Strength Test Conditions
2.1.1 The strength of the anchorages for a Type 1 manual seat belt
assembly or the pelvic portion of a Type 2 manual seat belt assembly that
is equipped with a detachable upper torso restraint shall be tested
(a) by placing the seat in its rearmost position on a plane parallel
to the longitudinal centreline of the vehicle,
(b) by positioning the pelvic body block illustrated in Figure 1
as specified in subsection 2.3 and by restraining the pelvic body block
by:
(i) a Type 1 manual seat belt assembly,
(ii) the pelvic portion of a Type 2 manual seat belt assembly,
or
(iii) material whose breaking strength is equal to or greater
than the breaking strength of the webbing for the seat belt assembly
that was installed as original equipment at that seating position,
provided that, at the initiation of the test, the geometry and the
attachment duplicate those of the originally installed seat belt assembly,
and
(c) by applying and maintaining a force of 22 240 N to
the pelvic body block for 10 seconds in the direction in which
the seat faces,
(d) with the initial application angle of the force being not less
than 5° and not more than 15° above the horizontal plane and
(e) with the onset rate of the force being not more than 222 400 N/s
so as to attain the 22 240-N force in not more than 30 seconds.

2.1.2 Alternative Pelvic Body Block
In order to apply a force to the centre set of anchorages for a group
of three or more adjacent sets of anchorages, the alternative pelvic body
block illustrated in Figure 2 may, at the option of the manufacturer,
be substituted for the pelvic body block illustrated in Figure 1.

2.2.1 The strength of the anchorages for the pelvic portion and the
upper torso portion of a Type 2 manual seat belt assembly shall be tested
(a) by placing the seat in its rearmost position on a plane parallel
to the longitudinal centreline of the vehicle,
(b) by positioning the body block as specified in subsection 2.3
and by restraining the pelvic body block by a Type 2 manual seat
belt assembly as follows:
(i) the pelvic body block illustrated in Figure 1 or, for a centre
seating position, at the option of the manufacturer, the alternative
pelvic body block illustrated in Figure 2 and
(ii) the upper torso body block illustrated in Figure 3,
(c) by applying and maintaining a force of 13 344 N simultaneously
to each body block for 10 seconds in the direction in which the seat
faces,
(d) with the initial application angle of the force being not less
than 5° and not more than 15° above the horizontal plane, and
(e) with the onset rate of the force being not more than 133 440 N/s
so as to attain the 13 344-N force in not more than 30 seconds.

2.3.1 Place a 50th percentile adult male anthropomorphic
test device (ATD) at each seating position and fasten the seat belt around
it, removing all slack from the webbing. Place a mark on the seat belt
webbing to indicate how far the seat belt extends from the retractor.
Unbelt and remove the ATDs from the vehicle.
2.3.2 Place the body blocks against the back of the seat and fasten
the seat belts around them. If, at this position, the belt buckle appears
to be susceptible to damage from the test loads, move the body blocks
forward, but not further than the mark made by following the procedure
specified in subsection 2.3.1, in order to minimize the likelihood of
buckle damage.
