Third, the entire back and the head are close to the inner wall of the elevator, in a straight line.
Fourth, the knee is in a curved posture. Explanation: Because I don't know when it will land, and it is likely to die when I fall.
the reason:
The first point is that when the emergency power is turned on, the elevator can stop immediately and continue to fall.
The second point is to fix your position so that you don't fall because of the unstable center of gravity.
The third point is to use the elevator wall as the protection of the spine.
The fourth point is that the most important thing is that the ligament is the only tissue in which the body is rich in elasticity, so the knee bending is used to withstand the pressure of the heavy shock, which is greater than the pressure of the bone.
