the close peripheral edges of both core plates to the tape. Since the edges are fixed and integrated, all of the conventional drawbacks such as shape retention, restoration, design issues, as well as problems such as exposure, foreign matter, and discomfort can be solved, and its practical value is great.
