Methods and apparatus are provided for a hold-down assembly for attaching an armor panel to the floor of a vehicle utilizing an existing integrated tie-down feature. The assembly includes a base member positioned underneath the tie-down feature and aligned with a through-hole in the panel. A top positioned over both the base member and the hole in the panel at least partially overlaps the panel around the hole. A fastener extending through the top and into the base is adapted to pull the top down onto the panel, holding the panel against the floor of the vehicle.

1. An apparatus for attaching a panel to an interior surface of a vehicle, the interior surface having at least one cut out that receives an attachment feature that includes a cup attached to the cut out and a tie down attachment member mounted to the cup, the apparatus comprising: a base member positioned within the cup and adapted to support the attachment member, and being aligned with a hole in the panel when the panel is positioned against the surface;a top positioned over the panel to overlap the panel around the hole;a fastener connecting the top to the base member adapted to pull the top down onto the panel and hold the panel against the interior surface. 2. The apparatus of claim 1, wherein the panel is armor plating. 3. The apparatus of claim 2, wherein the vehicle is an aircraft. 4. The apparatus of claim 3, wherein the tie down attachment member is a cargo tie-down ring, and the tie-down ring is trapped between the base and the top. 5. The apparatus of claim 4, wherein the fastener is a bolt inserted down through a hole in the top and screwed into a threaded hole in the base. 6. The apparatus of claim 4, wherein the base is generally circular and has a groove to receive the tie-down ring such that, when seated, a substantial portion of the tie-down ring is within the groove and below the top surface of the base. 7. The apparatus of claim 1, wherein the top includes a recessed cylindrical portion projecting into the hole in the panel, and a perimeter flange portion overlapping the panel around the hole. 8. The apparatus of claim 7, further comprising a gasket between the perimeter flange portion of the top and the panel. 9. The apparatus of claim 1, wherein the inside surface of the vehicle is a floor. 10. The apparatus of claim 5, wherein the bolt further comprises a D-ring. 11. A method of attaching a panel to an interior surface of a vehicle, the interior surface having a cut out that receives an attachment feature that includes a cup attached to the cut out and a tie down attachment member mounted to the cup, the method comprises the steps of: positioning a base member within the cup for supporting the attachment member;positioning the panel against the interior surface so that a hole on the panel is aligned with the attachment feature and the base member;covering the hole in the panel with a top that overlaps the panel around the hole;inserting a fastener through an aperture on the top and connecting the fastener to the base member; andtightening the fastener to pull the top down onto the panel to clamp the panel between the top and the interior surface of the vehicle and trap the attachment feature between the base and the top. 12. The method of claim 11, wherein the existing attachment feature comprises a tie-down ring pivotable between a stowed position within the cup, and an open position with the ring substantially out of the cup. 13. The method of claim 12, wherein the step of positioning the base member within the cup for supporting the attachment member comprises the steps of: positioning the base within the cup with the tie-down ring in the open position; andpivoting the tie-down ring onto the base. 14. The method of claim 11, wherein the panel comprises ballistic armor, the vehicle is an aircraft, and the interior surface of the vehicle is the floor. 15. A hold-down assembly for attaching an armor panel to the floor of a vehicle, the floor having a cutout that receives an attachment assembly that includes a cup attached to the cutout and a pivotable cargo tie-down ring mounted to the cup, the assembly comprising: a base member positioned underneath the tie-down ring and aligned with a through-hole in the panel when the panel is positioned against the surface;a top positioned over both the base member and the hole in the panel, the top overlapping the panel around the hole; anda bolt extending through a hole in the top and threaded into the base, the assembly configured such that tightening the bolt pulls the top down onto the panel, thereby holding the panel against the floor of the vehicle. 16. The hold-down assembly of claim 15, wherein the vehicle is an aircraft. 17. The hold-down assembly of claim 15, wherein the base is generally circular and has a groove to receive the tie-down ring such that, when seated, a substantial portion of the tie-down ring is within the groove and below the top surface of the base. 18. The hold-down assembly of claim 15, wherein the top includes a recessed cylindrical portion projecting into the hole in the panel, and a perimeter flange portion overlapping the panel around the hole. 19. The hold-down assembly of claim 18, further comprising a gasket between the perimeter flange portion of the top and the panel. 20. The hold-down assembly of claim 15, wherein the bolt further comprises a pivotable D-ring.
