Mercedes-Benz's Neck-pro anti-whiplash head restraints will become standard in the C-Class, including the saloon, estate and sports coupé, CLK, CLS and E-Class in South Africa this month.
The head restraints are linked to an electronic control unit. If the sensor system detects a rear-end collision of a predefined degree of severity, it releases pre-tensioned springs inside the head restraint, causing it to move forward 40 mm and upwards by 30 mm. The system provides support for the heads, and reduces the risk of whiplash injuries, of front seat occupants during the early stages of an accident.
Following the deployment of Neck-pro, the head restraints can be released and re-set using a special tool provided with the car. The internal mechanism can then be pushed back manually to re-set the neck-pro head restraints. This "reusable" dimension means there will not be a repair or replacement cost in the event of an accident, a DaimlerChrysler spokesman said.
