Description

[Detailed explanation of the idea] The present invention relates to a vehicle seat.

For vehicle seats, for example, the first
As shown in FIGS. 1 and 2, a belt 3 in a predetermined pattern is sewn onto the skin portion 2 of a seat 1.

Conventionally, as shown in FIG. 3, the method for attaching the belt 3 is to use a skin part (so-called seat cover assembly) 2 consisting of a skin 4, a thin elastic material 5 such as urethane, and a backing fabric 6.
A belt 3 made of vinyl laser, fabric, etc. is sewn onto the top surface of the skin, and a pair of hanging cloths are sewn onto the back surface of the skin 2 so as to correspond to both sides of the belt 30. a
, 7b are sewn in, and the trim wires 8 inserted into the free ends of the hanging cloths 7a, 7b are attached to the seat frame while the hanging cloths 7a, 7b are pulled toward the frame side through the seat batt (not shown) under the skin part 2. Alternatively, it is fixed to the seat spring via a wire crimp.

However, as mentioned above, a seat with a belt that has a conventional design pattern requires a large number of parts such as the belt 3, a pair of hanging cloths 7a, 7b, and rim wires 8, and requires a large number of assembly steps. Also, since the S-thin sewing thread used to sew the belt 3 comes out to the surface, the viscosity of straight stitching is required, which inevitably increases the cost.

In view of the above points, the present invention provides a vehicle seat having a design pattern that improves marketability, reduces the number of parts and assembly man-hours, and reduces costs.

Hereinafter, the vehicle seat of the present invention will be explained using the drawings.

In the present invention, a specially shaped resin molded body 10 as shown in FIG. 4, for example, is provided.

This resin molded body 10 has a belt part 11 that forms the design pattern of the seat, seam allowances 12 extending horizontally on both sides of the belt part 11, and a hanging part 13 extending vertically downward at the center of the back surface of the belt part 11. It is formed into a long belt-like shape with a substantially T-shaped cross section.

The hanging portion 13 has an enlarged portion 14 at its tip.

The surface of the belt portion 11 can be further patterned with a predetermined pattern by means of grooves 15, etc., and on the back side of the border between the belt portion 11 and the outside seam allowance 12, there is a groove to facilitate the bending of the outside seam allowance 12. A concave groove 16 is provided.

When attaching a design pattern using a belt to the outer skin of a seat, first, as shown in FIG. Outer skin part 2 consisting of outer skin 4, thin elastic material 5 and lining fabric 6
are sewn together in a so-called bag stitch, and then as shown in Fig. 5H.
As shown in Figure 2, the outer skin part 2 is folded back from the seam part so that the outer skin 4 faces the surface.

At this time, the outer seam allowance 12 of the resin molded body 10 is bent in the groove 16, and the outer skin 4 and the surface of the belt portion 11 forming the design pattern are exposed to one side.

In this state, the hanging portion 13 of the resin molded body 10 is held on the frame side.

That is, the hanging portion 13 (not shown) is pulled toward the frame side through the seat band under the skin portion 2, and the enlarged portion 14 at the tip thereof is fixed to the seat frame or seat spring via a wire ring or the like.

In this way, a design pattern as shown in FIGS. 1 and 2 is formed on the skin portion 2 of the seat by the resin-molded belt portion 11.

6 and 1 show other embodiments of the present invention.

In this example, the resin molded body 10 is formed so that its seam allowance portion 12 is one step lower than the surface of the belt portion 11, and the seam allowance portion 12 is sewn to the outer skin portion 2 without bending. be.

Note that the hanging portion 13 is provided with punched holes 17 at predetermined intervals, thereby making it possible to impart flexibility to the hanging portion 13 itself.

According to the present invention described above, the resin molded body 10 that integrates the belt portion 11 and the hanging portion 13 is provided, and this resin molded body 10 is attached to the outer skin of the seat, so that a belt with a design pattern is formed. It is extremely easy to attach to the skin.

In particular, in this resin molded body 10, the hanging portion 13 and the enlarged portion 14 at its tip function as the conventional hanging cloth and trim wire, respectively, so that the hanging cloth, trim wire, etc. are omitted compared to the conventional case. This reduces the number of parts.

In addition, in the past, in consideration of the loosening of the belt and outer skin, two hanging cloths were sewn and fixed via trim wires, as shown in Figure 3, but in the present invention, one Since the belt portion 11 is held in place by the hanging portion 13, the number of parts is reduced and the number of assembly steps is also greatly reduced, thereby reducing costs.

Furthermore, when sewing the outer skin part 2 and the seam allowance part 12, so-called bag stitching is possible, so the sewing thread of the sewing machine is hidden.
For this reason, strict stitching accuracy is not required, improving workability and improving the quality of the product.
