  The present invention is broadly divided into a seat plate 10 and a seat plate 20, and additionally, the seat plate 20 can be adjusted by the elastic force of the coil spring 30 and the rotation angle of the seat plate 20 by providing a cushion feeling. A stopper 40, a support plate 50 for maintaining the hinged state of the seat plate and the seat plate 10 and 20, and a spring support plate 60 for preventing the coil spring 30 from being detached are included. The armrests 70 attached to both sides of the seat plate 10 are formed so that the width and height can be adjusted simultaneously.

  The seat plate 10 as described above is injection molded in a substantially square plate shape with a synthetic resin material. Therefore, a complicated hinge structure manufactured by an existing welding method can be easily manufactured by an automated method.

  First and second hinge brackets 11 and 11-1 are integrally formed in four directions on the seat plate 10. The first hinge bracket 11 is divided into both sides when viewed from the front, and a pair of front and rear is arranged symmetrically with the second hinge bracket 11-1.

  The first and second hinge brackets 11 and 11-1 are arranged vertically on the seat plate 10 and are separated from each other at a predetermined interval. The first hinge bracket 11 is fastened with a hinge pin 21 formed integrally with the seat plate 20 from above, and is formed with a fastening groove 11a that is open upward, and the second hinge bracket 11- A fastening hole 11b is formed at the center of the plate 1.

  A through hole 12 is formed on the seat plate 10 in the vicinity of the first hinge bracket 11. A support 50 having a fastening hole 11c is inserted below the through hole 12. The fastening hole 11c is disposed so that the center thereof coincides with the fastening groove 11a and the fastening hole 11b of the first and second hinge brackets 11 and 11-1, so that the hinge pin 21 can be inserted at the time of coupling.

  A spring support groove 13 is formed inside the first and second hinge brackets 11 and 11-1 on the seat plate 10, and a coil spring 30 is coupled to the spring support groove 13.

  A hinge pin 21 and a spring support groove 22 that are coupled to the first and second hinge brackets 11 and the spring support groove 13 are integrally formed on the bottom surface of the seat plate 20.

  Here, the seat plate 20 is injection-molded with a synthetic resin material in the same manner as the seat plate 10. Further, a cushion member can be further provided on the upper surface of the seat plate 20 to form a cushion layer.

  The hinge pin 21 is penetrated through a central hole of a plate-like body projecting perpendicularly to the bottom surface of the seat plate 20. At this time, the hinge pin 21 is formed integrally with the plate-like body with one end being long and the other end being short with the plate-like body as the center. When coupled to the hinge bracket 11 of the seat plate 10, the long end of the hinge pin 21 is provided in the fastening groove 11 a and the tip is inserted into the fastening hole 11 c of the support 50.
