摘要： A patient transport apparatus for transporting a patient. A seat section is pivotably coupled to a support structure about a seat axis. A front wheel is operatively attached to a front strut of the support structure, and a carrier is arranged for movement relative to the support. The carrier includes a shaft defining a wheel axis, a rear wheel supported for rotation about the wheel axis, a track having a belt, and a hub supporting the shaft and the track for concurrent pivoting movement about a hub axis defined by a upright of the support structure. The hub axis extends through a plane intersecting the seat axis, fixed relative to the upright, and defining opposing first and second sides. Movement of the carrier from a chair configuration to a stair configuration simultaneously deploys the track and moves the wheel axis from the first side to the second side.
