ABSTRACT:
An automotive seat assembly for use in the passenger compartment of an automotive vehicle comprising a seat portion, a seat back portion, and an adjustable back support system, the back support system controlling movement of the seat back about a relatively fixed seat track whereby backward tilting movement in response to forwardly directed high acceleration forces on the vehicle body will trigger an adjustment mechanism for a headrest carried near the upper margin of the seat back whereby the motion of the headrest relative to the passenger compartment is substantially reduced compared to the angular motion of the seat back when the seat back is moved by the acceleration forces in a rearward direction.
