Abstract: A bath lift for lowering and raising invalids and disabled users into and out of a bath tub, having a frame with spaced opposite sides mounted on the bath tub. A shaft is rotatably mounted to each of the spaced opposite sides. A flexible cable is coupled to each of the shafts. The bath lift further includes a seat member having two sides and a rear. Each of the sides is coupled to one of the flexible cables, wherein rotation of either of the shafts effects a controlled movement of the corresponding side of the seat member. A back rest is pivotally connected to the rear of the seat member and is supported by the frame through a linkage. The linkage pivots the back rest as the seat member moves.
