ISOFIX is an international standardized fitting system, which provides the safest, easiest and quickest way to install a child car seat correctly without the need of vehicle seat belts. The name ISOFIX stands for ISO (International Standardization Organization) plus FIX (Fixation). ISOFIX car seats make use of two standard attachment points located at the base of the seat, plus an anti-tipping forward device: either a support leg or top tether. From 2006 all new cars are equipped with ISOFIX, and ISOFIX is also fitted in a large number of car brands built prior to 2006.
