Whiplash Testing Protocol - Euro NCAP

6.2.3.1.5.4 If there is no locking position before the lowest or stowed position is reached, then the
head restraint should be positioned fully down.
6.2.3.1.5.5 Once the vertical test position has been determined, ensure the head restraint is returned
to rearmost tilt position.

Example A
Locking position at
geometric mid point
Locking positions are indicated in orange
Example B
Locking position up to
10mm above geometric
mid point

Example C
Locking position more
than10mm above
geometric mid point
6.2.3.2.1 Following the setting of midrange height, the procedure should be repeated for locking
horizontal adjustments. For non-locking tilt adjustments, the head restraint should be
tilted fully rearward.
6.2.3.2.2 Mid tilt position may be influenced by the presence of the HRMD head, consequently the
setting of mid range tilt should be undertaken following successful installation of the
H-point machine and HRMD and should be completed while the equipment is still
installed in the seat.
6.2.3.2.3 For HRMDs equipped with probes having 5mm increments only, a more accurate
measurement technique is required to establish the mid position to within 1mm. Using a
steel rule, measure the probe extension from the front of the headform at forward and
rearward tilt settings. From this data a midpoint target may be derived.
6.2.3.2.4 Most rearward tilt shall be made using HRMD probe backset. The most rearward tilt
position shall be that which results in greatest backset measurement. In the situation
where the head restraint cannot be placed at most rearward tilt. For example due to a
