[57] ABSTRACT

A work station for ergonometrically supporting a human operator in a seated position while the human operates equipment located on the work station. A chair (12) has a first portion (12b) contactable by a thigh of the seated operator and a second portion (12c) contactable by the operator's back. The chair (12) is rockable about a horizontal axis of a main pivot shaft (28). A carriage (14) is secured proximate the front edge of the first portion (126) of the chair (12). A surface for supporting an input device (16) and a surface for supporting a visual display device (18) are attached to the carriage (14). As the seated operator rocks about the horizontal axis of the shaft (28), the spatial distance between the surface for supporting an input device (16) and the seated operator remain essentially constant, as does the spatial distance between the surface for supporting the visual display (18) and the seated operator.
