Embodiments of the present invention will be described below. First, a first embodiment shown in FIGS. 1 to 6 will be described. FIG. 1 is a perspective view showing a rear seat of an automobile.
The rear seat has an accessible structure in which the seat back 12 can be tilted forward with respect to the seat cushion 10. The back of the seat back 12 is used as luggage storage by folding the seat back 12 and stacking it on the seat cushion 10.

FIG. 2 is a plan view showing the back side of the seat back 12, and FIG. 3 is a sectional view taken along the line AA of FIG. The seat back 12 is roughly composed of a frame 14, pads 16 and a cover 18. The frame 14 is a hollow member having a predetermined rigidity and is formed by press molding of a metal plate or blow molding or injection molding of a resin material. The pad 1 is provided on the front side of the frame 14.
6 are provided, which are covered by the cover 18.

The cover 18 is formed in a bag shape so as to cover the central portion of the rear surface of the frame 14 except for the center portion thereof. I have. The string member 22 is inserted through the string passing portion 21, and the cover 18 can be tensioned by tightening both ends of the string member 22 with a so-called drawstring knot. Note that cutout portions 24 for partially exposing the string member 22 at the opening edge 20 of the cover 18 are formed at a plurality of locations of the string passing portion 21.

On the back surface of the frame 14, a step 30 whose outer periphery is lower at its outer periphery is continuously formed. Due to the step 30, a substantially vertical wall 31 is located on the frame 14 toward the outside, and the opening edge 20 of the cover 18 extends along the wall 31. Therefore, the opening edge 20 is positioned over the entire circumference by the wall 31. In addition, the step 30 includes a curved concave portion 34 that is recessed inward from the wall 31 at a plurality of locations corresponding to the cutout portion 24 formed on the opening edge 20 of the cover 18. That is, the bottom surface of each curved concave portion 34 is flush with the outer lower portion of the step 30.

FIG. 4 shows one curved recess 3 at the step 30.
FIG. 5 is a perspective view showing the device 4 together with other related members, and FIG. 5 is a plan view of FIG. As is clear from these drawings, a mounting hole 36 penetrating into and out of the frame 14 is formed on the bottom surface of the curved concave portion 34. A clip 37 can be attached to the attachment hole 36 by inserting its leg 38. The head 39 of the clip 37 fits into the curved recess 34.

In attaching the clip 37 to the mounting hole 36, the string member 22 exposed at the cutout portion 24 of the opening edge 20 is hooked on the leg 38 as shown in FIG. Is inserted into the mounting hole 36 as shown in FIG. As a result, the cut portion 24 is formed.
That is, the string member 22 exposed from the inside is pulled inward from the wall 31 of the step 30 and is hooked on the frame 14. By performing this operation at each cutout portion 24, that is, at each curved concave portion 34, the opening edge 20 (the string member 22) of the cover 18 is drawn along the wall 31 of the step 30.

As a result, the opening edge 20 is positioned over the entire circumference according to the planar shape of the wall 31, and especially the corner portion of the seat side is also positioned according to the set curve, and the design effect of the opening edge 20 is enhanced. Since the head 39 of the clip 37 is positioned so as to close the curved concave portion 34, the string member 22 hooked on the leg portion 38 is not easily detached, and the appearance of the curved concave portion 34 is improved.

FIG. 6 is a side view showing the rear seat in a state where the seat back 12 is tilted forward. As shown in this drawing, when the back surface of the seat back 12 is used as a luggage storage, the luggage 13 may be caught on the opening edge of the cover when the luggage 13 is placed or taken off with the conventional covering structure. However, in the present embodiment, since the opening edge 20 of the cover 18 is located on the lower side of the step 30, the opening edge 20 is substantially flush with the back surface of the frame 14, and the baggage 13 is less likely to be caught. Therefore, it is possible to prevent the handling of the load 13 from being hindered and the opening edge 20 to be peeled off by the load 13.

FIG. 7 is a plan view showing the second embodiment in correspondence with FIG. 5B. In the second embodiment, instead of the clip 37 of the first embodiment, a projection 40 is integrally formed on the bottom surface of the curved concave portion 34. The projection 40 has an opening edge 20.
The same function as that described above can also be obtained by hooking the string member 22 exposed at the cutout portion 24 of FIG.

Next, a third embodiment will be described with reference to FIGS. FIG. 8 is a plan view showing the back side of the seat back, and FIG. 9 is an enlarged cross-sectional view taken along line BB of FIG. In the third embodiment, the cover 18 is fixed to the lower side of the step 30 of the frame 14 at a plurality of locations along the opening edge 20 by a flat fastener 42. These planar fasteners 42 have a male fastener 42a bonded to the frame 14 side and a female fastener 42b sewn or bonded to the back surface of the cover 18. By fixing the frame 14 and the cover 18 with the flat fastener 42 in this manner, the opening edge 20 of the cover 18 is hardly turned up, and the curved concave portion 34, the mounting hole 36, or the projection 40 in the frame 14 are not required. The structure is simplified.

FIG. 10 is an explanatory view showing an example for connecting both ends of the string member 22. As shown in FIG. In FIG. 10 (a), a hook 44 is provided at one end of the string member 22, and a loop 45 is formed at the other end, and hooked and connected to each other. FIG.
In (b), hooks 44 are provided at both ends of the string member 22, loops 48 are formed at both ends of a rubber string 46 different from the string member 22, and the hooks 44 are hooked on the rings 48, respectively. The two ends of the string member 22 are connected via the intermediary. According to these connecting means, the work of connecting and tightening the string members 22 is simplified, and in the case of using the rubber string 46, the degree of tightening of the string members 22 can be easily adjusted by selecting the elongation characteristics.

While the preferred embodiment of the present invention has been described with reference to the drawings, this embodiment can be easily modified or modified without departing from the spirit of the present invention. For example, in the drawings, the covering structure of the seat back 12 has been described.
It can also be applied to zero or other sheet covering structures.
