【Example】

 FIG. 1 shows a structure in which a buckle belt for a seat belt according to the present invention is installed in a rear seat cushion. In a seat cushion 10 thereof, a belt hole portion 11 has a seat cushion similar to that shown in FIG. It is formed near the center of 10 on the seat surface near the seat back. The belt hole portion 11 is formed in an inner shape having the same width or a slightly larger width so that the buckle belt 12 and the belt buckle 13 can be inserted therethrough.

The buckle belt 12 has one end connected and fixed to a seat frame or the like located on the lower side of the seat cushion 10, and the seat cushion of the seat cushion 10 is inserted from the lower side of the seat cushion 10 via a belt hole 11. It is equipped by pulling it out to the surface side. Further, a seat buckle 13 for hooking the hook side of the seat belt is attached to the buckle belt 12 in advance by connecting the seat buckle 13 to the end portion on the seat surface side.

In this buckle belt mounting structure, by mounting the support plate 14 that is elastically displaceable around the side portion of the belt hole portion 11, the belt insertion width a of the belt hole portion 11 can be at least equal to that of the belt buckle 13. It is configured to hold the bias narrower than the thickness b. As the support plate 14, as shown in FIG. 2, two plate members made of plastic or the like having rigidity are positioned inward so as to be elastically displaceable so that one end side is joined by sewing or the like. It can be used. Further, instead of the two plate members arranged oppositely, it is also possible to use, as shown in FIG. 3, a substantially U-shaped curved member that is elastically displaceable inward by plastic molding or the like. In order to mount the support plate 14, the support plate 14 may be attached around the side portion of the belt hole portion 11 provided on the skin material 10a forming the seat cushion 10 and fixed by sewing or the like. Further, the support plate 14 may be attached around the side portion inside the belt hole portion 11, or may be attached around the side portion of the belt hole portion 11 on the inner surface side of the skin material 10b in which the cushion pad 10b is housed. You can also

In the buckle belt equipment structure, the belt insertion width a of the belt hole portion 11 is urged and held by the support plate 14 to be narrower than at least the thickness b of the belt buckle 13, so that the inside of the belt hole portion 11 can be prevented. The width can be regulated so that the belt portion 12a extending from the belt portion of the buckle belt 12 located at the lower side of the seat cushion 10 does not rotate. Therefore, even if the equipped side of the belt buckle 13 is twisted, it can be prevented from being transmitted to the belt portion 12a of the buckle belt 12 extending to the lower side of the seat cushion 10. Further, since the belt insertion width a of the belt hole portion 12 is kept narrower than the thickness b of the belt buckle 13, it is possible to prevent the belt buckle 13 from falling into the belt hole portion 11. Furthermore, since the support plate 14 is mounted around the belt hole portion 11 so as to be elastically displaceable, the buckle belt 12 to which the belt buckle 13 is attached in advance can be easily inserted into the belt hole portion 11 and can be supported. Since the plate 14 has rigidity and holds the shape of the belt hole portion 11 and is not exposed to the outside from the belt hole portion 11, the appearance of the seat cushion surface side of the seat cushion 10 can be kept good.

The belt insertion width “a” of the belt hole portion 11 is biased and held by the support plate 14 so as to be substantially opposed to the belt thickness of the buckle belt 12, so that the belt portion 12 a of the buckle belt 12 can be sandwiched. It can also be set.

In this buckle belt equipment structure, in addition to the support plate 14, the latching projections 15 or 16 of the belt buckle 13 are provided along the upper edge of the support plate 14 as shown in FIGS. Can be equipped. As shown in FIG. 4, a bead 15 can be provided as a ridge for locking the belt buckle 13, and in this bead 15, the bead portion 15 a has a diameter larger than the thickness of the support plate 14. Functions to hook the belt buckle 13. Further, instead of the bead 15, a trim cord 16 having an arrowhead-shaped head portion 16a can be used, and the head portion 16a functions as a stopper for hooking the belt buckle 13. These ridges 15 or 16 can be attached along the upper edge of the support plate 14 by sewing the tape portions 15b and 16b together when the support plate 14 is attached to the edge.
