NECK-PRO: increased protection of cervical vertebrae
Action areas for safety systems are derived principally from the intensive accident research carried out since 1969. The development of NECK-PRO head restraints for passenger cars, for example, is likewise based on analyses of real-life accidents. NECK-PRO reduces the risk of whiplash injuries in the event of a rear impact. These injuries, caused by the sudden jolting movement of the head and the resulting strain on the cervical vertebrae, are one of the most common types of accident injury in Europe.
NECK-PRO is a sensor-controlled, crash-responsive head restraint which is activated when a rear impact is detected. If the sensors detect a rear-end collision of a certain, pre-defined severity, they activate preloaded springs inside the head restraint. These springs then help to push the padded areas of the head restraints forwards by about 40 millimetres and upwards by 30 millimetres within a matter of milliseconds to support the heads of the front passengers at an early stage and help to prevent overbending of the cervical vertebrae. | ||||||||
