Correct installation indicator

The presence in the design of the child restraint system of special indicators of correct installation. They help ensure that the child car seat is installed correctly and follows all prescribed safety guidelines. Most often, such indicators are represented by special marks that change color or position when the car seat is installed correctly. Such indicators are placed on Isofix system locks, seat belts for fastening a child, etc. And some models for the youngest passengers have built-in levels or angle indicators that help set the seat in the correct position, facing the rear of the vehicle.

Adjustments

Backrest tilt adjustment. The backrest tilt can be adjusted. This point is different for various weight groups. In groups 0+ and 1 not the backrest, but the whole seat tilts against the fixed base, and in groups 2 and 2/3 only the backrest tilts. The possibility of adjusting the backrest tilt is important if the child is in the car for a long time – by tilting the backrest you can let the child sleep or rest.

Headrest height adjustment. According to safety requirements, the child's head should not be more than one third above the headrest, so it is necessary to adjust the headrest as the child grows.

Harness height adjustment. The ability to adjust the height of car seat harnesses — such a need arises as the child grows.

Backrest width adjustment. The ability to adjust the width of the backrest allows you to optimally adjust the car seat not only for constantly changing height, but also for the child's complexion.

Horizontal position of a backrest. The backrest of the car seat is horizontal. The horizontal position is optimal for babies under the age of six months, since it avoids unnecessary stress on the spine, therefore group 0 car seats usually have this function.

Removable backrest. It is possible to comp...letely remove the backrest of the car seat. This function expands the possibilities of the seat: it can be used both for its intended purpose, with a backrest, and as a booster (for more information on boosters, refer to "Weight group 3").

Swivel system. The seat swivels relative to a fixed base. This makes it easier to drop off and pick up the child: during these operations, the seat can be turned to face the car door, and when driving, it can be positioned in or against the direction of travel.

Additional side protection

The car seat has structural elements that further protect the child from side impacts. At least such elements include sidewalls for head protection made of impact-absorbing material such as polyurethane foam; torso protection may also be provided. If you are looking for a car seat with the maximum level of protection, you should choose from models with additional side protection.
