HANS Device
|
Champ Car drivers are most severly disabled by head and neck injuries, which are less frequent
than other injuries but have devastating results. The helmets and cockpit padding help protect
Champ Car drivers from direct head impacts, but the driver’s neck still allows large head
motions, and it’s the neck that carries the impact of loads between head and torso.
The HANS Device supports the head and neck, and reduces the extreme head motions, in effect reducing the loads on the neck. |
