MECHANISM AND CHAIR FOR POWERED COMBINED AND INDEPENDENT SEAT BACK AND LEG REST MOTION
First Claim
1. A furniture member mechanism for power combined and independent seat back and leg rest motion, comprising:
- a first actuator device connected to and electrically operated to displace a seat back member between an upright position and a fully reclined position; and
a second actuator device connected to and electrically operated to displace a leg rest member between a stowed and a fully extended position;
the mechanism selectively operated either having one of the first and second actuator devices energized while the other one of the first and second actuator devices is de-energized, or having both the first and second actuator devices energized simultaneously.

Abstract
A furniture member mechanism includes a first actuator device electrically operated to displace first and second seat back actuation links connected to and operating to rotate a seat back member between upright and fully reclined positions. A pantograph linkage set connected to a leg rest member is at least partially supported in an extended position by rotational contact with a support rod. A second actuator device identical to the first actuator device is electrically operated to axially rotate a drive rod connected to a drive link. The drive link is connected to and displaces the pantograph linkage set between the stowed and extended positions. A swing lever rotatably connected to the support rod is rotated during operation of the second actuator device to extend the pantograph linkage set. The swing lever in a fully rotated position displaces the support rod creating a furniture member tilt position.

27. A furniture member, comprising:
-
a furniture frame assembly rotatably connected to a base member; a rocker spring assembly connected to each of the furniture frame assembly and the base member permitting a rocking motion of the furniture frame assembly with respect to the base member; and a mechanism, including; a first actuator device electrically operated to displace first and second seat back actuation links connected to and operating to rotate a seat back member between an upright position and a fully reclined position; a pantograph linkage set connected to a leg rest member, the pantograph linkage set at least partially supported in an extended position by rotational contact with a support rod, the support rod connected to opposite first and second side members of the furniture frame assembly; and a second actuator device identical to the first actuator device and electrically operated to axially rotate a drive rod connected to at least one drive link, the drive link connected to and displacing the pantograph linkage set between a stowed and the extended positions. - View Dependent Claims (28, 29, 30, 31, 32, 33, 34)
