技术问题technical problem
当乘员乘坐在汽车座椅上需要向后躺时，目前主要利用靠背角度调节功能以实现向后躺的功能，部分座椅还可以实现在靠背向后倒时坐垫一起运动，例如坐垫上下移动、坐垫前后移动或坐垫与靠背之间相对转动。由于人体躯干为一个整体，无法跟随座椅一起运动，在靠背向后倒的过程中，靠背与坐垫之间产生相对运动，人体躯干需要调整姿态才能与调整后的座椅的形状和位置相匹配，从而影响乘员乘坐姿态的一致性，同时也对座椅乘坐的舒适性产生影响。When the occupant needs to lie back when sitting on the car seat, the backrest angle adjustment function is mainly used to realize the function of lying back. The seat cushion moves back and forth or relative rotation between the seat cushion and the backrest. Since the torso of the human body is a whole, it cannot move with the seat. When the backrest falls backwards, there is a relative movement between the backrest and the seat cushion. The posture of the human torso needs to be adjusted to match the shape and position of the adjusted seat. , thereby affecting the consistency of the occupant's sitting posture, and also affecting the comfort of the seat.
