Motor Vehicle Restraint Systems and Booster Seats Safety Regulations

Version of section 215 from 2010-05-12 to 2013-06-18:

Marginal note:Dynamic testing
  •  (1) A child restraint system that is subjected to a dynamic test in accordance with section 4 of Test Method 213 must, when in any adjustment position for which there is no warning under subparagraph 218(1)(e)(iii),

    • (a) exhibit no complete separation of any load-bearing structural element, and no partial separation exposing a surface with

      • (i) a protrusion of more than 9.5 mm, or

      • (ii) a radius of less than 6.4 mm;

    • (b) remain in the same adjustment position during the test as it was in immediately before the test began;

    • (c) except in the case of a restraint system tested with the anthropomorphic test device specified in subpart S, part 572, chapter V, title 49 of the Code of Federal Regulations of the United States (revised as of October 1, 2009), limit the resultant acceleration at the location of the accelerometer mounted in the upper thorax of the anthropomorphic test device to not more than 60 g, except for intervals of not more than 3 ms;

    • (d) except in the case of a restraint system tested with the anthropomorphic test device specified in subpart S, part 572, chapter V, title 49 of the Code of Federal Regulations of the United States (revised as of October 1, 2009), limit the resultant acceleration of the centre of gravity of the head of the anthropomorphic test device during the movement of the head towards the front of the vehicle 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;

    • (e) subject to subsection 216(2), limit the movement of the head of the anthropomorphic test device towards the rear of the restraint system by means of a continuous seat back that is an integral part of the restraint system; and

    • (f) subject to subsection 216(2), limit the rotation of the head of the anthropomorphic test device towards the rear of the restraint system, in its midsagittal plane, by means of a continuous seat back that is an integral part of the restraint system, so that the angle between the head and the torso is at no time during the test more than 45° as compared to the angle between the head and the torso prior to the test.

  • Marginal note:Continuous seat back

    (2) The continuous seat back referred to in paragraphs (1)(e) and (f) must have

    • (a) a height

      • (i) of at least 500 mm, in the case of a child restraint system recommended by the manufacturer for use by a child whose mass is 18 kg or less, or

      • (ii) of at least 560 mm, in the case of a child restraint system recommended by the manufacturer for use by a child whose mass is more than 18 kg; and

    • (b) a width of at least 200 mm, measured in the horizontal plane at the height specified in paragraph (a).

  • Marginal note:Measurement of height — paragraph (2)(a)

    (3) The height referred to in paragraph (2)(a) must be measured in a plane parallel to the surface of the seat back of the child 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.

  • Marginal note:Exception

    (4) Despite paragraph (2)(b), if the child restraint system 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 provided for the support of the head of the anthropomorphic test device, the restraint system may have a continuous seat back width of not less than 150 mm, measured in the horizontal plane at the height referred to in paragraph (2)(a).

  • Marginal note:Belt

    (5) Every belt that is part of a child restraint system and that is designed to restrain a child in the restraint system must not, when subjected to a dynamic test in accordance with section 4 of Test Method 213, impose on the anthropomorphic test device any loads that result from the mass of the restraint system or the mass of the seat back of the standard seat assembly.
