摘要： A vehicle may include a flutter resistant caster. The vehicle may include a frame, a drive wheel coupled to the frame, a caster housing coupled to the frame, a caster, a locking element, a first bearing, and a biasing element. The caster housing may include an opening. The caster may include a caster wheel and a caster stem extending through the opening in the caster housing. The caster stem may be configured to rotate relative to the caster housing. The locking element may be coupled to the caster stem. The first bearing may be coupled to the caster stem. The biasing element may be coupled to the caster stem. The biasing element may be configured to exert a force on the first bearing.

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.

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.
