MECHANISM AND CHAIR FOR POWERED COMBINED AND INDEPENDENT SEAT BACK AND LEG REST MOTION

摘要

A furniture member mechanism (26) includes a first actuator device (28) electrically operated to displace first and second seat back actuation links connected to and operating to rotate a seat back member (16) between upright and fully reclined positions. A pantograph linkage set connected to a leg rest member (24) is at least partially supported in an extended position by rotational contact with a support rod (64). A second actuator device (30) identical to the first actuator device is electrically operated to axially rotate a drive rod (56) 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 (134) 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.
