Motor Vehicle Restraint Systems and Booster Seats Safety Regulations

Version of section 407 from 2010-04-29 to 2010-05-11:

The following provision is not in force.

Marginal note:Dynamic testing

 A booster seat that is subjected to a dynamic test in accordance with section 3 of Test Method 213.2 must, when in any adjustment position,

  • (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 a component of the booster seat used to ensure that the vehicle seat belt is adjusted as recommended by the manufacturer;

  • (c) except in the case of a booster seat 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 booster seat 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) except in the case of a booster seat 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), not allow any portion of the head of the anthropomorphic test device to pass through the vertical transverse plane — shown as the forward excursion limit in Figures 5 and 6 of Schedule 7 — that is 813 mm forward of the Z point on the standard seat assembly, measured along the SORL; and

  • (f) except in the case of a booster seat 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), not allow either knee pivot point to pass through the vertical transverse plane — shown as the forward excursion limit in Figures 5 and 6 of Schedule 7 — that is 915 mm forward of the Z point on the standard seat assembly, measured along the SORL.
