Your car headrest is a safety restraint, not mainly a pillow; NHTSA tests front restraints to a maximum 55 mm backset and requires them to withstand 890 newtons for 5 seconds

Car headrests serve as essential safety components designed to protect against neck injuries. They are not merely comfort features; regulations mandate their proper height and backset for optimal protection during accidents. Rigorous strength and energy absorption tests ensure these headrests can withstand high forces while keeping occupants safe. Proper adjustment is crucial to harness their full protective capabilities.
