The international standard for attachment points for child car seats as well as defining that standard attachment points be manufactured into cars, enabling easily and safely compliant seats.

An alternative to securing a child car seat with seat belts, usually indicated on a label near the ISOFIX bracket. Compliant car seats will have ISOFIX clamps that will attach to the ISOFIX in the vehicle. Clamps are usually at the bottom of the seat or on the base of the baby seat. The ECE label will tell you that it is a Semi-Universal seat.

ISOFIX only provides 2 points of contact and a third point is required for a safe installation. The clamp on the bracket becomes a hinge during a crash and that is why the third point of contact is required.

The ISOFIX must be used in conjunction with a back tether strap, a load leg or a shield that braces against the backrest of your vehicle. Either one of these will diminish rebound during a crash and thus protect your child’s head and neck. In a crash, there is a benefit to a seat belt installation due to the slight movement of the seat. The slight movement absorbs crash force
and prevents it from feeding through to your child. ISOFIX is considered safer than a seatbelt installation due to its ease of use, thereby eliminating incorrect installation issues.

Check your car seat manual to confirm that your installation is correct. Make sure you double check the installation for firmness before each trip.
