| Kidfix II XP | XP-Pad + SICT | Isofix + belt | 7.4 kg |
| Kidfix III M | SecureGuard + SICT | Isofix + belt | 7.2 kg |
| Advansafix IV M | V-back | Isofix + Top Tether | 8.1 kg |

This lining absorbs up to 30% of the impact energy, distributing the load over a larger area of the body and reducing the risk of chest and neck injuries. For parents who travel frequently along the track, this option is not just an addition, but a necessity.
Series versions M Kidfix III M received an improved system SecureGuard, which forcibly lowers the diagonal part of the seat belt into the safe zone, excluding its hit on the neck of the child. This is especially true for thin children or cars with high seating, where the geometry of the belts is often disturbed.
Instructions for proper installation in the car
The installation process begins with checking your vehicle’s compatibility with the system. Isofix. Find metal brackets in the gap between the back and the seat cushion. Push the guide seats to the click, making sure the indicators are green, indicating correct fixation.

The diagonal strap should pass through the shoulder without touching the neck, and the waist strap should lie low on the pelvic bones, passing through special "horns" or guides to the seat of the chair. If the belt is dangling, use a tensioner or check if it is twisted.
Pay special attention to the back angle. In models Britax Römer There is an adjustment of the slope, which allows you to compensate for the lifting of the car seat.

It should be raised so that the upper edge of the sidewalls is at the level of the child's shoulders, but does not rest on them. The height adjustment is made by simply pulling the head restraint upwards until the characteristic click of the locking mechanism.
Secrets of SecureGuard configuration

The use of aggressive bleachers or conditioners for underwear is prohibited, as they can destroy the flame retardant impregnation of the fabric and reduce its strength. Drying elements must be in a straightened form, away from direct sunlight and heating devices.
Use a soft brush and soap solution to remove complex stains, avoiding excessive moisturizing of the foam. Complete drying of the cover before assembly is mandatory in order to avoid the appearance of mold.
Plastic elements of the body wipe with a wet napkin without alcohol. Aggressive chemistry can make plastics brittle over time, which is dangerous in the event of an accident. Regularly check the mobility of all mechanisms and lubricate the hinges, if necessary, with special means recommended by the manufacturer.
Frequent problems and ways to fix them
One common problem is the “false click” of Isofix locks when the indicator lights up green, but no actual brace capture has occurred. This often happens when there are foreign objects in the mounting zone or when the guides are displaced. Visually check the grip by looking under the chair with a flashlight.
Another problem is the child slipping under the belt (“diving”). This happens if the seat belt belt belt belt is placed too high on the stomach. The solution lies in the correct configuration of the system SecureGuard or using a model with more pronounced seats that hold the pelvis.
- 🔍 Problem: It is difficult to fasten the belt lock. Solution: Check if the cover has fallen into the lock mechanism.
- 🔍 Problem: Screaming plastic. Solution: Lubricate rubbing surfaces with silicone lubrication.
- 🔍 Problem: The rickety chair. Solution: Pull Isofix mounts and check the angle of inclination.
⚠️ If after the accident, even the lightest, there were hidden microcracks in the structure of the plastic on the chair, its further use is impossible. The material loses its cushioning properties and must be disposed of.
