HEADREST POSITION DURING NORMAL DRIVING: IMPLICATIONS TO NECK INJURY RISKS IN REAR CRASHES

The gap and relative height of headrest behind drivers were determined for 1,915 vehicles approaching an intersection on a two-lane road. Vehicle type and headrest adjustment were also evaluated in film of normal driving taken by the Insurance Institute for Highway Safety. Only 10 percent of drivers had headrests in the most favorable position to prevent neck extension during a rear-end crash. Seventy-three percent of cars had adjustable headrests, but only a quarter were placed in the up position. Eighty-three percent of the adjustable headrests could have been raised to better protect the driver. Hyge sled tests were run to determine biomechanical responses for the various conditions observed in normal driving. This included three headrest heights and three gaps behind the head.
