✅ From 15 months to 12 years old
✅ From 76cm to 150cm
✅ Isofix Installation
✅ Approval: R129 (i-Size)
The Advansafix PRO car seat is designed to grow with your child, suitable from 15 months old and 76 cm tall up to 150 cm (approx. 12 years), approved under the R129 (i-Size) safety standard. It always faces forward, and the transition from the five-point harness (76-105 cm or 22 kg) to the three-point seat belt with SecureGuard (100-150 cm) is quick and easy with the FLIP&GROW system.
76-105 cm or 22 kg: 5-point harness
From 76 cm and 15 months up to 105 cm in height or 22 kg in weight (whichever comes first), the child is secured in the car seat with a five-point harness, which distributes impact forces across five points: two at the shoulders, two at the hips, and one at the buckle located between the legs. The harness pads reduce the child's movement in the event of a collision, as well as providing greater comfort for the harness. In this stage, the car seat is installed using Isofix and a top tether.
100-150 cm: seat belt with SecureGuard
From 100 cm in height (and no later than 105 cm or 22 kg), the child is secured directly with the car's three-point seat belt, in combination with SecureGuard. This piece adds a fourth anchor point to the belt to keep the lap section in the correct position over the pelvic area, preventing it from dangerously riding up to the abdomen. It helps reduce forces on the abdomen by up to 35% in a frontal impact. In this stage, the car seat is installed using Isofix.
When it's time to switch from the harness to the seat belt, the transition is much easier thanks to the FLIP&GROW function. Simply press a button to unlock the headrest and adjust it to the required height, then store the harness (without removing the chest pads) in the back of the backrest, behind the cover, so it won't get lost. Next, move the FLIP&GROW adjustment plate, rotate it to position the SecureGuard over the car seat, and the transition is complete.
