A hydraulically controlled seat adjuster mechanism for providing fore-and-aft adjustment in the position of a vehicle seat includes first and second hydraulic cylinders, which support the seat on the floor of the vehicle, the hydraulic cylinders being connected in a series hydraulic circuit with a control valve in a manually driven embodiment, and with a control valve and a pump and motor assembly in a power driven embodiment, the control valve being manually operable between a flow preventing condition to interrupt the hydraulic circuit in which the hydraulic cylinders are prevented from operating so that the seat is locked in position, and a flow permitting condition to complete the hydraulic circuit, permitting the hydraulic cylinders to operate and move the seat to an adjusted position. The hydraulic mechanism is also described with reference to an application for controlling the adjustment of the angle of inclination of the seat back relative to the seat cushion.
