1. A vehicle seat assembly comprising: a seat bottom; a seat back pivotally attached to the seat bottom and including a track having a longitudinal track axis; a head restraint moveably attached to the track such that the head restraint is moveable longitudinally along the track from a use position to a stowed position; and an actuation device associated with the head restraint for moving the head restraint from the use position toward the stowed position when the seat back pivots toward the seat bottom, the actuation device including a rotatable member and a link rod having a first end coupled to the rotatable member and a second end coupled to the head restraint, the link rod being configured to transfer rotational motion of the rotatable member into linear motion of the head restraint, an engagement member connected to the seat bottom, and a gear connected to the seat back, the gear being configured to engage the engagement member and rotate as the seat back pivots with respect to the seat bottom, thereby causing the head restraint to move from the use position toward the stowed position.
