A mattress may include one or more sections movable relative to one another, such as an adjustable head portion or an adjustable foot portion. Motors and/or other drive systems may be integrated within the mattress, and the mattress may be adapted for use with a convention frame or a conventional foundation.
Claims29
An adjustable mattress comprising:
- a first section and a second section overlying a common rigid planar platform, with respective upper surfaces of the first section and the second section moveable relative to each other and together forming at least a portion of a sleeping surface of the adjustable mattress;
- a first mechanical drive unit within the adjustable mattress, the first mechanical drive unit connected between the platform and at least one of the first section and the second section and providing a mechanical force to move the upper surface of the first section relative to the upper surface of the second section;
- and
- a flexible sheet comprising a first sheet member coextensive with the first section and a second sheet member coextensive with the second section and disposed between the first mechanical drive unit and bottom surfaces of the first and second sections, said flexible sheet being continuous in a longitudinal direction of the mattress at least across one of the first and second sections,
- wherein the first sheet member is attached to the second sheet member by an articulated hinge and a force of the first mechanical drive unit is distributed across a region of the first section by the first sheet member associated with that section.

An adjustable mattress comprising:
- a first section and a second section overlying a common rigid planar platform, with respective upper surfaces of the first section and the second section moveable relative to each other and together forming a sleeping surface of the adjustable mattress;
- a mechanical means within the adjustable mattress for moving the upper surface of the first section relative to the upper surface of the second section;
- and
- a flexible mid-sheet comprising a first sheet member coextensive with the first section and a second sheet member coextensive with the second section and disposed between the mechanical means and the first and second sections, said flexible mid-sheet being continuous in a longitudinal direction of the mattress at least across one of the first and second sections,
- wherein the first sheet member is attached to the second sheet member by an articulated hinge and a force of the mechanical means is distributed across a region of the first section by the first sheet member coextensive with that section.
2 more elements
An articulated mattress having a flexible cover, comprising:
- a base element forming a planar region parallel to a sleeping surface of said mattress;
- a sleeping element comprising:
- a first section and a second section with respective upper surfaces of the first section and the second section moveable relative to each other and together forming the sleeping surface of the mattress;
- one or more mattress cores disposed on and above a flexible sheet, said flexible sheet comprises a first sheet member coextensive with the first section and a second sheet member coextensive with the second section, the first sheet member is attached to the second sheet member by an articulated hinge, and the flexible sheet is continuous in a longitudinal direction of the mattress at least across one of the first and second sections;
- and
- articulation means fixedly attached to said base element, comprising a screw drive means fixedly mounted to said base element;
- and
- linkage means coupled to said screw drive, whereby actuation of said screw drive causes said linkage to bear on said flexible sheet, thereby displacing said sheet;
- wherein the screw drive is distributed across a region of the corresponding one of the first and second sections by the first or second sheet member associated with that section, and
- wherein said base element, said sleeping element, said articulation means, and said flexible sheet are located within said flexible cover.
