DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. Example 1. 1 is a perspective view showing a seat cushion 1 which is a seat portion of a vehicle seat according to a first embodiment of the present invention.
FIG. 3 is an enlarged cross-sectional view showing the fastening structure of the seat cover 3 taken along the line AA of the seat cushion 1 of FIG. The seat cushion 1 of the seat according to the first embodiment is configured by attaching a seat cover 3 to the surface of a mold pad 2 that forms the base of the seat cushion 1. Mold pad 2
As shown in FIG. 1, a decorative groove 4 having an appropriate depth is formed on the surface of the. An insert wire 5 is embedded along the groove bottom of the decorative groove 4.

The seat cover 3 covering the surface of the mold pad 2 is formed as a cover having a predetermined shape by sewing several cut cover cloths 7 and 8 lined with a cushion layer 6 having elasticity. ing. On the back surface of the seat cover 3, a hanging cloth 9 made of one piece of cloth is provided.
The sewing machine is sewn together with the sewing machine 8 and the sewing machine 8 at the one end side of the seat cover 3 by the sewing machine. The width of the hanging cloth 9 is shorter than the depth of the decorative groove 4, and the length of the hanging cloth 9 is about the same as the length of the sewn portion 8A of the cover cloth 7,8. In addition, the hanging cloth 9 can be formed to have a predetermined length necessary for retracting the seat cover 3. As shown in FIG. 3, a rod-shaped suspension rod 10 made of synthetic resin such as polypropylene or vinyl chloride is integrally fixed to the free end of the suspension cloth 9 as shown in FIG. A rib 11 having a semicircular or rectangular cross section made of a synthetic resin such as polypropylene or vinyl chloride is provided on both sides of the cloth of the hanging cloth 9 at a position near the hanging bar 10 of the hanging cloth 9 substantially parallel to the hanging bar 10. It is formed integrally on both sides so that it can be sandwiched between the two.

In the seat cover 3 having the above structure, the hanging cloth 9 provided on the sewn portion 8A is inserted into the decorative groove 4 of the mold pad 2 as shown in FIG. 1, and the insert provided on the bottom of the decorative groove 4 is inserted. The wire 5 is attached to the surface of the mold pad 2 by connecting the hanging rod 10 at the edge of the hanging cloth 9 to the wire 5 at several points as shown in FIG. The surface portion of the seat cover 3 to which the hanging cloth 9 is attached is pulled into the decorative groove 4 of the mold pad 2, and the other portion is brought into close contact with the surface of the mold pad 2.

Bending rigidity equivalent to that of a suspension wire cannot be obtained only by the suspension rod 10 made of resin, and the tensile load is concentrated at the portion connected by the C ring 12, and only the portion of the seat cover 3 corresponding to that portion is pulled in. As a result, the other portions tend to be loosened and have a swelling as a whole. However, in the first embodiment, the ribs 11 on both sides provided close to the suspension rod 10 are provided on the suspension rod 10. Since the lack of bending rigidity is supplemented, the bending rigidity of this portion as a whole is high enough to correspond to that of a suspension wire. That is, although the seat cover 3 is strongly pulled in by the C-ring 12 at the joined portion, the rib 11 restricts and uniforms the variation in the strength of the pull-in, so that the surface of the seat cover 3 is loosened and the appearance is greatly impaired. Swells etc. will not occur. Therefore, the function of the seat cover fastening structure including the hanging cloth 9 made of one piece of cloth and the hanging bar 10 made of resin can be enhanced without complicating the structure.

Example 2. FIG. 4 is a sectional view showing the main part of the seat cushion of the second embodiment.

Are connected to each other, and the relevant portion is configured to have a substantially I-shaped cross-sectional shape. As a result, the bending rigidity of the suspension rod 10, the rib 11 and the connecting portion 13 is sufficiently increased, and the connecting portion by the C ring 12 is reinforced by the connecting portion 13 so that the durability of this portion is also improved. The other configurations and functions are the same as those of the first embodiment, and therefore their description is omitted.

The number of ribs 11 may be selected in consideration of the bending rigidity in consideration of molding convenience. The suspension rod 10, the rib 11 and the connecting portion 13 are the same as those in the first and second embodiments.
Both of them can be continuously formed by extrusion, and productivity is obtained by forming a hanging cloth 9 by cutting a long base cloth extruded with the suspension rod 10, the rib 11 and the connecting portion 13 into a required size. Can be improved. Of course, the edge of the hanging cloth 9 may be inserted into the hanging rod 10 to form the hanging rod 10, and the rib 11 may be fixed to the hanging cloth 9 with an adhesive. The suspension rod 10 and the rib 11 are not limited to the synthetic resin, and may be made of metal, and the structure including the suspension rod 10, the rib 11 and the connecting portion 13 is preliminarily divided into two articles and no caulking. It may be attached to the hanging cloth by.
