Abstract
A sofa waist propping device includes a frame and a waist adjusting mechanism, the frame being fixed on a sofa or a seat, the waist adjusting mechanism comprising a backrest and a first driving member rotatably connected to the frame respectively, the first driving member being rotatably connected to the backrest and driving the backrest to rotate around the frame. Since the first driving member is rotatably connected to the backrest and drives the backrest to rotate around a fixing member, the position of the backrest is adjusted, with a structure simple and stable and comfortableness increased.
