A hospital bed includes a base, a lifting mechanism, a rotating frame configured to rotate horizontally relative to the base, and a patient support surface pivotally secured to the rotating frame. The patient support surface includes a back section, a seat section, and foot section that articulate relative to each other. The patient support surface translates from a bed configuration to a side-egress chair or stand assist configuration. The foot section includes a plurality of panels configured to move relative to each other in substantially parallel overlapping planes between an extended configuration and a retracted configuration when the patient support surface is in a chair or stand assist configuration. The foot section contacts a floor which causes the plurality of panels to move to the retracted configuration. Biasing members urge the plurality of panels to the extended configuration when the foot section no longer contacts the floor.

1. A hospital bed, comprising: a base comprising opposite end portions;a lifting mechanism secured to the base between the end portions; anda patient support surface pivotally secured to the lifting mechanism, wherein the patient support surface comprises a back section, a seat section, and a foot section configured to articulate relative to each other, and wherein the patient support surface is configured to translate from a bed configuration to a chair configuration;wherein the foot section comprises first, second, third, fourth, and fifth panels operably connected together that are configured to move relative to each other in substantially parallel overlapping planes between an extended configuration when the patient support surface is in a bed configuration and a retracted configuration when the patient support surface is in a chair configuration, wherein the first, third and fifth panels move relative to each other in a first plane, and wherein the second and fourth panels move relative to each other in a second plane. 2. The hospital bed of claim 1, wherein a free end of the foot section is configured to contact a floor surface when the patient support surface is in a chair configuration, and wherein contact with the floor surface forces the plurality of panels to move to the retracted configuration. 3. The hospital bed of claim 2, wherein the foot section comprises at least one biasing member configured to urge the plurality of panels to the extended configuration. 4. The hospital bed of claim 1, wherein the foot section further comprises a frame assembly, the frame assembly comprising: a foot section base having opposite first and second sides;a first section telescopically secured to the foot section base first side and movable relative to the foot section base between retracted and extended positions; anda second section telescopically secured to the foot section base second side and movable relative to the foot section base between retracted and extended positions. 5. The hospital bed of claim 4, wherein the foot section base comprises at least one biasing member configured to urge the first and second sections outwardly from the base to respective extended positions. 6. The hospital bed of claim 4, wherein the first and second sections each comprise a plurality of spaced-apart elongated legs telescopically secured to the base, wherein the base comprises a respective plurality of biasing members associated with the first section legs that are configured to urge the first section outwardly from the base to a respective extended position, and wherein the base comprises a respective plurality of biasing members associated with the second section legs that are configured to urge the second section outwardly from the base to a respective extended position. 7. The hospital bed of claim 4, wherein the first panel is secured to the first section, the third panel is secured to the base, and the fifth panel is secured to the second section. 8. The hospital bed of claim 7, wherein the second panel is slidably secured to the first and third panels, and the fourth panel is slidably secured to the third and fifth panels. 9. The hospital bed of claim 4, wherein the second section of the frame assembly is pivotally secured to the seat section. 10. The hospital bed of claim 4, further comprising an actuator configured to move the foot section between a substantially co-planar configuration relative to the seat section and a substantially orthogonal configuration relative to the seat section. 11. The hospital bed of claim 10, wherein the frame assembly first section is configured to contact a floor surface when the foot section is moved to the substantially orthogonal configuration relative to the seat section, and wherein contact with the floor surface causes the frame assembly first and second sections to move to respective retracted positions. 12. The hospital bed of claim 11, wherein the frame assembly first section comprises at least one roller or wheel configured to contact the floor surface and roll along the floor surface as the foot section is moved to the substantially orthogonal configuration relative to the seat section. 13. The hospital bed of claim 1, wherein the lifting mechanism is configured to raise and lower the patient support surface relative to the base, and further comprising a rotating frame mounted on the lifting mechanism, wherein the rotating frame is configured to rotate horizontally relative to the base, wherein the patient support surface is pivotally secured to the rotating frame, and wherein the patient support surface is configured to translate from a bed configuration to a side-egress chair configuration. 14. A method of translating a hospital bed to an egress configuration, wherein the bed comprises a base having opposite end portions, a lifting mechanism secured to the base between the end portions, and a patient support surface pivotally secured to the lifting mechanism, the method comprising: articulating back, seat and foot sections of the patient support surface relative to each other from a substantially co-planar configuration to a chair configuration, wherein the foot section includes a plurality of panels that are configured to move relative to each other in substantially parallel overlapping planes between an extended configuration when the patient support surface is in a bed configuration and a retracted configuration when the patient support surface is in a chair configuration, wherein the foot section comprises first, second, third, fourth, and fifth panels operably connected together; andcontacting a floor surface with the foot section such that the first, third and fifth panels move relative to each other in a first plane, and such that the second and fourth panels move relative to each other in a second plane parallel to and over or under the first plane; andforcing the plurality of panels to move to the retracted configuration in response to the floor contact. 15. The method of claim 14, further comprising rotating the back, seat and foot sections 90 degrees to a side egress position prior to the contacting step.
