Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a wire inserted into a seat cushion pad of an automobile seat.

<Prior Art> As shown in FIG. 5, an automobile seat has raised parts 2 formed on both sides of a seat part 1 to hold the important parts of the seated person on both sides, and also has a cover for the seat part 1. Retractable part 3 to follow the shape of the seat cushion pad
The cover is being retracted to form a For this reason, the seat cushion pad has
A wire for shaping the raised portion 2 or a member equivalent thereto, and a wire for drawing the cover are inserted.

Conventionally, as shown in FIG. 6, a shaping wire 5 is provided with a convex curved portion 4 corresponding to the shape of the raised portions 8 on both sides of the seat cushion pad 7, and a retracting wire 6 for retracting the cover. As shown in FIG. Output wire 9
were welded to both sides of the seat frame 10.

<Problems to be solved by the invention> In the case of the prior art shown in FIG. 6 above, in order to insert the forming wire 5 and the drawing wire 6 into the seat cushion pad 7, Two sets of separate wires 5 and 6 are required to position each wire in a predetermined position in the mold in which the pad 7 is foam-molded. Also,
Due to the terminal processing of each of the wires 5 and 6, the ends of the wires 5 and 6 went all the way to the rear, giving the impression of a foreign body, making it unsuitable for sheets with a small width on the rear side of the cushion. The convex curved portion 4 is simply a single wire bent into an arc shape, and there is no reinforcing member at the bottom, so the bending is large.
Holdability is insufficient.

In the case of the prior art shown in FIG. 7, the only thing that is set in the foam mold of the seat cushion pad 7 is the retracting wire 6a, so it only needs to be set once.
Since the forming wire 9 is welded to the seat frame 10, the seat frame 10 becomes a reinforcing member and has good holding properties, but it is too rigid and the forming wire 9 cannot be bent appropriately, so foreign particles may There were problems in that it required the user to give a sense of comfort and to weld it to the seat frame 10.

<Means for solving the problems> In order to solve the above-mentioned conventional problems, the present invention has the following features:
Point the U-shaped shaping wire for shaping the raised portions on both sides of the seat cushion pad and the U-shaped retracting wire for pulling in the seat cushion cover in the same direction. They are combined with their phases shifted and then connected together with clips.
Both U-shaped extending portions of the shaping wire are formed with convex curved portions corresponding to the shapes of the raised portions on both sides of the seat cushion pad.

<Function> According to the present invention, the sheet cushion pad only needs to be set in the foaming mold once, and the strength of the convex curved portion of the forming wire increases as it is integrally connected with the drawing wire. This ensures appropriate deflection.

<Example> Hereinafter, an example of the present invention will be described based on FIGS. 1 to 4. Figures 1 and 2 are the first part of this invention.
This is an example. That is, 11 is a shaping wire, which has a substantially U-shape as shown in FIG. 2, and has a convex curved portion 12 bent at its extending portion 11a. 13 is a lead-in wire. This is also formed in a substantially U-shape. As shown in FIG.
and are combined with a phase shift in the same direction, and are connected to the forming wire 11 with a clip 14, and both ends of the drawing wire 13 and the terminal of the convex curved part 12 are connected with a clip 15 to be integrated. It is.

3 and 4 show a second embodiment of the present invention. In this case, as shown in FIG. 4, the drawing wire 13' is U-shaped with an extending portion 13a, and the shaping wire 11' is approximately U-shaped with a convex curved portion. 12 into a curved shape. Then, the forming wire 11' is combined with the drawing wire 13' in the same direction and out of phase, and is integrally connected to the extending portion 13a of the drawing wire 13' with clips 14 and 15, as shown in FIG. This is the finished product shown.

Since the present invention has the structure as described above, in any embodiment, the forming wires 11, 11'
The wires 13 and 13' are composed of two parts, and both wires 11 and 11'
and 13, 13' are assembled together with wires 14, 15, and the finished product is one piece.

Further, in the first embodiment, the convex curved portion 12 formed on the forming wire 11 is reinforced at the bottom by the extending portion 11a of the forming wire 11, and in the second embodiment, the bottom side is reinforced by the extending portion 11a of the forming wire 11. It is reinforced with the existing portion 13a and has improved holdability and appropriate flexure.

<Effects of the invention> As described above, according to the invention, the forming wire and the drawing wire are two parts at the time of molding, but in order to combine both wires with clips to make a finished product, the sheet The cushion pad only needs to be set in the foam mold once, which improves work efficiency, and the convex curved part of the forming wire is integrated with the drawing wire, increasing its rigidity and improving holdability. It has the advantage that it has an appropriate degree of deflection and eliminates the feeling of a foreign body.
