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 ISO Committee ISO/TC22/SC12/WG1 this item has been raised and several proposals for an "ISOFIX" have been discussed. Apart from the installation aspects, other features such as disconnection of passenger airbags can be included in the system. Several concepts called ISOFIX 1 to 7 with different working names such as DELTAFIX, EASY-FIX, MONOFIX and UNIFIX have been evaluated. This paper gives an update on the latest progress of this development, including a preliminary specification.
