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 17):
The system of  claim 16 , further comprising a second wheelchair powering device, wherein the second wheelchair powering device includes\n an attachment mechanism that attaches the second powering device to the wheelchair; a motor; a roller member operatively coupled to the motor such that operation of the motor drives rotation of the roller member; and an adjustment mechanism operatively coupled to the roller member, the adjustment mechanism being configured to control movement of the roller member into and out of contact with a wheel of the wheelchair, wherein the second wheelchair powering device is configured to provide for the wheelchair to be folded with the both the first and second wheelchair powering devices integrated with the foldable wheelchair, wherein, upon integration of the first and second wheelchair powering devices with the wheelchair, the wheelchair is configured to be powered interchangeably by both operation by the first and second powering devices and manual operation, and wherein the first wheelchair powering device is adapted for attachment to a first side of the wheelchair and the second wheelchair powering device is adapted for attachment to a second side of the wheelchair.
