How about adjusting the back seat of the big dipper to a right angle?

There is a buckle at the left and right corners of the backrest. Just to mention.

Turn the adjustment button on the left side of the seat to adjust it according to your body, and tilt it by one or two sections at most. When adjusting, use the strength of the back to adjust the tilt angle of the back until the palm can press the upper end of the steering wheel.
