Abstract
A linkage that provides a fully flat reclined position is described. The linkage includes a full-flat lift link pivotally coupled to a seat support link. A backrest support link couples to the lift link through an oblong aperture to provide additional range of motion. The lift link includes a laterally extending flange, the perimeter of which acts as a cam surface for a cam pin that obstructs reclining of the backrest support link when the rocker-recliner is in an upright position. When fully reclined, the linkage configures a footrest, seat portion, and backrest portion in a generally equal plane to provide a fully flat seating surface.
Claims19
A linkage for use in reclining furniture comprising:
- a seat support linkage that includes a seat support link, a connecting link having a cam pin disposed proximate a forward end, and a full-flat lift link rotatably coupled to the seat support link at a pivot point located between a first end and a second end of the full-flat lift link, the first end including a laterally extending flange that provides a cam surface for engaging the cam pin and the second end including an elongated aperture for coupling to a backrest support link;
- and
- a backrest linkage including the backrest support link coupled to the second end of the full-flat lift link, wherein the pivot point of the full-flat lift link is positioned such that rearward rotation of the backrest linkage causes the second end of the full-flat link to rotate upward and a rearward portion of the seat support link to rotate upward.
A three-position reclining seating unit configurable to a full-flat recline position via a linkage disposed therein, the linkage comprising:
- a seat support linkage that includes a seat support link, a connecting link having a cam pin disposed proximate a forward end, and a full-flat lift link rotatably coupled to the seat support link at a pivot point located between a first end and a second end of the full-flat lift link, the first end including a laterally extending flange that provides a cam surface for engaging the cam pin and the second end including an elongated aperture for coupling to a backrest support link;
- an ottoman linkage pivotally coupled to the seat support linkage that extends a footrest from a front portion of the seating unit when the seating unit is moved from an upright position;
- a backrest linkage including the backrest support link coupled to the second end of the full-flat lift link;
- a seat portion at least partially supported by the seat support link;
- and
- a backrest portion at least partially supported by the backrest support link, wherein the pivot point of the full-flat lift link is positioned such that rearward rotation of the backrest linkage causes the first end of the full-flat link to rotate downward and a rearward portion of the seat support link to rotate upward.
A linkage for use in a seating unit, the linkage comprising:
- a seat support link having a forward linear section and a rearward linear section;
- a full-flat lift link rotatably coupled to the seat support link at a pivot point located between a first end and a second end of the full-flat lift link, the second end including an elongated aperture;
- a connecting link having a cam pin disposed proximate a forward end, wherein the first end of the full-flat lift link includes a laterally extending flange that provides a cam surface for engaging the cam pin;
- and
- a backrest support link coupled to the second end of the full-flat lift link via the elongated aperture and to the rearward linear section of the seat support link.
