In order to explore the kinematic responses and injury mechanisms of far-end elderly occupants under the current Euro-NCAP side impact condition, a sled model was established using the elderly human body model CHARM-70, then the Advanced European Mobile Deformable Barrier (AE-MDB) side impact and oblique pole side impact finite element model were established, to conduct the vehicle collision simulation, and extract the acceleration pulse at the bottom of the B-pillar on the non-collision side. Finally, the single-occupant and double-occupant sled simulation models were established based on the THUMS_AM50_V4.0 human body model and the elderly human body model CHARM-70, to conduct the AE-MDB side impact and oblique pole side impact simulation. The results show that in the side impact, the seat belt can’t effectively limit the lateral offset caused by the inertia of the far-end occupant; in the single-occupant sled simulation, the head and neck injury values of the far-end elderly occupants are far less than the threshold, but the chest suffers serious rib fracture; in the double-occupant sled simulation, the far-end elderly occupants suffer severe head and chest injuries.
