The T-bar is a T-shaped bar that connects the two calves to the seat plate through a control rod (see Figure 3). It can adjust the length of the thigh.
3.8 Control rod
The control rod is a component that fixes the seat plate and the T-bar longitudinal arm (see Figure 3). 3.9 Back angle (back angle)
The back angle is the angle of forward or backward tilt of the trunk bar relative to the plumb line. 3.10 Hip angle (hip angle)
