Abstract

The IIHS (Insurance Institute for Highway Safety) introduced the small overlap frontal crash test in 2012. The small overlap frontal crash performance is evaluated in terms of injury assessment, structural assessment, and restraint and dummy kinematics. The test involves limited horizontal structural engagement at the corner. The small overlap condition is designed such that longitudinal structural members of vehicle have less interaction than during the IIHS’ moderate overlap frontal test. Dummy kinematics can be affected if the structure does not absorb the crash impact energy or the driver airbag is not in position to provide restraint to the head. In the IIHS Status Report newsletter (Issue 47, No. 6 August 14, 2012) the IIHS’ small overlap test results showed that most of the injury assessments were similar to that of the IIHS’ moderate offset crash tests. However, vehicle structure and dummy kinematics were more severe in the small overlap as compared to the IIHS’ moderate offset crash test. This study provides restraint system development guidance for dummy head protection in the IIHS’ small overlap crash condition.
