Abstract:
The present disclosure describes devices and systems that can be integrated with a foldable, manual wheelchair to convert the wheelchair into a hybrid chair capable of both manual operation and motor-powered operation. A wheelchair powering device includes a motor that is operatively coupled to a roller member so that rotation of the motor shaft causes rotation of the roller member. The roller member may be engaged against a tire of the wheelchair so that rotation of the roller member causes rotation of the tire via friction between the roller member and tire.

Claim (Index 8):
The wheelchair powering device of  claim 7 , wherein the roller member passes through a roller member bracket, and wherein the lever is operatively coupled to the roller member bracket such that adjustment of the lever causes rotation of the roller member bracket to displace the roller member.
