A net window 24 is opened and assembled to the main frame 11, and furthermore, a skin 14 is put on the seat back pad 13 and the net surface 18 is formed from the net terminal.
One of the skin terminals 27 is sewn onto the opening edge 25 of the net window 24 of the seat back pad 13, and an elongated resin plate 29 is sewn to the other skin terminal 28, and the seat back pad 28 is sewn. The elongate resin plate 29 is hooked on the trim hook 22 and is fixed to the main frame 11 by wrapping around the back / back end 26 of the pad 13. [0007] The net 12 is previously stored in the net terminal 2
0, sew together the ear cloth 23 of the frame hook 21 and the trim hook 22, and hook it on the front lip 16 of the main frame 11 with the frame hook 21, and The elongated resin plate 29 can be inserted into the trim hook 22. [0008] The seat cushion pad 13
The rear top end 26 of the main frame 11 is wrapped around the rear back end 26 and is attached to the outer periphery of the main frame 11 to cover the main frame 11. Therefore, the seat back 19 is
First, the net 12 is hooked on the front lip 16 of the main frame 11 with the frame hook 21 and is tensioned on the main frame 11;
Next, since the skin 14 is previously sewn to the net surface 18 at one of the skin terminals, the skin 14
Is the net window 24 of the seat back pad 13
Is wound over the seat back pad 13. Then, the skin 14 wraps around the back / back end 26 of the seat back pad 13 and hooks the elongated resin plate 29 into the trim hook 22 in a state of being inserted. As such, the elongated resin plate 29 is attached to the other
When the hook 22 is entangled and inserted into the trim hook 22, the skin 14 is attached to the main frame 1.
Stopped at 1. Then, the seat back 10
Are assembled in the state shown in FIG. As will be apparent from the specific embodiments of the present invention described above with reference to the drawings, for those having ordinary skill in the art to which the present invention pertains, the subject matter of the present invention will be described. , The nature of the invention (nat
ure) and essence (substance)
Then, they are easily embodied in another aspect that is objectively recognized as having them inherent. Of course, the content of this invention is
