3.11
Type of a protective system
A type of protection device that does not differ in the following main aspects.
3.16.1
Ignition key
A device that controls the power required to operate an automobile engine
or motor. This definition also includes non-mechanical devices.

4 Requirements
4.1 The internal components of the passenger compartment in front of the
front seat?€?s ?€?H?€? point and above the level of the instrument panel
(excluding the side door)
4.1.1 In the reference zone as defined in 3.3, there shall be no dangerous rough
surfaces or sharp edges that may increase the risk of serious injury to the
occupant. If the head collision zone is determined according to Appendix C, the
components described in 4.1.2 ~ 4.1.6 below shall be considered to meet the
requirements of 4.1.4 and 4.1.5. Alternatively, according to the procedure as
described in Appendix G, sufficient tests shall be used to demonstrate that
during the collision test, it will not contact the bracket due to cut off the soft
material which has a Shore (A) hardness below 50. In this case, the radius
requirement does not apply (see the note to 4.1.6 in Appendix D).
4.1.7 If the dynamic reference zone is determined according to Appendix B, it
shall meet the following requirements.
4.1.7.1 If the protective system of the vehicle cannot prevent the head of the
dummy (as specified in B.1.2.1 of Appendix B) from coming into contact with
the instrument panel, thus the dynamic reference zone is determined according
to Appendix B, then the requirements of 4.1.2 ~ 4.1.6 apply only to parts located
in this zone.
Parts of other areas of the instrument panel above the level of the instrument
panel shall, if in contact to the sphere which has a diameter of 165 mm, be at
least rounded.
4.1.7.2 If the protective system of this vehicle model is capable of preventing
the contact of the head of the dummy (as specified in B.1.2.1 of Appendix B)
with the instrument panel, thereby determining that there is no reference zone,
then the requirements of 4.1.2 ~ 4.1.6 do not apply to this vehicle model.
Parts above the level of the instrument panel shall, if in contact to the sphere
which has a diameter of 165 mm, be at least rounded.
4.2 The internal components of the passenger compartment in front of the
?€?H?€? point of the front seat and below the level of the instrument panel
(excluding the side door and the foot pedal)
4.2.1 Except for the foot pedal and its fixtures as well as the components that
are not accessible to the devices and operating procedures as described in
Appendix H, the various components (switches, ignition keys, etc.) involved in
4.2 shall comply with the provisions of 4.1.4 ~ 4.1.6 (see the note to 4.2.1 in
Appendix D).
4.2.2 If the hand brake lever is mounted above or below the instrument panel,
when it is in the released position, even if a frontal collision occurs, it is
impossible for the occupant to touch it. Otherwise, the surface of the brake lever
shall meet the requirements of 4.3.2.3 (see the note to 4.2.2 in Appendix D).
4.2.3 When designing and manufacturing shelves or other similar components,
ensure that the brackets have no raised edges and that one of the following
requirements is met (see the note to 4.2.3 in Appendix D).
4.2.3.1 The part of the shelf or other similar component facing the interior of the
4.3.2.2 The joystick and push button shall be designed and constructed to
ensure that, when subjected to a 378 N forward longitudinal horizontal force,
the protrusion at the most unfavorable position of the human body shall fall
within 25 mm to the surface of panel or fall off or bend or deform. When it falls
off or bends, no dangerous protrusion shall be left in the original position.
However, the joystick of the glass lifter is allowed to protrude 35 mm from the
surface (see the note to 4.3.2.2 in Appendix D).
4.3.2.3 When the hand brake lever is in the released position and the shift lever
is in any forward gear, unless in the area as specified in 3.3a) and b) or below
the horizontal plane which passes through the ?€?H?€? point of the front seat,
otherwise the cross-sectional area at a point 6.5 mm away from the most
convex part in the longitudinal direction shall not be less than 650 mm2, the
radius of curvature shall not be less than 3.2 mm (see the note to 4.3.2.3 in
Appendix D).
4.3.3 The requirements of 4.3.2.3 above do not apply to hand brake levers
which are mounted on the floor; for such hand brake levers, when in the
released position, if the height of any part of the joystick is above the horizontal
plane passing through the lowest ?€?H?€? point of the front seat, then the cross-
sectional area as measured on the horizontal plane not more than 6.5 mm (as
measured along the perpendicular direction) away from the apex of the
protrusion is at least 650 mm2. The radius of curvature shall be not less than
3.2 mm.
4.3.4 For other vehicle components not covered by the above, such as seat
rails, horizontal and vertical adjustment mechanism of seat, seat belt retractor,
etc., if the position of these components is lower than the horizontal plane which
passes through the ?€?H?€? point of each seat, even if they can be reached by the
occupant, they are not subject to these terms (see the note to 4.3.4 in Appendix
D).
4.3.4.1 Components that are mounted on the roof but are not part of the roof
structure, such as handles, roof lights, sun visors, etc., shall have a radius of
curvature of not less than 3.2 mm. The width of the protrusion shall not be less
than the downward protrusion; or, these protrusions shall pass the energy
absorbing test as specified in Appendix G (see the note to 4.3.4.1 in Appendix
D).
4.3.5 For some components which are made of a soft material with a Shore (A)
hardness of less than 50 and which are mounted on a rigid support, the rigid
support shall meet the above requirements. Alternatively, according to the
procedure described in Appendix G, sufficient tests shall be used to
demonstrate that such components will not touch the frame during the collision
test due to cutting off the soft material which has a Shore (A) hardness below
50. In this case, the radius requirement does not apply.
be in an area that cannot be reached by a sphere which has a diameter of 165
mm. If this condition cannot met, then the opening mechanism and the
operating mechanism are either in the retracted state when they are in the stop
position; or the design and manufacture of these mechanisms meet the
following requirements. when subjected to a force of 378 N in the impact
direction along a trajectory of the ball-head model path (according to the
provisions of Appendix G), the protrusion height (measured according to the
measurement method of Appendix F) falls within 25 mm from the mounting
surface of the mechanism; or there shall be no remaining protrusions at the
original position after falling off (see the note to 4.5.1.2.3 in Appendix D).
4.5.2 Power-operated roof-panel system and its operating parts shall meet the
requirements of 4.8 below.

4.6.1 For convertible cars, the lower edge of the upper part of the rollover
protection bracket and the upper part of the windshield frame shall meet the
requirements of 4.4 in all normal use positions. Folding bars or connectors
located above or in front of the occupant to support the non-rigid roof shall have
neither rearward or downward dangerous rough surfaces nor sharp edges (see
the note to 4.6.1 in Appendix D).

determined in Appendix C) within the boundaries specified in 4.7.1.2.1 and
4.7.1.2.2 shall meet the energy absorption performance as specified in
Appendix G. To determine the head collision zone, if the front seats are
adjustable, they shall be in the rearmost driving position, the backrest angle
shall be as close as possible to 25??, unless otherwise specified by the
manufacturer (see the note to 4.7.1.2 in Appendix D).
4.7.1.2.1 For free-standing front seats, the rear passenger?€?s head collision zone
shall be within the area at the top of the backside of the front seat backrest
