Toyota announced the world’s first Quick Active Seat (QAS). When installed in a Lexus LS equipped with the Rear Pre-Crash Safety System, the frequency of whiplash auto crash injuries will be drastically reduced. There is radar in the rear bumper. If the system determines a crash is likely, the system first flashes the car’s brake lights to warn the driver of the approaching vehicle and then sensors implanted in the front head rests detect the positions of both front occupants’ heads and the ‘Pre-Crash Intelligent Headrests’ shift instantly to appropriate positions to reduce the risk of whiplash injury if a collision occurs. The new QAS technology takes this system a step further by additionally adjusting the seat backrests to the optimum position.
