Head RESTS
Head rests are extensions of the vehicle's seats that limit head movement during a rear-impact crash, thus, reducing the probability of a neck injury. They can also help reduce the severity of whiplash in rear-end collisions. They are aimed at protecting the head and neck. The first head rest was invented in 1921 by Benjamin Katz and was first seen in 1968 in a Volvo. They became standard car safety features in 1969. When properly installed the driver's headrest, passenger's headrest and back seat head rests reduce the risk of injury of the driver and passenger of the car by approximately 5-10%.
