Abstract:

The boundaries of maximum possible arm reach for tasks on vertical instrument racks were determined on a stratified sample of twenty subjects, when seated in a standard office chair. The limiting effects of 3-12 inch thick service shelves, varying in depth from 10 through 25 inches and in height from 27.9 to 30.1 inches, were measured together with optimum seat height and leg clearance. The 5th, 50th, and 95th percentile reach contours show that shelf depths greater than 10 inches decrease arm reach, the amount being dependent upon shelf height. Service shelf depth, when at the optimum of height of 28 inches, should not be much greater than 20 inches if 95 percent of the operators are to reach a vertical display beneath it.
