Description

[Detailed description of the invention]

[0001]

This invention relates to a vehicle seat,
More specifically, the present invention relates to a cushion pad structure for a vehicle seat in consideration of recycling.

[0002]

2. Description of the Related Art Conventionally, for example, a seat cushion 1 of this kind of vehicle seat has a seat frame 2 in which springs 3 are stretched vertically and horizontally as shown in FIGS. 6 and 7, and a cushion pad fitted in the seat frame 2. 4 and a seat cover 7 on which the cushion pad 4 is sewn. In the seat cushion 1, the seat cover 7 is suspended to form left and right decorative grooves 1a and front and rear decorative grooves 1b as shown in FIG. Therefore, a suspension groove 5 is recessed on the upper surface side of the cushion pad 4 along the pattern of the decorative grooves 1a and 1b, a suspension wire 6 is insert-molded along the suspension groove 5, and a seat cover is formed. 7 is a main seat piece 8a, 8b and side pieces 8c, 8
d is sewn into a predetermined bag shape, a hanging bag 9 is sewn to the sewn portion, a hanging wire 10 is inserted through the hanging bag 9, and the hanging bag 9 is hung. The hanging wire 10 and the predetermined portion of the hanging wire 6 are suspended and fixed by hog ring,
The edge portions of the main seat piece 8b and the side pieces 8c, 8d are drawn into the lower surface of the seat frame 2 and fastened to the frame 2 to form the seat cushion 1.

[0003]

However, according to the structure of the conventional seat cushion 1, when the seat cushion 1 of a scrapped vehicle or the like is disassembled for each material for recycling, the wire 6 suspended on the cushion pad 4 is not used.
Is formed by insert molding, so that there is a problem that it is extremely difficult to take out the hanging wire 6 and it takes time and effort.

The present invention has been made to solve the above-mentioned conventional problems, and an object of the present invention is to provide a cushion pad structure capable of easily disassembling a hanging wire when recycling a seat cushion. It is assumed that.

[0005]

According to the present invention, in order to solve the above-mentioned problems, a sewing groove for hanging a sewn portion of a seat cover on the surface side of a cushion pad to form a decorative groove having a predetermined pattern is formed. Cushion pad for vehicle seats
In the structure, the suspension is provided on the back side of the cushion pad.
Substantially square wire fitting corresponding to the groove pattern
The groove is recessed, and a hanging wire is inserted into the wire fitting groove.
The ear can be fitted, the hanging wire,
Part of the wire is formed to be curved, and the wire fitting
When fitted in the groove, the inner surface of the wire fitting groove
Is characterized in that it is configured to be impacted in a biting manner .

[0006]

According to the present invention, therefore, the hanging wire is
It fits into the inner surface of the ear fitting groove by elastically engaging it
Seat cushion because of the so-called retrofit structure
From cushion pad for recycling
Can be easily performed.

[0007]

FIG. 1 is an exploded perspective view of a cushion pad 15 and a hanging wire 21 according to an embodiment of the present invention. As shown in FIG. 6, the seat cover 7 is suspended and the left and right decorative grooves 1a and the front and rear decorative grooves 1b are provided.
Are formed on the upper surface of the cushion pad 15 along the pattern of the decorative grooves 1a and 1b, and the seats are surrounded by the hanging grooves 16 and 17 in a substantially rectangular shape. A substantially rectangular wire fitting groove 19 is formed on the rear side of the recess 18 so as to correspond to the hanging grooves 16 and 17 having the same shape, and a rear convex portion 20 is formed. The hanging wire 21 is fitted into the wire fitting grooves 19 around the four circumferences of the rear projection 20 formed as described above.

The hanging wire 21 is formed by, for example, bending a steel wire or the like, and can be fitted into a wire fitting groove 19 formed on the four circumferences of the rear projection 20 of the cushion pad 15 as shown in FIG. The wire 21a of each piece has a plurality of members (in this example, two portions are formed on each wire) at the hanging position of the seat cover 7 in an upwardly U-shape. As shown in FIG. 4, each of the wire rods 21a is formed so that the center thereof is bent upward at a predetermined height L1 from both ends of the corners, for example, at a predetermined height L1. The hanging wire 21 thus formed is fitted in the wire fitting groove 19.

When the suspension wire 21 is inserted into the wire insertion groove 19, a substantially U-shaped locking projection 22 is formed on the wire 21a of each piece at the position where the seat cover 7 is suspended. At the same time, each wire 21a has a predetermined height L at the center from both ends of the corners.
As shown in FIG. 5 , when the wire is fitted into the wire fitting groove 19, the outer peripheral surface of the rear projection 20 , that is, the wire fitting groove 19 , as shown in FIG.
It is elastically attached to the inner surface of the body from four rounds. Further, each locking projection 22 presses the bottom side of the wire fitting groove 19 and is elastically attached to the bottom of the hanging grooves 16 and 17 in a biting manner in a state of being thinly approached. That is, in this embodiment,
A part of the suspension wire 19 is bent, and the bent portion
Form of retrofit to wire fitting groove 19
It is configured so that it can be fitted
You.

Therefore, since the hanging wire 21 is elastically attached in a biting manner around the rear projection 20 of the cushion pad 15, the hanging wire 21 does not fall off and does not hinder the covering with the seat cover 7. 1
The seat cushion can be formed by pulling and fixing the 0 and the locking projection 22 of the hanging wire 21 by hog ring.

As described above, in the cushion pad 15 of the present embodiment, it can be fitted in the wire fitting groove 19 on the back side formed in the pattern of the hanging grooves 16 and 17 on the surface side. Each of the wire rods 21a is formed with a plurality of locking projections 22 in a substantially U-shape upward at the position where the seat cover 7 is suspended. As shown in FIG. 4, the rear projections 21 a are formed so that the centers thereof are bent upward at a predetermined height L 1 from both ends of the corners as shown in FIG. Since it is configured so as to be bitten around, it does not fall off and does not hinder the covering with the seat cover 7 at all, so that the hanging wire 10 and the locking projection 22 of the hanging wire 21 can be connected. Hog When the seat cushion of a scrapped vehicle or the like is recycled, the suspension wire 21 is configured to be elastically attached, so that the disassembling operation can be easily performed. Can be. In addition, cushion pad 15
Since the suspension wire 21 is not insert-molded during the foam molding, the structure of the foaming mold is simplified, and the jig for setting the insert-molded suspension wire 21 is not required, so that the cost of the mold can be reduced. Having.

[0012]

Since the present invention is constructed as described above, when the hanging wire is inserted into the wire insertion groove, the hanging wire is formed in a biting manner around the rear convex portion surrounded by the wire insertion groove. It is possible to form the seat cushion by pulling and fixing the hanging wire and the locking projection of the hanging wire by hog ring without any trouble at the time of covering with the seat cover 7. In addition, when recycling a seat cushion of a scrapped vehicle or the like, the hanging wire is configured to be elastically attached, so that the disassembling operation can be easily performed. Also,
In the foam molding of the cushion pad 15, the hanging wire is not insert-molded, so that the structure of the foaming die is simplified, and the jig for setting the hanging wire in the insert molding is not required, so that the economy can be reduced in mold investment. Has the property.
