Motor Vehicle Restraint Systems and Booster Seats Safety Regulations (SOR/2010-90)

Marginal note:Surface contactable by head

313. Every surface of an infant restraint system that is contactable by the head of an anthropomorphic test device positioned in the restraint system in accordance with subsection 4.5.2 or 4.6.2 of Test Method 213.1 must be covered with slow-recovery, energy-absorbing material that, when tested in accordance with section 6 of Test Method 213.1, has

• (a) a resistance of not less than 4 kPa but not more than 70 kPa at 25% of compression-deflection resistance;

• (b) a thickness of not less than 12 mm, if the material has a resistance of not less than 12 kPa but not more than 70 kPa at 25% of compression-deflection resistance; and

• (c) a thickness of not less than 19 mm, if the material has a resistance of not less than 4 kPa but less than 12 kPa at 25% of compression-deflection resistance.

Marginal note:Inversion testing

314. An infant restraint system that is subjected to an inversion test in accordance with section 7 of Test Method 213.1 must not fall out of the aircraft passenger seat belt, and the anthropomorphic test device must not fall out of the restraint system, at any time during the rotation or three-second immobilization period referred to in that section.

Marginal note:Dynamic testing

• 315. (1) An infant restraint system that is subjected to a dynamic test in accordance with section 4 of Test Method 213.1 must, if the adjustment position of each component of the restraint system is in accordance with the manufacturer’s instructions,

  • (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, except that, if the restraint system has a means of automatically repositioning the seating surface to allow the anthropomorphic test device to move from a reclined position to a more upright position and back to a reclined position during the test, the seating surface does not have to remain in the same adjustment position during the test as it was in immediately before the test began;

  • (c) 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) 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) 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;

  • (f) not allow the angle between the vertical and the back and head support surface, measured 240 mm above the seating surface, to be more than 70° at any time during the test;

  • (g) 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

  • (h) 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:Dynamic testing — levelling device

  (2) An infant restraint system that is subjected to a dynamic test in accordance with section 4 of Test Method 213.1 must conform to the requirements of paragraphs (1)(a) and (b) if the restraint system is equipped with a levelling device and the adjustment position of each component of the restraint system, except the levelling device, is in accordance with the manufacturer’s instructions.

• Marginal note:Continuous seat back

  (3) The continuous seat back referred to in paragraphs (1)(g) and (h) must

  • (a) have a height of at least 500 mm;

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

  • (c) not impose any loads on the top of the head of the anthropomorphic test device during the dynamic test referred to in subsection (1).

• Marginal note:Measurement of height — paragraph (3)(a)

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

  (5) Despite paragraph (3)(b), if the infant 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 specified in paragraph (3)(a).

• Marginal note:Restraint system with means of automatic repositioning

  (6) If an infant restraint system that has a means of automatically repositioning the seating surface is subjected, in any adjustment position, to a dynamic test in accordance with section 4 of Test Method 213.1, an opening that is exposed and larger than 6.4 mm before the test must not become smaller during the test as a result of the movement of the seating surface relative to the other parts of the restraint system.
