Kral, J., Kondel, T., Morra, M., Cassatta, S. et al., "Safety Belt Testing Apparatus," SAE Technical Paper 2015-01-1485, 2015, doi:10.4271/2015-01-1485.
A new apparatus for testing modern safety belt systems was developed. The apparatus design, dynamic behavior and test procedure are described. A number of tests have been conducted using this apparatus. These tests allowed identification of key performance parameters of pretensioners and load limiting retractors which are relevant to occupant protection in a crash environment. Good test repeatability was observed, which allowed comparison of different safety belt designs. The apparatus may be used for better specification and verification of safety belt properties on a subsystem level as well as for the validation of CAE models of safety belts used in simulations of occupant response to crash events.
