Common use of Class B devices Clause in Contracts

Class B devices. The child restraint shall be firmly secured and webbing, as specified in Annex 13 to this Regulation, shall be passed through the lock-off and frame following the routing described in the manufacturer's instructions. The belt shall pass through the testing equipment as described in Figure 6 below and be attached to a mass of 5.25 ± 0.05 kg. There shall be 650 ± 40 mm of free webbing between the mass and the point where the webbing leaves the frame. The lock-off shall be fully applied and a xxxx made on the belt where it enters the lock-off. The mass shall be raised and released so that it falls freely over a distance of 25 ± 1 mm. This shall be repeated 100 times ± 2 at a frequency of 60 ± 2 cycles per minute, to simulate the jerking action of a child restraint in a car. A further xxxx shall be made on the belt where it enters the lock-off and the distance between the two marks shall be measured. The lock-off device must cover the full width of the webbing in the installed condition with 15 kg dummy installed. This test is to be conducted using the same webbing angles as those formed in normal use. The free end of the lap belt portion shall be fixed. The test shall be conducted with the child restraint system firmly attached to the test bench used in the overturning or dynamic test. The loading strap can be attached to the simulated buckle. roller guide roller bar mass 25 mm to child restraint frame and lock-off Drop height of mass = 25 mm Distance from roller bar to roller guide = 300 mm Using strap of the webbing specified for the standard seat belt as defined in Annex 13.
