Abstract

A lift-recliner chair includes a base portion and a seat portion pivotally connected to the base portion about a first pivot axis. The chair also includes a back portion pivotally connected to the seat portion about a second pivot axis and an actuator assembly for moving the seat portion with respect to the base and back portions with respect to the seat portion to alter the chair configuration. The base portion includes a pair of substantially vertical side panels and a rear panel extending between the side panels. The seat portion includes a seat frame having a pair of substantially vertical side panels arranged substantially parallel with and adjacent to the respective side panels of the base portion and a curved rear panel extending between the side panels of the base portion. The center of curvature of the curved rear panel is substantially coincident with the first pivot axis.

Claims (21)

1. A lift-recliner chair comprising:

a base portion;

a seat portion pivotally connected to the base portion about a first pivot axis;

a back portion pivotally connected to the seat portion; and

an actuator assembly for moving the seat portion with respect to the base portion and the back portion with respect to the seat portion to alter the configuration of the chair, wherein the base portion includes a pair of substantially vertical side panels and a rear panel extending between the side panels, wherein the seat portion includes a seat frame having a pair of substantially vertical side panels arranged substantially parallel with and adjacent to the respective side panels of the base portion, the seat frame further including a curved rear panel extending between the pair of vertical side panels of the seat frame, and wherein the center of curvature of the curved rear panel is substantially coincident with the first pivot axis.

2. A lift-recliner chair as claimed in claim 1 wherein the seat portion is movable between a substantially horizontal position in which at least part of the seat portion is nested with the base portion and an inclined position in which the seat portion is extended from the base portion.

3. A lift-recliner chair as claimed in claim 1 wherein the seat portion is nested within and extendable from the base portion.

4. A lift-recliner chair as claimed in claim 1 wherein the first pivot axis is positioned towards a front of the base portion.

5. A lift-recliner chair as claimed in claim 1 wherein the seat portion is pivotally connected to the side panels of the base portion and the seat portion is at least partially supported by the side panels of the base portion.

6. A lift-recliner chair as claimed in claim 1 wherein the back portion comprises a generally rectangular frame and a pair of pivot arms which extend from the frame and pivotally connect the frame to the seat portion.

7. A lift-recliner chair as claimed in claim 6 wherein the pivot arms pivotally connect the back portion to the side panels of the seat portion.

8. A lift-recliner chair as claimed in claim 6 wherein the pivot arms comprise part of a bell-crank for moving the back portion about a pivot axis spaced from the rectangular frame.

9. A lift-recliner chair as claimed in claim 6 wherein the pivot arms extend parallel with and adjacent to respective vertical side panels of the seat portion on an interior side thereof.

10. A lift-recliner chair as claimed in claim 1 wherein the actuator assembly is operatively coupled to the back portion and moves the back portion relative to the seat portion such that the back portion pivots away from the seat portion when the seat portion is raised.

11. A lift-recliner chair as claimed in claim 10 wherein the back portion is arranged to pivot away from the seat portion once the seat portion is moved during lifting to a pre-determined position between a lowered position and a fully raised position.

12. A lift-recliner chair as claimed in claim 1 wherein the actuator assembly comprises a first actuator for moving the seat portion and a second actuator for moving the back portion.

13. A lift-recliner chair as claimed in claim 12 wherein the first and second actuators are operably coupled to the base portion.

14. A lift-recliner chair as claimed in claim 1 wherein the base portion further comprises a front panel, which is pivotally mounted to the side panels of the base portion and movable with respect to the side and rear panels of the base portion for movement from a generally vertical position to a generally horizontal position to provide a retractable footrest.

15. A lift-recliner chair as claimed in claim 14 wherein the actuator assembly comprises a third actuator operably coupled to the side panels of the base portion for moving the front panel about a pivot axis.

16. A lift-recliner chair as claimed in claim 14 wherein the front panel is pivotally movable with respect to the base portion about a pivot axis corresponding substantially to a position of a seated user's knee joint.

17. A lift-recliner chair as claimed in claim 14 wherein a pivot axis of the front panel is coincident with the first pivot axis.
