Özet

This paper presents the development of an energy-absorbing car seat with fixed recliner that can mitigate whiplash risk in rear-end collisions. The developed seat has a proactive head restraint and an energy-absorbing device under the seatpan. The seat produces neck shear forces lower than 120 N when subjected to the medium and high severity crash pulses of EuroNCAP. Additionally, a very high severity crash pulse with a velocity change (delta-V) of 35 km/h is applied and the largest neck-shear force at this severity is only 189 N. The developed seat gets maximum points from the dynamic whiplash assessment protocol of European New Car Assessment Programme (EuroNCAP).
