ABSTRACT:
A seat assembly includes a seat back frame pivotally coupled to a seat cushion for movement between a plurality of reclined seating positions and a fold flat position. A linkage includes first and second links having proximal ends pivotally coupled by a link pin. The first link includes a distal end pivotally coupled to the seat back frame. A control link is coupled at a first end to the link pin and at a second end to the seat cushion. A side bolster is pivotally coupled at an upper end to the seat back frame and at a lower end to a distal end of the second link. Pivoting of the seat back frame between the seating and fold flat positions urges the side bolster between a deployed position extending away from the seat back frame and a retracted position adjacent the seat back frame.
