ISOFIX is the international standard for attachment points for child safety seats in passenger cars. The system has other regional names including LATCH ("Lower Anchors and Tethers for Children") in the United States and LUAS ("Lower Universal Anchorage System") or Canfix in Canada.[1] It has also been called the "Universal Child Safety Seat System" or UCSSS.

ISOFIX is International Organization for Standardization standard ISO 13216, which specifies the anchoring system for Group 1 child safety seats. It defines standard attachment points to be manufactured into cars, enabling compliant child safety seats to be quickly and safely secured. ISOFIX is an alternative to securing the seat with seat belts. Seats are secured with a single attachment at the top (top tether) and two attachments at the base of each side of the seat. The full set of anchor points for this system were required in new cars in the United States starting in September 2002.

In the EU the system is known as ISOFIX and covers both Group 0/0+ and Group 1 child safety seats. The mechanism for attaching the seat to the Lower Anchors is quite different from that in the United States. In the EU two "alligator-like" clips connect the seat to the Lower Anchors rather than the open clip style connectors commonly used in the United States.[2] However, some child seat manufacturers are beginning to offer true ISOFIX type attachments in the U.S. In the European standard, there are also various installation categories: "universal", "vehicle-specific" and "semi-universal". The main difference is that "Universal" represents use of a top tether strap with the ISOFIX anchorage, "vehicle-specific" represents the usage of the ISOFIX anchorage without the top tether in specified vehicles only, while "Semi-Universal" represents usage of the ISOFIX anchorage together with a "foot-prop".[3][4]

Isofix is designed to secure a maximum combined weight (comprising both seat and child) of 33kg.[5]

The center-to-center distance between the anchors of ISOFIX (and also LATCH) systems is 280 mm.

For Group 2/3 seats there is a system called ISOFIT which anchors the seat to the vehicle so it cannot slide around when not in use. In the case of Isofit, the child is held into the seat using the vehicle's existing seat belt system, not the safety seat's straps.

On September 19, 2014, the Australian government legalized the use of ISOFIX child seats. Prior to this date, their sale (and use) in Australia was illegal.[6]

The ISOFIX system was developed jointly by child safety seat maker Britax-Römer and automobile maker VW, with the first compatible products released in 1997.[7]

ISO 13216 part 1 (covering lower anchorage points) was published in 1999. Part 2, covering top tether anchorages was published in December 2004.[8][9]

Amendments to include ISOFIX in UN ECE Regulations 14 & 44, which specify uniform provisions for the design of vehicle seat anchorages and child safety seats, came into force in February 2004.[10][11]

Under the current UN/ECE R14, all new vehicles produced since February 2013 are required to have ISOFIX lower anchorages and top tether attachments.

Child safety seat

A child safety seat is a seat designed specifically to protect children from injury or death during vehicle collisions. Most commonly these seats are purchased and installed by car owners, but car manufacturers may integrate them directly into their vehicle's design and generally are required to provide anchors and ensure seat belt compatibility. Many jurisdictions require children defined by age, weight, and/or height to use a government-approved child safety seat when riding in a vehicle. Child safety seats provide passive restraints and must be properly used to be effective. However, research indicates that many child safety restraints are often not installed or used properly. To tackle this negative trend, health officials and child safety experts produce child safety videos to teach proper car seat installation to parents and caregivers.In 1990, the ISO standard ISOFIX was launched in an attempt to provide a standard for fixing car seats into different makes of car. The standard now includes a top tether; the U.S. version of this system is called LATCH. Generally, the ISOFIX system can be used with Groups 0, 0+ and 1.

In 2013, a new car seat regulation was introduced: “i-Size” is the name of a new European safety regulation that affects car seats for children under 15 months of age. It came into effect in July 2013 and provides extra protection in several ways, most notably by providing rearward facing travel for children up to 15 months instead of 9 to 12 months, which the previous EU regulation advised.

Fiat Idea

The Fiat Idea (Type 350) is a five-door, five passenger, front-engine, front-wheel drive, high-roof mini MPV (compact minivan) manufactured and marketed by Fiat (FCA) for model years 2003-2012 — over a single generation with one intermediate facelift.

As FCA's first entry in the mini-MPV market, the Idea's exterior was designed by Fabrizio Giugiaro at Italdesign, its interior was designed by Fiat's Centro Stilo, and its platform is shared with the second-generation Fiat Punto. The monovolume design is noted for its centrally located instrument cluster, high H-point seating, and flexible seating — including reclining, sliding and folding rear seats.

The Idea debuted at the 2003 Geneva International Motor Show, followed a year later by an upscale rebadged variant, the Lancia Musa. Both were manufactured at Fiat's Mirafiori plant and were superseded by the Fiat 500L. Production continued through MY 2016 in Brazil, including the Adventure model, a front-drive variant with increased ground clearance and off-roading pretensions.

The Idea nameplate is an acronym for Intelligent Design Emotive Architecture.

GB standards are the basis for the product testing which products must undergo during the China Compulsory Certificate (CCC) certification. If there is no corresponding GB Standard, CCC is not required.
