9.2.3 Test method for effectiveness of restraint system, roll-over test
Initially place the test dummy centrally on the seat unit with the 225 mm axis against the backrest and attach the restraint system in accordance with the manufacturer’s instructions. Fasten any waist restraints around the torso section of the test dummy so that any slackness is removed and the waist is positioned above the leg stumps. If the crotch restraint is adjustable, adjust it so that any slackness is removed. Where shoulder straps are fitted, place a 30 mm cuboid spacer block, made of a hard smooth material, on each shoulder of the test dummy. Adjust each shoulder strap so that any slackness is removed. Remove the spacers.
A means of rotation is used to rotate the product smoothly through 360° at a speed of (4 ± 0,5) RPM in a forward and reverse direction.
Rotate the seat through 360° in a forward direction. If necessary reposition the test dummy to its initial position without altering the adjusters on the restraint system.
Rotate the seat through 360° in the reverse direction. If necessary reposition the test dummy to its initial position without altering the adjusters on the restraint system.
Repeat the forward and reverse rotation cycles for two more sequences, giving a total of 3 forward and 3 reverse rotations. If necessary, after each rotation, reposition the test dummy to its initial position without altering the adjusters to the restraint system.
The adjusting device shall be placed on a vertical piece of strap one end of which bears a 5 kg load (guided in a manner which prevents the load from swinging and the strap from twisting). The free end of the strap from the adjusting device shall be mounted vertically upwards or downwards as it is on the seat. The other end shall pass over a deflector roller with its horizontal axis parallel to the plane of the section of the strap supporting the load, the section passing over the roller being horizontal.
