Abstract

A mattress for a hospital bed is provided. The mattress includes an encasing enclosing a compressible mattress portion and a rigid mattress portion. The compressible mattress portion has an integral construction extending from a head end of the bed to a foot end of the bed. The rigid mattress portion contracts from a first elongated position to a second retracted position, and the rigid portion contracting the compressible mattress portion therewith. The rigid mattress portion may be provided at any side or end section of the mattress. Accordingly, the width or length of the mattress can be modified.

16. The mattress of claim 1, wherein the mattress has an integral head section, seat section and foot section.

17. The mattress of claim 16, wherein a portion of the mattress is connected to a seat deck section of the bed.

18. The mattress of claim 16, further comprising a notch extending from a base of the compressible mattress portion between the head section and the seat section.

19. A variable size mattress for a bed, comprising:

an encasing enclosing a compressible mattress portion and a rigid mattress portion, the rigid mattress portion contracting from a first elongated position to a second retracted position, and the rigid portion contracting the compressible mattress portion therewith, wherein a portion of the compressible mattress portion is positioned above the rigid mattress portion, wherein the compressible mattress portion is connected to the rigid mattress portion a first end of the rigid mattress portion, and wherein there is an absence of a connection between the rigid mattress portion and the compressible mattress portion adjacent an opposing end of the rigid mattress portion.

20. A patient support for a bed, the patient support comprising:

a deck supported on a frame, the deck having a head end and a foot end, wherein the deck has a first deck section, a second deck section and a third deck section, the first deck section located adjacent the head end, the third deck section located adjacent the foot end, and the second deck section between the first deck section and the third deck section, wherein the first deck section is moveable from a generally horizontal position to a more vertical back-support position, and wherein the second deck section is pivotable upwards; and

,

a mattress supported on the deck, a portion of the mattress extending a distance beyond an edge of the foot deck a length, L₁, when the mattress is in a first position, such that the mattress is cantilevered and overhangs the foot end of the deck.

21. The patient support of claim 20, wherein the mattress has a first end adjacent the head end of the deck.

22. The patient support of claim 20, wherein the mattress retracts to a second position, in the second position a portion of the mattress extending a distance beyond the edge of the foot deck a length L₂, wherein L₂ is less than L₁.

23. The patient support of claim 20, wherein the mattress has a compressible mattress portion and a rigid mattress portion.

24. The patient support of claim 23, wherein the compressible mattress portion extends about a plurality of deck sections, and wherein the rigid mattress portion is positioned adjacent a foot deck section of the deck.
