Ta le 1: references, names, materials and
princip l d imensions of the components of the
manikin;
Ta le 2: mas of head , neck, tor o, thig hs an
lower leg
A.2 Com ponents of the m anikin
A.2.1 Lower leg str uctur e ( se Fig ure 3 and
Fig ure 4) The lower leg structure consists of thre
components:
a sole plate( 30);
a shin tube( 29);
a k e tube( 26)
The k e tube has two lug s which l mit the
mov ement of the lower leg in relation to the thig h
The lower leg can rotate rearwards a out1 0° f om
the straig ht position
A.2.2 Thigh str uctur e ( se Fig ure 3 and Fig ure 4)
The thig h structure consists of thre components:
a k e tube( 22);
a thig h b r( 21);
a hip tube( 20)
Mov ement of the k e is l mited b two cut-outs in
the k e tube( 22) which eng ag e with the lug sof the
leg
A.2.3 Tor so str uctur e ( se Fig ure 1 and Fig ure 2)
The tor o structure consists of the folowing
chain at achments( 3 and, p rtly , 7 and8)
A.2.4 Ne k ( se Figure 1 and Figure 2) The neck
consists of six poly urethane d is s ( 9) The deg re of
stifnes of the neck can be a justed b means of a
chain tensioner
A.2.5 Hea d ( se Fig ure 1 and Figure 2) The
hea ( 15) is hol ow; the poly urethane is reinfor ed
b ste l b nd s( 17) The chain tensioner which
ena les the neck to be a justed consists of a
poly amid e block( 10), a tubular sp cer( 11) and a
tensioning component( 12 and13) The hea can
rotate at the joint betwe n the fir t and second
cerv ical v ertebrae ( the atlas-a is joint), which
consists ofan a juster as embly( 14 and18), a
sp cer( 16) and a poly amide block( 10)
A.2.6 Kne joint ( se Fig ure 4) The lower leg and
thig hs are con ected b a tube( 27) and a
tensioner( 28)
A.2.7 Hip joint ( se Fig ure 4) The thig hs an tor o
are con ected b a tube( 23), f iction plates( 24) and
a tensioner( 25)

A.3 Cor e tion of the m as
In order to cal brate the manikin to certain v alues
and its total mas , the mas distribution shal be
a justed b means of six cor ection weig hts of1kg
each which can be fit ed to the hip joint and six
other poly urethane weig hts of1kg each which can
be fit ed to the b ck of the tor o
A.4 Cushion
A cushion shal be positioned betwe n the chest of
the manikin and the ov eral This cushion shal be
ma e of poly ethy lene foam comply ing with the
folowing specification:
hard nes :7shore A to10shore A;
thick es :25±5mm
It shal be replacea le
A.5 Adjustm ent of the joints
A.5.1 Gener a l In ord er to achiev e reprod ucible
results, it is neces ary to specify an control the
f iction at each joint
Trang 18A.5.2 Kne joint Tig hten the k e joint.
Set the thig hs and lower leg v ertical
Rotate the lower leg throug h3 °
Grad ual y slacken the tensioner u ti the lower leg
starts to fal u d er its own weig ht
Lock the tensioner in this position
A.5.3 Hip joints Inc ease the rig id ity of the hip
joints for the purposes of ad justment
Place the thig hs in a horiz ntal position and the
tor o in a v ertical position
Rotate the tor o forwards u ti it forms an angle
of6 ° with the thig hs
Gra ual y slacken the tensioner u ti the tor o
starts to fal u der its own weig ht
Lock the tensioner in this position
A.5.4 A tla s-a xis joint Ad just the atlas-a is joint so
that it just resists its own weig ht in the fore and aft
d irections
A.5.5 Ne k Adjust the neck b means ofthe chain
tensioner( 13) so that when ad justed, the up er end
of the tensioner is displaced betwe n4 mm
and6 mm when subjected to a horiz ntal load
