That stops the head whipping back-wards - a movement which can cause painful and lengthy neck injuries. The fast reaction is possible as the headrests are wired to the collision sensors which trigger the car"s airbags.

Inventor Johnson Controls - a US car seat maker which supplies GM, Toyota and Ford - has also perfected a non-explosive version which activates when the occupant"s hips are thrown against the seatback by the impact of a rear end shunt. "A lever is moved inside the seat to release the head restraint," said a spokesman. British insurers pay about í‚á£800million a year to treat whiplash victims.
