PROPOSAL FOR THE 02 SERIES OF AMENDMENTS TO
REGULATION NO. 129
(ENHANCED CHILD RESTRAINT SYSTEMS (ECRS))
ADOPTED AT THE 170 SESSION – NOVEMBER 2016
PROVISIONAL DATE OF ENTRY INTO FORCE: JUNE 22, 2017

Insert a new Paragraph 2.17.2., to read:
"2.17.2. " i-Size booster seat fixture" means a fixture, of the dimensions given in Figure 1 of
Annex 17, Appendix 5 of Regulation No. 16 and used by an Enhanced Child Restraint
System manufacturer to determine the appropriate dimensions of a i-Size booster seat
and its compatibility with most vehicle seating positions and, in particular, those which
have been assessed without ISOFIX attachments, according to Regulation No. 16 as
being compatible with such a category of an Enhanced Child Restraint System.
Paragraph 2.51., amend to read:
"2.51. "ECRS Position"
2.51.1. "ISOFIX position" means a location as defined in Paragraph 2.17. of
Regulation No. 14.

manufacturer, which is designed to accommodate any i-Size Enhanced Child Restraint
System, as defined in this Regulation."
Insert new Paragraphs 2.56. to 2.56.2., to read:

adult safety-belt relative to another section of the webbing of the same belt. Such
devices may act upon either the diagonal or the lap sections or secure together both
lap and diagonal sections of the adult belt. The term covers the following classes:
2.56.1. "Class A device" prevents the child from pulling the webbing of the retractor through
to the lap part of the belt, when the adult belt is used to restrain the child directly.
2.56.2. "Class B device" (to be used in Phase III) allows the retention of an applied tension in
the lap part of an adult safety-belt, when the adult belt is used to restrain the Enhanced
Child Restraint System. The device intends to prevent the webbing from slipping from
the retractor through the device, which would release the tension and place the
restraint in a non-optimal position."

The deceleration of the trolley shall be achieved by using the apparatus prescribed in
Annex 6 to this Regulation or any other device giving equivalent results. This apparatus
shall be capable of the performance specified in Paragraph 7.1.3.4. and hereafter
specified:
For frontal impact, the trolley shall be so propelled that, at the beginning of the test, its

graph in Annex 7, Appendix 2.
In addition to fulfilling the above requirements, the Technical Service shall use a mass
of trolley (equipped with its seat), as specified in Paragraph 1. of Annex 6, greater than
380kg.
However, if the tests above were performed at a higher speed and/or the acceleration
curve has exceeded the upper level of the hatched area and the child restraint meets
the requirements, the test shall be considered satisfactory.
It is however permitted the deceleration curve exceeds the lower boundaries of the
performance requirements but for a cumulative period less than 3ms time;"

anchorages shall be permitted to draw the unoccupied Enhanced Child Restraint
System towards these anchorages. An additional force of 135 +/-15N shall be applied
in a plane parallel to the surface of the test bench seat cushion. The force shall be
applied along the centre line of the Enhanced Child Restraint System and at a height of
no more than 100mm above the test bench seat cushion.
The dummy shall be placed in the Enhanced Child Restraint System.
Figure 1
Load Cell Positions
Fit load cell 1 to the outboard position as shown Figure 1. Install the Enhanced Child
Restraint System in the correct position. If a lock-off device is fitted to the Enhanced
Child Restraint System and acts upon the diagonal belt, place load cell 2 at a
convenient position behind the Enhanced Child Restraint System between the lock-off
device and the buckle as shown above. If no lock-off device is fitted or if the lock-off
device is fitted at the buckle, position the load cell at a convenient position between the
pillar loop and the Enhanced Child Restraint System.
Adjust the lap portion of the reference belt to achieve a tension load of 50N ± 5N at
Load Cell 1. Make a chalk mark on the webbing where it passes through the simulated
buckle.
While maintaining the belt at this position, adjust the diagonal to achieve a tension of
50N ± 5N at Load Cell 2 by either locking the webbing at the Enhanced Child Restraint
System webbing locker or by pulling the belt between the belt clamping mechanism
and the standard retractor. If the tension in Load Cell 2 is achieved by pulling the belt
between the clamping mechanism and the retractor, the clamping mechanism shall
now be locked.
Extract all webbing from the retractor spool and rewind the excess webbing keeping a
tension of 4 ± 3N in the belt between the retractor and the pillar loop. The spool shall
be locked before the dynamic test. Conduct the dynamic crash test.

Paragraph 7.1.3.6., amend to read:
"7.1.3.6. Size Indication
The dynamic tests shall be conducted with the largest dummy and the smallest dummy
as defined in the following tables according to the size range indicated by the
manufacturer for the Enhanced Child Restraint System.

Paragraphs 7.3. to 7.3.3., amend to read:
"7.3. Certification of Test Bench Cushion
7.3.1. The test bench cushion shall be certified when new to establish initial values for impact
peak deceleration, and then after every 50 dynamic tests or at least every month,
whichever is the sooner.
7.3.2. The certification and measuring procedures shall correspond to those specified in the
latest version of ISO 6487; the measuring equipment shall correspond to the
specification of a data channel with a channel filter class (CFC) 60.
Using the test device defined in Annex 14 to this Regulation, conduct three tests on the
bench base prepared as described in Annex 6, foam covered with textile, 150 ± 5mm
from the front edge of the cushion on the centre line and at 150 ± 5mm in each
direction from the centre line.
Place the bench cushion on a flat rigid surface. Place the device vertically above the
test point, at a height of 500 ± 5mm and allow it to fall freely to make impact on the seat
surface. Record the deceleration curve.
7.3.3. The initial peak recorded values for impact deceleration shall be 24 ± 4g and
subsequent peak values recorded shall not deviate by more than 15% from the initial
values."

Insert new Paragraphs 16.5. to 16.7., to read:
