1. An impact absorption assembly for a seat back comprising:
a seat back structure; and
a wireframe structure adapted to be attached to a rear surface of the seat back structure, the wireframe structure having an upper deformation zone;
wherein the upper deformation zone deforms plastically upon an impact from a rearward direction,
wherein the deformation zone is defined by wireframe segments that are spaced apart by a distance in the rearward direction from the seat back structure, wherein upon the impact, the wireframe segments plastically deform to decrease the distance.
