DIN ISO 27955:2012-01

Vehicles with variable interior space for transporting passengers and, simultaneously, cargo, luggage and recreational equipment have been developed, produced and marketed successfully by nearly all vehicle manufacturers. In order to ensure all-embracing internal safety of such vehicles, it is necessary to effectively reduce the danger to occupants which could arise from the above-mentioned objects during extreme driving manoeuvres and also in accidents. Regulations governing the resistance capabilities of the backrests of the rear seats and for the retaining equipment (partitioning systems) of vehicles of the M1 class, which are intended to protect the occupants from the danger of shifting cargo during a frontal impact, are included in UNECE Regulation No 17, which first came into force in March 1999. In November 2007, uniform conditions have been included in UNECE Regulation No 126 for the approval of retrofit partitioning systems intended to protect the occupants from shifting cargo. Up until now, there has been no complete, internationally recognized and harmonized specification of testing conditions for the resistance capability of front and rear seats in vehicles having a variable interior space concept. DIN 75410-2, published for the first time in July 1992, is used increasingly, even at an international level. In this standard, minimum requirements and tests are defined for devices for the securing of cargo (strength of seat backs, partitioning systems and lashing points) in cars, station wagons and multi-purpose vehicles. This is intended to enable a transport and an operational securing of cargo in vehicles, in order to reduce the risk of injuries to occupants caused. The main idea behind DIN 75410-2 was that lashing points in the luggage compartment, as well as sufficiently resistant seat backs and a partitioning system, are the basic elements for the protection of occupants. All commercially-used cars, station wagons and multi-purpose vehicles within the scope of the accident prevention regulation for vehicles (BGV D29) are required in Germany to be equipped with lashing points and retaining equipment. Furthermore, in certain countries, drivers are obliged by law to properly secure cargo in vehicles in compliance with state of the art. In this context, Working Group ISO/TC 22/SC 12/WG 9 has analysed the requirements of UNECE Regulation No 17, UNECE Regulation No 126 and DIN 75410-2 and has harmonized requirements and test methods in accordance with state of the art. The result is this International Standard ISO 27955, which is a contribution to the international harmonization of requirements to increase the safety of vehicles.
