Neck Sample Clauses

Neck. The neck is flexible and allows shear and bending in all directions. The segmented design allows a realistic rotational behaviour. The neck is equipped with low stretch neck-cord in order to prevent excessive elongation. The neck-cord is also designed to act as a safety cord in case of rubber failure. A six channel load cell can be mounted at the neck-head and neck-torso interface. The Q0, Q1 and Q1.5 cannot accommodate the load cell between neck and torso.

Neck. 5.6.1. The head-neck interface of the neck is mounted to a special certification head-form with a mass of 3.9 ± 0.05 kg (see Figure 6), with the help of a 12 mm thick interface plate with a mass of 0.205 ± 0.05

Neck. 2.3.1. The neck is shown as part No. 2 in Figure 1 of this annex. 2.3.2. The neck consists of a head-neck interface piece, a neck-thorax interface piece and a central section that links the two interfaces to one another. 2.3.3. The head-neck interface piece (part No. 2a) and the neck-thorax interface piece (part No. 2c) both consist of two aluminium disks linked together by means of a half spherical screw and eight rubber buffers. 2.3.4. The cylindrical central section (part No. 2b) is made of rubber. At both sides an aluminium disk of the interface pieces is moulded in the rubber part. 2.3.5. The neck is mounted on the neck-bracket, shown as part No. 2d in Figure 1 of this annex. This bracket can optionally be replaced with a lower neck load-cell. 2.3.6. The angle between the two faces of the neck-bracket is 25°. Because the shoulder block is inclined 5° backwards, the resulting angle between the neck and torso is 20°.

The number of the table of contents of the technical drawing is: No. E-AA-DRAWING-LIST-7-25-032 dated on 25 July 2003. The complete set of ES-2 technical drawings and the ES-2 User Manual are deposited with the United Nations Economic Commission for Europe (UNECE), Palais des Nations, Geneva, Switzerland and may be consulted on request at the secretariat. 2.3.6. The angle between the two faces of the neck-bracket is 25°. Because the shoulder block is inclined 5° backwards, the resulting angle between the neck and torso is 20°.

Neck. The neck can be adjusted by means of the chain tensioner (13). When the neck is adjusted, the upper end of the tensioner shall displace between 4-6 cm when subjected to a horizontal load of 10 xxX.

Neck. 2.3.1. The neck is shown as part No. 2 in figure 1 of this annex. 2.3.2. The neck consists of a head/neck interface piece, a neck/thorax interface piece and a central section that links the two interfaces to one another. 2.3.3. The head/neck interface piece (part No. 2a) and the neck/thorax interface piece (part No. 2c) both consist of two aluminium disks linked together by means of a half spherical screw and eight rubber buffers. 2.3.4. The cylindrical central section (part No. 2b) is made of rubber. 2.3.5. The neck is mounted on the neck-bracket, shown as part No. 3 in figure 1 of this annex. 2.3.6. The angle between the two faces of the neck-bracket is 25 degrees. Because the shoulder block is inclined 5 degrees backwards, the resulting angle between the neck and torso is 20 degrees.

Neck. 5.6.1. The head-neck interface of the neck is mounted to a special symmetrical certification headform with a mass of 3.9 ± 0.05 kg (see figure 4). 5.6.2. The headform and neck are mounted upside-down to the bottom of a neck-bending pendulum allowing a lateral motion of the system. 5.6.3. The neck-pendulum is equipped with a uniaxial accelerometer mounted at 1,655 ± 5 mm from the pendulum pivot. 5.6.4. The neck-pendulum should be allowed to fall freely from a height chosen to achieve an impact velocity of 3.4 ± 0.1 m/s measured at the accelerometer location. 5.6.5. The neck-pendulum is decelerated from impact velocity to zero by an appropriate device, resulting in a deceleration-time history inside the corridor specified in figure 5 of this annex. All channels have to be recorded using ISO CFC 1000 filters and filtered digitally using CFC 60. 5.6.6. The maximum headform flexion angle relative to the pendulum should be 51 ± 5 degrees and should occur between 50 and 62 ms. 5.6.7. The maximum headform centre of gravity displacements in the lateral and vertical direction should be 97 ± 10 mm and 26 ± 6 mm respectively. 5.6.8. The neck performance can be adjusted by replacing the circular section buffers with buffers of a different shore hardness.
