Problems solved by technology

[0007] Furthermore, traditional motorized adjustments of complex linkages often result in out-of-sequence movement of the seat unit's stool and backrest
For example, when adjusted from a closed position to an extended position, the pressure of the user's legs on the stool may cause resistance to extending the footrest assembly

Embodiment Construction

[0033]The subject matter of embodiments of the invention is described herein with such features as to satisfy statutory requirements. The description itself is not intended, however, to necessarily limit the scope of the claims. Rather, the claimed subject matter can be implemented in other ways including different elements or combinations of elements similar to those described in this document, in conjunction with other prior or future technologies.

[0034] Figure 1-3 A portion of a seating unit 10 is shown, which is in figure 1 is shown in the closed position, the figure 2 is shown in the extended position (TV position), while in image 3 is shown in the reclined position. For illustrative purposes, Figure 1-3 Only some of the elements that may be included in the seating unit 10 are shown, while various other possible components have been omitted. Generally, the seating unit 10 has a seat substructure 12, a backrest substructure 14, a linkage mechanism 100, a first...

Abstract

The present invention provides a seat unit. The seat unit includes a linkage mechanism adapted to adjust between closed, extended, and reclined positions. The linkage mechanism includes a seat-mounting plate mounted to a footrest assembly, a back-mounting link and a rear bellcrank both rotatably coupled to the seat-mounting plate, an activator bar that controls a footrest drive link, and a linearactuator for performing automated adjustment of the linkage assembly. In operation, a stroke in a first phase of the linear actuator generates a torque on the activator bar. The footrest drive link converts the torque into a laterally-directed force that pushes the footrest assembly into the extended position. A stroke in the second phase acts to push the activator bar forward and translate the seat-mounting plate forward at a consistent inclination angle. The forward translation causes the rear bellcrank to rotate, thereby biasing the back-mounting link rearward into the reclined position.

Description

[0001] This application is a divisional application of an invention patent application with an application date of October 28, 2014, an application number of 201480006053.2, and an invention title of "Zero Wall Gap Linkage Mechanism for Providing Additional Layout". technical field [0002] The present invention generally relates to a mobile decorative piece of furniture designed to support a user's body in a substantially fixed position. Movable upholstery furniture includes recliners, reclining chairs, sofas, loveseats, sectional sofas, theater seating, traditional seating, and seating with movable seating portions, which are collectively referred to herein as "seating units." More particularly, the present invention relates to an improved linkage mechanism developed to accommodate a wide variety of seating units otherwise defined in the art by the configuration of the linkage mechanism. Furthermore, the improved linkage mechanism of the present invention enables reclining o...
