Abstract: A rollover protection system for protecting exposed gunners during ground vehicle rollovers. The system retracts the gunner into the vehicle thereby removing him/her from physical danger. The system apparatus comprises a safety harness for the gunner with a retraction mechanism that is activated upon vehicle rollover. The safety harness is attached by elastic runners to pre-loaded springs which are held in a tension mode by clamps. The springs are placed in enclosed containers mounted to the bay-floor of the vehicle. The spring clamps are released by a computer in response to a gyroscopic sensor. Shock-absorbing inflatable cushions attached to the floor under the gunner are activated to cushion the retraction.
