Extended rear-facing: describes car seats which allow a child to travel rearward for longer. This means that Some extended rear-facing seats are designed for children up to 18kgs
i-size: is the latest european regulation (R129) with higher standards for safety testing and ease of use. The key changes include: advanced side impact testing, mandatory rear-facing until child is 15 months, height and weight based (previous regulation emphasised only weight) and ISOFIX only (prevents misuse).
ISOFIX: is an international standardised system for fitting child car seats or car seat bases. The way ISOFIX works is by using special attachment points built into the car seat or a car seat base which are then pushed into the right ISOFIX points in the car. Essentially, the car seat’s ISOFIX attachments simply ‘click’ into place and the car seat becomes part of the car’s metal structure. ISOFIX points in the car are metal mounts or hooks which are located in the seats at the back.
Although most new cars in Europe are fitted with ISOFIX, always double check in the car manual. Car seats with ISOFIX are safer than belted car seats because it’s easier to install a car seat with ISOFIX so the the risk of incorrect installation is minimised.
Side impact protection: the ability of a car seat to protect the child in the event of a crash to the side of the car. All car seats, with the exception of backless boosters, provide some side impact protection. Advanced side impact protection car seats provide additional protection in a side crash. New EU regulations (R129) require new i-size car seats to be tested in a simulated side impact crash, making these seats safer.
