Wheelchair traction devices and systems

A wheelchair wheel traction system, the system comprising:

• two or more wheelchair traction attachments devices, each of the devices comprising:
• a frame having an arcuately-shaped longitudinal axis, an inner surface, an outer surface opposite and spaced apart from the inner surface, a first edge extending between the inner and outer surfaces, and a second edge spaced apart from the first edge, wherein at least a portion of the inner surface defines a channel;
• at least one first wheel-clip extending radially inwardly from the first edge of the frame relative to the arcuately-shaped longitudinal axis;
• at least one second wheel-clip extending radially inwardly from the second edge of the frame relative to the arcuately-shaped longitudinal axis;
• and
• a traction portion disposed along at least a portion of the outer surface, the traction portion extending radially outwardly from the outer surface relative to the arcuately-shaped longitudinal axis,
• wherein the channel is sized such that at least a portion of a wheelchair wheel is disposable within the channel, and the at least one first wheel clip and the at least one second wheel clip are positioned to removably couple the wheelchair wheel to the frame when the wheelchair wheel is disposed within the channel, and
• wherein the frame has a degree of curvature as measured from the first end to the second end in a plane that includes the longitudinal axis that is less than 180 degrees such that two or more of the frames are couplable to the same wheelchair wheel.
