Cars are designed for adults with a body height of between 150cm and 290cm. Therefore, children must be seated in a safe restraining device. A child seat - properly installed in the car - ensures that the position of the safety belt is better. The child seat protects the child from bone fractures and internal injuries in the case of a crash.
On 1st April 2010, a law came into effect, which demands that children up to the age of 12 years or a body height of up to 150 cm (which is reached first) have to sit in a child seat when in a car. Before this regulation came into effect, children only had to take place in a child seat until the age of 7 years. This age still applies for older vehicles with a lap belt or for school busses. The country-specific regulations (e.g. Germany until 12 years of age, Austria even until 14 years of age) have to be followed if you are travelling within or through these countries with children.
Since 1st April 2010, child car seats have to feature a 44.03- or 44.04-ECE label. All products available on the market today match this norm. Older child seat models, which were built before 1995 and have a 44.01- or 44.02 label are no longer allowed since 1st April 2010.
