Abstract

A mattress assembly includes a mattress and an outer mattress shell that covers the mattress and has a patient support portion and a sleep deck portion. The outer mattress shell defines an interior surface and an exterior surface. A bonding strip is coupled to the interior surface of the outer mattress shell and a fastening strip is coupled to the exterior surface of the outer mattress shell. A weld extends through the exterior surface and through the interior surface of the outer mattress shell. A clasp locker is operably coupled to the fastening strip and detachably couples the patient support portion to the sleep deck portion of the outer mattress shell.

First claim

What is claimed is:

1. A mattress assembly, comprising:
a mattress;
an outer mattress shell covering the mattress and having a patient support portion and a sleep deck portion, the outer mattress shell defining an interior surface and an exterior surface;
a bonding strip coupled to the interior surface of the outer mattress shell;
a fastening strip coupled to the exterior surface of the outer mattress shell;
a weld extending through the exterior surface and through the interior surface of the outer mattress shell; and
a clasp locker operably coupled to the fastening strip and detachably coupling the patient support portion to the sleep deck portion of the outer mattress shell.

2. The mattress assembly of claim 1 , further comprising:
a flap coupled to the outer mattress shell via the weld, wherein the bonding strip is disposed between the flap and the exterior surface of the outer mattress shell.

3. The mattress assembly of claim 2 , further comprising:
a fastening member that secures the flap to the outer mattress shell.

4. The mattress assembly of claim 2 , wherein one end of the flap is operably coupled to the weld.

5. The mattress assembly of claim 1 , wherein the outer mattress shell includes a fold, and wherein the bonding strip is positioned within the fold, and wherein the bonding strip and the fold are coupled to the outer mattress shell via the weld.

6. The mattress assembly of claim 1 , wherein the bonding strip includes a first bonding strip disposed on a first side of a corner portion of the outer mattress shell and a second bonding strip disposed on a second side of the corner portion of the outer mattress shell.

7. The mattress assembly of claim 1 , further comprising:
a radio frequency weld coupling the clasp locker to the exterior surface of the outer mattress shell.

8. The mattress assembly of claim 1 , wherein the bonding strip is defined by first and second bonding strips that are disposed on a first section and a second section of the interior surface.

9. The mattress assembly of claim 8 , wherein the first boding strip and the second bonding strip overlap and are at least partially coupled together.

10. The mattress assembly of claim 1 , wherein the weld extends between the patient support portion and the sleep deck portion.

11. A mattress assembly comprising:
a mattress;
an outer mattress shell encasing the mattress, the outer mattress shell including a fold defined by a weld extending through the outer mattress shell; and
a mattress retention assembly including a retention feature that has a planar portion extending below the outer mattress shell and a clasping portion, wherein the retention feature includes a raised portion, and wherein the raised portion is integrally formed with the planar portion.

12. The mattress assembly of claim 11 , wherein the clasping portion defines a recessed portion of the retention feature.

13. The mattress assembly of claim 11 , wherein the clasping portion and the planar portion couple the retention feature to a sleep deck of a hospital bed via a compressive force.

14. The mattress assembly of claim 13 , further comprising:
a clasp locker operably coupled to a fastening strip and detachably coupling a patient support portion to the sleep deck portion of the outer mattress shell.

15. The mattress assembly of claim 11 , wherein a bonding strip is defined by first and second bonding strips that are disposed on a first section and a second section of an interior surface.

16. The mattress assembly of claim 15 , wherein the first boding strip and the second bonding strip overlap and are at least partially coupled together.

17. A method for manufacturing a mattress comprising:
forming said mattress having an outer mattress shell that includes a patient support portion and a sleep deck portion, the outer mattress shell defining an interior surface and an exterior surface;
applying at least one bonding strip to the interior surface of the outer mattress shell;
coupling a clasp locker to detachably couple the patient support portion of the outer mattress shell to the sleep deck portion proximate the at least one bonding strip;
applying electromagnetic energy to the outer mattress shell and the at least one bonding strip at an attachment site to operably couple the outer mattress shell with the at least one bonding strip; and
applying pressure to the outer mattress shell and the at least one bonding strip at the attachment site.

18. The method of claim 17 , wherein applying at least one bonding strip further comprises the step of:
positioning a first bonding strip and a second bonding strip on the outer mattress shell, wherein the first bonding strip and the second bonding strip are separated by an adjoining section of the outer mattress shell.

19. The method of claim 18 , further comprising the steps of:
removing a portion of the outer mattress shell to define a corner portion;
positioning the first bonding strip and the second bonding strip proximate the corner portion of the outer mattress shell;
folding the corner portion of the outer mattress shell proximate the first bonding strip and the second bonding strip such that the first bonding strip and the second bonding strip at least partially overlap; and
radiofrequency welding the corner portion, the first bonding strip, and the second bonding strip.

20. The method of claim 17 , further comprising the steps of:
folding the outer mattress shell around the at least one bonding strip to define a fold of the outer mattress shell;
positioning a fastening strip proximate the fold; and
welding with radiofrequency the fold, the at least one bonding strip, and the fastening strip.
