Dynamic tests in accordance with the FMVSS 213 (CMVSS) regulations. Required in the United States, Canada and countries of South America. Conducted on the basis of regulations modified once a year by independent engineers from various organisations dealing with road safety. The regulations and their modifications are intended to force manufacturers to build the safest possible restraint systems. Smart Kid Belt is regularly tested in line with these regulations in the best U.S. research laboratories of MGA and Calspan. Due to regulatory differences and higher requirements during dynamic tests, there are only a few devices on the market that, besides ECE R44-04, also comply with FMVSS 213 in the category of older children. Smart Kid Belt is one of such devices. As shown by the FMVSS 213 crash test reports, the results obtained by Smart Kid Belt are record-breaking, similarly to ECE R44-04 tests.
