PROPOSAL FOR SUPPLEMENT 10 TO THE 04 SERIES OF
AMENDMENTS TO
REGULATION NO. 44
(CHILD RESTRAINT SYSTEMS)
ADOPTED AT THE 167 SESSION – NOVEMBER 2015
PROVISIONAL DATE OF ENTRY INTO FORCE: JUNE 18, 2016

Paragraph 7.1.4.1.10.1.2., amend to read:
"7.1.4.1.10.1.2. Without the anti-rotation device in use. If the anti-rotation device is a support leg and
it can be completely recessed within the base or the shell of the CRS, the test is
conducted with the device in its stowed position or with the leg removed respectively.
If it cannot be completely recessed within the base, the test is performed with the
device deployed in its shortest length with the trolley floor pan in its lowest position.
This requirement does not apply when a permanent and non-adjustable support leg is
used as an anti-rotation device."
Paragraph 8.1.3.6.3.2., amend to read:
"8.1.3.6.3.2. Place the child chair on the test seat.
Place the manikin in the child chair.
For restraints or straps acting directly on a retractor or adult three point safety belt,
where no lock off device or any system able to inhibit the action of the retractor is
used:
(a)
(b)
Fit the belt in accordance with the manufacturer's instructions.
Complete the installation of the child chair to the test seat in accordance with
Annex 21 to this Regulation.
For all other restraints:
(a)
(b)
(c)
(d)
Place a hinged board or a similar flexible device 2.5cm thick and 6cm wide and
of length equal to the shoulder height (sitting, Annex 8) less the hip centre
height (sitting, in Annex 8 popliteus height plus half of thigh height, sitting)
relevant to the manikin size being tested between the manikin and the seat
back of the chair. The board should follow as closely as possible the curvature
of the chair and its lower end should be at the height of the manikin's hip joint.
Adjust the belt in accordance with the manufacturer's instructions, but to a
tension of 250 ± 25N above the adjuster force, with a deflection angle of the
strap at the adjuster of 45 ± 5°, or alternatively, the angle prescribed by the
manufacturer.
Complete the installation of the child chair to the test seat in accordance with
Annex 21 to this Regulation.
Remove the flexible device."

Annex 5, amend to read:
"ANNEX 5

ANNEX 15
Insert new explanatory notes on Paragraphs 7.1.4.1.4., 7.1.4.1.10.1.2., 8.1.3.6.3.2. and 10.1.3., to read:
"Paragraph 7.1.4.1.4.
The Paragraph aims to ensure that the CRS will sustain all imposed loads during the dynamic test,
keeping the child in position, by maintaining the original position and configuration. Any change in the
original configuration, including change in the reclining position or in the support leg length shall be
considered a failure. Any load bearing part or component failure, like adult safety belt contact points
(identified as a belt route), anti-rotation device or CRS chair shell shall be considered a failure, except
where such behaviour is clearly identified as load limiting device function.
Paragraph 7.1.4.1.10.1.2.
Completely recessed means that with the leg in the stowed position, no part of the leg protrudes beyond
the surface of the base or shell, such that it has no effect on the position of the CRS on the test bench.
See the following figures for clarification examples.
