Abstract
An adjustable manual wheelchair handrim with a moveable elastomeric friction band. The position of the tubular handrim can be moved to a desired location relative to the wheel rim depending on the needs and limits of the user. The movable friction band is stretched around the drive surface of the handrim at a desired location preventing it from moving and providing increased frictional properties when gripped by the user during pushes. The friction band can be permanently affixed at a location to further prevent movement and slippage between the handrim and the friction band.
