Abstract
A seating-unit mechanism includes various components that control a position of the seat and backrest and that control an extension and retraction of an ottoman and footrest. For example, the mechanism includes a linear actuator that controls a seat pitch (e.g., height and level of recline). In addition, the mechanism includes an ottoman-linkage drive mechanism, which might include a drive link or another linear actuator.
Claims13
A mechanism for adjusting seating positions of a seating unit, the mechanism comprising:
- a pair of side rails;
- a pair of mirror-image linkage mechanisms, each of which is attached to respective side rail and each of which comprises:
- a front pivot link and a rear pivot link pivotably coupled to the respective side rail,
- a seat plate pivotably coupled to the front pivot link and the rear pivot link,
- an ottoman front pivot link and an ottoman rear pivot link pivotably coupled to the seat plate, and
- a rear drive tube extending between and coupled to both rear pivot links of the mirror-image linkage mechanisms;
- a linear actuator coupled to the rear drive tube that controls a position of the rear pivot links;
- and
- one or more ottoman-linkage drive mechanisms operatively coupled to the ottoman front pivot links of the mirror-image linkage mechanism, the one or more ottoman-linkage drive mechanisms controlling extension and retraction of an ottoman, wherein the one or more ottoman-linkage drive mechanisms include a second linear actuator coupled at one end to another rear drive tube extending between the seat plates and coupled at another end to a front drive tube coupled between the ottoman front pivot links.
