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

Marginal note:Removable surfaces

513. A surface of a restraint system for disabled persons that is placed in front of the disabled person must be removable when the restraint system is installed in a vehicle, unless the surface is designed to restrain the person.

Marginal note:Cross-sections of surface

514. Every horizontal cross-section of a surface of a restraint system for disabled persons that is designed to limit the forward movement of a disabled person must be flat or concave, and every vertical longitudinal cross-section of that surface must be flat or convex with a radius of curvature of the underlying structure of not less than 50 mm.

Marginal note:Rigid structural elements

515. Any rigid structural element underlying a contactable surface of a restraint system for disabled persons must not have

• (a) a protrusion, with any padding or flexible overlay material removed, of more than 9.5 mm; or

• (b) an exposed edge with a radius of less than 6.4 mm.

Marginal note:Surface contactable by head — custom restraint system for a disabled person

• 516. (1) Every surface of a custom restraint system for a disabled person that is contactable by the head of a disabled person when the person is positioned in the restraint system must be covered with slow-recovery, energy-absorbing material that, when tested in accordance with section 7 of Test Method 213.3, 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:Surface contactable by head — mass-produced restraint system for disabled persons

  (2) Every surface of a mass-produced restraint system for disabled persons that is contactable by the head of a disabled person when the person is positioned in the restraint system in accordance with the instructions referred to in paragraph 524(1)(b) and the restraint system is adjusted in accordance with the instructions referred to in paragraph 524(1)(c) must be covered with slow-recovery, energy-absorbing material that, when tested in accordance with section 7 of Test Method 213.3, 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.
