Dual mode wheelchair
Abstract:
A dual mode wheelchair (300) providing both a maneuverable indoor mode and a travel mode. The wheelchair (300) comprises fore wheels (104) mounted on a fore axis (105) and rear wheels (102) mounted on a rear axis (103). A distance between the fore axis (105) and the rear axis (103) defines a wheelbase of the wheelchair (300). The wheelbase is alterable between a short wheelbase providing a maneuverable mode of the wheelchair (300) and a long wheelbase providing a travel mode of the wheelchair (300). The wheelchair (300) further provides a lowered center of gravity and a reclining position in the travel mode to provide improved stability and occupant security.
