Abstract
A medical lift-assistance device including a bracket, a variable assist mechanism, a lifting arm, and a pad sub-assembly. The variable assist mechanism has a strut attached to the bracket, a height-adjustment feature, a first gear, a first axle, a first rotational axis extending along the first axle, a first rotational direction, a second gear, a second axle, a second rotational axis extending along the second axle, and a second rotational direction. The first gear is rotatably attached to the first axle and the second gear is rotatably attached to the second axle and engages the first gear. The strut applies a force to the height-adjustment feature capable of causing the first gear to rotate in the first rotational direction and the second gear and the lifting arm to rotate in the second rotational direction.
