Abstract
A wheelchair safety device transfers the weight of an entering or exiting user into a brake and stop against the rear wheel and floor, ensuring stability during the transfer. The device may be installed on one or both of the rear wheels of the wheelchair, and provides a handle which will bear the user's full weight with complete stability during the transfer. When not in use, the brake is disengaged, the floor stop is fully retracted to enable complete maneuverability of the wheelchair, and the handle also retracts.
