The invention relates to the technical field of seats, in particular to a seat backrest and an adjustable seat. The seat backrest comprises a backrest body, an electric push rod, a control switch anda pressure sensor. The electric push rod is arranged in the backrest body, and the movable end of the electric push rod can extend out in the width direction of the backrest body so that the side, facing a driver, of the backrest body can protrude outwards. The pressure sensor is embedded in the backrest main body so as to detect the pressure of a driver acting on the backrest main body; the signal output end of the pressure sensor is electrically connected with the signal input end of the control switch, and the signal output end of the control switch is electrically connected with the electric push rod; when the pressure sensor detects pressure exerted on the backrest body by a driver, an electric signal can be output to the control switch, the control switch is closed, the electric pushrod is powered on and started accordingly, the movable end of the electric push rod stretches out by the preset length, the shape of the backrest body is adjusted accordingly, and the requirements ofthe driver are met.

    本申请涉及座椅技术领域,尤其是涉及一种座椅靠背及可调座椅。座椅靠背包括靠背主体、电推杆、控制开关和压力传感器。电推杆设置于靠背主体内,电推杆的活动端能够沿靠背主体的宽度方向伸出,以使靠背主体朝向驾驶员的一侧向外突出;压力传感器嵌设于靠背主体上,以检测驾驶员作用于靠背主体上的压力;压力传感器的信号输出端与控制开关的信号输入端电连接,控制开关的信号输出端与电推杆电连接;当压力传感器检测出驾驶员作用于靠背主体上的压力时,能够向控制开关输出电信号,使控制开关闭合,从而使电推杆得电并启动,电推杆的活动端伸出预定长度,进而实现对靠背主体形状的调节,以满足驾驶员的需求。
