Embodiment Construction

[0024] Figure 1-3 A seating unit 10 is shown. The seating unit 10 has a seat 15, a backrest 25, a leg 26 (such as a support sleeve), a linkage 100 or 1000, a first footrest bed 45, a second footrest bed 47, a stationary base 35 and a pair of opposite arm 55 . The stationary base 35 has a front portion 52, a rear portion 54, and is supported by legs 26, wherein the legs 26, such as sleeves, support the stationary base 35 and lift it above an underlying surface (not shown). Furthermore, the stationary base 35 is interconnected to the seat 15 via a linkage 100 or 1000 arranged substantially between the pair of opposite arms 55 and the rear 54 . During adjustment of the seating unit 10 , the seat 15 can move over the stationary base 35 when swinging the rocker mechanism of the linkage mechanism 100 or when shifting the slide assembly of the linkage mechanism 1000 . In an embodiment, the seat 15 or backrest 25 can move according to the arrangement of the linkage 100 or 1000 so ...

Abstract

Rocker-recliner-style and glider-recliner-style seating units that include linkage mechanisms for adjusting the respective seating units between closed, extended, and reclined positions are provided. The seating units are each powered by a linear actuator that facilitates automated adjustment of the respective linkage mechanisms. This adjustment of the linear actuator is sequenced into a first phase and a second phase. A stroke of the linear actuator in the first phase acts to adjust a linkage mechanism between the closed and extended positions by extending or retracting ottoman(s) attached to a footrest assembly. A stroke in the second phase acts to adjust a linkage mechanism between the extended and reclined positions by translating a seat-mounting plate forward or rearward at a consistent inclination angle while, concurrently, tilting a back-mounting link. Accordingly, the phase sequencing ensures that each linkage mechanism commences adjustment within the second phase only once the first-phase adjustment is substantially complete.

Description

technical field [0001] The present invention relates generally to motion upholstery furniture designed to support the body of a user in a substantially sitting position. Sports upholstery furniture including recliners, incliners, sofas, loveseats, modular furniture, theater seating, traditional chairs, and chairs with movable seats, collectively referred to herein as "seating units" . More specifically, the present invention relates to an improved linkage developed to accommodate seating units used as rocking or sliding recliners. Thus, the improved linkage mechanism of the present invention provides recline for the seating unit while accommodating the operation of the rocker mechanism or slide assembly. Background technique [0002] There are reclining seating units that allow the user to extend the footstool or ottoman forward and recline the backrest relative to the seat. These existing seating units typically provide three basic positions: a standard non-recline stowe...
