Freedom Chair Parking Brakes: The Unique Value

Freedom Chair Parking Brakes: The Unique Value

Regular wheelchair parking brakes work well in perfect environments but can have some real challenges in tough environments. This is because many parking brakes rely on linkage mechanisms to maintain wheel compression. Linkages are a great solution to this problem, but they introduce many points of failure: every hinge in the linkage can loosen, tighten, wear out, or require maintenance.

When we created the Leveraged Freedom Chair (LFC)- specifically designed for disabled individuals in developing countries - we used a footrest inspired by the Whirlwind Roughrider. We designed it with a toe-guard in front, to keep the rider's feet from hitting the front wheel or obstacles in their path. It's adjustable up and down, but the process requires hand tools and is usually only done once per rider. When we redesigned the Freedom Chair for the US market, we wanted to use the LFC footrest as a starting point, but to make something even better.

I remember when the Freedom Chair was a brainstorming session on a whiteboard, in a long-neglected building in the northwest corner of the MIT campus, in a room we affectionately called the "MIT Mobility Lab." We were trying to reinvent the wheelchair, to design something that could help people with disabilities travel long distances outdoors, over rough terrain and pavement, and then move around indoors when they got to their destinations.
