BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The invention relates to a seat assembly having a moveable head restraint. [0003] 2. Background Art [0004] Vehicle seat assemblies may be provided with moveable head restraints. U.S. Pat. No. 6,192,565, for example, discloses a seat assembly having a retractable head restraint. SUMMARY OF THE INVENTION [0005] Under the invention, a new seat assembly is provided. In one embodiment, the seat assembly includes a seat bottom and a seat back pivotally attached to the seat bottom. The seat back includes a track having a longitudinal track axis. The seat assembly further includes 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. An actuation device is 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. [0006] In another embodiment, the seat assembly includes a seat bottom and a seat back pivotally attached to the seat bottom. The seat back includes a track having a longitudinal track axis. The seat assembly further includes a head restraint moveably attached to the track such that the head restraint is moveable longitudinally along the track between a use position and a stowed position. An actuation device is associated with the head restraint for moving the head restraint from the stowed position toward the use position when the seat back pivots away from the seat bottom. [0007] While exemplary embodiments in accordance with the invention are illustrated and disclosed, such disclosure should not be construed to limit the claims. It is anticipated that various modifications and alternative designs may be made without departing from the scope of the invention. BRIEF DESCRIPTION OF THE DRAWINGS [0008] FIG. 1 is a side perspective view of a vehicle seat assembly according to the invention, wherein the seat assembly includes a seat bottom, a seat back pivotally attached to the seat bottom, and a head restraint moveable attached to the seat back, and wherein the seat back is shown in a raised position and the head restraint is shown in a use position; [0009] FIG. 2 is a side perspective view of the seat assembly of FIG. 1, showing the seat back in a dumped or lowered position and the head restraint in a stowed position; [0010] FIG. 3 is a schematic view of the seat assembly showing an actuation device for moving the head restraint along a track of the seat back, wherein the head restraint is shown in the use position; [0011] FIG. 4 is a schematic view of the seat assembly showing the head restraint in the stowed position; [0012] FIG. 5 is an enlarged perspective view of a portion of the seat assembly showing first and second posts of the head restraint connected to a carrier having a carrier body and a retainer member; [0013] FIG. 6 is an enlarged perspective view similar to FIG. 5 with the carrier body removed to show the retainer member; [0014] FIG. 7 is a schematic view of a portion of the seat assembly showing a gear arrangement of the actuation device, wherein the seat back is shown in the raised position and a gear of the gear arrangement is shown in a first position; [0015] FIG. 8 is a schematic view similar to FIG. 7 and showing the seat back in the lowered position and the gear in a second position; [0016] FIG. 9 is a rear view of the gear arrangement; and [0017] FIG. 10 is a schematic view of the seat assembly showing a second embodiment of the actuation device. DETAILED DESCRIPTION [0018] The following description is merely exemplary in nature, and is in no way intended to limit the invention or its application or uses. [0019] FIG. 1 shows a vehicle seat assembly 10 according to the invention mounted on a floor 12 of a motor vehicle 14. The seat assembly 10 includes a seat bottom 16 moveably mounted to the floor 12, a seat back 18 pivotally attached to the seat bottom 16, a head restraint 20 moveably attached to the seat back 18, and a dump mechanism 22 for allowing the seat back 18 to pivot with respect to the seat bottom 16. [0020] The dump mechanism 22 may have any suitable configuration for allowing pivotal movement of the seat back 18. For example, the dump mechanism 22 may include a latch (not shown) connected between the seat bottom 16 and seat back 18, a lever 23 for releasing the latch, and a spring (not shown) engaged with the seat back 18 for urging the seat back 18 toward the seat bottom 16 when the latch is released.
