ABSTRACT:
A motor driven recliner chair in which a power transfer or drive tube is rigidly connected to the linkage actuating arms and operationally connected to the power screw of the motor by a nut threaded on the screw and slidably but non-rotatably positioned in the drive tube. A spring-biased latching member is pivotally mounted on the drive tube and captively retains the nut in the power screw-engaged position. The latching member may be withdrawn by the chair occupant whereupon the power drive is effectively disengaged and the chair may be manually operated to quickly return to the upright position.
