Smart seats can predict a hit

Seats which can sense a crash and move away from the impact are being developed by boffins

1. Sensor activates airbag, which pushes seat away from most dangerous area
2. Hinges swing chair towards centre of car. Floor airbag helps to stiffen cabin
3. Radar fitted in door can detect an impact moments before the collision occurs

The system shields drivers and passengers from 'T-bone' smashes, the most dangerous kind of collision. Sensors trigger a side airbag, and move the seat away from danger.


	Side impacts are among the deadliest accidents for motorists and their passengers

Leading airbag maker Autoliv wants to fit radar devices in vehicle doors which can detect an impact a fraction of a second before it occurs. If the car is struck, a seatback-mounted airbag is automatically activated and swings the seat towards the centre of the cabin.

Another airbag is sandwiched in the space underneath the chair and inflates on impact to stiffen the floor. This boosts resistance and prevents crumpling.

Side impacts are among the deadliest accidents for motorists and their passengers. More than 20 per cent of all occupants killed on European roads in the last 10 years died when other vehicles hit them side on. An additional15 per cent of fatalities happened when the side of a car hit a roadside object, such as a signpost or bridge pillar.

Andrew Howard, of the AA Motoring Trust, said such hi-tech systems could help improve safety. "This is a significant area that must be addressed. It's ripe for the clever use of new technology."
