An aircraft seat assembly (100) including stanchions (112) defining elongated guide channels (120) and elongated motion sleds (116) nested in the guide channels and affixed to a seat bucket (104). An energy absorber (124) implemented as a wire bender assembly is coupled between the stanchions and the motion sled. In use, the elongated guide channels guide motion of the motion sleds and the wire bender assemblies attenuate energy during a dynamic event exceeding a predetermined threshold load value. The elongated interface between the guide channels and motion sleds serve to transfer excessive loading to the seat frame thereby protecting the seat assembly from damage and the occupant from excessive lumbar spinal loads.
