Simpson Hybrid S Carbon FHR Device – 3-Point Belt Compatible

The Simpson Hybrid S is an extraordinary breakthrough in motorsport safety engineering, standing as the only Frontal Head Restraint (FHR) on the market proven effective and certified for use with standard 3-point seatbelts. Developed in direct collaboration with major Detroit automotive manufacturers and subjected to rigorous third-party crash testing, this specialist device finally allows high-performance driving instructors, commercial test engineers, and track day enthusiasts driving bone-stock road cars to access professional-grade neck and head protection without needing to install a full roll cage and race harness.

Handcrafted from ultra-lightweight, high-tensile carbon fibre, the Hybrid S uses a sophisticated multiple-load-path chassis. During a severe forward impact, it dynamically captures and distributes extreme head forces away from the neck, significantly reducing fatal tension loads even when anchored only by a standard road-car seatbelt. The sleek back and shoulder support layout is carefully contoured to maximize physical contact with standard automotive seats, improving overall comfort during long coaching sessions or development testing. Featuring a simple front buckle attachment system, it completely eliminates bulky, uncomfortable under-arm straps while keeping your upper chest and collarbone entirely free.

Key Features:

• 3-Point Seatbelt Compatibility: The world's only FIA and SFI certified FHR system tested and proven to dramatically reduce neck strain when used alongside standard 3-point factory road belts.
• Premium Carbon Fibre Build: Constructed from elite structural carbon composites to keep the device exceptionally lightweight on your shoulders while maintaining maximum structural rigidity.
• Advanced Multiple Load Paths: Engineered to split and route crash forces through several distinct vectors, protecting the spine and neck under sudden deceleration.
• Ultra-Low Profile Chassis: Built with an incredibly flat rear profile—completely removing the high, rigid back found on traditional HANS yokes that can dangerously snag on roll bars or door frames during a rapid exit.
• Integrated Belt Anchor System: Sculpted shoulder channels safely guide and control the path of the seatbelt webbing, preventing the vehicle's factory shoulder belt from sliding off the device under load.
• International FIA 8858-2010 Certification: Fully approved for international motorsport use, providing seamless compliance across global logbook events when upgraded to full race harnesses.

Technical Specifications:

Important Safety Note from Simpson: While the Hybrid S offers a massive leap forward in track-day protection for cars with factory road belts, driver and instructor safety remains our highest priority. For absolute optimal protection during dedicated competitive track use, we strongly recommend a complete cockpit safety system consisting of an FIA-approved full-containment race seat, an FIA-rated helmet, a 6-point competition harness, and an FHR device.

Sizing Guide (Chest Measurement):

To ensure an accurate fit, measure your chest circumference around the widest point while wearing your typical track apparel or racing layers.

Frequently Asked Questions (FAQs):

• Can I use this device in my dedicated race car with a full 6-point harness?
• Yes, absolutely. The Hybrid S is a highly versatile device. It was specifically engineered and crash-tested to excel with 3-point road belts, but it is fully certified to FIA 8858-2010 for international motorsport, meaning you can step out of a standard road car and strap directly into a full-containment race seat with a 6-point harness without needing to switch devices.
• Do I need a special helmet to use the Hybrid S?
• No, any helmet officially certified to Snell (SA2015 / SA2020) or FIA (8859 / 8860) standards that features standard M6 threaded inserts for FHR posts will work perfectly. The device comes pre-fitted with standard HANS tethers that slide directly onto standard HANS helmet posts.
• Can this device be upgraded to a quick-release tether system?
• Yes. If you prefer an instant pull-cord release instead of sliding metal plates, the standard tethers on the Hybrid S can be easily swapped. You can purchase the Simpson Hybrid Quick Release Sliding Tethers and matching M61 Helmet Anchors separately at any time.
