[0002]
[Background]
In recent recreational beagles and sports cars, seats tend to use netted seat backs. The seat back uses clips and garnish to cover the terminal of the epidermis and the frame edge by the epidermis, so that the processing is complicated, there are many parts, and the cost increases.
[0003]
[Problems of the Invention]
An object of the present invention is to provide a seat back that can reduce the number of parts to be assembled, simplify the terminal processing of the skin, easily hide the frame, finish smartly, and improve the appearance.
[0004]
[Means corresponding to the problem and its operation]
In the present invention, a main frame that maintains a seat back shape, a trim hook is disposed on the back side of the net, and an ear cloth of the trim hook is sewn to the net terminal, and the net terminal is attached to the net terminal with the frame hook. A net that forms a backrest surface in a tensioned state with the main frame, and a seat back that is assembled to the main frame by removing the meat corresponding to the backrest surface and opening the net window. The pad and the seat back pad are put on, and the net terminal is sewn on the surface of the net from the net terminal to wind the opening edge of the net window of the seat back pad, and the other Sew a long and thin resin plate on the skin terminal and wrap around the back and back edges of the seat back and pad. And an outer skin hooked to the main frame by hooking it to the trim hook, and then the net to the main frame with the frame hook and then the seat cushion pad to the main frame and net terminal And then trim the skin to the main frame by inserting the elongate resin plate into the trim hook so that the other end of the skin is caught in the trim hook.

[Explanation of specific examples]
Hereinafter, the seat back of the present invention will be described based on the specific examples shown and illustrated. FIGS. 1 to 3 are used for a front seat 30 in a light wagon that can also be used for a recreational beagle. An embodiment 10 of the seat back according to the present invention is shown, and the seat back 10 is supported on the seat cushion 31 by the left and right reclining devices (not shown) so as to be adjustable in angle, and the head back A restraint (not shown) is removably attached and assembled to the front seat 30.
[0006]
In the seat back 10, the main frame 11 is made into a Z-shaped magnesium frame with a lip and maintains the shape of the seat back 10, and the net 12 has a trim hook 22 on the net back surface 19 side. Is placed, the ear cloth 23 of the trim hook 22 is sewn to the net terminal 20, and the net terminal 20 is fixed to the main frame 11 with the frame hook 21 to form the back support surface 15 in a tension state. Further, the seat back pad 13 removes the portion of the meat corresponding to the back support surface 15 to open the net window 24 and is assembled to the main frame 11. Then, one of the skin terminals 27 is sewn on the net surface 18 from the net terminal. The seat back pad 13 is wound around the opening edge 25 of the net window 24, and an elongated resin plate 29 is sewn to the other skin terminal 28, and the back and back edges 26 of the seat back pad 13 are wound around. The elongated resin plate 29 is hooked on the trim hook 22 and fixed to the main frame 11.
[0007]
The net 12 is preliminarily stitched together with the ear hook 23 of the frame hook 21 and the trim hook 22 overlapped on the net terminal 20, and the front of the main frame 11 is secured with the frame hook 21. The elongate resin plate 29 can be inserted into the trim hook 22 by being hooked on the lip 16 and stopped.
[0008]
The seat cushion pad 13 is wrapped around the rear lip 17 of the main frame 11 at the back back end 26 and assembled to the outer periphery of the main frame 11 to cover the main frame 11.
[0009]
Therefore, the seat back 19 is first tensioned to the main frame 11 by the net 12 hooking the frame hook 21 to the front lip 16 of the main frame 11, and then the epidermis. 14 is previously sewn to the net surface 18 at one of the skin terminals, so that the skin 14 wraps around the opening edge 25 of the net window 24 of the seat back pad 13 and the seat back pad. 13 is put on. Then, the outer skin 14 wraps around the back and back ends 26 of the seat back pad 13 and hooks the elongated resin plate 29 into the trim hook 22 in an inserted state. As such, when the elongated resin plate 29 causes the trim hook 22 to be wound around the other skin terminal 28 and inserted into the trim hook 22, the skin 14 is stopped by the main frame 11. Then, the seat back 10 is assembled in the state shown in FIG.
[0010]
