The development of SAFER HBM started in 2008, when the first human body modelling (HBM) project was initiated by members of the SAFER - Vehicle and Traffic Safety Centre. The latest version of SAFER HBM, version 11 presented in this report, was developed to be a stand-alone model, free from proprietary data from the original THUMS model, with special focus on injury prediction for reclined occupants in front crashes. The objective of this report is to describe the SAFER HBM updates from version 10 to version 11, and the additional validation that has been carried out, and is summarized, in a validation repository.
