The Hybrid Sport from Simpson features a light-weight design using DuPont® carbon/polymer construction providing maximum comfort and maneuverability with superior strength. Hybrids come race ready. The low-profile design disappears into the seat when worn and allows for easy in and out of the race car, eliminating the danger of becoming caught in other gear. The protection stays with the racer during multiple impact, flips and rolls.
With FIA Certification – FIA 8858-2010 on Simpson Hybrid Sport, Prolite and Hybrid S sold means they do not require SFI Recertification every 5 years only Tether replacements.
The purpose of the Hybrid device is to keep the head from whipping in a crash. This prevents excessive rotational movement as a secondary protection, without otherwise restricting movement of the neck. This allows the wearer’s head to move normally but prevents or restricts head movements during a crash that would exceed the normal articulation range of the musculoskeletal system and cause severe injury. In any kind of crash the body will be decelerated by the harness with the head maintaining its velocity until it is decelerated by the neck. The device maintains the relative position of the head to the body transferring energy to the chest, torso, shoulder, seat belts, and seat as the head is decelerated.
