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.

Claim (Index 1):
A powered wheelchair comprising:\n a frame; a drive wheel coupled to the frame and rotatable about a drive wheel axis; a drive configured to apply a torque to the drive wheel; a front wheel coupled to the frame, the front wheel being rotatable about a front wheel axis positioned forward of the drive wheel and translatable relative to the drive wheel axis; a rear wheel coupled to the frame, the rear wheel being rotatable about a rear wheel axis positioned rearward of the drive wheel and translatable relative to the drive wheel axis; and a limiter configured to restrict translation of the front wheel relative to the drive wheel axis in an engageable position and not restrict translation of the front wheel relative to the drive wheel axis in an inactive position, the limiter transitionable from the inactive position to the engageable position when the front wheel is in a first position relative to the drive wheel axis and prevented from transitioning from the inactive position to the engageable position when the front wheel is in a second position relative to the drive wheel axis.
