CHARACTERIZATION OF AUTOMOTIVE SEAT BELT BUCKLE INERTIAL RELEASE

The objective of this research program was to determine the dynamic conditions under which a restraint system will unlatch due to inertial loading. This question must be answered in order to provide the basis for understanding whether or not inertial release of seat belt buckles can occur in real-world automobile collisions. Controlled laboratory dynamic tests were conducted on several different manufacturers' seat belt buckles to determine the conditions which would result in inertial unlatching. The two key variables evaluated were: (1) Velocity Change at Release; (2) Acceleration History. These tests provided a characterization of the acceleration and delta velocity conditions to inertially unlatch a wide range of seatbelt buckles. Future research is required to determine if the conditions actually occur in real-world collisions. (A) For the covering abstract of the conference see TRIS 00663162.
