FIA Approved Simpson Hybrid-S Works With Three-Point Belts
The Hybrid-S Head Restraint by Simpson is the only head restraint approved for use with three-point restraints (such as standard seat belts) that is also FIA approved. This provides added protection for driving instructors, auto manufacturing test engineers, and other drivers using three-point restraints.
Simpson's Top Concern Is Safety
DE drivers and instructors can now be safe while in the student's car using only the standard three-point seat belts. Factory seat belts were not compatible with a Head and Neck Restraint until the Simpson Hybrid Nascar Approved Head And Neck Restraint became FIA approved. Stay safe in every vehicle.
Note: for the best protection while driving on a race track, we suggest a Full-Containment Cockpit System that includes a full-containment seat, Snell- or FIA-rated auto racing helmet, FIA or SFI approved Head and Neck Restraint, and six- or seven-point racing harness system.
