Abstract

A motor vehicle seat frame assembly has a headrest movable between an extended position and a retracted position. The frame assembly comprises a seatback frame operatively engaged with the headrest, a cable, and a rod having an extension. The seatback frame is pivotable from a use position to a lowered position, while the cable extends between the headrest and a fixed point. A tensioner is attached to the seatback frame, and is adapted to wind the cable on the extension when the seatback frame is pivoted toward the lowered position.
