    6、(E) Foreword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which

    7、 a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all mat

    8、ters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circu

    9、lated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. In exceptional circumstances, when a technical committee has collected data of a different kind from that which is normally published as an Internat

    10、ional Standard (“state of the art”, for example), it may decide by a simple majority vote of its participating members to publish a Technical Report. A Technical Report is entirely informative in nature and does not have to be reviewed until the data it provides are considered to be no longer valid

    11、or useful. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO/TR 14933 was prepared by Technical Committee ISO/TC 22, Road vehicles, Subcommittee SC

This second edition cancels and replaces the first edition (ISO/TR 14933:2001), which has been technically revised.iv ISO 2012 All rights reserved ISO/TR 14933:2012(E) Introduction Side air bags (SAB) are inflatable devices intended to help reduce the risk of injury to t

    13、he head and/or the chest and/or the pelvis of vehicle occupants adjacent to the impacted side of the vehicle. Side impact accident data indicate that the vehicle side is most likely to come into contact with a passenger car, a truck or a fixed object, such as a pole or tree 1) . Accident data also i

    14、ndicate that serious-to-fatal injuries in side impact are most likely to occur to the head, neck, chest, abdomen, pelvis and extremities. During its inflation process in an accident, an air bag generates a considerable amount of kinetic energy and, as a result, substantial forces can be developed be

    15、tween the deploying air bag and the nearby occupant. A considerable but unknown portion of the occupant population does not drive/ride in exactly the vehicle design position, but lean/rest in various ways against the armrest, door, glazing or other side panel of the vehicle, where air bag reaction f

    16、orces may be even greater. These test procedures were developed to help improve the understanding of such interactions and to help aid in the assessment of future air bag designs. This Technical Report describes the more common interactions, recognizing that the range of possible interactions is ess

    17、entially limitless. References 1to 5provide some background on human impact tolerance and criteria, while references 6and 7d e s c r i b e s c a l i n g t e c h n i q u e s f o r d i f f e r e n t s i z e o c c u p a n t s a n d r e f e r e n c e s 8to 10offer interpretations of dummy responses rela

Th

    20、e in-position test procedures are referred to in other ISO international standards, such as, full-vehicle pole crash tests (ISO 15829) and instrumented arm evaluations (ISO 15827). Out-of-position vehicle occupant test procedures are described in this Technical Report. This Technical Report describe

    21、s dummies, procedures, instrumentation and test configurations that can be used for investigating the interactions that occur between a deploying side air bag and a vehicle occupant in front and rear seats. Air bags may deploy from the door or side trim panel, the armrest, the seat back or cushion,

    22、the roof support pillars, and the roof rail area. Occupants can range in size from young children through very large adults. These test procedures are sufficiently broad to cover these areas. Static tests are used for these evaluations, since external forces do not accelerate the vehicle buck. 2 Nor

These dummies are referenced in ISO/TR 12349 (all parts). The dummys head skin should be cleaned with alcohol and dusted with baby powder to achieve acceptabl

    33、e frictional characteristics. 4.2.2 SID-IIs The SID-IIs represents a 50th percentile 12 to 13 year old adolescent or small adult generic dummy designed to indicate injury potential to the head, neck, shoulder, arm, chest, abdomen, lumbar spine, pelvis, thighs and legs as described in Par t 572. The

    34、SID-IIs has been fully evaluated and has been adopted 2 ISO 2012 All rights reserved ISO/TR 14933:2012(E) into ISO/TR 12349 for use. See references 11to 13for instrumentation details. It was specifically designed to help evaluate the injury potential of side air bags 11to. 13 5 Instrumentation 5.1 G

    35、eneral Measurements, possibly applicable to air bag testing, that can be made using the approved anthropomorphic test device for each age group are contained in ISO/TR 12349. All measurements should be recorded and filtered according to the latest version of ISO 6487 and SAE J211 for body regions. T

    36、hese measurements should be continuous functions of time, so that other quantities referred to in the references may be derived. Caution must be exercised with dummy compression measurements. In some of these tests, the rate of loading may be high enough to cause discontinuities in the compression d

    37、ata of the SID-IIs. Monitor the air bag deployment and dummy interactions by high-speed cameras (or equivalent video equipment) operating at a minimum speed of 1000 frames per second (3000 fps is recommended). The cameras should be positioned so that the field-of-view encompasses the test setup and

    38、includes the anticipated movement of the dummy during the test. 5.2 Dummy test temperature The test dummy temperature should be within a temperature range of 20,6 C to 22,2 C at a relative humidity to 10 % to 70 % after a soak period of at least 4 h prior to its application in a test, or that specif

    39、ied for the dummy by the manufacturer. 5.3 Electrical grounding The test dummy, vehicle and all related instrumentation must be grounded to the data collection system. The test dummy shall be grounded with cables attached to the dummys head, thorax and pelvis, which shall be connected to earth groun

    40、d during all testing. Between tests, spray the dummy with an anti- static spray. These are both very important due to the high likelihood for electrostatic discharges as a result of the inflating air bag. 6 Air bag location/impacting object/other test matrix The vehicle-to-fixed pole crash test proc

    41、edure was selected in Table 1 instead of a dynamic side impact crash test or high-hooded vehicle simulation crash test. The rationale is that a pole crash test is the most severe and produces the highest dummy interaction responses. Additionally, a pole test presents the greatest challenge for desig

    42、ning the side air bag sensor system. The child/adult out-of-position and instrumented arm interaction tests are shown in Tables 2 and 3 for front and rear seating positions.
