Motor Vehicle Safety Regulations — 213.4
ce to not more than 80 g, except for intervals of not more than 3 ms, unless it is established that any resultant acceleration above 80 g is caused by another part of the anthropomorphic test device striking its head; (g) not allow the angle between the back support surface and seating surface of the restraint system or booster seat to be less than 45° at the completion of the test; and (h) except in the case of a restraint system or booster seat tested with the anthropomorphic test device specified in subpart O or S, part 572, chapter V, Title 49 of the Code of Federal Regulations of the United States (revised as of October 1, 2012), limit the distance that either knee pivot can extend in a forward longitudinal direction, at any time during and immediately after the test, to not more than 305 mm from the pre-test position. (14) Every belt that is part of a built-in restraint system and that is designed to restrain a person in the restraint system shall not, when the restraint system is subjected to a dynamic test in accordance with section 5 of Test Method 213.4, impose on the anthropomorphic test device any loads that result from the mass of the restraint system or the mass of any part of the vehicle into which the restraint system is built. (15) The continuous seat back referred to in paragraphs (13)(c) and (d) shall have (a) a height (i) of at least 500 mm, in the case of a built-in restraint system recommended by the manufacturer for use only by persons whose mass is 18 kg or less, or (ii) of at least 560 mm, in the case of a built-in restraint system recommended by the manufacturer for use by a person whose mass is more than 18 kg; and (b) a width of at least 200 mm, measured in the horizontal plane at a height of 500 mm in the case of a built-in restraint system described in subparagraph (a)(i) or at a height of 560 mm in the case of a built-in restraint system described in subparagraph (a)(ii). (16) Subsection (15) does not apply in the case of (a) a built-in restraint system that is designed to accommodate an anthropomorphic test device having, on either side, a target point that, when the anthropomorphic test device is positioned in the built-in restraint system in accordance with Test Method 213.4, is below a horizontal plane tangent to the top of the vehicle seat; or (b) a built-in restraint system that is designed to accommodate the anthropomorphic test device specified in subpart N, part 572, chapter V, Title 49 of the Code of Federal Regulations of the United States (revised as of October 1, 2012), or a larger anthropomorphic test device. (17) For the purposes of subsection (15), the height of the continuous seat back shall be measured, in a plane parallel to the surface of the seat back of the built-in restraint system and orthogonal to the vertical longitudinal plane passing through the longitudinal centreline of the restraint system, from the lowest point of the restraint system’s seating surface that is contacted by the buttocks of the seated anthropomorphic test device. (18) Despite paragraph (15)(b), if a built-in restraint system or built-in booster seat provides surfaces for the support of the sides of the torso, and those surfaces extend at least 100 mm forward from the padded surface of the portion of the restraint system or booster seat provided for the support of the head of the anthropomorphic test device, the restraint system or booster seat may have a continuous seat back width of at least 150 mm. (19) Every built-in restraint system and built-in booster seat shall have the following information stitched onto it, indelibly moulded into or onto it, or indelibly printed on a label affixed to it in a permanent manner: (a) a statement that indicates (i) in units based on the International System of Units and in imperial units, the mass and height ranges of the persons for whom the manufacturer recommends the restraint system or booster seat, and (ii) in the case of a booster seat, that the booster sea
