A rollover mitigation device for a motor vehicle comprises a frame mounted to a roof assembly within which is disposed a transversely mounted deployable rollover protector shaft. The frame comprises a pair of lateral mounting rails mounted to the roof assembly and a tubular cross member extending between the pair of lateral mounting rails. The deployable rollover protector shaft is substantially disposed within the tubular cross member when in the stowed position and is actuated from the stowed position to a locked deployed position by a spring disposed within the tubular cross member. A controller actuates a release lock to release the deployable rollover protector shaft to the deployed position upon a sensor detecting a roll angle of the motor vehicle exceeding a predetermined value. A deployment lock restrains the deployable rollover protector shaft in the deployed position.
