Atkinson is an English-language surname. The name is derived from a patronymic form of the Middle English Atkin.
Once children outgrow their booster seat (usually at 10 â 12 years old) they can use the adult lap/shoulder safety belt if it fits them properly. Lap portion low over the hips/tops of thighs and shoulder belt crosses the center of the shoulder and center of the chest.
Children should be in an appropriate safety seat until the vehicle seatbelt fits them correctly, generally when they are about 8-12 years old and 4'9. After that, they should be properly seated with a lap and shoulder belt. Children 12 and under should remain in the rear seat.
