Wheelchair Parts: The Freedom Of Mobility, Fixed Up

By Andrew Kelly

A wheelchair is a wheeled mobility device in which the user sits. The device is propelled either manually, by pushing the wheels with the hands, or via various automated systems. Wheelchairs are used by people for whom walking is difficult or impossible due to illness, injury, or disability. People with both sitting and walking disability often need to use a wheel bench. A basic standard manual wheelchair incorporates a seat and back, two small front caster wheels and two large wheels, one on each side, and a foot rest.

Most wheelchairs are variations on this basic design, but there are many types of wheelchairs, and they are often highly customized for the individual user's needs. The seat size, seat to floor height, foot rest; leg rest, front caster outriggers, adjustable backrests, controls, and many other features can be customized on, or added to, many basic models, while some users, often those with specialized needs, may have wheelchairs custom built. Various optional accessories are available, such as anti tip bars or wheels, safety belts, adjustable backrests, tilt or recline features, extra support for limbs or neck, mounts or carrying devices for crutches, walkers or oxygen tanks, drink holders, and clothing protectors.

Experiments have also been made with unusual variant wheels, like the omni wheel or the mecanum wheel. These allow more directional movement options. The electric wheelchair shown on the right is fitted with Mecanum wheels, sometimes known as Ilon wheels, which give it complete freedom of movement. It can be driven forwards, backwards, sideways, and diagonally, and also turned round on the spot or turned around while moving, all operated from a simple joystick.

Power chairs use electric motors to move the wheels. They are usually powered by four or five amp deep cycle rechargeable batteries, similar to those used to power outboard boat engines. These are available in wet or dry options; most these days prefer dry cell batteries, and airlines will not allow the transport of wet batteries. Many power chairs carry an on board charger which can be plugged into a standard wall outlet. Older or more portable models may have a separate charger unit. To order parts for your wheel or power chair, simply talk to the person or persons you had customize your wheel chair or contact your local distributor through the internet.
