What is a HANS device?
HANS is a registered trademark for Frontal Head Restraints (FHR) and has become a brand name synonymous with this type of device, much like vacuum cleaner being knows as ‘Hoovers’. FHR devices were developed for motorsport use to reduce the risk of neck and spine injuries in the event of a crash and work by limiting the forward movement of the head in relation to the body. The weight of your head plus a helmet can have a devastating effect in a high impact often resulting in Basilar skull fractures. This type of injury is not uncommon in motorsport and has claimed the lives of many top competitors including Roland Ratzenberger and Dale Earnhardt senior who may still be with us if FHR’s were in use at the time.
Proven to save lives Frontal Head Restraints use the cars harness to anchor the device securely to upper body. Tethers attach to the helmet reducing forward travel but still allowing sufficient movement for comfort and visibility. Special anchor points often referred to as ‘posts or ‘clips’ are required on the helmet to allow attachment of the FHR tethers. Most motorsport specific helmets supplied already include the posts or at least have the provision to fit them. If you are unsure if your helmet is compatible then give our experts a call and we will advise.
Are some FHR systems / HANS Devices better than others?
All FHR devices are designed to offer the same level of protection and every device on offer from Demon Tweeks complies with FIA homologation. The main difference between them is the materials they are made from. Some are manufactured from carbon fibre and are lighter weight then other devices, a desirable feature if you will be wearing it for long periods of time or if you are looking to keep weight to a minimum.
Which FHR device do I need?
HANS and FHR devices are available in a range of sizes and reclines to suit various racing applications. The reason for differing reclines is to ensure that the device sits comfortably and securely on the body, whatever the seating position. 10, 20, 30, 40 degree and adjustable devices are available with 10 degree being for upright seating positions such Sprintcars and Midgets. 20 degree is generally suited to any sedan or rally car application. 30 degree is the choice for most single seater and sports cars whilst 40 degree is generally used in Formula 1. This is a guide only and we recommend that you check the required recline for your application before you purchase.
What is a Hybrid FHR system?
Rather than using the established over-the-shoulder harness method of securing the head, a new breed of FHR Systems from Simpson Motorsport uses an innovative series of straps around the torso to provide protection not only in the fore and aft directions, but also against side impacts – where the head is most likely to be forced left or right. This is of particular interest to drivers of saloon and rally cars – where side impact protection for the head is often limited when compared to a single-seater formula car.
