  • Blast mitigating restraint system
    Patent number: 10845164
    Abstract: A torsion bar restraint system for tracked combat vehicles that aids in the improvement of occupant survival rates when associated with asymmetric threats. The blast mitigating restraint system can reduce the dynamic deflection of torsion bars based on the severity of the blast impulse as needed. Systems comprise one or more components that secure the torsion bar to the hull for protecting against dynamic deflection and lateral displacement. The two disclosed components, an end restraint device and an M-Ring restraining device, can be used in conjunction or independently from each other based on the type of threat likely to be encountered.
