(e) retain the torso of the anthropomorphic test device within the restraint system, and not allow any portion of the target points on either side of the device’s head, located on the transverse axis passing through the centre of mass of the device’s head and perpendicular to the head’s midsagittal plane, to pass at any time, during or immediately after the test, either through the transverse orthogonal planes formed by the extension of the seat back frontal surface plane of the restraint system and by the plane that passes through the uppermost point of the restraint system, ...[+++] as shown in Figure 7 of Schedule 7, or through the vertical transverse plane passing through point X on the standard seat assembly, as shown in Figure 8 of Schedule 7;

(c) in the case of a restraint system other than a car bed, retain the torso of the anthropomorphic test device within the restraint system, and not allow any portion of the target points on either side of the device’s head, located on the transverse axis passing through the centre of mass of the device’s head and perpendicular to the head’s midsagittal plane, to pass at any time, during or immediately after the test, through the transverse orthogonal planes formed by the extension of the seat back frontal surface plane of the restraint system and by the plane that passes thr ...[+++]ough the uppermost point of the restraint system, as shown in Figure 7 of Schedule 7, or through the vertical transverse plane passing through point X on the standard seat assembly, as shown in Figure 8 of Schedule 7;

(2) A forward-facing child restraint system is not required to conform to the requirements of paragraphs 215(1)(e) and (f) if the target point located on either side of the head of the heaviest of the anthropomorphic test devices used in the dynamic test — other than an anthropomorphic test device specified in subpart I, N or S, part 572, chapter V, title 49 of the Code of Federal Regulations of the United States (revised as of October 1, 2012) — and located on the transverse axis passing through the centre of mass ...[+++] of the device’s head and perpendicular to the head’s midsagittal plane is below a horizontal plane tangent to the top of the standard seat assembly when the anthropomorphic test device is positioned in the restraint system in accordance with subsection 4.4.2 or 4.5.2 of Test Method 213 and the restraint system is installed on the standard seat assembly in accordance with subsection 4.4.1 or 4.5.1 of Test Method 213.
