Medical support apparatus
First Claim
1. A person support apparatus comprising:
- a base;
a seat supported on the base;
a backrest pivotable to different angular orientations with respect to the base;
a leg rest extendible and retractable to different positions with respect to the seat;
a controller for moving the person support apparatus from a first state to a second state, the first state being defined by a first orientation of the backrest and a first position of the leg rest, and the second state being defined by a second orientation of the backrest and a second position of the leg rest;
a control panel in communication with the controller;
a first control on the control panel having a first icon at or near the first control, the first control causing, when pressed, the controller to move the person support apparatus to the first state;
a second control on the control panel having a second icon at or near the second control, the second control causing, when pressed, the controller to move the person support apparatus to the second state; and
at least three discrete lights arranged in a line on the control panel, a first one of the lights operably associated with the first state and positioned adjacent the first control;
a second one of the lights operably associated with the second state and positioned adjacent the second control; and
a third one of the lights positioned between the first and second lights;
wherein the controller illuminates the first light when the person support apparatus is in the first state, illuminates the second light when the person support apparatus is in the second state, and illuminates the third light when the person support apparatus is in an intermediate state between the first and second states.

Abstract
A chair includes a seat, a backrest, and a leg rest. A tilt actuator and lift actuator tilt and lift the seat, respectively. A leg rest actuator extends and retracts the leg rest. A backrest actuator pivots the backrest with respect to the seat. A controller simultaneously controls the actuators such that they move sequentially between multiple predefined states. A control panel enables a user to automatically move the chair to any of the predefined states. Progress indicators are included that provide a visual indication of how far the chair has progressed to a commanded state. A controller controls the actuators such that they simultaneously arrive at each state. One or more functions on a control panel may also be automatically disabled and/or automatically enabled as the chair moves into or out of certain ones of the predefined states.
