1、AUTOMOTIVE SAFETY The increasing importance of safety perform- ance in all aspects of motor vehicle design, development, manufacturing and marketing, makes itnecessary for professionals working in these areas to develop an understanding and awareness of safety considerations to effec- tively handle

2、future developments in this area. Automotive Safety: Anatomy, Injury, Testing and Regulation begins with a clear, concise introduction to the terminology and concepts relating to human anatomy and injury. This comprehensive bookthenfocuses on the types of injuries that occur by body region and the m

3、echanisms thought to cause them. Selected anatomical, physiological and clinical concepts are included to support the injury material presented. Injury scaling is also discussed, reviewing techniques such as the Abbreviated Injury Scale (AIS), GlasgowComa Scale (GCS), and Harm and Impairment. This i

4、nformative publication concludeswith a discussion on the regulatoryframeworkandbiomechanical basis of Federal Motor Vehicle Safety Standard (FMVSS) 208 and the New Car Assessment Program (NCAP). Organized into four information-packed chapters, contents of this valuable publication include: Terminolo

5、gy; Anatomy and Injury; Injury Scaling; Regulation and Testing. Appendices include various safety laws and regulatory-related documents which are referred to in the text. In addition, R-103 includes an extensive reference section and is packed with illustrations and diagrams. Automotive Safety: Anat

6、omy, Injury, Testing andRegulation is an essential reference for all automotive safety professionals-either tech- nical ormanagerial, as well as anyonewanting a better understanding of this fascinating area of study. ,5 f eThe EngineeringSociety _ ForAdvancing Moblilty W-LandSea AirandSpace IN TERNA

Iknow there were many people helping “behind the scenes“ and I hope they will know this thank you is for them as well. itro uc ion Thisbook is theoutgrowth ofanumberoflectures Ihavepresented during the last five years.Aswas thecase with those lectures, thebookdiscusses “spe

12、cifics“and also seeks to provide background material and concepts which will be most useful over a long period oftime, both in theirown rightand as afoundation foradditional study especially to help grasp future developments. The text of this book is divided into four chapters: Terminology, Anatomy

13、and Injury, Injury Scaling,andRegulationsandTesting. Chapter 1,Terminology,provides a non-technical introduction to some of the terminology and concepts relating to the bodys structure and function, which are used in the other chapters. Chapter 2, Anatomy and Injury, provides a discussion, by body r

14、egion, of the types of injuries which occur and the mechanisms thought to cause them. Most of the technical terms are defined as they are introduced into the discussion, and so this chapter should be “readable“ without a clinical or injury biomechanics background. It does, however, discusssomefairly

15、advancedconcepts,andsoshouldbeofinteresttothosewith strong clinicaland/orbiomechanicsbackgrounds as well.Chapter3,Injury Scaling,discusses various techniques for assigning a numerical assessment to various injuries. The numbermay represent a ranking, such as is the case for the Abbreviated Injury Sc

Chapter 4, Regulation and Testing,discussestheregulatoryframeworkandbiomechanical

17、basisofFederalMotor Vehicle Safety Standard (FMVSS) 208 (“Occupant Crash Protection“) and theNew Car Assessment Program (NCAP). The discussion includes the tests themselves, existing and proposed test criteria, and the test dummies. Finally, the Appendices provide copies of various safety laws and r

Many of the terms and concepts introduced in this chapter will be discussed in Chapter 2,whichcovers injury toeachbodyregion in detail.Thischapter ends with a brief annotated bibliography for th

It is anticipated that people with a wide variety of back- grounds will beusing thisbookandthatsomeofthematerial will be much more familiar to some readers than to others. As a general guideline, it is suggested that a reader who is already qui

25、te familiar with such terms as “anterior superior iliac spine,“. “mid-sagittal“ and “eversion,“ might wish to glance at this chapter, but probably need not read it in detail.

27、nd, as such, is frequently concerned with describing the shape and location of various parts of the body. One way of specifying location is to divide the body into regions. For ex- ample, the deltoid or shoulder region, the hip, the scapular or shoulder blade region, the calf, the shin, the sole of

28、the foot (plantar region) and so on (Figures 1.1 and 1.2). Anotherfrequently usedmethod ofdescribing location is to specify relative location, i.e., superior(toward the head), inferior (away from the head), anterior (towards the front), posterior (towards the rear) (Figure 1.3), medial (toward the c

29、enter), and lateral (away from the center). These pairs ofterms may be considered as describing a set ofaxes.

It is a very straightforward ste

32、p to extend the Cartesian coordinate system (Figure 1.4a) to the anatomical coordinate system (Figure 1.4b). The positive Y-axis corresponds to the superior direction, and the positive Z-axis corresponds to the anterior direction. The X-axis corresponds to the lateral-medial axis. For the purpose of

33、explanation, the positive X-axis will be assumed to correspond to the lateral direction. (This will be explained more fully later.) This is shown in Figure 1.4b. The X, Y and Z, or lateral-medial, superior-inferior, and anterior-posterior axes, respectively, alsomay be defined as the ANATOMICAL LAT.

In fact, in some instances, the anatomical planes aremore frequently referred to than the anatomical axes. Figu

35、re 1.5b indicates the three planes: the sagittalplanelabeledwithan S,thecoronalplanelabeledwith aC, and the transverse plane labeled with a T. These planes are superimposed over a human figure in Figure 1.5c. It should be noted (Figure 1.5c), that the particular sagittal plane which goes through the

36、 center of the body (dividing it into right and left halves) is referred to as the mid-sagittal plane or median plane. (Anyplaneparallel to this,butnotin thecenterofthebody,would be a sagittal plane.) The plane which goes “through the ears“ so as to divide the body into afrontandrearhalf is referred

37、 to as the coronal plane. The third plane illustrated in Figure 1.5c is the plane bisecting the body into upper and lower halves. This is called the transverse or horizontal plane. It is clear that for the body position shown in Figure 1.5, the calf is below the knee. Therefore, the calf can be said

38、 to be “inferior to the knee,“ or the calfregion can be said tobe inferior to the knee region. Similarly, it can be said that “the knee is superior to the calf.“ Within the coronal plane, a location can be specified which is either toward the center line of the body (referred to as “medial“) orawayf

39、rom the center line ofthebody (referred to as “lateral“). For example, the clavicle is a bone which is oriented approximately in the medial-lateral direction, and, therefore, reference can bemade to the “lateral“ part ofthe bone, which is the partcloser to the shoulder, and the “medial“ partofthe bo

40、ne, which is the part closer to the sternum (Figure 1.6). Otherfrequently used terms are internal (deep) and external (superficial) andproximal (near)and distal (far). Internal ordeep refers to locations relatively deep within the body whereas 2 TERMINOLOGYCHAPTER 1 1. CARTESIAN V FXZ (a) 111. ANATO

Thus,w

Proximal describes thatwhich is closer, eitherto themidline of the body or to some other reference, and distal, the opposite, refers to a location which is further away from t

43、he median or some other reference. Proximal and distal are most frequently usedwhendescribing locationonalimb, inwhichcasetheyrefer, respectively, to near or far with regard to the point ofattachment ofthe limb to the torso. Thus, the knee is proximal to the ankle, but the knee is distal to the thig

44、h. Frequently, fractures along the shaft ofa long bone such as the femur, tibia and fibula (Figure 1.6) are described, in part, by theirlocation alongthe length ofthebone.Thedesignation refers to the standard anatomical position and is basedon conceptually dividing the bones length into thirds. The

45、third closest to the torso isdescribed asthe“proximal“third(abbreviated “P/3“),the middle third isdescribed asjustthat (abbreviated“M/3“),andthe third furthest from the torso is described as the “distal“ third (abbreviated “D/3“). Thus, a fracture oftheproximal third ofthe femur would indicate that

46、the fracture is located in the superior (cephalic)regionofthethigh(nearthehip),ratherthanbeingnear the knee, or in the middle ofthe thigh. (This is discussed inmore detail in the section on the pelvis in Chapter 2.) It isimportant tonote thatanatomical terminology isalways used with respect to a ref

47、erence position for the body, the “anatomical position“ (Figures 1.1 and 1.6). Basically, it is a standing erect position facing forward, palms forward. It is X X SJ-ELVI FEMUR PATELLA LEG J?AXLA Figure 1.6 - The Skeleton - - Front View important to note, in particular, with regard to the descriptio

48、n of injury location, thatregardlessofthepositionandarrangementof the particular injured person being described, the anatomical terminology is with regard to the anatomical position. Thus, the wrist isalways distal to theelbow, regardless ofhow a particular upper limbmay be positioned, e.g., even if

49、the elbow is bent, so that inaparticularinstance, thewrist isclosertothetorsothanthe elbow. Itisfrequentlyconvenienttodiscussthebodywithreference to rather obvious subdivisions, namely the head, neck, upper extremities, lower extremities and torso (Figure 1. 1). The trunk or torso may be further subdivided into an upper region, the thorax, and a lower region, the abdomen. (Note: the term stomach, which is sometimes informally used to denote the abdomen, shouldnotbeused inthatcontext. Rather, thestomach refers to a particular organ within
