A multi-position examination chair for supporting a patient and assuming sequentially a plurality of obstetric and gynecologic examination positions includes a base. A chair mounted on the base includes a back portion pivotally attached to the base and a seat portion pivotally attached to the back portion. A first linear actuator pivotally moves the back portion into a desired position relative the base, and a linkage cooperates to cause a predetermined amount of pivotal movement of the seat portion relative to the base in response to pivotal movement of the back portion. A second linear actuator power means pivotally moves the seat portion into a desired position relative the back portion. Actuation of one of a plurality of switches cooperates with a control system for movement of the back and seat portions from one of the examination positions to at least a next following one of the positions within the sequence.

The chair includes a plurality of movable chair portions which are movable with respect to each other. An hydraulic power arrangement is provided for moving each of the chair portions into desired relative positions such that the plurality of examination positions may be achieved. A plurality of switch means are provided, with each such switch means associated with a respective one of the examination positions. A control means is responsive to the plurality of switch means for controlling operation of the hydraulic power arrangement. Actuation of each of the switch means results in the chair portions moving into the examination position associated with the actuated switch means. The switch means may include a plurality of foot-actuated electrical switches.
