Just happened to dig up an old Threat, in which it was about the integrated child seats. So it’s probably that everyone with the number 02 at the beginning are not allowed anymore?? Then mine is no longer usable. Just over the built-in child seat I was so happy. According to the old Threat, however, there are probably approved ones that would fit? Probably with 03 at the beginning? Does anyone have something else?? The conversion should be easy… I would be happy if someone who can turn in a usable one would be able to contact me.
