Abstract
Embodiments of the present disclosure include a wheelchair configured to reposition an occupant between a lowered and a raised position. The wheelchair can include a frame, a seat moveable relative to the frame, a drive wheel, and one or more pairs of arm assemblies. The arm assembly includes a wheel configured to move from a first spatial location when the wheel chair is operating on flat, level ground to a second spatial location that is different than the first spatial location. Arm limiters that can selectively engage the arm assembly dependent on the position of the arm assembly and surface conditions of ground and can limit the range of motion of the arm assembly and sometimes other operational aspects of the chair.
