Foreword
A motorized wheelchair, powerchair, electric wheelchair or electric-powered wheelchair (EPW) is a wheelchair that is propelled by means of an electric motor rather than manual power. Motorized wheelchairs are useful for those unable to propel a manual wheelchair or who may need to use a wheelchair for long distances or over terrain which would be fatiguing on a manual wheelchair. They may also be used not just by people with “traditional” mobility impairments, but also by people with cardiovascular and fatigue based conditions.
Objectives
To design a power wheelchair that assures the independence of the user so that he does not have to rely on anybody else.
To design a wheelchair that can provide a reclining facility for better comfort.
Performance requirements
Powerchairs require a reclining facility for users who are unable to maintain an upright seating position indefinitely.
The mechanism must allow full adjustment of the position of the backrest and leg rest.
The increments of adjustment must be less than 30 degrees for both.
Leg rests must be integrated into the seating.
Head rests to be adapted for users who need individually tailored support.
Powerchairs to feature a “standing” capability in which either the entire seat elevates to bring the user to standing height or just the seat-base.
It must be a rear-wheel drive equipped with a fully programmable and forward/ backward adjustable controller.
For users who are unable to use a hand controller, alternatives
