Abstract: An apparatus for moving a wheelchair, the apparatus having a base including a drive motor drivingly connected to a drive wheel and a first forwardly extending lower arm member engageable with the wheelchair when the wheelchair is in the engageable position. The first lower arm member is operable between a lowered position in which the first lower arm member is disengaged from the wheelchair and a raised position in which the first lower arm engages the wheelchair. The first lower arm member has a first stop member whereby, when the first lower arm member is in the raised position and engages the wheelchair, and when the wheelchair is on a forwardly extending declined surface, the first stop member inhibits forward motion of the wheelchair.

An assembly of at least two wheelchairs, wherein the wheelchairs in a nested condition occupy considerably less space than in unnested condition, while upon being unnested, an unnested wheelchair is configured for receiving a person without manually adjusting the seat configuration of the wheelchair.
