Whiplash Testing Protocol - Euro NCAP

4.6.2.7 Seat adjustments not set in steps 4.6.2.2 through 4.6.2.6 should remain in the initial
adjustment as set in section 4.5.1.
4.7 Seat Belt
4.7.1 A generic three point lap-shoulder seat belt equipped with an inertia reel should be used
during the test, placed in such a way that the belt, when worn by the ATD, should lie across
the torso, clavicle and pelvis, and must always be routed above the pelvic angle gauge.
4.7.2 For generic seat belts, where a seat is equipped with anchorages or buckles, these may be
used. Any anchorages not attached to the seat should be positioned as shown in Figure 6. The
marks, which correspond to the arrangement of the anchorages, show where the ends of the
belt are to be connected to the sled. The anchorages are the points A, B and K. The tolerance
on the position of the anchorage points is such that each anchorage point should be situated at
most at 50mm from corresponding points A, B and K indicated in Figure 6.
4.7.3 If a fourth anchorage is necessary to attach the retractor, this anchorage:
should be located in the vertical longitudinal plane passing through K,
should be located 770mm vertically below K.
In the case of a belt equipped with a belt adjustment device for height, this device should be
secured to a rigid frame.
4.7.4 The structure carrying the anchorages must be rigid and should be so constructed that no
permanent deformation shall occur in the parts bearing the anchorages during the test.

4.7.5 Where a manufacturer requests and can demonstrate good reason for doing so to the
Secretariat, vehicle specific belts and geometry may be considered. In this case or when
testing seats equipped with integrated belts the vehicles own seat belt hard ware (retractor and
buckle) should be used. Seat belt geometry and restraint equipment should then be used that
