About Air Protect® : The Air Protect system works to protect your child in two vital ways. In a side impact collision, air protect immediately safeguards your child by diminishing the forces of the crash. In a second layer of defense, the system allows air to escape from the headrest: channeling more crash energy away from your child. It is this double layer of protection that makes air protect technology unique.
