Test Procedures
2.1 Apply the forces specified in subsections 207(l)(a)(i)(A) and
207(l)(a)(i)(B) of Section 207 of Schedule IV to the Motor Vehicle Safety
Regulations as follows:
2.1.1 If the seat back and the seat bench are attached to the vehicle
by the same attachments, secure a strut on each side of the seat from
a point on the outside of the seat frame in the horizontal plane of the
centre of gravity of the seat to a point on the frame as far forward as
possible of the seat anchorages. Between the upper ends of the struts,
place a rigid cross-member, in front of the seat back frame for rearward
loading and behind the seat back frame for forward loading. Apply the
force specified by subsections 207(l)(a)(i)(A) or 207(1)(a)(i)(B) of Schedule
IV to the Motor Vehicle Safety Regulations horizontally through the rigid
cross-member, as shown in Figure 1.

2.1.2 If the seat back and the seat bench are attached to the vehicle
by different attachments, attach to each component a fixture capable of
transmitting a force to that component. Apply forces equal to 20 times the
weight of the seat back horizontally through the centre of gravity of the
seat back, as shown in Figure 2, and apply forces equal to 20 times the
weight of the seat bench horizontally through the centre of gravity of the
seat bench, as shown in Figure 3.
