DESCRIPTION OF MANIKIN

          1. Specifications of the manikin

          1.1. General

          The main characteristics of the manikin are illustrated in the following figures and tables:

Figure 1 Side view of head, neck and torso;

Figure 2 Front view of head, neck and torso;

Figure 3 Side view of hip, thighs and lower leg;

Figure 4 Front view of hip, thighs and lower leg;

                    location 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
