ISOFlX - A New Concept of Installing Child Restraints in Cars

Even though child restraint systems (CRS) are very effective there are still serious problems because of non-use or misuse. This is often due to the fact that the installation of the CRS in the cars is difficult, complicated and unstable. A standardised interface between the CRS and the car seat would solve these problems. Within the IS0 Committee ISO/TC22/SC12NVGl this item has been raised and several proposals for an “ISOFIX have been discussed. Apart from the installation aspects, other features e.g. disconnection of passenger airbags can be included in the system. Several concepts called ISOFlX type 1 to 7 with different working names e.g. DELTAFIX, EASY-FIX, MONOFIX and UNlFlX have been evaluated. The handling performance of some of the prototypes have been tested by customer evaluation with very positive results. Crash performance has also been investigated.

The paper will give an update on the latest progress of this development, including a preliminary specification.
