the wheelchair

Every detail of our wheelchair design accounts for the developing world environment for which it was made.
To effect any lasting change in the developing world your product must integrate the following elements: Cost, Quality, and Sustainability. Our wheelchair accounts for all of them.



X-brace
The function of the X-brace is to collapse the wheelchair so that it takes up less volume for storage and travel. Functionally, the X-brace supports and aligns the two sides of the wheelchair and distributes the forces to its structural members. Our unique design collapses the chair over 1/3rd of its width without compromising strength and at a minimal added cost.


Footrest
The footrests have been designed to support the users’ legs and lower body while using the chair. In order to fully accommodate the needs of multiple disabilities the footrest position can be easily adjusted to maximize support. This design allows for the frame to collapse using an inexpensive and highly durable system.


Tires
The terrain in the developing world is rugged and the infrastructure is not accommodating for conventional wheelchair tires. Mountain bike tires are ideal for this environment. Conventional wheelchair wheels have significantly less contact area than mountain bike tires and often little or no tread. Conventional wheels are more likely to get stuck, prematurely wear, and can even endanger the user. In addition to the improved safety and functionality benefits, the tires allow for an air filled ride by absorbing significantly more shock than conventional tires.

 

 

Casters
The caster assemblies are an integral component of the wheelchair and serve multiple functions. The primary function of the casters is to distribute the force exerted on the front of the chair to the ground without compromising the wheelchair’s ability to turn. Our casters are capable of rotating 360 degrees in a smooth, uniform fashion under all user environments- while the chair is moving, stationary, and under considerable force. Furthermore our casters are unique in that their height can be adjusted to customize the angle of inclination of the seat. Integrating this angle adjustment feature allows IMI to further customize the wheelchair for specific end user needs.
