Abstract

A bed that converts into a chair is provided. The bed includes a base frame assembly, an intermediate frame assembly and a patient support deck. The patient support deck includes a head deck section, an intermediate deck section and a foot deck section.

Claims (36)

1. A hospital bed, comprising:

a base frame assembly;

an intermediate frame assembly coupled to the base frame assembly;

a patient support assembly coupled to the intermediate frame assembly, and

a weigh frame assembly is positioned between the intermediate frame assembly and the patient support assembly,

wherein the intermediate frame assembly is raised to a raised position and lowered to a lowered position via a plurality of arm assemblies and a plurality of actuators connected to the base frame assembly to allow the intermediate frame assembly to nest within the base frame assembly in the lowered position,

wherein in a lowered-most position, portions of the intermediate frame assembly are lower than portions of the base frame assembly.

2. The hospital bed of claim 1 , wherein the plurality of actuators include a first actuator to raise and lower a head end of the intermediate frame assembly, and a second actuator to raise and lower a foot end of the intermediate frame assembly.

3. The hospital bed of claim 2 , wherein the plurality of arm assemblies include a first arm assembly and a second arm assembly, the first arm assembly connected to a head end of the intermediate frame assembly and the first actuator, the second arm assembly connected to a foot end of the intermediate frame assembly and the second actuator.

4. The hospital bed of claim 3 , wherein the first arm assembly and the second arm assembly reside generally inline with the intermediate frame assembly.

5. The hospital bed of claim 1 , further including a patient support deck coupled to the patient support assembly, the patient support deck having a head deck section, a seat deck section, and a foot deck section, the head deck section located adjacent a head end of the hospital bed, the foot deck section located adjacent a foot end of the hospital bed, the seat deck section being between the head deck section and the foot deck section, the patient support deck is convertible to an expanding width bed configuration, wherein the patient support deck converts to a wider patient support surface at various sections of the hospital bed.

6. The hospital bed of claim 5 , wherein the head deck section includes a first side head deck extender assembly and a second side head deck extender assembly, the first side head deck extender assembly utilized to increase a width of the hospital bed at a first side of the hospital bed, and the second side head deck extender assembly utilized to increase the width of the hospital bed at a second side of the hospital bed.

7. The hospital bed of claim 6 , wherein the first and second side head deck extender assemblies are independently moveable from a first retracted position to a second expanded position.

8. The hospital bed of claim 5 , wherein the seat deck section includes a first side seat deck extender assembly and a second side seat deck extender assembly, the first side seat deck extender assembly utilized to increase a width of the hospital bed at a first side of the hospital bed, and the second side seat deck extender assembly utilized to increase the width of the hospital bed at a second side of the hospital bed.

9. The hospital bed of claim 8 , wherein the first and second side seat deck extender assemblies are independently moveable from a first retracted position to a second expanded position.

10. The hospital bed of claim 1 , wherein the weigh frame assembly is coupled to the intermediate frame assembly by a plurality of load cells or load beams and the patient support assembly is coupled to the weigh frame assembly by a plurality of actuators that raise and lower a head section, an intermediate section, and a foot section of the hospital bed at various angular orientations.

11. The hospital bed of claim 1 , further including a first side rail and a second side rail.

12. A hospital bed, comprising:

a base frame assembly,

an intermediate frame assembly coupled to the base frame assembly,

a weigh frame assembly coupled to the intermediate frame assembly by a plurality of load beams,

a patient support assembly coupled to the weigh frame assembly,

wherein the weigh frame assembly is positioned between the intermediate frame assembly and the patient support assembly,

wherein the intermediate frame assembly is raised to a raised position and lowered to a lowered position via a plurality of arm assemblies and a plurality of actuators connected to the base frame assembly to allow the intermediate frame assembly to nest within the base frame assembly in the lowered position, and

a patient support deck coupled to the patient support assembly, the patient support deck having a head deck section, a seat deck section, and a foot deck section, the head deck section located adjacent a head end of the hospital bed, the foot deck section located adjacent a foot end of the hospital bed, the seat deck section being between the head deck section and the foot deck section,

the head deck section, the seat deck section, and the foot deck section can be positioned in a chair configuration wherein the foot deck section is substantially vertical.

13. The hospital bed of claim 12 , wherein the plurality of actuators include a first actuator to raise and lower a head end of the intermediate frame assembly, and a second actuator to raise and lower a foot end of the intermediate frame assembly.

14. The hospital bed of claim 13 , wherein the plurality of arm assemblies include a first arm assembly and a second arm assembly, the first arm assembly connected to a head end of the intermediate frame assembly and the first actuator, the second arm assembly connected to a foot end of the intermediate frame assembly and the second actuator.

15. The hospital bed of claim 14 , wherein the first arm assembly and the second arm assembly reside generally inline with the intermediate frame assembly.

16. The hospital bed of claim 12 , wherein the patient support deck is convertible to an expanding width bed configuration, wherein the patient support deck converts to a wider patient support surface at one or more sections of the hospital bed.

17. The hospital bed of claim 12 , wherein the head deck section includes a first side head deck extender assembly and a second side head deck extender assembly, the first side head deck extender assembly utilized to increase a width of the hospital bed at a first side of the hospital bed, and the second side head deck extender assembly utilized to increase the width of the hospital bed at a second side of the hospital bed.

18. The hospital bed of claim 17 , wherein the first and second side head deck extender assemblies are independently moveable from a first retracted position to a second expanded position.

19. The hospital bed of claim 12 , wherein the seat deck section includes a first side seat deck extender assembly and a second side seat deck extender assembly, the first side seat deck extender assembly utilized to increase a width of the hospital bed at a first side of the hospital bed, and the second side seat deck extender assembly utilized to increase the width of the hospital bed at a second side of the hospital bed.

20. The hospital bed of claim 19 , wherein the first and second side seat deck extender assemblies are independently moveable from a first retracted position to a second expanded position.

21. The hospital bed of claim 12 , wherein the weigh frame assembly is coupled to the intermediate frame assembly by a plurality of load cells or load beams and the patient support assembly is coupled to the weigh frame assembly by a plurality of actuators that raise and lower a head section, an intermediate section, and a foot section of the hospital bed at various angular orientations.

22. The hospital bed of claim 12 , further including a first side rail and a second side rail.
