ABSTRACT:
A steerable, powered wheelchair with a mobile base, and two movable arms that are attached to a seat. The seat is attached to the arms with pivots that permit rotation of the seat in both vertical and horizontal planes. The arms can move through three positions. The first position is the at rest position. Here, the seat rests near or directly on the base. In the second position, the seat is spaced vertically above the mobile base. In the third position, the seat is extended forward of the mobile base 2 and can drop down to floor or ground level. A feature of the mobile base it that when the seat is in the third position, the mobile base can rotate vertically about the front wheels. This allows the wheelchair to run on two wheels, increasing the wheelchair's angular mobility. In this operational mode, the user can exercise his or her legs by bouncing them against the ground. Such bouncing while moving in a forward direction, can even simulate running or hopping, which helps exercise the user and offers an increased level of interaction and play for the user.
