of the centre of gravity;

                  location of points at which displacement shall be measured; and

                  shoulder height.

         Table 1 References, names, materials and principal dimensions of  components of the manikin; and

         Table 2 Masses of head, neck, torso, thighs and lower leg.

         1.2. Description of the manikin

         1.2.1. Structure of the lower leg (see Figures 3 and 4)

         The structure of the lower leg consists of three components:

            a sole plate (30);

            a shin tube (29); and

            a knee tube (26).

         The knee tube has two lugs which limit the movement of the lower leg in relation to the thigh.

         The lower leg can be rotated rearwards 120° from the straight position.

         1.2.2. Structure of the thigh (see Figures 3 and 4)

          The structure of the thigh consists of three components:

            knee tube (22);

            a thigh bar (21); and

            a hip tube (20).

         Movement of the knee is limited by two cut‑outs in the knee tube (22) which engage with the lugs of the lower leg.

         1.2.3. Structure of the torso (see Figures 1 and 2)

          The structure of the torso consists of:

            a hip tube (2);

            a roller chain (4);

            ribs (6) and (7);

            a sternum (8); and

            chain attachments (3) and at parts (7) and (8).

         1.2.4. Neck (see Figures 1 and 2)

         The neck consists of seven polyurethane discs (9). The stiffness of the neck can be adjusted by means of a chain tensioner.

         1.2.5. Head (see Figures 1 and 2)

         The head (15) itself is hollow; the polyurethane form is reinforced by steel plate (17). The chain tensioner by which the neck can be adjusted consists of a polyamide block (10), a tubular spacer (11), and tensioning members (12)
         and (13). The head can be turned about the Atlas‑Axis joint, which consists of the adjuster assembly (14) and (18), the spacer (16), and polyamide block (10).

         1.2.6. Knee joint (see Figure 4)

         The lower leg and thighs are connected by a tube (27) and a tensioner (28).

         1.2.7. Hip joint (see Figure 4)

         The thighs and torso are connected by a tube (23), friction plates (24), and tensioner assembly (25).

         1.2.8. Polyurethane

         Type: PU 123 CH Compound

         Hardness: 50‑60 Shore A

         1.2.9. Overalls

         The manikin is covered by a special overall (see table 1).

         2. Correction devices

         2.1. General

         In order to calibrate the manikin to certain values and its total mass, the mass distribution are adjusted by the use of six correction steel masses of 1 kg each, which can be mounted at the hip joint. Six polyurethane weights each of 1 kg mass can be mounted in the back of the torso.

         3. Cushion

         A cushion must be positioned between the chest of the
