Abstract: A vehicle seat assembly includes a seat cushion and seat back for supporting a seat occupant. The seat back is operatively coupled to the seat cushion for selective pivotal movement between a plurality of reclined seating positions. The seat back includes a seat back frame. A head restraint is coupled to the seat back frame and defines a backset distance between the head restraint and the seat occupant's head. A mechanism operatively interconnects the seat back frame and the seat cushion for automatically tilting the seat back in response to pivotally adjusting the seat back in order to maintain the backset distance constant. When the seat back pivots rearward the seat back tilts forward, moving the head restraint toward the seat occupant's head. When the seat back pivots forward the seat back tilts rearward, moving the head restraint away from the seat occupant's head.
