THE ISOFIX ANCHOR
The ISOFIX system refers to the anchor that fixes the child seat to the vehicle. Instead of using the car seatbelt to fix the seat in, the ISOFIX system uses three anchoring points, two in the base of the child seat that lock into two rigid anchors situated between the seat back and the seat of the car and a third situated either in the upper part or the lower which stops the seat from rotating or overturning.
TYPES OF ISOFIX SEATS
ISOFIX seats are suitable for children from group 0,0+ and I. Also certain seats from groups II/III are fitted with this system although it is sometimes called Quickfix. The seat in group 0+ and I using ISOFIX are divided into two groups, Universal and Semi-universal, depending on where the third anchor is situated. If it is on the upper part or Top Tether it is known as Universal and if the anchor point is from the floor then it is known as Semi-universal. Universal means that the seat can be used in any car with an upper anchor, while the Semi-universal can be used in many vehicles but not all. In the instructions for each seat you will find information on which vehicles you can use it in.
ADVANTAGES OF THE ISOFIX SYSTEM
First of all, thanks to the anchors that fix the child seat to the car seat, this is a much stronger system. Also, since it doesn’t use the seatbelt to fix the child seat into position in the vehicle it is much more difficult to make mistakes. In a head-on collision, the ISOFIX system reduces the movement of the head, reducing whiplash and spinal injury. In a lateral impact the chances of the seat being displaced inside the vehicle is much less since is has greater stability.
This restraining system has been obligatory in all new vehicles since June 2005, apart from if you have an older car, (you must install the child seat using the seatbelt) so we are able to take advantage of the ISOFIX system, reducing by another 22% the serious injuries to children in an accident (all seats already offer a reduction in this risk by 50 to 90%).
