Abstract |
OBJECTIVE: The objective of this study was to evaluate the far-side occupant kinematics in low-speed lateral pulses with and without a seatbelt system. METHODS: The kinematics responses of three volunteers and a Hybrid III were compared in three low-to-moderate lateral pulses. The parameters evaluated were pulses and belt usage. A total of 24 tests were carried out in a side-impact sled. The subjects consisted of two 50th-percentile males (Vol 1 & 2), one 5th-percentile female (Vol 3), and a Hybrid III 50th-percentile male (ATD). All subjects were seated in a far-side impact. Three low speed pulses were used: Pulse 1: a 4 g at 6 km/h, Pulse 2: 4 g/8 kph followed by a -2.5 g pulse to simulate a low curb impact, and Pulse 3: a 4 g's pulse at 10 km/h. In addition, the kinematics result from Pulse 2 was used to assess the performance of a human model. The human model was developed by TNO. RESULTS: For all three pulses, the peak head lateral displacement was greater with the 5th female (Vol 3) than the male volunteers. The ATD results in the 6 and 10 km/h pulses were comparable to the volunteers. However, in Pulse 2, the ATD motion was higher than the volunteers. CONCLUSION: The results obtained in this study suggest the Hybrid III is a somewhat conservative device for an evaluation of occupant kinematics in low-speed lateral pulses. The human model also seemed to be representative of volunteer kinematics. Language: en |
