Appendix B
(Normative)
Confirmation of dynamically determined head collision zone
B.1 Confirmation of the head collision zone dynamically determined by the
protection system
B.1.1 Unlike the procedure described in Appendix C, the applicant can
demonstrate through a procedure approved by the technical service
department responsible for the test management that the dynamically
determined head collision zone is relevant to the vehicle model.
B.1.2 A suitable method of testing the dynamically determined head collision
zone may be one of the following methods.
B.1.2.1 Real vehicle collision test
Regarding the protective system installed on this vehicle model, use at least
the collision speed of 48.3 km/h and the frontal collision conditions within the
range of ±30° with respect to the fixed rigid barrier wall, to determine the order
in which the occupants move. Usually a test of 0°, +30° and -30° is sufficient.
Use the 5th percentile female, the 50th percentile male, and the 95th percentile
male adult dummy to substitute the occupant, to evaluate the dynamically
determined head collision zone. Before the test, according to the requirements
of the manufacturer, place each dummy at the recommended seating position,
or.
B.1.2.2 Sled Tests
Under the effect of the deceleration-time diagram (change of velocity 50 km/h)
as shown in Figure F.1 of Appendix F of GB 14166 (or Appendix 8 of ECE R16),
make each dummy of the dummy family as specified above to be subjected to
movement which is equivalent to a frontal movement of the dummy in the real
vehicle’s frontal collision test (according to B.1.2.1), to investigate the sequence
of movement.
If the center line of the test object (usually the body-in-white) is within ±18° from
the longitudinal centerline of the sled, it is considered that the direction in which
the dummy moves forward is satisfactory. Usually the test of 0°, +18° and -18°
is sufficient, or.
B.1.2.3 Simulated collision test
Appendix C
(Normative)
Determination of head collision zone
C.1 The head collision zone consists of all non-glass surfaces inside the vehicle
that can be in static contact with a 165 mm diameter ball-head model which is
part of the measuring device. The size from the ankle articulation point to the
top of the ball-head model of this device can be continuously adjusted from 736
mm to 840 mm.
C.2 The head collision zone can be determined by the following procedure or
by using a mapping method.
C.2.1 For each seating position as specified by the manufacturer, place the
hinge point of the measuring device as follows.
C.2.1.1 Adjustable seat
C.2.1.1.1 Place it at the “H” point (see the Appendix C of GB 11551);
C.2.1.1.2 Place it at a point 127 mm in front of the “H” point, the height of this
point is the height of the “H” point after the seat moves forward for 127 mm, or
19 mm higher than the original “H” point (see the note to C.2.1.1.2 in Appendix
D).
C.2.1.2 Non-adjustable seat
Place it at the “H” point.
C.2.2 Within the internal dimensions of the vehicle, for each adjustable size
from the articulation point of the ankle to the top of the ball-head model, it shall
determine all contact points that can be measured by the measuring device in
front of the “H” point (see the note to C.2.2 in Appendix D).
Set the measuring arm of the measuring device to the minimum length and the
ankle joint to the “H” point of the rear seat. If the ball-head model exceeds the
front seat’s backrest, no contact point can be found in this measurement.
C.2.3 Place the measuring device in the vertical position and turn the measuring
device forward and downward in the vertical planes as close as possible to 90°
on both sides of the longitudinal vertical plane of the vehicle passing the “H”
point. Measure all the points that may be in contact.
To determine the point of contact, the length of the measuring arm of the
Appendix D
(Informative)
Notes to standard provisions and appendixes
D.1 Note to 3.3
The reference zone is determined without an interior rear-view mirror. The
energy absorption test is also performed without an interior rear-view mirror.
The pendulum shall not touch the mount of the interior rear-view mirror.
The exemption area behind the steering wheel as specified in these clauses is
equally valid for the front passenger's head collision zone.
For the adjustable steering wheel, there is an exemption area when the steering
wheel is in all possible driving positions, the final exemption area is reduced to
a common part of these areas.
Where a variety of steering wheels are available, the steering wheel which has
the smallest diameter, most unfavorable state shall be used to determine the
exemption zone.
D.2 Note to 3.4
The level of the instrument panel extends over the entire width of the passenger
compartment. When a plumb line moves in the width direction of the vehicle, it
is determined by the last tangent point of the plumb line and the surface of the
instrument panel. If there are two or more tangent points at the same time as
the plumb line and the surface of the instrument panel, it shall use the lower
tangent point to establish the level of the instrument panel; for the sub-
instrument panel, if the tangent point of the plumb line to the instrument panel
cannot be used to determine the level, it may use the intersection between the
horizontal line 25.4 mm higher above the “H” point of the front seats and the
sub-instrument panel to determine its level.
D.3 Note to 3.5
On both sides of the vehicle body, the roof shall start from the upper edge of
the door. Under normal circumstances, when the door is opened, the boundary
between the two sides of the roof is the outer contour as formed by the bottom
side (side view) of the remaining vehicle body. Above the window, the boundary
at side of the roof is a continuous transparent line (light transmission point of
the side window glass). For the pillar, the side boundary of the roof is the line
connecting the light transmission lines at both sides. For vehicles as defined in
If the protrusion of the ignition key’s handle is made of materials which have a
Shore (A) hardness of 60 ~ 80 and a thickness of at least 5 mm, or if all surfaces
are covered with at least 2 mm of this material, it is considered to meet the
requirements of this clause.
D.13 Note to 4.2.2
Determine if the hand brake lever can be touched as follows.
When the hand brake lever is located on or above the level of the instrument
panel (checked according to 4.1 in the collision zone), use the ball-head model
as specified in Appendix C.
When the hand brake lever is below the level of the instrument panel (in this
case, check the hand brake lever as specified in 4.3.2.3), use the knee model
as specified in Appendix H.
D.14 Note to 4.2.3
The provisions as stated in 4.2.3 also apply to the shelf and sub-instrument
panel in front of the front seat’s “H” point, below the level of the instrument panel,
between the front seats. If a cavity is closed, it can be regarded as a glovebox
and is not subject to these provisions.
D.15 Note to 4.2.3.1
The specified dimensions refer to the surface of the panel prior to covering a
material which has a Shore (A) hardness of less than 50 (see 4.2.4). The energy
absorption test is carried out according to the provisions of Appendix G.
D.16 Note to 4.2.3.2
If the shelf falls off or breaks, it shall not create a dangerous section. This
applies not only to the frame, but also to the other edges facing the passenger
compartment due to the force.
The part of shelf with the maximum strength shall be considered as the part
closest to the fixing device. In addition, under the effect of the applied force,
“significant deformation” shall mean the bending deformation of the shelf,
measured at the initial point of contact with the test cylinder, which shall be
visible folding or deformation visible to naked eyes. Elastic deformation is
allowed.
The length of the test cylinder is at least 50 mm.
D.17 Note to 4.3
