How have vehicles adapted to the i-Size standard?

How are vehicles adapting to the i-Size standard?

21/10/2016

The i-Size standard is something new to many people, but in fact it was approved over two years ago and is currently in force alongside the ECE R44 standard. The main obstacle to the i-Size standard was the very limited variety of products on the market, but today more and more child seat manufacturers are launching models in line with this standard.

Older vehicles are not obliged to adapt to the i-Size standard; however, new ones are expected to adapt to it progressively. The new child restraint systems can be anchored to the ISOFIX fittings in some models and the fundamental difference compared to other systems is that they are not compatible with the car's seat belts. This has been done to avoid the possibility of human error when fitting them, which very often happens when using seat belts.

Using the ISOFIX system, the child restraint system fits into place instantly and there is only one possible position in each direction, thus maximizing children's protection once seated and with the harnesses in place.

¿Cómo se han adaptado los vehículos a la norma i-Size?

As in the case of child restraint systems covered by the ECE R44 standard, the task of parents before they buy an i-Size seat is to check that it fits properly in the section of seat designated for that purpose (the back seat, as explained in the article “How the new standard affects the positioning of your child seat”. What you should bear in mind is that not all cars are suitable for i-Size seats.

An i-Size CRS must be fitted into an i-Size car seat

It might seem obvious, but i-Size child restraint systems are designed to be used in car seats that comply with the i-Size standard. This has a series of implications:

  • Not all cars can accommodate an i-Size seat. A CRS of this type cannot be used in any car that does not have the ISOFIX system.
  • Although the ISOFIX fittings are suitable for i-Size seats, not every car model with an ISOFIX system is able to accommodate a seat of this type.

Some new models (after 2013) are already equipped to accommodate this type of child restraint system. The best way of finding out whether a particular model is compatible with the i-Size seat is to look for the label stating this compatibility. The car's manual has to state which seats are compatible with the i-Size system, which are normally the back seats.

When choosing an i-Size child seat, you follow the same procedure as any other CRS. Firstly, select the right seat for the child in question (according to their height, not their weight), and bear in mind that the seat must be accommodated in the car's i-Size seats, so before you do anything else make sure you know which cars these seats can be used in.

This information should be given in the vehicle's owner's manual. Failing this, the manufacturers of child restraint systems can also give you an up-to-date list of the vehicles that are i-Size compliant. You should bear in mind that not every seat position can be designated as "i-Size".
