This standard has been prepared by Technical Committee ISO/TC 22 “Road vehicles” (Secretariat: AFNOR, France), Subcom

8、mittee SC 12 “Passive safety crash protection systems”. The ISO Standard is based on the national standard DIN 75410-2:2005-11 which has been submitted to ISO by Germany. The responsible German body involved in its preparation was the Normenausschuss Automobiltechnik (Road Vehicle Engineering Standa

This error has been corrected in both the German and the English versions of DIN ISO 27955 (i.e. in the present standard). The dimension 300 mm is thus shown as beginning from the centre of the head

The following designation is recommended for devices used to secure the cargo as specified in DIN ISO 27955: Securing of cargo DIN ISO 27955 Amendments This standard differs from DIN 75410-2:2005-11 as follows: a) normative r

12、eferences have been updated; b) Clause 3 “Terms and definitions” has been revised and updated; c) requirements in Clause 4 have been rendered more precise and further figures have been included; d) the description of the tests in Clause 5 has been revised and given in more detail and further figures

14、l vehicle manufacturers. In order to ensure all-embracing internal safety of these 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

15、capabilities of the backrests of the rear seats and for the retaining equipment (partitioning systems) of vehicles of the M1class, 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 forc

16、e in March 1999. Since 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 and internationally recognized and harmonized speci

17、fication of testing conditions for the resistance capability of front and rear seats in vehicles having a variable space concept. DIN 75410-2, published in July 1992, is used increasingly, even at international level. In this standard, minimum requirements and tests are defined for devices for the s

18、ecuring 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 b

19、ehind 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. For all commercially-used cars, station wagons and multi-purpose vehicles that are concerned by the ac

20、cident prevention regulation for vehicles (BGV D29), compliance with DIN 75410-2 is mandatory in Germany. 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, ISO/TC 22/SC 12/WG 9 has analysed the req

21、uirements 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, which is a contribution to the international harmonization of requirements to increase the saf

22、ety of vehicles. 40 DIN ISO 27955:2012-01 1 Scope This International Standard applies to devices for the securing of cargo in passenger cars1), station wagons1)and multi-purpose passenger cars1), where the seats directly delimit the loading space. This International Standard defines minimum requirem

23、ents and tests for front and rear seats and partitioning systems, in order to improve the protection of the vehicle occupants against shifting load during a frontal impact. In addition, this International Standard defines minimum requirements and tests for lashing points in the above-mentioned vehic

24、les in order to be able to secure a load (luggage or goods) in a reliable and roadworthy way. For vehicles2)primarily designed for the transportation of cargo and derived from a passenger car1), only the requirements concerning the lashing points of this International Standard apply. Additional requ

25、irements for these vehicles2)and requirements for any other delivery vans are specified in ISO 27956. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the la

40、 27955:2012-01 4.2 Backrests/seats In terms of stability, backrests that are intended to take on the function of delimiting the loading space shall be designed in such a way that they improve the protection of vehicle occupants against shifting load during severe deceleration of the vehicle (see Fig

41、ure 16). During the test in accordance with 5.3, the test blocks shall be retained by the backrest and the locking system of the backrest shall still be engaged. Permanent deformations of the backrest, seat, anchorages, adjustment systems and displacement systems are permissible as long as they do n

42、ot cause injury risks to the occupants. After the test, no sharp or rough edges likely to increase the danger or severity of injuries of the occupants shall be present. NOTE The requirements of this paragraph are deemed to be met for any seat system type approved in accordance with the luggage reten

43、tion requirements of UNECE Regulation No.17. 4.3 Partitioning system Occupants sitting on the rearmost row of seats directly delimiting the loading space should be protected by a partitioning system in order to improve the protection against unsecured load also above the backrests. During the test i

44、n accordance with 5.3, the test blocks shall be retained by the partitioning systems, or the integrated vehicle parts, or both. The partitioning systems, or the integrated vehicle parts, or both, shall remain in position and shall not break away from its attachment points. During the test in accorda

45、nce with 5.3, the front surface of the partitioning systems, or the integrated vehicle parts, or both, if defined as being part of the partitioning system (see Note below), shall not be displaced forward more than 300 mm beyond a transverse plane which touches the rear edge of the seat backs in desi

46、gn position. If, in exceptional cases, the forward movement exceeds 300 mm, the manufacturer shall demonstrate, e.g. with the help of high-speed films, that there is no additional risk for the occupants. In these cases, the following limits may not be exceeded by the forward contour of the partition

47、ing system, or integrated vehicle parts, or both, if they are harder than 50 shore A: up to a transverse plane 100 mm forward of the R point; up to a transverse plane 150 mm forward of the R point for head restraints taking on partially or totally the function of the partitioning system; all measure

48、ment shall be taken in the longitudinal median plane of the corresponding seat or seating position for each seating position constituting the forward boundary of the loading space. Permanent deformations or partial destructions of the partitioning system are permissible as long as no sharp edges, or

49、 separated parts, or both, cause additional injury risks to the occupants. NOTE The vehicle manufacturer can define whether the head restraints or other integrated vehicle parts (e.g. folded backrests) are designed to take on the function of a partitioning system. 80 DIN ISO 27955:2012-01 Dimensions in millimetres Key 1 test block type 1 2 test block type 2 3 partitioning system 4 R-point (seat reference point) Figure 1 Limits of forward displacement for partitioning system 4.4 Lashing points 4.4.1 For vehicles to be equipped with lashing points
