TITLE: FMVSS INTERPRETATION

TEXT: Thank you for your letter of September 19, 1972, to Mr. Francis Armstrong, concerning seat belt model designations.

The intent of paragraph S4.1(k) of Federal Motor Vehicle Safety Standard No. 209 is to require different model numbers for seat belt assemblies that differ in basic design concept. We would not consider belt assemblies that differ only in the size or number of cross threads in the webbing to be separate models. On the other hand, a belt assembly that incorporates a push button type buckle would be considered a separate model from an assembly that incorporates a lift cover type buckle.

If we can be of further assistance, please do not hesitate to contact us.
