Safe and comfortable travel companion. Aton 5 car Seat is equipped with unique safety features. From the height-adjustable headrest with integrated harness guides, which improve the excellent accident safety of the energy absorbing shell in combination with the crash test proven L.S.P. system even further, and new comfort features, e.g. the huge XXL sun canopy, add up to a perfect infant carrier for premature babies and very small newborns. A new function allows an ideal sitting angle and ensures that small babies lie with their head, neck and chest perfectly aligned. The risk of suffocation by the head falling forward is thereby significantly reduced. The infant car seat can be used belted or with one of our optional bases for easy installation.


  • Removable seat insert for a lie-flat position

One of the biggest challenges for safety engineers is the best possible transportation of premature babies and very small newborns, whose neck muscles and reflexes are not yet well enough developed. Unfortunately, this can lead to the baby's head tipping forward while it sleeps, which can lead to serious breathing problems. Along with German doctors and midwives, and taking into account the findings of many tests, a function was developed that enables a near flat lying angle between head, neck and chest. The risk of suffocation is thereby significantly reduced. This is achieved through a removable seat insert, which also offers more space and comfort for bigger children once removed.

Another aspect of the infant carrier‰۪s optimal side-impact protection. The height of the harness adjusts automatically depending on the height of the headrest making the fiddly threading and unthreading of the straps a thing of the past. The Y-harness system has proven to be a very effective and comfortable safety solution particularly for very small babies. The soft seat inlay attached to the headrest can also be used to regulate the height of the baby‰۪s pelvis.

  • Linear Side-impact Protection (L.S.P. System)

The Linear Side-impact Protection (L.S.P. System) absorbs the force of a side-impact collision in combination with the energy absorbing shell. The very first impact of an accident is distributed by the Linear Side-impact Protection System (L.S.P. System) and its extendable protector and absorbed by the flexible material structure of the seat. The flexible material and structure of the infant car seat then absorbs the forces of an impact and channels them away from the baby.
