Abstract

A furniture member may include a base assembly, a frame assembly and a tilt mechanism. The base assembly includes rails having a track and a stop plug received in the track. The frame assembly includes a base frame, a seatback frame and a seat bottom frame. The seatback frame is rotatably coupled to the base frame. The seat bottom frame is coupled to the seatback frame such that rotation of the seatback frame causes movement of the seat bottom frame relative to the seatback frame and the base frame. The tilt mechanism is coupled to the seat bottom frame and engages the tracks such that rotation of the seatback frame relative to the base frame causes bearings of the tilt mechanism to slide along the tracks, thereby translating the base frame relative to the base assembly. The bearings contact stop plugs when the seatback is in a fully reclined position.

First claim

What is claimed is:

1. A furniture member comprising:
a base assembly including a pair of rails extending parallel to each other between front and rear portions of the base assembly, each of the rails including a track and a stop plug at least partially received in a front end of the track;
a frame assembly including a base frame, a seatback frame and a seat bottom frame, the seatback frame being rotatably coupled to the base frame, the seat bottom frame being movably coupled to the seatback frame such that rotation of the seatback frame causes corresponding movement of the seat bottom frame relative to the seatback frame and the base frame; and
a tilt mechanism supporting the base frame and coupled to the seat bottom frame, the tilt mechanism including drive links and side plates that slidably engage the tracks such that rotation of the seatback frame relative to the base frame causes the drive links and side plates to slide along the tracks, thereby translating the base frame relative to the base assembly, each of the side plates including a bearing that contacts one of the stop plugs when the seatback frame is in a fully reclined position,
wherein a pair of base stop members are fixedly attached to the base frame, the base stop members are spaced apart from the stop plugs when the seatback frame is in the fully reclined position and abut the stop plugs when the seatback frame is in an upright position.

2. The furniture member of claim 1 , wherein a side stop member is fixed relative to each of the base stop members, and wherein interference between side stop members and the tracks restricts relative lateral movement between the base frame and the base assembly.

3. The furniture member of claim 2 , wherein each base stop member includes first and second legs forming an L-shaped profile, and wherein both of the first and second legs contacts the corresponding stop plug.

4. The furniture member of claim 1 , wherein the base frame tilts relative to the base assembly as the base frame translates relative to the base assembly.

5. The furniture member of claim 1 , further comprising a legrest mechanism that is movable between extended and retracted positions independently of movement of the seatback frame relative to the base frame.

6. The furniture member of claim 5 , further comprising a first linear actuator and a second linear actuator, the first linear actuator powering movement of the tilt mechanism, the second linear actuator powering movement of the legrest mechanism.

7. The furniture member of claim 6 , wherein the first linear actuator powers rotation of the seatback frame relative to the base frame.

8. The furniture member of claim 7 , wherein the first linear actuator powers movement of the seat bottom frame relative to the base frame.

9. The furniture member of claim 8 , wherein the first and second linear actuators are aligned with each other and with an axis that extends vertically upward from a support surface upon which the furniture member is situated for normal use, the axis being perpendicular to the support surface.

10. The furniture member of claim 9 , wherein each base stop member includes first and second legs forming an L-shaped profile, and wherein both of the first and second legs contacts the corresponding stop plug, and wherein a side stop member is fixed relative to each of the base stop members, and wherein interference between the side stop members and the tracks restricts relative lateral movement between the base frame and the base assembly.

11. The furniture member of claim 8 , wherein actuation of only the second linear actuator while the seatback frame is in the upright position to move the legrest mechanism from the retracted position to the extended position causes the seatback frame and the base frame to tilt rearward relative to the base assembly from the upright position to a pre-tilt position.

12. The furniture member of claim 11 , further comprising a first switch controlling operation of the first actuator independently from the second actuator, a second switch controlling operation of the second actuator independently of the first actuator, and a third switch controlling simultaneous actuation of the first and second actuators.

13. A furniture member comprising:
a base assembly including a pair of rails extending parallel to each other between front and rear portions of the base assembly;
a frame assembly including a base frame, a seatback frame and a seat bottom frame, the seatback frame being rotatably coupled to the base frame, the seat bottom frame being movably coupled to the seatback frame such that rotation of the seatback frame causes corresponding movement of the seat bottom frame relative to the seatback frame and the base frame;
a tilt mechanism supporting the base frame and coupled to the seat bottom frame, the tilt mechanism including bearings that movably engage the rails such that rotation of the seatback frame relative to the base frame causes the bearings to move along the rails, thereby translating the base frame relative to the base assembly; and
a pair of base stop members are fixedly attached to the base frame, the base stop members are spaced apart from the rails when the seatback frame is in a fully reclined position and abut the rails when the seatback frame is in an upright position, each of the base stop members including a side stop member fixed relative thereto,
wherein interference between the side stop members and the rails restricts relative lateral movement between the base frame and the base assembly.

14. The furniture member of claim 13 , wherein each of the rails includes a track and a stop plug at least partially received in a front end of the track.

15. The furniture member of claim 14 , wherein the bearings contact the stop plugs when the seatback frame is in the fully reclined position.

16. The furniture member of claim 13 , wherein each base stop member includes first and second legs forming an L-shaped profile, and wherein both of the first and second legs contacts the corresponding rail.

17. The furniture member of claim 13 , wherein the base frame tilts relative to the base assembly as the base frame translates relative to the base assembly.

18. The furniture member of claim 13 , further comprising a legrest mechanism that is movable between extended and retracted positions independently of movement of the seatback frame relative to the base frame.

19. The furniture member of claim 18 , further comprising a first linear actuator and a second linear actuator, the first linear actuator powering movement of the tilt mechanism, the second linear actuator powering movement of the legrest mechanism.

20. The furniture member of claim 19 , further comprising a first switch controlling operation of the first actuator independently from the second actuator, a second switch controlling operation of the second actuator independently of the first actuator, and a third switch controlling simultaneous actuation of the first and second actuators.

21. The furniture member of claim 19 , wherein actuation of only the second linear actuator while the seatback frame is in the upright position to move the legrest mechanism from the retracted position to the extended position causes the seatback frame and the base frame to tilt rearward relative to the base assembly from the upright position to a pre-tilt position.

22. The furniture member of claim 19 , wherein the first and second linear actuators are aligned with each ot
