The invention provides a rapid adjusting device of a seat backrest and the seat backrest, the rapid adjusting device comprises a driving gear, a driven gear, a generator, a transmission shaft and a stay wire, the driven gear is fixedly connected with a rotating shaft of a seat backrest framework to drive the seat backrest to rotate, the driving gear is sleeved on the transmission shaft, and the gear edge of the driving gear is overlapped with the gear edge of the driven gear; in the initial state, the driven gear and the driving gear are staggered in the direction of the transmission shaft, one end of the stay wire is fixedly connected and wound on a winding part arranged on the driving gear, the other end of the stay wire is connected with the generator, and the straightened part of the stay wire and the driving gear form an angle, and in the working state, the generator pulls the stay wire to enable the driving gear to rotate, and the stay wire is driven to rotate. And the driving gear is close to the driven gear along the direction of the transmission shaft so as to be meshed with the driven gear.
本发明提供了一种座椅靠背的快速调节装置及座椅靠背,包括驱动齿轮、从动齿轮、发生器、传动轴和拉线,从动齿轮与座椅靠背骨架的旋转轴固定连接以带动座椅靠背旋转,驱动齿轮套设在传动轴上,驱动齿轮与从动齿轮的齿轮边缘相交叠,初始状态下,从动齿轮与驱动齿轮在传动轴的方向上相互错开,拉线的一端固定连接并缠绕在设于驱动齿轮上的绕线部上,另一端与发生器相连并使拉线拉直的部分与驱动齿轮呈一角度,工作状态时,发生器拉动拉线以使得驱动齿轮转动,同时驱动齿轮沿传动轴的方向靠近从动齿轮以与从动齿轮相啮合。
