booster seatA vehicular safety device used for children who are too large for a safety (baby) seat and too small to wear a shoulder seat belt. Booster seats generally lift the child by 10 to 15 cm, allowing the three-point seat belt to cross the child at the shoulder and hips. Improperly fitted belts may ride across the stomach and neck, causing internal injuries.
