Disclosed are embodiments of passenger seats equipped with seat belts for mitigating seat damage and spinal tension from free-flail movements. In embodiments, the assembly includes a seat back, a first slip ring positioned proximate a top of the seat back, a second slip ring positioned lower on the seat back, a retractor, and a webbing threaded through each of the first and second slip rings. During normal use of the seat the first slip ring forms a first pivot for the webbing, and during a qualifying deceleration event the second slip ring forms a new pivot for the webbing lower on the seat back. In a further embodiment, first and second webbings form primary and auxiliary restraints guided by respective first and second pivots.
