Abstract

A foldable sofa-bed includes: a base with an internal cavity and a rear member; a foldable bed that includes separate and distinct head, intermediate and seat sections, each with a respective cushion, wherein in a folded position, the intermediate and seat sections are generally horizontally disposed and positioned in vertically stacked relationship, with the intermediate and seat cushions facing generally upwardly, and the head section is generally vertically disposed and positioned adjacent the rear wall of the base, and in an unfolded position, the head, intermediate and seat sections are generally horizontally disposed in serial alignment; and a bed folding mechanism that is attached to the base and the head, intermediate and seat sections that controls the movement of the bed between the folded and unfolded positions. In moving from the folded to the unfolded position, the intermediate section maintains generally the same orientation.

Claims

1. A foldable sofa-bed, comprising:

a base with an internal cavity and a rear member, the base configured to rest on an underlying surface;

a foldable bed that includes separate and distinct head, intermediate and seat sections, each with a respective cushion, wherein in a folded position, the intermediate and seat sections are generally horizontally disposed and positioned in vertically stacked relationship, with the intermediate and seat cushions facing generally upwardly, and the head section is generally vertically disposed and positioned adjacent the rear member of the base, and in an unfolded position, the head, intermediate and seat sections are generally horizontally disposed and in serial alignment with each other; and

a bed folding mechanism that is attached to the base and the head, intermediate and seat sections that controls the movement of the bed between the folded and unfolded positions;

wherein the cushion of the head section faces generally forwardly in the folded position; and

further comprising a backrest cushion assembly attached to the base that moves a backrest cushion between lowered and raised positions.

2. The foldable sofa-bed defined in claim 1, wherein the seat section is supported by at least one wheel that rolls on the underlying surface.

3. The foldable sofa-bed defined in claim 2, wherein the bed folding mechanism includes a leg mounted to the seat section and to the wheel.

4. The foldable sofa-bed defined in claim 3, further comprises a front panel mounted to the leg, the front panel positioned below a front portion of the seat section.

5. The foldable sofa-bed defined in claim 1, wherein the intermediate section is supported by at least one wheel that rolls on the underlying surface.

6. The foldable sofa-bed defined in claim 1, wherein the bed folding mechanism further comprises a center leg mounted to the intermediate section and to the wheel, the center leg folding under the intermediate section in the folded position.

7. The foldable sofa-bed defined in claim 1, wherein the bed folding mechanism further includes a linear power actuator to move the bed between the folded and unfolded positions.

8. The foldable sofa-bed defined in claim 1, wherein the head, intermediate and seat sections are sized to form a king-sized bed.

9. A foldable sofa-bed, comprising:

a base with an internal cavity and a rear member, the base configured to rest on an underlying surface;

a foldable bed that includes separate and distinct head, intermediate and seat sections, each with a respective cushion, wherein in a folded position, the intermediate and seat sections are generally horizontally disposed and positioned in vertically stacked relationship, with the intermediate and seat cushions facing generally upwardly, and the head section is generally vertically disposed and positioned adjacent the rear member of the base, and in an unfolded position, the head, intermediate and seat sections are generally horizontally disposed and in serial alignment with each other;

a bed folding mechanism that is attached to the base and the head, intermediate and seat sections that controls the movement of the bed between the folded and unfolded positions; and

a linear power actuator to move the bed between the folded and unfolded positions, the linear actuator positioned beneath the intermediate section in the folded and unfolded positions.

10. The foldable sofa-bed defined in claim 9, further comprising a backrest cushion assembly attached to the base that moves a backrest cushion between lowered and raised positions.

11. The foldable sofa-bed defined in claim 9, wherein the seat section is supported by at least one wheel that rolls on the underlying surface;

and wherein the intermediate section is supported by at least one wheel that rolls on the underlying surface.

12. The foldable sofa-bed defined in claim 9, wherein the head, intermediate and seat sections are sized to form a king-sized bed.
