4 Technical Requirements
4.1 General Requirements
4.1.1 The backrest of passenger cars whose loading space is limited by backrests shall be tested
in accordance with 5.3 and satisfy the requirements of 4.2.
4.1.2 If the passenger cars (except multi-purpose passenger cars) with a loading space limited
by backrests are equipped with a partitioning system, they shall be tested in accordance with
5.3 and satisfy the requirements of 4.3; multi-purpose passenger cars with a loading space
limited by backrests shall at least be equipped with a partitioning system, and the partitioning
system shall be tested in accordance with 5.3 and satisfy the requirements of 4.3. If the multi-
purpose passenger cars cannot arrange test blocks in accordance with 5.2.3, then, it is
unnecessary to satisfy the above-mentioned requirements.
4.1.3 If the passenger cars (except multi-purpose passenger cars) with a loading space limited
by backrests are equipped with a lashing point, they shall be tested in accordance with 5.4 and
satisfy the requirements of 4.4; multi-purpose passenger cars with a loading space limited by
backrests shall at least be equipped with a lashing point, and the lashing point shall be tested in
accordance with 5.4 and satisfy the requirements of 4.4.
4.2 Backrests
4.2.1 The backrests shall satisfy the requirements of 4.2.2 and 4.2.3. Seat systems that satisfy
the requirements of GB 15083 are also deemed to comply with the requirements of this article.
4.2.2 The backrests assuming the function of loading space partitioning shall be designed to
have sufficient strength, so as to improve the protective capability against injuries to the
occupants caused by forward movement of cargo when the vehicle sharply decelerates.
4.2.3 During the test in 5.3, the test block shall be maintained behind the backrest, the locking
system of the backrest shall be maintained in the original position; the backrest, seat, anchorage,
adjustment system and displacement system are allowed to generate permanent deformation
that has no risk of injury to the occupants. After the test, there shall be no sharp corners or edges
that may increase the risk or degree of injury to the occupants.
4.3 Partitioning System
4.3.1 Occupants seated in the rearmost row of seats wit limited loading space shall be protected
by the partitioning system, so as to reduce injuries from moving luggage above the backrests.
4.3.2 During the test in 5.3, the test block shall be maintained behind the partitioning system
and / or integrated vehicle components. The partitioning system and / or integrated vehicle
components shall maintain in the original position and shall not become detached from their
anchor points.
4.3.3 During the test in 5.3, the front profile (see Figure 1) of the partitioning system and / or
integrated vehicle components shall satisfy the following requirements.
a) It shall not extend forward 300 mm beyond the transverse plane, which is tangent to
the rear edge of the backrest at its designed position.
b) If the forward movement exceeds 300 mm, the vehicle manufacturer shall prove that
there is no additional injury to the occupants (for example, with the help of high-speed
cameras). Under these circumstances, the front profile of parts of the partitioning
system and / or integrated vehicle components with a Shore A hardness greater than
50 shall not exceed the following planes:
---the transverse plane 100 mm in front of R-point;
---for head restraints that function partially or completely as a partitioning system, a
transverse plane 150 mm in front of R-point.
NOTE: for integral head restraints, the boundary between the head restraint and the backrest is
defined by a plane perpendicular to the reference line 540 mm from R-point.
4.3.4 The partitioning system is allowed to have permanent deformation or local damage, but
there shall be no sharp edges and / or falling components that may increase the risk of injury to
the occupants.
