Abstract
An hydraulic bath seat lift has a hydraulic cylinder assembly comprising an inner cylinder fixed with the floor and an outer cylinder, which can be raised and lowered by supplying hydraulic fluid to the assembly. The outer cylinder supports a seat at the end of a horizontal arm. The inner cylinder has a pin at its upper end projecting outwardly into one of two sets of longitudinal grooves along the inner surface of the outer cylinder to prevent the outer cylinder rotating relative to the inner cylinder. The grooves open into one another at the lower end of the outer cylinder so that when the outer cylinder is raised fully, to lift the seat above the bath, the cylinder can be rotated to swing the seat over the bath and then lowered with the pin engaging the other set of grooves.
