US Patent 10495419 Vehicle armor systems and methods

A vehicle includes a frame, front cabin, and an armor component. The vehicle is reconfigurable between a B-kit configuration where the armor component is coupled to the vehicle, and an A-kit configuration where the armor component is removed. The armor component is configured to be coupled to at least one of a plurality of bosses disposed on a front wall or a side wall of the vehicle. A vehicle may also include at least two frame rails, a support, and a spacer that is coupled to at least one of the frame rails and the support. The armor component may replace the spacer in the B-kit configuration. The armor component may be an underbody armor panel. The vehicle may further include a retainer to simplify the conversion between the A-kit and a B-kit configurations and a step.
