1. A patient support apparatus for supporting a patient, the patient support apparatus comprising:
a litter comprising a support structure articulable between a seated configuration and a supine configuration, and configured to support the patient in each of the seated and supine configurations, with the support structure comprising:
a seat section;
a leg section coupled to the seat section and articulable relative to the seat section between a first angular position in the seated configuration and a second angular position, different from the first angular position, in the supine configuration;
a foot section coupled to the leg section and arranged for translation relative to the leg section along a linear path between a first position associated with the seated configuration and a second position, different from the first position, associated with the supine configuration;
a rail mounted to at least one of the leg and foot sections and longitudinally aligned with the translation of the foot section between the first and second positions and a roller bearing rotatably mounted to the other one of the leg and foot sections and in engagement with the rail, the roller bearing configured to roll along the rail and facilitate the translation of the foot section; and
a litter actuation mechanism coupled to the litter and configured to move the support structure between the seated and supine configurations, with the litter actuation mechanism simultaneously articulating the leg section relative to the seat section and translating the foot section relative to the leg section along the linear path.
