摘要： A helmet restraint device for operationally securing a helmet worn by a driver, pilot, or occupant of a high-performance vehicle (such as a racecar, aircraft, or boat) to the vehicle's seat belt assembly. The helmet restraint device reduces potentially injurious forces to the occupant's head and neck during high-deceleration of the vehicle, particularly a frontal collision. The helmet restraint device includes a high strength, lightweight rod disposed behind and below the occupant's neck, just beneath the shoulder harness, and a strap that attaches between the occupant's helmet and the rod. The strap is connected to the helmet via attachments in the helmet and a cable assembly so as to allow the occupant's head to move freely from side to side. The length of the rod is sufficient to be held underneath the shoulder harness, has limited thickness to minimize interference with the occupant, yet is sufficient in size and strength to handle deceleration loads applied by the strap and shoulder harness. The strap elongates a controlled amount as the deceleration forces on the helmet, head, and neck increase, thereby allowing for controlled restraint of the occupant's head and neck. The elongation rate of the strap is tailored via the strap material's composition, weave and density.
