In the event of a rear impact, whiplash-minimising front seats protect the necks of the driver and front passenger.
The headrests are optimally sized and positioned with a forward tilting stance to minimise the distance between the occupants head and the head rest.
By minimising the distance that the head and neck have to travel before reaching the head rest, the load or force on the neck is less and therefore helps to minimise whiplash injury.
Simultaneously, the seatback is designed to permit rearward movement of the occupants torso. Together, these reduce the loading on an occupant's neck by up to 40% compared to a conventional seat design.
