Description

[Detailed Description of the Invention] (Industrial Field of Application) This invention relates to a suspension wire drawing device for a seat skin for covering the seat skin material of a vehicle seat along the shape of a seat pad.

(Prior art and its problems) Conventionally, this type of suspension structure for seat skin material has been disclosed in Japanese Utility Model Publication No. 59-38959, and the technical content disclosed in this publication is shown in Figures 8 and 9.
As shown in the figure, in a sheet S formed by suspending and binding the skin 1 to the seat pad 2 in order to form a seat surface 3 of a desired shape, the portion of the seat pad 2 where the skin 1 is suspended and bound, i.e. ,
A flexible band-like piece 5 made of a substance other than metal is embedded in the hollow forming part 4, and a hanging bag 6 attached to the skin 1 is attached to the band-like piece 5, and a resin locking pin having a bent locking piece 8 at the tip. 7.

In addition, as another conventional example, as shown in FIG. 10, a retractable wire 9 is integrally embedded in the recessed portion of the seat pad 2, and a groove 10 is formed from the seat surface 3 side to the vicinity of the retractable wire 9.
Further, a hanging bag 6 with a hanging wire 11 inserted therein is sewn to the skin 1 along the hollow molded area 4, and the hanging bag 6 is inserted into the groove 10 to connect the hanging wire 11 and the retractable wire 9 to the hog ring gun 12.
There is a configuration in which they are bound together by a substantially C-shaped hog ring.

However, in the case where the locking pin 7 is made of resin, the locking pin 7 is attached to the hanging bag 6 and the flexible strip 5.
It takes a lot of work to stick the locking piece 8 to the back side of the strip 5, and the binding work using hog rings causes variations in the binding depending on the operator. 6 into the groove 10, it is difficult to confirm the position of the lead-in wire 9, which may lead to tying errors, making the work difficult, and increasing the number of man-hours required for tying, so that it is necessary to rely on skilled workers. In addition, with the above configuration,
Since a resin locking pin 7 and a hog ring are required as binding members, there is a problem in that the number of man-hours for parts management becomes large.

Therefore, in order to solve the above conventional problems, the present applicant has developed a "sheet" that can be easily bound even by an unskilled person without requiring the resin locking pin 7 or hog ring as the binding member. We have previously filed an application for the Suspension Structure for Seat Cover Materials (Utility Application No. 1982-092501), and now we have further automated the hanging and tying of the suspension wires in this Suspension Structure for Seat Cover Materials.
