Anthropometry of Wheeled Mobility Project: Final Report

This depicts knee and toe clearance required by manual chair users for forward approach to elements in the built environment (e.g., lavatories, drinking fountains). It references dimensions of clearance height and depth to the distal knee point on a person. Shaded areas depict the envelope of space required by the specified percentage of people if positioned with the distal knee point touching an obstruction. Hence, to accommodate a particular percentage of users, the side profile of a design element (shown by dotted line) should not extend outside the corresponding shaded area.
