Proposal for the 02 series of amendments to Phase 2 of
Regulation No. 129 (Enhanced Child Restraint Systems)
Submitted by the expert from France*
The text reproduced below was prepared by the expert from France. It introduces the
02 series of amendments to UN Regulation No. 129 (Enhanced Child Restraint System
(ECRS)) that were agreed upon by the experts of the Informal Working Group on Child
Restraint Systems (IWG CRS). It supersedes ECE/TRANS/WP.29/GRSP/2015/09 and it is
based on an informal document GRSP-57-20 distributed at the fifty-seventh session of the
Working Party on Passive Safety (GRSP). The modifications to the existing text of the UN
Regulation,
including
the
draft
01
series
of
amendments
(ECE/TRANS/WP.29/GRSP/2015/24), are marked in bold for new or strikethrough for

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 ± 3 N in the belt between the retractor and the pillar
loop. The spool shall be locked before the dynamic test. Conduct the
dynamic crash test.

After installation
After installation, the dummy position shall be adjusted so that:
The dummy centre line and the Enhanced Child Restraint System centre line
shall be aligned exactly with the centre line of the test bench.
The arms of the dummy shall be positioned symmetrically. Elbows shall be
positioned in such a way that the upper arms are closely aligned with the
sternum.

ECE/TRANS/WP.29/GRSP/2015/31
Hands shall be positioned on the thighs.
Legs shall be positioned parallel to one another or at least symmetrically.
For lateral impact, positive measures shall be taken to ensure the stability of
the dummy is maintained until t0 and this shall be confirmed using video
analysis. Any means used to stabilise the dummy before t0 shall not influence
the dummy kinematics after t0.
Because the foam of the test bench seat cushion will compress after
installation of the Enhanced Child Restraint System, the dynamic test shall be
conducted no more than 10 minutes after installation.
To allow the test bench seat cushion to recover, the minimum period between
two tests using the same test bench seat cushion shall be 20 minutes.
Example for arm alignment:
Arms are aligned with sternum
Arms are not aligned with sternum

Insert new Annex 23, to read:
"Annex 23
Standard safety-belt
1.
The safety-belt for the dynamic test and for the maximum length requirements
shall be made according to the configuration shown in Figure 1. These are a
three-point retracting belt system.
2.
The three-point retracting belt has the following rigid parts: a retractor (R), a
pillar loop (P), two anchorage points (A1 and A2) (see Figure 1), and a central
part (N, in detail in Figure 3). The retractor shall comply with the requirements
of Regulation No. 16 (paragraph 6.2.5.2.2.) for retraction force. The retractor
spool diameter is 33 ± 0.5 mm [(example is given in Mutual Resolution No. 1
(M.R.1))].
3.
The retracting belt shall be fitted to the anchorages on the test bench, described
in Annex 6, Appendix 2 as follows:
(a)
Belt anchorage A1 shall be fitted to trolley anchorages B0 (outboard);
(d)
(b)
Belt anchorage A2 shall be fitted to trolley anchorage A (inboard);
(c)
Belt pillar loop P shall be fitted to trolley anchorage C;
Belt retractor R shall be fitted to trolley anchorage such that the spool centre
line is positioned on Re.
The value of X in Figure 1 below is 200 ± 5 mm. The effective strap length
between A1 and the centre line of the retractor spool Re (when the webbing is
fully extracted including the minimum length of 150 mm for testing of
Enhanced Child Restraint System shall be [2820] ± 5 mm when measured in a
straight line without load and on a horizontal surface. This length may be
increased for the testing of restricted categories; for all categories with the
Enhanced Child Restraint System installed, there shall be a minimum of 150
mm of strap length on the retractor spool.
4.
18
The strap requirements for the belt as follows:
(a)
Material: polyester spinnblack;
(b)
Width: 48 +/- 2 mm at 10,000 N;
(c)
Thickness: 1.0 +/- 0.2 mm;
(d)
Elongation: 8 +/- 2 per cent at 10,000 N.

II. Justification
1.
The proposed amendment includes Enhanced Child Restraint Systems from the
booster seat category (booster seat with backrest) into the scope of UN Regulation No. 129.
This represents Phase 2 of the UN Regulation.
2.
The text includes all modifications proposed by GRSP up to and including its fiftyseventh session (Geneva, 18–22 May 2015) as well as those of the IWG CRS up to and
including its fifty-third session (London, 2 September 2015).
3.
The reference document is the original UN Regulation No. 129, Corrigendum 1,
Supplements 1, 2, 3 and 4 as well as the draft 01 series of amendments to the UN
Regulation (ECE/TRANS/WP.29/GRSP/2015/24) Phase 1.
