Abstract
A vehicle seat assembly includes a seat pan and four linkage arms individually pivotably coupled with the seat pan. The assembly further includes a mounting plate, each of the four linkage arms being pivotably coupled therewith. A gear rack is coupled with the seat pan and defines an articulation path therefor, and a pinion is operably engaged with the rack to drive articulation of the seat pan including pivoting of the four linkage arms and sliding of the mounting plate.

A vehicle seat assembly, comprising:
- a seat pan;
- four linkage arms individually pivotably coupled with the seat pan;
- a mounting plate pivotably coupled with each of the four linkage arms;
- a gear rack coupled with the seat pan and defining an articulation path therefor;

A motor vehicle seat, comprising:
- a base platform;
- a cushion;
- and
- a mounting assembly including:
- a linkage mechanism slidably mounted on the base platform and coupled with the cushion;
- and
- a drive mechanism coupled between the base platform and the linkage mechanism and defining a movement path for the cushion with respect to the base platform including articulation about the linkage mechanism and sliding of the linkage mechanism with respect to the base platform, the drive mechanism including a rack coupled with the linkage mechanism and defining the movement path and a pinion coupled with the base platform and operably engaged with the rack to drive the articulation of the cushion about the linkage mechanism and the sliding of the linkage mechanism with respect to the base platform.
A mounting assembly for a vehicle seat cushion comprising:
- a cushion support defining a front and a back;
- a mounting plate underlying the support between the front and the back, and having a plate track portion coupled thereto;
- a front linkage arm having a first length and coupled between the mounting plate and the cushion support adjacent the front;
- and
