    (g) Each add-on child restraint system manufactured for use in
motor vehicles, that is recommended for children in a weight range that
includes weights less than 18 kilograms (40 pounds) regardless of
height, or for children in a height range that includes heights less
than 1100 millimeters regardless of weight, shall meet the requirements
in this standard and the applicable side impact protection requirements
in Standard No. 213a (Sec.  571.213a).
    S5.1 Dynamic performance.
    S5.1.1 Child restraint system integrity. When tested in accordance

with S6.1, each child restraint system shall meet the requirements of
paragraphs (a) through (c) of this section.
    (a) Exhibit no complete separation of any load bearing structural
element and no partial separation exposing either surfaces with a
radius of less than \1/4\ inch or surfaces with protrusions greater
than \3/8\ inch above the immediate adjacent surrounding contactable
surface of any structural element of the system.
    (b)(1) If adjustable to different positions, remain in the same
adjustment position during the testing that it was in immediately
before the testing, except as otherwise specified in paragraph (b)(2).
    (2)(i) Subject to paragraph (b)(2)(ii) of this section, a rear-
facing child restraint system may have a means for repositioning the
seating surface of the system that allows the system's occupant to move
from a reclined position to an upright position and back to a reclined
position during testing.
    (ii) No opening that is exposed and is larger than \1/4\ inch
before the testing shall become smaller during the testing as a result
of the movement of the seating surface relative to the restraint system
as a whole.
    (c) If a front facing child restraint system, not allow the angle
between the system's back support surfaces for the child and the
system's seating surface to be less than 45 degrees at the completion
of the test.

dummies specified in S7, each child restraint system shall:
    (a) Limit the resultant acceleration at the location of the
accelerometer mounted in the test dummy head such that, for any two
points in time, t1 and t2, during the event which are separated by not
more than a 36 millisecond time interval and where t1 is less than t2,
the maximum calculated head injury criterion (HIC36) shall not exceed
1,000, determined using the resultant head acceleration at the center
of gravity of the dummy head, a, expressed as a multiple of g (the
acceleration of gravity), calculated using the expression below. The
HIC calculation shall be calculated within the first 175 milliseconds
of the sled acceleration that is within the acceleration corridor in
Figure 2, when testing with the HIII-6YO dummy in a backless child
restraint system.

front-facing child restraint system, and the conformance of any child
restraint system other than a car bed to those requirements, is
determined using the largest of the test dummies specified in S7 for
use in testing that restraint, provided that the 6-year-old dummy
described in subpart I or subpart N of part 572 of this title and the
10-year-old dummy described in subpart T of part 572 of this title, are
not used to determine the applicability of or compliance with S<IP_ADDRESS>.
A front facing child restraint system is not required to comply with
S<IP_ADDRESS> if the target point on either side of the dummy's head is
below a horizontal plane tangent to the top of--
    (a) The standard seat assembly, in the case of an add-on child
restraint system, when the dummy is positioned in the system and the
system is installed on the assembly in accordance with S6.1.2.

than a car bed shall comply with the applicable requirements of
S<IP_ADDRESS> and S<IP_ADDRESS>.
    S<IP_ADDRESS> (a) The system surface provided for the support of the
child's back shall be flat or concave and have a continuous surface
area of not less than 85 square inches.
    (b) Each system surface provided for support of the side of the
child's torso shall be flat or concave and have a continuous surface of
not less than 24 square inches for systems recommended for children
weighing 20 pounds or more, or 48 square inches for systems recommended
for children weighing less than 20 pounds.

    (c) Each horizontal cross section of each system surface designed
to restrain forward movement of the child's torso shall be flat or
concave and each vertical longitudinal cross section shall be flat or
convex with a radius of curvature of the underlying structure of not
less than 2 inches.
    S<IP_ADDRESS> Each forward-facing child restraint system shall have no
fixed or movable surface--
    (a) Directly forward of the dummy and intersected by a horizontal
line--
    (1) Parallel to the SORL, in the case of the add-on child restraint
system, or
    (2) Parallel to a vertical plane through the longitudinal center
line of the vehicle seat, in the case of a built-in child restraint
system, and,
    (b) Passing through any portion of the dummy, except for surfaces
which restrain the dummy when the system is tested in accordance with
S6.1.2(a)(2), so that the child restraint system shall conform to the
requirements of S5.1.2 and S<IP_ADDRESS>.

    S<IP_ADDRESS> [Reserved.]
    S<IP_ADDRESS> The webbing of belts provided with a child restraint
system and used to attach the system to the vehicle or to restrain the
child within the system shall--
    (a) Have a minimum breaking strength for new webbing of not less
than 15,000 N in the case of webbing used to secure a child restraint
system to the vehicle, including the tether and lower anchorages of a
child restraint anchorage system, and not less than 11,000 N in the
case of the webbing used to secure a child to a child restraint system
when tested in accordance with S5.1 of FMVSS No. 209. Each value shall
be not less than the 15,000 N and 11,000 N applicable breaking strength
requirements, but the median value shall be used for determining the
retention of breaking strength in paragraphs (b)(1) and (c)(1) and (2)
of this section. ``New webbing'' means webbing that has not been
exposed to abrasion, light or micro-organisms as specified elsewhere in
this section.
    (b)(1) After being subjected to abrasion as specified in S5.1(d) or
S5.3(c) of FMVSS 209 (Sec.  571.209), have a breaking strength of not
less than 75 percent of the new webbing strength, when tested in
accordance with S5.1(b) of FMVSS 209.
    (2) A mass of 2.35 .05 kg shall be used in the test
procedure in S5.1(d) of FMVSS 209 for webbing, including webbing to
secure a child restraint system to the tether and lower anchorages of a
child restraint anchorage system, except that a mass of 1.5 .05 kg shall be used for webbing in pelvic and upper torso
restraints of a

belt assembly used in a child restraint system. The mass is shown as
(B) in Figure 2 of FMVSS 209.
    (c)(1) After exposure to the light of a carbon arc and tested by
the procedure specified in S5.1(e) of FMVSS 209 (Sec.  571.209), have a
breaking strength of not less than 60 percent of the new webbing, and
shall have a color retention not less than No. 2 on the AATCC Gray
Scale for Color Change (incorporated by reference, see Sec.  571.5).
    (2) After being subjected to micro-organisms and tested by the
procedures specified in S5.1(f) of FMVSS 209 (Sec.  571.209), shall
have a breaking strength not less than 85 percent of the new webbing.
    (d) If contactable by the test dummy torso when the system is
tested in accordance with S6.1, have a width of not less than 1\1/2\
inches when measured in accordance with S<IP_ADDRESS>.
    S<IP_ADDRESS> Width test procedure. Condition the webbing for 24 hours
in an atmosphere of any relative humidity between 48 and 67 percent,
and any ambient temperature between 70[deg] and 77 [deg]F. Measure belt
webbing width under a tension of 5 pounds applied lengthwise.
    S5.4.2 Belt buckles and belt adjustment hardware. Each belt buckle
and item of belt adjustment hardware used in a child restraint system
shall conform to the requirements of S4.3(a) and S4.3(b) of FMVSS No.

system and that is designed to restrain a child using the system shall
be adjustable to snugly fit any child whose height and weight are
within the ranges recommended in accordance with S5.5.2(f) and who is
positioned in the system in accordance with the instructions required
by S5.6.
    S<IP_ADDRESS> Direct restraint. Except for belt-positioning seats, each
belt that is part of a child restraint system and that is designed to
restrain a child using the system and to attach the system to the
vehicle, and each Type 1 and lap portion of a Type 2 vehicle belt that
is used to attach the system to the vehicle shall, when tested in
accordance with S6.1, impose no loads on the child that result from the
mass of the system, or--
    (a) In the case of an add-on child restraint system, from the mass
of the seat back of the standard seat assembly specified in S6.1, or
    (b) In the case of a built-in child restraint system, from the mass
of any part of the vehicle into which the child restraint system is
built.
    S<IP_ADDRESS> Seating systems. Except for child restraint systems
subject to S<IP_ADDRESS>, each child restraint system that is designed for
use by a child in a seated position and that has belts designed to
restrain the child, shall, with the test dummy specified in S7
positioned in the system in accordance with S10 provide:
    (a) Upper torso restraint in the form of:
    (i) Belts passing over each shoulder of the child, or
    (ii) A fixed or movable surface that complies with S<IP_ADDRESS>(c), and
