  • Ergonomic productivity workstation having coordinated and harmonized movement of head rest, backrest, seat, leg rest, arm rests, monitor support, and work trays through sitting, standing, and reclining configurations
    Patent number: 9955785
    Abstract: An ergonomic workstation that includes a base; an effective hip axis affixed to the base; a seat bottom that rotates about the effective hip axis; a seat back that rotates about the effective hip axis; an effective shoulder axis positionally fixed to the seat back; an effective elbow axis positionally fixed to the seat back; a monitor support having a monitor mount that rotates about the shoulder axis; and an input device tray support configured such that an input device tray on the support rotates about the elbow axis. As the workstation moves through a broad range of operational zones, it maintains a fixed eye-to-monitor distance and fixed angle between the user's head and the monitor throughout a significant portion of the range of motion, and a fixed distance from the user's elbow to an input device throughout the entire range of motion.
