To get UN R129-approved, the Belt Guard has to comply with strict specifications regarding size, functionality as well as ease of opening. And of course, as a product like the Belt Guard can only be approved as part of a child car seat approval, it has to pass the UN R129 crash tests.
If needed, the Belt Guard can also be opened by an adult if the internal harness is still closed and tightened. For this, you would have to push the shoulder belts closer together, so that there is less tension on the Belt Guard. Then, you could rotate the right side upwards slightly and the left side downwards and then pull the two parts apart.
In the ECE R44-04 regulation, which is older than UN R129, no approval mechanisms for such products were provided.
The Belt Guard has been crash-tested as part of the UN R129 approval, meaning in a frontal impact test at 50 km/h. In addition, we have done our own crash-testing on the Belt Guard in the same way as we have done it on our other accessories: in a frontal impact at 70 km/h.
The Belt Guard is only to be opened when the internal harness is not tightened or if the belts are unbuckled. When doing so, the Belt Guard typically automatically slides open. If it does not, you can easily rotate the right side upwards slightly and the left side a downwards and then pull the two parts apart.
On the BeSafe toddler seats you will find Velcro under the shoulder pads. Open the bottom of that Velcro and place each part of the Belt Guard between the Velcros of the shoulder pads. For the right angle, make sure that the shape of the Velcros on the Belt Guard parts follow the shape of the Velcro stripes on the shoulder pads. Align the Belt Guard with the bottom of the shoulder pads. After attaching the Belt Guard parts, make sure to close the Velcro strips of the shoulder pads firmly.
No, the BeSafe Belt Guard is only to be used with BeSafe toddler seats.
