Wheeled Chair Base

CUSTOM ADAPTATION PURPOSE: To adapt a positioning chair for an individual with cerebral palsy to provide mobility. A base plate made of 12 millimeter (mm) plywood with a rounded cutout to accommodate the user's legs for foot propulsion was created. The original chair legs were shortened and the angles were fastened with horizontal bolts screwed to the base. Braked casters with polyurethane tires were attached to the underside of the base. In a final step, armressts similar to those found on office chairs were added to the chair to provide arm support and aid in seated balance. DIMENSIONS (DxW): The base is 620 x 600 millimeters and the cutout is 200 x 360 millimeters. The chair sits 325 millimeters above the floor and the armrests are 210 millimeters above the seat. The wheels are 75 millimeters in diameter. TITLE: Wheeled Chair Base. JOURNAL: TAD Journal. REF: Volume 25, Number 1, Autumn 2005. P. 12. PAGES: 2 (including cover).
