ABSTRACT:
An ergonomic seating system apparatus includes a linear alignment member, an interconnected seating device, such as a chair, and an adjustable footrest in combination with a work station. Preferably, the work station is fixed. The positions of the footrest and the chair are adjustable along a linear path by motor driven lead screws. The footrest includes a pair of drive motors which independently adjust the height of the front and rear of the footrest thereby facilitating adjustment of both height and inclination. A stanchion receives and retains the chair in the selected linear position. The chair may be removed from the stanchion to permit motion about the work station. Height of the chair is also adjustable. The seating system thus maintains a human body properly positioned fully to the rear in the chair, maintains an angle of between 90 and 180 degrees between the calf and thigh of the operator and maintains the feet at an angle of between about 80 and 130 degrees to the calf, a condition determined to significantly reduce stress and fatigue. A method of positioning a human body in a low fatigue, seated position is also taught.
