Our family have just getting into Kart and at this time just using rental Kart (SYKART and K1) for occasional track days. Initially, I am told that at the level of rental Kart performance, there is very little chance of serious injury, all that needed are just helmet. Then last week a friend spun out, hitting a wall, and broke 4 ribs. We also witnessed a head on full speed crash into a wall, the driver’s head hit the steering wheel and broke the face shield. This causes us to rethink about safety devices for use even with occasional track days. For sure we will be getting a rib protector, but also are looking hard at a neck brace. I have read many threads discussing kart neck brace, particularly two extremely well discussed threads on this forum. It seems for KART without seat belt, the data for neck brake use is inconclusive.
But for KART with seat belt, do you think it would be very helpful (at least not hurt) to use a HANS device, since just as in a race car, the body/torso is held in place by the belt, without the HANS, the head/neck will hyper-extended on impact. Would a HANS device at least does no harm in the case if a KART’s seat belt is not properly set-up, i.e not tight enough, or not anchor correctly?
Thanks so much for your time reading this and thought on using a HANS device with KART that have seat belt.
