An arbitrary angle K1 is placed on the circumference R1, R2,... with 10 as the center and the radius is changed.
, K2,..., base 3
It is engaged by a lever 5 on which there is a rotating shaft, the lever 5 being pulled in the direction of the shaft pin 10 by a return spring 12, said lever 5
Lever 4 with the same rotating shaft that can only be interlocked in one direction
This allows the user to put his/her weight on the base 3 and change the engagement position between the toothed portion of the base 3 and the lever 5, and the base 3 and the lever 5 are levers with different rotation axes. By pressing down on the lever 5, the engagement position between the base 3 and the lever 5 is fixed, allowing the user to repeatedly move the backrest to the selected angle.
