See full text

A stair chair for use in transporting a patient in a seated position along stairs comprising a base, an upright coupled to the base, and a track assembly extending from the base for traversing stairs. A seat section is operatively attached to the upright and arranged for movement relative to the base between a plurality of vertical configurations including a first vertical configuration where the seat section is spaced from the base at a first distance for supporting the patient in the seated position, and a second vertical configuration where the seat section is spaced from the base at a second distance greater than the first distance. A lift mechanism is interposed between the base and the seat section to move the seat section between the plurality of vertical configurations. The lift mechanism moves the seat section to facilitate transitioning the patient to a standing position from the seated position.
