Abstract

A seating device such as a chair or sofa. The seating device includes a frame, a seat platform supported by the frame, and a backrest attached to the seat platform. The seat platform has opposite front and rear ends. The backrest has a first backrest portion extending upwardly from proximate the rear end of the seat platform. A lower end of the first backrest portion is positioned adjacent to an upper surface of the seat platform. The first backrest portion is capable of being moved forwardly and rearwardly along the upper surface of the seat platform while the lower end remains proximate the upper surface of the seat platform. A backrest-adjustment powered actuator operates the backrest for moving at least the first backrest portion forwardly and rearwardly partially along the upper surface of the seat platform to adjust an effective depth of the seat platform.

Claims

1. A seating device comprising:

a frame;

a seat platform supported by the frame, the seat platform including opposite front and rear ends and configured to support a seat cushion;

a backrest having;

a first backrest portion extending upwardly from proximate the rear end of the seat platform, the first backrest portion comprising an upper backrest frame adjustably mounted to a lower backrest frame, the lower backrest frame configured to slidably vertically adjust relative to the upper backrest frame such that a lower end of the first backrest portion may be positioned proximate an upper surface of the seat platform or seat cushion, and

a second backrest portion rearward of the first backrest portion and to which the first backrest portion is movably mounted,

wherein the backrest is mounted to the seat platform and the first backrest portion is capable of being moved forwardly and rearwardly along the upper surface of the seat platform while the lower end remains proximate the upper surface of the seat platform or the seat cushion;

a first backrest-adjustment powered actuator operatively associated with the backrest for moving at least the first backrest portion forwardly and rearwardly relative to the second backrest portion and partially along the upper surface of the seat platform to adjust an effective depth of the seat platform; and

a recline-adjustment powered actuator, the recline-adjustment powered actuator operably connected to the second backrest portion to adjust the angle of the second backrest portion relative to the seat platform.

2. The seating device according to claim 1, wherein the seat platform is adjustably mounted to the frame, and the seating device includes a pair of seat-adjustment powered actuators, wherein the pair of seat-adjustment actuators are configured to adjust an inclination of the seat platform relative to the frame, and are configured to move the seat platform, as a whole, upwardly and downwardly relative to the frame.

3. The seating device according to claim 2, wherein raising the rear end of the seat platform with the respective seat-adjustment actuator pushes the lower end of the first backrest portion upwardly.

4. The seating device according to claim 1, further comprising:

an extendable footrest; and

a footrest-adjustment powered actuator for extending and retracting the footrest relative to the frame.

5. An upholstered seating device comprising:

an upholstered frame;

an upholstered seat platform supported by the frame, the seat platform including opposite front and rear ends;

an upholstered backrest having;

a first backrest portion extending upwardly from proximate the rear end of the seat platform, the first backrest portion comprising an upper backrest frame adjustably mounted to a lower backrest frame, the lower backrest frame configured to freely vertically adjust relative to the upper backrest frame such that a lower end of the first backrest portion may be positioned proximate an upper surface of the seat platform, and

a second backrest portion rearward of the first backrest portion and to which the first backrest portion is movably mounted,

wherein the backrest is mounted to the seat platform and the first backrest portion is capable of being moved forwardly and rearwardly relative to the second backrest portion and along the upper surface of the seat platform while the lower end remains proximate the upper surface of the seat platform;

a first backrest-adjustment actuator operatively associated with the backrest configured for moving at least the first backrest portion forwardly and rearwardly partially along the upper surface of the seat platform to adjust an effective depth of the seat platform while a user is sitting in the seating device; and

a recline-adjustment powered actuator, the recline-adjustment powered actuator operably connected to the second backrest portion to adjust the angle of the second backrest portion relative to the seat platform.

6. The upholstered seating device according to claim 5, wherein the seat platform is adjustably mounted to the frame, and the seating device includes a pair of seat-adjustment powered actuators, one actuator of the pair is positioned adjacent to the front end and the other actuator of the pair is positioned adjacent to the rear end, wherein the pair of seat-adjustment actuators can work independently to adjust an inclination of the seat platform relative to the frame, and can work together to move the seat platform, as a whole, upwardly and downwardly relative to the frame.

7. The upholstered seating device according to claim 6, wherein raising the rear end of the seat platform with the respective seat-adjustment actuator pushes the lower end of the first backrest portion upwardly.

8. The upholstered seating device according to claim 5, further comprising:

an extendable footrest; and

a footrest-adjustment powered actuator for extending and retracting the footrest relative to the frame.

9. Furniture comprising:

a frame;

a seat platform supported by the frame, the seat platform including opposite front and rear ends and an upper surface;

a backrest extending upwardly from proximate the rear end of the seat platform, the backrest including;

a first portion providing a forwardmost surface, the forwardmost surface configured for supporting at least a lower back of a user seated in the furniture, the forwardmost surface having a lower edge proximate the upper surface of the seat platform; and

a second portion operably supporting the first portion; and

a first powered actuator capable of adjusting an inclination of the forwardmost surface of the backrest relative to the upper surface of the seat platform,

wherein the first portion of the backrest adjusts relative to the second portion to maintain an effective depth of the seat platform, and

a second powered actuator capable of adjusting an inclination of the second portion of the backrest relative to the seat platform,

wherein the first portion of the backrest comprises an upper frame movably mounted to a lower frame, the lower frame being adjustable relative to the upper frame such that a height of the lower frame of the first portion adjusts relative to the upper frame, as the inclination of the second portion changes.

10. The furniture according to claim 9, further comprising:

an adjustable footrest; and

a footrest-adjustment powered actuator configured to extend and retract the footrest.

11. The furniture according to claim 10, wherein the seat platform is adjustably mounted to the frame, and the furniture includes a pair of seat-adjustment powered actuators, wherein the pair of seat-adjustment actuators are configured to adjust an inclination of the seat platform relative to the frame, and are configured to move the seat platform, as a whole, upwardly and downwardly relative to the frame.

12. A backrest attachable to a seating platform of a seating device, the backrest comprising:

a rearward backrest frame configured to be reclinably attached to the seating device; and

a forward backrest frame pivotably attached to an upper end of the rearward backrest frame, the forward backrest frame comprising;

an upper backrest frame pivotably attached to the upper end of the rearward backrest frame, and

a lower backrest frame slidably attached to the upper backrest frame such that the lower backrest frame is adjustable relative to the upper backrest frame to adjust a length of the forward backrest frame,

wherein adjusting the length of the forward backrest frame is configured to allow a bottom of the lower backrest frame to remain in contact with the seating platform when the rearward backrest frame is reclined.

13. The backrest according to claim 12, wherein:

the lower backrest frame slides, substantially freely, relative to the upper backrest frame.

14. The backrest according to claim 13, wherein at least two slide joints slidably support the lower backrest frame at least partially within the upper backrest frame.
