Foreword
Chapter 4, 5, 6 to 7 of this Standard is mandatory and the rest are recommended.
This Standard is drafted according to the rules specified in GB/T 1.1-2009.
This Standard replaces GB14166-2003 Safety-belts and Restraint Systems for Occupants
of Power-driven Vehicles.
The main differences between this Standard and GB14166-2003.
a) MODIFY the name of the standard
MODIFY the name of the standard to be. Safety-belts, restraint systems, child restraint
systems and ISOFIX child restraint systems for occupants of power-driven vehicles (the
former name was. Safety belt and restraint system for adult occupants of power-driven
vehicles).
b) MODIFY the scope of application of the standard;
 For the M, N types vehicles; there are belts and restraint system solely used as
independent equipment for the adult occupants on forward-facing or rearward-facing seats.
 The M, N type’s vehicles are equipped with belts and restraint system solely used as
independent equipment for the adult occupants on forward-facing or rearward-facing seats.
 The M1 type and N1 type vehicles are equipped with the child restraint system and
ISOFIX child restraint system.
 The M1 type vehicles are equipped with seatbelt reminder.
c) Retracting force
The measurement requirements of retracting force with tension-reduce device are
added. When measuring the retracting force under the operation condition of the tension-
reduce device, the retracting force can be reduced to 0.5 N; and if the retractor assembly
is equipped with tension-reduce device , before and after the durability test, the retracting
force of strap shall be measured when the tension-reduce device works and doesn’t work
(4.2.5.3.4 of this Edition).
d) Dynamic performance
 The dynamic performance requirements of the safety belt with pre-loading device are
modified. For safety belt with pre-loading device, the pre-loading device shall work in the
dynamic test (4.4.1.2 of this Edition). The 2003 edition requirements require that under the
two dynamic tests, the pre-loading device shall be tested respectively when it works and
doesn’t work (4.4.1.2.4 of 2003 edition).
 The dynamic performance requirements of the safety belt with tension-reduce device
are added. The tension-reduce device shall be gone through dynamic test in the operating
mode (4.4.1.2 of this Edition).
 The limit scope of displacement of the dummy’s reference point is modified. For
restraint system, when the top anchorage is installed on the seat, according to 4.5.4
reduction and exemption rules in the GB14167-2013, the displacement can be larger than
value specified in 4.4.1.3b) (4.4.1.5 of this Edition); and for harness belts, the minimum
displacement specified in 4.4.1.3 b) can be reduced by half [4.4.1.3b of 2003 edition]. The
dynamic test of 2003 edition does not contain the relevant reduction and exemption rules
for top anchorage of safety belt installed on the seat and the relevant regulations of harness
belts.
e) The test method available to take acceleration block device for dynamic test is added
(5.7.5 of this Edition). In the 2003 edition, there are only contents related to deceleration
block device.
f) The installation requirements of safety belt and restraint system on vehicles are added
(6 of this Edition).
g) Annex B is added which states the installation requirements of the adult safety belt
and restraint system of power-driven vehicle forward-facing seat as well as that of the
ISOFIX child restraint systems.
h) Annex N is added which states the minimum requirements of the safety belts and the
retractor.
i) Annex O is added which states the safety belt reminder device test.
j) Annex Q is added which sates the confirmed program of power-driven vehicle seating
position H point and the actual backrest angle, and the H point device that is described in
KSO6549.1999.
The technical differences between this Standard and ECE R16 regulations in the United
Regulations on Safety-Belts, Restraint Systems, Child Restraint Systems and ISOFIX
Child Restraint Systems for Occupants of Power-driven Vehicles (English version) and the
reasons are as follows.
a) The definition of 2.10 terms in ECE R16 is modified from the children restraint to child
restraint system and the definition in GB27887-2011 Restraint System Restraint System
for Child Occupant Power-driven Vehicle is directly adopted;
b) The retracting force bench test method (5.6.4.3 of this Edition) is added, as well as the
operability of the standard;
c) The "Certification application" in chapter 3 of ECE R16, "Marking" in chapter 4,
"Certification" in chapter 5, "Production consistency" in chapter 9, " Punishment on
production inconsistency" in chapter 10, " Changes and the extension of the vehicle models
or safety belts and restraint systems certification" in chapter 11, "Formal production
cessation" in chapter 12, "The names and addresses of the certification test departments
and administrative departments" in chapter 14, Annex 1 A " Notice of safety belt certification
approval, certification extension, certification rejection, certification revocation or official
cessation according to the ECE R16", Annex 1 B "Notice of certification approval,
certification extension, certification rejection, certification revocation or official cessation
related to power-driven vehicles belts and adult occupants restraint system according to
the ECE R16", Annex 2 "The arrangement example of the certification marks" related to
the contents of the certification program and certification marks was deleted. And the
reason was the differences in the form of standardized system and regulatory system.
Annex A describes the contrast list of the chapter and article numbers of this Standard and
ECE R16 regulations.
In order to be convenient, the following editorial modification was made in regulations part
of ECE R16.
a) "The regulations" is modified to "the standard";
b) cm2 is modified to mm2; daN is modified to N;
c) The informative Annex A is added.
This Standard was proposed by National Development and Reform Commis...
