The better-designed child car seat.
Concerning the installation of kids car seats, it must be done right. It is about the safety of our children. Anyone who has ever used a kids car seat knows what we are talking about. Conventional kids car seats do not make things easy for parents. Not at all. With their average weight of more than 12 kg and their inflexibility, for long trips the standard ones are rather inconvenient! As both designers and parents, over the years we have observed how kids car seats have become heavier, more complicated and more impractical. At the same time, we know, from personal experience that as parents, we want the absolute opposite. Today it is all about mobility, simplicity and the highest standards in safety. We decided to take on the task! To find the perfect solution. We examined the proven technology critically and had the courage to take new paths. The result is the HY5. Our focus is on today’s parents with children of 0 to 5 years of age.

SAS – Side Air Suspension System

The Side Air Suspension System fills up automatically with the pump in just a few minutes. The intelligent two-color LED warning system indicates ready-to-use and sends signals when the pressure drops below the required system pressure. With the Quick Release button, the seat can be folded together again in a short time. If the pump is not at hand, the standardized valve allows the filling at each petrol station or with all common pumps.

The Reboarder Concept.
The Ultimate in Safety.

The reboarder system – a rear-facing kids car seat – is verifiably the safest solution when it comes to the transport of small children. In the event of an accident in a conventional, forward-facing child car seat, the child’s head is wrenched forward. Depending on the child’s age, weight and size, in a car going only a speed of 50 km/h, upon impact a load of up to 500 kg is put upon the fragile neck of a child. The reboarder system lessens this force significantly. In the event of collision, the rear-facing kids car seat enables the distribution of the load over the entire spine of a child, reducing it over 80%. This difference can save a child’s life!

We’ve passed the tests with flying colours!
An innovative kids car seat has many functions. One function always ranks first: the protection of the child. We expect a lot from the HY5. We must meet the exceptionally high standards of the strict test criteria of the European ADAC and the “Stiftung Warentest”. The HY5 was put through elaborate multi-tiered testing procedures by the world’s leading experts at product testing facilities. Professional crash tests were simulated using extreme conditions and the same loads were utilised on our car seats as those which occur in real life car accidents. Using sensors and highspeed cameras, the safety performance of the HY5 was measured objectively.

In addition, the HY5 was tested for its functionality regarding temperature and air pressure fluctuations. And we assessed the response behaviour to impact to foreign objects. The tests endorse our most important ambitions. The patented technology of the HY5 is unique, extremely stable yet at the same time pliable and load absorbant. The HY5 functions like a protective airbag and additionally wins you over due to its extreme lightness and minimal use of materials. The HY5 provides the perfect protection for your child.
