A new military seat energy absorption system has been designed. This system consists of specific springs and dampers under the seat, as well as an optimized seat cushion with specific properties. The system also utilizes a "sigma bracket" beneath the seat system that will plastically deform during an explosion event and absorb a predetermined amount of energy. The springs, dampers, and seat cushion, when coupled with the sigma bracket, will protect an occupant from excessive accelerations during an under-carriage explosion. The system can also reset within a second to be ready to absorb and dissipate the second impact as the vehicle returns to the ground.
