摘要： The present disclosure includes methods of operating 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, one or more pairs of arm assemblies, and one or more sensors. The arm assembly includes a wheel configured to move from a first spatial location when the wheelchair is operating on flat, level ground to a second spatial location that is different than the first spatial location. Arm limiters can selectively engage the arm assembly based on at least one of a seat position, position of the arm assembly, and surface conditions of ground surface. The arm limiters can limit the range of motion of the arm assembly and sometimes other operational aspects of the chair. The methods adjust the maximum operational speed of the wheelchair when the seat is in an elevated position based on sensor data relating to one or more of the arm limiter position and the position of the frame.

摘要： A powered wheelchair comprises a frame and an arm assembly that includes an arm that is pivotably coupled to the frame. The arm assembly includes a wheel coupled to the arm. A drive system is coupled to the arm assembly and configured to drive a drive wheel. An arm limiter is pivotably coupled to the suspension and coupled to one or more of the arm assembly and the drive system in an engaged position. The arm limiter is configured to limit movement of the arm assembly in the engaged position.

摘要： A seat positioning system includes a base frame having a pair of forward slots and a pair of rear slots, and a seat frame having a front end and a back end. The seat frame is coupled to the base frame and movable relative to the base frame. A first pair of linkages is slideably coupled to the pair of forward slots and connects the frames. A first pair of locking devices has a locked configuration adapted to prevent the first pair of linkages from sliding relative to the pair of forward slots and an unlocked configuration adapted to allow the first pair of linkages to slide relative to the pair of forward slots. A second pair of linkages slideably is coupled to the pair of rear slots and connects the frames. An actuator is pivotally connected to both the seat frame and the base frame and is configured to extend and contract to move the seat frame relative to the base frame.
