A Study on the Development of Aluminum Sea Frame for Commercial Bus

This study presents the development of a new aluminum seat frame for commercial bus which is lighter than steel seat frame about 40%. The seat components i.e. back frame, main cross pipe and side frame are designed to satisfy several FMVSS regulations through tests and numerical analyses. The analysis was done for seat belt anchorage test and back moment test. The final design was used to produce a sample seat. Substitution of the material resulted in a weight reduction effect with equivalent strength characteristics.
