<< First Embodiment >>
(About the outline configuration of the seat back cover 30)
First, the configuration of the seat back cover 30 according to the first embodiment of the present invention will be described with reference to FIGS. 1 to 3. In the following description, when each direction such as front-back, up-down, left-right, etc. is shown, it means each direction shown in each figure.

As shown in FIG. 1, the seat back cover 30 according to the present embodiment is configured as a skin material for covering the seat back 1 of an automobile seat. The seat back cover 30 has a structure in which a plurality of fabric cover pieces are sewn together in a bag shape. The seat back cover 30 is covered with the seat back 1 as follows.

That is, the seat back cover 30 wraps the metal seat back frame 10 that forms the framework of the seat back 1 with peripheral parts such as the urethane foam seat back pad 20 that forms the cushioning material. It is covered from above. As a result, the seat back cover 30 is put on the surface of the seat back 1 in a state where the seat back pad 20 is pressed against the seat back frame 10 to hold the position.

A recess 1A for securing a space at the knee tip of a rear seat occupant is formed on the back surface of the seat back 1. As shown in FIG. 2, the recess 1A is formed by pulling the covering portion 31 of the seat back cover 30 that covers the back and back surfaces of the seat back 1 toward the front side in the middle portion in the height direction.

Specifically, the covering portion 31 is pulled forward in a substantially square shape in a side view. Then, as shown in FIG. 3, the covering portion 31 is placed on the front side by the resin plate 32 sewn on the front surface thereof being bridged between the front surfaces of the left and right winding portions 21 of the seat back pad 20.

As a result, the resin plate 32 is held in a state in which the covering portion 31 is pulled in to the front side in a state of being supported from the rear side by each winding portion 21. Specifically, the resin plate 32 is in a state in which the region covered between the two winding portions 21 of the covering portion 31 is widely pulled forward in a plane shape over the entire area in the sheet width direction by joining with both vertical stitched portions S1. Hold on.

More specifically, the resin plate 32 is provided in a state in which both overhanging portions 32A are set in a set groove 21A formed on the front surface of both winding portions 21. As a result, the resin plate 32 is provided in a state of being positioned in the seat width direction and the height direction with respect to both winding portions 21. Each set groove 21A is formed in a size that allows the double overhanging portion 32A to be fitted in a state of being positioned in the sheet width direction and the height direction in accordance with the shape of the double overhanging portion 32A of the resin plate 32. Has been done.

The resin plate 32 is further provided in a state in which the front surface of both overhanging portions 32A faces the rear surface of the rear flange 11A of both side frames 11 in the front-rear direction by assembling to the both set grooves 21A. As a result, the resin plate 32 does not float between the both winding portions 21 and the both rear flanges 11A so as to push the both winding portions 21 to the rear side, and the both winding portions 21 and the both rear flanges 11A do not float. It is configured to be arranged so as to be sandwiched between and in the front-rear direction. As a result, the resin plate 32 is provided in a state of being positioned in the front-rear direction between both winding portions 21 and both rear side flanges 11A.
