Abstract

A seat assembly forming a substantially horizontal plane for an exposed surface of each of a lower seat cushion and a seatback cushion of a seatback comprises a lifter mechanism for a rearward edge of the lower seat cushion. The lifter mechanism comprises a bracket pivotable about a transverse bar fixedly mounted to a frame assembly for a lower seat assembly, the bracket comprising a forward lever and a rearward lever; and a link pinned at a first end to the seatback and pinned at a second end to the rearward lever by a slot. The rearward edge of the lower seat cushion is initially raised by the forward lever upon the seatback pivoting to a predetermined reclined position and the rearward edge of the lower seat cushion is raised to the substantially horizontal plane upon the seatback pivoting to a fully reclined position.

First claim

We claim:

1. A seating assembly comprising a lifter mechanism for an edge of a seat cushion, the lifter mechanism comprising a bracket pivotable about a transverse bar, the bracket comprising a forward lever and a rearward lever, and a link pinned at a first end to a seatback and pinned at a second end to the rearward lever via a slot, wherein the forward lever raises the edge upon the seatback pivoting to a predetermined reclined position;
wherein the slot has an upper end and a lower end and the rearward lever of the bracket comprises a pin received within the slot, wherein the lower end of the slot being proximate with the pin corresponds to an upright position of the seatback and wherein the upper end of the slot being in initial contact with the pin corresponds to the predetermined reclined position between an upright position and a fully reclined position; and
wherein each of the seat cushion and the seatback have an exposed surface and wherein the exposed surfaces of each of the seat cushion and the seatback substantially occupying the same horizontal plane when the seatback is in the fully reclined position.

2. The seating assembly of claim 1 , wherein pivoting the seatback between the predetermined reclined position and the fully reclined position urges the upper end of the slot against the pin to rotate the bracket and raise the forward lever and the edge of the seat cushion upwardly.

3. The seating assembly of claim 1 , wherein the predetermined reclined position is about 55.5° relative a vertical plane.
