What is the ISOFIX system?
ISOFIX, a system that hooks onto life
The main aim of the ISOFIX system is to avoid errors when installing child restraint systems, which often occurs when they are installed with seat belts and the manufacturers’ instructions are not followed.These are the characteristics of this system:
- There are two anchors or rings attached to the vehicle.These anchors engage with the child car seat by means of rigid bars which are pushed against the rings and locked with a simple click.
- In addition, there is a top anchor point (top tether) or a bottom anchor point (support leg) to prevent the seat from turning or tipping over.
In order to define the characteristics of CRSs we will first have to differentiate between universal and semi-universal seats.
Child car seats belonging to groups 0+ and I with an ISOFIX system are divided into universal and semi-universal, depending on where the third anchor point is located.If it is located at the top of the car seat (top tether), it is a universal seat. If the anchor point extends from the vehicle floor to the base of the seat (support leg), it is considered a semi-universal seat.A universal seat means that the child car seat can be used in any car that has the third top anchorage point while a semi-universal seat can be used in a number of vehicles, but not all of them.In this last case, the child restraint system manual includes a list of vehicles in which the car seat can be used with the ISOFIX system.
