ABSTRACT:
A vehicle seat assembly is provided with an energy absorption mechanism for dissipating energy in a high energy impact. The assembly includes a seat with a seat back totally connected thereto. The seat back includes a first support member pivotally connected with respect to the seat and a second support member pivotally connected to the first support member. An energy absorption mechanism is positioned between the first and second support members for dissipating energy as the second support member pivots with respect to the first support member. The energy absorption mechanism includes a plurality of adjustable shear pins having shearable cross-sections of various sizes to facilitate adjustment based upon the seat back angle. The shear pins are movable in a plurality of slots sequentially increasing in length such that the shear pins will sequentially shear to dissipate energy over time as the respective shear pins reach the end of their respective slots.
