Automatic positioning device for seat unit

Abstract

An automatic positioning device for a seating unit includes a motor assembly configured to move a linkage assembly through a series of positions that arranges the seating unit in a stowed position, an open position, or an extended position. The motor assembly connects directly to the ottoman drive linkage via mounting tubes. Furthermore, the motor assembly may be connected to the base rail of the seating unit or to the rear pivot link by means of a rear mounting tube.

Description

Background technique [0001] Furniture traditionally referred to as "zero wall clearance" furniture are those articles of furniture such as lounge chairs, wherein the back of the chair can be placed close to a wall of a room such that when the chair is moved from its initial or normal closed or upright position to its In the fully open reclined position, the entire body of the chair moves forward to allow the seat back and headrest portions of the chair to recline without having to contact the wall so that the wall does not obstruct its transition from the initial or normal stowed or upright position Move to its fully open reclined position. [0002] The Zero Wall Clearance Chair can be manually operated or motorized. However, adjusting the seating unit creates significant forces, stresses and torques on the drive components. Also, the chair part sometimes moves as the seat part (relative to the base track), which changes the balance of the chair and creates some instability....
