[0006]
The seat back pad 12 is foamed integrally with the seat back frame 11 by opening ornament fitting holes 22, 22 on the left and right corresponding to the ornament brackets 11, 11, and the pad. Extensions 23, 23 are extended on the front and rear flanges 20, 21 of the ornament brackets 11, 11. The pad extensions 23 and 23 are where the thickness in the free state is set according to the tightening strength required to stop the skin 13.
[0007]
The left and right ornaments 14 and 14 are molded from resin and assembled with the ornament front 15 and the ornament rear 16 which are divided into two front and rear as shown in FIGS. The flange 24 where the ornamental front 15 projects to its front end is aligned with the back surface 17 of the seat back 10, while its flange 25 where the ornamental rear 16 projects to its rear end is the seat back. The back 10 of the back 10 is matched. Also, the ornament front 15 and the ornament rear 16 are brazed together, and are integrally coupled to each other by the pawl lock 28 to be assembled into the ornaments 14, 14.
[0008]
The pawl lock 28 is composed of hook stoppers 29, 29 and bifurcated claws 30, 30, and the hook stoppers 29, 29 are projected in an arch shape on the outer peripheral surface 26 of the ornament front 15, The bifurcated claws 30, 30 protrude from the outer peripheral surface 27 of the ornament rear 16, and extend in a cantilevered manner from the front end of the ornament rear 16 to the ornament front 15. In particular, the hanging stopper 29 is provided with tapered surfaces 31, 31 for guiding the bifurcated claws 30, 30, while the bifurcated claws 30, 30 braze the ornament front 15 to the ornament rear 16. Guide surfaces 32, 32 to be provided at the base.
[0009]
The seat back 10 described above is assembled as follows. Since the head restraint frame and the ornament brackets 11 and 11 are previously welded to the seat back frame, the seat back pad 12 is first integrated with the seat back frame. Foamed.
