Abstract
A patient support apparatus includes a litter that includes a support structure articulable between seated and supine configurations. The support structure includes a seat section and a leg section coupled to the seat section and articulable relative to the seat section around a seat axis between first and second angular positions corresponding to the seated and supine configurations, respectively. The apparatus includes a steerable wheel assembly coupled to and rotatable relative to the leg section around a steering axis, and a wheel system including a deployment frame coupled to and rotatable relative to the leg section around a pivot axis and a wheel coupled to and rotatable relative to the deployment frame around a wheel axis parallel to the seat axis. The apparatus includes a wheel deployment mechanism configured to rotate the deployment frame around the pivot axis when the leg section articulates between the first and second angular positions.
