A hospital bed that is convertible to a chair for patient egress from the foot end of the bed. A patient support platform has serially hinged, normally horizontal head, seat, thigh and foot panels. To convert the horizontal bed to the chair configuration, the patient support platform in the lowermost vertical position is translated longitudinally toward the foot end of the bed. The head panel is pivoted upwardly and the foot panel pivots downwardly to a generally vertical attitude. The foot panel includes a collapsing portion which telescopes into a pivoting portion to thereby avoid interference with the floor as the foot panel is pivoted to a vertical attitude. When converted to the chair configuration, an area is vacated at the foot end of the bed to provide a space for docking a wheelchair or other ambulatory assisting device. The patient's feet rest directly on the floor in the chair configuration in that the foot panel collapses into itself as it pivots downwardly rather than pivoting along a second axis to underlie the patient's feet. Another embodiment includes a leg panel including a downwardly pivoting calf panel and a foot panel pivotally connected to a foot end of the calf panel. First and second links connect the calf and foot panels, respectively, to the frame. When the patient support moves longitudinally, the first link moves the calf panel to a generally vertical position and the second link moves the foot panel to a position aft of and against the calf panel. A foam mattress overlies the leg panel and is compressed by the action of the calf and foot panels. |
